Method for processing organic waste gas through optical microwave catalytic oxidation

Abstract

The invention discloses a method for processing organic waste gas through optical microwave catalytic oxidation. The method comprises the following steps: spraying an alkaline solution to a corrugated plate to form a liquid membrane, contacting the organic waste gas with the liquid membrane to carry out physical dissolution and chemical reactions to complete a pretreatment; screen-filtering the pretreated organic waste gas, then carrying out microwave radiation on the organic waste gas so as to break down the molecular chains of the organic waste gas for the first time; utilizing high-energy C-wave band ultraviolet lights to radiate the organic waste gas to break down the molecular chains of the organic waste gas for the second time; carrying out first oxidation on the organic waste gas by hydroxyl free radicals; then carrying out second oxidation on the organic waste gas by ozone which is generated by high-ozone HV ultraviolet light beams; and finally making the deodorized and sterilized organic waste gas go through a rare-earth oxide catalyst taking titanium dioxide as the honeycomb carrier to carry out third catalytic oxidation. The method can effectively completely decompose and crack the high-molecular pollutants and high-molecular pollutant molecular chains, and then catalytically oxidizes and converts the high-molecular pollutants into low-molecular harmless substances. Moreover, the catalytic oxidation speed is accelerated, the processing time is shortened, and the electric energy is saved.

Description

Technical field [0001] The invention relates to a method for treating organic waste gas, in particular to a method that utilizes light microwave radiation and catalytic [0002] Chemical oxidation treatment of industrial organic waste gas.

[0003] There are still some problems in the treatment of high-concentration organic waste gas produced in pharmaceutical, leather, metallurgy, coking and other industries. It will pollute the air and endanger human health; in addition, the treated organic waste gas cannot be effectively transformed and utilized, resulting in a waste of resources to some extent

With the development of science and technology, the treatment of industrial harmful organic waste gas began to adopt new optical microwave treatment technology. Compared with the traditional method of treating organic waste gas, it has achieved better technical results in all aspects, especially the treatment effect has been significantly improved. However, the power consumption in the processing process is relatively large, and the energy-saving effect is not good enough.
