Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature ozone disinfection, and particularly relates to an ozone disinfection device and a cold storage. Background Art

[0002] For current long-distance cargo transportation, after the goods arrive at the port, they need to undergo quarantine. After being confirmed safe, they can be warehoused, repackaged, or transferred. To ensure the safety of the goods during transportation and storage to the greatest extent, thorough disinfection is required before warehousing, repackaging, or transferring the goods after they arrive at the port, so as to prevent the spread and transmission of pathogenic microorganisms, and to ensure the safety of food transportation and cut off the transmission route of microorganisms through disinfection. Traditional disinfection methods such as ultraviolet irradiation and chemical disinfectant spraying have problems such as disinfection dead angles and disinfectant residues. Although ozone gas disinfection can ensure good disinfection effects, the strong oxidizing property of ozone is likely to corrode the equipment in the warehouse. When in use, the concentration and dosing time of ozone need to be strictly controlled, and the residual ozone needs to be removed after disinfection. Therefore, there is a need for a disinfection system that can quickly complete disinfection, has high reliability of disinfection effects, and is not affected by temperature, so as to meet the requirements of accelerating the flow rate of goods and improving safety.

[0003] The patent application with the publication number CN113041378A discloses a high-pressure atomizing ozone disinfection device, including: an ozone generating device, a gas-water mixing device, a gas pressurizing device, and a disinfection device. The first air outlet of the ozone generating device is respectively communicated with the first air inlet of the gas pressurizing device and the second air inlet of the gas-water mixing device. The first water outlet of the gas-water mixing device is communicated with the first water inlet of the disinfection device. The second air outlet of the gas pressurizing device is communicated with the third air inlet of the disinfection device. The second air inlet of the gas mixing device is also communicated with the decompression port of the disinfection device through a return air decompression pipe. This ozone atomizing disinfection device uses ozone gas for disinfection, but the control of the disinfection direction is not good, the disinfection effect is poor, and the residual ozone is easy to corrode other equipment.

[0031] Embodiment 1

[0032] As Figures 1 - 5 shown, this embodiment discloses an ozone disinfection device, including a box body 1, an air outlet assembly 2, an ozone generation device 3 and an atomization assembly 4.
