Description

Technical Field

[0001] The invention relates to garbage processing equipment, in particular to a large-scale garbage processing machine. Background Art

[0002] Heterogeneous biomass pyrolysis and gasification technology is a hot research field at present, because the treatment and resource utilization of domestic waste, industrial waste, and agricultural and forestry waste included in the country's environmental protection energy strategy all belong to this field.

[0003] The existing temporary garbage disposal equipment usually has a relatively small processing capacity, and the temporary garbage disposal equipment is made into a non-disassembly structure, and even the main manufacturing process is completed at the project site, and the equipment cannot be disassembled and moved. For cleaning landfills or emergency treatment projects, usually only temporary equipment is required with a large processing capacity, and the equipment needs to be dismantled after 1-3 years of use. The existing pyrolysis gasification furnace usually has a shell and a base cast with cement. If the existing pyrolysis gasification furnace is used, it cannot be used after dismantling, and the equipment is still within its service life when it is dismantled, which causes great waste. Therefore, technical personnel in this field are in urgent need of a large garbage disposal machine that is easy to transport and disassemble. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a large-scale garbage disposal machine which is convenient for transportation and disassembly.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a large-scale garbage disposal machine comprises a feeding device, an assembled pyrolysis gasification furnace, an exhaust gas treatment equipment and a chimney which are connected in sequence, the exhaust gas treatment equipment comprises a two-fuel quenching heat exchange box, a dust removal, desulfurization and denitrification box and a wet electrostatic precipitator and demisting box which are connected in sequence, the two-fuel box inlet of the two-fuel quenching heat exchange box is connected to the pyrolysis gas outlet of the assembled pyrolysis gasification furnace, and the outlet of the wet electrostatic precipitator and demisting box is connected to the chimney.

[0006] The beneficial effects of the present invention are as follows: a large-scale garbage disposal machine adopts an exhaust gas treatment equipment composed of an assembled pyrolysis gasification furnace and a plurality of box-type equipment; the secondary combustion rapid cooling heat exchange box, the dust removal, desulfurization and denitrification box and the wet electrostatic precipitator and mist removal box can be stacked and placed, and the structure is convenient for disassembly, assembly and transportation; it occupies a small area; no factory building is required, investment is saved, and the process is simplified; it is de-factorized and the "NIMBY effect" is eliminated.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the exhaust gas treatment equipment also includes a flue gas spray water comprehensive treatment box, the wastewater outlets of the dust removal, desulfurization and denitrification box and the wet electrostatic precipitator and demisting box are connected to the oily hot water inlet of the flue gas spray water comprehensive treatment box, and the spray water outlet of the flue gas spray water comprehensive treatment box is respectively connected to the dust removal, desulfurization and denitrification box and the spray pipes in the wet electrostatic precipitator and demisting box.

[0009] The beneficial effect of adopting the above further scheme is that the garbage disposal machine is equipped with a flue gas spray water comprehensive treatment box, and the generated spray waste water can be directly treated and recycled to avoid pollutant emissions. The flue gas spray water comprehensive treatment box is a box structure, which can be stacked with the exhaust gas treatment equipment to save space and have a compact structure.

[0010] Furthermore, the exhaust gas treatment equipment also includes an activated carbon adsorption box and a smoke exhaust fan, and the outlet of the wet electrostatic precipitator and mist removal box, the activated carbon adsorption box, the smoke exhaust fan and the chimney are connected in sequence.

[0011] The beneficial effects of adopting the above further scheme are: the activated carbon adsorption box further adsorbs the untreated particles or substances, and the smoke exhaust fan increases the air flow rate in the device, so that the smoke can smoothly enter the chimney.

[0012] Furthermore, there are at least two tail gas treatment devices, the secondary fuel box inlets of at least two secondary fuel quenching heat exchange boxes are connected to the pyrolysis gas outlet of the assembled pyrolysis gasifier, and at least two exhaust fans are connected to the chimney.

[0013] The beneficial effect of adopting the above further scheme is that the tail gas treatment equipment can be adjusted according to the amount of flue gas to be treated, and the tail gas treatment equipment can be one or more. When there are multiple tail gas treatment equipment, multiple tail gas treatment equipment are connected in parallel. The container modular tail gas treatment device has the following advantages: the treatment capacity can be adjusted arbitrarily; the box structure is convenient for disassembly and transportation; it occupies less space; no factory is required, saving investment and simplifying the process; de-factorization eliminates the "NIMBY effect".

