System and method for treating gases containing VOC

Abstract

The invention relates to a system and a method for treating gases containing VOC and in particular relates to a system and a method for treating gases containing VOC. According to the system and the method, any oxidant does not need to be added, and the treatment cost is low. According to the device, molecular bonds of organic compounds are broken by utilizing a local high-temperature high-pressure environment generated during nanoscale bubble bursting, and the aim of degrading the VOC in the gases is achieved. According to the system and the method, any oxidant does not need to be used in the VOC degradation process, and only water is needed to take participate in the total decomposition process; and moreover, the recycled water can participate in the treatment process of the gases containing the VOC again in a circulation water device through the steps such as filtering, and loss is avoided. Due to the absence of the other oxidants, the influence on the environment and a human body is avoided, and the treatment burden of a discharger is greatly alleviated.

Description

【Technical field】 [0001] The invention relates to a treatment system and method for VOC-containing gas, in particular to a treatment system and method for VOC-containing gas that do not need to add any oxidant and have low treatment cost. [0002] 【Background technique】 [0003] VOC substances refer to the general term of organic substances that are easily volatile at room temperature, and common ones include formaldehyde, toluene and xylene. The traditional spraying industry uses a large amount of nitro lacquer raw and auxiliary materials in the process of product spraying. The nitro lacquer raw and auxiliary materials contain a large amount of organic solvents, especially the aromatic hydrocarbons contained in highly volatile solvents such as xylene, toluene, and benzene. It is also flammable and highly volatile into the environment, causing a large number of VOCs to be discharged into the atmosphere, polluting the atmosphere and endangering human health. [0004] ...

AI Technical Summary

Problems solved by technology

[0005] Chinese patent CN01138636 discloses a treatment equipment and treatment method for VOC organic waste gas. This patent integrates ozone oxidation technology and traditional wet scrubbing technology, and uses oxidants (especially hydrogen peroxide) to treat VOC waste gas. This treatment method requires a large amount of Hydrogen peroxide, the processing cost is high, and the inhalation of hydrogen peroxide vapor or mist is strong to the human respiratory tract. Direct contact with the liquid can cause irreversible damage or even blindness. Once there is a mistake in the operation process, it will have an immeasurable impact

Moreover, this treatment method sometimes requires repeated treatment of the gas containing VOC, which increases the treatment cost and reduces the treatment efficiency, which virtually increases the burden on the enterprise.
