Description

Technical Field

[0001] The invention relates to a waste treatment device, and in particular to a waste treatment device with a smaller volume. Background Art

[0002] The common method of treating garbage, agricultural waste, medical waste and industrial waste is to put the waste into a treatment equipment for combustion. However, after the waste or biomass waste containing tar is carbonized, the tar will float out with the gas produced by carbonization and cause pollution. Even if the gas after the waste carbonization is controlled in the treatment equipment, the tar will clog the valves, pipes and devices in the treatment equipment and cause corrosion.

[0003] The applicant's previous Chinese patent application No. 202110119564.7 discloses a "waste treatment furnace and treatment equipment having the waste treatment furnace", comprising: a waste treatment furnace; a heat exchange system having a first heat exchange module connected to the exhaust pipe of the furnace body; a liquid storage member connected to the first heat exchange module; and a purification module having an air inlet and an exhaust port, the air inlet being connected to the first heat exchange module, and a spraying area between the air inlet and the exhaust port. The waste treatment equipment mainly uses several heat exchange systems to significantly cool the gas discharged from the waste treatment furnace, and then sends it to the purification module to remove harmful substances in the gas, and discharges pollution-free synthetic combustible gas containing carbon monoxide, hydrogen, and methane.

[0004] The waste treatment equipment disclosed in the above patent case can heat up the activated carbon slag layer of the waste treatment furnace by irradiating the microwave of the microwave emission module, and use the high temperature emitted by the activated carbon slag layer to perform a thermochemical reaction on the waste, so that the molecular structure of the organic matter is completely cracked. The gas generated by the pyrolysis of the waste can then pass through the activated carbon slag layer to filter the gas, which can prevent the harmful substances in the gas from damaging the waste treatment furnace and extend the service life of the waste treatment furnace. In addition, the gas discharged from the waste treatment furnace is greatly cooled by the heat exchange system, and can be sent to the purification module to remove the harmful substances in the gas, and discharge pollution-free synthetic combustible gas containing carbon monoxide, hydrogen, and methane for use, so as to increase the added value of the waste. However, the waste treatment equipment is bulky, and for those who only need to treat a small amount of waste, it is obviously not economical and takes up a lot of space.

[0005] In view of this, the known waste treatment equipment still needs to be improved. Summary of the invention

[0012] The present invention provides a waste treatment device, comprising: a furnace body, having a accommodating cylinder for accommodating waste, the accommodating cylinder is connected to a treatment space of the furnace body through an opening, the treatment space is formed into a pile area, a waiting area, an oxidation area, an activated carbon slag layer area and an ash accumulation area in sequence from top to bottom, the furnace body has a hollow shaft, the first end of the shaft protrudes from the top of the furnace body and is driven to rotate by a power element, the second end of the shaft extends into the treatment space, so that gas can be input from the first end and output toward the second end, the shaft itself has a plurality of blades, the activated carbon slag layer area has an exhaust gas collecting component, the exhaust gas collecting component is equipped with a purification plate, a partition and an exhaust gas pipe, the ash accumulation area has a stirring member driven to rotate by a power element, the stirring member has a plurality of blades, and the ash accumulation area has a An ash discharge port, the outer surface of the furnace body has a plurality of microwave emission modules for irradiating the activated carbon slag layer area and the ash accumulation area with microwaves to increase the temperature; a gas supply system, which is located on the outside of the furnace body, supplies gas to the plurality of microwave emission modules from a supply source, and the gas passes through the plurality of microwave emission modules and then passes through a gas exchanger to increase the gas temperature, and the gas with the increased temperature passes through a first valve and / or a second valve to be sent to the oxidation zone in the furnace body; and a liquid cooling system, which is located on the outside of the furnace body, supplies liquid to the plurality of microwave emission modules, and the liquid passes through the plurality of microwave emission modules and then passes through a gas-liquid separator to cool the purified gas for gas-liquid separation, and the condensed by-product liquid falls into a processing space and is recovered by a collection unit; the separated gas is discharged or recycled.

