The appearances of the phrase that an embodiment in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive or alternative embodiments.

[0025] In order for those skilled in the art to better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0026] As Figures 1-5As shown, an equipped vehicle-mounted garbage cracking purification system comprises an equipped vehicle 100, which can be any existing vehicle with a cargo box. The equipped vehicle 100 is provided with a mounting platform 200, and the mounting platform 200 is provided with a crane 300, a generator 400 and a garbage cracking device. The crane 300 can be used to hoist each component of the equipped vehicle-mounted garbage cracking purification system, thereby facilitating assembly on the mounting 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, thereby making it suitable for use in places where it is inconvenient to connect to the mains, and improving versatility.

[0027] The garbage cracking device comprises a controller 1 provided with various control circuits and control software, and an automatic feeding machine 2, a cracking incinerator 3 and a flue gas purification device 4 fixedly installed on the mounting platform 200 and electrically connected to the controller 1. The automatic feeding machine 2 is connected to the cracking incinerator 3 and is used to pour 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 and discharge flue gas generated by the cracking incinerator 3. During operation, the operator pours the garbage to be treated onto the hopper of the automatic feeding machine 2, and by controlling the operation of the automatic feeding machine 2, the garbage can be poured into the cracking incinerator 3 for incineration. During incineration, the flue gas is discharged into the flue gas purification device 4, which purifies the flue gas and discharges it.

[0028] The equipped vehicle-mounted garbage cracking purification system mounts the garbage cracking device on the mounting platform 200 of the equipped vehicle 100, enabling mobile operation, high flexibility and convenience, and transporting the garbage cracking treatment system to any place where garbage treatment is required. It is suitable for garbage treatment requirements in different locations and environments. It saves manpower and resources for garbage transfer and effectively avoids secondary pollution caused by garbage transfer. The flue gas purification device 4 can purify the flue gas generated by garbage incineration, so that the exhaust gas can meet environmental protection standards, and has high market value and application prospect.

[0029] As shown in the accompanying drawings, Figure 2 , Figure 3As shown, the cracking incinerator 3 comprises a furnace body 31 which is fixedly installed on the installation platform 200 by bolts, and a heat insulation layer made of high-temperature-resistant material is arranged on the inner side wall of the furnace body 31, so as to reduce heat dissipation through the furnace wall and maintain a high-temperature environment inside the incinerator. At the same time, the heat insulation layer can also prevent the metal structure outside the furnace body 31 from being directly affected by high temperature, prevent the metal furnace body 31 from being deformed or damaged due to high temperature, and provide a safe working environment for workers. The upper end of the furnace body 31 is provided with a feeding hopper 32 which is connected with the automatic feeding machine 2; the automatic feeding machine 2 can dump garbage into the feeding hopper 32. The upper end of the feeding hopper 32 is provided with a cover plate 321 which is hingedly connected with the feeding hopper 32, and the feeding hopper 32 is provided with an opening mechanism 322 for driving the cover plate 321 to turn over. During operation, the cover plate 321 is turned over and opened by the opening mechanism 322, so that the automatic feeding machine 2 can dump garbage into the feeding hopper 32; after the garbage is dumped, the cover plate 321 is closed by the opening mechanism 322, so as to block the feeding hopper 32 and prevent the flue gas from being discharged from the feeding hopper 32, thereby protecting the surrounding environment.

[0030] The opening mechanism 322 can adopt a motor pulley structure and / or a cylinder structure, and the specific structure of the opening mechanism 322 is not limited in the present application, as long as it can drive the cover plate 321 to open and close.

[0031] The lower end of the furnace body 31 is provided with an ash collecting mechanism 33 for collecting and processing the ash left after the garbage is incinerated. The furnace body 31 is sequentially provided with a drying gasification chamber 34, a cracking gasification chamber 35, a carbonization cracking chamber 36 and a combustion chamber 37 from top to bottom, the drying gasification chamber 34 is connected with the feeding hopper 32 away from the cracking gasification chamber 35, and the combustion chamber 37 is connected with the ash collecting mechanism 33 away from the carbonization cracking chamber 36. The outer side of the furnace body 31 is provided with an oxygen supply device 5, the output end of the oxygen supply device 5 is connected with the carbonization cracking chamber 36, and the oxygen supply device 5 is used for conveying oxygen into the carbonization cracking chamber 36.

