Night external light lamp irradiation range adjusting frame based on sewage treatment photocatalysis principle

Abstract

The invention relates to sewage treatment equipment, in particular to a night external light lamp irradiation range adjusting frame based on a sewage treatment photocatalysis principle. The frame comprises a double-groove guide plate, a slide rail, a connecting rod and the like, the two slide rails are fixedly installed on the double-groove guide plate, the two connecting rods are installed in sliding grooves of the sliding rails in a sliding mode, an ultraviolet lamp holder left-right moving mechanism is installed on one sides of the connecting rods, and an ultraviolet lamp holder front-backmoving mechanism is installed on the double-groove guide plate and the ultraviolet lamp holder left-right moving mechanism. According to the ultraviolet lamp holder left-right moving mechanism, a connecting frame and a swing connecting shaft rod can be driven to swing through rotation of a swing rod, so that the ultraviolet lamp slides on a T-shaped guide rod, the ultraviolet lamp holder front-back moving mechanism works in cooperation to enable the ultraviolet lamp to move left and right in a sewage pool, and ultraviolet light irradiation on all positions of the sewage pool is achieved.

Description

technical field [0001] The invention relates to sewage treatment equipment, and more particularly relates to a frame for adjusting the range of irradiation of external lights at night based on the principle of photocatalysis for sewage treatment. Background technique [0002] The principle of photocatalysis is based on the redox ability of photocatalysts under the condition of light, so as to achieve the purpose of purifying pollutants, material synthesis and transformation, etc. Usually, photocatalytic oxidation reactions use semiconductors as catalysts and light as energy. The degradation of organic matter into carbon dioxide and water, photocatalytic technology, as an efficient, safe and environmentally friendly environmental purification technology, is becoming a research hotspot in the field of environment. [0003] With the development of the economy, water pollution is becoming more and more diversified. The discharge of pollutants such as untreated industrial wastewa...

Problems solved by technology

[0004] The object of the present invention is to provide a night-time external light lamp irradiation range adjustment frame based on the principle of sewage treatment photocatalysis that can adjust the irradiation range of ultraviolet lamps and stir up and down the photocatalyst in the sewage pool, so as to solve the problem that the existing ultraviolet lamps are generally fixed. Installed in one place, the irradiation range is limited and cannot irradiate every part of the sewage pool, and the depth of the pool and the water quality of the sewage pool affect the penetration of ultraviolet light in the sewage pool, and the penetration of ultraviolet light decreases with the increase of the depth of the sewage pool force and reduce the efficiency of photoelectric conversion with titanium dioxide, and the problem of uneven sewage treatment efficiency