[0014] Furthermore, the flue gas spray water comprehensive treatment box includes a treatment box body and an oil-water separation device, a waste hot water tank, a filter press device, a clear hot water tank, a heat exchange device and a cool water tank arranged in the treatment box body; the side wall of the treatment box body has the oil-water hot water inlet, the oil-water hot water inlet is connected to the oil-water separation device, the waste hot water outlet of the oil-water separation device is connected to the inlet of the filter press device through the waste hot water tank, the outlet of the filter press device is connected to the heat medium inlet of the heat exchange device through the cool water tank, and the heat medium outlet of the heat exchange device is connected to the spray water outlet of the treatment box body through the cool water tank.

[0015] The beneficial effect of adopting the above further scheme is that the flue gas spray water passes through the oil-water separation device to separate the dirty hot water and tar, the dirty hot water passes through the filter press device to filter the sludge, and then the dirty hot water passes through the heat exchange device to cool down to obtain spray water that can be used again. The dirty hot water tank provides a buffer and storage area for the dirty hot water. After the dirty hot water is filtered by the filter press device, it forms clear hot water. The clear hot water tank provides a buffer and storage area for the clear hot water. After the clear hot water is cooled by the heat exchange device, it becomes clear cold water. The clear cold water tank provides a buffer and storage area for the clear cold water. The flue gas spray water comprehensive treatment box is integrated in a box body, with a compact structure, fast spray water treatment, and has the functions of oil-water separation, particle filtration, forced spray water heat exchange and cooling, so that the spray water can be comprehensively treated and recycled, and zero discharge of spray water is achieved.

[0016] Furthermore, the flue gas spray water comprehensive treatment box also includes a tar tank and an alkali liquid tank, the tar tank is connected to the tar outlet of the oil-water separation device; the outlet of the alkali liquid tank is connected to the cool water tank.

[0017] The beneficial effect of adopting the above further scheme is that the tar separated by the oil-water separation device is stored in the tar tank and can be cleaned regularly. The alkali solution in the spray water is consumed during the adsorption process, and the alkali solution tank replenishes the alkali solution into the cool water tank, so that the cool water can be used as spray water to play the role of dust reduction and adsorption.

[0018] Furthermore, the assembled pyrolysis gasification furnace includes an insulation shell, a reactor, a chain-discharge hot air furnace and a dryer, the reactor being rotatably installed in the insulation shell, one end of the reactor extending out of the insulation shell and having a feed inlet, the side wall of the reactor having a carbon slag discharge port connected to the chain-discharge hot air furnace, the insulation shell being detachably connected to the upper end of the chain-discharge hot air furnace, the insulation shell being composed of a plurality of insulation plates detachably connected; the dryer being rotatably installed in the insulation shell and being located above the reactor, both ends of the dryer extending out of the insulation shell, one end of the dryer having a dryer inlet connected to the feeding device, and the other end having a dryer outlet, the dryer outlet being connected to the feed inlet; one end of the reactor having the pyrolysis gas outlet, the top wall of the insulation shell also having an insulation shell pyrolysis gas outlet, the pyrolysis gas outlet and the insulation shell pyrolysis gas outlet are both connected to the inlet of the secondary combustion quenching heat exchange box.

[0019] The beneficial effects of adopting the above further scheme are: multiple insulation boards, reactors and chain-discharge hot air furnaces can be transported separately, assembled on site, and can be dismantled and transported away after temporary use without affecting the next use. The dryer uses the temperature in the insulation shell to dry and preheat the material before entering the reactor, so that the material processing efficiency is high and the combustion is sufficient. The material is pyrolyzed in the reactor, and the carbon slag after pyrolysis enters the chain-discharge hot air furnace for combustion and heat for the insulation shell, and the pyrolysis gas enters the tail gas treatment equipment for treatment.

[0020] Furthermore, there are two reactors, which are arranged side by side, the feed inlets of the two reactors are connected to the dryer outlet, and the carbon slag discharge ports of the two reactors are connected to the chain-discharge hot air furnace.

[0021] The beneficial effect of adopting the above further solution is that: by adopting two reaction kettles, a large amount of materials can be processed, and the processing efficiency is improved. The large-scale garbage disposal machine of the present invention can process 500 tons or even more materials at a time.

[0022] Furthermore, the assembled pyrolysis gasification furnace also includes a distributor, the dryer outlet and the feed inlet are correspondingly arranged at one end of the insulation shell, the distributor is installed below the dryer outlet and above the feed inlet, and feeds the material discharged from the dryer outlet into the feed inlet of the reactor.

[0023] The beneficial effect of adopting the above further solution is that the distributor allows the material discharged from a dryer to enter one or more reaction kettles.

