Abstract

The invention relates to an atmospheric pollutant treatment technology which comprises the steps: A) gas feeding: inflating waste gas to be treated into a waste gas pretreatment device; B) flock removal: making the waste gas pass through an automatic flock removing mechanism to remove flocks in the waste gas; C) heat exchange: making the flock removed waste gas pass through a gas-liquid heat exchange mechanism to exchange heat with the gas-liquid heat exchange mechanism to reduce the temperature of the waste gas; D) wax removal: making the heat exchanged waste gas pass through a wax and impurity removing mechanism to remove wax in the waste gas; E) primary deodorization: making the wax removed waste gas pass through a primary microbubble deodorizing mechanism to primarily deodorize the waste gas; F) electrostatic adsorption: inflating the primarily-deodorized waste gas into a purifying tower from bottom to top and removing lamp black and particles in the waste gas through an electrostatic adsorption device; G) deep deodorization: making the electrostatically-adsorbed waste gas pass through a micro-nano bubble deep deodorizing mechanism from top to bottom to achieve deep deodorization; H) terminal treatment: making the deep-deodorized waste gas pass through a terminal white steam removing mechanism from bottom to top to remove white steam; I) discharge.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an air pollutant treatment process. Background technique [0002] The 140°C-170°C waste gas emitted by the printing and dyeing setting machine not only contains a lot of smoke and dust, but also contains polyphenylene organic matter, printing and dyeing auxiliaries, grease, wax, and pungent odors. Particles in the waste gas emitted by the setting machine The concentration is 150-250mg / m3, and the concentration of lampblack is 40-80mg / m3. The particulate matter, oil fume and pungent odor emitted by the printing and dyeing sizing machine are extremely harmful to human health and the environment, and the pollution caused by the exhaust gas emitted by the sizing machine is becoming more and more acute. [0003] At present, the main methods of exhaust gas treatment of stereotypes machines in the printing and dyeing industry and the problems encountered by enterprises in the process of...
