L-shaped ultraviolet irradiation algae suppression device

Abstract

The invention discloses an L-shaped ultraviolet irradiation algae suppression device. The device comprises a housing, an ultraviolet lamp assembly, a magnetic suction type cleaning assembly, a liquidinlet, a liquid outlet and a liquid discharge port; the ultraviolet lamp assembly is mounted at a central position in the housing in the length direction of the housing, and the magnetic suction typecleaning assembly sleeves the ultraviolet lamp assembly; the liquid inlet is formed in the middle of a first end of the housing; the liquid outlet is formed in the portion, at a second end opposite tothe first end, of the housing, wherein the second end is close to the housing; the liquid discharge port is formed in the housing, the liquid inlet is communicated with the liquid outlet, liquid enters from the liquid inlet in the length direction of the housing and flows out from the liquid outlet, and an L-shaped liquid flow direction is formed in the housing. By means of the device, the purposes of inhibiting the growth of bloom algae and preventing algal bloom can be achieved.

Description

technical field [0001] The invention relates to a technique for inhibiting algae growth, in particular to an L-type ultraviolet radiation algae inhibiting device. Background technique [0002] Human production and life will produce a large amount of nitrogen, phosphorus and other nutrients. When they enter lakes, reservoirs and other water bodies, they will cause the rapid reproduction of algae and phytoplankton, resulting in the death of fish, shellfish and other aquatic organisms in the water body. Diversity and stability are reduced, leading to deterioration of water quality, which in turn leads to eutrophication of water bodies. my country's main rivers, such as the Yangtze River, Yellow River, Pearl River, Songhua River, etc., and some large lakes, such as Taihu Lake, Poyang Lake, Chaohu Lake, East Lake and Dianchi Lake, have all experienced algal blooms and outbreaks. The occurrence of algae blooms will bring serious water pollution. The outbreak of algal blooms will ...

AI Technical Summary

Problems solved by technology

[0004] (1) The turbidity of algae liquid and suspended solids in water have a great influence on the inhibition of algae growth by ultraviolet radiation, which reduces the algae inhibition effect of ultraviolet lamps

[0005] (2) When the ultraviolet lamp is irradiated for a long time, the ultraviolet lampshade is easy to scale, and the algae are easy to settle and attach to the lampshade, which affects the penetration of ultraviolet light and the effect of algae inhibition

[0006] (3) The conventional static ultraviolet irradiation algae suppression device, when providing continuous irradiation operation, the algae is easy to condense and settle, and deposits on the ultraviolet lampshade, and due to the lack of flow mixing, it leads to dark areas far away from the light irradiation of the ultraviolet lamp, The algae inactivation effect is poor, and the algae that is closer to the ultraviolet lamp are exposed to excessive radiation, the cells will rupture, and the contents of the cells will leak out to cause secondary pollution, which is not conducive to the uniform inhibition and inactivation of algae.

[0007] The above shortcomings reduce the effect of ultraviolet irradiation technology on algae inhibition, which is not conducive to the inhibition of algae blooms before the occurrence of water blooms, and is also not conducive to the early prevention of water blooms to a certain extent.
