Description

Sterilization module

Technical Field

The utility model relates to a sterilization module especially relates to an utilize ultraviolet source to reach sterilization effect's sterilization module.

Background

Deep ultraviolet light refers to light having a wavelength of 200nm to 300nm, and is also called UVC. The deep ultraviolet can penetrate cell membrane and cell nucleus of microorganism, destroy genetic material such as DNA, RNA, etc., and kill microorganism. The deep ultraviolet ray can kill bacteria propagules, spores, viruses, fungi and the like, and is widely applied to water purification plants, hospitals, factories and the like as a broad-spectrum efficient sterilization means.

The traditional artificial deep ultraviolet light source is a mercury lamp tube, which contains heavy metal mercury, and is listed as a product needing to be eliminated by Water Authority. UVC-LED is as a novel artificial deep ultraviolet light source, relies on its advantages such as green, concentrated spectrum, flexible use, long-lived, has become the ideal choice of replacing traditional mercury fluorescent tube.

However, the above solution has the following disadvantages: 1. the sterilization rate is unstable. The rate of sterilization depends on the uv dose received by the microorganisms. The movement track of microorganisms in the water body is determined by water flow, and the more regular the water flow is, the more stable the flow rate is, the more stable the ultraviolet dose received by the microorganisms is, and the more stable the sterilization rate is. In the existing scheme, water flow in the sterilizer is in a turbulent flow state and is irregular. The ultraviolet dose received by the microorganisms in the water body is unstable, the randomness is high, and the sterilization rate is unstable. 2. The utilization rate of the deep ultraviolet light is low. The light utilization rate is the ratio of the power of the deep ultraviolet light which plays a role of sterilization to the power of the total incident light. The higher the illumination uniformity, the better the collimation of the light, the higher the light utilization. The UVC-LED light source part in the existing sterilizer only depends on one-time optical treatment and light source arrangement of the UVC-LED package, the requirements of light uniformity and collimation cannot be met simultaneously, and the light utilization rate is low. 3. The UVC-LED irradiation time is insufficient, and the sterilization effect cannot be achieved frequently. In the existing scheme, the UVC-LED packaging device is often disposed in a certain amount of space, and when a target object scheduled to be sterilized passes through the certain amount of space, due to the limitation of the space length, the irradiation time interval of the UVC-LED is often insufficient, and the target object passes through the certain amount of space, so that the situation of insufficient sterilization is caused.
