The present invention relates to a recycling system, in particular to a recycling system capable of introducing outside air into the recycling system for a smoldering combustion of a combustible waste material (such as a waste wood, fabric or plastic material) filled into the recycling system, such that the outside air can be distributed around every cross-section in the recycling system and moved together with a high-temperature dense smoke produced in the smoldering combustion to fully incinerate the waste material, and recycle or reuse a gas (such as carbon monoxide and hydrogen gas) containing combustible energy (produced by an incomplete combustion of the waste materials) in the dense smoke to achieve the effects of energy regeneration, recycle and reuse.
At present, a waste material (such as a waste wood, fabric or plastic material) that cannot be recycled directly is generally processed by the following two methods:
Since the landfill method requires a large landfill site for burying the waste materials, and some countries have small area and dense population and not much land reserved for burying the waste materials continuously. Furthermore, the landfill method creates an odor problem after the waste materials are buried in soils and gradually decayed or decomposed by microorganisms, and a liquid leachate containing microorganisms and germs is produced and permeated into the soil, which contaminates underground water sources and creates crises to our environmental hygiene and ecological condition, or even affects the health of residents nearby. In recent years, governments have started promoting a “zero landfill” policy as the awareness of the environmental protection rises, and adopted the incineration method as a major method for disposing waste materials.
According to related research data, the traditional incinerators presently used for carrying out the incineration method still have the following drawbacks:
Therefore, it is an important subject of the present invention to design an innovative combustible energy recycling system and a method thereof to overcome the shortcomings of the traditional incinerators that cause an air pollution by the combusted waste materials, and enhance the combustion efficiency of the incinerator and recycle and reuse the gas containing combustible energy in the dense smoke when the incinerator adopts the smoldering combustion method for processing the waste materials.
In view of the shortcomings of the prior art, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a combustible energy recycling system and its method to overcome the poor combustion efficiency, air pollution, and difficulty of recycling and reusing a gas (such as carbon monoxide and hydrogen gas produced by an incomplete combustion of waste materials) containing combustible energy in the dense smoke produced by the conventional incinerator.
Therefore, it is a primary objective of the present invention to provide a combustible energy recycling system, comprising an airtight incinerator body and a blower, wherein the incinerator body includes a first gate that can be opened and closed, such that an operator can open the first gate to fill a combustible waste material (such as a waste wood, fabric or plastic material, etc) into the incinerator body, and the blower includes an air outlet pipe, and an end of the air outlet pipe is passed into the incinerator body. The recycling system further comprises a gas intake module installed in the incinerator body and interconnected with the air outlet pipe, and the gas intake module includes a plurality of gas intake pipes, and one of the gas intake pipes is an ignition pipe provided for the operator to ignite the waste materials in the incinerator body through the ignition pipe and allow the waste materials to be smoldered in the incinerator body. The blower introduces outside air into the incinerator body through the gas intake module, and the outside air produces an air whirl flowing with respect to the center of the incinerator inside the incinerator body and surrounding every cross-section inside the incinerator body. The high-temperature dense smoke produced by the smoldering combustion of the waste materials climbs upward, so that the waste materials in the incinerator body can be smoldered uniformly, and the dense smoke produced by the smoldering combustion and the gas containing combustible energy are discharged to a gas recycling mechanism or a burning mechanism for its recycle and reuse. Since the recycling system of the present invention can smolder all waste materials in the incinerator body through the air whirl produced by the outside air to improve the combustion efficiency of the recycling system, and the gas containing combustible energy produced by the smoldering combustion of the waste material in the recycling system can be recycled and reused completely to prevent the dusts and impurities from flying or drifting to the outside, therefore the green environmental protection requirements for energy recycle and reuse, energy saving, and carbon reduction can be met, and the air pollution issue created by the smoldering combustion of the waste materials can be avoided.
