Description

Waste treatment equipment

The present invention relates to a waste treatment device, and in particular to a waste treatment device of a smaller size.

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 containing tar or biomass waste is carbonized, the tar will be emitted with the gas generated by carbonization to cause pollution. Even if the gas after the waste is carbonized is controlled in the treatment equipment, the tar will clog the valves, pipes and devices in the treatment equipment and cause corrosion.

The applicant's previous application for the Republic of China patent publication No. TWI785445B 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 air exhaust port, the air inlet being connected to the first heat exchange module, and a spraying area being provided between the air inlet and the air 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 gas containing carbon monoxide and hydrogen.

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 from the microwave emitting 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 organic matter is completely cracked. The gas generated by the pyrolysis of the waste can continue to pass through the activated carbon slag layer to filter the gas, thereby preventing harmful substances in the gas from damaging the waste treatment furnace and extending the service life of the waste treatment furnace. Furthermore, the heat exchange system can significantly cool the gas discharged from the waste treatment furnace, and can be sent to the purification module to remove harmful substances in the gas, and discharge pollution-free synthetic gas containing carbon monoxide and hydrogen for utilization, so as to increase the added value of the waste. However, the waste treatment equipment is large in size, which is obviously not economical for those who only need to treat a small amount of waste and takes up a lot of space.

In view of this, the conventional waste treatment equipment still needs to be improved.

In order to solve the above problems, the purpose of the present invention is to provide a waste treatment equipment which has only a relatively small volume and is used to treat medium and small amounts of waste.

The second purpose of the present invention is to provide a waste treatment device that can recycle the by-products generated by burning the waste to prevent the harmful substances in the gas from causing damage to the waste treatment furnace.

Another object of the present invention is to provide a waste treatment device that can remove harmful substances from the gas generated by burning the waste to discharge pollution-free gas that meets environmental protection standards.

The waste treatment equipment of the present invention comprises: a furnace body, a containing tube for containing waste, the containing tube is connected to a processing space of the furnace body through an opening, the processing space is formed from top to bottom in sequence as a material stacking area, a material waiting area, an oxidation area, an activated carbon slag layer area and an ash slag stacking area, the furnace body has a hollow shaft, the first end of the shaft protrudes from the top of the furnace body and is driven by a power element The second end of the shaft extends into the processing space so that gas can be input from the first end and output toward the second end. The shaft itself has a number of blades. The activated carbon slag layer area has a waste gas collection piece. The waste gas collection piece has a purification plate, a partition and a waste gas pipe. The ash accumulation area has a power element that drives a stirring piece to rotate. The stirring piece has a number of blades, and the ash accumulation area has An ash outlet is provided, and the outer surface of the furnace body is provided with a plurality of microwave emission modules for irradiating the activated carbon slag layer area and the ash slag accumulation area with microwaves to increase the temperature; a gas supply system is located on the outer side of the furnace body, and a gas supply source supplies gas to the plurality of microwave emission modules, 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 The second valve is used to send the gas into the oxidation zone in the furnace; and a liquid cooling system is located on the outside of the furnace to supply liquid to the microwave emission modules. After passing through the microwave emission modules, the liquid is cooled by a gas-liquid separator and the purified gas is separated into gas and liquid. The condensed byproduct liquid falls into a processing space and is recovered by a collection unit; the separated gas is discharged or recycled.

