Plasma photo-oxygen all-in-one purification equipment is a device specifically for removing toxic and harmful gases and malodorous gases. It is a combination of two types of equipment: plasma decomposed exhaust gas purifier + UV photolysis deodorized exhaust gas purifier. It combines the advantages of the two devices of plasma exhaust gas purifier and ultraviolet photocatalytic deodorant exhaust gas purifier. Combining UV photolysis technology to synergistically purify waste gas and odor! It has the characteristics of high efficiency, low operating cost, small equipment footprint, light weight, no mechanical action, and no noise. The purification efficiency of the plasma photolysis machine purification equipment is more than 95%.
等离子光氧一体机工作原理： 2.Plasma photo-oxygen integrated machine works:
When the exhaust gas enters the purification equipment of the plasma photolysis machine, it first undergoes a plasma chemical reaction process, that is, the electrons first obtain energy from the electric field, and the energy is transferred to the molecules or atoms by excitation or ionization. When excited, at the same time, some molecules are ionized to become active groups; after these active groups collide with molecules or atoms, active groups and active groups, they generate stable products and heat. (Under the action of an external electric field, a large number of energetic electrons generated by the dielectric discharge bombard the pollutant molecules, causing them to ionize, dissociate and excite, and then trigger a series of complex physical and chemical reactions to transform the complex macromolecular pollutants. It is a simple small molecule substance, or a toxic and harmful substance is converted into a non-toxic and harmless or low-toxic and low-toxic substance, so that the pollutants can be degraded and removed.)
Then part of the organic waste gas is decomposed into odorless gas through destruction, decomposition and catalytic oxidation. C-band light is used to strongly crack the molecular chain of the polluted gas, change the molecular molecular structure, and crack and oxidize the high-molecular pollutants into low-molecular harmless substances such as water and carbon dioxide. O3 strong catalytic oxidant performs catalytic oxidation of exhaust gas, which can effectively kill bacteria, destroy and change toxic and harmful substances into low-molecular harmless substances. The C-band laser stimulates the catalyst coating to produce activity, which strengthens the catalytic oxidation. During the decomposition process, high-ozone UV light beams are generated to decompose oxygen molecules in the air to generate free oxygen, that is, active oxygen. Due to the imbalance of the positive and negative electrons carried by the free oxygen, it needs to be combined with oxygen molecules to generate ozone. UV + O2 → O- + O * (active oxygen) O + O2 → O3 (ozone). It is well known that ozone has a strong oxidizing effect on organic substances, and has a strong elimination effect on malodorous gases and other irritating odors. O3 is also a strong catalytic oxidant for catalytic oxidation of exhaust gas, cracking the molecular bonds of bacteria in the malodorous gas, destroying the nucleic acid (DNA) of bacteria, and then performing oxidation reaction through ozone to achieve the purpose of deodorization and sterilization.
Plasma is composed of electrons, ions, free radicals, and neutral ion currents. The working state is a meteor shower-like conductive fluid, which is the fourth material form other than solid, liquid, and gaseous. The plasma generator as a whole remains electrically neutral and reliable. According to the temperature of ions, plasma is divided into thermal equilibrium plasma, non-equilibrium plasma and low temperature plasma.
Working principle of low temperature plasma purification:
When low-temperature plasma is used to decompose contaminated media such as oil mist and exhaust gas, high-energy ions in the plasma play a decisive role. Exhaust gas and malodorous gas pass through the plasma electric field region. In the nanosecond time range, meteor rain-like high-energy ions collide with molecules (principle) in the medium inelastically. Plasma violently bombards pollutant molecules such as exhaust gas and odor, generating fission decomposition The energy is converted into the internal energy of the ground-state molecules (atoms), and a series of processes such as excitation, dissociation, and ionization make the contaminated medium in an active state. The contaminated medium generates high concentration, high intensity, and high energy under the action of the plasma. A variety of active free radicals, high-energy electrons, high-energy ions, etc. At the same time, a large amount of ozone, atomic oxygen, ecological oxygen and other mixed gases are generated, and a series of complex differentiation and redox reactions are performed. (Primary electrons are accelerated in an electric field, hitting oxygen molecules in the air. When the energy exceeds the ionization potential of the oxygen molecules, the oxygen molecules are rapidly ionized. The oxygen molecules that have lost electrons become positive oxygen ions (O2 +), and the released electrons In combination with another neutral oxygen molecule, it becomes a negative trophic ion (O2-). As a result, the oxygen ion polarizes and adsorbs the neutral oxygen molecule to form an ion group, such as O2 +, O2-, and O2. The oxidizing property can decompose harmful components in polluted air into harmless products and water in a short time.) From the perspective of purifying air efficiency, we chose a high corona current device to use pulsed corona discharge low temperature plasma. The principle of combining gas and adsorption technology eliminates harmful gases. The low-temperature plasma is mainly used to remove hydrogen sulfide, ammonia, benzene, xylene, formaldehyde, acetone, urethane, resin, and other gases. Used to remove carbon dioxide and ozone by-products. The purification device is composed of the low-temperature plasma generator of the primary filtering unit, the filtering unit, the fan and other equipment and components.
