Section 1: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, creating 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 within a short time and undergo subsequent reactions to achieve pollution degradation. Generally, gas discharge produces plasma, and this discharge phenomenon is achieved by a mechanism that separates one or more electrons from the gas or molecules, forming a gaseous medium known as ionized gas. If the external electric field generates ionized gas, the conduction current is formed, and this phenomenon is called gas discharge. This purification equipment technology is a principle of 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 cleaving various components in the waste gas. Through a series of complex chemical reactions, such as oxidation, it converts complex macromolecular pollutants into smaller molecules or transforms toxic and harmful substances into harmless or low-toxicity and low-hazard substances.
