Description

Technical Field

[0001] The present invention relates to the field of domestic waste treatment, and in particular to a mobile treatment station capable of treating domestic waste during movement. Background Art

[0002] For domestic waste, the current collection and treatment method is to transport the waste with traditional vehicles and then treat it in a centralized manner. This method requires the purchase of a considerable number of garbage collection vehicles and the construction of a large number of garbage transfer stations. Not only is the treatment cost high and occupies a lot of land, but the garbage also causes cross-contamination to the surrounding environment during the collection and transportation process. If the garbage is treated on-site in a decentralized manner, the environmental pollution caused by the garbage will be greatly reduced. At present, domestic garbage treatment mainly adopts landfill, composting and incineration technologies. Analysis shows that landfill and composting are no longer suitable for promotion. Garbage incineration will release a lot of heat energy. At present, it is mainly suitable for power generation, which requires a large daily collection volume as a supporting device. Therefore, these technologies are not suitable for decentralized technology applications. In recent years, biomass anaerobic pyrolysis technology has been applied to garbage treatment. After more than ten years of practice, it has been found that garbage through pyrolysis treatment will not produce a large amount of dioxins like incineration, and the amount of flue gas produced is less than half of incineration, and the impact on the environment is very limited. At the same time, pyrolysis treatment of garbage is more suitable for areas with relatively small collection volumes. Therefore, at this stage, the best technology for decentralized on-site treatment of domestic waste is pyrolysis treatment technology. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a mobile domestic waste treatment station, which aims to achieve the purpose of decentralized, convenient and rapid waste treatment without polluting the environment. The technical solution adopted is:

[0004] A mobile pyrolysis treatment station for domestic waste is provided with a treatment station located on a mobile carrier, wherein the mobile carrier is a vehicle suitable for mobile transportation such as a car, a ship, or a train, and the treatment station has a square steel box body, and the interior of the box body is divided into a first combustion chamber and a second combustion chamber by a fire-resistant heat-insulating wall panel, and the first combustion chamber is provided with a controllable pyrolysis bin, an incineration bin, and an ash bin from top to bottom, the controllable pyrolysis bin and the incineration bin are separated by a flip plate, and the incineration plant and the ash bin are separated by a flip grate, the controllable pyrolysis bin is connected to a feeding system, and the garbage enters the controllable pyrolysis bin through the feeding system, and after being decomposed in the controllable pyrolysis bin, a small amount of residues such as bio-tar and coke are formed, and the residues fall into the incineration bin by rotating the flip plate. There is a primary air inlet pipeline inside the incineration bin. One end of the primary air inlet pipeline is connected to the atmosphere, and the other end extends into the incineration bin. The primary air inlet pipeline inputs oxygen from the atmosphere into the incineration bin, providing fresh oxygen for the incineration bin, causing the residue to undergo a combustion reaction, releasing heat energy to continue to supply energy to the controllable pyrolysis bin. The ash generated in the incineration bin is transferred into the ash bin by rotating and flipping the grate. One or more spiral slag dischargers are installed in the ash bin, and a slag outlet is connected below the spiral slag discharger. The ash in the ash bin is discharged out of the treatment station through the spiral slag discharger.

[0005] The first cyclone combustion chamber and the second cyclone combustion chamber are arranged in parallel in the second combustion chamber. The common air outlet of the pyrolysis chamber and the incineration chamber is connected to the air inlet of the first cyclone combustion chamber through the first flue gas passage. The pyrolysis chamber and the incineration chamber share the same common air outlet. The flue gas generated by the pyrolysis chamber and the incineration chamber during operation forms a mixed gas, which enters the first cyclone combustion chamber through the common air outlet and the first flue gas passage. A transition chamber is arranged above the first cyclone combustion chamber. The transition chamber is connected to the air inlet of the second cyclone combustion chamber through the second flue gas passage. One end of the secondary air inlet pipeline is connected to the atmosphere, and the other end is connected to the first flue gas passage. Fresh oxygen in the atmosphere is mixed with the mixed gas and enters the first cyclone combustion chamber. The first cyclone combustion chamber is provided with a pulse dust collector and a quenching heat exchange device in parallel. The second cyclone combustion chamber is provided with a first baffle combustion chamber, a second baffle combustion chamber and a third baffle combustion chamber in parallel. The air outlet of the second cyclone combustion chamber is connected to the air inlet of the first baffle combustion chamber. The rapid cooling heat exchange device and the pulse dust collector are arranged according to the flow direction of the flue gas.

