Description

Technical Field

[0001] The present application relates to the technical field of waste treatment, and in particular to a vehicle-mounted mobile domestic waste dry distillation and incineration treatment system. Background Art

[0002] The collection and transportation of domestic waste is a key link in urban and rural environmental governance. At present, traditional garbage trucks are widely used for the collection, compression, temporary storage and transportation of garbage. However, the core limitation of this model is that it only undertakes the spatial transfer function of garbage and is unable to substantially render the garbage harmless and reduce its volume during transportation. This leads to a key technical problem: during the long-term retention and transportation of garbage in the car, it inevitably ferments in an anaerobic environment, producing a large amount of foul-smelling gases and leachate. These pollutants can easily escape or leak along the way, causing serious secondary pollution to the air, soil and water. Especially for large rural and urban areas where garbage generation points are scattered and transportation distances are long, this pollution problem caused by transportation itself is particularly prominent and difficult to solve.

[0003] Therefore, there is an urgent need in the existing technology for a vehicle-mounted mobile domestic waste distillation and incineration treatment system that can break through the limitations of traditional garbage trucks of "only transporting but not treating", and simultaneously achieve efficient harmless treatment during the movement of garbage collection and transportation, eliminating the secondary pollution problem in the transfer link.

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0020] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "plurality" means two or more, unless otherwise specifically specified.

[0021] See Figures 1 to 3The embodiments of the present application provide a vehicle-mounted mobile dry distillation and incineration system for treating domestic waste, comprising a vehicle body 1 and a waste treatment chamber 2 mounted on the vehicle body 1. The waste treatment chamber 2 has waste treatment capabilities, while the vehicle body 1 has mobile transportation capabilities. The combination of the two allows for complete waste treatment during transportation, effectively preventing secondary pollution caused by waste during transportation. The waste treatment chamber 2 comprises a first combustion device 21, a second combustion device 22, a heat exchange and cooling device 23, and a purification and emission device 24. The first combustion device 21 is used to dry distill waste, incinerate the semi-coke fuel produced by dry distillation, and collect the resulting ash. The semi-coke fuel primarily consists of a mixed combustible material, such as tar, coke, and a small amount of inorganic matter, produced by the gasification of biomass char. The second combustion device 22 is connected to the first combustion device 21 and is used to burn the combustible gas from the first combustion device 21 to produce ultra-high-temperature decomposition of harmful substances, primarily dioxins. The heat exchange and cooling device 23 is connected to the second combustion device 22 and is used to receive flue gas from the second combustion device 22 and perform heat exchange and cooling on the flue gas. The purification and discharge device 24 is connected to the heat exchange and cooling device 23, and is used to receive the cooled flue gas cooled and exchanged by the heat exchange and cooling device 23, and discharge the cooled flue gas into the atmosphere after purification.

[0022] The technical solution provided in this application is to arrange the garbage disposal chamber 2 on the vehicle body 1, so that the garbage disposal chamber 2 can not only ensure that it can process garbage itself, but also move along with the vehicle body 1, thereby achieving harmless treatment of garbage during transportation. In detail, the garbage disposal process is as follows: first, the collected garbage is subjected to dry distillation treatment using the first combustion device 21, so that the garbage undergoes a thermochemical conversion reaction in the first combustion device 21, converting the garbage into combustible gases mainly composed of CH4, H2, CO, and CmHm and semi-coke fuel mainly composed of tar coke. The semi-coke fuel is then sent to the incineration bin for complete combustion to obtain sufficient heat energy for the dry distillation bin to carry out garbage dry distillation. The ash after the semi-coke combustion is temporarily stored and cooled in the ember bin; the combustible gas is then further burned in the second combustion device 22 to obtain an ultra-high temperature to decompose harmful substances present in the combustible gas, such as dioxins; then, the flue gas generated by the combustion of the second combustion device 22 is subjected to heat exchange and cooling by the heat exchange and cooling device 23, thereby forcing the decomposed dioxins to be unable to be re-synthesized; finally, the flue gas that has undergone heat exchange and cooling is purified by the purification and discharge device 24 and discharged into the atmosphere, thereby achieving harmless treatment of the garbage during transportation, effectively solving the problem of secondary pollution easily caused by traditional garbage trucks during garbage transportation.

