Description

A UVC LED purification device for air or water

technical field

The invention relates to the field of photochemotherapy by LED deep ultraviolet light irradiation, and more specifically relates to a UVC LED air or water purification device.

Background technique

Both air and water are the source of life, which nourishes all things and feeds life. Contemporary China, which is in a period of social transformation, is facing numerous environmental pollution problems, among which air and water pollution are particularly prominent. The serious deterioration of air and water ecology makes people have to face this serious problem. And it is expected that the natural environment will be difficult to improve for a long time.

All kinds of bacteria, microorganisms, and volatile gases in the air or water, including various toxic and harmful gases, such as formaldehyde, benzene, dioxin, etc., their molecular diameters are all at the nanometer level, and the particle diameter of the smoke type is about 0.1um , from the point of view of purification treatment, it is very important to eliminate these types of substances. For PM2.5, large diameter particles such as dust and falling ash are easy to intercept, and only a simple ordinary filter can be used to solve the problem. Besides drinking tap water, from January to April 2014 alone, there were more than ten incidents of tap water problems that were exposed nationwide. In drinking tap water, coliform bacteria are a collective term: including Escherichia coli, Three highly pathogenic and highly contagious bacteria such as fecal coliform bacteria and heat-resistant coliform bacteria. The more chlorine is added, the safer it is. The combination of chlorine and organic matter in water can produce disinfection by-products, and most of the disinfection by-products are carcinogenic and mutagenic, harmful to the human body, and the impact is a chronic one. The process is not easy to detect. At present, traditional purifiers generally adopt multi-layer filter layer settings to intercept to achieve disinfection, but with this treatment process, the effect is not great, and it is impossible to eliminate harmful substances, which will cause secondary and repetitive pollution.

The UV light produced by the traditional high-pressure mercury lamp ultraviolet sterilization equipment looks very bright, high in heat, large in size, high in power consumption, and wide in spectrum. The ultraviolet spectrum that is really effective in sterilization and disinfection only accounts for a part of its energy. , A considerable part of the heat is generated in the visible light segment. Although the total output power of traditional UV mercury lamps or UV mercury lamps is large, the output of deep ultraviolet light per unit area is very weak, only a few hundredths of 260nm to 280nm ultraviolet light-emitting diodes. Because mercury gas is produced during high-pressure mercury work, it is not friendly to the environment, so it will cause secondary pollution. The effect produced cannot reach the effect of disinfection and sterilization.
