Large-scale domestic sewage treatment UVC U shape UV lamp
The role of ultraviolet light, inventory of four magic methods
UV lamps are not very familiar to many friends. Although it has a lamp in its name, it is not used for lighting, but is used in many other aspects, such as medicine, food and drinking water. In addition, it can also be used for other purposes. Regarding its specific functions, the editor will introduce them one by one.
1. Ultraviolet lamps are used in medical treatment
If human skin is exposed to ultraviolet lamps, it may cause certain damage to the skin, but not all ultraviolet lamps are like this. Some wavelengths of ultraviolet lamps will not only cause harm to human skin, but also if used for medical treatment. It can effectively relieve the pain of the patient. For example, in the treatment of vitiligo, after applying the medicine, receiving appropriate ultraviolet light irradiation can achieve the effect of treating the disease by producing melanin.
2. Ultraviolet lamp is used for detection
In terms of detection, UV lamps have played a lot of roles. The anti-counterfeiting mark drawn by ultraviolet fluorescent material will not show any pattern under normal lighting conditions, but when irradiated with ultraviolet light, it can display the corresponding pattern and information, which is very convenient and quick to detect.
3. Ultraviolet lamps are used for sterilization
Ultraviolet lamp is made by the principle of ultraviolet sterilization, so it can also have a great effect in disinfection and sterilization. Therefore, in daily life, many families buy ultraviolet lamps to sterilize their homes, and public places such as hospitals, schools, nursing homes and other public places will also use ultraviolet lamps for sterilization to ensure indoor sanitary conditions.
4. UV lamp is used for curing
The UV lamp has some curing effect, which can quickly solidify the liquid into a solid, which has achieved the effect of fixing and coloring. Like in daily life, our common UV glue and UV ink are made of this principle. And some electronic products that are often played or commonly used by modern people also use this function of ultraviolet lamps in many aspects.
Ultraviolet lamps are widely used in daily life, whether it is medical treatment of diseases, or detection and anti-counterfeiting in life, so that the disinfection and sterilization of living spaces can be achieved by ultraviolet lamps. The emergence of ultraviolet lamps is a manifestation of social progress, which provides a lot of convenience for production and life." "Whether the effect of ultraviolet germicidal lamps is good or not is mainly affected by the following factors:
One: Glass materials, there are high boron glass, quartz glass, synthetic quartz glass.
High boron glass: also known as soft glass, it only needs three or four hundred degrees of fire temperature to be softened for processing, only 254nm band (no ozone) is generated, and no ozone is generated.
Quartz glass: It needs a fire of 1800 degrees to be soft and processed. It cools and hardens immediately after the fire leaves. It is very difficult to make. It can be made with or without ozone. The ultraviolet transmittance, hydroxyl content, purity and impurity content of quartz glass, These data are very good. The more ultraviolet rays that pass through, the better the sterilization effect. There are many manufacturers of quartz glass on the market, and the quality is uneven. The price per kilogram of glass varies greatly, so the price of the lamp is also different. It is very big. Although it is said that the user can't see it, it is good to know that the lamp is on. However, it is completely unknown whether the ultraviolet sterilization effect is still there. It is better to know more about the strength of the manufacturer before purchasing. Self-control to evaluate.
Synthetic quartz glass: Not much to say about this, glass is very expensive, very expensive, very expensive. Of course, it goes without saying that the light tube produced has a very good transmittance and very little attenuation, and the effect is naturally good. The production cost is too high. Generally, if it is necessary for scientific research and experiments, we will find us to customize the lamp.
In addition, let's talk about the attenuation of quartz glass, what is the principle? Ultraviolet rays irradiate the wall of the glass tube for a long time. The glass is a single crystal of silicon dioxide. The long-term irradiation will change, and the holes that can transmit ultraviolet rays will be blocked. Therefore, the ultraviolet rays of the lamp tubes are attenuated. Generally, lamp manufacturers will mark the lamp tube. How long is the lifespan? Although the lamp is still on when the time is up, the ultraviolet rays are already very small, and the effect of the newly produced lamp is not as good. That's why.
Two: The production process is good or not.
To make a quartz ultraviolet germicidal lamp, there are still many processes. There are dozens of processes, large and small, but only the main processes are briefly mentioned.
Clamping process: Whether this process is done well or not directly affects whether the lamp tube will leak or slowly leak. The expansion coefficients of molybdenum sheet and quartz glass are close, so molybdenum sheet and quartz glass are used for sealing. After the phase is clamped, the sealing is completed. Whether the fire is well adjusted will affect whether the glass is soft enough to burn. very critical.
Exhaust process: After the lamp tube is sealed, it needs to be vacuumed to remove the air, impurities, and impurities in the wick. It needs to be baked at high temperature while pumping. Baking time, power-on time of each gear, etc. Whether the vacuum degree is high or not will affect the life of the lamp tube, and the exhaust process is a very important process. After the exhaust is completed, the capillary is basically completed. After that, the lamp tube is matured, and the lamp holder is assembled." "Application range:
1. Large-scale domestic sewage treatment, reclaimed water reuse, disinfection and sterilization of industrial sewage treatment, drinking water, residential water supply, pure water, high-purity water;
2. Seawater treatment, central air conditioning, large ventilation pipes, air disinfection and sterilization.
3. Disinfection and sterilization of various water bodies such as pure water, domestic water, ionized water, and medical water;
4. Water treatment supporting equipment; Photocatalytic photocatalyst degrades waste water, and is used in waste water treatment.
5. Kitchen equipment, cutting boards and tableware disinfection cabinets, and oil fume pipes to deodorize."

Application of Photolysis Ultraviolet Lamp |
1. Remove peculiar smell and purify industrial waste gas |
Using high-energy UV light with a wavelength of 185 nanometers, it decomposes oxygen molecules in the air to generate ozone. Ozone has a strong oxidizing effect on organic matter, degrading and converting odorous gas substances into low-molecular-weight compounds. Water and carbon dioxide provide immediate removal of malodorous gases and other irritating odors |
2. Remove odor and purify industrial waste gas |
Food Processing Plant, Meat Processing Plant, Slaughterhouse, Poultry Feed Factory, Paper Mill, Sewage Treatment Plant, Waste Transfer Station, Manure Treatment, Oil Refinery, Rubber Factory, Leather Factory, Printing Factory, Chemical Factory, Chinese and Western Medicine Factory, Metal Deodorization and purification treatment of organic and inorganic malodorous gases in foundries, plastic recycling plants, spraying solvent lamps. |
3. Kitchen fume purification |
Kitchen fume purification Ultraviolet lamps that generate ozone can be used in oil fume purification equipment. Ultraviolet light cools the oil molecules to generate trace powder, carbon dioxide and water. The organic matter in the oil fume is photolyzed and oxidized, and the odor in the flue is also eliminated. In addition, there is no grease residue in the fume exhaust pipe, which greatly eliminates the hidden danger of fire. |
