Working principle of plasma photocatalytic integrated machine:
When the exhaust gas enters the plasma photolysis integrated purification equipment, it first undergoes a plasma chemical reaction process, where electrons first obtain energy from the electric field and transfer it to molecules or atoms through excitation or ionization. The molecules or atoms that obtain energy are excited, while some molecules are ionized, thus becoming active groups; Afterwards, these active groups collide with molecules or atoms, as well as with each other, to generate stable products and heat. Under the action of an external electric field, a large number of energy carrying electrons generated by dielectric discharge bombard pollutant molecules, causing them to ionize, dissociate, and excite. This then triggers a series of complex physical and chemical reactions, transforming complex large molecule pollutants into simple small molecule safe substances, or transforming toxic and harmful substances into non-toxic, harmless, or low toxicity substances, thereby enabling pollutants to be degraded and removed
Then, some of the organic waste gas is further decomposed, decomposed, and catalytically oxidized to decompose the pollutant gas into non-toxic, harmless, and odorless gases. By using high-energy C-band light to strongly crack the molecular chains of polluted gases, the molecular structure of substances is changed, and high molecular pollutants are cracked and oxidized into low molecular weight harmless substances such as water and carbon dioxide. O3 strong catalytic oxidant for exhaust gas catalytic oxidation can effectively kill bacteria, destroy and transform toxic and harmful substances into low molecular weight harmless substances. Stimulate the catalyst coating with C-band laser to generate activity and enhance catalytic oxidation. During the decomposition process, high-energy and high ozone UV beams are generated to decompose oxygen molecules in the air, producing free oxygen, also known as reactive oxygen species. Due to the imbalance of positive and negative electrons carried by free oxygen, it needs to combine with oxygen molecules to produce ozone. UV+O2 → O -+O * (reactive oxygen species) O+O2 → O3 (ozone). It is well known that ozone has a strong oxidizing effect on organic matter and has a strong cleaning effect on odorous gases and other irritating odors. O3 is also a strong catalytic oxidant for exhaust gas catalytic oxidation, which breaks down the molecular bonds of bacteria in odorous gases, destroys their nucleic acid (DNA), and then undergoes oxidation reaction through ozone to completely achieve the purpose of deodorization and sterilization.
