High-energy pulse ultraviolet space sterilization device

Abstract

The invention discloses a high-energy pulse ultraviolet space sterilization device, and belongs to the technical field of indoor disinfection and sterilization equipment. The sterilization device comprises a case and a high-energy pulse ultraviolet lamp component arranged above the case, wherein a hole is formed in the top of the case; an elevator and a driving energy system are arranged inside the case; a control module is arranged outside the case; the bottom of the high-energy pulse ultraviolet lamp component penetrates through the hole formed in the top of the case to be connected with the elevator; the high-energy pulse ultraviolet lamp component comprises a plurality of modulator tubes and a plurality of pieces of vitaglass which are alternately arranged; the modulator tubes are inverted u-shaped tubes; the two ends of each of the modulator tubes are sealed by transition material tubes; a cerium-doped quartz glass tube is externally arranged on each of the transition material tubes; a cerium-tungsten electrode penetrates through the bottom of each corresponding cerium-doped quartz glass tube into the each corresponding modulator tube; xenon gas is aerated in the modulator tubes. According to the sterilization device, pulse ultraviolet a hundred times higher than the conventional ultraviolet lamp can be emitted to kill the microorganisms in the air and a direct surface, and ozone can be generated for performing disinfection and air purification on backlight and gap parts.

Description

technical field [0001] The invention belongs to the technical field of indoor disinfection and sterilization equipment, and in particular relates to a high-energy pulse ultraviolet space disinfection device. Background technique [0002] The current mainstream indoor disinfection and sterilization methods include ultraviolet irradiation, ozone fumigation, hydrogen peroxide spray, formaldehyde fumigation and other methods. These methods have their limitations and cannot fully meet the sterilization needs of all occasions. The main sterilization methods are as follows: [0003] 1. Ultraviolet irradiation method [0004] The principle of ultraviolet sterilization is to destroy and change the DNA (deoxyribonucleic acid) structure of microorganisms through ultraviolet radiation, so that the bacteria will die immediately or cannot reproduce offspring to achieve the purpose of sterilization. It is UVC ultraviolet rays that really have a bactericidal effect, because C-band ultravi...

AI Technical Summary

Problems solved by technology

Its limitations are: first, the power of ultraviolet lamps is generally small, so the space layout of 30w / square meter lamp tubes is not suitable for all spaces; second, the effective distance of ultraviolet light is only 50cm, which is not suitable for indoor space disinfection; third, the time requirement for ultraviolet disinfection Longer, generally more than 30 minutes, not suitable for spaces that require fast turnover

However, formaldehyde itself is a toxic gas and has a risk of cancer

And it is not easy to decompose and remove, and there are often residues after disinfection

In addition, formaldehyde fumigation takes more than 4 hours, which is not suitable for occasions that require rapid disinfection
