Abstract

The invention discloses a VOC (volatile organic compound) treatment system adopting ozone and micro-nano-bubbles. The system comprises a waste gas treatment device, a spray liquid circulating filtration device, a micro-nano-bubble generation device and an ozone generation device, wherein the waste gas treatment device comprises a waste gas inlet, a waste gas purification chamber and a waste gas outlet; an axial flow fan, a gas-water separator and a micro-nano-bubble water mist spray nozzle are arranged in the waste gas purification chamber sequentially from top to bottom. The system adopts the ozone and the micro-nano-bubbles to degrade VOCs, a treatment method is safer than other treatment methods, the operation is convenient, and the treatment cost is low; the VOC removal rate can be higher than 96% by the aid of optimization selection of a spray liquid and mutual actions of the ozone generation device, the micro-nano-bubble generation device and the spray nozzle.

Description

technical field [0001] The invention relates to the technology in the field of waste gas treatment, in particular to a VOC ozone micro-nano bubble treatment system. Background technique [0002] Marked by the General Office of the State Council forwarding the "Guiding Opinions on Promoting Joint Prevention and Control of Air Pollution to Improve Regional Air Quality" issued by the Ministry of Environmental Protection and other departments, my country's volatile organic compound (VOC) pollution is controlled after sulfur dioxide, nitrogen dioxide and PM10. From behind the scenes to the front of the stage, stepping into the main battlefield of environmental protection work. At present, domestic VOC treatment equipment is mainly based on regenerative combustion method and catalytic oxidation method, both of which require high temperature treatment, which is extremely risky and has high input costs. In recent years, VOC processing systems have been improved in different ways, bu...
