Problems solved by technology

[0003] However, it has been found in practice that for most water purification devices, the volume of the ultraviolet purification device is limited, resulting in a limitation of the time for water to pass through the ultraviolet purification device, that is, the realization of fluid disinfection through ultraviolet radiation still has short exposure time of the fluid to the ultraviolet radiation source, Problems with uneven doses of UV radiation, preventing complete disinfection of fluids

Embodiment 1

[0036] Embodiment 1, the housing 100 is provided with one or more fluid conduits 200 .

Embodiment 2

[0037] In Embodiment 2, the front and rear ends of the casing 100 are an inlet 101 and an outlet 102 respectively, the inlet 101 corresponds to the water inlet 201 , and the outlet 102 corresponds to the water outlet 202 .

[0038] The shell 100 is narrow at the front and rear ends and wide at the middle, and the bending radius at the front and rear ends of the helical structure 210 is small, and the bending radius at the middle is large. It is equivalent to the diameter of the helical bend of the helical structure 210 of the fluid pipeline 200. From the water inlet hole 201 to the water outlet hole 202, it shows a trend of first increasing and then decreasing. The maximum value, the fluid flow distance at the center is the longest, which can significantly increase the time of the fluid at the position of high ultraviolet radiation energy density.

[0039] The fluid pipeline 200 is distributed in an extended helical structure 210 , and the low-calorie fluid passed through it t...

Embodiment 3

[0045] Embodiment 3, the casing 100 is provided with one or more inlets 101 .

Abstract

The invention discloses an overflowing extension type ultraviolet disinfection reactor which comprises a shell, a fluid pipeline is arranged in the shell, and a water inlet hole and a water outlet hole are formed in the front end and the rear end of the fluid pipeline respectively; the fluid pipeline is wound and bent to form a spiral structure, and a point radiation source is arranged on the inner side of the spiral structure. By adopting the overflowing extension design that the spiral structure surrounds the point radiation source, not only can the temporary retention time of water flow in the disinfection chamber be prolonged, but also ultraviolet rays emitted by the point radiation source can fully irradiate the fluid pipeline, and the disinfection effect on water is ensured.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to an overcurrent extension type ultraviolet disinfection reactor. Background technique [0002] Water is an essential material for people's production and life, and the purification of water is becoming more and more important, especially the water contains pathogens, which must be purified in time to prevent disease transmission and maintain the health of the crowd. In the prior art, the following methods are commonly used for disinfection of domestic water: 1. Physical methods, such as ultrasonic disinfection, heating, etc.; 2. Chemical methods: chlorine addition, ozone, heavy metal ion methods and other oxidizing methods. However, the scope of heating and ultrasonic disinfection is limited, and the chemical substances in chemical methods have negative impacts on the environment, including the toxicity of water, the danger of organic chlorine, and the resistance of vir...
