Description

Technical Field

[0001] This invention relates to the field of environmental protection technology, specifically to a rural and pastoral waste treatment device integrated on a mobile platform. Background Technology

[0002] Waste management refers to the process of collecting, transporting, transforming, and ultimately disposing of solid waste generated in daily life or production, aiming to reduce, render harmless, and recycle waste. Traditional centralized waste management models (such as landfills and large-scale incineration plants) rely on well-established collection and long-distance transportation systems, which are costly to build and operate. For my country's vast rural and pastoral areas, the dispersed settlements, low population density, and limited road conditions make it extremely difficult to establish and maintain such a system. This results in large amounts of domestic waste being indiscriminately dumped, landfilled, or simply incinerated, causing serious soil, water, and air pollution. In particular, open burning produces highly toxic substances such as dioxins, which also pose a fire risk on grasslands, directly threatening the ecological environment and human health.

[0003] Therefore, the urgent technical problem to be solved in this field is: how to provide a waste treatment technology and device that can adapt to the characteristics of remote, dispersed areas with high mobility requirements and weak infrastructure, and ensure efficient and clean combustion when treating waste on-site, especially effectively curbing the emission of harmful pollutants such as dioxins and preventing grassland fires. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rural and pastoral waste treatment device integrated on a mobile platform, solving the technical problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a rural and pastoral waste treatment device integrated on a mobile platform, comprising a mobile carrier, an incinerator body, a flue gas purification system, and a flue gas recirculation system; The mobile vehicle is an agricultural diesel flatbed truck, used to carry and transport the equipment; The incinerator body is a vertical cylindrical structure. Its inner cavity consists of an ash collection bin, a grate, and a waste combustion zone from bottom to top. The inner liner of the incinerator body is lined with a high-temperature resistant inner lining material, and the bottom of the incinerator body is lined with a high-temperature resistant bottom layer material. The top of the incinerator body is equipped with a double-layer furnace cover structure. The upper furnace cover has a first circular opening in the center, and the lower furnace cover has a second circular opening in the center. The cylindrical openings are connected to form an annular flue gas inlet space between the two, which is separated from the flue gas inlet residence area. The vertically connected cylindrical openings together form a cylindrical waste and air oxygen inlet. The lower furnace cover has multiple evenly distributed air holes around the cylindrical outer wall of the inlet. The air holes connect the flue gas inlet residence area and the waste combustion zone. The flue gas purification system is connected to the flue gas outlet at the bottom of the incinerator body through a flue gas connection pipe. Inside the flue gas purification system, a dust collector, a multi-layer dry filter unit and a high-efficiency micro dust filter are arranged in sequence along the flue gas flow direction. The flue gas circulation system includes a high-temperature resistant circulating fan. The air inlet of the high-temperature resistant circulating fan is connected to the clean gas outlet of the flue gas purification system, and its air outlet is connected to the flue gas inlet residence area at the top of the incinerator body through a flue gas return pipe. The incinerator also includes an automatic feeding mechanism, which includes a lifting frame, a power-driven hoist, an electrical control box, and an on-board battery that supplies power to it, for lifting the waste to the waste and air oxygen inlet and feeding it into the incinerator.

[0006] In some embodiments, the lower part of the side wall of the incinerator body is provided with a slag removal port for removing large impurities and an ash discharge port for discharging combustion ash.

[0007] In some embodiments, the housing of the flue gas purification system is provided with multiple inspection doors and ash removal ports corresponding to each purification unit, including ash removal ports corresponding to dust collectors, inspection and filter media replacement ports corresponding to multi-layer dry filter units, and filter element cleaning ports corresponding to high-efficiency particulate filters.

[0008] In some embodiments, the high-temperature resistant circulating fan is equipped with a rain cover and is connected to the vehicle battery via a separate power supply cable.

[0009] In some embodiments, the flue gas connection pipe and the flue gas return pipe are connected to each equipment interface by a detachable flange joint.

[0010] In some embodiments, the access door of the flue gas purification system is equipped with an easy-to-operate wheel-type locking handle.

[0011] In some embodiments, the incinerator body is fixed to the cargo box of the agricultural diesel flatbed truck by a steel structure support.

[0012] In some embodiments, the incinerator body also includes a safety ladder for operators.

