Fluid Sterilization Device

Abstract

The invention discloses a fluid sterilizing device. The fluid sterilizing device comprises a sterilizing unit. The sterilizing unit comprises an ultraviolet light guiding body, a first reflection piece for reflecting ultraviolet light towards the ultraviolet light guiding body and an ultraviolet generating device arranged between the ultraviolet light guiding body and the first reflection piece, and a plurality of micro-pore channels for fluid to pass through are formed in the ultraviolet light guiding body. The fluid is refined into tiny micro-columns through micro-pore columns, macroscopical fluid is divided into microcosmic columns, the microcosmic columns receive ultraviolet irradiation, ultraviolet light directly acts on bacteria in the fluid, the required dose is much smaller than the dose adopted during macroscopic illuminating, and the sterilizing efficiency is improved; as the micro-pore channels are formed in the ultraviolet light guiding body, the area of outlet light towards the micro-pore channels can be increased, the outgoing efficiency of ultraviolet light is improved, the bacteria in the fluid rapidly absorb more ultraviolet light and are damaged, the sterilizing efficiency is improved, and as the first reflection piece is arranged, the using rate of ultraviolet light is increased.

Description

technical field [0001] The invention belongs to the technical field of sterilization, and in particular relates to a fluid sterilization device. Background technique [0002] Most of the current air sterilization devices add deep ultraviolet lamps on the side walls or ends of the air passages to irradiate the air in the air passages. The bacteria in the air absorb deep ultraviolet rays and their RNA is destroyed, reducing the number of bacteria. However, there are requirements for building ventilation. The flow rate of air in the ventilation channel is very fast. Bacteria move with the air and leave the light area quickly. Therefore, the light dose received by most bacteria is not enough to destroy their RNA. Bacteria are still Can grow and reproduce, so the existing air sterilization effect is not very ideal. Similarly, running water sterilization also has the problem of unsatisfactory sterilization effect. The existing ultraviolet sterilization module has the problems of...

Problems solved by technology

However, there are requirements for building ventilation. The flow rate of air in the ventilation channel is very fast. Bacteria move with the air and leave the light area quickly. Therefore, the light dose received by most bacteria is not enough to destroy their RNA. Bacteria are still Can grow and reproduce, so the existing air sterilization effect is not very ideal

Similarly, running water sterilization also has the problem of unsatisfactory sterilization effect

The existing ultraviolet sterilization module has the problems of low light extraction efficiency, low sterilization efficiency and low energy utilization rate