[0013] Accordingly, the waste treatment equipment of the present invention has only a small volume due to the change in the process and the use of an unprecedented device, and can be used to treat medium and small amounts of waste, agricultural waste, etc., and the activated carbon slag layer area is heated by the microwave irradiation of the microwave emission module, and the high temperature emitted by the activated carbon slag layer area is used to perform a thermochemical reaction on the waste, so that the molecular structure of the organic matter is completely cracked. The gas generated after the pyrolysis of the waste can then pass through the activated carbon slag layer area to filter the gas, and undergo a complex chemical reaction with the elements generated by the cracking of the activated carbon slag layer area. The gas can then pass through the waste gas collecting component to contact the catalyst on the purification plate, so that the gas undergoes a chemical reaction and is purified, and the by-products such as tar or wood vinegar in the gas are condensed and recovered through the gas-liquid separator, so that harmful substances in the gas can be prevented from damaging the waste treatment equipment, and the service life of the waste treatment furnace can be extended.

[0015] The gas supply system includes a first blower, which is located at the front end or the rear end of the gas exchanger. Thus, the first blower can help the flow and pressurization of the gas.

[0016] The gas passing through the gas exchanger is controlled by a fifth gas channel and a first valve to be sent into the oxidation zone in the furnace body, so that the waste in the oxidation zone can be preheated and the oxygen content can be increased to achieve the effect of supporting combustion.

[0017] The gas passing through the gas exchanger is controlled by a sixth gas passage connected to the fifth gas passage through a second valve, so that the gas is input from the first end of the shaft of the furnace body through the sixth gas passage.

[0018] The first valve and the second valve are opened when one is closed or both are opened at the same time. Thus, the gas can be sent into the oxidation zone in the furnace body through the fifth gas channel or / and the second end of the shaft, so that the waste can be preheated and the oxygen content can be increased and the waste can be rapidly thermally cracked to form carbonized particles and ash.

[0019] The gas purified by the exhaust gas collecting element in the furnace body is introduced into a pipeline of the gas exchanger through the exhaust gas pipe, so that the purified gas can be cooled.

[0021] The liquid cooling system includes a second blower, which is located at the rear end of the collecting unit to help the flow and pressurization of the gas. Thus, the second blower can help the flow and pressurization of the gas.

[0022] The gas-liquid separator has a pressure relief valve. Thus, when the second blower is abnormal or the eighth air passage is blocked and the gas-liquid separator cannot discharge the high-temperature exhaust gas normally, the high-temperature exhaust gas in the furnace body can be automatically discharged through the pressure relief valve, thereby avoiding damage to the furnace body or explosion, fire, etc. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the preferred embodiments of the present invention are listed below and described in detail with reference to the accompanying drawings; in addition, the same symbols in different drawings are regarded as the same and their descriptions are omitted.

[0029] Please refer to Figure 1 As shown, it is a preferred embodiment of the waste treatment equipment of the present invention, comprising a furnace body 1, a gas supply system 2 and a liquid cooling system 3. The gas supply system 2 provides combustion-supporting gas to the furnace body 1, and the liquid cooling system 3 provides cooling for the furnace body 1.

[0030] Please refer to Figure 2 , Figure 3 As shown, it is a preferred embodiment of the furnace body 1 of the present invention. The top of the furnace body 1 is provided with a accommodating cylinder 11, and the accommodating cylinder 11 is used to accommodate waste. The accommodating cylinder 11 is connected to a processing space S of the furnace body 1 through an opening 12, so that the waste accommodated in the accommodating cylinder 11 can fall into the processing space S through the opening 12. The opening 12 can be controlled by a first valve plate 121 and an actuating cylinder 122, so that the first valve plate 121 can open and close the opening 12 to control whether the waste falls into the processing space S. The processing space S forms a pile area S1, a waiting area S2, an oxidation area S3, an activated carbon slag layer area S4 and an ash accumulation area S5 from top to bottom. There is no need to limit the size of the range between the areas, which is only used for subsequent related explanations.

[0031] The furnace body 1 has a shaft 13, and the first end 131 of the shaft 13 protrudes from the top of the furnace body 1. The first end 131 can be driven to rotate by a power element 14. The second end 132 of the shaft 13 extends into the processing space S. Preferably, the second end 132 extends into the oxidation zone S3. The shaft 13 has a hollow fluid channel 133, so that gas can be input from the first end 131 of the shaft 13, and the gas is output toward the second end 132 through the fluid channel 133. Preferably, the second end 132 can have a plurality of shunt pipes 134 in a radial shape, so that the gas can be output toward the oxidation zone S3 through the plurality of shunt pipes 134.

