Hebei medium voltage ultraviolet sterilizer

Description :

　　The Hebei medium voltage ultraviolet sterilizer has the characteristics of no dead corners, good light irradiation conditions, low energy consumption, flexible and convenient equipment installation and disassembly, and no secondary pollution. Compared with chlorine gas sterilization, the ultraviolet sterilizer has the advantages of no need to add chemical agents, no secondary pollution, no mixing equipment, greatly reducing equipment operating costs. If it is drinking water, the ultraviolet sterilizer is safe and will not have adverse effects on the human body due to excessive agents. Compared to ozone sterilizers, ultraviolet sterilizers have the advantages of low energy consumption, no large mixers, and no fishy smell. Hebei medium pressure ultraviolet sterilizers not only have good sensory effects, but also reduce operating costs.

　　The structural form of UV sterilizers: UV sterilizers are divided into closed and open types according to the different water flow boundaries.

　　Closed system

　　The enclosed UV sterilizer belongs to the pressure type, which uses a metal cylinder and an ultraviolet lamp with a quartz sleeve to seal the disinfected water.

　　The cylinder body is commonly made of stainless steel or aluminum alloy, and the inner wall is often polished to improve the reflection ability of ultraviolet rays and enhance radiation intensity. The number of ultraviolet lamps can also be adjusted according to the amount of treated water. Some disinfectors are equipped with spiral blades on the inner wall of the cylinder to change the movement of water flow and avoid stagnant water and pipe blockage. The turbulence generated and the sharp edges of the blades will crush suspended solids, exposing attached microorganisms completely to ultraviolet radiation and improving disinfection efficiency.

　　Closed type is also divided into open type and submerged type. Open type disinfectors are suitable for medium and large water treatment and are commonly used in sewage treatment plants. Closed sterilizers are generally suitable for handling medium to small water volumes or situations where pressure is necessary and the sterilizer cannot be used in open channels.

　　UV lamps with sealed quartz sleeves in various systems can be arranged perpendicular or parallel to the direction of water flow. Parallel systems have low hydraulic losses and uniform water flow patterns, while Hebei medium pressure ultraviolet disinfectors can disrupt water flow and improve disinfection efficiency.

　　Open system

　　The water disinfected in the open UV sterilizer flows through the UV sterilizer under the action of gravity and inactivates microorganisms in the water. Open systems can be divided into two types: submerged and surface systems.

　　Immersion method, also known as underwater irradiation method. Place the UV lamp with a concentric quartz sleeve in water, and let the water flow around the quartz sleeve. When the lamp tube (group) needs to be replaced, use a lifting device to lift it to the working surface for operation. This method is relatively complex in construction, but it has a high utilization rate of ultraviolet radiation energy, good performance, and is easy to maintain.

　　The water surface method, also known as the water surface irradiation method, involves placing ultraviolet lamps on the water surface and using parallel ultraviolet light generated by parallel electronic tubes to disinfect the water. This method is simpler than immersion, but it wastes more energy and has poor sterilization effect, and is rarely used in actual production.

　　Characteristics of medium voltage ultraviolet sterilizer:

　　Medium voltage ultraviolet lamp: Adopting high-quality American imported Lightsources brand ultraviolet lamp with high power and reduced lamp configuration, Hebei medium voltage ultraviolet sterilizer can treat 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.
