Abstract

The invention belongs to the field of gas treatment equipment, and particularly relates to a polyurethane spinning method. The adopted tail gas treatment device comprises a first slag removal tank anda first tail gas purification tank, wherein the tail gas is filtered through the first slag removal tank, and the filtered tail gas is conveyed to a first tail gas purification tank through a guide pipe for absorption. The invention is characterized in that a slag removing module and a collecting tank are arranged in the first slag removing tank, the slag removing module is arranged on the collecting tank; the slag removing module is used for filtering impurities in the tail gas, a gas floating module and a spraying module are arranged in the first tail gas purification tank; the gas floatation module is used for absorbing the waste gas which has been subjected to slag removal; the spraying module is used for conveying the absorbing liquid to the gas floating module; a filtering head is fixedly arranged on the inner wall of the slag removing cylinder; a slag removing plate is fixedly arranged at the bottom end of the slag removing cylinder, and a first opening is formed in the centerof the slag removing plate and is used for conveying impurities in the slag removing cylinder into the collecting tank; and the purification capacity of the organic volatile tail gas is improved.

Description

technical field [0001] The invention belongs to the field of gas treatment equipment, in particular to a polyurethane spinning method. Background technique [0002] Polyurethane is mainly formed by the polyaddition reaction of diisocyanate or polyisocyanate with dihydroxy or polyhydroxy compounds. It has excellent properties such as high elasticity, wear resistance, low temperature resistance, solvent resistance and aging resistance, so it is widely used in various fields of national economy. A large amount of volatile organic gases are produced in the polyurethane spinning process, which poses a threat to the life and health of the staff; among them, volatile organic gases refer to VOCs waste gas. [0003] VOCs waste gas is a common industrial waste gas in the chemical industry. It has complex components and contains a large amount of organic substances such as hydrocarbons, aldehydes, chlorinated hydrocarbons, etc. Most of the components are carcinogenic pollutants. If th...