[0013] This invention provides a method for treating municipal solid waste using the aforementioned device, characterized by comprising the following steps: S1. Domestic waste is fed into the waste combustion zone of the incinerator body through the waste and air oxygen inlet via the automatic feeding mechanism; S2. Ignite the waste. When the waste is put into the furnace, the power supply line is turned on and the high-temperature circulating fan is started. Under the negative pressure of the fan, the high-temperature flue gas generated by combustion passes through the grate and ash bin in sequence, and enters the flue gas purification system through the flue gas connection pipe. S3. The flue gas is sequentially purified by dust removal and multi-stage filtration in the flue gas purification system, and then pressurized by the high-temperature resistant circulating fan and transported to the flue gas furnace residence area through the flue gas return pipeline; S4. After being buffered in the flue gas inlet residence area, the purified high-temperature flue gas is injected into the waste combustion zone in the form of a jet through the air hole, and mixes with the fresh air and waste entering through the waste and air oxygen inlet, so as to realize the secondary combustion of flue gas and the reuse of heat energy. At the same time, the combustible components in the flue gas are completely decomposed at high temperature.

[0014] This invention provides a rural and pastoral waste treatment device integrated into a mobile platform. By integrating the incinerator, flue gas purification system, and circulation system into an agricultural flatbed truck, this invention achieves mobile deployment of waste treatment, solving the fundamental problems of difficult waste collection and transportation and high construction costs of treatment facilities in remote areas. Its core technology lies in closed-loop flue gas circulation and re-combustion: the flue gas generated from incineration undergoes multi-stage physical purification, is pressurized by a high-temperature resistant circulating fan, and then re-injected into the high-temperature waste combustion zone through the flue gas inlet residence area at the top of the furnace and annular vents. This process allows the flue gas containing unburned combustibles and pollutants such as dioxins to undergo secondary pyrolysis and oxidation in a high-temperature environment above 850℃, achieving near-zero emissions of pollutants. Simultaneously, the reuse of high-temperature flue gas significantly improves the thermal efficiency within the furnace, promoting complete combustion of waste. The entire device features a high degree of automation, low energy consumption, and stable ash residue after incineration, enabling resource utilization. This provides an economical, efficient, and environmentally friendly decentralized waste treatment solution for rural and pastoral areas. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1 The present invention provides a technical solution: a rural and pastoral waste treatment device integrated on a mobile platform, including a mobile carrier, an incinerator body, a flue gas purification system and a flue gas circulation system; Mobile vehicle 34 is an agricultural diesel flatbed truck used for carrying and transporting equipment.

[0019] The incinerator body 1 is a vertical cylindrical structure. Its inner cavity consists of an ash collection bin 14, a grate 13, and a waste combustion zone 7 from bottom to top. The inner liner of the furnace body is lined with a high-temperature resistant inner lining material 29, and the bottom of the furnace body is lined with a high-temperature resistant bottom layer material 31. The top of the furnace body is equipped with a double-layer furnace cover structure. The upper furnace cover has a first circular opening 2 in the center, and the lower furnace cover has a second circular opening 3 in the center. The space between the two forms an annular flue gas inlet residence area 5. The vertically connected circular openings together form a cylindrical waste and air oxygen inlet 4. The lower furnace cover has multiple evenly distributed air holes 6 around the cylindrical outer wall of the inlet. The air holes 6 connect the flue gas inlet residence area 5 and the waste combustion zone 7.

[0020] The flue gas purification system 16 is connected to the flue gas outlet at the bottom of the incinerator body 1 through the flue gas connection pipe 15. Inside the flue gas purification system 16, a dust collector 17, a multi-layer dry filter unit 18 and a high-efficiency micro dust filter 19 are arranged in sequence along the flue gas flow direction. The dust collector 17 is a cyclone or multi-tube dust collector.

[0021] The flue gas circulation system includes a high-temperature resistant circulating fan 11. The air inlet of the high-temperature resistant circulating fan 11 is connected to the clean gas outlet of the flue gas purification system 16, and its outlet is connected to the flue gas inlet residence area 5 at the top of the incinerator body 1 through the flue gas return pipe 12.

[0022] The incinerator body 1 also includes an automatic feeding mechanism, which includes a lifting frame 8, a power-driven hoist 9, an electrical control box 10, and an on-board battery 33 that supplies power to it, for lifting the waste to the waste and air oxygen inlet 4 and feeding it into the incinerator body 1.

