[0039] Embodiment 4:

[0040] On the basis of the first embodiment, this embodiment describes one of the implementable structures of the cyclone assembly, the cyclone assembly includes a fixed bracket 16 fixedly arranged in the purification box 1, a cyclone plate 17 is rotatably arranged at the bottom of the fixed bracket 16, water tanks 18 are fixedly arranged on both sides of the purification box 1, a connecting pipe 19 is fixedly arranged on one side of the water tank 18, one side of the connecting pipe 19 penetrates the outer wall of the purification box 1 and is fixedly connected to the spray pipe 20, the spray pipe 20 is arranged in a concentric circle shape, and a plurality of nozzles 21 are fixedly arranged on the circumference of the bottom of the spray pipe 20;

[0041] In this embodiment, the fixed bracket 16 plays the role of fixing and supporting the swirl plate 17, which is arranged in a cross shape, and can reduce the influence on the movement of the exhaust gas. The swirl plate 17 can rotate. When the exhaust gas passes through the swirl plate 17, the exhaust gas will pass through the inside of the swirl plate 17, thereby driving the swirl plate 17 to rotate. The rotation of the swirl plate 17 changes the movement path of the exhaust gas, so that the exhaust gas is fully in contact with the catalyst sprayed from the nozzle 21, so that the exhaust gas purification effect is better and the efficiency is higher. The water tank 18 is arranged on both sides of the purification box 1. The catalyst that can purify the exhaust gas is stored in the water tank 18, and is transmitted to the spray pipe 20 through the connecting pipe 19. The spray pipe 20 is then transmitted to the nozzle 21, and finally the catalyst is sprayed out;

[0042] The spray pipe 20 is arranged in a concentric circle shape to increase the number of installed nozzles 21, and also makes the catalyst sprayed from the nozzles 21 cover a wider area, so that the exhaust gas and the catalyst are in closer contact, and the mixing and purification efficiency is higher.

[0043] The drive motor 13, swirl plate 17, nozzle 21 and filter plate 22 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art, and the specifications and models of the drive motor 13, swirl plate 17, nozzle 21 and filter plate 22 are well known to those skilled in the art and will not be described in detail here.

[0044] Working principle: When it is necessary to purify the dust-containing organic waste gas, first introduce an appropriate amount of water into the treatment box 4, then introduce the dust-containing organic waste gas into the treatment box 4 through the air inlet pipe 2, and then turn on the drive motor 13 and the nozzle 21. When the waste gas is at the bottom of the treatment box 4, the diverter plate 6 can change the trajectory of the waste gas at the bottom of the treatment box 4, so that the waste gas is fully in contact with the water. The partition plate 7 blocks the other paths of the waste gas, leaving only the through hole 9 for the waste gas to pass through. The through hole 9 is arranged opposite to the air inlet pipe 2, which can increase the movement path of the waste gas and increase the contact time between the waste gas and water, so as to achieve a better dust removal effect.

[0045] The driving motor 13 can drive the stirring rods 14 to rotate. The stirring rods 14 are arranged equidistantly around the circumference, and the number is four. The knocking rods 15 on the stirring rods 14 are also driven to rotate, thereby pressing down the stirring plate 10. Under the action of the spring 12, the stirring plate 10 will continuously vibrate up and down, so that the exhaust gas and water are mixed better and the dust removal effect is better;

[0046] When the exhaust gas passes through the swirl plate 17, the exhaust gas will pass through the inside of the swirl plate 17, thereby driving the swirl plate 17 to rotate. The rotation of the swirl plate 17 changes the movement path of the exhaust gas, so that the exhaust gas is fully in contact with the catalyst sprayed from the nozzle 21. The water tank 18 is arranged on both sides of the purification box 1. The catalyst that can purify the exhaust gas is stored in the water tank 18 and is transmitted to the spray pipe 20 through the connecting pipe 19. The spray pipe 20 is then transmitted to the nozzle 21, and finally the catalyst is sprayed out;

[0047] Finally, the purified gas passes through the filter plate 22 at the top and is discharged from the exhaust pipe 3.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
