The acidification caused by the polluted atmosphere causes the damage of the ecological environment, and serious disasters frequently occur, which causes great loss to human beings.
The plasma waste gas purifier adopts the latest technical design of unique adsorption-decomposition-carbonization centrifugal air draft installation, adopts the design of standard modules and the like, and is a purifying device for treating organic waste gas by a dry method. The method changes the process technology of using the activated carbon material, does not need to regenerate the raw materials, does not need special people to take charge, does not produce secondary pollution, and is convenient to replace, maintain and maintain.
The plasma is a fourth state of matter following the solid, liquid, gaseous state, and when the applied voltage reaches the discharge voltage of the gas, the gas is broken down, creating a mixture of electrons, various ions, atoms, and radicals.

The main working principle of the plasma generator is that low voltage is boosted to positive high voltage and negative high voltage through a booster circuit, air (mainly oxygen) is ionized by the positive high voltage and the negative high voltage to generate a large amount of positive ions and negative ions, the number of the negative ions is larger than that of the positive ions (the number of the negative ions is about 1.5 times of that of the positive ions), so that tiny dust particles suspended in the air are carried out on the air through sterilized air with negative charges, pollutants are degraded mainly by using active particles such as high-energy electrons and free radicals and pollutants in waste gas, pollutant molecules are decomposed in a very short time, and subsequent various reactions are carried out to achieve the purpose of degrading the pollutants. In general, a gas discharge generates plasma, and the discharge phenomenon is that one or more electrons are separated from a gas principle or molecule through a certain mechanism to form a gas medium, which is called ionized gas, and if an external electric field generates ionized gas, a conduction current is formed, which is called gas discharge.
