The present invention solves the drawbacks of the current drying devices. It is a combined compressor-ejector heat pump system that integrates state-of-the-art technologies of the vapor compression cycle (heat pump), ejector cycle, and heat pipe (HP) to solve the high energy consumption and carbon emissions associated with traditional dryers. Thus, the objective of the present invention is to develop a vacuum dryer machine that could cut down on energy consumption and carbon emissions and operate reliably over a wide range of operating conditions.
The background description provided herein gives context for the present disclosure. Work of the presently named inventors, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art.
Conventional vacuum wood dryers are typically batch, convective dry kilns. The green lumber (wood boards) with a high moisture content of up to 250% is stacked and separated in layers by metal plates. These wood boards are moved into a chamber, the doors closed, and lumber is exposed to a drying schedule. Steam is moved into chamber and through the air space formed by the metal plates and metal plates to heat up the lumber, transferring thermal energy to remove the moisture. This type of drying suffers from high operating costs because of the inefficient heating process, which accounts for over 55% of end-use onsite energy. Also, over three-quarters of the heating energy is supplied by steam produced onsite using gas furnaces, increasing carbon emissions.
The present invention relates to a lumber dryer that integrates the state-of-the-art technologies of an electrical-driven vapor compression cycle, ejector, and super-conductance oscillating heat pipe (OHP) with innovative designs of cap-end vapor refrigerant condensation heating, and highly-efficient water vapor condensation energy recovery unit to achieve extra-high energy efficiency while operating reliably over a wide range of operating conditions and achieves zero carbon emission. While the proposed dryer provides uniform heating power for wood drying, which can significantly shorten drying time from several weeks to several days, it can efficiently utilize the cooling and heating energy, achieving a closed energy loop.
Drying of materials is common in many industries, such as food, chemical, waste, and pharmaceutical product processing. It is an energy-intensive operation that could consume up to 60% of the total energy input required for the entire process. It also contributes to carbon emissions and greenhouse gases. Enhancing energy efficiency and reducing the emissions associated with this technology will significantly benefit energy conservation and greenhouse gas reduction, hence achieving the Federal Sustainability Plan, which aims to reach zero emissions by 2050.
Thus, there is a need in the art for an apparatus to dry materials that is energy efficient with a reduction in emissions and greenhouse gases.

An oscillating heat pipe (OHP), also known as a pulsating heat pipe, is only partially filled with liquid working fluid. The pipe is arranged in a serpentine pattern in which freely moving liquid and vapor segments alternate. Oscillation takes place in the working fluid; the pipe remains motionless. A compressor is defined as a device that packs molecules in the gas-based refrigerant tightly together, a process that raises both the temperature and pressure of the refrigerant. A condenser is the outdoor portion of an air conditioner or heat pump that either releases or collects heat, depending on the time of the year. An ejector is defined as utilizing a principle of operation based on the Venturi effect of a converging-diverging nozzle to convert the pressure energy of a motive fluid, functioning as a primary flow, to kinetic energy to entrain a suction fluid, functioning as a secondary flow, and then recompress the mixed fluids by converting kinetic energy back into pressure energy.
Ejectors are thermally activated static compressors and consist of a nozzle (a primary convergent-divergent nozzle) embedded in a main, generally cylindrical, body. The compression effect results from the interaction of the two fluid streams. The motive stream is at high pressure and is produced in a generator using a heat source. This heat source can come from low-grade temperature heat. Therefore, ejectors thus have the advantage that they can be driven with waste heat and used as heat pumps in appropriate cycles to produce heat upgrading, cooling, or refrigeration effects, provided as long as a thermal source is available.
The throttle valve is a mechanical device whose function is to regulate and maintain the downstream pressure so that the inlet conditions for the expansion are constant. It does this by introducing a flow restriction, inducing a significant localized pressure drop in the refrigerant. The evaporator holds the chilled refrigerant that the compressor moves into it. As the air from the blower fan moves over the coil, the cold refrigerant removes the heat from a building's air. The refrigerant becomes warmer and travels to the condenser coil outdoors. With a heat pump, the process reverses in the winter, and the evaporator coil expels heat from the refrigerant into the building instead of absorbing it and taking it outdoors.
