[0022] Please see Figure 1-2 This utility model provides a technical solution: a high-temperature pyrolysis furnace with a flue gas treatment device, including a pyrolysis furnace body 1 and a shell 2 disposed on one side of the pyrolysis furnace body 1. The top of the pyrolysis furnace body 1 is provided with a flue pipe 3, one end of which is connected to the shell 2. A partition 4 is provided inside the shell 2, dividing the interior of the shell 2 into a filter chamber and a spray chamber. A main shaft 5 is rotatably mounted inside the shell 2, one end of which penetrates the side wall of the shell 2 and is fixedly mounted with a turntable 6. A motor 7 is provided on the outer wall of the shell 2, and a drive gear 8 is installed on the drive end of the motor 7. The outer circumference of the turntable 6 is provided with a gear ring 9 that meshes with the drive gear 8. The partition plate 4 is provided with a ventilation port for the main shaft 5 to pass through. The top of the housing 2 is provided with an exhaust fan 10 that communicates with the spray chamber.

[0023] By adopting the above technical solution, the interior of the shell 2 is divided into a filter chamber and a spray chamber by the partition 4, so as to realize the staged treatment of flue gas and improve the treatment effect. The motor 7 drives the turntable 6 to rotate through the transmission of the drive gear 8 and the gear ring 9, and then drives the spray pipe 11 to rotate through the linkage component to achieve uniform spray distribution. At the same time, the main shaft 5 drives the baffle 26 to rotate, slowing down the air flow speed and improving the spray treatment effect. The filter component is designed to automatically clean the filter screen and reduce manual maintenance.

[0024] In this embodiment, the linkage component includes an eccentric shaft 15 disposed on the side wall of the turntable 6, a pair of longitudinally arranged guide grooves 16 are provided on the outer wall of the housing 2, a pair of guide rods 17 are slidably disposed in the pair of guide grooves 16, and a slide 18 that can slide up and down is provided between the pair of guide rods 17. The slide 18 is fitted onto the eccentric shaft 15 through an internal slide groove, and the eccentric shaft 15 can slide in the slide groove. A rack 19 is provided on the upper wall of the slide 18, and a transmission gear 20 that meshes with the rack 19 is sleeved on the outer wall of the spray pipe 11.

[0025] By adopting the above technical solution, the design of the eccentric shaft 15 and the slide 18 allows the spray pipe 11 to move up and down with the rotation of the turntable 6. Through the cooperation of the rack 19 and the transmission gear 20, the spray pipe 11 can swing back and forth, ensuring the uniform distribution of spray.

[0026] In this embodiment, the filter assembly includes a conical filter screen 21 disposed in the filter chamber. One end of the bottom circle of the conical filter screen 21 is fixedly connected to the side wall of the partition plate 4. One end of the main shaft 5 passes through the conical filter screen 21 and is fixedly mounted with a cleaning brush 22. The cleaning brush 22 is in contact with the outer wall surface of the conical filter screen 21.

[0027] By adopting the above technical solution, the design of the conical filter screen 21 can effectively filter particulate matter in flue gas and improve the filtration effect. The design of the cleaning brush 22 can automatically clean the conical filter screen 21 as the main shaft 5 rotates, reducing manual maintenance.

[0028] In this embodiment, the filter chamber is further provided with an ash discharge hopper 23 at the bottom, the spray chamber is provided with a liquid discharge chamber at the bottom, and the liquid discharge chamber is provided with a liquid discharge pipe 24 at the bottom.

[0031] By adopting the above technical solution, the design of the support frame 25 ensures the stable support of the shell 2.

[0032] In this embodiment, the housing 2 is further configured such that a mounting bracket for fixing the motor 7 is provided on the side wall.

[0033] By adopting the above technical solution, the design of the mounting base improves the reliability of motor 7 and ensures the stability of transmission.

[0034] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0035] Example: The pyrolysis furnace body 1 pyrolyzes waste to generate flue gas. The flue gas enters the filter chamber of the shell 2 through the exhaust pipe 3. The flue gas undergoes preliminary filtration through the conical filter screen 21 to remove large particles. The motor 7 is started, and the motor 7 drives the drive gear 8 to rotate. The gear ring 9 drives the turntable 6 and the main shaft 5 to rotate. The main shaft 5 drives the cleaning brush 22 to rotate. The cleaning brush 22 is in contact with the outer wall of the conical filter screen 21 to remove the dust accumulated on the filter screen. The flue gas enters the spray chamber through the ventilation port. The spray system is started. The liquid delivery pipe 13 can spray the spray liquid through the spray pipe 11 and the nozzle 14 through the pump body. It reacts chemically with the harmful substances in the flue gas to neutralize and purify them. At this time, the turntable 6 drives the eccentric shaft 15 to rotate. The eccentric shaft 15 simultaneously moves in the slide groove. The internal sliding mechanism drives the slide 18 to move up and down. The rack 19 above the slide 18 slides up and down accordingly and drives the spray pipe 11 to rotate back and forth through the transmission gear 20. The nozzle 14 below the spray pipe 11 swings back and forth to increase the spray area. At the same time, the main shaft 5 drives the baffle 26 to rotate, which slows down the flow speed of the flue gas and increases the reaction time of the spray purification, thereby improving the purification effect. The purified gas is discharged from the housing 2 through the exhaust fan 10. After the treatment is completed, the ash hopper 23 at the bottom of the filter chamber can collect the filtered dust. The ash hopper 23 should be cleaned regularly to ensure that it is unobstructed. The liquid drain chamber at the bottom of the spray chamber collects the sprayed liquid and discharges it through the liquid drain pipe 24. The unobstructedness of the liquid drain pipe 24 should be checked regularly to avoid blockage. It is easy to use.