Another objective of the present invention is to provide a combustible energy recycling system, wherein the incinerator body includes a water storage tank installed at an internal periphery of the incinerator body and interconnected to a water pipe, for storing liquid coming from the water pipe, and the water storage tank includes at least one ventilation hole formed at a position proximate to the top of the incinerator body, such that when the liquid in the water storage tank is heated and evaporated into steam, the steam can be entered into the interior of the incinerator body through each ventilation hole, and condensed into water drops inside the incinerator body, and the water drops are dropped onto the waste material. As a result, when the interior of the incinerator body has a too-low humidity and a too fiercely burning flame, the water drops dropped on the waste materials can slow down the too-fiercely burning flame and lower the temperature inside the incinerator body when the waste materials are combusted.
Another objective of the present invention is to provide a combustible energy recycling system, wherein the smoke exhaust pipe is installed at a pipe mouth at an end of the incinerator body and towards the bottom of the recycling system, and the recycling system includes a first filter unit in a shape of a tank disposed at a position proximate to an end of the smoke exhaust pipe for containing a liquid, and the level of the liquid is proximate to the pipe mouth of the smoke exhaust pipe, such that when an air pressure produced inside the incinerator body is greater than a predetermined multiple of the outside air pressure, then the dense smoke containing dusts and impurities will be forced to be discharged to the outside through the smoke exhaust pipe. Now, the dusts and impurities having a larger volume and a heavier weight will fall into the liquid, so that the first filter unit can be used for improving the purity of the gas containing combustible energy discharged from the recycling system.
Another objective of the present invention is to provide a method of using the aforementioned recycling system to recycle a gas containing the combustible energy in an incineration of waste materials, so that manufacturers can use the recycling system to increase the combustion efficiency, avoid an air pollution issue caused by a smoldering combustion, and recycle a highly pure gas containing combustible energy effectively to achieve an energy recycling effect.
After a waste material (such as a waste wood, fabric or plastic material) goes through a smoldering combustion, a large amount of carbon dioxide (CO2) and carbon (C) is produced, and water (H2O) contained in the waste material will be heated and evaporated into steam. When the carbon dioxide and carbon produce an endothermic reaction, then carbon monoxide (CO) gas containing combustible energy will be produced. When steam and carbon produce an endothermic reaction, carbon monoxide and hydrogen gas (H2) containing combustible energy will be produced. Thus, the inventor of the present invention based on this principle to design and test repeatedly, and finally developed a combustible energy recycling system and its method in accordance with the present invention to increase the production of gas containing combustible energy when the waste materials are incinerated or smoldered.
With reference to
When an operator uses the recycling system 1 for the smoldering combustion of the waste material, outside air is introduced into the incinerator body 10 through the openings 111 of each gas intake pipe 110. An air whirl is formed uniformly at the bottom position of the incinerator body 10 and flows in circumferential directions of different radii with respect to the center of the incinerator, and the blower 12 produces an air pressure inside the incinerator body 10 which is greater than a predetermined multiple of the outside air pressure, such that the outside air can rise slowly upward together with a high-temperature dense smoke produced in the smoldering combustion of the waste material and uniformly surround every cross-section in the incinerator body 10, and the waste material at every cross-section of the incinerator body 10 can be smoldered evenly from the bottom to the top at a predetermined air pressure, as well as the appropriate combustion temperature and humidity in the incinerator body 10. Therefore, the dense smoke and a gas such as carbon monoxide and hydrogen gas containing combustible energy (produced by an incomplete combustion of the waste materials) can be guided from a smoke exhaust pipe 101 of the incinerator body 10 to a gas recycling mechanism 2 or a burning mechanism 2 for recycling or reusing the gas containing the combustible energy.
Since the recycling system 1 of the present invention can introduce outside air uniformly through the blower 12 and the gas intake module 11 for an uniform smoldering combustion of the waste material in every cross-section of the incinerator body 10 to fully smolder all waste materials in the incinerator body 10, so as to achieve the effect of improving the combustion efficiency of the recycling system 1. While the waste material is being incinerated, the recycling system 1 can recycle or reuse the gas containing combustible energy produced in the smoldering combustion, and thus the invention can avoid the air pollution issue created by the flying or drifting of dusts and impurities in the dense smoke to the outside, so as to achieve the effects of energy recycle and reuse and meet the green environmental protection requirements for energy saving and carbon reduction.
