Ultraviolet sterilizing device

Abstract

The invention discloses an ultraviolet sterilizing device. The ultraviolet sterilizing device comprises a shell, a water inlet, transverse separator plates, a water outlet, a movable sealing plate, a sealing strip and an ultraviolet lamp, wherein the shell is a flat box with a rectangular longitudinal section; the transverse baffle plates and the ultraviolet lamp are mounted in the flat box body; a flow channel for a transverse fluid is partitioned by the parallel transverse separator plates; the adjacent transverse separator plates are crossed on two sides of the flat box body to form a channel; holes are uniformly formed in the transverse separator plates and a vertical-line hole is formed after mounting; a sealing ring sleeves the hole and is used for enabling the ultraviolet lamp to insert; a lamp holder electrically connected with the ultraviolet lamp is arranged at top end of the flat box body; a plane of the flat box body adopts the movable sealing plate and the box body is sealed by the sealing strip.

Description

1. Technical field [0001] The invention relates to an ultraviolet disinfection device, in particular to an ultraviolet disinfection device for fluid (including water body and air) which is convenient for cleaning and mobile. 2. Background technology [0002] With the development of industry and social progress, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Due to the more complex components of wastewater, some of which are toxic, wastewater treatment is more difficult. Difficulties are also more important. For some typical high-concentration organic wastewater, such as coking wastewater, pharmaceutical wastewater, textile / printing and dyeing wastewater, petroleum / chemical wastewater, landfill leachate, etc., the effluent COD concentration of the main production sections is generally above 3000-5000mg / L, and some The effluent water in the pr...

Problems solved by technology

[0008] As can be seen above, TiO 2 Photocatalyst is the main unit of photocatalytic oxidation on the surface of three-dimensional carbon foam, carbon material and foam honeycomb ceramic for air or water treatment (especially water treatment). The photocatalytic material is effective (reflective and refraction performance is not good), and the action area (thickness) is not large. In fact, thin foam cellular ceramics cannot be prepared and put into practical use, which affects the intensity and efficiency of photocatalysis, which also fixes the cost and processing. The reason for the high cost

[0009] Although the photocatalysis and new photocatalytic additives loaded with titanium dioxide have the activity of catalytically decomposing water molecules into hydrogen and oxygen, they cannot be widely used in water treatment. The main reason is that the effective catalytic area is too small and there is no The ultraviolet light area cannot carry out catalytic reaction, and the honeycomb ceramics can only flow the water on the surface that it touches, and cannot make all the water body carry out catalytic reaction

[0010] But the existing ultraviolet disinfection device is not easy to clean and move, and the efficiency of ultraviolet disinfection to fluid (including water body and air) will be greatly reduced, especially when used for water treatment in aquaculture, the amount of water required for disinfection treatment is large, and Subtle impurities or plankton in the water will have a great impact on the light transparency of the UV disinfection device, especially when it is used for pure UV light treatment
