technical field

The invention relates to the field of ozone disinfection, in particular to a cabinet type ozone disinfection machine.

Background technique

Ozone, also known as triatomic oxygen, is a strong oxidant, which can be used in the field of air disinfection to oxidize and decompose the enzymes needed to decompose glucose in bacteria in the air, so that bacteria can be inactivated and killed. Its preparation can be realized by dielectric barrier discharge method (abbreviated as DBD method). A corona is generated in the gas by an alternating high-voltage electric field, and the free high-energy electrons in the corona dissociate the oxygen molecules, which are polymerized into ozone molecules by collision. The dielectric barrier discharge method has relatively low energy consumption, large ozone output per unit, and the gas source can be dry air, oxygen or oxygen-rich gas with high oxygen concentration. Therefore, this method is mostly used for industrial ozone synthesis.

In the existing indoor ozone disinfection device, because the DBD module lacks a cooling device, the temperature of the DBD reactor is always kept at a high state during operation, which is easy to cause the electrode plate to break down for a long time, resulting in a greatly reduced service life; The accumulation around the DBD reactor affects the generation of ozone; the ozone is generated on one side of the device, and the degree of mixing with the air is low, and the ozone cannot be discharged evenly during discharge; in addition, the fan inside the ozone disinfection device will adhere to dust after long-term operation, resulting in the effect of ventilation Not good, it will also affect the uniform discharge and diffusion of ozone. Therefore, improvements are made for the above problems.
