Problems solved by technology

Its disadvantages are as follows: the oxidation catalyst used is hydrogen peroxide, hydrogen peroxide is an aqueous solution of hydrogen peroxide, its oxidation potential is 0.87, the oxidation is limited, and the treatment effect is limited; in addition, hydrogen peroxide cannot be self-sufficient and needs to be purchased, and the entire system uses a large amount. The treatment cost is high; in order to enhance the treatment effect, multiple catalytic oxidation spraying equipment will be used, which will increase equipment investment and reduce economic efficiency

Embodiment Construction

[0010] The present invention will be described below with reference to the drawings and embodiments.

[0011] Such as figure 1 As shown, an exhaust gas oxidation treatment system of the present invention includes an exhaust gas collection area 1, an oxidation spray tower 2, a catalytic oxidation tower 3, an acid-base neutralization tower 4, an exhaust fan 5, and a chimney. The oxidation spray tower 2 consists of There are defogging layer, spray layer, filler layer and aeration layer from top to bottom. The aeration layer is composed of several aeration discs. The ozone outlet of the ozone generator 6 communicates with the aeration layer in the oxidation spray tower 2. The exhaust gas outlet of the exhaust gas collection zone 1 is connected to the inlet of the oxidation spray tower 2 through the exhaust pipe, and the outlet of the oxidation spray tower 2 is connected to the inlet of the catalytic oxidation tower 3 through the exhaust pipe. The outlet of the catalytic oxidation tow...

Abstract

The invention discloses a waste gas oxidation treatment system which comprises an ozone generator. A demisting layer, a spray layer, a packing layer and an aeration layer are arranged in an oxidation spray tower from top to bottom, the aeration layer consists of a plurality of aeration disks, an ozone outlet of the ozone generator is communicated with the aeration layer in the oxidation spray tower, a plurality of packing layers are arranged in a catalytic oxidation tower, main packing includes catalysts, and a demisting layer, a spray layer and a packing layer are arranged in an acid-base neutralization tower from top to bottom. Compared with the prior art, the waste gas oxidation treatment system is more thorough in waste gas treatment, better in effect and lower in cost.

Description

Technical field [0001] The invention relates to an exhaust gas treatment system, in particular to an exhaust gas oxidation treatment system. Background technique [0002] Chemical, pharmaceutical, food, papermaking, fertilizer, printing and dyeing, spraying, iron and steel, garbage disposal and other industries all produce organic waste gas and inorganic waste gas during the production process, which are discharged into the atmosphere, which will seriously affect the quality of the atmosphere and cause serious pollution to the surrounding environment . [0003] In the prior art, the system for treating exhaust gas includes an exhaust gas enclosed area connected end to end, a catalytic oxidation spray tower, an acid oxidation spray tower, an alkaline neutralization tower, and a high-pressure fan, a catalytic oxidation spray tower, and an acid oxidation spray tower. The tower and the alkaline neutralization tower are respectively equipped with air filters containing catalytic oxidan...
