1. Technical Field
The present invention relates to an energy recycling type dust removing processing system for removing contaminated material in high temperature contaminated gas by recovering energy and simultaneously processing a particulate air contaminated material, a gaseous air contaminated material, and an offensive odor material in a process of processing high temperature exhaust gas containing high viscosity oil droplets and fine dust, and an inertial impact type energy recovery and dust removal apparatus.
2. Description of the Related Art
Generally, as technologies for processing the exhaust gas generated in various industrial fields and including an air contaminated material, a technology for processing a particulate air contaminated material, an electrostatic precipitator, a filter dust collector, or the like, has been used. Furthermore, a technology for processing a gaseous air contaminated material, an absorption method, an adsorption method, a catalytic oxidizer, or the like, has been used. However, in the case of processing the exhaust gas containing a large amount of high viscosity oil droplets, fine dust, and a gaseous air contaminated material, at the time of applying a general processing technology, the processing efficiency decreases and the maintenance cost increases.
Particularly, at the time of using a general processing apparatus as an apparatus for processing the exhaust gas generated at the time of biomass burning and containing fine dust and oil droplet including a large amount of pyroligneous liquor generated in carbonization process, such as a charcoal kiln for charcoal production or a charcoal kiln for fomentation, processing efficiency decreases and processing costs increase. The reason that the processing efficiency decreases and the processing costs increase is that the high viscosity oil droplets adhere to a surface of the electrostatic precipitator, such that it is not easily separated or the high viscosity oil droplets close filtering pores of a filter cloth of the filter dust collector to increase differential pressure, such that it is not processed or separated, whereby the electrostatic precipitator or the filter dust collector should be replaced.
In addition, at the time of use of a general air contaminated material processing apparatus as an apparatus for processing the exhaust gas containing oil droplets generated in a process of roasting meat and fine dust or an apparatus for processing oil vapor and exhaust gas generated in a drying process, or the like, of a food processing factory and containing high viscosity and high temperature oil droplet and fine dust, it is difficult to process the exhaust gas containing the oil droplets generated in a process of roasting meat and the fine dust and the oil vapor and the exhaust gas containing the high temperature oil droplets and the fine dust. Further, even in an apparatus for processing the exhaust gas discharged from an industrial facility and containing a large amount oil droplets and oil vapor, an improved processing technology has been demanded.
In order to solve these problems, various processing systems for removing high viscosity oil droplets and fine dust in the exhaust gas of a kiln for charcoal production and a charcoal kiln for fomentation, the exhaust gas of a meat roasting restaurant, the oil vapor generated in a drying process of a food processing factory, and the exhaust gas generated in an industrial facility and containing high viscosity oil droplets and fine dust have been developed, and a technology for improving dust removing efficiency and recovering and recycling energy from high temperature exhaust gas has been required.
An object of the present document is to provide an energy recovery type dust processing system for recovering energy and simultaneously processing a particulate air contaminated material, gaseous air contaminated material, and an offensive odor material in a process of processing high temperature exhaust gas containing high viscosity oil droplet and fine dust in exhaust gas of a kiln for charcoal production and a charcoal kiln for fomentation, exhaust gas of a meat roasting restaurant, oil vapor generated in a drying process of a food processing factory, and exhaust gas generated in an industrial facility and containing high viscosity oil droplets and fine dust.

Furthermore, This present invention is supported by Korea Ministry of Environment as “The Eco-Innovation 21 project (401-112-018)
Here, the high temperature contamination generation source 10 means a contamination generation source discharging a high temperature gas, such as the charcoal kiln for producing charcoal, the meat roasting restaurant, an incineration plant, or the like.
The collecting duct 20 serves to collect the high temperature contaminated gas generated in the high temperature contamination source 10 and including the high temperature dust. As described above, the high temperature contaminated gas collected in the collecting duct 20 is moved to the energy recovery and inertial impact type dust removal unit 30.