[0023] In some embodiments, see Figure 1 and Figure 2, the first combustion device 21 includes a first refractory wall group 211, a partition panel 212, a tilting grate 213 and an energy storage grate 214. The first refractory wall group 211 includes a plurality of first refractory walls, and the plurality of first refractory walls together define a first combustion chamber. The partition panel 212, the energy storage grate 214 and the tilting grate 213 are rotatably arranged in the first combustion chamber from top to bottom. As for the first refractory wall group 211, it is surrounded by a plurality of first refractory walls. The inner layer of each first refractory wall can be made of a high-temperature resistant wall with good thermal conductivity and an outer layer of an aluminum silicate fiberboard with good thermal insulation performance, which mainly plays the role of forming the first combustion chamber and conducting heat inside and insulating heat outside. In this embodiment, the first refractory wall is refractory and heat-insulating. The partition plate 212, on a side away from the energy storage grate 214, and the first refractory wall group 211 together define a feed partition drying chamber 215. The partition plate 212, the energy storage grate 214, and the first refractory wall group 211 together define a retorting chamber 216. The energy storage grate 214, the tilting grate 213, and the first refractory wall group 211 together define an incineration chamber 217. The tilting grate 213 and the first refractory wall group 211 together define an ember chamber 218. Among them, the feed partition drying chamber 215 is used to temporarily store garbage and receive heat from the distillation chamber 216 and the first refractory wall group to dry the garbage; the distillation chamber 216 is used to distill the garbage to convert the garbage into combustible gas and semi-coke fuel; the incineration chamber 217 is used to incinerate the semi-coke fuel and form ash, while providing heat energy for the distillation chamber 216; the ember chamber 218 is used to temporarily store and cool the ash.

[0024] It should be noted that the rotation of the partition plate 212, the energy storage grate 214, and the tilting grate 213 can all be driven by motors or hydraulics, without specific limitations. The rotation drive structures of the partition plate 212, the energy storage grate 214, and the tilting grate 213 are identical. Here, a simple example of the drive of the energy storage grate 214 is provided: Both ends of the energy storage grate 214 can be fixed to bearing seats (not shown), allowing the energy storage grate 214 to maintain a fixed position while also allowing for rotation. A shaft-end push arm (not shown) is then connected to the shaft-end pin hole of the hydraulic cylinder via a shaft pin (not shown). By controlling the in and out movement of the cylinder shaft, the shaft-end push arm is pushed, thereby causing the energy storage grate 214 to rotate about its axis. The energy storage grate 214 tilts at an angle ranging from 75° to 85°, causing fuel accumulated on the surface of the energy storage grate 214 to lose its support and fall, thereby achieving the working conditions of the energy storage grate 214 turning over to discharge or turning the energy storage grate 214 back to its original position. It is understood that the rotation method and rotation structure of the partition plate 212, the energy storage grate 214, and the tilting grate 213 are all existing and mature rotating structures, and are only briefly described above and will not be repeated.

[0025] Furthermore, a first air supply mechanism 2111 and an annular air duct 2112 are provided within the first fireproof wall assembly 211. The air supply end of the first air supply mechanism 2111 is connected to the annular air duct 2112, which is disposed around the incineration chamber 217. By utilizing the first air supply mechanism 2111 and the annular air duct 2112, external air can be delivered into the incineration chamber 217 through the first air supply mechanism 2111, thereby maintaining an oxygen-rich environment within the incineration chamber 217 and ensuring smooth combustion within the incineration chamber 217. The first air supply mechanism 2111 can be a fan, with its air inlet connected to the outside world and its air outlet connected to the annular air duct 2112, thereby delivering air into the incineration chamber 217.

