Self-expanding umbrella skirt-shaped printing and dyeing waste gas treatment device

Abstract

The invention discloses a self-expanding umbrella skirt-shaped printing and dyeing waste gas treatment device, which belongs to the field of waste gas treatment, and is characterized in that when theself-expanding umbrella skirt-shaped printing and dyeing waste gas treatment device is used, a self-expanding interception column is controlled to rotate, the self-expanding interception column is outwards expanded and unfolded under the action of centrifugal force, and meanwhile, by matching the effect of a point pull rope, an umbrella skirt-shaped net surface structure can be formed between theself-expanding interception column and the expanded self-expanding interception column, so that most impurities such as batting in the waste gas can be intercepted when the waste gas is in contact with the filtering assembly; when batting cleaning is needed, the electromagnet is controlled to be powered off, the self-expanding interception column stops rotating, and through the effect of the batting discharging ring; the point pull rope can carry the interception batting to be separated from the self-expansion interception column, so that the difficulty of separating the batting from the self-expansion interception column is effectively reduced; meanwhile, the protection effect on the filtering assembly is effectively improved, the damage rate of the filtering assembly is effectively reduced, and the waste gas treatment cost input is reduced.

Description

technical field [0001] The invention relates to the field of waste gas treatment, and more specifically relates to a self-expanding umbrella skirt-shaped printing and dyeing waste gas treatment device. 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 texti...

Problems solved by technology

[0005] Due to the particularity of textiles, the printing and dyeing exhaust gas contains not only many impurities, but also hairy impurities such as fluff or fiber debris. The hairy impurities are strong in adhesion, and although they are easy to be filtered and intercepted, they are also easy to filter due to their adhesion. It is stuck in the filter screen of the filter assembly, causing the filter screen to be easily blocked, but due to the particularity of the fluff, it is very difficult to clean, especially when it is adhered to the porous and thin-walled structure of the filter screen, cleaning It is more difficult, not only will it affect the overall filtration efficiency, but it will also easily cause excessive damage to the filter components, resulting in an increase in the treatment cost of printing and dyeing exhaust gas
