Ultraviolet lamp tube capable of efficiently generating ozone

Abstract

The invention provides an ultraviolet lamp tube capable of efficiently decomposing air to generate ozone, a main component is called as a base body, the base body comprises a light-emitting unit for generating ultraviolet rays and a lamp tube shell which is arranged on the outer side of the light-emitting unit and has a catalytic effect, and a catalytic part used for increasing ozone generation is arranged on the base body in a matched mode. The invention aims to improve the ozone generation efficiency, and the generated ozone is diffused into the space to disinfect the surface of an object in the environment instead of locally catalyzing the ozone to generate a chemical reaction, so that the ozone consumption is accelerated. The ultraviolet light transmission efficiency of the lamp tube can be reduced when the catalyst is plated on the surface of the whole lamp tube, the ozone yield is reduced, and the ultraviolet light transmission efficiency cannot be affected when the catalyst is plated on the protruding edges of the grids.

Description

technical field [0001] The present disclosure is in the technical field of ultraviolet light tubes, and in particular relates to a high-efficiency ultraviolet light tube for decomposing air to generate ozone. It mainly produces ozone with high efficiency at the lamp tube, and distributes the generated high-concentration ozone into the space for disinfection and sterilization. Background technique [0002] Ozone, molecular formula O 3 , is oxygen (O 2 ) allotropes. At room temperature, ozone is light blue, with a fishy smell. Ozone is composed of an oxygen molecule carrying an oxygen atom [O]. It is a temporary state, unstable and highly oxidizing. Therefore, ozone is easily decomposed. The half-life of ozone in the unstable reference state is 22 to 25 minutes, the decay rate in one hour is 61%, and the half-life in 1% ozone aqueous solution is 16 minutes, and the higher the temperature, the greater the humidity, The shorter the half-life. According to the summary and c...

Problems solved by technology

Under the action of a high-voltage corona electric field, the by-product is the decomposition of nitrogen in the air to produce harmful gases; if pure oxygen is used as the gas source, the cost of use will be significantly increased

[0006] 2. Complex structure and low efficiency

Although the existing photolysis air scheme uses ultraviolet lamps, under the premise of using air as the gas source, the effective airway length and contact area are improved by increasing the structural complexity, while the ozone itself is unstable and will Self-decomposition in the road, the comprehensive effect is high cost, low efficiency, and the structure is too complicated