[0026] The treatment process of garbage in the first combustion device 21 is as follows: First, the garbage is poured into the feed partition drying bin 215, which temporarily stores the garbage. Then, when the system is first run, a separate combustion source needs to be supplied. For example, a portion of fuel can be pre-placed in the incineration bin 217. Then, when the garbage is temporarily stored in the feed partition drying bin 215, the fuel in the incineration bin 217 is ignited. The ignition method can be electronic ignition or manual ignition, etc. The ignition method is a conventional technology and is not limited. After the fuel is burned, the temperature in the incineration bin 217 rises rapidly, and the heat energy is radiated and transferred to the furnace wall through the energy storage grate 214 and the first refractory wall group 211, causing the temperature in the retort bin 216 to rise rapidly. The temperature of the feed partition drying bin 215 will also rise, which has a drying effect on the temporarily stored garbage. After the garbage is dried, the partition bin plate 212 is controlled to rotate, and the dried garbage falls into the retort bin 216 under the action of its own gravity. The domestic waste in the retort chamber 216 gradually undergoes a thermochemical conversion reaction under high temperature. When the temperature of the furnace wall and the energy storage grate 214 reaches 500°C to 750°C, the domestic waste is ultimately converted into combustible gases mainly composed of CH4, H2, CO, and CmHm, and semi-coke fuel mainly composed of tar and coke. This semi-coke fuel accumulates on the energy storage grate 214, while the combustible gases flow into the second combustion device 22. When the semi-coke fuel accumulates to a certain amount on the energy storage grate 214, the energy storage grate 214 is controlled to rotate, causing the semi-coke fuel to fall into the incineration chamber 217 under its own gravity. Under the conditions of continuous air supply and high temperature, the semi-coke fuel burns vigorously, and the temperature in the incineration chamber 217 can reach 850°C to 1000°C. At this moment, the high temperature heat energy in the incineration bin 217 will produce the effects such as strong radiation, strong convection and heat conduction, so that the high temperature heat energy in the incineration bin 217 can be transferred to the retort bin 216, to ensure that the incineration bin 217 and the retort bin 216 can all obtain enough heat energy to maintain normal operation. When the fuel in the incineration bin 217 is about to burn and finishes, the newly formed semi-coke fuel in the retort bin 216 can be put into the incineration bin 217 again, so that the combustion of the incineration bin 217 is maintained, and the high temperature heat energy formed by burning can act on the retort bin 216 again, and the garbage in the retort bin 216 is dry distilled, and with this circulation, as long as the supply of garbage is not interrupted, the work of the retort bin 216 and the incineration bin 217 just can form a circulation, and no additional heat energy needs to be applied. For the combustion of the incineration bin 217, the products formed have high temperature flue gas and ash, and the ash is placed on the tilting grate 213, and the high temperature flue gas then flows into the second combustion device 22 for subsequent processing. For ash, when it accumulates to a certain amount, the tilting grate 213 can be controlled to rotate and dump the ash into the burnout bin 218. The burnout bin 218 serves as a temporary storage for ash. The ash will gradually extinguish and cool down in the burnout bin 218 until the ash temperature is lower than 150°C, at which time the ash can be discharged.

[0027] It should be noted that the retort 216 is sealed by the energy storage grate 214 and the partition plate 212, so that an oxygen-free environment is maintained in the retort 216 to ensure that the garbage is retorted in an oxygen-free environment and no oxidation reaction occurs during the entire process. In this way, the generation of a large amount of highly toxic dioxins due to the incineration of domestic garbage in the retort 216 is eliminated from the source.

[0028] In some embodiments, see Figure 1 and Figure 2 The second combustion device 22 includes a second refractory wall assembly 221. The second refractory wall assembly 221 defines a cyclone combustion chamber 222 and a plurality of baffle chambers 223 that are connected in sequence. The cyclone combustion chamber 222 is connected to both the incineration chamber 217 and the retorting chamber 216, and the first baffle chamber 223 is connected to the cyclone combustion chamber 222. The flue gas generated by the combustion of fuel in the incineration chamber 217 and the combustible gas generated by the retorting chamber 216 both enter the cyclone combustion chamber 222. Under the action of the cyclone combustion chamber 222, the mixed gas is caused to rotate within the cyclone combustion chamber 222. During this rotation, the heavy, coarse particles of smoke and tar gas carried by the mixed gas are burned and, under the action of centrifugal force, are thrown toward the inner wall of the cyclone combustion chamber 222, where they collide and fall to the bottom of the cyclone combustion chamber 222. The lighter combustible gas, with its lower heat density, is pulled upward after hitting the bottom and then flows out of the top of the cyclone combustion chamber 222. Therefore, the cyclone combustion chamber 222 serves multiple functions, including fully redirecting the various gases into mixed flow, high-speed rotational combustion, and pre-dust and tar removal.