The energy recovery and inertial impact type dust removal unit 30 serves to recover the energy of the high temperature contaminated gas to convert the high temperature contaminated gas into middle-low temperature contaminated gas (changes cold water into hot water heat generated at this time) and remove coarse dust in the contaminated gas. The energy recovery and inertial impact type dust removal unit 30 may include the energy recovery apparatus 31, the inertial impact type dust removal apparatus 33, and the inertial impact type energy recovery and dust removal assembly 35 (an integral type). An example of the energy recovery apparatus 31 will be described with reference to
The energy obtained from the energy recovery and inertial impact type dust removal unit 30 is recycled in an energy recycling system 100. The energy recycling system 100 will be described with reference to
The in-flight adsorption apparatus 50 serves to remove fine dust in the contaminated gas in which the coarse dust is removed in the energy recovery and inertial impact type dust removal unit 30 and may include a cyclone apparatus and a chamber 300. The cyclone apparatus, which is an apparatus that removes dust using centrifugal force, moves particulate matter (dust) in a fluid introduced in a tangent line of a cylindrical housing to a wall surface by the centrifugal force and allows the dust moved to the wall surface to drop downward and be collected in a hopper, thereby removing the fine dust. Meanwhile, the chamber will be described in more detail with reference to
When an air inlet is closed in order to block the supply of oxygen in a carbonization process such as in a charcoal kiln, a generated flow rate becomes small. Therefore, in order to supply a constant flow rate to a subsequent processing apparatus, the open damper 51 is opened to supply a constant flow rate to a subsequent processing apparatus. That is, a processed flow rate of the micro dust removal apparatus 60 is allowed to be constant, such that a processing speed is maintained to be constant, thereby increasing the processing efficiency of the micro dust removal apparatus 60.
The micro dust removal apparatus 60 serves to remove micro dust in the contaminated air from which the fine dust is removed by the chamber 300. As the micro dust removal apparatus 60, at least one of a middle performance high temperature type adsorption filter 61, an electrostatic precipitator (ESP) 63, a bag filter dust collector 65, and an electrostatic cyclone 67 may be used.
The unburned material reburning apparatus 70 includes a sensor configured to sense carbon monoxide (CO), hydrocarbon (HC), or the like, which is a combustible material. Therefore, the unburned material reburning apparatus 70 ignites and burns CO or HC using auxiliary fuel when it is sensed that the concentration of CO or HC is at or above a predetermined level, thereby converting CO or HC into carbon dioxide or waterwhich is a harmless material. The unburned material reburning apparatus 70 may be installed at the front end of the open damper 51 in the case that the pyroligneous liquor is recovered or be installed between the collecting duct 20 and the energy recovery and inertial impact type dust removal unit 30 in the case that the pyroligneous liquor is not recovered.
The self flow rate controlling blowing apparatus 80 opens the open damper 51 if the introduced flow rate is low, in order to maintain a constant flow rate and sustain the efficiency of the micro dust removal apparatus 60.
Next, a configuration of the energy recycling system 100 will be described in more detail with reference to

Indoor cooling 107-2 may be performed by the absorption type cooling apparatus 107-1, and power generation 109-2 may be performed by the stirling power generator 109-1.
Next, structures of the energy recovery apparatus (a heat pipe) 31, the inertial impact type dust removal apparatus 33, the inertial impact type energy recovery and dust removal assembly 35, and the chamber included in the energy recovery and inertial impact type dust removal unit 30 are used in the energy recycling type dust removing processing system for removing a contaminated material from high temperature contaminated gas and will be described in more detail with reference to
The energy recovery and inertial impact type dust removal unit in which the heat pipe shown in
As shown in
The first inertial impact apparatus 33-1 serves to remove the coarse dust in the high temperature exhaust gas that is collected in and introduced from the collecting duct 20 at the front end by an inertial impact phenomenon.
The temperature of the plurality of heat pipes 31 increases due to the heat of the high temperature exhaust gas, as described above with reference to
Meanwhile, the second inertial impact apparatus 33-2, which has the same form as the first inertial impact apparatus 33-1, is installed at the rear end of the plurality of heat pipes 31 to remove the coarse dust once again, thereby making it possible to increase a dust removal rate.
