Embodiment Construction
[0018] The method for photo-microwave catalytic oxidation treatment of organic waste gas of the present invention is:
[0019] 1. The organic waste gas is pretreated first, using a two-stage vertical packing absorption tower, using lye as the spray liquid, and metal or ceramic corrugated plate packing as the dehydration device. When the liquid is sprayed on the packing, a liquid film is formed. Due to the action of the liquid film, the contact area of the organic waste gas and the spray liquid is enlarged and fully contacted. During the contact process, the liquid phase and the gas phase undergo a physical dissolution and chemical reaction process, thereby removing pollutant components in the organic waste gas. The use of fast and dynamic washing equipment greatly enhances the original atomization effect by more than 10 times, more effectively removes water-soluble inorganic gas, dilutes the concentration of organic waste gas, reduces safety hazards, neutralizes acid and alkali,...

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. Background technique [0003] There are still some problems in the treatment of high-concentration organic waste gas generated in the pharmaceutical, leather, metallurgical, and coking industries. For example, the toxic, odorous, and refractory gases cannot be removed well, and the treated gas is still It will pollute the air and endanger human health; in addition, the organic waste gas cannot be effectively transformed and utilized, which causes a waste of resources to some extent. With the development of science and technology, the treatment of industrial harmful organic waste gas has begun to adopt new optical microwave treatment technology. Compared with traditional organic waste gas treatment methods, better technical effects have been a...