[0029] Furthermore, a first channel 2113 is provided in the first fire-resistant wall near the second fire-resistant wall group 221, and the second fire-resistant wall group 221 includes a first isolation wall 2211. The first isolation wall 2211 is arranged opposite to the first fire-resistant wall near the second fire-resistant wall group 221 to define a cyclone combustion chamber 222. The incineration chamber 217 and the distillation chamber 216 are both connected to the cyclone combustion chamber 222 through the first channel 2113. A second air supply mechanism 225 for introducing air is provided in the first channel 2113. The first channel 2113 is communicated with the inlet of the cyclone combustion chamber 222 and is tangent to the inlet surface of the cyclone combustion chamber, and the first channel 2113 is arranged in alignment with the first isolation wall 2211. By setting a second air supply mechanism 225 in the first channel 2113, air is supplied to the first channel 2113 to mix the combustible gas, flue gas and air. The air acts as a combustion aid to ensure that the combustible gas can be quickly ignited and continuously burned during the mixing process. The power of the air can also drive the mixed gas to flow toward the cyclone combustion chamber 222, increasing the flow rate, so that the mixed gas can better rotate in the cyclone combustion chamber 222.

[0030] It should be noted that the purpose of making the first channel 2113 tangential to the inlet surface of the cyclone combustion chamber 222 is to ensure that the mixed gas can rotate within the cyclone combustion chamber 222. In this embodiment, the cross-section of the tangential inlet section, i.e., the channel cross-section of the first channel 2113, is set relatively small, so that the mixed combustion airflow flowing through this channel reaches an initial velocity of 15-20 m / s, flowing into the cyclone combustion chamber 222 from the tangential direction of the inlet section. Due to the inertia of the velocity, the airflow enters the cylindrical section 2221 and is propelled forward along the side walls of the cylinder. Due to the circular structure of the cylindrical side walls, the combustion airflow changes from linear motion to circular motion. This circular motion forms an outer vortex and generates centrifugal force, causing dust particles and tar in the gas to adhere to form tar dust particles, which are then separated from the gas, thereby achieving the purpose of gas (flue gas) pre-purification. When the rotating downward outward-rotating gas reaches the cone, it moves closer to the center of the dust collector due to the contraction of the cone. When the combustion airflow reaches a certain position at the lower end of the cone, it reverses from the bottom to the top in the same direction of rotation from the middle of the cyclone separator, and continues to flow upward in a spiral, forming an inward-rotating combustion airflow. The inward-rotating airflow rotates upward until it reaches the top of the cylinder, and finally the combustion airflow is discharged from the outlet of the cyclone combustion chamber 222.

[0031] In some embodiments, an exhaust pipe 224 is provided at the top of the cyclone combustion chamber 222, and the pipe wall of the exhaust pipe 224 closes the gap defined between the first isolation wall 2211 and the first fire-resistant wall. The exhaust pipe 224 is arranged in alignment with the first channel 2113 and is coaxially connected to the cyclone combustion chamber 222. The diameter of the exhaust pipe 224 is smaller than the opening diameter of the cyclone combustion chamber 222. Preferably, the diameter of the exhaust pipe 224 is approximately one half of the opening diameter of the cyclone combustion chamber 222. By ensuring that when the mixed gas flows above the cyclone combustion chamber 222, the wall of the exhaust pipe 224 closes the gap defined between the first isolation wall 2211 and the first fire-resistant wall, so that the mixed gas will not flow directly into the deflection chamber 223. The exhaust pipe 224 and the first channel 2113 are aligned so that when the mixed gas flows to the opening of the cyclone combustion chamber 222, it will hit the wall of the exhaust pipe 224, and cooperate with the wall of the cylindrical section 2221 of the cyclone combustion chamber 222 to make the mixed gas rotate along the inner wall of the exhaust pipe 224 and the cyclone combustion chamber 222.

[0032] In some embodiments, multiple baffles 223 are vertically connected to form a serpentine path. This prolongs the residence time of the mixed gas within the baffles 223, ensuring complete combustion of the mixed gas and achieving the "3T+E" combustion conditions of full, high temperature. This includes a high temperature (T) exceeding 850°C, a residence time (T) exceeding 2.5 seconds, sufficient agitation and gasping during the combustion process (T), and adequate air flow (E). The second combustion device 22 ensures that the combustible gas from the first combustion device 21 fully meets the "3T+E" combustion conditions, thereby achieving ultra-high-temperature decomposition of toxic dioxins that may be present in the combustion flue gas, eliminating any hazards.