[0032] The shaft 13 itself has a plurality of blades 15, which may include an upper blade 151, at least one middle blade 152 and a lower blade 153 in sequence from the first end 131 to the second end 132. When the shaft 13 rotates, the upper blade 151 may break up and flatten the waste in the stockpiling area S1, the at least one middle blade 152 may break up the waste in the waiting area S2 and prevent bridging, and the lower blade 153 may lift and move the waste in the oxidation area S3, and cooperate with the air output by the plurality of shunt pipes 134 to increase the oxygen content of the waste. Furthermore, the plurality of radial shunt pipes 134 may also have the function of lifting and moving the waste, and cooperate with the air output by the plurality of shunt pipes 134 to increase the oxygen content of the waste.

[0033] The activated carbon slag layer area S4 has an exhaust gas collection part 16, and the exhaust gas collection part 16 has a purification plate 161, a partition 162 and an exhaust pipe 163 built therein. The purification plates 161 are staggered and are metal plates carrying a catalyst selected from nickel catalyst, titanium catalyst, platinum catalyst, palladium catalyst, rhodium catalyst, etc., so that the gas passing through the purification plate 161 contacts the catalyst on the surface of the purification plate 161 to undergo a chemical reaction and be purified, which can improve the purification efficiency. The purified gas rises through the partition 162 and is discharged from the exhaust pipe 163 (to be described in detail later).

[0034] The ash accumulation area S5 is located at the bottom of the furnace body 1. The ash accumulation area S5 has a stirring member 17. The stirring member 17 has a plurality of blades 171. The plurality of blades 171 can be driven to rotate by a power element 172. The plurality of blades 171 are used to stir the carbonized particles and ash falling into the ash accumulation area S5 and can be discharged to the outside of the furnace body 1 through an ash outlet O of the ash accumulation area S5. The ash outlet O can have a second valve plate 18. The second valve plate 18 can be controlled by an actuator C so that the second valve plate 18 can open and close the ash outlet O to control whether the carbonized particles and ash fall outside the furnace body 1.

[0035] The outer surface of the furnace body 1 is provided with a plurality of microwave transmitting modules 19, and the plurality of microwave transmitting modules 19 can surround the furnace body 1. The plurality of microwave transmitting modules 19 can irradiate the activated carbon slag layer area S4 and the ash accumulation area S5 with microwaves to increase the temperature, so as to perform a thermochemical reaction on the waste with the high temperature emitted by the activated carbon slag layer area S4, so as to completely crack the molecular structure of the organic matter. The gas generated after the pyrolysis of the waste can then pass through the activated carbon slag layer area S4 to filter the gas, and to perform a complex chemical reaction with the elements generated by the cracking of the activated carbon slag layer area S4.

[0036] Please refer to Figure 1As shown, the gas supply system 2 is located outside the furnace body 1. The gas supply system 2 is a gas supply source 21 that supplies gas to the plurality of microwave emission modules 19 so that the plurality of microwave emission modules 19 can be cooled. After passing through the plurality of microwave emission modules 19, the gas can enter a gas exchanger 25 through an air inlet 25a to increase the gas temperature (described in detail later). The bottom of the gas exchanger 25 can have a maintenance hole 251 to facilitate maintenance of the gas exchanger 25. The gas with increased temperature is then selectively sent to the oxidation zone S3 in the furnace body 1 through a gas outlet 25b, a first valve V1 and / or a second valve V2 to heat the waste in the furnace body 1, preheat the waste, increase the oxygen content and assist combustion. Preferably, the gas supply system 2 includes a first blower (BLOW) 24, which can help the flow and pressurization of the gas. The first blower 24 can be located at the front end or the rear end of the gas exchanger 25, which is not limited by the present invention.

