Fluid sterilization disinfection purifying device

Abstract

A fluid sterilization and purification device includes a box (1) with an inlet and an outlet (6, 7), a fan (2) installed in the box and a UVC UV lamp (3); the top plate of the box is a hinged cover plate (4); an inner cavity between the inlet and the outlet of the box is separated with a plurality of plastic partition plates (5); an air hole (7) is arranged on one side of each plastic partition plate; air holes of adjacent plastic partition plates are staggered; both sides and the upper edge of each plastic partition plate are wrapped by an entire bend filter mesh (6); the bottom side on one side of the filter mesh (6) horizontally bends, bends upwards vertically, and then bends 180 degrees downwards to form a double-layered folded filter mesh partition layer (9), with the cross section in the U shape; the bottom side of the other side horizontally bends and rejects to the bottom of the adjacent filter mesh partition layer; the filter mesh is coated with a titanium dioxide coating; lamp holes are also opened on the plastic partition plates and the filter mesh, for the UV lamp tube to horizontally go through. Because the filter mesh wraps on both sides of the plastic partition plates, the soft filter mesh is supported, which saves labor and time in manufacturing and installation; the double-layered folded filter mesh partition layer increases the times of filtering and sterilization of the fluid, and the strength of the partition layer can also meet relevant requirements.

Description

technical field [0001] The invention relates to a sterilization and purification device for fluids such as gas and water using ultraviolet rays and titanium dioxide as photocatalysts. Background technique [0002] Existing use of UVC type ultraviolet lamps to irradiate TiO 2 Devices that sanitize and purify fluids by the photocatalytic effect created by the coating are mostly designed to pass the fluid back and forth through a limited number of layers coated with TiO 2 The coated filter screen is used to achieve the purpose of fluid disinfection and purification. In terms of specific structure, a baffle is used to separate a fluid channel back and forth in a box, and a filter screen is placed between the baffles. The ability of disinfection and sterilization, generally the partitions are made of stainless steel and coated with titanium dioxide on the surface. Due to the heavy and expensive stainless steel, the manufacturing cost remains high and the product is too bulky; S...

Problems solved by technology

[0002] Existing UVC ultraviolet lamps are used to irradiate TiO 2 The photocatalytic effect produced by the coating to disinfect and purify the fluid is mostly designed to allow the fluid to pass back and forth through a limited number of layers coated with TiO 2 Coated filter screens are used to achieve the purpose of fluid disinfection and purification. In terms of specific structure, partitions are used to form a tortuous fluid channel in a box, and there are filter screens between the partitions. In order to increase For the ability of disinfection and sterilization, the partitions are generally made of stainless steel and coated with titanium dioxide coating on the surface. Due to the heavy weight and high price of stainless steel, the manufacturing cost remains high and the product is too bulky; Soft, it is difficult to make it flat, which makes the production and installation time-consuming and not beautiful enough
