Equipment introduction:
UV photocatalytic waste gas treatment equipment can adapt to the deodorization and purification treatment of high concentration, atmospheric volume and different industrial waste gas. It can work continuously 24 hours a day, with stable and reliable operation, no mechanical action, no noise, no special management and daily maintenance. It only needs regular inspection. The equipment has low energy consumption, low equipment wind resistance, and can save a lot of exhaust air. Photocatalysis waste gas treatment equipment covers a small area, has light self weight, and is suitable for compact layout and special site conditions; high quality imported materials manufacturing: high fire and corrosion resistance, safe and stable equipment performance, made of stainless steel or PP, with service life of more than 15 years.
Scope of application:
It is suitable for deodorization and purification of odorous gas in oil refineries, rubber plants, chemical plants, pharmaceutical plants, sewage treatment plants, waste transfer stations, slaughterhouses, feed plants, etc. the source of odorous gas in landfills and the odor pollution of landfills are formed. The substances contain the odorous smell from "odorous groups", which is harmful to the body.
working principle:
UV photolysis this equipment is divided into UV photolysis area + plasma decomposition area + activated carbon cotton net, which can decompose and purify the organic waste gas by plasma. The odor gas will be purified by UV photolysis before entering the plasma decomposition area. After multiple purification, it will be discharged up to the standard!
Under the action of the external electric field, the dielectric discharge produces a large number of energy carrying electrons to bombard the pollutant molecules, making them ionize, dissociate and excite, causing a series of complex physical and chemical reactions, making the complex macromolecular pollutants turn into simple and small molecule safe substances, or turning the harmful substances into harmless or low harmful substances, so that the pollutants can be degraded and removed.
Technical advantages:
1. Dielectric barrier discharge (DBD) produces high electron energy and high density of low-temperature ionomer, which is 1500 times higher than that of common plasma technology (corona discharge). It can break almost all molecular chains of organic waste gas.
2. The technical reaction speed is fast, and the flow rate of gas through the reaction zone reaches 3-15ms, which can also achieve good treatment effect.
3. High degree of automation, the equipment starts and stops very quickly and starts when it is used. For some collection points with discontinuous waste gas, it can start and stop circularly to save costs.
4. In the process of plasma chemical reaction, the energy transfer in the process of plasma chemical energy transfer is roughly as follows:
1) electric field + electron → high energy electron
2) high energy electron + molecule (or atom) → (stimulated atom, stimulated group, free group) active group
3) active group + molecule (atom) → product + heat
4) active group + active group → product + heat
Technical features of UV photocatalytic equipment:
1. No side effects. It completely surpasses the traditional air purifier such as ozone. It can continuously sterilize and remove dust in the presence of people. It can intercept and kill all kinds of bacteria in the air widely. The test shows that the killing rate of colony bacteria, Staphylococcus aureus, Bacillus subtilis, black variety spore and natural bacteria is over. 9%, and the inhalable particles are effectively removed, reaching a cleanliness of 10000-100000.
2. Eliminate the peculiar smell of polluted and harmful gases, accelerate the initial electrons in the electric field, and impact the oxygen molecules in the air. When the energy exceeds the ionization potential of the oxygen molecule, the oxygen molecule ionizes rapidly. The oxygen molecules losing electrons become positive oxygen ions (O2 +, while the released electrons combine with another neutral oxygen molecule to become negative oxygen ions (O2 -). As a result, the oxygen ions differentiate and absorb the intermediate oxygen molecules to form oxygen groups such as O2 +, O2 -, O2, etc., which have strong oxidizability and can oxidize and decompose the harmful components in the polluted air into harmless ones in a short time Products and water.
It has been proved that most of the harmful substances in the polluted air with a certain concentration can be oxidized and decomposed in a short time, and the average conversion rate is over 90%
