Low-temperature plasma NO adsorption and catalysis device

The utility model belongs to the technical field of plasma adsorption catalysis devices, and particularly relates to a low-temperature plasma adsorption catalysis NO device which comprises a processing box, a pre-dedusting component comprises a dust adsorption pipe communicated with an air inlet pipe, and the front end of the dust adsorption pipe is connected with a corrugated pipe communicated with an air supply end. The exhaust component is connected to the end of the exhaust pipe and further monitors and outputs exhausted gas, dust and impurity removal operation is carried out on flue gas through the arranged dust adsorption pipe, dust or impurities are prevented from being directly conveyed into the treatment box through the gas inlet pipe, damage to elements in the treatment box is avoided, and the conveyed gas is discharged into the storage box after being treated by the treatment box, so that the environment is protected. The gas concentration information is monitored in real time through the gas senso
