Cargo disinfection and sterilizing device and disinfection and sterilizing method

Abstract

The invention relates to the technical field of disinfection and sterilizing, and particularly relates to a cargo disinfection and sterilizing device and a disinfection and sterilizing method. The cargo disinfection and sterilizing device comprises a disinfection and sterilizing cavity, a degradation cavity and a conveying belt, wherein a plurality of oxidation dry fog disinfection modules are arranged in the disinfection and sterilizing cavity; a degradation module is arranged in the degradation cavity; the conveying belt passes through the disinfection and sterilizing cavity and the degradation cavity to transport cargos; the oxidation dry fog disinfection modules generate ozone and hydroxyl radical mixed dry fog in the disinfection and sterilizing cavity; and the degradation module is used for degrading ozone in the degradation cavity. The cargo disinfection and sterilizing device and the disinfection and sterilizing method aim at achieving the goal of preventing the epidemic disease propagation by converting most of gaseous active substance ozone into gas-liquid mixed dry fog containing active oxygen and hydroxyl radicals and using the dry fog for disinfecting and sterilizing the cargos; meanwhile, a photoelectric coupling degradation module is additionally arranged inside the device; through the combination with a photoelectric coupling unit, excessive ozone generated along with the dry fog is thoroughly degraded; and the ozone leakage hidden danger is thoroughly eliminated.

Description

technical field [0001] The invention belongs to the technical field of disinfection and disinfection, and in particular relates to a cargo disinfection device and a disinfection method. Background technique [0002] In the case of low temperature, some bacteria and viruses are easy to adhere to the goods, especially on the surface of cold chain goods, and can survive for a long time, increasing the risk of secondary transmission; The society urgently needs relevant response plans and equipment for the spread of epidemics caused by logistics and the flow of personnel and luggage. [0003] The molecular structure of ozone is unstable at normal temperature and pressure, and it will quickly decompose into oxygen (O2) and a single oxygen atom (O); the latter has strong activity and strong oxidizing ability, and can directly act on bacteria, viruses and Volatile organic gases play a role in sterilization and air purification. In practical applications, simple ozone disinfection ...

Problems solved by technology

[0006] In order to solve the problem that there are bacteria and germs on the transported goods, especially for cold chain goods, there is no effective equipment to quickly disinfect them. The present invention provides a goods disinfecting device and a disinfecting method. While the goods are being transported, the goods are sterilized by the mixed dry fog of ozone and hydroxyl radicals, and the generated ozone is degraded after the sterilizing is completed, so that the ozone will not overflow the outside of the device, which solves the problem of secondary pollution and common disinfection. In the disinfecting method, the problem of chemical residue
