Dandelion-like floccule adsorption equipment for printing and dyeing waste gas

Abstract

The invention discloses dandelion-like floccule adsorption equipment for printing and dyeing waste gas, belongs to the field of printing and dyeing waste gas treatment. The equipment aims to realize efficient interception of floccules in the waste gas through the arrangement of dandelion-like interception hemispheres on a bidirectional filter screen; therefore, the filter screen is effectively prevented from blocking; meanwhile, after floccules intercepted on the multi-branch flapper are saturated, the upper position and the lower position of the two-way filter screen are controlled to be reversed, so that air can be introduced between the dandelion type intercepting hemisphere and the selective permeable filter screen through the air inlet pipe; then, under the impact effect of air, due to the fact that the permeability becomes poor, the hairs gradually fall off and are separated from the dandelion type intercepting hemispheres, and the falling hairs are recycled and replaced throughthe sealing door; the dandelion type intercepting hemispheres can be replaced and cleaned under the condition that the waste gas treatment process does not need to be stopped, and the overall treatment efficiency of printing and dyeing waste gas is remarkably improved.

Description

technical field [0001] The invention relates to the field of printing and dyeing waste gas treatment, and more specifically relates to a dandelion-like floc adsorption device for printing and dyeing waste gas. 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 t...

Problems solved by technology

[0007] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a floc adsorption device imitating dandelion-style printing and dyeing waste gas, which can realize the flocculent adsorption equipment in the waste gas through the setting of the dandelion-style intercepting hemisphere on the two-way filter. High-efficiency interception of pollutants, so as to effectively protect the selective filter from being blocked. At the same time, when the flocs intercepted on the multi-branched lanceolus are saturated, the upper and lower positions of the two-way filter are controlled to be reversed. At this time, the dandelion-style Air is ventilated between the intercepting hemisphere and the selective permeable filter. At this time, under the impact of the gas, due to the poor permeability, the hair needles will gradually fall off and be separated from the dandelion-style intercepting hemisphere, and then the shedding hair needles will be removed through the airtight door. Recycling and replacement, realize the effect of replacing and cleaning the dandelion-style interception hemisphere without stopping the waste gas treatment process, and significantly improve the overall treatment efficiency of printing and dyeing waste gas
