Embodiment Construction
[0017] The method for purifying acetone waste gas of the present invention mainly includes three parts: chemical oxidation, dehydration treatment and adsorption purification. The acetone waste gas first passes through the chemical oxidation washing tower to absorb and purify, then passes through the dehydrator to remove the water droplets in the air flow, and then the waste gas enters the adsorption tower for adsorption treatment before being discharged. The invention utilizes combined purification of chemical oxidation and adsorption purification to realize effective purification of acetone waste gas, and the purification rate reaches over 99%.
[0018] The purification method of acetone waste gas of the present invention may further comprise the steps:
[0019] (a) Pass the acetone waste gas into the chemical oxidation scrubber to carry out chemical oxidation absorption purification; the inlet concentration of the acetone waste gas is at 10g / m 3 Hereinafter, the chemical ox...

The invention belongs to the technical field of waste gas control, and relates to an efficient acetone waste gas purifying method. The method mainly comprises the three steps of chemical oxidation, dehydration processing and adsorption purification. Absorption oxidation purification is carried out on acetone waste gas through a chemical oxidation washing tower at first, then water drops in gasflow are removed through a dehydrater, and waste gas enters an adsorption tower to be subjected to adsorption processing, and then is exhausted. The acetone waste gas is purified by combining chemical oxidation and adsorption purification, the acetone waste gas is effectively purified, and the purification rate is more than 99%. The acetone waste gas purifying method has the advantages that the purification efficiency is high, the reaction conditions are mild, the running cost is low, the application range is wide, and no secondary pollution is produced. The acetone waste gas purifying method can be used for purifying acetone waste gas in the chemical pharmaceutical industry.
Description
technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to an efficient purification method for acetone waste gas. Background technique [0002] In recent years, smog and haze have occurred frequently in my country, and the problem of regional air compound pollution characterized by ozone, fine particulate matter (PM2.5), and acid rain has become increasingly prominent. Volatile Organic Compounds (Volatile Organic Compounds, VOCs), as an important precursor of PM2.5 formation, have attracted widespread attention at home and abroad. As an important organic solvent, acetone is widely used in petrochemical, pharmaceutical, leather, oil, paint and other industries. Because acetone is extremely volatile, acetone waste gas is produced in its production, transportation, use, and wastewater discharge. It has become a major air pollutant, and the environmental hazards caused by it have attracted more and more attention. ...