Accordingly, the waste treatment equipment of the present invention has only a relatively small volume due to the change of 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 is heated by the microwave irradiation of the microwave emitting module, and the high temperature emitted by the activated carbon slag layer is used to perform a thermochemical reaction on the waste, so that the molecular structure of the organic matter is completely cracked, and the gas generated by the pyrolysis of the waste can continue to pass through the activated carbon slag layer to The gas is filtered and undergoes a complex chemical reaction with the elements generated by the cracking of the activated carbon slag layer. The gas can then contact the catalyst on the purification plate through the waste gas collector so that the gas undergoes a chemical reaction and is purified. In addition, by-products such as tar or wood vinegar in the gas are condensed and recovered through the gas-liquid separator, thereby preventing harmful substances in the gas from damaging the waste treatment equipment and achieving the effect of extending the service life of the waste treatment furnace. In addition, the waste treatment equipment of the present invention can reduce the temperature of the gas through the gas exchanger and remove harmful substances in the gas, thereby discharging pollution-free gas that meets environmental protection standards and recovering useful synthetic gas containing carbon monoxide (CO), hydrogen (H), methane (CH4), etc. for use, so as to improve the pyrolysis efficiency of the waste, thereby achieving the effect of increasing the added value of the waste.

In this way, the waste in the oxidation zone can be preheated and the oxygen content can be increased to achieve the effect of supporting combustion.

The gas passing through the gas exchanger is controlled by a sixth gas passage connected to the fifth gas passage through the second valve, so that the gas is input from the first end of the shaft of the furnace body through the sixth gas passage. In this way, the gas can be input from the first end of the shaft and output toward the second end to the oxidation zone in the furnace body through the fluid channel, so that the waste can be preheated and the oxygen content can be increased and thermally cracked quickly to form carbonized particles and ash.

Among them, the first valve and the second valve are opened when one is closed or both are opened at the same time. In this way, 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 thermally cracked quickly to form carbonized particles and ash.

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. In this way, the purified gas can be cooled.

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. In this way, the second blower can help the flow and pressurization of the gas.

The gas-liquid separator has a pressure relief valve. Thus, when the second blower is abnormal or the eighth airway 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 relief valve, which can avoid damage to the furnace body or explosion, fire, etc.

In order to make the above and other purposes, features and advantages of the present invention more clearly understood, the following specifically cites the preferred embodiments of the present invention and provides a detailed description in conjunction with the attached drawings; in addition, the same symbols in different drawings are considered the same and their descriptions will be omitted.

Please refer to FIG. 1, which is a preferred embodiment of the waste treatment equipment of the present invention, comprising a furnace body 1, an air supply system 2 and a liquid cooling system 3. The air supply system 2 provides combustion-supporting gas to the furnace body 1, and the liquid cooling system 3 provides cooling to the furnace body 1.

Please refer to Figures 2 and 3, which are a preferred embodiment of the furnace body 1 of the present invention. The top of the furnace body 1 has a container 11, which is used to contain waste. The container 11 is connected to a processing space S of the furnace body 1 through an opening 12, so that the waste contained in the container 11 can fall into the processing space S through the opening 12. The opening 12 can be opened by a first valve disc 121. Controlled by an actuator 122, the first valve disc 121 can open and close the opening 12 to control whether the waste falls into the processing space S. The processing space S sequentially forms a material stacking area S1, a material waiting area S2, an oxidation area S3, an activated carbon slag layer area S4 and an ash slag accumulation area S5 from top to bottom. There is no need to limit the size of each area, which is only used for subsequent related explanations.

The furnace body 1 has a shaft 13, 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 the 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 be radiated with multiple shunt pipes 134, so that the gas can be output toward the oxidation zone S3 through the multiple shunt pipes 134.

The shaft 13 itself has a number of blades 15, which can 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 can break up and level the waste in the stacking area S1, the at least one middle blade 152 can break up the waste in the waiting area S2 and prevent bridging, and the lower blade 153 can lift and stir the waste in the oxidation area S3, and cooperate with the air output by the multiple shunt pipes 134 to increase the oxygen content of the waste. Furthermore, the multiple radiating diversion tubes 134 can also have the function of lifting and moving the waste, so as to cooperate with the air output by the multiple diversion tubes 134 to increase the oxygen content of the waste.