The compressor 44 is electrically driven to compress the refrigeration vapor generated from the first compact thin-film evaporator 40 having an air flow 42. The energy added by the compressor 44 and the thermal energy received from the first compact thin-film evaporator 40 is in a low-pressure liquid state 38 that is then converted into a compressed high-pressure refrigerant vapor in a high-pressure vapor state 46, which is used to power the ejector 48.
In the ejector 48, the compressed refrigerant vapor goes through a convergent-divergent nozzle, and a supersonic flow is produced, resulting in low-pressure vapor in the ejector 48 that is in fluid connection with the second compact thin-film evaporator 50, where refrigerant evaporation occurs, and additional thermal energy is added to the system.
The stream brings all the energy in a hot stream from the compressor 44, the first compact thin-film evaporator 40, and the second compact thin-film evaporator 50 to the two cap-end refrigerant vapor condensers 26 in the form of high-temperature vapor 62, where the refrigerant vapor condenses, and the thermal energy is released and transferred to the wood or lumber 76 by flat-plate OHPs that are generally indicated by numeral 51. The inner surface of the condenser section of OHPs 30 can be selected from the commercially available condensation surfaces to effectively condense vapor to liquid, such as, but not necessarily, a grooved enhanced condenser section of OHPs 30.
The released thermal energy due to condensation is directly transferred to the evaporator section 28 of flat-plate OHPs 51 located in the OHP housing 32. The OHPs housing 32 provides perfect thermal contact between OHPs and cap-end refrigerant vapor condensers 26, allowing heat transfer efficiently. Through the oscillating motion and phase change heat transfer of the working fluid in the flat-plate OHPs located in the OHP housing 32, the thermal energy is efficiently transferred to the OHP's condenser section 30, which are in direct contact with lumber or wood 76 to uniformly heat up and dry the lumber or wood 76 in the drying vessel 64.
Liquid from drying vessel 64 is provided to a condensed liquid tank 60. This liquid 34 from the condensed liquid tank 60 passes to a first expansion valve 36 that is in a fluid relationship with the first compact thin-film evaporator 40 and provides low-pressure liquid thereto. Moreover, this liquid 34 from the condensed liquid tank 60 passes to a second expansion valve 58 that is in a fluid relationship with the second compact thin-film evaporator 50 and provides a low-pressure liquid 38 thereto.
The first compact thin-film evaporator 40 includes a fan 42 that is used to add more energy from the atmosphere at the startup (base load) when moisture has not been regenerated yet in the drying vessel 64. When the cycle reaches a steady state, moisture starts to be released from the wood or lumber 76 in the drying vessel 64 and flows through small gaps formed by the thin flat-plate OHPs 51 located in the OHP housing 32, which provides heating energy and functions as spacers simultaneously to the moisture condenser 22 through the moisture outlet of the drying vessel 66.
In the moisture condenser 22, the moisture is condensed into water in a condensed water line 16, and the released thermal energy is collected by the cooling fluid 54, which is thermally connected with the first compact thin-film evaporator 40 and the second thin-film evaporator 50, where the thermal energy is then recovered and pumped back to the system. At the same time, the condensate is collected in a water reservoir 14 as a by-product (potable water).
There is cooling fluid 54 that circulates from outlet 18 into the fluid pump 56 through the second compact thin-film evaporator 50 and then the first compact thin-film evaporator 40 and then returns into an input 20 of the fluid pump 56.
A vacuum pump 12 is used to remove the non-condensable gases. Using the pressure and temperature readings in drying vessel 64 and moisture condenser 22, the amount of non-condensable gases can be readily determined, which is similar to a typical heat pipe. The vacuum pump 56 is switched on only when the non-condensable gases in the system reach a level. In this way, the power usage from the vacuum pump 12 is significantly reduced, which is much smaller than commercially available vacuum wood dryers in the marketplace.
