Disinfection module

Ultraviolet sterilization modules are divided into horizontal modules and vertical modules. The modules include ultraviolet lamps, quartz sleeves, and automatic mechanical cleaning systems. The module bracket design can prevent ultraviolet radiation from outside the open channel in case of accident; each module adopts an independent circuit design.

1. Underwater full cylinder disinfection module : Innovative double-bent structure effectively solves the swaying and deformation problems in rack-bending operations. The modular rack adopts the "longitudinal harp" structure design on the water surface, which uses the principle of fluid dynamics to be effective Reduce water resistance and better waterproof effect. During maintenance, hoist a single module at will without any tools, and the unique sealing process can prevent the lamp tube from being burnt out by flooding the rack.

Vertical module : It effectively improves the adaptability of the system to water flow, and can adjust the UV dose output according to the flow. The disinfection effect can still be guaranteed even if some of the lamps are damaged.

2. The world's leading ultraviolet lamp

(1) Ultraviolet lamps imported from the United States, Europe and other international advanced ultraviolet lamp manufacturers

(2) Including low-pressure lamps, low-pressure high-intensity mercury lamps, medium-pressure high-intensity lamps

(3) Excellent lamp anti-aging performance, lamp anti-aging coefficient is above 80%

(4) The system starts with a preheating process, which greatly extends the service life of the lamp

(5) Longer service life, guaranteed 12,000 hours for low-voltage lamps and 8,000 hours for medium-voltage lamps

Disinfection module

The electric control center provides the function of controlling the ultraviolet disinfection system, as well as recording the use time of the lamp and controlling the ultraviolet intensity sensor. The system uses a PLC micro-processing controller, which can adjust the intensity of the lamp tube according to the change of water volume to protect and extend the life of the lamp tube.

Power distribution system

The power distribution system can independently provide stable power and control for each module, ensuring the ease of operation of each module during maintenance. The system is equipped with grounding protection and overload protection.

Cabinet installation characteristics

The electronic ballast is installed in an independent ballast cabinet to prevent dust from entering and damage to electronic components. The cabinet is equipped with a cooling system. The indoor cabinet is made of carbon steel sprayed plastic, and the outdoor cabinet is made of 304 stainless steel.

The electronic ballast module is connected to the power wiring electrical box. The power connection box accepts the power supplied by the central control cabinet to each UV disinfection module, and transmits the detection signal of the light intensity probe in the UV disinfection module to the central control cabinet.

Advanced and stable ballast for UV lamps

(1) Provide a stable power supply and extend the life of the lamp

(2) Protect the lamp, provide short circuit/overcurrent protection, current interruption protection, and prevent surge impact

(3) Low crest factor, the crest factor is less than 1.7, effectively prolonging the lamp life

(4) It can realize the synchronous control of the operating power of the lamp tube and the water intake status to optimize energy consumption

(5) Strong voltage adaptability, Weigu electronic ballast can be used normally in the variable voltage range

(6) High power factor, the power factor is not less than 98%

(7) You can choose to configure RS485 communication interface or switch node to connect with the host computer and PLC
