Description

Technical Field

[0001] The utility model belongs to waste gas treatment equipment, and particularly relates to a multi-stage industrial waste gas treatment device. Background Art

[0002] Flammable organic waste gas is directly burned into carbon dioxide and water by thermal combustion method or catalytic combustion method.

[0003] After retrieval, in the prior art, there is an environmental protection equipment for waste gas treatment with a publication number of CN117869906A. The ignition of the spark plug generates heat to heat the residual waste gas. At the same time, the thrust generated during the combustion process drives the sliding of the push plate in the tank, enabling the push plate to contact the communication groove. Through the trapezoidal structure of the communication groove, the spatial communication in the up and down directions of the push plate can be realized. At this time, the burned waste gas is circulated to the lower part of the push plate. The process of igniting the waste gas in this device controls the spark plug to keep firing until the pressure can push the push plate to cooperate with the communication groove. Then, after the waste gas is transmitted for a while, it is reset through the spring, resulting in too much burned gas remaining in the tank and the push plate cavity, reducing the combustion components and affecting the next ignition. The combustion generates insufficient thrust and cannot indirectly ignite the internal gas according to the pressure. Instead, the gas is poured into the next process at high pressure all at once.

[0004] After retrieval, in the prior art, there is a chemical waste gas treatment equipment with a publication number of CN117122997B. By inserting the activated carbon filter plate into the filter box, the activated carbon filter plate can preliminarily filter the industrial waste gas entering the filter box through the air inlet pipe. The filter plate is manually replaced. Those skilled in the art know that the filter plate is a consumable part and needs to be frequently replaced, with one piece installed each time, increasing the labor intensity.

[0005] Based on the problems found in the prior art, a multi-stage industrial waste gas treatment device is proposed, which can adjust the ignition timing of the spark plug according to the appropriate pressure of the burned waste gas, and at the same time has an automatic filter plate replacement function, which can reduce the labor intensity.

[0043] The working principle of an industrial waste gas multi-stage treatment device:

[0044] In use, first, the waste gas enters the automatic plate-changing assembly 1 through the main pipeline 15. The gas is filtered by the filter plate 13. After the filter plate 13 works for a long time, the filtering effect will be greatly reduced. Therefore, the filter plate 13 needs to be replaced. A plurality of spare filter plates 13 are placed in the placement bin. When the filter plate 13 needs to be replaced, the driving motor on the lead screw assembly II 14 drives the lead screw to rotate, driving the filter plate 13 to move towards the sliding groove side at the end of the main pipeline, so that the horizontal plate at the upper end of the filter plate 13 comes into threaded engagement with the lead screw assembly I 11. The driving motor on the lead screw assembly I 11 drives the lead screw to rotate, and the lead screw on the lead screw assembly I 11 drives the filter plate 13 to move towards the sliding groove and cooperate with the main pipeline 15 for filtering. The filtered filter plate 13 is moved to the plate-taking bin on the other side by the rotation of the lead screw on the lead screw assembly I 11. The spring plate 16 pushes the filter plate 13 to prevent the filter plate 13 from staying at one end of the plate-taking bin, so that when the lead screw assembly I 11 drives the filter plate 13 to move towards the plate-taking bin next time, the two filter plates 13 will be stuck;

[0045] After the waste gas is filtered by the automatic plate-changing assembly 1, it enters the spark plug combustion assembly 2. The gas pushes open the one-way valve 27 and enters the housing II 21. By increasing the gas volume, the pressure detection assembly 26 is pushed. When it reaches a certain value, the spark plug 28 starts to ignite the internal waste gas and burn the unburned gases such as carbon monoxide inside. Driven by the thrust generated by the combustion, the support plate 24 slides towards the water bath spraying assembly 3 side. Through the trapezoidal groove on the cylinder, the gas enters the water bath spraying assembly 3. The driving motor is started to drive the mixing plate 311 to rotate. When the mixing plate 311 rotates, it drives the bevel gear 316 to rotate around the bevel gear disk 314. The bevel gear disk 314 meshes and rotates with the bevel gear disk 314, driving the spoiler fan 312 to rotate. The spoiler fan 312 drives the short connecting plate 313 to rotate. The short connecting plate 313 realizes the linkage of multiple spoiler fans 312 through the long connecting plate. The spoiler fan 312 assists the mixing plate 311 to mix and stir the gas. The treated waste gas liquid is sprayed on the mixing plate 311 through the water bath rack 33. The mixing plate 311 stirs the waste gas and the waste gas treatment liquid for water bath treatment. After the treatment, it is subjected to a secondary water bath treatment. Through the atomization assembly 4, gas and waste gas treatment liquid are injected into the air inlet pipe 432 and the liquid inlet pipe 44 by an external device. The waste gas treatment liquid is ejected from the end of the treatment liquid pipe 433, and the air inlet pipe 432 discharges gas. The liquid passes through the narrow nozzle at high speed. According to the Venturi effect, a negative pressure is generated around the nozzle to carry the liquid medicine into the high-speed air flow and crush it into mist droplets of different sizes for atomization effect, so that the waste gas treatment liquid is fully combined with the waste gas and the reaction effect with the waste gas is increased;

[0046] Finally, the gas passes through the filter cylinder 5. Filtering substances can be added to the net plate in the filter cylinder according to requirements to filter the gas again.
