Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fabric production, specifically to a waste gas treatment device for nispan fabric production. BACKGROUND

[0002] The source of fabric printing and dyeing waste gas mainly includes pre-treatment and post-treatment processes, as well as waste gas generated during the treatment of fabric by equipment such as setting machine, baking machine, singeing machine, and sanding machine. These waste gases contain organic gases such as formaldehyde, polystyrene, and aromatic hydrocarbons, as well as harmful substances such as fiber particles, dust, and smoke, which have a great impact on the environment and human health.

[0003] The present invention with publication number CN218853869U discloses a waste gas treatment device for nispan fabric production. The device rotates the adsorption plates to adsorb the waste gas and accelerate the flow speed of the waste gas inside the device, so that the waste gas can quickly reach the third box without accumulating and leaking inside the device, improving the working efficiency and the purification effect of the waste gas, and enhancing the practicality and safety of the device. However, the existing waste gas treatment device for nispan fabric production mostly relies on one air extractor to draw the waste gas into the device. Since the device is connected by pipelines, the power of the single air extractor is limited, and the waste gas cannot have enough conveying force to pass through the multiple filter plates inside the device, which may cause the waste gas to accumulate inside the device, affecting the working efficiency and possibly leading to waste gas leakage and pollution. Adding multiple air extractors will increase the cost and reduce the economy.

[0004] The existing waste gas treatment equipment transports the waste gas through the air pump during use. When the waste gas enters the treatment equipment, it needs to pass through the activated carbon adsorption filler. However, the conveying pressure of the waste gas is small, which cannot provide enough power for the waste gas to quickly pass through the activated carbon adsorption filler. In case of failure, the equipment needs to be stopped for maintenance, which will affect the treatment efficiency of the waste gas. To solve the above problems, the present application proposes a waste gas treatment device for nispan fabric production. SUMMARY
