[0019] S3: In the process of transporting the flue gas after the liquid medicine reaction through the gas guide pipe, the gas sucked by the suction end of the pump shell one is heated in the incineration cylinder through the spiral pipe, and the dry gas is input into the gas guide pipe together with the flue gas after the spraying reaction, so that the flue gas after the spraying is dried, avoiding that the too wet flue gas may increase the possibility of adhering to the filter screen, the driving wheel output end drives the driving wheel to rotate in the process of motor operation, the driving wheel with a radius greater than the driven wheel drives the pump shaft one to rotate through the driving belt linkage, the pump shaft one drives the impeller one to rotate, and the pump shaft two drives the impeller two to rotate in the pump shell two through the linkage of the synchronous wheel and the synchronous belt.

[0054] Example four:

[0055] Including base 1, burning cylinder 2, cylinder 4, spray tank 5, purification tank 6, pump shell 12, pump shell 13 and motor 16, the base 1 top is provided with the burning cylinder 2 which is inclined, the base 1 top is fixed with cylinder 4, spray tank 5 and purification tank 6, the burning cylinder 2 front is fixed with pump shell 12, pump shell 13, motor 16 and reduction box 19, the base 1 top is provided with symmetrical distribution ring seat 41, the burning cylinder 2 outer wall is sleeved with symmetrical distribution and rotationally installed in the ring seat 41 inside rotating ring 40, the motor 16 output end is connected with the reduction box 19 input shaft, the reduction box 19 output end is provided with gear 17, the burning cylinder 2 outer wall is sleeved with gear 17 meshing gear 18;

[0056] The base 1 top is provided with symmetrical distribution bearing seat 10, the bearing seat 10 inside rotationally installed with the rotation shaft 45 which is located at the center of the burning cylinder 2 and rotationally installed with the burning cylinder 2, the rotation shaft 45 outer wall is provided with multiple groups of ring array distribution of pushing plate 37;

[0057] The burning cylinder 2 inner wall is provided with equidistant distribution and located in the gap between the pushing plate 37 of the pushing block 38, the drive wheel 28 radius is greater than the driven wheel 30;

[0058] The inclined incineration cylinder 2 is the core, which is driven by the motor 16 to drive the gear 17-gear ring 18, so that the incineration cylinder 2 rotates around the ring seat 41 at a low speed of 0.5-3 rpm. The pushing block 38 installed on the inner wall of the incineration cylinder 2 is mechanically linked with the annular array of pushing plates 37 on the rotating shaft 45. When the incineration cylinder 2 rotates, the pushing block 38 periodically pushes the pushing plate 37, so that the hazardous waste is lifted and scattered in the cylinder, simulating "waterfall" flow. At the same time, the inclination angle of the incineration cylinder 2 is 5°-15°, combined with the action of gravity, which prolongs the residence time of the waste. The temperature is dynamically adjusted according to the type of waste. The temperature of waste containing chlorine is controlled at 800-850℃, and the temperature of waste containing alkaline earth metal is limited at 750-800℃. The power of the built-in thermocouple auxiliary gas / oil burner is adjusted in real time. The dynamic stirring mechanism increases the contact area between waste and oxygen, improves the decomposition rate of organic matter, reduces the residual loss rate, and controls the temperature according to the characteristics of different waste to avoid the generation of dioxin at high temperature and prevent the melting and corrosion of alkaline earth metal to the furnace lining. The inclined incineration cylinder 2 utilizes gravity to assist flow and does not require an additional stirring motor 16.

[0059] A hazardous waste high-temperature decomposition process, the steps of the hazardous waste high-temperature decomposition method are as follows:

[0060] S1: The hazardous waste is pre-stored through the feeding cylinder 4, and is transported to the inside of the rotating sleeve 48 through the feeding pipe 8, and is transported to the inside of the incineration cylinder 2 through the rotating sleeve 48. The incineration cylinder 2 rotates inside the ring seat 41 through the two groups of rotating rings 40 on the outer wall. The motor 16 operates to reduce the output shaft speed through the reduction box 19, so that the low-speed gear 17 pushes the gear ring 18 to rotate. The hazardous waste inside the incineration cylinder 2 is burned through the inclined surface of the incineration cylinder 2, so that the hazardous waste is fully burned during the flow process.

[0061] The harmful components in the waste are oxidized, decomposed and completely destroyed in a high-temperature environment. It is worth noting that, generally, increasing the incineration temperature helps to promote the decomposition and destruction of organic poisons in the waste, while inhibiting the generation of black smoke. However, too high an incineration temperature not only increases fuel consumption, but also increases the amount of metal volatilization in the waste, and even produces pollutants such as nitrogen oxide, thereby causing secondary pollution. Therefore, it is crucial to determine the appropriate incineration temperature. Through practice verification, the appropriate incineration temperature range of most organic matter is between 800 and 1100℃, and is usually controlled at about 800 to 900℃. For specific waste, such as waste containing chlorides, the temperature during incineration needs to reach 800 to 850℃ to ensure that chlorine gas can be converted into hydrogen chloride for recovery or removed by water washing. The temperature during incineration of waste containing alkaline earth metals should be controlled below 750 to 800℃ to prevent molten material from corroding and damaging the furnace lining and equipment.

