The driven bevel gear 203 is rotatably connected to the inner surface of the bottom tank 11. A driving wheel 204 is fixedly connected to the driven bevel gear 203. A first synchronous belt 205 is connected to the driving wheel 204. The other end of the first synchronous belt 205 is connected to a driven wheel 206. When the motor 201 is started, the motor 201 drives the driving bevel gear. 202 rotates, the active bevel gear 202 rotates and drives the driven bevel gear 203 to rotate, the driven bevel gear 203 rotates and drives the active wheel 204 to rotate, and drives the driven wheel 206 to rotate through the first synchronous belt 205. The bottom tank 11 is equipped with a cleaning mechanism. The motor 201 is used to drive the cleaning mechanism to rotate. The bottom tank 11 is equipped with an ignition mechanism. The box 1 is equipped with a detection mechanism. The side of the box 1 near the motor 201 is equipped with an exhaust mechanism. The side of the bottom tank 11 near the center of the box 1 is equipped with an observation mechanism. The side of the box 1 near the bottom tank 11 is fixedly connected with an exhaust pipe 6. Several activated carbon plates 9 are snapped onto the inner surface of the box 1. Several support feet 10 are provided at the bottom of both the box 1 and the bottom tank 11.

[0018] The cleaning mechanism includes a rotating shaft 301, which is fixedly connected to the driven wheel 206. The rotating shaft 301 is rotatably connected to the inner surface of the bottom tank 11. A connecting plate 302 is fixedly connected to the bottom of the rotating shaft 301. Two scrapers 303 are fixedly connected to the bottom of the connecting plate 302. The scrapers 303 have a spiral structure and are slidably connected to the inner wall of the bottom tank 11. The rotation of the rotating shaft 301 drives the two scrapers 303 to rotate through the connecting plate 302, thereby scraping off the residue that adheres to the inner wall of the bottom tank 11 when the fireworks and firecrackers are burning. The scraped residue will fall down to the bottom of the bottom tank 11 for collection.

[0019] The ignition mechanism includes a tray 401, which is fixedly connected to the top of the bottom tank 11. The diameter of the tray 401 is smaller than the inner wall diameter of the bottom tank 11. The surface of the tray 401 is inclined.

Then, the movable door 801 is closed, and potassium permanganate solution or other colorimetric solution is poured into the test bottle 503.

[0024] After the ignition device 403 ignites the fireworks, it starts the motor 201. The motor 201 drives the active bevel gear 202 to rotate. The rotation of the active bevel gear 202 drives the driven bevel gear 203 to rotate. The rotation of the driven bevel gear 203 drives the active wheel 204 to rotate, and through the first synchronous belt 205, drives the driven wheel 206 and the rotating shaft 301 to rotate. The rotation of the rotating shaft 301 drives the two scrapers 303 to rotate through the connecting plate 302, which scrapes off the adhering material on the inner wall of the bottom tank 11 when the fireworks are burning. The scraped adhering material will fall down to the bottom of the bottom tank 11 for collection.

[0025] When the air pump 502 is activated, it pumps the smoke generated by the burning fireworks in the bottom tank 11 into the test bottle 503 in the box 1 through the air guide pipe 501. The sulfur dioxide in the smoke reacts with the potassium permanganate solution and changes the color of the potassium permanganate solution. When the pressure in the first test bottle 503 reaches a certain level, the smoke is transferred to the next test bottle 503 through the connecting pipe 504. By observing the state of the solution in several test bottles 503, the environmental performance of the burning smoke can be tested.

[0026] As the output of motor 201 rotates, it also drives the drive pulley 701 to rotate. The rotation of the drive pulley 701 drives the driven shaft 703 to rotate through the second synchronous belt 702. The rotation of the driven shaft 703 drives several fan blades 705 to rotate. The rotation of the several fan blades 705 can purify and filter the flue gas in the box 1 through several activated carbon plates 9 and then discharge it outside the box 1 to avoid causing environmental pollution.
