The feeding mechanism 2 is connected to the pyrolysis incinerator 3. The feeding mechanism 2 is used to dump the garbage to be processed into the pyrolysis incinerator 3. The pyrolysis incinerator 3 is provided with a smoke exhaust pipe 30. The smoke cooling and purification device is connected to the smoke exhaust pipe 30. The smoke cooling and purification device is used to cool and purify the smoke generated by the pyrolysis incinerator 3 and then discharge it into the atmosphere.

The smoke generated by the incineration will enter the smoke cooling and purification device through the smoke exhaust pipe 30; after the smoke is cooled and purified by the smoke cooling and purification device, the smoke that meets the environmental protection standards will be discharged into the atmosphere. The solid waste pyrolysis and incineration device cools and purifies the flue gas, so that the discharged flue gas meets environmental protection requirements and reduces secondary pollution. Moreover, the temperature of the treated flue gas is not high, which can avoid the risk of fire caused by high-temperature flue gas emissions.

[0024] like Figure 2 As shown, the flue gas cooling and purification device includes a spray cooling component 4, a water purification component 5 and an electrostatic purification component 6 which are connected in sequence. The water purification component 5 is provided with a spray component 7, and the output end of the spray component 7 is connected to the spray cooling component 4.

[0027] During operation, the flue gas generated by the cracking incinerator 3 flows into the spiral channel 44 through the smoke inlet pipe 41, and water mist is sprayed into the spiral channel 44 through the spray assembly 7. The water mist will mix with the flue gas and then flow in the spiral channel 44; the water mist and the flue gas can be mixed to cool the flue gas on the one hand, thereby achieving the purpose of cooling the flue gas; on the other hand, the water mist can also mix with the particulate matter in the flue gas and take away the particulate matter in the flue gas, thereby achieving the purpose of purifying the flue gas. When the gas-water mixture flows into the gas-water separation chamber 46, the water will continue to flow downward due to gravity, and then flow through the pipeline to the water purification assembly 5 for reuse; and the flue gas purified by the water mist will flow upward through the central channel 45, and then be discharged from the cooling tank through the smoke guide pipe 43 and flow into the water purification assembly 5 for water purification.

[0028] In this embodiment, water mist is sprayed out by the spray assembly 7 to mix with the flue gas, which can cool the flue gas on the one hand; on the other hand, particulate matter in the flue gas is removed by mixing the water mist with the flue gas to purify the flue gas.

[0030] In this embodiment, a cooling tower 8 is provided on one side of the spray cooling component 4, a drain pipe 48 is connected to the cooling tower 8, and an output end of the cooling tower 8 is connected to the water purification component 5.

By providing a plurality of tank bodies in the cooling tank, the residence time of the smoke in the spray system can be prolonged, thereby improving the purification and cooling effects. During specific operation, the smoke first passes through the spiral channel 44 of the smoke inlet tank 49, mixes with the water mist sprayed by the spray assembly 7, and undergoes the first cooling and purification; then the smoke flows out through the central channel 45 of the smoke inlet tank 49, and then enters through the spiral channel 44 of the transition tank 411, and mixes again with the water mist sprayed by the spray assembly 7, and undergoes the second cooling and purification; then the smoke flows out through the central channel 45 of the transition tank 411, and then enters through the spiral channel 44 of the smoke outlet tank 410, and mixes again with the water mist sprayed by the spray assembly 7, and undergoes the third cooling and purification, and finally flows out through the central channel 45 of the smoke outlet tank 410 to the smoke guide pipe 43, and is discharged from the spray system.

By providing four transition tanks 411, the residence time of the smoke in the spray system can be further increased, thereby improving the cooling and purification effects. In other embodiments, the number of transition tanks 411 can also be any other number.

[0033] An air-water mixing chamber 412 is provided on the mounting body 42 at a position corresponding to the spiral channel 44 of each cooling tank. By providing independent air-water mixing chambers 412, the water mist sprayed by the spray assembly 7 can be better contacted and mixed with the flue gas, while also preventing the flue gas from the rear cooling tank from flowing back into the front cooling tank, thereby ensuring that the flue gas can flow along a predetermined route and improving the stability of the operation.

[0034] like Figure 7-9 As shown, the water purification component 5 includes a clean water tank 51, an aeration water tank 52, a sewage purification tank 53 and an air-water separation tank 54.

The input end of the spray component 7 is connected to the clean water tank 51, and the output end of the spray component 7 is connected to the air-water mixing tube 55 and the air-water mixing chamber 412. The spray component 7 is used to spray clean water into the air-water mixing tube 55 and the air-water mixing chamber 412; the clean water in the clean water tank 51 is extracted by the spray component 7 and sprayed into the air-water mixing tube 55, so that the smoke and clean water are mixed in the air-water mixing tube 55.