The activated carbon slag layer S4 has a waste gas collection part 16, in which a purification plate 161, a partition 162 and a waste gas pipe 163 are placed. The purification plates 161 are staggered and carry metal plates selected from nickel, titanium, platinum, palladium, rhodium and other catalysts, so that the gas passing through the purification plate 161 contacts the catalyst on the surface of the purification plate 161 and undergoes a chemical reaction to be purified, which can improve the purification efficiency. The purified gas rises and passes through the partition 162 and is discharged from the waste gas pipe 163 (described later).

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 in the ash accumulation area S5 and discharge them from an ash discharge port O of the ash accumulation area S5 to the outside of the furnace body 1. The ash discharge port O can have a second valve disc 18. The second valve disc 18 can be controlled by an actuator C so that the second valve disc 18 can open and close the ash discharge port O to control whether the carbonized particles and ash fall outside the furnace body 1.

The outer surface of the furnace body 1 is provided with a plurality of microwave emission modules 19, which can surround the furnace body 1. The plurality of microwave emission modules 19 can irradiate the activated carbon slag layer area S4 and the ash slag accumulation area S5 with microwaves to increase the temperature, and the high temperature emitted by the activated carbon slag layer area S4 can be used 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 continue to pass through the activated carbon slag layer area S4 to filter the gas, and perform a complex chemical reaction with the elements generated by the cracking of the activated carbon slag layer area S4.

Please refer to FIG. 1 , the gas supply system 2 is located on the outside of the furnace body 1. The gas supply system 2 supplies gas to the microwave emission modules 19 through a supply source 21, so that the microwave emission modules 19 can be cooled. After passing through the microwave emission modules 19, the gas can enter a gas exchanger 25 through an air inlet 25a to increase the gas temperature (described later). The gas exchanger 25 can have a maintenance hole 251 at the bottom to facilitate maintenance of the gas exchanger 25. The gas with increased temperature is 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 and 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 rear end of the gas exchanger 25, which is not limited by the present invention.

In detail, the supply source 21 may include an air filter to supply clean low-temperature air to a lower annular air pipe 22 through a first air channel a1, and the lower annular air pipe 22 is introduced into the microwave emission modules 19 through a second air channel a2 to cool the microwave emission modules 19. The microwave emission modules 19 are respectively connected to an upper annular air pipe 23 through 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 through 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 25 The exhaust gas collecting device 16 has a pipeline 25c for connecting the exhaust 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 the first valve V1 to send the gas to the oxidation zone S3 in the furnace 1; or, the gas is controlled by the 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 1 through the sixth gas channel a6, and the gas can be output toward the second end 132 through the fluid channel 133 to preheat the waste and increase the oxygen content. Preferably, the first valve V1 and the second valve V2 are opened when one is closed. 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 and increase the oxygen content and assist combustion. The present invention is not limited thereto.

In addition, as shown in FIG. 3, 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 (as shown in FIG. 1), so that the purified high-temperature exhaust gas in the pipeline 25c and the low-temperature gas supplied from the air inlet 25a can perform heat exchange. After the first cooling, the purified high-temperature exhaust gas in the pipeline 25c can be input to a gas-liquid separator 33 through a seventh air channel a7.

Please refer to Figures 1 and 3. The liquid cooling system 3 is located on the outside of the furnace body 1. The liquid cooling system 3 can supply liquid to the microwave emission modules 19 so that the microwave emission modules 19 can be cooled. After passing through the microwave emission modules 19, the liquid can enter the gas-liquid separator 33 to cool the purified high-temperature exhaust gas and perform gas-liquid separation. After cooling, the purified high-temperature exhaust gas can be condensed into by-product liquids such as tar or wood vinegar and fall into a processing space 331. The by-product liquids can be recovered by a collection unit 332; the separated gas can be discharged or reused through a hollow eighth air duct a8. Preferably, the eighth air passage 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 collecting 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 air passage a8 is blocked and the gas-liquid separator 33 cannot discharge the high-temperature exhaust gas normally, the high-temperature exhaust gas in the furnace body 1 can be automatically discharged through the relief valve 333 to avoid damage to the furnace body 1 or explosion, fire, etc.