[0023] In some embodiments, the lower part of the side wall of the incinerator body 1 is provided with a slag removal port 20 for removing large impurities and an ash discharge port 21 for discharging combustion ash.

[0024] This design ensures that the non-combustible materials and combustion residues accumulated inside the furnace can be easily and regularly cleaned, avoiding furnace blockage and reduced combustion efficiency, ensuring continuous and stable operation of the equipment, and extending the service life of the equipment.

[0025] In some embodiments, the housing of the flue gas purification system 16 is provided with multiple inspection doors and dust removal ports corresponding to each purification unit, including a soot removal port 22 and a dust cleaning port 23 corresponding to the dust collector 17, an inspection and filter media replacement port 24 corresponding to the multi-layer dry filter unit 18, and a filter element cleaning port 25 corresponding to the high-efficiency particulate filter 19.

[0026] This structure provides a convenient channel for daily maintenance, cleaning, and replacement of key components of the purification system, enabling the system to maintain high purification performance over a long period of time, preventing pollutant escape due to filter media clogging or failure, and ensuring the reliability of the overall treatment effect.

[0027] In some embodiments, the high-temperature resistant circulating fan 11 is equipped with a rain cover 27 and is connected to the vehicle battery 33 via a separate power supply cable 26.

[0028] The rain cover effectively protects critical power equipment from outdoor wind and rain erosion, improving the equipment's all-weather operation capability and durability; the independent power supply line ensures the dedicated and stable power supply to the wind turbine, avoids circuit interference, and improves the safety and reliability of system operation.

[0029] In some embodiments, the flue gas connection pipe 15 and the flue gas return pipe 12 are connected to each equipment interface by a detachable flange joint 28.

[0030] This connection method facilitates rapid on-site assembly, disassembly, and subsequent maintenance of the equipment, improving the flexibility of equipment deployment. At the same time, it ensures the airtightness of the pipeline connection, prevents flue gas leakage, and maintains the stability of the negative pressure environment inside the system.

[0031] In some embodiments, the access door of the flue gas purification system 16 is equipped with an easy-to-operate wheel-type locking handle 30.

[0032] This design makes opening and closing the sealed access door easier and faster, significantly improving the efficiency of daily maintenance work, and ensuring a good seal when the door is closed to prevent the leakage of harmful gases.

[0033] In some embodiments, the incinerator body 1 is fixed to the cargo box of the agricultural diesel flatbed truck 34 by a steel structure bracket 36.

[0034] The robust steel structure support provides stable support for the heavy furnace body, effectively dispersing vibrations and stresses during operation, ensuring the structural safety and overall stability of the equipment during vehicle movement and operation, and preventing equipment damage or loosening of connections due to bumps.

[0035] In some embodiments, the incinerator body (1) also includes a safety ladder 35 for use by operators.

[0036] This invention provides a method for treating municipal solid waste using the aforementioned device, characterized by comprising the following steps: S1. Domestic waste is fed into the waste combustion zone 7 of the incinerator body 1 through the waste and air oxygen inlet 4 via an automatic feeding mechanism.

[0037] S2. Ignite the waste. When the waste is put into the furnace, turn on the power supply line and start the high-temperature circulating fan 11. Under the negative pressure of the fan, the high-temperature flue gas generated by the combustion of the waste and the oxygen inlet 4 passes through the grate 13 and the ash bin 14 in sequence, and enters the flue gas purification system 16 through the flue gas connection pipe 15.

[0038] S3. After being purified by dust removal and multi-stage filtration in the flue gas purification system 16, the flue gas is pressurized by the high-temperature resistant circulating fan 11 and transported to the flue gas entry and residence area 5 through the flue gas return pipe 12.

[0039] S4. After being buffered in the flue gas residence zone 5, the purified high-temperature flue gas is injected into the waste combustion zone 7 in the form of a jet through the air hole 6. It mixes with the fresh air and waste entering through the waste and air oxygen inlet 4, realizing the secondary combustion of flue gas and the reuse of heat energy. At the same time, the combustible components in the flue gas are completely decomposed at high temperature.

