The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.

[0019] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0020] like Figure 1-5As shown, a vehicle-mounted garbage cracking and purification system includes a vehicle 100, and the vehicle 100 can be any existing type of vehicle with a cargo box. The vehicle 100 is provided with an installation platform 200, and a crane 300, a generator 400 and a garbage cracking device are installed on the installation platform 200. The crane 300 can be used to hoist the various components of the vehicle-mounted garbage cracking and purification system, so as to facilitate assembly on the installation platform 200, and can also be used to hoist garbage during garbage disposal. The generator 400 can be used to power the garbage cracking device, so that it is suitable for use in places where it is inconvenient to connect to the mains, thereby improving versatility.

[0021] The garbage cracking device includes a controller 1, in which various control circuits and control software are arranged. An automatic loader 2, a cracking incinerator 3 and a flue gas purification device 4 which are electrically connected to the controller 1 are fixedly installed on the mounting platform 200. The automatic loader 2 is connected to the cracking incinerator 3, and is used to dump the garbage to be incinerated into the cracking incinerator 3. The flue gas purification device 4 is connected to the cracking incinerator 3, and is used to purify the flue gas generated by the cracking incinerator 3 and discharge it. During operation, the operator dumps the garbage to be processed into the hopper of the automatic loader 2, and by controlling the automatic loader 2 to work, the garbage can be dumped into the cracking incinerator 3 for incineration; during the incineration process, the exhausted flue gas will flow into the flue gas purification device 4, and then the flue gas will be purified by the flue gas purification device 4 and discharged.

[0022] The equipment-type vehicle-mounted garbage cracking and purification system installs the garbage cracking device on the installation platform 200 of the equipment vehicle 100, which can realize mobile operation, has high flexibility and convenience, and can transport the garbage cracking and processing system to any place where garbage treatment is desired, and is suitable for garbage treatment needs in different locations and environments. It saves manpower and material resources for garbage transportation, and can also effectively avoid secondary pollution caused by garbage transportation. The flue gas generated by garbage incineration can be purified by the flue gas purification device 4, so that its exhaust gas can meet environmental protection standards, and has high market value and application prospects.

[0023] like Figure 2 , Figure 3As shown, the pyrolysis incinerator 3 includes a furnace body 31, which is fixedly mounted on the mounting platform 200 by bolts. A heat-insulating layer made of high-temperature resistant material is provided on the inner wall of the furnace body 31, so that the heat dissipated through the furnace wall can be reduced and the high-temperature environment inside the incinerator can be maintained. At the same time, by providing a heat-insulating layer, the external metal structure of the furnace body 31 can be protected from the direct effect of high temperature, so as to prevent the metal furnace body 31 from being deformed or damaged due to high temperature, and provide a safe working environment for the staff. A feed hopper 32 is installed at the upper end of the furnace body 31, and the feed hopper 32 is connected to the automatic feeder 2; the automatic feeder 2 can dump garbage into the feed hopper 32. A cover plate 321 is installed at the upper end of the feed hopper 32, and the cover plate 321 is connected to the feed hopper 32 in an opening and closing manner. The feed hopper 32 is provided with a cover opening mechanism 322 for driving the cover plate 321 to flip. During operation, the cover plate 321 is driven to flip open by the cover opening mechanism 322, so that the automatic loader 2 can dump the garbage into the feed hopper 32; after the garbage is dumped, the cover plate 321 is driven to close by the cover opening mechanism 322, thereby blocking the feed hopper 32 to prevent the incineration smoke from being discharged from the feed hopper 32 and protecting the surrounding environment.

[0024] The cover opening mechanism 322 may adopt a motor pulley structure and / or a cylinder structure, etc. The present invention does not limit its specific structure, and it only needs to ensure that it can drive the cover plate 321 to open and close.

[0025] An ash collecting mechanism 33 is installed at the lower end of the furnace body 31, and the ash collecting mechanism 33 is used to collect and process the ash left after the garbage is incinerated. A drying gasification chamber 34, a cracking gasification chamber 35, a carbonization cracking chamber 36 and a combustion chamber 37 are arranged in sequence from top to bottom in the furnace body 31. The side of the drying gasification chamber 34 away from the cracking gasification chamber 35 is connected to the feed hopper 32, and the side of the combustion chamber 37 away from the carbonization cracking chamber 36 is connected to the ash collecting mechanism 33. An oxygen supply device 5 is arranged on the outside of the furnace body 31, and the output end of the oxygen supply device 5 is connected to the carbonization cracking chamber 36. The oxygen supply device 5 is used to transport oxygen into the carbonization cracking chamber 36.

