Embodiment 1

[0029] The embodiment provides an advanced oxidation system capable of generating multiple free radicals for processing organic waste gas and malodorous gas ( Figure 1~Figure 3 ), which includes:

[0030] Air supply duct 2, air supply duct 2 select a specific diameter according to a specific air volume, and select a specific material according to different working conditions;

[0031] Equipped with a certain concentration of persulfate solution tank 3, the persulfate solution is used to produce persulfate 4 - ·Sodium persulfate is generally used as SO 4 - ·Generation source, the concentration of persulfate solution is generally 4-20g / L according to the type and concentration of waste gas;

[0032] The 254nm UV lamp 4 is used to activate the persulfate to generate a certain amount of free radicals. The number of the 254nm UV lamp 4 is determined according to the amount of the persulfate solution; the 254nm UV lamp is made of waterproof material and has stronger penetration ability fo...

Abstract

The invention discloses an advanced oxidation system for treating organic waste gas and malodorous gas. The system comprises a reactor body, a persulfate solution tank, 254nm ultraviolet lamps and vacuum ultraviolet low-pressure mercury lamps; the persulfate solution tank is arranged at the bottom of the reactor body, an air supply pipeline extends into the bottom of the persulfate tank from outside of the reactor body, a plurality of 254nm ultraviolet lamps are vertically arranged in the persulfate solution tank, the 254nm ultraviolet lamps are arranged on a 254nm ultraviolet lamp fixing plate with a plurality of vent holes, two vacuum ultraviolet low-pressure mercury lamp fixing plates with a plurality of vent holes are arranged above the 254nm ultraviolet lamp fixing plate at intervals,a plurality of vacuum ultraviolet low-pressure mercury lamps are vertically arranged between the two vacuum ultraviolet low-pressure mercury lamp fixing plates, and the top of the reactor body is provided with an air outlet. The oxidation system can produce OH, SO4, and O free radicals, thereby shortening the time for degrading organic pollutants and increasing the types of waste gas treated by the oxidation system.

Description

Technical field [0001] The invention belongs to the technical field of waste gas treatment, and particularly relates to an advanced oxidation system for treating organic waste gas and malodorous gas. Background technique [0002] With the continuous development of my country's industry and the improvement of people's quality of life, the problem of industrial organic waste gas has risen to a very serious level. How to solve industrial waste gas has now attracted widespread attention from the society. The mainstream technologies for treating low-concentration industrial waste gas mainly include advanced oxidation, plasma, combustion, absorption, adsorption, and so on. The advanced oxidation method stands out due to its safety, mild operating conditions, and economy. [0003] Advanced oxidation technology has always been the focus of domestic and foreign research in the treatment of pollutants. Advanced oxidation methods use free radicals to degrade organic pollutants or directly mi...