[0035] The aeration assembly includes an aeration pump 56, the input end of the aeration pump 56 is connected to the air-water mixing tube 55, and the output end of the aeration pump 56 is connected to the aeration water tank 52; the aeration pump 56 is used to extract the air-water mixture in the air-water mixing tube 55 into the aeration water tank 52, and the aeration pump 56 extracts and transports it to the aeration water tank 52, so that the flue gas and water can fully contact, and the particulate matter in the flue gas is adsorbed by water molecules.

The sewage purification tank 53 is connected to the air-water separation tank 54. The air-water separation tank 54 is provided with a smoke outlet 57, which is connected to the electrostatic purification component 6. After the air-water mixture overflows into the sewage purification tank 53, purification liquid is added into the sewage purification tank 53 to separate the air and water in the sewage purification tank 53. Both the smoke and particulate matter will float to the water surface. After the smoke floats up, it will enter the air-water separation tank 54 and then be discharged into the electrostatic purification component 6 through the smoke outlet 57.

[0038] A filter press purification assembly 58 is provided on one side of the sewage purification tank 53. The input end of the filter press purification assembly 58 is connected to the sewage purification tank 53, and the output end of the filter press purification assembly 58 is connected to the clean water tank 51.

The output end of the return air pump 59 is connected to the air jet 510. The return air pump 59 is used to re-extract the flue gas in the sewage purification tank 53 into the aeration water tank 52. During the operation, after the flue gas and water in the sewage purification tank 53 are separated, the flue gas will float to the surface of the water; at this time, the flue gas is extracted by the return air pump 59, and the flue gas is re-injected into the aeration water tank 52 through the air jet 510 to mix with water, and the flue gas is purified again by water. By setting up the return air pump 59, the flue gas can be repeatedly mixed with water, and the particulate matter in the flue gas is eliminated as much as possible, thereby improving the purification effect of the waste incineration flue gas water purification and reuse system.

During the operation, the user will pour purification medicine into the sewage purification tank 53; after the gas-water mixture overflows into the sewage purification tank 53 through the aeration tank 52, the particles in the flue gas are separated from the flue gas, and the flue gas and the particles will float up, so that the water sinking to the bottom of the sewage purification tank 53 is all clean water. According to the principle of the communicating vessel, when the water level in the sewage purification tank 53 is higher than the end of the connecting pipe 513 extending into the clean water tank 51, the water in the sewage purification tank 53 will automatically flow into the clean water tank 51, and the lower layer of the sewage purification tank 53 is all clean water, and all the water flowing into the clean water tank 51 through the connecting pipe 513 is also clean water.

By adjusting the height of the end of the connecting pipe 513 extending into the clean water tank 51 by the water level regulating valve 514, the water level in the sewage purification tank 53 can be adjusted to ensure that the water flowing into the clean water tank 53 from the sewage purification tank 53 is all clean.

[0045] In order to facilitate the removal of particulate matter in the sewage purification tank 53, a scraper assembly and a slag collection tank 515 are provided in the sewage purification tank 53. The scraper assembly is used to collect the residue in the sewage purification tank 53 to the slag collection tank 515, and the input end of the filter press purification assembly 58 is connected to the slag collection tank 515. During operation, particulate matter will float to the water surface of the sewage purification tank 53, and the scraper assembly will collect the residue and sewage on the water surface of the sewage purification tank 53 to the slag collection tank 515, and then the filter press purification assembly 58 will extract the residue and sewage in the slag collection tank 515; then the filter press purification assembly 58 will collect the residue, and the filter press purification assembly 58 will also purify the sewage, and the purified water will be transported back to the clean water tank 51 for reuse.

[0046] Specifically, the scraper assembly includes a scraper motor 516, a scraper drive shaft 517 and a scraper transmission shaft 518 are arranged in the sewage purification tank 53, the output end of the scraper motor 516 is connected to the scraper drive shaft 517, the scraper drive shaft 517 and the scraper transmission shaft 518 are sleeved with a scraper transmission chain 519, and the scraper transmission chain 519 is provided with a scraper plate 520. When working, the scraper motor 516 works to drive the scraper drive shaft 517 to rotate, the scraper drive shaft 517 pulls the scraper transmission chain 519 and the scraper transmission shaft 518 to rotate, and the scraper transmission chain 519 drives the scraper plate 520 to move, and the scraper plate 520 scrapes the residue and sewage on the water surface of the sewage purification tank 53 into the residue collection tank 515; and then the residue and sewage are pumped away by the filter press purification assembly 58.