[0026] It should be noted that the drying gasification chamber 34 and the cracking gasification chamber 35 are both connected from top to bottom and closed on all sides; and the cracking gasification chamber 35 is a cone-shaped structure with a small top and a large bottom. The carbonization cracking chamber 36 is connected from top to bottom, and the surrounding side walls are composed of porous plates, so that the oxygen supply device 5 can transport oxygen into the spring cracking chamber.

[0027] When the pyrolysis incinerator 3 is working, garbage is incinerated in the furnace, so that the temperature in the furnace can reach thousands of degrees Celsius or even higher. At this time, the temperature of the drying gasification chamber 34 can also reach hundreds of degrees Celsius, but it is closed and oxygen-free here. The moisture in the garbage coming in from the feed hopper 32 will evaporate rapidly at this temperature and decompose into gas together with the harmful substances in the garbage. The garbage continues to fall into the pyrolysis gasification chamber 35, which is still closed and oxygen-free here, and the garbage cannot be burned normally. The garbage continues to fall into the carbonization cracking chamber 36. The side walls of the carbonization cracking chamber 36 have holes, and the temperature is high. Oxygen is supplied by the oxygen supply device 5, so that the carbonization cracking chamber 36 is fully supplied with oxygen, and the garbage can be fully burned. The materials formed by the lack of oxygen in the middle will be carbonized, and the higher the carbonization, the more serious it is. The solid that has not been completely burned falls to the combustion chamber 37 below and continues to burn, and finally turns into gray ash and falls to the ash collecting mechanism 33, and is uniformly collected and processed by the ash collecting mechanism 33.

[0028] like Figure 2 , Figure 3 As shown, in order to facilitate the supply of oxygen to the carbonization cracking chamber 36, in this embodiment, oxygen supply pipes 51 are respectively provided at positions corresponding to the carbonization cracking chamber 36 on the four side walls of the furnace body 31. The oxygen supply device 5 includes an ion oxygen supply machine 52 fixedly mounted on the outer side wall of the furnace body 31, and the output end of the plasma oxygen supply machine 52 is connected to the oxygen supply pipe 51. The plasma oxygen supply machine 52 can extract air and increase the oxygen content in the air, and then transport the oxygen-enriched air to the oxygen supply pipe 51, and the oxygen-enriched air flows into the carbonization cracking chamber 36 through the oxygen supply pipe 51, so that the carbonization cracking chamber 36 forms an oxygen-enriched environment, which can improve the garbage combustion efficiency and enable the garbage to be fully burned in the carbonization cracking chamber 36.

[0029] As mentioned above, when the garbage falls into the drying and gasification chamber 34, the garbage cannot burn normally. However, due to the high temperature, some substances in the garbage will be gasified into combustible gas. In order to make full use of this part of combustible gas, Figure 2 , Figure 3As shown, a combustible gas ejection mechanism 6 is also provided on the furnace body 31, which is used to extract the combustible gas in the drying gasification chamber 34 into the carbonization cracking chamber 36 for combustion. Specifically, the combustible gas ejection mechanism 6 includes a first exhaust fan 61, which is fixedly mounted on the outer wall of the furnace body 31, the input end of the first exhaust fan 61 is connected to the drying gasification chamber 34, and ejection gas pipes 62 are respectively provided at positions corresponding to the carbonization cracking chamber 36 on the inner side walls around the furnace body 31, and the output end of the first exhaust fan 61 is connected to the ejection gas pipe 62, and the first exhaust fan 61 is used to extract the combustible gas in the drying gasification chamber 34 into the carbonization cracking chamber 36. During the operation, after the garbage is dumped into the drying gasification chamber 34, some combustibles in the garbage will be gasified into combustible gas due to the high temperature; the first exhaust fan 61 will extract these combustible gases, and then transport them to the induced gas pipe 62 through the pipeline, and then spray them into the carbonization cracking chamber 36 through the induced gas pipe 62; by adding combustible gas in the carbonization cracking chamber 36, the combustion temperature of the carbonization cracking chamber 36 can be increased, so that the garbage can be fully burned in the carbonization cracking chamber 36, reducing solid residue.

[0030] like Figure 3 As shown, in order to further improve the incineration effect, a heat reflection cover 38 is installed in the furnace body 31. The heat reflection cover 38 is arranged between the drying gasification chamber 34 and the cracking gasification chamber 35. The heat reflection cover 38 is provided with a plurality of small holes for the flue gas to pass through. The heat reflection cover 38 can keep the temperature in the furnace body 31 warm and reduce heat loss. During the operation, the light flue gas in the furnace passes through the small holes on the heat reflection cover 38, while the heavy smoke is blocked and falls into the furnace to continue burning, increasing the residence time of the flue gas in the furnace and further decomposing the harmful substances in the flue gas. At the same time, when the heat (infrared rays) generated by the burning of garbage irradiates upward on the heat reflection cover 38, the heat reflection cover 38 will reflect it downward and radiate it, reducing heat loss and increasing the temperature in the furnace.

