Integrated treating apparatus and treating process for exhaust gas of setting machine used in dyeing and finishing industry

Abstract

The invention discloses an integrated treating apparatus for exhaust gas of a setting machine. The integrated treating apparatus comprises a spray condensation unit, a wet static oil removing unit, a flue gas discharging unit, an electric control unit and a water treatment unit. The spray condensation unit, the wet static oil removing unit and the flue gas discharging unit are successively connected; the water treatment unit is connected with the wet static oil removing unit and used for treating and recycling waste water produced during treatment of the wet static oil removing unit; and the electric control unit comprises a variety of electric control facilities like an anemometer, a flowmeter and a liquidometer and is used for real-time monitoring and automatic control of each unit of the whole apparatus. According to the invention, water spraying technology and static treatment technology are integrated together instead of simple combination, so integrated wet static technology is realized, the removal rates of particles and oil smoke are increased, ultra-low emission of the oil smoke and the particles is realized, and fire risks brought by dry static treating technology are eradicated; thus, almost zero release is actually realized.

Description

technical field [0001] The invention belongs to the field of waste gas treatment, and in particular relates to an integrated treatment device for waste gas of a setting machine in the dyeing and finishing industry and a process thereof. Background technique [0002] The exhaust gas emitted by the printing and dyeing sizing machine not only contains a lot of smoke and dust, but also contains polyphenylene organic matter, printing and dyeing auxiliaries, grease and wax, etc. The concentration of particulate matter in the sizing machine exhaust gas is 150~250mg / m 3 , the oil fume concentration is 40~80mg / m 3 . The emitted particles and fumes are very harmful to human health and the environment, and the pollution problem caused by the exhaust gas of the setting machine is becoming more and more acute. [0003] The common exhaust gas treatment technologies of setting machines include mechanical purification method, water spray treatment method, incineration purification method ...