[0047] like Fig.10 , 11 As shown in the figure, the electrostatic purification assembly 6 includes a purification device body 62, which is a hollow structure. A gas-water separation device 63 is arranged on one side of the purification device body 62, and the gas-water separation device 63 is connected to the inner cavity of the purification device body 62. A smoke receiving pipe 64 is arranged on the side wall of the gas-water separation device 63, and the smoke receiving pipe 64 is connected to the smoke outlet 57. The gas-water separation device 63 is used to filter out moisture in the flue gas; an exhaust port 61 is arranged at the upper end of the purification device body 62, and the exhaust port 61 is connected to the external air. The flue gas after purification is discharged through the exhaust port 61. An ash discharge port 65 is arranged at the lower end of the purification device body 62, and the ash discharge port 65 is used to discharge the lumps generated during the purification process. An electrostatic dust removal device 66 is arranged in the purification device body 62, and the electrostatic dust removal device 66 is sealed and connected to the inner side wall of the purification device body 62. The electrostatic dust removal device 66 is used to absorb particulate matter in the flue gas.

[0048] During specific operations, the flue gas after water purification flows into the gas-water separation device 63 through the smoke receiving pipe 64, and then the water in the flue gas is removed by the gas-water separation device 63; then the flue gas with water removed will flow into the purification device body 62, and then flow into the electrostatic precipitator 66, and the electrostatic precipitator 66 can adsorb the particulate matter in the flue gas, and then the purified flue gas will be discharged into the atmosphere through the exhaust port 61; the particulate matter adsorbed in the electrostatic precipitator 66 will automatically fall to the ash discharge port 65 after agglomeration, and then be uniformly treated.

[0049] In this embodiment, the particulate matter in the flue gas is removed by the electrostatic precipitator 66 to achieve the purpose of purifying the flue gas so that it can meet environmentally friendly emission requirements, improve the environmental performance of the garbage pyrolysis incineration system, and reduce the harm of the flue gas generated by garbage incineration to the environment or human body.

[0050] The electrostatic precipitator 66 comprises an upper sealing plate 661 and a lower sealing plate 662, which are respectively sealed and connected to the inner side wall of the purification device body 62. A conical air collecting cavity 67 is provided above the upper sealing plate 661, and the exhaust port 61 is provided above the air collecting cavity 67. The lower part of the lower sealing plate 662 is connected to the gas-water separation device 63. After the smoke gas after the water is removed by the gas-water separation device 63 enters the purification device body 62, it first enters the lower sealing plate 662, and then flows into the electrostatic precipitator 66 for purification. The smoke gas purified by the electrostatic precipitator 66 will all flow into the air collecting cavity 67, and then be discharged into the air through the exhaust port 61.

[0051] A plurality of anode metal tubes 663 are arranged in an array on the upper sealing plate 661, and the other ends of the anode metal tubes 663 are respectively connected to the lower sealing plates 662, and the anode metal tubes 663 pass through the upper sealing plate 661 and the lower sealing plate 662 respectively, and a cathode metal wire 664 is respectively arranged in each anode metal tube 663, and the anode metal tube 663 and the cathode metal wire 664 are respectively connected to the controller 1. During operation, the anode metal tube 663 and the cathode metal wire 664 are powered by the controller 1, so that a high-voltage electric field is formed between the anode metal tube 663 and the cathode metal wire 664, so that the air in the anode metal tube 663 is ionized to generate positive and negative ions; when the flue gas passes through the anode metal tube 663, the dust particles therein collide with the gas ions, so that the dust particles are charged, and the dust particles move toward the anode metal tube 663 or the cathode metal wire 664, and will automatically deposit on the inner wall of the anode metal tube 663 or the cathode metal wire 664, and finally form blocks that fall down and will be discharged from the ash discharge port 65; after the dust particles in the flue gas are removed, the gas that meets the emission requirements flows into the exhaust port 61 through the gas collecting hole 67 and is discharged into the atmosphere.

[0052] In this embodiment, the cathode metal wire 664 is gap-matched with the inner wall of the anode metal tube 663, so that the flue gas can smoothly pass through the anode metal tube 663, so that the particles on the flue gas can adhere to the inner wall of the anode metal tube 663 or the cathode metal wire 664. In order to improve the stability of the structure, a counterweight block 665 is provided at the lower end of each cathode metal wire 664. By providing the counterweight block 665, the cathode metal wire 664 can be straightened, so that the gap between it and the anode metal tube 663 is always maintained.

[0053] The gas-water separation device 63 includes a gas-water separation housing 631, which is fixedly connected to the purification device body 62, and the smoke inlet pipe 41 is installed on the side wall of the gas-water separation housing 631 and communicates with the inner cavity of the gas-water separation housing 631. A water filter plate 632 is installed in the gas-water separation housing 631, and the water filter plate 632 is sealed and connected to the inner side wall of the gas-water separation housing 631; when the smoke enters the gas-water separation housing 631 through the smoke inlet pipe 41, the smoke will flow through the water filter plate 632, thereby filtering out the moisture in the smoke through the water filter plate 632, and the smoke with the moisture filtered will flow into the purification device body 62 through the gas-water separation housing 631.

