1. Use extremely uneven electric field to form corona discharge and generate plasma. Under the action of electric field gradient, a large number of electrons and positive and negative ions contained in them collide inelastic with particulate pollutants in the air, thus adhering to them and becoming charged ions, which are collected by the dust collector under the action of external electric field force.
2. A large number of active particles in plasma are used to directly decompose and remove toxic, harmful and refractory pollutants. This technology is mainly realized in two ways: one is to open the chemical bonds of some harmful gas molecules under the instantaneous high energy of high-energy electrons, so that they can be directly decomposed into simple atoms or harmless molecules; Second, it is oxidized and decomposed into harmless products under the action of a large number of high-energy electrons, ions, excited particles, oxygen free radicals and hydroxyl free radicals (free genes and unpaired electrons have strong activity).
3. The negative ions are generated by electric discharge, and the negative ions diffuse into the indoor space driven by ion wind. On the one hand, proper concentration of negative ions can adjust the ion balance in the air. On the other hand, it can effectively remove pollutants in the air. High-concentration negative ions collide with toxic chemicals and bacterial suspended particles in the air to make them negatively charged. These negatively charged particles will attract positively charged particles (usually bacteria, viruses, babies, etc.). Positively charged in the air). This accumulation process continues until the particles are heavy enough to land on the ground.