[0037] Specifically, the supply source 21 may include an air filter to supply clean low-temperature air to a lower annular air pipe 22 via a first air channel a1, and the lower annular air pipe 22 is introduced into the plurality of microwave emission modules 19 via a plurality of second air channels a2 to cool the plurality of microwave emission modules 19. The plurality of microwave emission modules 19 are each connected to an upper annular air pipe 23 via a third air channel a3, and the upper annular air pipe 23 is further connected to the air inlet 25a of the gas exchanger 25 via a fourth air channel a4. Preferably, the air supply system 2 includes a first blower 24, and the first blower 24 is connected to the fourth air channel a4 and the air inlet 25a of the gas exchanger 25. The gas exchanger 2 The waste gas collecting element 16 has a pipeline 25c connected to the waste gas pipe 163, so that the low-temperature gas entering the gas exchanger 25 can exchange heat with the high-temperature gas passing through the pipeline 25c. The gas heated by the gas exchanger 25 is controlled by a fifth gas channel a5 and a first valve V1 to send the gas to the oxidation zone S3 in the furnace body 1; or, the gas is controlled by a second valve V2 through a sixth gas channel a6 connected to the fifth gas channel a5 to be input from the first end 131 of the shaft 13 of the furnace body 1 through a sixth gas channel a6, and the gas can be output toward the second end 132 through the fluid channel 133, so that the waste is preheated and the oxygen content is increased. Preferably, the first valve V1 and the second valve V2 are closed when one is opened. Of course, the first valve V1 and the second valve V2 can also be opened at the same time, so that the gas can be simultaneously input from the fifth gas channel a5 and the sixth gas channel a6 to the oxidation zone S3 in the furnace body 1 to preheat the waste, increase the oxygen content and assist combustion. The present invention is not limited to this.

[0038] In addition, if Figure 3As shown, after the high-temperature exhaust gas purified by the exhaust gas collecting element 16 in the furnace body 1 is discharged through the exhaust gas pipe 163, the exhaust gas pipe 163 can be connected to the pipeline 25c to introduce the purified high-temperature exhaust gas into the gas exchanger 25 (such as Figure 1 As shown), the purified high-temperature exhaust gas in the pipeline 25c is heat-exchanged with the low-temperature gas supplied from the air inlet 25a. After the first cooling, the purified high-temperature exhaust gas in the pipeline 25c can be input into a gas-liquid separator 33 through a seventh air channel a7.

[0039] Please refer to Figure 1 , Figure 3 As shown, the liquid cooling system 3 is located outside the furnace body 1. The liquid cooling system 3 can supply liquid to the plurality of microwave transmitting modules 19 so that the plurality of microwave transmitting modules 19 can be cooled. The liquid can enter the gas-liquid separator 33 after passing through the plurality of microwave transmitting modules 19 to cool the purified high-temperature exhaust gas and perform gas-liquid separation. The purified high-temperature exhaust gas can be condensed into by-product liquids such as tar or wood vinegar after cooling and fall into a processing space 331, and these by-product liquids can be recovered by a collection unit 332; the separated gas can be discharged or reused through a hollow eighth air channel a8. Preferably, the eighth air channel a8 is connected to a second blower 35 to help the gas flow and pressurization. The second blower 35 can be located at the rear end of the collection unit 332 to help the gas flow and pressurization. Preferably, the gas-liquid separator 33 has a pressure relief valve 333, so when the second blower 35 is abnormal or when the eighth airway a8 is blocked and the gas-liquid separator 33 cannot normally discharge the high-temperature exhaust gas, the high-temperature exhaust gas in the furnace body 1 can be automatically discharged through the pressure relief valve 333 to avoid damage to the furnace body 1 or explosion, fire and the like.

