Detailed Instructions for Cleaning Open-Channel UV Disinfectors

Currently, all frame-type—or open-channel—UV disinfectors on the market are pneumatic: an air compressor drives a cylinder to push and pull the cleaner.

 

The open-channel UV disinfection module is installed in an open-type UV disinfection channel. For ease of maintenance, both the power distribution cabinet and the control cabinet are mounted above the channel. The UV lamp arrays are arranged parallel to the direction of water flow within the open channel! The open-channel UV disinfection equipment should include: a set of UV lamp modules, module brackets, a power distribution center, a system control center, as well as water level sensors and control outputs.

 

The modular structure of the open-channel UV disinfection unit is designed based on fluid dynamics principles and features a low-resistance design that minimizes the impact of water flow on the modules. This effectively prevents the resistance of flowing water from affecting the lamp tubes and the cleaning system, thereby providing better protection for the lamps. For lamp tube cleaning, an air-driven rodless cylinder is used to perform automatic cleaning. A single cleaning head completes the entire cleaning process of the casing in one go, leaving no dead corners behind. After cleaning is finished, the cleaning head stops at the very end of the casing—where there is no UV light output—thus ensuring that it does not obstruct the UV disinfection process and maximizing its bactericidal effectiveness.

 

 

During the automatic cleaning process, the system functions normally, and the disinfection effect remains unaffected. (The new cleaning system effectively addresses the instability in cleaning and damage to lamps—issues that have long plagued existing products on the market due to their structural design.)

 

This UV disinfection system can automatically shut off the lamps above the water level in response to changes in water level, preventing the lamps from remaining lit for extended periods without water and thus avoiding unnecessary damage. Additionally, at low water levels, the system can achieve the same disinfection effect without needing to adjust the power output of individual lamps. This not only conserves energy but also ensures that the irradiation energy reaches the required dosage. As the water level rises, the corresponding lamps will automatically open.

 

Main features of open-channel UV disinfection systems:

1 , the entire module is selected. 304/316 Made of stainless steel.

2 Equipped with a collaborative microcomputer touch screen, it enables fully automatic remote cleaning operations.

3 It displays the UV radiation dose in real time and can turn on or off unnecessary UV lamps according to the actual water flow rate.

4 — Use ultra-long-life UV sterilization lamps (from Germany’s Heraeus or the U.S.) LIGHT SOURCE ) and high-transmittance quartz sleeves ( UVT >75% ).

5 The low-water-resistance module structure has lower water resistance than the traditional module structure, and the water level changes little before and after disinfection.

6 , waterproof rating meets the requirements IP68 Grade specifications, suitable for applications with stringent requirements.
