Common waste gas purification includes factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas peculiar smell purification, acid-base waste gas purification, chemical waste gas purification and the like. The waste gas discharged from industrial production often has harmful influence on environment and human health, and before being discharged into the atmosphere, the waste gas is treated by adopting a purification measure so as to meet the requirements of waste gas discharge standards, and the process is called waste gas purification.
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.
In normal production process, the high temperature waste gas that generally discharges contains fibre class pollutant and organic waste gas, and some processes still have discharges such as auxiliary agent and oil wax, lead to fibre class impurity to have stronger adhesion, and the filter plate is held up fibre class pollutant earlier usually among the prior art in the discharge pipe, reduces the complexity of impurity, but this kind of mode very easily leads to the jam of filter plate, influences textile waste gas's discharge efficiency to the greasy dirt on its surface can accelerate the speed that the filter screen is blockked up.