[0006] The air outlet of the third baffle combustion chamber is connected to the smoke elimination and purification system, and the smoke flowing out of the third baffle combustion chamber is discharged to the processing station through the smoke elimination and purification system.

[0007] The above-mentioned mobile domestic waste pyrolysis treatment station, further, has a feeding system with a garbage channel, which is located inside the box body and above the secondary combustion chamber, and is connected to the controllable pyrolysis bin. A pusher is provided in the garbage channel, and the cylinder thruster of the pusher pushes the garbage into the controllable pyrolysis bin. A loading port is provided at the top of the garbage channel, and the loading port has a movable cover. A bucket lift is hung on the outside of the box body, and the bucket lift has a lifting cylinder and a lifting cylinder. The garbage can is hung on the bucket lift and contacts the lifting cylinder and the lifting cylinder. The garbage can moves up and down through the lifting cylinder. When the garbage can moves up to the loading port, the lifting cylinder lifts the garbage can, and the garbage is dumped into the garbage channel.

[0008] The mobile domestic waste pyrolysis treatment station further comprises a purification system composed of a quenching heat exchange device, a pulse dust collector, an adsorption chamber, a smoke conveying pipe and an induced draft fan. The air inlet of the quenching heat exchange device is connected to the air outlet of the third baffle combustion chamber, and the air outlet of the quenching heat exchange device is connected to the pulse dust collector, and the pulse dust collector is connected to the induced draft fan through the adsorption chamber and the smoke conveying pipe. The air inlet and air outlet of the quenching heat exchange device and the pulse dust collector are arranged according to the flow direction of the smoke.

[0009] The above-mentioned mobile domestic waste pyrolysis treatment station, further, has a water-cooling heat sink mounted on the outer wall of the box body, the water-cooling heat sink is connected to the outlet pipe at the bottom of the rapid cooling heat exchange device through an output pipe and a hot water pump, and the water-cooling heat sink is connected to the rapid cooling heat exchange device through the outlet section at the top.

[0010] The mobile domestic waste pyrolysis treatment station further has a primary air inlet pipeline with a vertically arranged primary air inlet pipe, an annular pipe arranged along the circumference of the incineration bin, and a horizontally arranged primary air outlet pipe, wherein the annular pipe is embedded in the wall of the incineration bin, and the two ends of the annular pipe are respectively connected to the primary air inlet pipe and the primary air outlet pipe. The primary air inlet pipeline can be a connecting pipeline in various forms, which plays a role in transporting oxygen in the atmosphere to the incineration bin.

[0011] In the mobile domestic waste pyrolysis treatment station, the primary air outlet pipe is further arranged perpendicular to the side wall of the incineration bin, and a row of primary air outlet pipes are arranged horizontally. The arrangement of a row of primary air outlet pipes can more evenly transport oxygen to the incineration bin, so that the fuel in the incineration bin burns more completely.

[0012] The above-mentioned mobile domestic waste pyrolysis treatment station, further, the first baffle combustion chamber, the second baffle combustion chamber, and the third baffle combustion chamber are interconnected.

[0013] The above-mentioned mobile domestic waste pyrolysis treatment station, further, the first combustion chamber and the second combustion chamber both use refractory insulation walls, and the refractory insulation walls are composed of a casting layer, a thermal insulation layer and an insulation board layer from the inside to the outside, and the outer surface of the insulation board layer is in contact with the inner surface of the box body.

[0014] The above-mentioned mobile domestic waste pyrolysis treatment station, further, operates through its own battery or self-powered electricity.