[0033] In some embodiments, see Figure 1 and Figure 2 The heat exchange and cooling device 23 includes a third fire-resistant wall group 231, an air heat exchanger 232, and a liquid heat exchanger 233. The third fire-resistant wall group 231 includes a plurality of enclosed third fire-resistant walls to define a heat exchange chamber 234. The air heat exchanger 232 and the liquid heat exchanger 233 are both disposed within the heat exchange chamber 234. The smoke inlet end of the air heat exchanger 232 is connected to the smoke outlet end of the second combustion device 22. The smoke outlet end of the air heat exchanger 232 is connected to the liquid heat exchanger 233 via a second channel 235, so that the smoke exhausted from the second combustion device 22 is sequentially heat exchanged and cooled through the air heat exchanger 232 and the liquid heat exchanger 233. For example, the high-temperature flue gas formed by the combustion of the mixed combustible gas in the second combustion device 22 finally flows out from the deflection chamber 223 at the end, and the high-temperature flue gas above 800°C flows into the heat exchange and cooling device 23. The flue gas flows into the upper tube end inlet of the air heat exchanger 232 and then flows out from the lower tube end outlet, and performs sufficient indirect gas-to-gas heat exchange with the cold air in the air heat exchanger 232, thereby reducing the flue gas temperature to 400-450°C. Subsequently, the flue gas cooled by the air heat exchanger 232 flows to the liquid heat exchanger 233 through the second channel 235 for gas-liquid heat exchange, thereby rapidly reducing the flue gas temperature to about 200°C, thereby effectively preventing the re-synthesis of dioxins in the flue gas.

[0034] Furthermore, the air heat exchanger 232 includes a first housing 2321, a flue gas heat exchange duct, and a blower 2322. The flue gas heat exchange duct is located within the first housing 2321 and comprises multiple first flue gas sub-ducts 2323 and multiple first U-shaped connecting pipes. Adjacent first flue gas sub-ducts 2323 are arranged in parallel and connected by a first U-shaped connecting pipe, forming a serpentine-like flue gas heat exchange duct. This maximizes the length of the flue gas circulation path within the limited space of the first housing 2321, ensuring sufficient heat exchange and cooling of the flue gas. The blower 2322 is embedded within the third fireproof wall assembly 231 and connected to the first housing 2321, ensuring that the cold air blown by the blower 2322 can fully contact the flue gas heat exchange duct, achieving indirect heat exchange between the flue gas and the cold air.

[0035] Further, see Figure 1 and Figure 3 A hot air channel 2311 is provided within the third fireproof wall. One end of hot air channel 2311 communicates with the outlet of air heat exchanger 232, specifically, with the outlet of first housing 2321, and the other end extends to first channel 2113. This extension can be achieved by providing a channel or pre-buried pipe within third and second fireproof wall groups 231 and 221, and then extending the channel or pre-buried pipe to first channel 2113. The cold air blown into first housing 2321 by blower 2322 exchanges heat with the flue gas, raising the air temperature to over 300°C and lowering the flue gas temperature to 400-450°C. The hot air finally flows into hot air channel 2311 and ultimately into first channel 2113, providing combustion-supporting air rich in heat energy for the mixed combustible gas within first channel 2113, accelerating combustion.

[0036] In some embodiments, a partition with a through hole is provided in the first box body 2321 to divide the first box body 2321 into two cavities connected with each other in an upper and lower manner. Each section of the first flue gas sub-duct 2323 passes through the through hole to be located in the two cavities. The blowing port of the blower 2322 is connected with the lower cavity, and the hot air channel 2311 is connected with the upper cavity. The blowing direction of the blower 2322 is perpendicular to the first flue gas sub-duct 2323, so that the cold air blown out by the blower 2322 can first flow through the lower cavity, and then flow through the upper cavity, and finally flow into the hot air channel 2311, so as to avoid the cold air from flowing chaotically without the constraint of the partition, affecting the heat exchange effect and the effect of hot air flowing into the hot air channel 2311.

[0037] In some embodiments, see Figure 1 and Figure 3The liquid heat exchanger 233 includes at least two heat exchange water tanks 2331. The two heat exchange water tanks 2331 are adjacent to each other and connected, with one heat exchange water tank 2331 located between the other heat exchange water tank 2331 and the air heat exchanger 232 and connected to the smoke outlet of the air heat exchanger 232. This allows the flue gas after air heat exchange to continue to enter the liquid heat exchanger 233 for further gas-liquid heat exchange, thereby improving the speed and effect of flue gas cooling and preventing the regeneration of dioxins in the flue gas.