[0032] It should be noted that the drying gasification chamber 34 and the cracking gasification chamber 35 are both structures with the upper part connected with the lower part and the periphery closed; and the cracking gasification chamber 35 is a conical structure with the upper part smaller than the lower part. The carbonization cracking chamber 36 is connected with the upper part and the lower part, and the periphery side wall is composed of a plurality of porous plates, so that the oxygen supply device 5 can convey oxygen into the spring cracking chamber.

[0033] When the cracking incinerator 3 is working, waste incineration is carried out 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 several hundred degrees Celsius, but this place is closed and oxygen-free. The moisture in the waste coming from the feed hopper 32 will evaporate rapidly at this temperature and will be split into gas together with the harmful substances in the waste. The waste continues to fall into the cracking gasification chamber 35, which is still closed and oxygen-free. The waste cannot burn normally. The waste continues to fall into the carbonization cracking chamber 36, which is provided with holes on the side walls and has a high temperature. Oxygen is supplied by the oxygen supply device 5, so that the carbonization cracking chamber 36 is fully oxygenated, which can fully burn the waste. The materials formed by the intermediate oxygen-deficient combustion will be carbonized, and the carbonization will be more severe as it goes up. The solid waste that has not been completely burned falls onto the combustion chamber 37 below and continues to burn, and finally becomes ash that falls into the ash collecting mechanism 33, which is uniformly collected and treated.

[0034] As shown in Figure 2 、 Figure 3 In order to facilitate the supply of oxygen to the carbonization cracking chamber 36, the present embodiment is provided with an oxygen supply pipe 51 on the side wall of the furnace body 31 corresponding to the carbonization cracking chamber 36. The oxygen supply device 5 includes an oxygen supply machine 52 fixedly installed on the outer side wall of the furnace body 31, and the output end of the oxygen supply machine 52 is in communication with the oxygen supply pipe 51. The oxygen supply machine 52 can extract air and increase the oxygen content in the air, and then deliver the oxygen-rich air to the oxygen supply pipe 51, which flows 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 waste burning efficiency and make the waste burn fully in the carbonization cracking chamber 36.

[0035] As mentioned above, when the waste falls into the drying gasification chamber 34, the waste cannot burn normally. However, due to the high temperature, some substances in the waste will be gasified into combustible gas. In order to fully utilize this part of combustible gas, as shown in Figure 2 、 Figure 3As shown, the combustible gas injection mechanism 6 is also arranged 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 injection mechanism 6 includes a first air extractor 61 fixedly installed on the outer side wall of the furnace body 31, the input end of the first air extractor 61 is in communication with the drying gasification chamber 34, and the inner side wall around the furnace body 31 is provided with an injection gas pipe 62 at a position corresponding to the carbonization cracking chamber 36, the output end of the first air extractor 61 is in communication with the injection gas pipe 62, and the first air extractor 61 is used to extract the combustible gas in the drying gasification chamber 34 into the carbonization cracking chamber 36. During operation, after the garbage is poured into the drying gasification chamber 34, some combustible gas will be gasified due to the high temperature; the first air extractor 61 works to extract these combustible gases, which are then transported to the injection gas pipe 62 through the pipeline and sprayed into the carbonization cracking chamber 36 through the injection gas pipe 62; by supplementing combustible gas in the carbonization cracking chamber 36, the combustion temperature of the carbonization cracking chamber 36 can be improved, so that the garbage is fully burned in the carbonization cracking chamber 36, and the solid residue is reduced.

[0036] As shown in Figure 3 In order to further improve the incineration effect, a heat reflecting cover 38 is installed in the furnace body 31, the heat reflecting cover 38 is arranged between the drying gasification chamber 34 and the cracking gasification chamber 35, and a plurality of small holes for smoke to pass through are arranged on the heat reflecting cover 38. The heat reflecting cover 38 can keep the temperature in the furnace body 31, reducing heat loss; during operation, the light smoke in the furnace passes through the small holes on the heat reflecting cover 38, while the heavy smoke is blocked and falls into the furnace for further combustion, increasing the residence time of the smoke in the furnace and further decomposing the harmful substances in the smoke. At the same time, when the heat (infrared rays) generated by the garbage combustion is irradiated upward on the heat reflecting cover 38, the heat reflecting cover 38 will reflect it downward, reducing heat loss and improving the temperature in the furnace.