[0040] Specifically, the liquid cooling system 3 is located on the outside of the furnace body 1. The liquid cooling system 3 has a liquid storage tank 31 for storing liquid. The water pump 32 can extract the stored liquid through a first pipe P1. The first pipe P1 can have a third valve V3 and a one-way valve 36. The first pipe P1 is connected to a lower annular liquid pipe 37. The lower annular liquid pipe 37 introduces the liquid into the plurality of microwave transmitting modules 19 through a plurality of second pipes P2 to cool the plurality of microwave transmitting modules 19. The plurality of microwave transmitting modules 19 are each connected to an upper annular liquid pipe 38 through a third pipe P3. The upper annular liquid pipe 38 is further connected to the pipe inside the gas-liquid separator 33 through a fourth pipe P4, so that the high-temperature exhaust gas input from the seventh gas channel a7 into the gas-liquid separator 33 can be cooled and separated into gas and liquid. The gas-liquid separator 33 has a processing space 331, and the condensed byproduct liquid such as tar or wood vinegar falls into the processing space 331 and can be recovered by the collection unit 332. The pollution-free gas that meets the environmental protection standard passing through the collection unit 332 can be discharged or recovered through the eighth air channel a8 due to the suction effect of the second blower 35, including carbon monoxide (CO), hydrogen (H), methane (CH 4 ) and other useful synthetic gases for use, the eighth gas passage a8 can be connected to a second blower 35, and the second blower 35 helps the flow and pressurization of the gas. In addition, the liquid flowing through the gas-liquid separator 33 can be discharged through a fifth pipe P5, a sixth pipe P6 and a fourth valve V4; or, the liquid can be guided to a radiator 34 through a fifth valve V5 and a seventh pipe P7, so that the liquid can be guided back to the liquid storage tank 31 through an eighth pipe P8 after passing through the radiator 34 for recycling. Preferably, the fourth valve V4 and the fifth valve V5 are closed when one is opened.

[0041] The common method of making "activated carbon" is basically divided into two processes. The first process includes dehydration and carbonization. The raw material is heated at a temperature of 170 to 600°C to dry and carbonize about 80% of the original organic matter. The second process is to use chemical or physical methods (the activated carbon raw material formed into an appropriate shape of organic waste is placed in a heating furnace, the temperature is set and the pressure is set in the furnace for activation. Under the condition of passing gas, microwaves or high frequencies are applied to the activated carbon raw material, and the activated carbon raw material is heated internally to carbonize and activate it. One of the physical methods of carbide activation is to react with activators such as water vapor and charcoal.

[0042] Please refer to Figure 2 , Figure 3As shown, when the furnace body 1 of the present invention is used for the first time, waste (including rice husks, wood, coconut shells, sawdust, coal, coke, peat, lignin, fruit cores, nut shells, sucrose pulp, bones, lignite, petroleum residues, etc.) is first accumulated in the activated carbon slag layer area S4 and the ash accumulation area S5, the opening 12 is closed to make the processing space S in an oxygen-free or very low oxygen condition, and the plurality of microwave transmitting modules 19 are turned on to irradiate microwaves. When the waste in the activated carbon slag layer area S4 and the ash accumulation area S5 is irradiated by the microwaves and the temperature rises to 500-1250°C, a combustion process can be performed to form the activated carbon slag layer area S4 and the ash accumulation area S5.

[0043] In summary, the waste treatment equipment of the present invention has only a small volume due to the change of the process and the use of an unprecedented device. It can be used to treat medium and small amounts of waste, agricultural waste, etc., and the activated carbon slag layer area is heated by the microwave irradiation of the microwave emission module, and the high temperature emitted by the activated carbon slag layer area is used to perform a thermochemical reaction on the waste, so that the molecular structure of the organic matter is completely cracked. The high-temperature exhaust gas generated after the pyrolysis of the waste can continue to pass through the activated carbon slag layer area to filter the high-temperature exhaust gas, and perform a complex chemical reaction with the elements generated by the cracking of the activated carbon slag layer area. The high-temperature exhaust gas can then pass through the exhaust gas collecting component to contact the catalyst on the purification plate, so that the high-temperature exhaust gas undergoes a chemical reaction and is purified. In addition, the by-products such as tar or wood vinegar in the high-temperature exhaust gas are condensed and recovered through the gas-liquid separator, so that harmful substances in the high-temperature exhaust gas can be prevented from damaging the waste treatment equipment, and the service life of the waste treatment furnace can be extended. In addition, the waste treatment equipment of the present invention can reduce the temperature of the high-temperature exhaust gas by means of the gas exchanger and the gas-liquid separator, and can remove harmful substances in the high-temperature exhaust gas, thereby discharging pollution-free gas that meets environmental protection standards and recovering gas containing carbon monoxide (CO), hydrogen (H2), methane (CH 4 ) and other useful synthetic gases can be used to improve the pyrolysis efficiency of waste, thereby increasing the added value of waste.