[0038] The heat exchange water tank 2331 includes a second tank, multiple sections of second flue gas sub-ducts 2332, and multiple sections of second U-shaped connecting pipes. Both the multiple sections of second flue gas sub-ducts 2332 and the multiple sections of second U-shaped connecting pipes are located within the second tank, and two adjacent second flue gas sub-ducts 2332 are connected by the second U-shaped connecting pipes to form a serpentine path, extending the residence time of the flue gas within the second tank and improving the flue gas cooling effect. It should be noted that the second tanks of the two heat exchange water tanks 2331 are interconnected, and the second flue gas sub-duct 2332 at the end of one second tank is connected to the second flue gas sub-duct 2332 at the beginning of the other second tank, ensuring that flue gas can flow from one second tank to the other.

[0039] In some embodiments, since the temperature of the water after heat exchange rises from about 40°C to about 80°C, in order to enable the water cooling to be recycled, the vehicle-mounted mobile domestic waste dry distillation and incineration treatment system further includes a water cooling circulation device 26, the water inlet of the water cooling circulation device 26 is connected to the water outlet of the liquid heat exchanger 233, and the water outlet of the water cooling circulation device 26 is connected to the water inlet of the liquid heat exchanger 233, so that the liquid heated by heat exchange in the liquid heat exchanger 233 is cooled and returned to the liquid heat exchanger 233. By using the water cooling circulation device 26 to cool the hot water after heat exchange and returning the cooled water to the liquid heat exchanger 233, the water can be recycled, thereby improving the utilization rate of water and reducing the number of times water is added. This is especially effective in dealing with situations where there is no water source on the way during garbage transportation.

[0040] Furthermore, the water-cooling circulation device 26 includes a water pump 261, a water-cooled radiator 262, and a return pipe 263. The water-cooled radiator 262 is conventionally used and may utilize an aluminum finned tube bundle in combination with a fan or directly utilize the air flow during vehicle operation for heat dissipation. The details are omitted here. The two ends of the water pump 261 are connected to one of the second tanks and the water-cooled heat exchanger, respectively. The two ends of the return pipe 263 are connected to the other second tank and the water-cooled heat exchanger, respectively. The water pump 261 pumps hot water from the second tank to the water-cooled heat exchanger for water cooling. When the water temperature returns to approximately 40°C, it flows back to the second water tank through the return pipe 263.

[0041] In some embodiments, see Figure 1 and Figure 3 The purification and discharge device 24 is arranged in the space defined by the second fireproof wall group 221 and is separated from the cyclone combustion chamber 222 and the deflection chamber 223 to make full use of the internal space of the garbage disposal chamber 2. The purification and discharge device 24 includes a bag filter 241, an activated carbon adsorption box 242, an induced draft fan 243 and a chimney 244. The bag filter 241 is connected to the smoke outlet end of the heat exchange and cooling device 23 to receive the flue gas that has been cooled by water. The bag filter 241 intercepts and removes harmful smoke and dust in the flue gas. The bag filter 241 is a dust removal device commonly used in this field, and can be used in the form of filter bags or the like for dust removal. The activated carbon adsorption box 242 is connected to the air outlet side of the bag dust collector 241, so that the flue gas will enter the activated carbon adsorption box 242 after the dust is removed by the bag dust collector 241. In addition to being filled with activated carbon, the activated carbon adsorption box 242 can also be provided with an acid removal adsorbent. The activated carbon and the acid removal adsorbent adsorb the heavy metals and acid gases in the flue gas, so that the treated flue gas meets the emission requirements of the national standard "Standard for Pollution Control of Incineration of Municipal Waste GB18485-2014". The induced draft fan 243 has an air suction port and an air outlet, the air outlet is connected to the chimney 244, and the air suction port is connected to the air outlet end of the activated carbon adsorption box 242 to suck out the flue gas after adsorption and discharge it into the atmosphere through the chimney 244. Due to the suction effect of the induced draft fan 243, there is a negative pressure in the cyclone combustion chamber 222 and the deflection chamber, providing traction for the flow of flue gas. In other words, the induced draft fan 243 can provide flow power for the mixed gas in the first channel 2113, so that the mixed gas can maintain a certain flow rate to assist in forming a rotating motion, and the flue gas that has been rotated and burned in the rotating combustion chamber and has been preliminarily filtered can be pulled to flow to the deflection chamber 223.