Also, this system 10 can optionally be equipped with a smart control system (SCS) using machine learning and optimization algorithms (not shown). The SCS will identify the operating parameters that optimize product quality and reduce energy consumption and operation costs simultaneously.

This heat pump ejector vacuum dryer includes a vapor compression cycle, an ejector, and preferably, but not necessarily includes (depending on the application, oscillating heat pipes (OHP), and cap-end condensers. These three technologies are integrated effectively with a highly efficient vapor-water condensation energy recovery unit. The ejector 48 is effectively integrated into the vapor compression cycle to utilize further the thermal energy released in a condenser 30 in a typical vapor compression cycle to entrain additional thermal energy into the system, and both “hot” and “cold” thermal energies are efficiently utilized. This novel high-temperature vapor-compression-ejector heat pump uses low Global Warming Potential (GWP) refrigerants (<10) and zero Ozone Depletion Potential (ODP). While the flat-plate OHP can function as thin spacers for stacking lumber 68, OHP's extra-high effective thermal conductivity can produce an extra-high level of temperature uniformity of lumber or wood 76 in the drying vessel 64, which can significantly reduce drying time. The thin-film evaporator utilizing thin-film evaporation can result in highly efficient compact evaporators 40 and 50, which can efficiently utilize the thermal energy from the ambient air as well as the thermal energy recovered from the wood water vaporization through a moisture condenser. The refrigerant vapor condenser 30 utilizes a state-of-the-art engineered surface to enhance the condensation of refrigerant vapor coming from ejector 48 and compressor 44, and the thermal energy released from the condensation can be efficiently and uniformly transported to the wood lumbers through the high-conductance flat-plate OHPs 51 in the vessel.

The condenser header 202 also provides liquid to a first expansion valve 36 and is in fluid communication therewith and reduces the pressure of the liquid. The output of the first expansion valve 36 lowers the pressure of the liquid and is connected to the input of a first compact thin film evaporator 40 that is preferably, but not necessarily, located at the bottom of the flat plate drying vessel 206. This drying vessel might have any type of shape such as round, square, and so forth and should not be limited by any means to being a flat plate. This first compact thin film evaporator 40 creates low-pressure vapor and is connected in fluid relationship to the input of a compressor 44 that converts the low-pressure vapor into high-pressure vapor. The output of the compressor 44 is connected in fluid relationship to the ejector 48 and provides the primary stream into an input for the ejector 48.
The moisture is condensed by touching the surface of the first compact thin film evaporator 40. The output of the first compact thin film evaporator 40 provides a low-pressure vapor and is in a fluid relationship with a compressor 44. The compressor 44 converts the low-pressure vapor into high-pressure vapor and provides the primary stream to the ejector 48 in addition to the secondary stream from the second compact thin film evaporator 50. The ejector 48 provides a high-pressure vapor stream 62 that is returned to the flat plate drying vessel 206. The liquid extracted from the wood or lumber 76 in the drying vessel 206 goes into a water reservoir 14. The temperature difference between the flat plate condenser 204 and the first compact thin film evaporator 40 reduces the pressure inside the drying vessel 206 below the atmospheric pressure. This reduction in the pressure increases the moisture removal rate as part of the drying process and, therefore, reduces the power consumption and drying time. The aspect of

The high-temperature vapor 62 releases thermal energy to dry the materials, e.g., wood chips 304, and the moisture 306 is removed. The stationary tube condenser 302 is connected in fluid communication to an input for a second expansion valve 58 that converts liquid into low-pressure liquid. The output for the second expansion valve 58 is connected in fluid connection to a second compact, thin film evaporator 50 that converts the liquid into a low-pressure vapor state that creates a secondary pressure stream for input into an ejector 48.
The stationary tube condenser 302 also provides liquid to a first expansion valve 36 and is in fluid communication therewith and reduces the pressure of the liquid. The output of the first expansion valve 36 lowers the pressure of the liquid and is connected to the input of a first compact thin film evaporator 40 that is preferably, but not necessarily, located at the bottom of the fixed drum 308. This first compact thin film evaporator 40 creates low-pressure vapor and is connected in fluid relationship to the input of a compressor 44 that converts the low-pressure vapor into high-pressure vapor. The output of the compressor 44 is connected in fluid relationship to the ejector 48 and provides the primary stream into an input for the ejector 48.