[0054] In order to conveniently collect the water filtered by the water filter plate 632, a conical water collection tank 633 is provided at the lower end of the inner wall of the air-water separation housing 631, and a drain port 634 is provided at the lower end of the conical water collection tank 633. During operation, the water filtered by the water filter plate 632 will fall into the conical water collection tank 633, and then under the action of gravity, the water will automatically flow into the drain port 634 and be discharged from the air-water separation housing 631 through the drain port 634.

[0055] In order to facilitate the condensation of the particles falling from the cathode metal wire 664, a conical collecting hopper 68 is provided at the lower end of the purification device body 62, and an ash discharge port 65 is provided at the lower end of the conical collecting hopper 68. When the particles accumulated on the inner wall of the anode metal tube 663 or the cathode metal wire 664 form lumps, the lumps will fall into the conical collecting hopper 68 through the inner cavity of the anode metal tube 663 under the action of gravity, and finally fall out of the purification device body 62 through the ash discharge port 65 so as to be uniformly processed.

[0056] like Fig.12 , Fig.13As shown, the pyrolysis incinerator 3 includes a furnace body 31, and a plurality of support frames 32 are provided at the lower end of the furnace body 31. The plurality of support frames 32 facilitate the fixed installation of the garbage pyrolysis incinerator 3 to a preset installation position, for example, it can be fixedly installed on the ground or a table. A hopper assembly 33 is provided at the upper end of the furnace body 31, and the hopper assembly 33 is used to dump garbage into the furnace body 31. The hopper assembly 33 facilitates the dumping of garbage to be incinerated into the furnace body 31. A heat insulation layer 34 is provided on the inner wall of the furnace body 31. The heat insulation layer 34 is made of high temperature resistant material. The heat insulation layer 34 can reduce the heat dissipation through the furnace wall and maintain the high temperature environment inside the incinerator. At the same time, by providing the heat insulation layer 34, the external metal structure of the furnace body 31 can also be protected from the direct effect of high temperature, thereby preventing the metal furnace body 31 from being deformed or damaged due to high temperature, and providing a safe working environment for the staff.

[0057] A drying and gasification chamber 311, a cracking and gasification chamber 312, a carbonization and cracking chamber 313 and a combustion chamber 314 are sequentially arranged in the furnace body 31 from top to bottom. The side of the drying and gasification chamber 311 away from the cracking and gasification chamber 312 is connected to the hopper assembly 33. The smoke exhaust pipe 30 is fixedly mounted on the furnace body 31 and is connected to the drying and gasification chamber 311 in the furnace body 31. An ash collecting mechanism 35 is arranged in the furnace body 31. The ash collecting mechanism 35 is connected to the lower end of the combustion chamber 314 and is used to discharge the ash generated by the incineration of garbage. The furnace body 31 is provided with an oxygen supply device 36, a combustible gas injection mechanism 37 and a flue gas circulation mechanism 38. The oxygen supply device 36 is used to inject oxygen-enriched air into the combustion chamber 314. The combustible gas injection mechanism 37 is used to inject the combustible gas in the drying gasification chamber 311 into the combustion chamber 314. The flue gas circulation mechanism 38 is used to prolong the residence time of the flue gas in the cracking gasification chamber 312, thereby reducing the solid residue in the flue gas.

[0058] It should be noted that the drying gasification chamber 311 and the cracking gasification chamber 312 are both connected from top to bottom and closed on all sides; and the cracking gasification chamber 312 is a cone-shaped structure that is small at the top and large at the bottom. The carbonization cracking chamber 313 and the combustion chamber 314 are both connected from top to bottom and have side walls composed of porous plates, so that the oxygen supply device 36 can transport oxygen into the carbonization cracking chamber 313 and the combustion chamber 314.

[0059] 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 and gasification chamber 311 can also reach hundreds of degrees Celsius, but it is closed and oxygen-free here. The moisture in the garbage coming in from the hopper assembly 33 will evaporate rapidly at this temperature and crack into gas together with some substances in the garbage. Solid garbage continues to fall into the pyrolysis and gasification chamber 312, which is still closed and oxygen-free, and the garbage cannot be burned normally. The garbage continues to fall into the carbonization and cracking chamber 313 and the combustion chamber 314. The side walls of the carbonization and cracking chamber 313 and the combustion chamber 314 are opened with holes, and the temperature is high. Oxygen is supplied by the oxygen supply device 36, so that the carbonization and cracking chamber 313 and the combustion chamber 314 are fully supplied with oxygen, and the garbage can be fully burned; finally, it turns into gray ash and falls to the ash collecting mechanism 35, and is uniformly collected and processed by the ash collecting mechanism 35.