[0024] Furthermore, the secondary combustion rapid cooling heat exchanger box includes a secondary combustion chamber and a heat exchanger which are arranged in the secondary combustion heat exchanger box body and are interconnected. The secondary combustion heat exchanger box body is provided with a secondary combustion box inlet and a secondary combustion box outlet which are respectively connected to the secondary combustion chamber and the heat exchanger. The interior of the secondary combustion chamber is divided into a plurality of chambers which are connected in sequence by a partition. A flow channel is formed between the end of the partition and the side wall of the secondary combustion chamber, or the partition has a flow channel, and two adjacent chambers are connected through the flow channel. The flow channel is filled with heat storage ceramic porous bricks, and the heat storage ceramic porous bricks have a plurality of flow holes, and two adjacent chambers are connected through the flow holes.

[0025] The beneficial effect of adopting the above further scheme is that the secondary combustion quenching heat exchange box is a box structure, which can be installed in a modular manner and has a compact structure. The secondary combustion chamber adopts multiple chambers, which can increase the gas residence time, increase the heat storage area, and facilitate full reaction and combustion. Multiple chambers share partition walls, saving material investment. In addition, there is no need to connect the secondary combustion chamber and the secondary combustion chamber and the heat exchanger with air ducts, eliminating system wind resistance and reducing pressure loss. The heat storage ceramic porous bricks serve as gas channels on the partitions, which are conducive to dispersing and evenly distributing airflow and uniform reaction. At the same time, they increase the contact surface between the gas and the heat storage body, which is conducive to heat storage and heat release, so as to balance the combustion temperature of the secondary combustion chamber and adapt to the heterogeneity and instability of the raw materials. When processing heterogeneous materials, the heat generated by garbage from different places after treatment is different. For example, the garbage transported from the community is mainly plastic products, which generates a lot of heat; the garbage transported from the vegetable market is mainly vegetable leaves, which generates less heat. When processing garbage, different types of garbage are processed successively, making the temperature in the secondary combustion chamber unstable and the gas treatment effect poor. If the heat after the previous batch of garbage is processed is large, the heat storage ceramics can absorb the heat and keep the temperature constant. If the heat after the subsequent garbage is processed is small, the heat storage ceramics release heat to raise the temperature of the gas and balance the heat. BRIEF DESCRIPTION OF THE DRAWINGS

[0097] As a further solution of this embodiment, Figure 8-Figure 19As shown, the assembled pyrolysis gasification furnace 2 includes an insulation shell 21, a reactor 22, a chain-discharge hot air furnace 23 and a dryer 24. The reactor 22 is rotatably installed in the insulation shell 21. One end of the reactor 22 extends out of the insulation shell 21 and has a feed inlet 2211. The side wall of the reactor 22 has a carbon slag discharge port 2213 connected to the chain-discharge hot air furnace 23. The insulation shell 21 is detachably connected to the upper end of the chain-discharge hot air furnace 23. The insulation shell 21 is composed of a plurality of detachable insulation plates. The dryer 24 is rotatable. It is installed in the insulation shell 21 and is located above the reactor 22. Both ends of the dryer 24 extend out of the insulation shell 21, one end of which has a dryer inlet connected to the feeding device 1, and the other end has a dryer outlet, and the dryer outlet is connected to the feed port 2211; one end of the reactor 22 has the pyrolysis gas outlet 2212, and the top wall of the insulation shell 21 also has an insulation shell pyrolysis gas outlet, and the pyrolysis gas outlet 2212 and the insulation shell pyrolysis gas outlet are both connected to the inlet of the secondary combustion quenching heat exchange box 31.

[0098] Specifically, the side wall of the insulation shell 21 also has an insulation shell pyrolysis gas outlet, and the pyrolysis gas discharged from the carbon slag discharge port 2213 is discharged through the insulation shell pyrolysis gas outlet and enters the subsequent secondary combustion rapid cooling heat exchange box 31.

[0099] Specifically, Fig.12 As shown, the dryer 24 is a cylindrical barrel structure, and the inner wall of the dryer 24 is provided with a guide thread, so when the dryer 24 rotates, the material will move from the dryer inlet to the dryer outlet along the guide thread. Since the dryer 24 rotates continuously and is heated evenly, the dryer 24 made of ordinary steel will not bend or deform in the high-temperature insulation shell 21.

[0100] Specifically, a dryer gear ring 242 is sleeved on the outer side of one end of the dryer 24, a dryer drive motor is arranged outside the heat preservation shell 21, a dryer transmission gear is fixed to the output end of the dryer drive motor, and the dryer transmission gear meshes with and transmits the dryer gear ring 242. The dryer transmission gear and the dryer gear ring 242 can also be connected by a gear set. Specifically, dryer rollers 24 are sleeved on both ends of the dryer 24.

