System and method for treating toxic gas by using electrically coupled plasma

Abstract

The invention discloses a system and method for treating toxic gas by using electrified coupled plasma. The system comprises a Plasma generating device, a Plasma voltage regulator, a purifying device, a gas inlet channel and a gas detecting device; the Plasma generating device is used for generating plasmas; and the purifying device is positioned in the Plasma generation device and is used for purifying toxic gas. The method comprises the following steps: adjusting the Plasma voltage regulator to generate plasmas inside the Plasma generating device; enabling toxic gas molecules to form various tiny particles under the action of the plasma, and enabling the tiny particles to react with the purification device; enabling the gas detection device to detect the gas discharged by the Plasma generation device and determining whether the gas is discharged or not. Through the ionization effect, toxic gas molecules are broken down to form tiny particles which react with the purification device, the purpose of effective purification treatment is achieved, and a technical reference is provided for purification treatment of other toxic gases.

Description

technical field [0001] The invention relates to the field of electrochemistry, in particular to a system and method for treating poisonous gas with electrically coupled plasma. Background technique [0002] The phenomenon of global warming caused by the greenhouse effect is becoming more and more serious. Compared with the traditional understanding of the greenhouse gas CO 2 , the fluoride gas has a higher greenhouse effect potential value, and the fluoride gas is not easy to decompose, and the resulting greenhouse effect will continue to increase for a long time, which will have a great impact on the natural environment and human life. [0003] At present, for such toxic pollutant gases, lye or Al 2 o 3 Adsorption, or use calcium and / or magnesium as the active ingredient of the purifier, or use metal zinc, metal aluminum or a mixture of the two as the main ingredient of the purifier. However, since such gases are chemically stable at room temperature, even under the acti...

Problems solved by technology

However, the above method is cumbersome and consumes a lot of electric energy. At the same time, because the chemical properties of these purifying agent components are active, they are easy to chemically react with oxygen or water during the high-temperature purification process. When the reaction purification agent is post-treated, there is a risk of rapid heat release and harmful gas generation.

Traditional treatment methods generally have problems such as unsatisfactory treatment effect, low efficiency, complicated process, time-consuming, and high energy consumption. There is an urgent need for a system and method that can simply and effectively purify such toxic gases and even various toxic gases.
