Application of ozone catalyst in corona industrial waste gas treatment

Corona treatment is a kind of electric shock treatment, also known as electric shock machine, electric discharge machine. By adding high frequency and high voltage power supply (high frequency AC voltage up to 5000-15000V/m2) between the discharge electrode and the corona treatment roller (generally high temperature resistant, ozone resistant, high insulation silicone rubber roller)

When the voltage exceeds the ionization resistance of 1-2mm air gap, continuous discharge will occur, so that the air is ionized, forming a large amount of ozone, oxidizing the molecules on the surface of the plastic, producing carbonyl compounds, peroxide compounds, etc. Purple spark.

All kinds of plasma produced after air ionization accelerate the impact on the surface of the film under the action of strong electric field, so that the chain molecules are broken, and the free radicals and the air corona products are oxidized cross-chain reaction.

Due to the working principle and characteristics of the corona machine, it will produce a high concentration of ozone. First of all, ozone is also a pollutant. Specifically, it has a strong oxidation, can strengthen the surrounding objects, when reached a certain concentration, will cause harm to the human body. In some industry standards and occupational health exposure limits, there are corresponding clear emission standards. Therefore, it is necessary to treat the ozone generated by the corona machine to avoid the impact on the human body and the surrounding environment.

In the face of corona ozone exhaust gas, the solution is to use ozone decomposition catalysts to rapidly reduce ozone to oxygen. Therefore, it is only necessary to add a catalytic chamber to the discharge of corona gas. The catalyst has long service life, easy installation, and can run effectively for a long time.