[0060] During the garbage incineration process, the combustible gas injection mechanism 37 can extract the combustible gas generated during the garbage cracking process from the drying gasification chamber 311 into the combustion chamber 314 for combustion, which plays a combustion-supporting effect, so that the garbage can be fully burned in the combustion chamber 314; in addition, the flue gas circulation mechanism 38 can increase the residence time of the flue gas in the furnace body 31, so that the residue in the flue gas can be burned more fully. By returning the flue gas to the furnace and injecting the combustible gas for combustion, the combustible residue and combustible gas in the flue gas can be reduced, thereby reducing the secondary pollution of the environment by the exhaust flue gas; it can also avoid the problem of combustible gas contacting the air and igniting again to cause a fire, thereby improving the safety of the operation. The flue gas generated after the garbage incineration will be discharged through the exhaust pipe 30 into the flue gas cooling and purification device for cooling and purification, and then discharged into the atmosphere.

[0061] In order to facilitate oxygen supply, in this embodiment, oxygen supply pipes 362 are respectively provided at positions corresponding to the combustion chamber 314 on the four side walls of the furnace body 31. The oxygen supply device 36 includes a plasma oxygen supply machine 361 fixedly mounted on the outer side wall of the furnace body 31, and the output end of the plasma oxygen supply machine 361 is connected to the oxygen supply pipe 362. The plasma oxygen supply machine 361 can extract air and increase the oxygen content in the air, and then transport the oxygen-enriched air to the oxygen supply pipe 362, and then flow into the combustion chamber 314 through the oxygen supply pipe 362, so that the combustion chamber 314 forms an oxygen-enriched environment, which can improve the garbage combustion efficiency and enable the garbage to be fully burned in the combustion chamber 314.

[0062] As mentioned above, when the garbage falls into the drying and gasification chamber 311, 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, a combustible gas injection mechanism 37 is provided on the furnace body 31.

[0063] Specifically, the combustible gas injection mechanism 37 includes a first exhaust fan 371, which is fixedly mounted on the outer wall of the furnace body 31. The input end of the first exhaust fan 371 is connected to the drying gasification chamber 311. Injection gas pipes 372 are respectively provided at positions corresponding to the combustion chamber 314 on the inner walls around the furnace body 31. The output end of the first exhaust fan 371 is connected to the injection gas pipe 372. The first exhaust fan 371 can extract the combustible gas in the drying gasification chamber 311 into the combustion chamber 314. During the operation, after the garbage is dumped into the drying gasification chamber 311, some combustibles in the garbage will be gasified into combustible gas due to the high temperature; the first exhaust fan 371 will extract these combustible gases, and then transport them to the induced gas pipe 372 through the pipeline, and then spray them into the combustion chamber 314 through the induced gas pipe 372; by adding combustible gas in the combustion chamber 314, the combustion temperature of the combustion chamber 314 can be increased, so that the garbage can be fully burned in the combustion chamber 314 and solid residue can be reduced.

[0064] In order to further improve the incineration effect, a heat reflection cover 39 is installed in the furnace body 31. The heat reflection cover 39 is arranged between the drying gasification chamber 311 and the cracking gasification chamber 312. The heat reflection cover 39 is provided with a plurality of small holes for the flue gas to pass through. The heat reflection cover 39 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 39 and then is discharged from the furnace body 31 through the exhaust pipe 30. The heavy smoke is blocked and falls into the furnace to continue burning, thereby increasing the residence time of the heavy smoke 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 is irradiated upward on the heat reflection cover 39, the heat reflection cover 39 will reflect it downward and radiate it, reducing heat loss and increasing the temperature in the furnace.

[0065] The flue gas circulation mechanism 38 includes a second exhaust fan 381, which is fixedly mounted on the outer side wall of the furnace body 31. A circulating suction pipe 382 and a circulating smoke outlet pipe 383 are respectively arranged at positions corresponding to the cracking and gasification chamber 312 on the inner side walls of the furnace body 31. The circulating suction pipe 382 is located above the circulating smoke outlet pipe 383. The circulating suction pipe 382 is connected to the input end of the second exhaust fan 381, and the circulating smoke outlet pipe 383 is connected to the output end of the second exhaust fan 381. By controlling the operation of the second exhaust fan 381, the flue gas in the upper part of the cracking and gasification chamber 312 can be drawn to the lower part of the cracking and gasification chamber 312, and then sent back into the furnace body 31 through the circulating smoke outlet pipe 383, thereby extending the residence time of the flue gas in the furnace body 31; thus, the harmful substances in the flue gas can be more fully decomposed by the high temperature in the furnace.

