A vocs integrated processing device and method

Abstract

The invention discloses a VOCs integrated treatment device and method. The device comprises a VOCs collection pipe, an ozone generation assembly, a micro-nano-bubble generation assembly, a pretreatment assembly, a turbulent flow reaction assembly and an ozone destruction assembly; the ozone generation assembly is used for generating ozone gas, and the micro-nano-bubble generation assembly is usedfor generating active water containing micro-nano-bubbles; the pretreatment assembly is connected with the VOCs collection pipe and the micro-nano-bubble generation assembly, so that macromolecular VOCs are subjected to a melting reaction; the turbulent flow reaction assembly is connected with the ozone generation assembly and the pretreatment assembly; and a turbulent flow structure is arranged in the turbulent flow reaction assembly, and VOCs gas and ozone gas are fully mixed and react in a turbulent flow reaction bin through the turbulent flow effect. And the ozone destruction assembly is connected with the turbulent flow reaction assembly so as to decompose residual ozone gas. The device and the method have the advantages of high treatment efficiency, thorough treatment result, no secondary pollutants, simple raw materials, low treatment cost, wide application range and the like.

Description

technical field [0001] The invention relates to the technical field of organic pollutant degradation treatment, in particular to a VOCs integrated treatment device and method. Background technique [0002] VOCs is an abbreviation for volatile organic compounds. When the VOCs in direct contact with the human body reach a certain concentration, it will cause symptoms such as headache, nausea, vomiting, fatigue, and even convulsions, coma, and damage to the liver, kidneys, brain and nervous system, resulting in memory loss and other serious consequences. Industrial VOCs are characterized by a large number of pollutants and large emissions. There are many types of harmful gases in the actual industrial production process, mainly including sulfur oxides, nitrogen oxides, halides, carbon oxides, VOCs, etc. The gases that cause pollution to the atmospheric environment are called gaseous pollution. The mainstream treatment technologies in the world include UV photocatalysis techno...

AI Technical Summary

Problems solved by technology

[0003] Condensation treatment cannot effectively separate the waste gas emitted by high-risk objects such as smelting industry and firecracker industry, and requires secondary treatment; although combustion treatment has a better treatment effect, it cannot deal with low-concentration VOCs; dissolution and absorption treatment cannot remove VOCs Complete degradation only prevents VOCs from diffusing into the air and easily causing secondary pollution; although biological treatment is stable, it has high environmental requirements and is not widely applicable