[0015] The above-mentioned mobile domestic waste pyrolysis treatment station further has an emergency combustion aid interface on the incineration bin wall, and a flue gas emergency bypass valve on the flue gas conveying pipe.

[0016] The beneficial effects of the present invention are:

[0017] 1. The garbage is thermally decomposed while the mobile carrier is moving, which overcomes the traditional method of transporting garbage by vehicles and then centrally treating it. It realizes the harmless treatment of garbage on site in one step, solves the problems of building a garbage disposal site without land available, or having land available but being opposed by the public, and saves the treatment cost to the greatest extent.

[0018] 2. The controllable pyrolysis chamber and incineration chamber of the first combustion chamber are respectively equipped with heat energy utilization facilities. In particular, the waste heat utilization facilities of the incineration chamber can regulate the furnace temperature of the incineration chamber by adjusting the reflux flow, thereby ensuring the stability of combustion, thereby stabilizing the energy supply capacity of the energy storage controllable pyrolysis chamber and ensuring the normal operation of garbage pyrolysis treatment.

[0019] 3. The controllable pyrolysis chamber builds a closed anaerobic environment, and the garbage obtains stable heat energy through multiple channels, ensuring that the garbage undergoes pyrolysis reaction at 500-700°C. Under anaerobic and medium-temperature pyrolysis conditions, the garbage is reduced rapidly, and the reaction is mainly gasification, which prevents the generation of new dioxins. At the same time, the output of combustible gas accounts for a large proportion, and the secondary combustion temperature is high, which meets the "3T+E" conditions in the "Standards for Pollution Control of Domestic Waste Incineration" (GB 18485-2014). The combustion reaction decomposes the dioxins carried by the mixed flue gas from the front end, thereby eliminating the dioxin hazards generated by garbage treatment.

[0020] 4. Garbage generally does not need to be sorted. The humanized design means that people basically do not touch the garbage. The operation is fully mechanized, the labor intensity is low, and the cost of garbage disposal is also reduced to a very low level.

[0021] 5. Except for adding fuel to heat up the equipment when it is started, no auxiliary fuel is needed during the operation of the equipment. The heat energy consumed by garbage treatment comes from the heat released by itself.

[0022] 6. The application of anaerobic pyrolysis technology and flue gas purification technology can effectively remove a variety of complex pollutants in flue gas, especially dioxins, so that the garbage treatment control indicators meet the requirements of the national standard "Pollution Control Standard for Incineration of Domestic Waste GB18485-2014" and achieve qualified emissions.

DETAILED DESCRIPTION

[0034] The present invention will be further described with reference to the accompanying drawings. Figure 1 , 2 A mobile domestic waste pyrolysis treatment station shown in 3 is provided on a vehicle carrier with a treatment station having a hydraulic station control system 53. The hydraulic station is installed at the front end of the treatment station, below the water cooling device, and its function is to control the operation of hydraulic equipment, such as controlling the operation of hydraulic cylinders, hydraulic motors, etc. (such as pushing and returning of a pusher, loading and returning of a bucket lift, etc.). The treatment station is installed on a vehicle 65 through a base 32. The treatment station has a square box made of steel plates, and a fire-resistant heat-insulating wall panel is vertically arranged inside the box. The fire-resistant heat-insulating board divides the inside of the box into a first combustion chamber A and a second combustion chamber B. The first combustion chamber and the second combustion chamber both use a fire-resistant heat-insulating wall 7, which is composed of a casting material layer, a heat-insulating layer and a heat-insulating board layer from the inside to the outside, and the outer surface of the heat-insulating board layer is in contact with the inner surface of the box. The casting material layer is specifically a casting material energy storage ball combination layer, the heat-insulating layer is specifically an aluminum silicate heat-insulating layer, and the heat-insulating board layer is specifically a ceramic fiber heat-insulating board. The refractory castable layer has the fire resistance to withstand high temperatures, the thermal insulation layer and the heat insulation board layer have thermal insulation and heat insulation functions respectively, and the wall is cooled step by step to ensure that the temperature of the outer wall steel plate surface is lower than 50℃.

