Problems solved by technology

But because the heating temperature cannot be too high, the purpose of thorough disinfection cannot be achieved. At present, there is no mature product that can effectively solve this problem. Disinfection is getting more and more attention
[0005] At present, ultraviolet lamp disinfection is being gradually applied in various fields. The existing ultraviolet air disinfection device is realized by setting one or several ultraviolet lamp tubes and adding a fan. Since the air flows through the ultraviolet radiation area for a short time, the ultraviolet dose is too low, far away The effect of sterilization cannot be achieved, and this device lacks a circulation channel with high ultraviolet illumination to ensure its ultraviolet dose

Embodiment 1

[0029] Embodiment 1: according to the appended figure 1 to attach image 3 As shown, the ultraviolet disinfection device described in Embodiment 1 includes a protective housing 1, an ultraviolet lamp 2, an air filter 4, an air inlet pipe 12, an air outlet pipe 10, and a blower fan 11, wherein the outer surface of the protective housing 1 is coated with Insulation coating, such as zirconia; the protective shell 1 is composed of half structural blocks 5 and 6 of two cylinders engraved with a spiral channel structure pipe groove 3, and the spiral ultraviolet lamp 2 is placed in the spiral channel Inside the structural tube groove 3; the inside of the tube groove 3 can be coated with an ultraviolet reflective coating, specifically polished aluminum, polished molybdenum, aluminum oxide or magnesium oxide. The diameter of the ultraviolet lamp 2 is smaller than the diameter of the spiral passage structure pipe groove 3, and the air inlet pipe 12 and the outlet pipe 10 are correspond...

Embodiment 2

[0031] Embodiment 2: According to the attached Figure 4 to attach Image 6 As shown, the protective housing 1 of this embodiment is composed of three structural blocks 7, 8, and 9. There is a half U-shaped pipe groove 13 in the structural block 7, and there are symmetrical half U-shaped pipe grooves 13 on both sides of the structural block 8. Shaped pipe groove, one of the end sections 15 between the two half pipe grooves communicates to form an air flow channel, and the structural block 9 is engraved with a half U-shaped pipe groove 14, the total length of a single U-shaped pipe groove is 0.9m, and can be built in φ19mm150W low-pressure high-strength Ultraviolet lamps, 16 ozone-free 150W low-pressure high-intensity ultraviolet lamps are installed between structural blocks 7 and 8, 17 ozone-free 150W low-pressure high-intensity ultraviolet lamps are installed between structural blocks 7 and 9, and the diameters of pipe grooves 13, 14, and 15 are φ150mm , the inner wall can b...

Abstract

The invention provides a high-efficiency air disinfecting and sterilizing method and a device thereof. In the method, an ultraviolet lamp with a corresponding shape is arranged in an air ventilating pipeline, wherein an air flow pipeline is designed to be a bent pipe chase structure at first, so that the ultraviolet radiation time is increased; according to the speed of an air flow, the ultraviolet radiation time is controlled to be between 0.2 and 2s, and a low-voltage high-strength ultraviolet lamp is adopted simultaneously to improve the ultraviolet illumination intensity in the pipeline; according to the size of the pipeline, the ultraviolet illumination intensity is controlled between 5 and 50Mw / cm<2> to guarantee that the air ultraviolet radiation dosage flowing through the pipeline is more than 5mJ / cm<2>(mW.s / cm<2>), so that the aims of killing bacteria and viruses at one time and purifying air are achieved, and the ultraviolet dosage to special bacteria and viruses can be increased to 15mJ / cm<2> or even more. By utilizing the design of the bent pipe chase structure, the volume of a disinfection device can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of ultraviolet disinfection, in particular to an efficient air disinfection and sterilization method [0002] and its devices. Background technique [0003] Air disinfection mainly includes ultraviolet disinfection and ozone disinfection. Ultraviolet rays can penetrate the cell membrane and nucleus of microorganisms, destroy the molecular bonds of nucleic acids, and make them lose their ability to replicate or lose their activity. Since cells cannot replicate, microorganisms will soon die. Achieve the effect of killing bacteria and viruses. The 253.7nm ultraviolet disinfection in the hospital clinics and wards needs to avoid the ultraviolet radiation damage of people indoors; in addition, the existing ultraviolet disinfection devices do not have a suitable air circulation system, and the bacteria and viruses far away from the ultraviolet lamp receive a low dose of ultraviolet radiation. At the same time, u...
