A floc adsorption equipment imitating dandelion printing and dyeing waste gas

Abstract

The invention discloses a dandelion-like floc adsorption device for printing and dyeing waste gas, which belongs to the field of printing and dyeing waste gas treatment. A floc adsorption device for imitating a dandelion-style printing and dyeing waste gas, through the setting of a dandelion-style intercepting hemisphere on a two-way filter, It can realize the efficient interception of flocs in the exhaust gas, so as to effectively protect the selective permeable filter from being blocked. At the same time, when the flocs intercepted on the multi-branch lanceolus are saturated, the upper and lower positions of the two-way filter are controlled to be reversed. At this time You can ventilate between the dandelion-style interception hemisphere and the selective permeability filter through the ventilation inlet pipe. At this time, under the impact of the gas, due to the poor permeability, the hair needles will gradually fall off and separate from the dandelion-style interception hemisphere, and then pass through The airtight door recycles and replaces the shedding hair needles, realizing the effect of replacing and cleaning the dandelion-style interception hemisphere without stopping the waste gas treatment process, and significantly improving the overall treatment efficiency of printing and dyeing waste gas.

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