[0066] like Fig.13 , Fig.14As shown, the hopper assembly 33 includes a hopper body 331 with a hollow structure, the hopper body 331 is fixedly connected to the furnace body 31, one end of the hopper body 331 is connected to the drying and gasification chamber 311, and the other end is provided with an upper cover 332, which is used to cover the open end of the hopper body 331. One end of the upper cover 332 is hinged to the hopper body 331, and an opening and closing mechanism is provided on the hopper body 331, the output end of the opening and closing mechanism is connected to the upper cover 332, and the opening and closing mechanism is used to drive the upper cover 332 to flip along the hinged end, so as to drive the upper cover 332 to open or close through the opening and closing mechanism.

[0067] A sealing plate 333 is provided in the hopper body 331, one end of the sealing plate 333 is hinged to the inner side wall of the hopper body 331, and the sealing plate 333 can be sealed against the inner side wall of the hopper body 331; by setting the sealing plate 333 to be sealed against the hopper body 331, the sealing performance of the hopper body 331 can be improved, and smoke can be prevented from escaping from the hopper body 331 during operation, thereby ensuring the safety of processing and reducing secondary pollution. An opening mechanism is provided on the hopper body 331, and the output end of the opening mechanism is connected to the sealing plate 333. The opening mechanism is used to drive the sealing plate 333 to rotate and swing along the hinged end, thereby opening or blocking the inner cavity of the hopper body 331.

[0068] Before dumping the garbage, the upper cover 332 is driven to open by the opening and closing mechanism, and the sealing plate 333 is driven by the cover opening mechanism to open the inner cavity of the hopper body 331; then the garbage is dumped into the hopper body 331; after the garbage is dumped, the cover opening mechanism is controlled to drive the sealing plate 333 to flip downward, so that the sealing plate 333 blocks the inner cavity of the hopper body 331; then the upper cover 332 is driven to flip downward by the opening and closing mechanism, so that the upper cover 332 and the hopper body 331 are covered.

[0069] Specifically, the cover opening mechanism includes a pulling component and a pushing component, the pulling component and the pushing component are respectively connected to the hopper body 331, and the output ends of the pulling component and the pushing component are respectively connected to the sealing plate 333, the pulling component is used to pull the sealing plate 333 to flip upward along the hinged end, and the pushing component is used to push the sealing plate 333 to flip downward along the hinged end. When it is necessary to dump garbage, the sealing plate 333 is driven to flip upward along the hinged end by the pulling component, thereby opening the inner cavity of the hopper body 331, so that the garbage can be dumped into the furnace body 31 through the hopper body 331; after the garbage is dumped, the sealing plate 333 is pushed to flip downward along the hinged end by the pushing component, so that the sealing plate 333 can block the inner cavity of the hopper body 331.

The pulling motor 334 is fixedly installed on the hopper body 331, and the output end of the pulling motor 334 is connected to the driving wheel 336. When it is necessary to dump garbage, the pulling motor 334 is controlled to work, and the driving wheel 336 is driven to rotate on the mounting frame 335, and the driving wheel 336 will pull the steel cable 337 to be rolled up on the driving wheel 336, and then the sealing plate 333 is pulled upward along the hinged end by the steel cable 337, so as to open the inner cavity of the hopper body 331.

[0071] The pushing assembly includes a pushing cylinder 338, which is fixedly mounted on the outer wall of the hopper body 331. The output end of the pushing cylinder 338 can extend into the inner cavity of the hopper body 331, and the output end of the pushing cylinder 338 can abut against the upper end surface of the sealing plate 333. Under normal circumstances, the pushing cylinder 338 is in a retracted state; when the garbage is dumped, the sealing plate 333 is flipped open, and the pushing cylinder 338 works to make the output end of the pushing cylinder 338 extend until the output end of the pushing cylinder 338 abuts against the upper end surface of the sealing plate 333, and the sealing plate 333 is pushed to flip downward along the hinged end; when the opening angle of the sealing plate 333 is less than 90°, the sealing plate 333 will automatically flip downward under the action of gravity until it blocks the inner cavity of the hopper body 331. Then the pushing cylinder 338 is reset, so that the pushing cylinder 338 is retracted to the initial state.

[0072] In order to improve the sealing performance of the sealing plate 333 and the hopper body 331, sealing strips 339 are provided on the inner side walls around the hopper body 331 at positions corresponding to the sealing plate 333; when the sealing plate 333 is covered, the sealing plate 333 is sealed against the sealing strips 339. Through the cooperation between the sealing plate 333 and the sealing strips 339, the sealing plate 333 can be sealed against the hopper body 331, thereby improving the sealing performance of the sealing plate 333 and the hopper body 331, further preventing smoke from escaping, and improving the safety of the operation.