Specifically, the liquid cooling system 3 is located outside 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 check valve 36. The first pipe P1 is connected to a lower annular liquid pipe 37. The lower annular liquid pipe 37 guides the liquid to the second pipe P2. The microwave emitting modules 19 are respectively connected to an upper annular liquid pipe 38 by a third pipe P3, and the upper annular liquid pipe 38 is further connected to the pipe inside the gas-liquid separator 33 by a fourth pipe P4, so that the high-temperature exhaust gas input from the seventh air channel a7 into the gas-liquid separator 33 can be cooled and separated into gas and liquid. The gas-liquid separator 33 has the processing space 331, and the condensed by-product liquid such as tar or wood vinegar falls into the processing space 331 and can be recovered by the collecting unit 332. The pollution-free gas that meets environmental protection standards passing through the collecting unit 332 can be discharged or recovered through the eighth air duct a8 due to the suction action of the second blower 35 to form useful synthetic gas containing carbon monoxide (CO), hydrogen (H), methane (CH4), etc. for utilization. The eighth air duct a8 can be connected to a second blower 35 to help 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 led to a radiator 34 through a fifth valve V5 and a seventh pipe P7, so that the liquid can be led 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.

The common production method of "activated carbon" is basically divided into two processes. The first process includes dehydration and carbonization. The raw materials are 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 methods or physical methods (the activated carbon raw materials formed into appropriate shapes of organic waste are placed in a heating furnace, the temperature and pressure in the furnace are set for activation, and microwaves or high frequencies are applied to the activated carbon raw materials while the gas is introduced, and the activated carbon raw materials are heated internally to carbonize and activate them. One of the physical methods for carbide activation is to react with activators such as water vapor and charcoal.

Referring to FIGS. 2 and 3 , when the furnace body 1 of the present invention is used for the first time, waste materials (such as rice husks, wood, coconut shells, sawdust, coal, coke, peat, lignin, fruit cores, nut shells, sugarcane pulp, bones, lignite, petroleum residues, etc.) are first piled up in the activated carbon slag layer area S4 and the ash accumulation area S5, and the opening 1 is closed. 2. The processing space S is placed in an oxygen-free or oxygen-less state, and the microwave emission module 19 is turned on to irradiate microwaves. When the waste in the activated carbon slag layer area S4 and the ash slag accumulation area S5 is irradiated by the microwaves and the temperature rises to 500-900°C, a combustion process can be performed to form the activated carbon slag layer area S4 and the ash slag accumulation area S5.

In summary, the waste treatment equipment of the present invention has a relatively small size 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 is heated by the microwave irradiation of the microwave emitting module, and the high temperature emitted by the activated carbon slag layer 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 by the pyrolysis of the waste can continue to pass through the activated carbon slag layer to react with the high-temperature The waste gas is filtered and undergoes a complex chemical reaction with the elements generated by the cracking of the activated carbon slag layer. The high-temperature waste gas can continue to contact the catalyst on the purification plate through the waste gas collector so that the high-temperature waste gas undergoes a chemical reaction and is purified. In addition, by-products such as tar or wood vinegar in the high-temperature waste gas are condensed and recovered through the gas-liquid separator, thereby preventing harmful substances in the high-temperature waste gas from damaging the waste treatment equipment, thereby achieving the effect of extending the service life of the waste treatment furnace. In addition, the waste treatment equipment of the present invention can reduce the temperature of the high-temperature waste gas through the gas exchanger and the gas-liquid separator, and can remove harmful substances in the high-temperature waste gas, and discharge pollution-free gas that meets environmental protection standards and can recover useful synthetic gas containing carbon monoxide (CO), hydrogen (H), methane (CH4), etc. for use, so as to improve the pyrolysis efficiency of the waste, and can achieve the effect of improving the added value of the waste.
