Description

technical field [0001] The invention relates to the technical field of ultraviolet sterilization, in particular to a novel integrated control system for a drinking water sterilizer. Background technique [0002] Ultraviolet sterilization is widely used in the field of water treatment sterilization and disinfection. The principle is that ultraviolet rays of appropriate wavelengths can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, resulting in growth cells and regeneration. Sex cells die or cannot reproduce offspring to achieve the effect of sterilization. It is UVC ultraviolet rays that really have a bactericidal effect. C-band ultraviolet rays (UVC) are easily absorbed by the DNA of organisms, especially ultraviolet rays around 253.7nm are the best. The principle of ultraviolet sterilization and disinfection technology is based on modern epidemiology, medicine and photodynamics. It uses specially des...

Problems solved by technology

This ultraviolet sterilizer for drinking water saves energy and prolongs the service life of the lamp tube, but only relying on the water flow to control the working state of the lamp tube through the switch mode, the actual effect it can achieve is limited

[0004] The patent document whose publication number is CN201379814Y discloses an automatic control type ultraviolet sterilizer, which can automatically light up and adapt to the number of ultraviolet lamps according to the amount of disinfection liquid. Flow tank and programmable controller, according to the liquid flow signal received by the programmable controller to judge the number of open ultraviolet lamps and automatically open the operation, saving electric energy and improving the use efficiency of ultraviolet lamps, but this ultraviolet disinfection The solution is only to control the number of UV lamps to be turned on according to the water flow, without any monitoring of the operating status of the lamps themselves, and the actual effect achieved is very limited

After the lamp tube is turned off, it is easy to cause a blind area of ​​sterilization and disinfection, so that some bacteria cannot be effectively killed and the sterilization effect is reduced.

[0005] The systems disclosed in the above two patent documents have limited functions, and cannot monitor the operating status of each ultraviolet lamp in real time, and cannot obtain the UV intensity information and current water flow after the ultraviolet light emitted by the ultraviolet lamp in the current system penetrates the quartz sleeve in real time Whether the bactericidal dose meets the requirements of use under the conditions, and at the same time, the UV output of the ultraviolet lamp cannot be accurately adjusted through information such as the current water quality transmittance, UV intensity, and water temperature, so as to meet the UV dose requirements for sterilization and disinfection

[0006] The patent document whose publication number is CN105253949A discloses a water source ultraviolet sterilizer control system and its control method, which adjusts the ultraviolet intensity through the monitoring information of the water temperature through the control method, and solves the existing ultraviolet sterilizing problems by monitoring the ultraviolet lamp itself. The problem that the controller cannot obtain the status information of the light source in time

However, the function of this system is also limited, and it does not involve how to ensure sufficient UV dose to meet the sterilization requirements for different flow rates and water quality transmittances.
