Double-layer inward-retreating type printing and dyeing waste gas treatment equipment

Abstract

The invention discloses double-layer inward-retreating type printing and dyeing waste gas treatment equipment, belonging to the field of waste gas treatment. According to the double-layer inward-retreating type printing and dyeing waste gas treatment equipment in the invention, an inward bead plate is arranged, an inward-retreating elastic layer is gradually compressed under the action of exhaustgas, so more and more parts of a winding triangular blade expose out of the inward-retreating elastic layer, the capability of intercepting and winding fluff fibers is stronger, and pressure in intercepting impurities such as batting fibers by an arc-shaped filter screen is effectively relieved; and thus, under the condition of long-time use, good fluff fiber intercepting capability can still be maintained, and the situation that the interception efficiency becomes worse and worse along with the prolonging of service time is effectively avoided. Meanwhile, wind power can be blown to a double-layer filter screen, and the wind power is controlled to be variable, so batting fibers can be continuously rubbed with the winding triangular blade and are thus cut apart and loosened, cleaning difficulty is remarkably reduced, and the influence on printing and dyeing waste gas treatment efficiency is reduced.

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
