[0002] At present, the denitration system of the daily glass industry generally adopts SCR flue gas denitration technology, such as an SCR denitration device with Chinese patent application number CN202123405816.7, which includes a bracket, and the main body is tiltedly installed on the bracket. The main body includes a box body, and a smoke inlet and a smoke outlet are respectively opened at both ends of the box body. A plurality of grouped dust removal devices and denitration catalysts are sequentially arranged in the box body along the flow direction of the airflow. The dust removal device includes a steam pipe and an ash guide trough. The steam pipe is provided with a nozzle, and the nozzle faces the denitration catalyst and is consistent with the flow direction of the airflow. The ash guide trough is arranged along the inner wall of the box body to collect the blown dust. This device is provided with a steam dust removal device. During the operation of the device, the dust attached to the denitration catalyst is sprayed. The sprayed dust is automatically collected and discharged by the conveyor, which solves the problem of blockage of the denitration catalyst. The dust removal process does not require shutdown for manual cleaning, which ensures the denitration effect and extends the service life of the denitration catalyst.