[0042] In some embodiments, see Figure 1 The vehicle-mounted mobile domestic waste dry distillation incineration treatment system also includes a slag discharge device 27, a portion of which is built into the first refractory wall group 211, and the other portion is located at the bottom of the ember bin 218 and is connected to the ember bin 218. The portion of the slag discharge device 27 built into the first refractory wall group 211 can push the ash in the ember bin 218 to the portion of the slag discharge device 27 located at the bottom of the ember bin 218, so as to discharge the ash in the ember bin 218 out of the garbage treatment compartment.

[0043] Furthermore, the slag discharge device 27 includes a slag discharge hopper 271 and a slag pusher 272. The slag pusher 272 is arranged in the first refractory wall group 211 and the slag pushing end of the slag pusher 272 can extend into the ember bin 218. The slag discharge hopper 271 is arranged at the bottom of the ember bin 218 and is connected to the ember bin 218. When the slag pusher 272 is started, the ash in the ember bin 218 can be pushed into the slag discharge hopper 271, and then the ash in the slag discharge hopper 271 can be manually cleaned. It is understandable that the slag pusher 272 can be powered by a hydraulic cylinder or other driving devices such as a motor to push the slag pushing end of the slag pusher 272 to extend and retract. The slag pusher 272 is a prior art and will not be described in detail here, and there is no limitation on the power source for its driving.

[0044] It should be noted that a valve is provided at the connection point between the slag discharge hopper 271 and the burnout bin 218 to control the connection between the slag discharge hopper 271 and the burnout bin 218 .

[0045] In some embodiments, see Figure 1 and Figure 2 The vehicle-mounted mobile household waste dry distillation and incineration system also includes a loading device 25. Loading device 25 is located at the rear end of the waste treatment chamber 2 (the rear end of the waste treatment chamber 2 being the end away from the front end of the vehicle body 1). Loading device 25 is used to hold and transport the waste to the top of the first combustion device 21, where it is then poured into the first combustion device 21.

[0046] The loading device 25 comprises a hanging bucket 251, a lifting cylinder 252, a lifting rail 253, a connecting rod structure, a movable cover 254, and a lifting drive source 255. The hanging bucket 251 is detachably slidably mounted on the lifting rail 253. The driving end of the lifting drive source 255 is connected to the hanging bucket 251 to drive the hanging bucket 251 vertically up and down along the lifting rail 253. The lifting drive source 255 can be a linear motor, a hydraulic device, or the like. A movable cover 254 is hingedly connected to the side of the hanging bucket 251 facing the waste disposal chamber 2. The side of the movable cover 254 facing away from the hanging bucket 251 is hingedly connected to the top of the waste disposal chamber 2. When the hanging bucket 251 is at the bottom of the lifting rail 253, the movable cover 254 seals the feed partition drying chamber 215, thereby sealing the waste temporarily stored therein. This accelerates drying and prevents the external environment from affecting the waste within the feed partition drying chamber 215. When the hanging bucket 251 is raised by the lifting drive source 255, the movable cover 254 opens with the lifting of the hanging bucket 251. The movable cover 254 rotates about the hinged connection with the waste processing chamber 2. When the lifting drive source is a hydraulic device, the lifting cylinder 252 is connected to the hanging bucket 251 via a connecting rod structure. When the lifting cylinder 252 is raised, the connecting rod structure changes direction, driving the hanging bucket 251 to tilt toward the feed partition drying chamber 215, thereby realizing the automatic dumping of the garbage from the hanging bucket 251.

[0047] It should be noted that the structure of the loading device 25 is one of the commonly used devices in the garbage truck field, and is not the invention point of this application. It does not affect the technical problem solved by this technical solution, so it will not be described in detail.

[0048] In some embodiments, temperature sensors 28 may be provided in the incineration chamber 217 , the retorting chamber 216 , the baffle chamber 223 , the heat exchange and cooling device 23 , and the purification and exhaust device 24 to detect the temperature at each location.

[0049] In some embodiments, the vehicle-mounted mobile household waste retorting and incineration system also includes a monitoring and control cabinet (not shown). This cabinet can be located in the central control area of ​​the vehicle body 1, allowing the driver to control the operation of the waste treatment chamber 2 from within the cab. This monitoring and control cabinet serves as the central control center for controlling the electrical equipment in the waste treatment chamber 2, monitoring temperature changes within the furnace, and operating the hydraulic equipment. Operation buttons for all electrical devices and hydraulic control equipment in the waste treatment chamber 2 are located on the control cabinet panel. The control cabinet panel also features multiple temperature gauges, each electrically connected to a temperature sensor 28 to display the temperature detected by each temperature sensor 28, facilitating operator control.