[0035] like Figure 4 , 5 As shown in 6, in the first combustion chamber, from top to bottom, there are controllable pyrolysis chamber 9, incineration chamber 6, ash chamber 3, a flip plate 8 is arranged between the controllable pyrolysis chamber and the incineration chamber, a flip grate 4 is arranged between the incineration chamber 6 and the ash chamber 3, the flip plate and the flip grate are both fixed in the combustion chamber by bearings, the axial extension end of the flip plate is equipped with a flip cylinder 67 and a push rod 66 for controlling rotation, the axial extension end of the flip grate is equipped with a flip cylinder 67 and a connecting rod mechanism 68 for controlling rotation. A primary air inlet pipeline is arranged in the incineration chamber, the primary air inlet pipeline has a vertically arranged primary air inlet pipe 37, an annular pipe 5 arranged along the circumference of the incineration chamber, and a horizontally placed primary air outlet pipe 38, the annular pipe is embedded in the wall of the incineration chamber, and the two ends of the annular pipe are respectively connected to the primary air inlet pipe and the primary air outlet pipe. A plurality of spiral slag dischargers 2 are fixed in the ash chamber, and below the spiral slag dischargers, the ash chamber is connected to a slag outlet 1. As shown Fig. 9 , 10 As shown, the fuel in the incineration bin burns and generates heat radiation, which raises the temperature of the controllable pyrolysis bin to 500-700°C. The garbage is pyrolyzed in the controllable pyrolysis bin, and the pyrolysis produces a small amount of residues such as bio-tar and coke. The residues are dumped into the incineration bin by rotating the flip plate. The ash slag finally generated by the incineration bin is dumped into the ash slag bin by rotating the flip grate, and discharged through the slag outlet of the ash slag bin. The flip plate and the flip grate can be flipped at an angle of 70-90°. The main products of the controllable pyrolysis bin during the pyrolysis process are combustible gases such as CO, H2, and CH4. After mixing with the flue gas generated during the combustion of the incineration bin, they enter the first cyclone combustion bin through the common gas outlet 13 and the first flue gas passage 14. The common gas outlet is connected to the first cyclone combustion bin through the first flue gas passage 14. The secondary air inlet pipeline has a first air inlet pipe 15 arranged outside the box and a second air inlet pipe 59 arranged inside the box. The first air inlet pipe 15 is transversely fixed on the outer wall of the box, one end of which is connected to the atmosphere and the other end is connected to the second air inlet pipe 59; the second air inlet pipe is arranged vertically inside the box, one end of which is connected to the first air inlet pipe and the other end is connected to the first flue gas passage. An emergency combustion aid interface 57 and a temperature sensor 11 are respectively arranged on the horizontal right wall of the incineration bin, and a temperature sensor 11 is also installed on the opposite wall near the top plate.

[0036] The first cyclone combustion chamber 17 and the second cyclone combustion chamber 41 are arranged side by side in the second combustion chamber. The first cyclone combustion chamber is provided with a pulse dust collector 18 and a rapid cooling heat exchange device 26. The second cyclone combustion chamber is provided with a first baffle combustion chamber 43, a second baffle combustion chamber 47, and a third baffle combustion chamber 49. The first baffle combustion chamber is connected to the second baffle combustion chamber and the third baffle combustion chamber. A transition chamber 75 is arranged above the first cyclone combustion chamber. The first cyclone combustion chamber is connected to the transition chamber 75 through the first cyclone exhaust pipe 74. The transition chamber is connected to the second cyclone combustion chamber through the second passage 16. The first dust exhaust pipe 72 and the second dust exhaust pipe 77 extend from the bottom of the first cyclone combustion chamber and the second cyclone combustion chamber, respectively. After the first dust exhaust pipe and the second dust exhaust pipe are merged, they are connected to the air inlet of the exhaust fan 56 through the smoke recovery outlet pipe 55. The exhaust fan is located in the cavity between the ash bin and the second combustion chamber. A waste heat delivery pipe 39 extends from the exhaust fan outlet. The waste heat delivery pipe extends upward, the pipe mouth extends into the incineration bin, and the pipe mouth is tilted downward. The first dust exhaust pipe, the second dust exhaust pipe, the smoke recovery lead-out pipe, the exhaust fan and the waste heat delivery pipe form a waste heat utilization facility. A temperature sensor is installed in the rear chamber of the exhaust pipe of the second cyclone combustion bin.

