Abstract

The invention discloses a high temperature organic solvent exhaust-gas treatment apparatus, which comprises a first stage separation unit for first stage separation of organic exhaust gas; a second stage separation unit which is connected with the first stage separation unit, and is used for carrying out a second grade separation of the organic exhaust gas which is treated by the first stage separation; a third stage filtering unit which is connected with the second stage separation unit, and is used for carrying out a third stage filtering treatment of organic exhaust gas which is treated by the second stage separation. According to the invention, the organic exhaust gas discharged in the processing process of printing, coating and baking varnish industries can be recycled and utilized, thereby minimizing air pollution, minimizing environment pollution and improving energy utilization rate.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a high-temperature organic solvent waste gas treatment device specially used in printing, coating and paint baking industries. Background technique [0002] At present, the promotion of energy conservation and emission reduction and the development of a low-carbon economy have become the main theme of world economic development. Especially for a large developing country such as my country, which is relatively short of per capita resources and seriously damaged by ecological environment, under the huge pressure of energy and the environment, promoting It is imperative to save energy and reduce emissions and develop a low-carbon economy. For industries such as printing, coating and baking paint, a large amount of organic solvents are used in the printing and coating process, and a large amount of high-concentration organic waste gas is discharged. The volatilization of ...