[0073] The opening and closing mechanism includes an opening and closing cylinder 3310, which is hinged to the hopper body 331, and the output end of the opening and closing cylinder 3310 is hinged to the upper cover 332. In the initial state, the upper cover 332 covers the hopper body 331, and the opening and closing cylinder 3310 is in a retracted state; when it is necessary to dump garbage, the opening and closing cylinder 3310 extends to drive the upper cover 332 to flip upward along the hinged end, thereby opening the upper cover 332 for dumping garbage; after the garbage is dumped, the opening and closing cylinder 3310 is controlled to retract, so that the upper cover 332 flips downward along the hinged end until the upper cover 332 covers the hopper body 331.

The output end of the ash discharge drive assembly 354 is connected to the spiral blade shaft 353 to drive the spiral blade shaft 353 to rotate. In the ash discharge process, by controlling the ash discharge drive assembly 354 to work, the spiral blade shaft 353 can be driven to rotate, and the spiral blades on the spiral blade shaft 353 can be used to break the white ash, and the white ash can also be pushed to the ash outlet 355, and finally fall from the ash outlet 355 for collection. The spiral blade shaft 353 breaks up the white ash and allows it to stay on the ash discharge pipe 352 for a while so that it can be completely extinguished, thereby reducing the possibility of the white ash discharged from the ash outlet 355 still being burned.

The feeding drive mechanism can drive the second transmission shaft 24 to rotate, thereby driving the feeding transmission assembly to move. The feeding barrel 22 is rotatably limited and connected to the feeding transmission assembly.

[0080] In the initial state, the loading bucket 22 is located at the lower end of the loading support frame 21; during operation, the garbage is dumped into the loading bucket 22; the loading drive mechanism then drives the second transmission shaft 24 to rotate, and the second transmission shaft 24 will drive the loading transmission assembly to move, and the loading bucket 22 is driven by the loading transmission assembly to move upward on the loading support frame 21; when the connection between the loading bucket 22 and the loading transmission assembly is higher than the first transmission shaft 23, the loading bucket 22 is also aligned with the upper end of the hopper body 331, and the loading bucket 22 will flip on the loading transmission assembly under the action of its own gravity, thereby dumping the garbage in the loading bucket 22 into the hopper body 331, and then falling into the furnace body 31, completing the automatic loading process for the pyrolysis incinerator 3. Afterwards, the loading drive mechanism drives the second transmission shaft 24 to rotate in the opposite direction, and the loading transmission assembly drives the loading bucket 22 to move downward to the initial position, so as to carry out the next round of loading process.

[0081] Through the cooperation of the feeding drive assembly, the first transmission shaft 23, the second transmission shaft 24 and the feeding transmission assembly, the feeding bucket 22 can be transported from a low place to a high place, thereby realizing the automatic feeding process for the pyrolysis incinerator 3, without the need for an additional counterweight crane or forklift, thereby reducing the operating cost of garbage incineration and improving efficiency.

[0082] In other embodiments, the feeding drive mechanism may also be connected to the first transmission shaft 23, or connected to the first transmission shaft 23 and the second transmission shaft 24 at the same time; it is only necessary to ensure that the feeding drive mechanism can drive the first transmission shaft 23 and / or the second transmission shaft 24 to rotate.

[0083] Specifically, the feeding transmission assembly includes a transmission gear 25 and a transmission chain 26. The transmission gear 25 is respectively sleeved on the first transmission shaft 23 and the second transmission shaft 24. The transmission chain 26 is sleeved on the transmission gear 25. The feeding bucket 22 is hinged to the transmission chain 26. During operation, the second transmission shaft 24 is driven to rotate by the feeding drive mechanism, thereby driving the transmission gear 25 to rotate. The rotation of the transmission gear 25 will drive the transmission chain 26 and the second transmission shaft 24 to rotate. The feeding bucket 22 is pulled up or down on the feeding support frame 21 by the transmission chain 26, so as to realize the processing process of feeding and resetting.

[0084] In this embodiment, there are two transmission chains 26, and two transmission gears 25 are respectively installed on the first transmission shaft 23 and the second transmission shaft 24. The two transmission chains 26 are symmetrically distributed along the center line of the loading support frame 21. By providing two transmission chains 26, the stability of the transmission can be improved, ensuring that the loading bucket 22 can stably rise and fall on the loading support frame 21.