7. A high-temperature decomposition process for hazardous waste, characterized in that: The hazardous waste high-temperature decomposition apparatus according to any one of claims 1-6 is used, and the steps of the hazardous waste high-temperature decomposition method are as follows: S1: Hazardous waste is pre-stored in the material cylinder (4) and transported to the inside of the rotating collar (48) through the feeding pipe (8). It enters the inside of the incineration cylinder (2) through the rotating collar (48). The incineration cylinder (2) rotates inside the ring seat (41) through two sets of rotating rings (40) on the outer wall. The motor (16) operates to reduce the output shaft speed through the reduction gearbox (19), so that the low-speed gear (17) drives the gear ring (18) to rotate. During the incineration of the hazardous waste inside the incineration cylinder (2), the waste flows through the inclined surface of the incineration cylinder (2), so that the hazardous waste is fully burned during the flow. Harmful components in waste are oxidized, decomposed, and eventually destroyed at high temperatures. It is worth noting that, generally speaking, increasing the incineration temperature helps to promote the decomposition and destruction of organic toxins in waste and suppress the generation of black smoke. However, excessively high incineration temperatures not only increase fuel consumption but also lead to an increase in the volatilization of metals in waste and even the generation of nitrogen oxide pollutants, thus causing secondary pollution. Therefore, determining the appropriate incineration temperature is crucial. Practical experience has shown that the suitable incineration temperature range for most organics is between 800 and 1100°C, usually controlled between 800 and 900°C. For specific wastes, such as those containing chlorides, the incineration temperature needs to reach 800 to 850°C to ensure that chlorine can be converted into hydrogen chloride for recovery or removed by water washing. When incinerating waste containing alkaline earth metals, the temperature should be controlled below 750 to 800°C to prevent corrosion damage to the furnace lining and equipment from the molten material. S2: The flue gas emitted from the incineration enters the spray pipe through the exhaust pipe (7), and part of the flue gas enters the feeding pipe (8). During the flow, it enters the exhaust pipe (7) through the arc structure of the return pipe (31) and the principle of heating and heat absorption. During the rotation of the incineration cylinder (2), it drives the push block (38) to rotate. During the rotation of the push block (38), it pushes the push plate (37). The push plate (37) rotates around the rotating shaft (45). When the hazardous waste conveyed inside the incinerator (2) passes through the pusher plate (37), it is lifted and scattered at a high position, which improves the flow of hazardous waste and helps to fully combust it. During the rotation of the rotating shaft (45), the conical teeth one (33) and the conical teeth two (34) mesh, driving the driven shaft (35) to rotate. When the driven shaft (35) rotates, it drives the scraper (36) to scrape the inner wall of the flue pipe (7) where it first contacts the flue gas. The dust in the flue gas will adhere to it. Over time, the inner wall of the exhaust pipe (7) will thicken, affecting the exhaust flow rate of the flue gas and hindering the full exhaust of the flue gas. The exhaust pipe (7) is scraped by the scraper (36) to avoid the accumulation of scale on the inner wall of the exhaust pipe (7) where the flue gas first comes into contact with the flue gas. After the flue gas enters the spray box (5), the suction force generated by the impeller (27) rotating inside the pump casing (13) is applied to the agent tank (3) through the liquid extraction pipe (23) and delivered to the nozzle (42) through the liquid delivery pipe (22) to spray the flue gas flowing upward in the spray box (5). The harmful substances in the flue gas react with the liquid. After the gas is sprayed, it is transported through the air guide pipe (9). The air guide pipe (9) transports the flue gas after the spray reaction into the purification box (6). The solid substances inside are filtered through the filter screen (44). When the filtered flue gas passes through the support net (46), it comes into contact with the activated carbon, adsorbs the harmful substances in the flue gas, and is output through the exhaust pipe (47). S3: During the process of transporting the flue gas after the reaction of the liquid medicine through the gas guide pipe (9), the gas drawn by the suction end of the pump casing (12) is heated inside the incinerator (2) through the spiral tube (39). The heated and dried gas is input into the gas guide pipe (9) and mixed with the flue gas after the spray reaction. The sprayed flue gas is dried to avoid the possibility of excessively humid flue gas adhering to the filter screen (44). During the operation of the motor (16), the output end of the drive wheel (28) drives the driven wheel (30) to rotate. Through the drive wheel (28) with a radius larger than the driven wheel (30), the drive belt (29) drives the pump shaft (25) to rotate. The pump shaft (25) drives the impeller (24) to rotate. When the pump shaft (25) rotates, the synchronous wheel (14) and the synchronous belt (15) drive the pump shaft (26) to rotate. The pump shaft (26) drives the impeller (27) to rotate inside the pump casing (13).
