Low-temperature ozone disinfection refrigeration house system applied to cold-chain articles

Abstract

The invention provides a low-temperature ozone disinfection refrigeration house system applied to cold chain articles. The low-temperature ozone disinfection refrigeration house system applied to the cold chain articles comprises a closed refrigeration house, the temperature inside the closed refrigeration house is adjustable and controllable, further comprises an ozone gas supply device, an ozone adding system, a gas mixing device, an ozone internal circulation destroying device, an ozone tail gas destroying device, an ozone concentration monitoring device and a control system; the refrigeration house is used for placing cold chain articles to be disinfected during disinfection and is provided with one or more sealing doors, and the ozone adding system, the gas mixing device and the ozone internal circulation destroying device are mounted in the refrigeration house; the ozone gas supply device is connected with the ozone adding system, and a plurality of ozone adding openings are formed in the ozone adding system and used for uniformly spraying ozone gas or aerial fog into the refrigeration house; the gas mixing device is used for keeping the ozone concentration at all positions in the refrigeration house uniform; the ozone internal circulation destroying device is used for rapidly destroying ozone in the refrigeration house when disinfection is finished; the ozone tail gas destroying device is used for eliminating residual ozone in exhausted gas and keeping pressure inside and outside the refrigeration house balanced.

Description

technical field [0001] The invention relates to the field of disinfection of cold chain items, in particular to a low-temperature ozone disinfection cold storage system applied to cold chain items, and belongs to the technical field of disinfection. Background technique [0002] With the development of society and economy, people's living standards are gradually improving, and various goods, especially cold chain items, have been circulated globally. The goods or their outer packaging are easily contaminated with some bacteria and viruses during production and circulation, including some Pathogenic microorganisms will continue to proliferate under suitable environmental conditions. If they are not disinfected, they will seriously endanger the health of those who come into contact with them, and even cause the spread of pathogenic microorganisms on a large scale, posing a great risk to human life and environmental safety. [0003] Taking customs or ports as an example, there ...

AI Technical Summary

Problems solved by technology

[0005] Existing goods are usually disinfected by spraying chlorine-containing disinfectants, but it needs to fully spray the outer surface of each goods. In order to achieve the disinfection effect, it is necessary to move the goods so that all surfaces are fully sprayed, which increases the workload and disinfection. time, it is easy to cause incomplete disinfection due to insufficient spraying or waste of excessive spraying, and it may also cause secondary pollution to the environment
