Background

The waste gas of textile printing and dyeing industry mainly comes from two aspects, namely, the spinning process of chemical fiber, and the textile pretreatment and functional after-finishing processes. Taking the spinning process of viscose fiber chemical fiber as an example, raw materials need to be made into spinning solution, and a large amount of carbon disulfide needs to be added in the process of making the spinning solution, so harmful gas substances mainly comprising hydrogen sulfide, carbon disulfide and sulfur dioxide are released in the spinning processing process. The heat setting machine treatment is an important part of the textile pretreatment process. During heat setting, various dye assistants and coating assistants on the textile are released, so that a large amount of VOCs (volatile organic compounds) are released at the opening of the exhaust pipeline finally. The organic gases are mainly formaldehyde, polyphenyl, aromatic hydrocarbons and other organic gases. In the functional after-finishing process of the textile, waste gas mainly comes from two links. In the hot-melting dyeing process of the polyester disperse dye, a certain micromolecular dye is sublimated into waste gas and is discharged due to high temperature. The non-ironing and flame-retardant finishing of the cotton fabric is carried out through a baking link, and due to the addition of some chemical additives, the phenomenon that aldehyde gases such as formaldehyde and the like and ammonia gas are released during baking can occur.

Textile printing and dyeing waste gas generally filters back dust and large granule pollutant earlier through preprocessing equipment (dust granule gets rid of the filtration, atomizing spouts the lin tower, water vapor separator, equipment such as high temperature cooling), through plasma UV photodissociation deodorization exhaust gas purifier high row again, but often the filter effect is relatively poor when through preprocessing equipment, efficiency is lower, be difficult to realize high-efficient high-quality continuation filtration, it is great to lead to subsequent clarifier pressure, and often remaining dust or granular pollutant damage the clarifier easily, even still have a small amount of dust and granular pollutant in the gas after even discharging, cause the pollution to the atmospheric environment.
