Embodiment Construction

[0023] The present invention will be further described below in conjunction with specific examples.

[0024] Such as figure 1 The submerged photocatalytic reaction device shown includes four photocatalytic tubes 1, each photocatalytic tube 1 is connected to the water outlet pipe 2 and the water inlet pipe 3 respectively, the photocatalytic tube is cylindrical, and the arrangement in the tube body of the photocatalytic tube is With UV lamp 4 and titanite TiO 2 The film 5 is formed, and the ultraviolet lamp can emit ultraviolet light with an emission wavelength of about 380nm.

[0025] When in use, the photoelectric catalytic reaction device is immersed in the bottom of the river, water enters the photocatalytic tube from the water inlet pipe, and the ultraviolet light emitted by the ultraviolet lamp and the TiO 2 After the synergistic catalytic reaction of the film is purified, it is discharged from the outlet pipe.

Abstract

The invention relates to an apparatus used for sterilizing, removing algae and purifying water quality, and especially relates to an immersed type photoelectrocatalysis reaction apparatus. The photoelectrocatalysis reaction apparatus comprises various roots of photoelectrocatalysis pipes, the photoelectrocatalysis pipes are respectively connected with an outlet pipe and an inlet pipe. The immersed type photoelectrocatalysis reaction apparatus is formed by independent photoelectrocatalysis pipes, the reaction apparatus with different sizes having different numbers of photoelectrocatalysis pipes can be produced according to different water body area and water quality condition, the pipe number can be set in an adjustable mode, and can be 4, 8 and the like (4n, n>=1). According to the invention, TiO2 is employed to prepare a film, the disadvantages that nano powder is not easy to separate with the water body can be overcome, a lot of engineering practices prove that the photoelectrocatalysis reaction apparatus has simple structure, the treatment effect is good, the operation is simple, no secondary pollution is generated, and the photoelectrocatalysis reaction apparatus is effective to remove the algae of the eutrophication water body. The photoelectrocatalysis reaction apparatus has the advantages of compact structure, less land occupation area, less energy consumption, no chemical agent addition, low operation cost and large treatment amount.

Description

technical field [0001] The invention relates to a device for sterilizing, removing algae and purifying water, in particular to a submerged photoelectric catalytic reaction device. Background technique [0002] The photoelectric catalytic reaction device is a device that uses the principle of photocatalytic reaction to sterilize, weed and purify water. Photocatalysis refers to the process in which nano-semiconductor materials promote the decomposition or synthesis of compounds under the irradiation of light, in which TiO 2 It has become the focus of photocatalytic research because of its high catalytic activity, good stability, non-toxicity to the human body, continuous light can maintain activity and other advantages. TiO 2 Photocatalytic performance has the ability to purify almost all organic pollutants. The 114 kinds of organic pollutants announced by the US Environmental Protection Agency are treated with TiO under light. 2 As a catalyst, it can be gradually degraded...
