One,Plasma Waste Gas Treatment EquipmentIntroduction
Low-temperature plasma is the fourth state of matter after solid, liquid, and gas. When the applied voltage reaches the discharge voltage of the gas, the gas is ionized, forming a mixture including electrons, various ions, atoms, and free radicals. During the discharge process, although the electron temperature is high, the heavy particle temperature is low, resulting in the entire system being in a low-temperature state, hence the name low-temperature plasma. The degradation of pollutants by low-temperature plasma utilizes these high-energy electrons, free radicals, and other active particles to react with pollutants in the exhaust gas, causing the pollutant molecules to decompose rapidly and undergo subsequent reactions to achieve the goal of degrading pollutants. In general gas discharge, plasma is produced, and this discharge phenomenon is caused by a mechanism that separates one or more electrons from the gas or molecules, forming a gas medium, which is called ionized gas. If an external electric field generates ionized gas, conduction current is formed, and this phenomenon is known as gas discharge. This purification equipment technology is a principle for industrial waste gas treatment.
Low-temperature plasma purifier VOCs purification technology utilizes plasma generated by medium discharge to repeatedly strike gas molecules in waste gas at high speed, ionizing and cracking various components in the waste gas. Through a series of complex chemical reactions such as oxidation, it converts complex macromolecular pollutants into smaller molecular substances, or transforms toxic and harmful substances into non-toxic or low-toxic and low-hazardous substances.
Two,Plasma Waste Gas Treatment EquipmentPrinciple:
Low-temperature plasma degradation of pollutants involves the interaction of these high-energy electrons, free radicals, and other active particles with pollutants in the exhaust gas. This causes the pollutant molecules to decompose rapidly, followed by various subsequent reactions to achieve pollutant degradation. General gas discharges produce plasma, and this discharge phenomenon is the process by which one or more electrons are separated from the gas or molecules, forming a gaseous medium known as ionized gas. If an external electric field generates ionized gas, conduction current is formed, and this phenomenon is called gas discharge. This purification equipment technology is a principle of industrial exhaust gas treatment.

Electric field + electron → high-energy electron
2. High-energy electrons + molecules (or atoms) → excited atoms, excited groups, free radicals
3. Active group + molecule (atom) → product + heat
4. Active group + active group → product + heat
