In order to make the metal workpiece possess the special mechanical, physical and chemical properties required, besides selecting suitable materials and processes, the quenching heat treatment of metal is an indispensable process. In the quenching heat treatment process, the high temperature workpiece enters the medium cooling process and produces huge quenching heat treatment waste gas and a large number of quenching heat treatment produced by quenching heat treatment. Oil fume exhaust smoke in the workshop, full of greasy and stimulating odor, not only brings huge pollution to the air environment, but also the exhaust gas of nitric oxide, nitrogen dioxide, sulfur dioxide, water, and a small amount of carbon particles endanger human health.
Working principle:
This equipment is the perfect combination of plasma decomposition exhaust gas purifier and UV light deodorization exhaust gas purifier. It combines the advantages of plasma exhaust gas purifier and ultraviolet photocatalyst deodorization exhaust gas purifier. It combines plasma decomposition technology with UV ultraviolet photolysis technology to efficiently and synergistically purify the exhaust gas and odor.
(1) After the exhaust gas and odor gas enter the integrated equipment, they are irradiated by ultraviolet light wave with high efficiency and high efficiency, instantaneously produce photolysis reaction, open chemical bonds of exhaust gas and odor pollutant molecules, destroy their molecular structure and nucleic acid; use high-energy ultraviolet light wave to decompose oxygen molecules in the air to produce free oxygen, i.e. reactive oxygen, because of the positive and negative electrons carried by free oxygen. Because of the imbalance, it is necessary to combine with oxygen molecules to produce ozone, so that the free pollutant molecules can be combined with ozone oxidation to form harmless or harmless compounds with small molecules.
(2) Exhaust gas and odorous gas pass through the plasma electric field, and in the nanosecond time range, plasma bombards pollutant molecules such as exhaust gas and odor violently, producing fission decomposition reaction, producing various active free radicals, high energy electrons, high energy ions and so on with high concentration, high intensity and high energy. At the same time, a large number of mixed gases such as ozone, atomic oxygen and ecological oxygen are produced to carry out a series of reactions. A series of complex splitting and redox reactions.
(3) UV-UV photolysis and plasma decomposition can produce a series of photolysis and decomposition reactions so efficiently and synergistically that the standard discharge can be achieved after multi-stage purification. It can not only purify and treat all kinds of harmful waste gases safely and efficiently, but also remove all kinds of odors efficiently and cleanly.
Ultraviolet photolysis and ozone catalytic reduction zone:
1. Using special high-energy and high-ozone UV ultraviolet ray beam to irradiate odorous gases and crack odorous gases such as ammonia, trimethylamine, hydrogen sulfide, methyl thiol, methyl thioether, dimethyl disulfide, carbon disulfide and styrene, sulfide H2S, VOC, benzene, toluene and xylene, the free pollutant molecules can be combined with ozonation to form harmless or low molecular weight. Harmful compounds, such as CO 2, H 2, etc.
2. Using high energy and high ozone UV ultraviolet light beam to decompose oxygen molecules in the air to produce free oxygen, i.e. reactive oxygen species, because of the positive and negative electron imbalance carried by free oxygen, it needs to combine with oxygen molecules to produce ozone. UV + O 2 O - +O* (reactive oxygen species) O + O 2 O 3 (ozone), it is well known that ozone has a strong oxidative effect on organic matter, and has a strong scavenging effect on odorous gases and other irritating odors.
3. After the odor gas is input into the purification equipment by exhaust equipment, the purification equipment uses high-energy UV ultraviolet ray beam and ozone to decompose and oxidize the odor gas synergistically, so that the odor gas can be degraded into low molecular compound, water and carbon dioxide, and then discharged outdoors through the exhaust duct.
4. Using high-energy UV beam to crack the molecular bonds of bacteria in odor gas, destroy bacterial nucleic acid (DNA), and then oxidize through ozone to completely achieve the purpose of deodorizing and killing bacteria.