[0040] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0041] Example: The device in this example is mounted on an agricultural diesel flatbed truck 34, achieving high mobility and making it particularly suitable for sparsely populated rural and pastoral areas and temporary garbage collection points. The core of the device consists of an incinerator body 1 and a flue gas purification system 16 closely connected to it, which are fixed together by a flue gas duct connected by a flange 28. The incinerator body 1 is a vertical cylindrical structure, firmly fixed to the truck by a furnace body support frame 36. Its inner wall is entirely coated with a high-temperature resistant material 29, and the bottom is covered with a high-temperature resistant layer 31 to withstand the continuous high temperature of garbage incineration. The interior of the furnace body is mainly divided into a garbage combustion zone 7, a grate 13, and an ash collection bin 14 from top to bottom. The top of the furnace body is designed with a unique double-layer cover structure: the first circular opening 2 and the second circular opening 3 correspond to each other vertically to form a through-flow inlet 4 for waste and oxygen; the annular sealed space between the two covers constitutes the key flue gas entry and residence area 5; on the second cover 3, multiple small circular holes 6 are opened around the cylinder wall surrounding the waste and oxygen inlet 4, serving as channels for purified flue gas to return to the combustion chamber.

[0042] The flue gas purification system 16 of the device is located on one side of the furnace body and has a compact tower structure. It is connected to the furnace body ash collection bin 14 through the flue gas entry channel 15. Its internal purification process strictly follows the well-known physical filtration principle of coarse to fine: the flue gas first enters the multi-tube dust collector 17 at the bottom for primary centrifugal sedimentation dust removal, then rises and passes through the multi-layer filter device 18 to adsorb and intercept finer particles, and finally passes through the micro-dust filter device 19 to complete deep purification. The system is equipped with multiple maintenance ports, including an ash removal port 22, a dust cleaning port 23, a multi-layer filter flue gas device replacement port 24, and a flue gas micro-dust filter cleaning port 25. The maintenance door is equipped with a wheeled handle 30 for opening and closing the furnace body purification system equipment, which facilitates regular cleaning and replacement of filter media to ensure purification efficiency.

[0043] The power and operation procedures of the device are as follows: During operation, the operator can reach the operating platform via ladder 35. Household waste is placed on the waste bin lifting frame 8. The waste lifting and furnace initiator 9 is started, powered by the vehicle battery 33 via power supply line 32, and controlled by the battery power supply switch controller 10. This lifts the waste and places it into the waste and air oxygen inlet 4. After ignition, the high-temperature resistant flue gas circulation blower 11 is started. It is powered by the high-temperature resistant flue gas circulation blower power supply line 26 and equipped with a high-temperature resistant flue gas circulation blower rain cap 27. This blower is the core of the entire system's fluid dynamics. It generates negative pressure, drawing the high-temperature flue gas generated by combustion in the furnace from the lower part of the waste combustion zone 7 through the grate 13 gaps into the ash collection bin 14, and then forcing the flue gas into the flue gas purification system 16 to complete the aforementioned three-stage purification. The purified flue gas is pressurized by a blower and pumped into the flue gas inlet residence area 5 at the top through the flue gas inlet channel 12. After a short stay and even mixing, it is sprayed back to the high-temperature waste combustion zone 7 through multiple small round holes 6 at a certain speed.

[0044] This process constitutes a closed-loop flue gas recirculation, which is the key to this invention. The injected high-temperature purified flue gas not only carries a large amount of heat for reuse, improving the thermal efficiency of the furnace and promoting the rapid and complete combustion of waste, but more importantly, the incompletely burned combustible components contained therein, such as carbon monoxide and hydrocarbons, as well as the reintroduced oxygen, are re-burned in the high-temperature environment above 850°C in the waste combustion zone 7. This achieves deep thermal destruction of harmful substances, including dioxins, within the furnace, rather than simply transferring pollutants to the atmosphere. The ash produced by combustion falls from the grate 13 into the ash collection bin 14 and is eventually discharged through the ash removal outlet 21; non-combustible materials can be cleaned through the non-combustible waste removal outlet 20. The entire workflow requires no addition of any chemical combustion aids or treatment agents, achieving on-site, harmless, and reduced-volume treatment of waste, and there is no odor leakage during operation, meeting environmental protection requirements. The on-board battery 33 is powered by the engine of the agricultural diesel flatbed truck 34 when the vehicle is stopped, enabling the device to operate independently in remote areas without an external power grid.
