Water purifier

Abstract

The invention discloses a water purifier which comprises a cylinder body, a cylinder cover and a plurality of reactors. The cylinder body is a water reservoir with an opening in the upper end and a cavity inside; the cylinder cover is arranged on the top of the cylinder body in a covering mode; the upper ends of the reactors are fixed to the cylinder cover, and the lower ends of the reactors are inserted into the inner cavity of the cylinder block; the reactors comprise ultraviolet lamps, first quartz tubes, second quartz tubes and water inlet pipes; the first quartz tubes are hollow transparent quartz tubes with open upper ends and sealed bottoms, the lower ends of the tube bodies are vertically inserted into the inner cavity of the cylinder body, and the upper ends of the tube bodies are fixed to the cylinder cover; the ultraviolet lamps are inserted into the inner cavities of the first quartz tubes; the second quartz tubes are transparent quartz tubes with openings in the upper ends and lower ends and cavities in the middle parts; the second quartz tubes are arranged on the outer sides of the first quartz tubes in a sleeving mode; the water inlet pipes are further arranged on the cylinder cover and communicated with the upper ends of the second quartz tubes. The water purifier can decompose organic pollutants in water and kill viruses and bacteria efficiently and rapidly.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purifier. Background technique [0002] Ultraviolet lamps with two bands of 185nm and 253.7nm, commonly known as ozone lamps. Among them, 185nm ultraviolet rays can decompose organic pollutants in water; 253.7nm ultraviolet rays can inactivate microorganisms, that is, disinfection. Putting the ozone ultraviolet lamp in the water can achieve the effect of removing pollutants and disinfection in the water at the same time. However, the penetration rate of 185nm ultraviolet rays in water is very low, and it can only affect the water body around 1cm around the lamp. The penetration rate of 253.7nm ultraviolet rays in water is very high, and the pure water can reach more than 95% (1cm optical path). How to combine the two reasonably is an important optimization problem. [0003] It is a chemical process that 185nm ultraviolet rays can decompose organic pollutant...

Problems solved by technology

[0003] It is a chemical process that 185nm ultraviolet rays can decompose organic pollutants in water. The process of photon-induced decomposition of organic molecules is completed in a very short time. The movement of reactants and products is a law-speed process of the reaction process; Very low transmittance
