[0002] At present, ozone tail gas is the gas containing a small amount of ozone, which is usually discharged from the tail gas pipe on the top of the ozone contact tank, wherein in addition to ozone, it also contains a large amount of air or oxygen, and in order to avoid the pollution of ozone tail gas to the atmospheric environment, it is necessary to use the corresponding destruction mechanism to decompose and destroy the ozone tail gas into harmless gas.
[0003] However, when ozone tail gas is destroyed and decomposed at present, the gas is often heated to warm up and partially decomposed into oxygen in a short time for harmless emission, and when the gas is warmed up, the gas is only transported and accumulated in the corresponding tank body, and then the tank body is warmed up, and then the gas is discharged and transported, and such destruction and decomposition method not only excessively increases the warming energy consumption required for ozone tail gas destruction and decomposition, but also cannot decompose the gas in time during the gas transportation process, which affects the decomposition and destruction efficiency of ozone tail gas.
