Description

Technical Field

[0001] The present invention relates to the technical field of disinfection and sterilization equipment, and specifically to a DBD plasma disinfection and sterilization treatment system. Background Art

[0002] For plasma disinfection, a bipolar plasma electrostatic field is used to decompose and break down bacteria carrying negative charges, polarize and adsorb dust, and then components such as a drug-impregnated activated carbon, an electrostatic net, and a photocatalyst catalytic device are combined for secondary sterilization and filtration. The treated clean air circulates rapidly in large quantities, keeping the controlled environment up to the standard of an "aseptic and dust-free room". As a new and fast sterilization method, the sterilization principle of a low-temperature plasma jet includes multiple different sterilization mechanisms, including charged particles, active particles, and free radicals (oxygen atoms, hydroxyl groups, reactive oxygen species, reactive nitrogen species), high-energy ultraviolet rays in the VUV and UVC bands, the thermal effect generated by the discharge, the bombardment of charged particles, an alternating electric field, and physical and chemical corrosion processes. The active particles carried by the plasma jet will greatly damage the integrity of cells, ultimately leading to the inactivation of microorganisms.

[0003] In the prior art, a DBD plasma disinfection, insecticidal, and sterilization treatment device with the application number 202411482629.4 includes a first electrode plate. Air is efficiently conveyed between the first electrode plate and the second electrode plate by a first fan to decompose ozone, and the ozone is used to kill pests and bacteria, thus improving the problem that traditional grain depot disinfection often uses ultraviolet disinfection, resulting in low disinfection efficiency. However, it is necessary to cycle items in and out of the cabinet for disinfection, which is time-consuming and laborious, and the continuity of disinfection and sterilization is poor, thus affecting the efficiency of continuous disinfection and sterilization of multiple items.