[0037] The air outlet of the second cyclone combustion bin is connected to the air inlet of the first baffle combustion bin, the air outlet 51 of the third baffle combustion bin is connected to the air inlet 33 of the quenching heat exchanger, the air outlet 34 of the quenching heat exchanger is connected to one end of the pulse dust collector, the other end of the pulse dust collector is connected to the adsorption bin 20, the adsorption bin is connected to the induced draft fan 22 through the flue gas conveying pipe 71, the function of the induced draft fan is to exhaust the flue gas and maintain a negative pressure environment inside the entire pyrolysis treatment station for a long time. The air inlet and outlet of the quenching heat exchanger and the pulse dust collector are arranged according to the direction of flue gas flow, and the air inlet 33 of the quenching heat exchanger, the air outlet 34 of the quenching heat exchanger, and the air inlet of the pulse dust collector are all arranged at the bottom of the second combustion chamber. The waste heat flue gas flows in from the air inlet of the quenching heat exchanger, and is instantly cooled to below 250°C after the "∩"-shaped reversal of the quenching heat exchanger. After the flue gas flows out from the air outlet of the quenching heat exchanger, it enters the pulse dust collector. An emergency cold air valve 35 is arranged below the air outlet of the quenching heat exchanger. A temperature sensor 11 is also arranged at the air outlet of the quenching heat exchanger to monitor the temperature at the air outlet of the quenching heat exchanger in real time. The adsorption bin, the flue gas conveying pipe and the induced draft fan are located above the quenching heat exchanger and fixed to the outside of the box. A flue gas emergency bypass valve 21 is also arranged on the flue gas conveying pipe. The rapid cooling heat exchange device also has a water-cooling heat sink 23. The rapid cooling device water inlet pipe 24 extending from the top of the water-cooling heat sink passes through the side wall of the box and is connected to the top of the rapid cooling heat exchange device. A relief valve 25 is provided at the place where the water supply pipe is connected to the rapid cooling heat exchange device. The rapid cooling heat exchange device absorbs the heat of the flue gas in the furnace. Hot water is drawn out from the outlet pipe at the bottom through the hot water pump 29 and passes through the output pipe to enter the water-cooling heat sink. The water-cooling heat sink dissipates the heat of the hot water, and the water with the heat dissipated flows into the rapid cooling heat exchange device from the outlet section at the top. The coolant is continuously circulated through this "heat absorption-heat dissipation" to cool the flue gas.

[0038] Since the internal temperature of the rapid cooling heat exchange device and the pulse dust collector is still higher than 200℃, the wall is mainly insulated with insulation panels, and the outermost layer is the outer wall steel plate.

[0039] A garbage channel is provided inside the box body and above the second combustion chamber. A feed port 45 is provided at the top of the garbage channel. One end of the garbage channel is connected to the controllable pyrolysis bin. A pusher 50 is provided in the garbage channel. The pusher has a cylinder propeller 48 that pushes the garbage into the controllable pyrolysis bin for pyrolysis (such as Figure 7 , 8As shown). The feed port is provided with a movable cover 44, which is fixed at the feed port by an opening and closing cylinder 46. When the movable cover covers the feed port, a completely sealed controllable pyrolysis chamber is formed. A bucket lift 64 is mounted on the outer wall of the box body. The bucket lift is provided with a control oil pipe 63 and a lifting cylinder 62. The trash can is moved up and down by the lifting cylinder 62. The bucket lift is provided with a lifting cylinder 61. The lifting cylinder is in contact with the trash can, so that the trash can can be lifted and the trash in the trash can can be poured into the trash channel through the feed port (as shown). Figure 7 As shown in the figure), the garbage is pushed into the controllable pyrolysis bin using the cylinder propeller of the pusher.

