Description

UVC-LED and HEAP filter screen combined disinfection equipment

Technical Field

The invention belongs to the technical field of disinfection equipment, and particularly relates to disinfection equipment with a UVC-LED matched with a HEAP filter screen.

Background

Ultraviolet rays are classified according to wavelength, and can be classified into UVA long-wave ultraviolet rays (wavelength range 315-400 nm), UVB medium-wave ultraviolet rays (wavelength range 280-315 nm), UVC short-wave ultraviolet rays (wavelength range 200-280 nm) and VUV vacuum ultraviolet rays (wavelength range 10-200 nm). Wherein UVA long wave ultraviolet rays are also often referred to as near ultraviolet rays and UVC short wave ultraviolet rays are often referred to as deep ultraviolet rays.

Ultraviolet light is a mutagen that, at a specific wavelength range (mainly UVC) and at a sufficiently high dose, can cause abnormal chemical bonds between adjacent pyrimidine molecules of DNA or RNA in microbial cells such as bacteria and viruses, and inhibit the replication of the DNA or RNA, thereby causing microbial cell death.

When the ultraviolet rays irradiate the microorganisms, energy transfer and accumulation occur, and the accumulated result causes the inactivation of the microorganisms, thereby achieving the aim of disinfection. When the absorption of bacteria and viruses exceeds 3600-65000 uW/c square meter dose, the agent has strong destructive power to deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) of the bacteria and the viruses, and can lead the bacteria and the viruses to lose viability and fertility so as to further kill the bacteria and the viruses, thereby achieving the effect of disinfection and sterilization. Ultraviolet light can mutate nucleic acid, prevent the nucleic acid from being replicated, block transcription and synthesize protein; on the other hand, the generation of free radicals can cause photoionization, leading to cell death.

At present, a traditional UV mercury lamp is mainly used as an ultraviolet light source for ultraviolet air disinfection equipment.

Disadvantages of conventional UV mercury lamps: the appearance is heavy, the size is large, and the high-voltage power supply is arranged; the starting time is long, and the instant use cannot be realized; fragile, short service life, up to 90 percent of the service life is consumed in frequent switching phases; and the mercury can leak after the explosion, so that the environment is polluted, and the human health is seriously endangered.

In order to overcome the technical problems, meet the design requirements of the ultraviolet air disinfection equipment, improve the product design efficiency, and according to the characteristics of the ultraviolet disinfection equipment, the disinfection equipment combining the UVC-LED and the HEAP filter screen is disclosed.