[0037] As shown in Figure 2 , Figure 3As shown, in order to reduce the emission of harmful substances in the flue gas, the flue gas circulating mechanism 7 is arranged on the furnace body 31, which is used to extract the flue dust generated by incineration to the lower part of the furnace body 31, so as to prolong the residence time of the flue gas in the furnace, and decompose the harmful substances (such as dioxin and chloride) in the flue gas by high temperature in the furnace. Specifically, the flue gas circulating mechanism 7 comprises a second air extractor 71 fixedly installed on the outer side wall of the furnace body 31, and an exhaust pipe 72 and an exhaust pipe 73 are arranged on the inner side wall of the furnace body 31 at positions corresponding to the cracking gasification chamber 35, the exhaust pipe 72 is located above the exhaust pipe 73, the exhaust pipe 72 is connected with the input end of the second air extractor 71, and the exhaust pipe 73 is connected with the output end of the second air extractor 71. By controlling the operation of the second air extractor 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 into the furnace body 31 through the exhaust pipe 73, so as to prolong the residence time of the flue gas in the furnace body 31; and the harmful substances in the flue gas can be more fully decomposed by the high temperature in the furnace.

[0038] As shown in Figure 2 , Figure 3 The ash collecting mechanism 33 comprises a conical ash hopper 331, which is sealingly connected with the lower end of the furnace body 31. The lime remaining in the garbage after the carbonization and cracking in the carbonization and cracking chamber 36 and the combustion chamber 37 will automatically fall onto the conical ash hopper 331. The lower end of the conical ash hopper 331 is provided with an ash discharging assembly, which is used to crush the lime and prolong the residence time of the lime in the furnace body 31, so that the lime is completely extinguished before being discharged.

[0039] Specifically, the ash discharging assembly comprises a material pipe 332, which is in communication with the conical ash hopper 331 and is obliquely arranged below the conical ash hopper 331, and the height of one end of the material pipe 332 in communication with the conical ash 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 discharging driving assembly 334 and an ash discharging port 335 are arranged on the material pipe 332. The output end of the ash discharging driving assembly 334 is connected with the spiral blade shaft 333, and is used to drive the spiral blade shaft 333 to rotate. During the ash discharging process, the ash discharging driving assembly 334 is controlled to work, so as to drive the spiral blade shaft 333 to rotate, crush the lime by the spiral blades on the spiral blade shaft 333, and push the lime to the ash discharging port 335, and finally fall from the ash discharging port 335 for collection. The lime is crushed by the spiral blade shaft 333, and stays in the material pipe 332 for a while, so that the lime can be completely extinguished, and the situation that the lime is still burning when being discharged from the ash discharging port 335 is reduced.

[0040] In this embodiment, the ash discharging driving assembly 334 is a motor driving device; in other embodiments, other structures or devices capable of driving the spiral blade shaft 333 to rotate can also be used.

[0041] The side wall of the furnace body 31 is provided with an observation window, and the observation window is provided with a closing door 39. The closing door 39 is connected with the furnace body 31 in an opening and closing mode, and is used for closing or opening the observation window. In use, the user can open the closing door 39, so as to observe the incineration condition in the furnace body 31, so as to know the incineration progress of the garbage in time.

[0042] As shown in Figure 1 , Figure 4 , Figure 5 The flue gas purification device 4 includes a flue gas exhaust assembly 41 and a flue gas purification tower 42. The flue gas exhaust assembly 41 is connected with the pyrolysis incinerator 3 and the flue gas purification tower 42 respectively, and is used for extracting the flue gas in the pyrolysis incinerator 3 to the flue gas purification tower 42. In the embodiment, the flue gas exhaust assembly 41 includes an air exhaust device. The input end of the air exhaust device is connected with the dry gasification chamber 34 in the furnace body 31 through a pipeline, and the output end of the air exhaust device is connected with the flue gas purification tower 42 through a pipeline.

