Description

Technical Field

[0001] The utility model relates to the technical field of incineration, and in particular to a secondary combustion chamber structure for incinerating hazardous waste. Background Art

[0002] The secondary combustion chamber is the second combustion chamber connected. The incinerator is equipped with two combustion chambers, namely the primary combustion chamber and the secondary combustion chamber. It adopts a two-stage combustion method. The primary combustion chamber burns solids and the secondary combustion chamber burns gases. After the solid waste enters the primary combustion chamber, it is dried, anaerobic pyrolyzed, and burned out under predetermined temperature conditions, which effectively controls the generation of highly toxic gases. The gases produced by pyrolysis enter the secondary combustion chamber for full combustion, effectively treating toxic and harmful gases. In most of the existing technologies, after the waste is burned in the primary combustion chamber, the generated gases enter the secondary combustion chamber for combustion, and are directly discharged for recycling after the combustion is completed. Some gases may not be fully burned during the combustion process, and are discharged together with other gases through the exhaust valve, which causes some toxic gases to be discharged without being completely decomposed.

[0003] A search was conducted on the above-mentioned issues and it was found that in the currently disclosed prior art, there is a secondary combustion chamber structure for incinerating hazardous waste, such as that proposed in publication number CN214619597U. This structure has a mounting plate fixedly connected to the top of the interior of the chamber, the mounting plate is fixedly connected to the motor and the rotating shaft, a fan-shaped baffle is installed on the mounting plate, and the fan-shaped baffle is rotatably connected to the mounting plate. After the gas is burned once, the gas detector is used to detect whether the gas is qualified. If it is unqualified, the fan-shaped baffle is rotated to allow the gas to enter the chamber through the reflux duct next to the chamber for combustion again. If it is qualified, the gas is directly discharged for recovery. However, if the gas in this device is burned multiple times, some dust particles may be left inside the chamber, which may affect the subsequent combustion of the gas. Utility Model Content

The cylinder 2 is fixedly installed on the top of the chamber body 1 through the connecting block 3. The connecting block 3 is arranged inside the chamber body 1, and the connecting block 3 is fixedly connected to the output end of the cylinder 2. The connecting rod 4 is set to four, and the connecting rod 4 is fixedly installed on the side of the connecting block 3. The scraper 5 is set to four, and the scraper 5 is fixedly installed on the connecting rod 4. The reflux assembly is arranged on the side of the chamber body 1, and the recovery assembly is arranged inside the chamber body 1.

[0025] In this embodiment, the reflux assembly includes a reflux pipe 101, a ventilation box 102, an opening and closing plate 103, a connecting plate 104, a fixing plate 105, bolts 106 and a fan 107. The reflux pipe 101 is fixedly installed on the side of the chamber body 1 through the vent box 102, the opening and closing plate 103 is slidably installed inside the vent box 102, the connecting plate 104 is fixedly installed on the bottom of the opening and closing plate 103, and a threaded hole is opened on the connecting plate 104, the fixing plate 105 is fixedly installed on the side of the chamber body 1, and a plurality of threaded through holes are opened on the fixing plate 105, and the threaded through holes and the threaded holes are matched, the bolts 106 are arranged in the threaded holes of the connecting plate 104, and the fan 107 is fixedly installed on the inner wall of the chamber body 1.

[0026] In this embodiment, the recycling component includes a rotating shaft 201, an ash collecting plate 202, a motor 203 and an ash collecting box 204. The rotating shaft 201 is rotatably installed inside the chamber body 1, the ash collecting plate 202 is fixedly installed on the rotating shaft 201, the motor 203 is fixedly installed on the side of the chamber body 1, and the output end of the motor 203 is fixedly connected to the rotating shaft 201, and the ash collecting box 204 is slidably installed at the bottom end of the chamber body 1.

[0027] In this embodiment, the dust collecting plate 202 is fixedly mounted on the rotating shaft 201 in a curved shape. After the dust collecting plate 202 rotates, the dust can fall into the dust collecting box 204 at the bottom through the arc.