[0031] like Figure 2 , Figure 3As shown, in order to reduce the discharge of harmful substances in the flue gas, a flue gas circulation mechanism 7 is provided on the furnace body 31. The flue gas circulation mechanism 7 is used to re-extract the smoke generated by incineration to the bottom of the furnace body 31, increase the residence time of the flue gas in the furnace, and fully decompose the harmful substances (such as dioxins, chlorides, etc.) in the flue gas through the high temperature in the furnace. Specifically, the flue gas circulation mechanism 7 includes a second exhaust fan 71, which is fixedly installed on the outer wall of the furnace body 31. A smoke extraction pipe 72 and a smoke exhaust pipe 73 are respectively provided at the corresponding positions of the pyrolysis gasification chamber 35 on the inner side walls around the furnace body 31. The smoke extraction pipe 72 is located above the smoke exhaust pipe 73. The smoke extraction pipe 72 is connected to the input end of the second exhaust fan 71, and the smoke exhaust pipe 73 is connected to the output end of the second exhaust fan 71. By controlling the operation of the second exhaust fan 71, the flue gas in the upper part of the cracking gasification chamber 35 can be extracted to the lower part of the cracking gasification chamber 35, and then sent back into the furnace body 31 through the exhaust pipe 73, thereby extending the residence time of the flue gas in the furnace body 31; thereby, the harmful substances in the flue gas can be more fully decomposed by the high temperature in the furnace.

[0032] like Figure 2 , Figure 3 As shown, the ash collecting mechanism 33 includes a conical ash collecting hopper 331, which is sealed and connected to the lower end of the furnace body 31. The white ash remaining in the garbage after being burned in the carbonization cracking chamber 36 and the combustion chamber 37 will automatically fall into the conical ash collecting hopper 331. The lower end of the conical ash collecting hopper 331 is provided with an ash discharge assembly, which is used to break up the white ash and also prolong the residence time of the white ash on the furnace body 31, so that it is completely extinguished before being discharged.

[0033] Specifically, the ash discharge assembly includes a material pipe 332, which is connected to the conical ash collecting hopper 331. The material pipe 332 is inclined and arranged below the conical ash collecting hopper 331, and the height of one end of the material pipe 332 connected to the conical ash collecting hopper 331 is lower than the height of the other end. A spiral blade shaft 333 is arranged in the material pipe 332, and an ash discharge drive assembly 334 and an ash discharge port 335 are arranged on the material pipe 332. The output end of the ash discharge drive assembly 334 is connected to the spiral blade shaft 333 to drive the spiral blade shaft 333 to rotate. In the ash discharge process, by controlling the ash discharge drive assembly 334 to work, the spiral blade shaft 333 can be driven to rotate, and the spiral blades on the spiral blade shaft 333 can be used to break the white ash, and at the same time, the white ash can be pushed to the ash discharge port 335, and finally fall from the ash discharge port 335 for collection. The spiral blade shaft 333 is used to break up the white ash, and allows it to stay on the material pipe 332 for a while, so that it can be completely extinguished, thereby reducing the possibility of the white ash discharged from the ash discharge port 335 still being burned.

[0034] In this embodiment, the ash discharge driving component 334 is a motor driving device; in other embodiments, other structures or devices that can drive the spiral blade shaft 333 to rotate may also be used.

[0035] An observation window is provided on the side wall of the furnace body 31, and a closing door 39 is provided on the observation window; the closing door 39 is connected to the furnace body 31 for closing or opening the observation window. During use, the user can open the closing door 39 to observe the incineration situation in the furnace body 31, so as to understand the incineration progress of the garbage in a timely manner.

[0036] like Figure 1 , Figure 4 , Figure 5 As shown, the smoke purification device 4 includes a smoke exhaust component 41 and a smoke purification tower 42. The smoke exhaust component 41 is connected to the pyrolysis incinerator 3 and the smoke purification tower 42 respectively. The smoke exhaust component 41 is used to extract the smoke in the pyrolysis incinerator 3 to the smoke purification tower 42. In this embodiment, the smoke exhaust component 41 includes an exhaust device, the input end of the exhaust device is connected to the drying gasification chamber 34 in the furnace body 31 through a pipeline, and the output end of the exhaust device is connected to the smoke purification tower 42 through a pipeline.

