Description
Technical Field
[0001] The utility model mainly relates to the technical field of waste gas treatment, and specifically relates to VOCs waste gas treatment equipment. Background Art
[0002] VOCs are volatile organic compounds, a common type of air pollutant produced in chemical industries such as paint production, chemical fiber industry, metal coating and chemical coatings.
[0003] The existing patent (publication number: CN216778462U) discloses a VOCs waste gas treatment device, including a main body and an adsorption component for treating the waste gas, wherein the adsorption component includes air guide frames respectively arranged on both sides of the main body, two air inlet plates arranged on both sides of one of the air guide frames, an air guide plate arranged on one side of the main body, a plurality of air guide holes evenly arranged on one side of the air guide plate, a support frame arranged on the other side of the main body, a fan arranged on one side of the support frame, and an adsorption frame arranged on the other side of the support frame. The utility model can guide the waste gas by arranging a main body, an air guide plate, a fan, a spray plate and a filter plate. The fan increases the flow rate of the gas entering the main body, and the activated carbon in the adsorption chamber can adsorb and purify the waste gas, thereby improving the practicability of the equipment for treating the waste gas, and solving the problem that the existing equipment has a poor adsorption and purification effect on the VOCs waste gas, which easily causes the unpurified waste gas to be discharged into the air, pollutes the air, and reduces the practicability of the equipment for treating the VOCs waste gas.
[0004] In the process of implementing the solution, the inventor uses a fan to pump the VOCs waste gas within the body. The body of the VOCs waste gas treatment equipment in the prior art adopts a straight-through structure design.

[0051] The filter tube 5 has a built-in filter sheet 53 to filter the VOCs waste gas, wherein the exhaust fan 51 at the front end of the filter tube 5 pumps the VOCs waste gas at the rear end of the filter tube 5 to the front end thereof.
[0052] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a maintenance port is fixedly provided on the left side of the filter tube 5, and a hatch 6 is hinged on the left side of the maintenance port.
[0053] The design of the maintenance port and the hatch 6 facilitates the user to replace the filter sheet 53 on the left side of the filter tube 5, thereby improving the convenience of replacing the consumables of the equipment.
[0054] Specific operation process:
[0055] The front upward zone 3 and the rear downward curved zone 2 arranged in the spray pipe 1, combined with the front baffle 11 and the rear baffle 12, increase the conveying path length of the VOCs waste gas in the equipment.