In addition, as shown in
Next, the energy recovery and inertial impact type dust removal unit using the inertial impact type energy recovery and dust removal assembly 35, which is used in the energy recycling type dust removing processing system for removing a contaminated material in high temperature contaminated gas according to the exemplary embodiment of the present document, will be described in detail with reference to
As shown in
Meanwhile, a pair of first blocking blades 35-3 is installed at the connection point between the first and second blades 35-1 and 35-2. The dust impacts the pair of first blocking blades 35-3, such that it is removed by gravity.
In addition, a second blocking blade 35-4 is installed at a rear end portion of the second blade 35-2 to further remove dust once again.

In addition, an inertial impact phenomenon is generated in each blade of the inertial impact type energy recovery and dust removal assembly 35, such that the coarse dust included in the high temperature contaminated gas is removed.
As shown in
Meanwhile, a bottom surface of the housing 310 is provided with an adsorbent discharging unit 330. The adsorbent discharging unit 330 is an apparatus for discharging an adsorbent adsorbing exhaust gas to the zigzag channel and simultaneously generating an impact effect to coarsen fine dust. As the adsorbent, activated carbon or zeolite may be used. When this adsorbent is introduced into the zigzag channel formed by the partition walls 321 and 323, it flows together with the exhaust gas along an air current of the exhaust gas in the zigzag channel and collects the contaminated material (gas and fine dust) included in the exhaust gas. When the contaminated dust becomes sufficiently heavy (that is, when the fine dust is coarsened), it falls on planes of the partition walls. The dust falling as described above descends toward the bottom surface of the housing 310 due to the gravity, and is collected in a contaminated dust receiving part 340 through an outlet 327. In addition, the contaminated dust still present on the planes of the partition walls may fall to the contaminated dust receiving part 340 through an impact apparatus 380.
Meanwhile, an inertial impact apparatus 350 having a secondary cleaning function may be configured to have three sub-filters. The fine dust of the primarily cleaned air is removed through the inertial impact apparatus 350, such that further cleaned air may be discharged to the second duct 313.
In addition, the chamber 300 may further include an inducing fan 360 that is installed to direct a portion of an air current discharged from the second duct 313 to the adsorbent discharging unit 330. Therefore, the adsorbent may be easily introduced into the zigzag channel.

Next, the impact apparatus will be schematically described with reference to
The chamber according to the exemplary embodiment of the present document includes the impact apparatus as described above, such that the contaminated dust adsorbed with the contaminated material of the exhaust gas is not present on the partition walls, but is collected downwardly. Therefore, maintenance may be easily made.
Next, a second embodiment of the chamber according to the exemplary embodiment of the present document will be described with reference to
According to a configuration of the second embodiment of the chamber 300, the contaminated dust is not collected on the planes of the partition walls.
According to the exemplary embodiment of the present document having the above-mentioned configuration, the dust, which is a particulate air contaminated material in high temperature exhaust gas such as exhaust gas of a kiln for charcoal production and a charcoal kiln for fomentation, exhaust gas of a meat roasting restaurant, oil vapor generated in a drying process of a food processing factory, or the like, may be cleaned, and energy is recovered and recycled from the high temperature exhaust gas, thereby making it possible to improve energy efficiency.
In addition, according to the exemplary embodiment of the present document, coarse dust such as oil droplets, or the like, is first removed through the inertial impact type dust removal apparatus, such that there is an advantage in view of maintenance in that a dust collecting load of a subsequent micro dust removal apparatus is minimized and the durability of the entire system may be increased.
Further, the channel of the chamber in the in-flight adsorption apparatus is formed in the zigzag shape to secure a residence time in which the contaminated material may be adsorbed to the adsorbent, thereby making it possible to improve the efficiency of removing particulate matter and gaseous air contaminated materials.
According to the energy recycling type dust removing processing system for removing a contaminated material in high temperature contaminated gas and the inertial impact type energy recovery and dust removal apparatus as described, the configuration and the method of the exemplary embodiments described above are not restrictively applied, but all or some of the respective exemplary embodiments may be combined with each other so that the exemplary embodiments may be various modified.
