The invention relates to an exhaust purification treatment method and device. According to the invention, a superoxide radical generation process as well as an exhaust oxidation and decomposition process are carried out separately, so that harmful components in the exhaust are prevented from being directly contacted with a superoxide radical generator so as not to cause catalyst deactivation, high efficiency and energy-saving property of the device are achieved, and the method and the device are especially suitable for exhaust with high contents of volatile organic pollutant and sulphur element. According to the method, automatic processing, cyclic utilization as well as automatic mixing of spray liquid are realized in a spraying process, and the problems of secondary pollution and water consumption in the traditional method are solved. All units of the device are designed reasonably and are integrated highly, the whole exhaust treatment process can be controlled automatically, the treatment efficiency is high, and the treatment effect can be guaranteed.
Description
technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas purification treatment method and device. Background technique [0002] Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before being discharged to the outside, so as to meet the national standards for external discharge of waste gas. General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment and air sterilization, disinfection and purification. [0003] Common exhaust gas treatment methods include activated carbon adsorption method, catalytic combustion method, chemical washing method, acid-base neutralization method, plasma method, photocatalytic oxidation method, etc. For example, the treatment methods of organic waste gas include condensation recovery method, adsorption method, catalytic combustion met...