uv光氧净化的工作原理： 3. UV light oxygen purification works:
After entering the integrated equipment, the exhaust gas and malodorous gas pass through the UV beam area, and are irradiated by the ultraviolet light with a high energy rate, and a photolysis reaction occurs instantly, opening the chemical bonds of the exhaust gas and odorous pollutant molecules, destroying their molecular structure and nucleic acids; using ultraviolet rays Light waves decompose oxygen molecules in the air to generate free oxygen, that is, active oxygen. Due to the imbalance of the positive and negative electrons carried by free oxygen, they need to combine with the oxygen molecules, and then generate ozone, so that the pollutant molecules in the free state and ozone are oxidized to form a small one. Molecularly harmless or less harmful compounds. Such as CO2, H2O, etc. UV + O2 → O- + O * (active oxygen) O + O2 → O3 (ozone);
UV ultraviolet photolysis and plasma decomposition synergistically produce a series of photolysis and decomposition reactions, after the compound multi-stage purification to achieve the standard emission! It can not only purify and treat all kinds of harmful exhaust gas, but also cleanly remove all kinds of bad smell. as the picture shows:
uv光氧净化 技术特点 Characteristics of UV Photooxygen Purification Technology
1. Non-toxic without side effects. It goes beyond the traditional air purifiers such as ozone, and can continue to sterilize and remove dust in the presence of people without toxic and side effects on the human body. Can intercept and kill all kinds of bacteria in the air in a broad spectrum. Tests show that the killing rate of Legionella, Staphylococcus aureus, Bacillus subtilis, black spores and natural bacteria is more than 99.9%. Effectively remove inhalable particles, reaching 1 100,000 class cleanliness.
2. Eliminate the odor of polluted and harmful gases, the primary electrons are accelerated in the electric field, and they hit the oxygen molecules in the air. When the energy exceeds the ionization potential of the oxygen molecule, the oxygen molecule is rapidly ionized. The oxygen molecules that have lost electrons become positive oxygen ions (O2 +), and the released electrons are in turn
Combined with another neutral oxygen molecule to become a negative oxygen ion (O2-), the result is the two-stage differentiation of the oxygen ion and adsorption of the neutral oxygen molecule to form an ion group of O2 +, O2-, O2 and other oxygen aggregates, which has a very strong The oxidizing property can oxidize and decompose harmful components in polluted air into harmless products and water in a short time;
O2 + e （3.6eV） → · O + O
H2O + e （5.09eV） → · OH + HO + · OH → · OH2
Studies have shown that the oxidation potential (2.8eV) of active free radicals · OH is 35% higher than the oxidation potential (2.07eV) of highly oxidizing ozone. · The reaction speed of OH radicals and organics is several orders of magnitude higher. Moreover, the reaction of OH radicals to oxidative pollutants is non-selective and can initiate a chain reaction, which directly oxidizes most harmful substances in polluted air to carbon dioxide and water or minerals. Its mechanism of action is as follows:
H2S + · OH → HS + H2O
HS + O2 + O2 ＋+ O2－ → SO3 + H2O
NH3 · OH → NH2 + H2O
NH2 + O2 + O2 ＋+ O2 →→ NOX + H2O
CH2O + O2 ＋+ O2 → + · OH → H · COOH + H2O
