UV sterilizers have a wide range of uses in the field of water treatment. Water treatment ( water treatment ) from the use of ultraviolet germicidal lamps to the method, there is direct light into the water, called submerged; ultraviolet light into the tube in the UV sterilizer cavity, known as over-current UV sterilizer. (At present, overcurrent UV sterilizers and pipeline-type UV sterilizers are mainly used) Compared with the over-flow type, the submerged structure is simple. The UV germicidal lamp is placed directly in the water. This method can be used for flowing dynamic water, but also for static water. This kind of treatment method should pay attention to the possibility that the lamp may be broken due to unexpected circumstances; if the lamp is treated for a long time, the surface of the lamp will be covered with algae and other pollutants in the water, which will seriously affect the penetration of ultraviolet rays. Ultraviolet germicidal lamps mainly use its sterilizing function in water treatment. For example, overcurrent UV sterilizers work on the principle that a certain flow rate of water generated by a water pump flows through the inner walls of the ultraviolet sterilizer and ultraviolet permeable quartz. Outside of the casing, UV light at 254 nm is used to sterilize and sterilize the water. Its characteristic is that the flow velocity of the water is very fast, generally the time that flows in the quartz outer covering does not exceed 1 second, so require the ultraviolet intensity of the germicidal lamp is very high, generally require the surface intensity to exceed 30000uw/cm2 . To produce such high UV intensity, a high-intensity, high-power ultraviolet germicidal lamp is required. If you still want to increase the disinfection effect by extending the time, then generally longer lamps are selected, longer equipment is used, or vortex rotating structures are processed on the outer wall to extend the flow of water.

Amalgam lamp, amalgam ultraviolet germicidal lamp. One type of ultraviolet germicidal lamp , most of which is a water treatment germicidal lamp , has been greatly reduced in energy consumption and maintenance due to the high power and long life of the amalgam lamp, and has become an economic alternative to suppressing and medium pressure mercury lamps. . They can save energy and generate very little heat. The UV output power is 3 to 10 times that of general low-pressure mercury lamps , and the applicable ambient temperature can be as high as 90°C.

The advantages of amalgam lamps

1, durable coating

Compared with conventional UV lamps, the unique coating of long-lived amalgam lamps guarantees that they will not suffer transmission losses of quartz glass, and therefore there will be a sustained and stable bactericidal effect over the lifetime of the lamp. The service life can reach 13,000 hours. At this time, the output power of UVC can still reach 85% of the initial UV power.

2. Great potential for cost savings

Due to the high power and long life of this lamp, the energy consumption and maintenance cycle are greatly shortened. Based on the high efficiency, long life, and low operating costs of amalgam lamps, amalgam lamps have become an economic alternative to medium voltage lamps. They save energy and produce only little heat.

3, high output

The amalgam lamp has a UV output of 3-10 times that of a general low-pressure mercury lamp. The operating temperature can be as high as 90°C and the spectrum is 254 nm.

4, wider ambient temperature

Compared with the standard germicidal lamp, it produces about 3 times longer UV output than 13,000 hours at the same length. Maintains stable high UV intensity over a wide range of ambient temperatures (4-90°C) using fewer lamps, reducing initial installation and operating costs.

According to the guidelines of the UV disinfection and sterilization technology standards, each kind of microorganism has its own specific ultraviolet killing and death dose standard, and its dose is the product of irradiation intensity and irradiation time { K ( sterilant dose ) = I ( irradiation intensity ) t ( irradiation Time ) }. From the formula, it is known that high-intensity short-time and low-intensity irradiation have the same effect for a long time. In the process of using UV sterilizer for water disinfection and sterilization, multiple-count low-intensity lamps are used in parallel or in series to illuminate and use single The short-time irradiation effect of a branch or a few high-intensity lamps may be the same, but the UV sterilizer using a low-intensity lamp increases or increases the number of lamp holders, and the number of ballasts increases, and the distribution system increases. Increased, the corresponding cost will increase, that is to say, when a large flow of water disinfection and sterilization, the use of high-power UV lamp sterilizer costs less than the use of low-power UV lamp sterilizer costs. The same power and the same number of amalgam lamps and low-pressure high-intensity ultraviolet light sterilization ultraviolet sterilizer compared, because the UV intensity of the amalgam lamp is much higher than the UV intensity of the low-pressure high-intensity ultraviolet light, so the amalgam lamp UV sterilizer Better disinfection. Ultraviolet sterilizer manufacturers Shijiazhuang Ling Zhuo Environmental Protection Equipment Co., Ltd. of amalgam lamps UV sterilizer has already achieved mass production.
