Led UV sterilization compared with traditional sterilization

Technology sharing · 2017-11-15 22:52:17

Led ultraviolet disinfection has incomparable advantages over traditional chlorine disinfection. Chlorine disinfection will form a chlorine compound in water, which is a carcinogen. Moreover, when chlorine concentration is high, there will be a smell. If you drink raw water, you will obviously smell this strange smell.

Now there is another way to disinfect water: ozone. Ozone can also kill bacteria, but when its concentration is high, the decomposition time of ozone will be prolonged. It is likely to be transported to residential houses through close pipelines. Ozone water can beautify and wash vegetables, but it can't be drunk, and its taste is bad. If the concentration is reduced, the bactericidal ability will be weakened. In addition, ozone disinfection should also prevent leakage.

Due to the wide use of ultraviolet disinfection and sterilization, including hospitals, schools, nurseries, cinemas, families and so on, because it can purify the air, eliminate the musty smell, and also produce a certain amount of negative oxygen ions, the air in the room disinfected by ultraviolet rays is particularly fresh. In public places, ultraviolet disinfection can also avoid the possibility of some pathogens spreading through the air or through the surface of objects.

With the change of the market and the demand of the industry, especially in the food processing and catering hygiene industry, the ordinary ultraviolet glass lamp tube is often burst due to the long exposure time and the glass lamp is easy to break, which makes the glass impurity dangerous food processing process. At the same time, long-time ultraviolet air irradiation makes the power consumption of production enterprises, public places and restaurants This is contrary to the resource-saving society advocated by the government. Traditional ultraviolet lamps emit ultraviolet light mainly by excited ionization of heavy metal vapor (the most commonly used is highly toxic mercury). The main peak wavelength of mercury lamp is 253.7nm, but it is not consistent with the electromagnetic wave absorption peak of DNA (265nm), so it is not the best disinfection wavelength. Compared with LED, which belongs to semiconductor products, the volume of traditional UV lamp is very large and needs high voltage lighting. In addition, although the total output power of the traditional mercury lamp is large, the output light intensity of the position area is very weak, which is only one hundredth of the LED UV. Moreover, it has the disadvantages of inconvenient use and maintenance, short service life, high energy consumption, containing toxic mercury and so on. UVLED germicidal lamp can solve the above problems.
