Now people's living environment and quality of life have become better and better, and the development trend of people's machine and equipment manufacturing industry has become more and more mature. The appearance of this good mature commodity can make greater improvements in our daily life.
Photocatalytic reaction technology in wastewater treatment and waste gas treatment is the mature processing technology. The key to the effectiveness of the processing technology lies in the ultraviolet compressive strength, the catalytic reaction ability of metal catalysts and the catalytic reaction time. From Photocatalyst formaldehyde removal air purifier to catalytic oxidation waste gas treatment equipment, many very unscientific designs can be found, such as residence time of waste gas in treatment equipment; catalyst area; catalyst purity and nanometer diameter of titanium dioxide; catalyst curing structure; setting of ultraviolet lamp (quantity, distance). All of them directly determine and influence the photocatalytic oxidation ability.
Machinery and equipment suitable for lower concentration of waste gas treatment, indoor air treatment, processing technology consist of "water spray + photocatalysis", such as: hospital, laboratory air purification, municipal sewage treatment plant deodorization, sewage pump station deodorization, industrial workshop deodorization, drying process waste gas, waste gas from refuse transfer station. The equipment is divided into ozone and ozone-free.
1. The product irradiates odorous gases by special high-energy and high-ozone ultraviolet rays, changing the molecular chain structure of organic or inorganic polymers such as ammonia, trimethylamine, hydrogen sulfide, methyl sulfide, methyl sulfide, dimethyl disulfide, carbon disulfide and styrene, sulfide H2S, VOC, benzene, toluene and xylene. Molecular chains of odorous compounds are degraded into low molecular compounds, such as CO 2 and H 2, under the irradiation of high-energy ultraviolet light.
Secondly, using high energy and high ozone ultraviolet ray beam to decompose oxygen molecules in the air to produce free oxygen, i.e. reactive oxygen species. Ozone is produced by the combination of oxygen molecules and oxygen molecules because of the unbalance of positive and negative electrons carried by free oxygen. 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 an immediate effect on the elimination of odorous gases and other irritating odors.
3. After the odor vapor is typed into the oil fume purifier by using exhaust system equipment, the operation of the oil fume purifier shocks UV ultraviolet light and reactive oxygen species to carry out cooperative dissolution and redox reactions on the odor vapor, so that the odor vapor substances can be degraded into low molecular compounds, water and carbon dioxide, and then discharged through the exhaust duct. Out of doors.
4. Deodorizing and killing bacteria can be achieved thoroughly by using high-energy UV beam to crack the molecular bonds of bacteria in odor gas, destroy bacterial nucleic acid (DNA), and then oxidize by ozone.