[0101] As a further solution of this embodiment, there are two reactors 22, and the two reactors 22 are arranged side by side. The feed inlets 2211 of the two reactors 22 are connected to the dryer outlet, and the carbon slag discharge ports 2213 of the two reactors 22 are connected to the chain-discharge hot air furnace 23.

[0102] As a further solution of this embodiment, the assembled pyrolysis gasification furnace 2 also includes a distributor 25. The dryer outlet and the feed inlet are arranged at one end of the insulation shell 21 correspondingly. The distributor 25 is installed below the dryer outlet and above the feed inlet 2211, and delivers the material discharged from the dryer outlet into the feed inlet 2211 of the reactor 22.

[0103] like Figure 15-19 As shown, the reactor 22 includes a reactor barrel body 221, a feeding mechanism 222 and a reactor driving mechanism 223. The reactor barrel body 221 is a horizontally arranged cylindrical barrel body. One end of the reactor barrel body 221 has the feeding port 2211 and the pyrolysis gas outlet 2212. The side wall of the reactor barrel body 221 has the carbon slag discharge port 2213. The feeding mechanism 222 is rotatably connected and communicated with the feeding port 2211. The reactor driving mechanism 223 is transmission-connected to the reactor barrel body 221 and drives the reactor barrel body 221 to rotate axially.

[0104] The reactor 22 is a horizontal countercurrent pyrolysis reactor, which is particularly used for the pyrolysis treatment of heterogeneous organic solid waste (solid waste). It avoids the need for a vertical pyrolysis reactor to perform pre-homogenization treatment on the heterogeneous organic solid waste, thereby reducing the treatment cost. Its countercurrent feed and gas outlet design also has the thermal energy utilization advantage of a vertical reactor (furnace).

[0105] Specifically, the reactor drive mechanism 223 is a motor. The reactor drive mechanism 223 is connected to the reactor barrel 221 through gear transmission. Specifically, the output shaft fixed sleeve of the reactor drive mechanism 223 is provided with a first gear, and the outer fixed sleeve of the other end of the reactor barrel 221 is provided with a ring-shaped second gear. The first gear and the second gear are meshed and driven to drive the reactor barrel 221 to rotate around its axis. A transmission gear set can also be set between the first gear and the second gear. The first gear and the second gear are both meshed with the transmission gear set, and the first gear transmits power to the second gear through the transmission gear set. The reactor drive mechanism 223 and the reactor barrel 221 can also be connected through belt drive or chain drive.

[0106] Specifically, both ends of the reactor barrel 221 extend out of the insulation shell 21 and can rotate relative to the insulation shell 21, and both ends of the reactor barrel 221 are respectively sleeved with reactor rollers 228. In order to prevent the high temperature in the insulation shell from affecting the movement of the mechanism, the reactor roller 228, the first gear, the second gear and the reactor driving mechanism 223 are all located outside the insulation shell 21.

[0107] As a further solution of this embodiment, the carbon slag discharge port 2213 is arranged on the side wall of the reactor barrel body 221 close to the other end thereof.

[0108] As a further solution of this embodiment, a discharge door 224 is further included, and one end of the discharge door 224 is hinged to one side of the carbon slag discharge port 2213 along the circumference of the reactor barrel body 221.

[0109] As a further solution of this embodiment, the discharge door 224 has a plurality of sieve holes.

[0110] Specifically, Fig.16 , Fig.18 and Fig.19 As shown, one end of the discharge door 224 is hinged to the reactor barrel 221, and the discharge door 224 is opened or closed as the reactor barrel 221 rotates. Fig.19 As shown, 1-1 to 1-4 in the figure show the states of the discharge door 224 at four positions during the counterclockwise rotation of the reactor barrel 221. The counterclockwise rotation of the reactor barrel 221 is the pyrolysis state of the horizontal countercurrent pyrolysis reactor. The counterclockwise rotation means that the hinge point of the discharge door 224 is located at the rear of the rotation direction. When the discharge door 224 rotates to the bottom, that is, at the position shown in 1-3, the discharge door 224 is closed. Fig.19 As shown, 2-1 to 2-4 in the figure represent the states of the discharge door 224 at four positions during the clockwise rotation of the reactor barrel 221. The clockwise rotation of the reactor barrel 221 is the discharge state of the horizontal countercurrent pyrolysis reactor. The clockwise rotation indicates that the hinge point of the discharge door 224 is located in front of the rotation direction. When the discharge door 224 rotates to the bottom, that is, at the position shown in 2-3, the discharge door 224 is opened.