[0040] Before using the mobile domestic waste pyrolysis treatment station to treat garbage, the furnace temperature of the first combustion chamber is first raised to the range of 700-900°C using biomass fuel, and then the fuel supply is stopped and switched to the garbage treatment mode (i.e., operating condition). By burning fuel in the incineration bin, high-temperature thermal radiation is generated, and the temperature of the controllable pyrolysis bin is raised to 500-700°C, and the garbage is pyrolyzed in the controllable pyrolysis bin. Under the operating condition, the feed port is sealed by a movable cover, and the inverted grate 4 is filled with garbage and isolated from the incineration bin to form a closed and oxygen-free controllable pyrolysis bin. Under the negative pressure suction of the induced draft fan, the flue gas generated in the pyrolysis bin during the pyrolysis process flows out through the common air outlet and flows to the first cyclone combustion bin. During the operating condition, the incineration bin is sucked by the negative pressure of the induced draft fan, and the external air enters the incineration bin through the primary air inlet pipeline. The air enters the incineration bin and reacts with the combustibles to produce a combustion reaction, and the generated flue gas flows out through the common air outlet and flows to the first cyclone combustion bin.

[0041] The mixed gas formed at the common air outlet of the controllable pyrolysis chamber and the incineration chamber flows into the first cyclone combustion chamber from the side at a flow rate of 14-18m / s, and the external atmospheric gas enters the first flue gas aisle through the secondary air inlet pipeline. The combustible gas is instantly ignited in the presence of oxygen and flue gas above 700°C, and the combustion reaction airflow rotates at a high speed in the first cyclone combustion chamber and the second cyclone combustion chamber. As the direction of the airflow changes continuously, the mixed gas is fully burned at a greater degree of turbulence. The mixed airflow passes through the two-stage cyclone combustion chamber successively, and then enters the first baffle combustion chamber, the second baffle combustion chamber, and the third baffle combustion chamber to continue burning. Since the anaerobic pyrolysis of garbage produces combustible gas with a higher calorific value, the gas temperature of the entire secondary combustion process is higher than 850°C, and the flue gas is repeatedly baffled from the first to the third baffle combustion chambers, ensuring that the entire combustion residence time is more than 3 seconds. The waste heat flue gas generated after the combustion is completed finally flows from the air outlet of the third baffle combustion chamber into the air inlet of the rapid cooling heat exchange device. During the secondary combustion process, the first cyclone combustion chamber and the second cyclone combustion chamber both produce a dust removal effect. The smoke carrying heat energy and a small amount of high-temperature flue gas are discharged from the first dust exhaust port and the second dust exhaust port, and gathered in the smoke recovery outlet pipe. The exhaust fan is started to discharge the high-temperature flue gas in the smoke recovery outlet pipe into the incineration chamber, which plays a role in accelerating the combustion reaction and removing smoke.

[0042] After the waste heat flue gas flows out from the air outlet of the third baffle combustion chamber, it enters the air inlet of the rapid cooling heat exchange device. After being processed by the rapid cooling heat exchange device, the waste heat flue gas is cooled to below 250°, the water temperature on the water side of the rapid cooling heat exchange device increases, and the hot water is restored to low temperature and recycled through the external water cooling device. The flue gas is intercepted by the pulse dust collector, and harmful components such as smoke and heavy metals are fully intercepted and removed. The outflowing flue gas then enters the adsorption chamber to remove the harmful substances such as dust and heavy metals that have escaped the net. After purification, the flue gas that meets the emission standards is discharged into the atmosphere through the flue gas conveying pipe and the induced draft fan.

[0043] Whenever the mobile domestic waste pyrolysis treatment station arrives at a garbage recycling point, the garbage can be processed after being poured into the garbage channel. The domestic waste is effectively pyrolyzed while the mobile carrier is moving, which makes the domestic waste treatment harmless and reduced in one step.