[0043] The flue gas purification tower 42 includes a tower body 421. The tower body 421 is fixedly installed on the installation platform 200. The side wall of the tower body 421 is provided with an inlet 422. The upper end of the tower body 421 is provided with an exhaust port 423. The lower end of the tower body 421 is provided with a solid waste discharge port 424. The inlet 422 is connected with the flue gas exhaust assembly 41. The tower body 421 is provided with a purification assembly. In operation, the air exhaust device extracts the flue gas generated by combustion in the furnace body 31 to the flue gas purification tower 42. The flue gas flows into the tower body 421 through the inlet 422, and is purified through the purification assembly, and then is discharged through the exhaust port 423. The solid particles generated by the working of the purification assembly fall into the solid waste discharge port 424, and then are collected and treated uniformly.

[0044] In the embodiment, the purification assembly includes a plurality of cathode metal tubes 425 arranged in the tower body 421. Each cathode metal tube 425 is provided with an anode metal wire 426. In order to make the anode metal wire 426 straight, a counterweight 427 is arranged at the lower end of the anode metal wire 426. In operation, the cathode metal tube 425 and the anode metal wire 426 are electrified, so that a high-voltage electric field is generated between the anode metal wire 426 and the cathode metal tube 425. 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 in the flue gas collide with the gas ions, so that the dust particles are negatively charged. The dust particles move towards the anode metal wire 426, and are deposited on the anode metal wire 426 to form a block, which falls into the solid waste discharge port 424, and then is collected and treated manually. After the dust particles in the flue gas are removed, the gas meeting the emission requirements is discharged into the atmosphere through the exhaust port 423.

[0045] Working principle:

[0046] Firstly, the equipment vehicle 100 moves and installs the equipment vehicle garbage pyrolysis purification system to the preset garbage disposal site. Then, the controller 1 is powered on by connecting to the mains or generating electricity by the generator 400.

[0047] During the operation, the garbage is poured into the hopper of the automatic feeding machine 2, and the automatic feeding machine 2 is controlled to feed. At the same time, the cover opening mechanism 322 is controlled to open the cover plate 321, and the garbage is poured into the feeding hopper 32 through the automatic feeding machine 2. The garbage falls into the carbonization and cracking chamber 36 under the action of gravity and is burned.

[0048] During the garbage incineration and cracking process, the plasma oxygen supply machine 52, the first air extractor 61 and the second air extractor 71 are controlled to work at the same time.

[0049] The plasma oxygen supply machine 52 will transport oxygen-rich air into the oxygen supply pipe 51 in real time, and the oxygen-rich air will be injected into the carbonization and cracking chamber 36 through the oxygen supply pipe 51, so that the carbonization and cracking chamber 36 forms an oxygen-rich environment, which can improve the garbage burning efficiency and make the garbage burn fully in the carbonization and cracking chamber 36.

[0050] The first air extractor 61 works to extract the combustible gas in the dry gasification chamber 34, and then the combustible gas is transported to the injection gas pipe 62 through the pipeline and sprayed into the carbonization and cracking chamber 36 through the injection gas pipe 62. By supplementing combustible gas in the carbonization and cracking chamber 36, the burning temperature of the carbonization and cracking chamber 36 can be improved, so that the garbage burns fully in the carbonization and cracking chamber 36 and reduces the solid residue.

[0051] The second air extractor 71 works to 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 then re-enters the furnace body 31 through the flue gas discharge pipe 73, thereby prolonging the residence time of the flue gas in the furnace body 31, and more fully decomposing the harmful substances in the flue gas through the high temperature in the furnace.

[0052] The fully burned ash falls into the conical ash collector 331, and then falls into the material pipe 332. Then, the white ash is discharged through the ash discharge port 335 by controlling the ash discharge driving assembly 334 to work.

[0053] The flue gas generated during the combustion process is extracted into the flue gas purification tower 42 through the flue gas extraction assembly 41. The cathode metal pipe 425 and the anode metal wire 426 are powered on, so that when the flue gas passes through the cathode metal pipe 425, the dust particles are deposited on the anode metal wire 426, and finally form a block-shaped object which falls down to the solid waste discharge port 424. Then, the block-shaped object is collected and treated by manual operation. After the dust particles in the flue gas are removed, the gas meeting the emission requirements is discharged into the atmosphere through the exhaust port 423.

[0054] The above embodiment is the preferred embodiment of the present application, and is not intended to limit the specific implementation range of the present application. The scope of the present application includes but is not limited to the above embodiment. Any equivalent changes made according to the present application are within the protection scope of the present application.
