Ultraviolet ray inactivation apparatus and water purifier

Abstract

The present invention provides an ultraviolet ray inactivation apparatus and a water purifier. The ultraviolet ray inactivation apparatus comprises: a flow falling pipe, wherein the flow falling pipe presents a translucent three-dimensional helical structure, is provided with a flow inlet and a flow outlet, and is used for overflowing of a fluid inactivated by ultraviolet ray; a broad-spectrum ultraviolet ray lamp group, wherein the broad-spectrum ultraviolet ray lamp group comprises one or a plurality of ultraviolet ray lamps, is arranged in the space limited by the three-dimensional helical structure of the flow falling pipe, and is used for radiating ultraviolet rays toward the fluid in the flow falling pipe so as to perform inactivation operation; and a power supply for supplying power for the ultraviolet ray lamp group according to the condition of the fluid in the flow falling pipe. According to the ultraviolet ray inactivation apparatus of the present invention, the broad-spectrum inactivation is achieved while the ultraviolet ray inactivation frequency spectrums can be selected and combined so as to improve the targeting property, the reliability and the safety of the inactivation treatment; and the radiation intensity of the ultraviolet rays can be adjusted according to the fluid condition so as to ensure the inactivation effect and the energy consumption utilization efficiency.

Description

technical field [0001] The invention relates to the technical field of ultraviolet inactivation, in particular to an ultraviolet inactivation device and a water purifier. Background technique [0002] Ultraviolet rays are divided into multiple bands according to wavelengths, and ultraviolet rays in different bands will inactivate different types of bacteria or viruses, thereby achieving a sterilization effect. Utilizing this characteristic of ultraviolet rays, various living harmful substances such as drinking water, industrial sewage, or animal and plant body fluids can be eliminated in a targeted manner. [0003] At present, the existing ultraviolet inactivation devices often only use ultraviolet rays in a certain band for inactivation, resulting in a single application range. For example, the existing household ultraviolet water purifiers are all for drinking water and tap water. Considering the inactivation of animal and plant body fluids such as milk, fruit juice, etc....

AI Technical Summary

Problems solved by technology

In this case, if the flow rate of the fluid is too large, the contact time between the fluid and the ultraviolet rays will be reduced, resulting in poor inactivation effect; on the contrary, if the flow rate of the fluid is too small, the power of the ultraviolet inactivation device will be "overqualified". "problem, resulting in energy waste