[0085] A hinge 27 is welded on the side wall of the loading bucket 22, and a connecting rod 28 is welded on the other end of the hinge 27. The connecting rod 28 is fixedly connected to the transmission chain 26. A support block 29 is provided on the loading bucket 22, and the lower side wall of the connecting rod 28 can abut against the support block 29. In the initial state, the lower side wall of the connecting rod 28 abuts against the support block 29, so that the loading bucket 22 and the connecting rod 28 are limited and fixed to prevent the loading bucket 22 from rotating along the hinge 27; during the operation, when the loading drive mechanism drives the connecting rod 28 to cross the first transmission shaft 23, the loading bucket 22 will flip upward under its own gravity, so that the loading bucket 22 rotates along the hinge 27, thereby dumping the garbage into the pyrolysis incinerator 3; after the garbage is dumped, the loading drive mechanism drives the loading bucket 22 to reset, and the loading bucket 22 flips downward under its own gravity until the connecting rod 28 abuts against the support block 29. Through the cooperation between the connecting rod 28 and the supporting block 29, the loading bucket 22 and the connecting rod 28 can be limited and fixed, so as to prevent the loading bucket 22 from tilting during the loading process and improve the stability of the structure.

[0086] In order to improve the transmission stability of the loading bucket 22, first guide wheels 210 are respectively provided at both ends of the connecting rod 28, and guide grooves 211 are provided on the inner wall of the loading support frame 21. The first guide wheel 210 extends out of the corresponding guide groove 211 and slides with the corresponding guide groove 211; when the loading drive mechanism is working, the drive transmission chain 26 moves, driving the connecting rod 28 and the loading bucket 22 to move. At this time, the first guide wheel 210 will slide in the guide groove 211. Through the cooperation of the first guide wheel 210 and the guide groove 211, the movement direction of the connecting rod 28 can be limited and guided, thereby guiding the movement direction of the loading bucket 22, thereby improving the stability and accuracy of the transmission.

[0087] In order to enable the loading bucket 22 to turn over smoothly, a second guide wheel 212 is provided on the loading bucket 22, and the second guide wheel 212 extends into the guide groove 211 and slides with the guide groove 211. When the loading drive mechanism is working, the second guide wheel 212 will also slide in the guide groove 211, and the first guide wheel 210 and the second guide wheel 212 will slide in the guide groove 211, so that after the connecting rod 28 moves to cross the first transmission shaft 23, it can push the loading bucket 22 to turn over along the hinge 27, and realize the function of turning over the loading bucket 22 to dump garbage into the pyrolysis incinerator 3, ensuring that the loading bucket 22 can dump garbage into the pyrolysis incinerator 3, and improving the stability of the transmission.

[0088] In this embodiment, two limit rods 213 are further provided on the loading bucket 22, and the limit rods 213 can be connected to the front end surface of the loading support frame 21; by setting the limit rods 213, the loading bucket 22 can be prevented from tilting when rising or falling, so that it can smoothly transport and dump the garbage into the pyrolysis incinerator 3, thereby improving the stability of the work.

[0089] The feeding drive mechanism includes a feeding motor 214 and a reducer 215, the reducer 215 is fixedly mounted on the feeding support frame 21, the feeding motor 214 is fixedly mounted on the reducer 215 by screws, the output end of the feeding motor 214 is connected to the input end of the reducer 215, and the output end of the reducer 215 is connected to the second transmission shaft 24. When working, by controlling the feeding motor 214 to work, the reducer 215 can be driven, thereby driving the second transmission shaft 24 to rotate, and the second transmission shaft 24 drives the transmission chain 26 to move, so as to achieve the purpose of driving the feeding barrel 22 to rise or fall.

[0090] The solid waste pyrolysis and incineration device can automatically load the garbage and dump it into the pyrolysis incinerator 3 through the feeding mechanism 2, without manual feeding, which can reduce the labor cost of the operation. The sealing plate 333 installed on the hopper body 331 can prevent the flue gas from overflowing from the hopper during the incineration of the garbage, thereby ensuring the safety of the operation. During the incineration of the garbage, the oxygen supply device 36 and the combustible gas injection mechanism 37 can improve the combustion efficiency of the garbage and improve the garbage treatment capacity. The residence time of the flue gas in the furnace body 31 is extended by the flue gas circulation mechanism 38, so that it burns more fully, reduces the solid residue in the flue gas, reduces the flue gas emission of the garbage incineration, and improves the environmental protection performance. The flue gas generated during the garbage incineration process is cooled by the spray cooling component 4 and then sent to the water purification component 5 and the electrostatic purification component 6 in turn. The flue gas purified by the water purification component 5 and the electrostatic purification component 6 is then discharged into the air; after cooling and multi-layer purification, the discharged flue gas can meet the environmental protection standards, reduce the secondary pollution to the environment, and improve the environmental protection performance of the garbage incineration operation.