The moisture is condensed by touching the surface of the first compact thin film evaporator 40. The output of the first compact thin film evaporator 40 provides a low-pressure vapor and is in a fluid relationship with a compressor 44. The compressor 44 converts the low-pressure vapor into high-pressure vapor and provides the primary stream to the ejector 48 in addition to the secondary stream from the second compact thin film evaporator 50. The ejector 48 provides a high-pressure vapor stream 62 that is returned to the stationary tube condenser 302.
The liquid extracted from the materials, e.g., wood chips 304, obtained from the perforated rotating drum 312 and into the bottom of the fixed drum 308, goes into a water reservoir 14.
A vacuum pump 12 is used at the beginning of the operation to create a vacuum effect that reduces the pressure before the atmospheric pressure. The temperature difference between the first compact thin film evaporator 40 and the stationary tube condenser 302 would be able to maintain this vacuum pressure, significantly reducing power consumption.
The aspect of
An important aspect of the present disclosure includes that Both “hot” and “cold” thermal energy is fully utilized. When the thermal energy is pumped to a higher heat source, i.e., the dry vessel, it is fully utilized to heat up and dry the material, e.g., wood or lumber 76. At the same time, the thermal energies removed from both evaporators 40 and 50 (the cooling capacities) are used to condense the moisture generated from the dry vessel and form the pressure difference to pump the moisture from a hot dry vessel to a cold condenser. This closed-loop results in a further increase in thermal efficiency.
Another important aspect of the present invention is that oscillating heat pipes (OHPs) are heating elements and spacers, significantly reducing the drying time with no wood or lumber 76 cracking. A big challenge in traditional wood dryers is to prevent wood cracking due to the thermal stress produced by the temperature difference during the drying process. The flat-plate OHPs as heating elements and spacers will provide a high level of temperature uniformity, and thermal stress in the lumber can be significantly reduced during the drying process, preventing cracking.
An additional aspect of the present disclosure is this is an eco-friendly system that can result in extra-high thermal efficiency. For a typical vapor-compression cycle, the compressed vapor flows into the condenser, where heat is dumped into the ambient air. For the proposed system, the compressed refrigeration vapor, which brings the thermal energy received from the first compact thin film evaporator 40 and the compressor 44 work, is further utilized to power the ejector 48, which pumps additional thermal energy from the second compact thin film evaporator 50, resulting in high energy efficiency. It can directly replace the gas-fired boilers without system retrofitting and significantly reduce the CO 2 emission in wood or lumber 76 drying. With the aim of decarbonization, only electrical energy will be utilized to drive the system.
Still, yet another aspect of the present disclosure is that the power the vacuum pump 12 uses can be significantly reduced. For a typical vacuum dryer, the vacuum pump is used to pump moisture from the drying vessel and, at the same time, maintain a higher level of vacuum, resulting in a high operation cost, which explains why a typical vacuum dryer is so expensive. For this system, the vacuum pump 12 is used only to remove the non-condensable gas. In other words, the vacuum pump 12 in this system runs only at the beginning when the wood or lumber 76 is loaded, or some non-condensable gas from wood is produced during the operation. The moisture flow from the drying vessel to the moisture condenser is by the evaporation-condensation closed loop, similar to a typical heat pipe. Therefore, the power of the vacuum pump can be significantly reduced.
In addition, an outhandling feature is that a by-product (freshwater) can be produced. For a typical wine barrel wood, the moisture should be reduced from about 50% to 12%. The proposed dryer with a typical size, for example, a load capacity of 4000 Board Feet (9.44 m3), can generate fresh water up to 294,000 gallons of water per year per dryer at an annual production rate of 1,100 MBF.
From the foregoing, it can be seen that the present disclosure accomplishes at least all of the stated objectives.
