Low-temperature plasma device for mercury-containing waste gas treatment and treatment system

Abstract

The invention discloses a low-temperature plasma device for mercury-containing waste gas treatment and a treatment system, and relates to the technical field of mercury-containing pollutant treatment.The low-temperature plasma device combines a carbon nano functional material with the low-temperature plasma device, and the carbon nano functional material is plated on the surface of the inner wall of a reactor, so that the surface of an electrode is protected from being damaged by ablation; and meanwhile, by utilizing the field electron emission effect of the carbon nanomaterial under high voltage, the formation of low-temperature plasma is promoted, the energy density in the reactor is enhanced, the pollutant treatment efficiency of the reactor is improved, and the energy cost is saved. Under a corresponding mercury pollution treatment process, the mercury removal effect can reach 99% of mercury deep purification of a single-stage reactor.

Description

technical field [0001] The invention relates to the technical field of mercury-containing pollutant treatment, in particular to a low-temperature plasma device and a treatment system for mercury-containing waste gas treatment. Background technique [0002] Low temperature plasma technology has been used to treat a variety of pollutants, such as mercury, dioxins, etc. The core of its technology is to use a specific power source to generate low-temperature plasma in the reactor, and the pollutants pass through and undergo an electrochemical reaction of the plasma, so as to achieve the effect of treating the pollutants. For mercury-containing waste gas, the principle is to oxidize mercury through high-energy low-temperature plasma, so that the original mercury that is difficult to absorb and separate is converted into oxidized mercury that is easy to be absorbed by liquid, so that it is easier to achieve separation in subsequent absorption devices. removal effect. For VOCs su...

AI Technical Summary

Problems solved by technology

Different cylinders, electrode types and different distribution structures will affect the actual treatment of pollutants

[0004] Although there are many types of reactors, there is often a disadvantage, that is, once the reactors and electrodes are manufactured, it is difficult to disassemble them.

When a part of the reactor is damaged, it is difficult to repair the part, and the whole reactor can only be discarded

[0005] In addition, when it is necessary to modify and modify the inner wall of the reactor, it is difficult to modify the surface of the inner wall due to the closed and closed inner wall of the traditional cylindrical reactor, which leads to the limitations of the traditional reactor.
