Waste gas purifying method for textile printing and dyeing setting machine and complete equipment thereof

Abstract

The invention discloses a waste gas purifying method for a textile printing and dyeing setting machine and complete equipment thereof, relates to the technical field of textile and also relates to the technical field of waste gas purification. After cotton velvet in waste gas is separated by a cotton velvet separation device, waste gas is subjected to heat energy recovery by a heat energy recovery device, is subjected to oil removal by an oil-gas separation device, is purified by a gas purification device and finally is discharged. The waste gas purifying method for the textile printing and dyeing setting machine and the complete equipment thereof has the excellent characteristics that the waste gas purifying method and the complete equipment thereof are simple and convenient to operate, have no hazard and are safe and reliable; the complete equipment has corrosion resistance and temperature resistance; the cost is saved; the occupied area is small; the service life is long; wastewater is recycled; the investment and the operation cost of the equipment are low; the efficiency of degreasing, removing dust and collecting oil is high; and the like. Therefore, the finally discharged gas meets the requirements of environmental-friendly discharge.

Description

technical field [0001] The invention relates to the technical field of textiles, and also relates to the technical field of waste gas purification. Background technique [0002] The exhaust gas emitted by the textile printing and dyeing sizing machine not only contains a lot of smoke and dust, but also contains polyphenylene organic matter, printing and dyeing auxiliaries, lint, oil and other components. Each sizing machine generally emits 150-250 mg / m of particulate matter 3 , soot 40-80mg / m 3 . With the increase of production, the oil, smoke and dust discharged are very harmful to human health and the environment, and the pollution problem caused by the exhaust gas emission of the setting machine has become more and more acute. The fume in the exhaust gas of the sizing machine comes from the chemical fiber oil in the cloth volatilized during the high-temperature sizing of the sizing machine and the chain oil lubricated by the sizing machine, including phosphate esters an...

AI Technical Summary

Problems solved by technology

This method cannot achieve complete separation. The upper layer of water still contains a large amount of oil and dirt, and the filling of the lower layer will still cause soil environmental pollution. Therefore, this technology can no longer meet the needs of environmental protection.

In addition, because the exhaust gas is high-temperature gas, the existing technology cannot make full use of the heat energy in the high-temperature gas, which is not conducive to saving production.
