Plasma active deodorization device

ZW-F type plasma active oxygen deodorization device, equipped with a unique collision absorption unit inside, intercepts and removes particulate matter in the odor; The multi-element gas collected by the odor collection system is subjected to a plasma active oxygen deodorization device. Under the action of a high-pressure plasma electric field, the ionized initial state oxygen ionizes and charges the odor ions for deodorization. The charged small ions (dust particles) are collected by the adsorption unit and flow into and deposit into the dust storage box of the gas treatment device. The harmful gases in the gas are sterilized by the ozone generated in the electric field, and the odor is removed. The harmful gases are removed, and the removal rate is tested to be over 90%. The clean air is discharged through the air outlet and meets the emission standards.

Product Details

based on experimental results and combined with data on the use of oxidation methods to treat odors abroad, the mechanism and main products of plasma purification equipment for treating various odor components have been basically determined. The main gas-phase pollutants contained in odorous pollutants include H2S, NH3, CH3SH, VOCs (organic compounds), etc.

There are two main ways for reactive oxygen species to remove the above-mentioned pollutants: one is to open the chemical bonds of certain harmful gas molecules under the instantaneous high-energy action of high-energy electrons, allowing them to directly decompose into elemental atoms or harmless molecules; The second is the oxidation and decomposition into harmless products under the action of a large number of high-energy electrons, ions, excited particles, oxygen radicals, and hydroxyl radicals (free genes have strong activity due to unpaired electrons).

The reaction mechanism is as follows:

H2S+O2, O2-, O2+→ SO3+H2O

NH3+O2, O2-, O2+→ NOx+H2O

VOCs+O2, O2-, O2+→ SO3+CO2+H2O

From the above reactions, it can be seen that the odor components will be transformed into small molecules such as NOx, SO3, H2O after equipment treatment. At a certain concentration, the conversion rate of various reactions is above 95%, and the odor concentration is low. Therefore, the concentration of the products is extremely low and can be accepted by the surrounding atmosphere.