[0111] Specifically, in the material processing process, the non-homogeneous materials include inorganic materials that cannot be pyrolyzed and organic materials that can be pyrolyzed, wherein the organic materials include materials that are easy to pyrolyze and materials that are not easy to pyrolyze. The materials that are not easy to pyrolyze include furniture and wood, and the materials that are easy to pyrolyze include plastic films and plastic lunch boxes. Since the non-homogeneous materials are not classified and homogenized before being put into the reactor barrel 221, the materials that are easy to pyrolyze will be pyrolyzed into carbon slag first, and the materials that are not easy to pyrolyze will be pyrolyzed into carbon slag after a longer pyrolysis period. Therefore, in the pyrolysis state, when the reactor barrel 221 rotates to Fig.19 In the state 1-3, the carbon slag can be directly discharged through the sieve holes on the discharge door 224 during the pyrolysis process. If a large amount of inorganic materials that cannot be pyrolyzed are accumulated in the reactor barrel 221, the reactor drive mechanism 223 drives the reactor barrel 221 to rotate clockwise. In the discharge state, the reactor barrel 221 rotates to Fig.19In the 2-3 state, the material that cannot be pyrolyzed is discharged from the carbon slag discharge port 2213. The beneficial effect is that the reactor barrel 221 needs to work at high temperature. If it is set as a closed discharge door, it is necessary to wait for the reactor barrel 221 to cool down before it can be opened manually when discharging is required. This not only greatly reduces the production efficiency, but also wastes heat energy. After restarting the pyrolysis reactor, it still needs to be reheated, and the heat energy loss is large. The discharge door 224 of the present invention can be used to discharge materials without stopping the machine, and the production efficiency is high. And after a large number of experiments, it has been proved that in the 1-1, 1-2, 1-4, 2-1, 2-2 and 2-4 states, the material will not fall out of the reactor barrel 221, which solves the problem of discharging non-homogeneous materials during pyrolysis in the reactor.

Specifically, the pyrolysis gas guide barrel 225 extends out of the insulation shell 21, and the reactor roller 228 located at one end of the reactor barrel body 221 is sleeved on the outside of the pyrolysis gas guide barrel 225.

[0113] As a further solution of this embodiment, the feeding mechanism 222 includes a feeding barrel 2221 and a pushing mechanism 2222. One end of the feeding barrel 2221 is open and extends into the feeding port 2211, and the pushing mechanism 2222 is fixedly arranged on the inner side of the other end. The pushing mechanism 2222 is used to push the material from the feeding barrel 2221 into the reactor barrel body 221. The middle side wall of the feeding barrel 2221 has a material input port 22211. Specifically, the feeding mechanism 222 is fixed, one end of the feeding barrel 2221 is rotatably connected to the feeding port 2211 through a bearing and sealed by a seal, and the pyrolysis gas guide barrel 225 rotates on the outside of the feeding barrel 2221 along with the reactor barrel body 221.

The hydraulic cylinder is fixedly arranged at the other end of the feed barrel 2221, and the output end of the hydraulic cylinder is fixedly connected to the pushing plate, and drives the pushing plate to push the material from the feed barrel 2221 into the reactor barrel body 221.

[0115] As a further solution of this embodiment, the feeding mechanism 222 further includes a feeding hopper 2223 , and the feeding hopper 2223 is fixedly connected to the feeding barrel 2221 and is correspondingly arranged above the material input port 22211 .

[0116] As a further solution of this embodiment, a leakage prevention net 226 is also included. The leakage prevention net 226 is detachably connected to the pyrolysis gas guide barrel 225 and is correspondingly arranged at the pyrolysis gas outlet 2212.

[0117] Specifically, the anti-leakage net 226 can be a metal net, which can discharge the pyrolysis gas and prevent the material from leaking out of the pyrolysis gas outlet 2212. If the anti-leakage net 226 is blocked by the material, the anti-leakage net 226 can be removed for cleaning. Specifically, the pyrolysis gas outlet 2212 is connected to the secondary combustion quenching heat exchange box 31 through a pipeline. Further, a pyrolysis gas exhaust fan is provided on the pipeline connected to the pyrolysis gas outlet 2212. The pyrolysis gas exhaust fan extracts the pyrolysis gas at the pyrolysis gas outlet 2212 and sends it to the secondary combustion quenching heat exchange box 31.

[0118] As a further solution of this embodiment, a plurality of material lifting plates 227 are further included, and the plurality of material lifting plates 227 are fixedly disposed on the inner side of the reactor barrel body 221 .
