Shandong medium voltage ultraviolet sterilizer manufacturer

Description :

　　The Shandong medium voltage ultraviolet sterilizer manufacturer is a high-tech product developed by Guanyu Company based on years of experience in ultraviolet disinfection treatment, combined with multiple experiences in large and medium-sized municipal water disinfection treatment and swimming pool water disinfection treatment. It is jointly developed by professors, design engineers, on-site operators and other parties in various disciplines.

　　Product advantages

　　Wide range of sterilization and disinfection: The output wavelength range of the medium voltage ultraviolet lamp tube in the medium voltage ultraviolet sterilization system is relatively wide, between 230nm and 370nm, which can kill all bacteria and viruses and permanently inactivate chlorine resistant microbial tissues, such as Legionella pneumophila, Escherichia coli, Pseudomonas aeruginosa, Cryptosporidium, Amoeba, and bacteria.

　　Strong sterilization effect: While damaging the DNA structure of microorganisms, it also decomposes them into small fragments. It is precisely because of this medium pressure ultraviolet sterilization characteristic that Shandong medium pressure ultraviolet sterilizer manufacturers can avoid the occurrence of photoreactivity and dark repair of DNA in microorganisms. Therefore, it can have a long-lasting inactivation effect on microorganisms without revival reaction or microbial rebound phenomenon.

　　No secondary pollution: No toxic or harmful by-products are produced during the disinfection process, the composition and properties of the disinfected water are not changed, and there is no secondary pollution to the water body and surrounding environment.

　　Decompose residual chlorine and degraded chemical chlorine in water: When using a medium pressure ultraviolet sterilizer for water disinfection, it can reduce the chlorine content in the water, reduce disinfection by-products, and make the water environment healthier. Medium pressure ultraviolet radiation has the ability to degrade chlorinated compounds, including monochloramine, dichloroamine, trichloroamine, etc., effectively preventing the production of carcinogenic substance trihalomethanes and eliminating the impact of chlorinated compounds on the human body.

　　Low cost of use: Due to the improvement of technology, medium voltage ultraviolet disinfection technology not only has the highest disinfection efficiency among all disinfection methods, but also has simple operation and maintenance, low operating costs, and can reach 4 cents per ton of water at a processing capacity of one thousand tons.

　　Easy installation and operation: The medium voltage ultraviolet disinfection system is designed with modularity and is easy to install. Shandong medium voltage ultraviolet disinfection equipment manufacturer is suitable for complex installation site conditions without damaging the equipment, pipelines, and building structures on site. The design of a closed system can be directly installed onto pipelines, with options for horizontal and vertical installation.

　　Small footprint and no noise: The medium pressure ultraviolet disinfection equipment that processes 10000 tons of clean water per day only requires 6 square meters of operating space.

　　Continuous high water disinfection: Currently, ultraviolet disinfection technology has reached a daily processing capacity of 1.5 million tons of water in practical applications. If needed, it can be even larger, which is not easy to achieve with chlorine addition, dechlorination, and ozone disinfection methods.

　　Wide application fields: Medium pressure ultraviolet disinfection equipment can be applied in the catering industry, swimming pools, wastewater, wastewater reuse, and offshore oil and gas, meeting the disinfection requirements of various industries.

　　Characteristics of Guanyu medium voltage ultraviolet sterilizer:

　　Medium voltage ultraviolet lamp: Adopting high-quality American imported LightSources brand ultraviolet lamp with high power and reduced lamp configuration, it can handle high flow water bodies. Compared with low-voltage ultraviolet lamps, ultraviolet light has a higher intensity and a wider wavelength of radiation.

　　Temperature probe: Immediately detect the temperature of the water to ensure that the equipment operates within the working temperature range of 0-45 degrees.

　　UV intensity probe: The intensity monitor used in the medium voltage UV sterilizer only responds to specific UV wavelengths that have sterilization effects. It can be connected to computers and PLCs, saving power consumption for the operation of the system.

　　Quartz sleeve: In order to better protect the ultraviolet lamp tube, there is a quartz sleeve outside each ultraviolet lamp tube. Therefore, the quality of quartz tubing largely determines the sterilization effect of medium voltage ultraviolet sterilizers, and high-quality quartz tubing can ensure that the penetration rate of ultraviolet rays reaches over 90%.

　　Daily cleaning: Due to water quality and exposure to ultraviolet light, the surface of the quartz sleeve will crystallize after a period of use. The thickness of the crystals will reach a certain level, which will affect the penetration ratio of ultraviolet light. Therefore, the quartz sleeve needs to be cleaned regularly. The medium voltage ultraviolet sterilizer is equipped with an automatic cleaning system, which can automatically clean the quartz sleeve at regular intervals based on the readings of the ultraviolet intensity detector. During the cleaning process, the system operates normally without the need for water supply or manual intervention, greatly reducing the workload of on-site personnel.