[0037] The flue gas purification tower 42 includes a tower body 421, which is fixedly mounted on the mounting platform 200. A smoke inlet 422 is provided on the side wall of the tower body 421, an exhaust port 423 is provided at the upper end of the tower body 421, and a solid waste outlet 424 is provided at the lower end of the tower body 421. The smoke inlet 422 is connected to the smoke exhaust component 41, and a purification component is provided in the tower body 421. During operation, the exhaust device will extract the smoke generated by the combustion in the furnace body 31 into the flue gas purification tower 42; it will flow into the tower body 421 through the smoke inlet 422, and then be purified by the purification component and discharged through the exhaust port 423; the solid particles generated by the purification component will fall to the solid waste outlet 424, and then be collected and processed uniformly.

[0038] In this embodiment, the purification component includes a plurality of cathode metal tubes 425 arranged in the tower body 421, and each cathode metal tube 425 is provided with an anode metal wire 426; in order to allow the anode metal wire 426 to be straightened, a counterweight 427 is provided at the lower end of the anode metal wire 426. During operation, the cathode metal tube 425 and the anode metal wire 426 are energized, so that the anode metal wire 426 and the cathode metal tube 425 generate a high voltage electric field, and the gas in the cathode metal tube 425 is ionized to generate negatively charged gas ions. When the flue gas passes through the cathode metal tube 425, the dust particles therein collide with the gas ions, so that the dust particles are negatively charged, and the dust particles move toward the anode metal wire 426, and the dust particles are deposited on the anode metal wire 426, and finally form a block and fall down to the solid waste discharge port 424, and then are collected and processed manually; after the dust particles in the flue gas are removed, the gas that meets the emission requirements is discharged into the atmosphere through the exhaust port 423.

[0039] Working principle: First, the equipment-type vehicle-mounted garbage cracking and purification system is moved and installed to a preset garbage disposal site by the equipment vehicle 100. Then, the controller 1 is powered on by connecting to an external mains supply or by generating electricity through the generator 400.

[0040] During the operation, the garbage is dumped into the hopper of the automatic loader 2, and the automatic loader 2 is controlled to load the garbage; at the same time, the cover opening mechanism 322 is controlled to open the cover plate 321, and the garbage is dumped into the feed hopper 32 through the automatic loader 2. Under the action of gravity, the garbage will fall into the carbonization cracking chamber 36 for combustion.

[0041] During the process of garbage incineration and cracking, the plasma oxygen supply machine 52, the first exhaust fan 61 and the second exhaust fan 71 are controlled to work simultaneously.

[0042] The plasma oxygen supply machine 52 will deliver oxygen-rich air to the oxygen supply pipe 51 in real time, and inject the oxygen-rich air into the carbonization cracking chamber 36 through the oxygen supply pipe 51, so that the carbonization cracking chamber 36 forms an oxygen-rich environment, which can improve the garbage combustion efficiency and enable the garbage to burn fully in the carbonization cracking chamber 36.

[0043] When the first exhaust fan 61 is working, the combustible gas in the drying gasification chamber 34 is extracted, and then the combustible gas is transported to the induced gas pipe 62 through the pipeline, and then injected into the carbonization cracking chamber 36 through the induced gas pipe 62; by adding combustible gas in the carbonization cracking chamber 36, the combustion temperature of the carbonization cracking chamber 36 can be increased, so that the garbage can be fully burned in the carbonization cracking chamber 36, reducing solid residue.

[0044] The second exhaust fan 71 can extract the flue gas from the upper part of the cracking gasification chamber 35 to the lower part of the cracking gasification chamber 35, and send it back into the furnace body 31 through the exhaust pipe 73, thereby extending the residence time of the flue gas in the furnace body 31; thereby, the harmful substances in the flue gas can be more fully decomposed by the high temperature in the furnace.

[0045] The fully burned ash will fall into the conical ash collecting hopper 331 and then fall into the material pipe 332 . Then, the ash discharge driving component 334 is controlled to work and the white ash is discharged through the ash discharge port 335 .

[0046] The flue gas generated during the combustion process will be drawn into the flue gas purification tower 42 through the smoke exhaust component 41. By energizing the cathode metal tube 425 and the anode metal wire 426, when the flue gas passes through the cathode metal tube 425, the dust particles are deposited on the anode metal wire 426, and eventually form lumps that fall down to the solid waste discharge port 424, and are then collected and processed manually; after the dust particles in the flue gas are removed, the gas that meets the emission requirements is discharged into the atmosphere through the exhaust port 423.

[0047] The above-mentioned specific implementation is a preferred implementation of the present invention, and is not intended to limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to this specific implementation. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
