A double-layer internal retreat type printing and dyeing waste gas treatment equipment

Abstract

The invention discloses a double-layer inward retreat type printing and dyeing waste gas treatment equipment, which belongs to the field of waste gas treatment. A double-layer inward retreat type printing and dyeing waste gas treatment equipment, through the arrangement of inward bead boards, under the action of waste gas, the inner retreat elastic layer is gradually compressed , so that more and more parts of the winding triangular edge are exposed to the inner retreating elastic layer, which in turn makes the ability to intercept the winding fluff fibers stronger, thereby effectively relieving the pressure of the arc-shaped filter screen to intercept impurities such as fluff fibers, so that it can be used for a long time Under the condition of use, it can still maintain a good ability to intercept fluff fibers, effectively avoiding the situation that the interception efficiency becomes worse and worse with the extension of use time. At the same time, the double-layer filter can be blown by wind and controlled The wind force fluctuates, which can make the floc fiber continuously rub against the winding triangular blade and be split, making it loose, significantly reducing the difficulty of cleaning and reducing the impact on the efficiency of printing and dyeing waste gas treatment.

Description

technical field [0001] The invention relates to the field of waste gas treatment, and more specifically relates to a double-layer inward retreat type printing and dyeing waste gas treatment equipment. Background technique [0002] Waste gas from the textile printing and dyeing industry mainly comes from two aspects: one is the spinning process of chemical fibers, and the other is the pre-treatment and functional finishing processes of textiles. [0003] Taking the spinning process of viscose fiber as an example, the raw materials need to be made into spinning liquid first, and a large amount of carbon disulfide needs to be added in the process of manufacturing spinning liquid, so the spinning process will release hydrogen sulfide, carbon disulfide, sulfur dioxide The main harmful gas substances. [0004] Heat setting machine treatment is an important part of the textile pretreatment process. During heat setting, various dye auxiliaries and coating auxiliaries on the textil...

AI Technical Summary

Problems solved by technology

[0005] Due to the particularity of textiles, the printing and dyeing exhaust gas contains a large amount of flocculent impurities, which are highly adhesive. Although they are easy to be filtered and intercepted, they are also easy to get stuck in the filter screen of the filter assembly due to their adhesiveness, resulting in The net is easily blocked and difficult to clean, which greatly affects the overall treatment efficiency of printing and dyeing waste gas
