SCR denitration catalyst sweeps device on line in real time

The utility model belongs to the technical field of gas cleaning, a SCR denitration catalyst sweeps device on line in real time is proposed. A plurality of albums of casees that's a SCR denitration catalyst sweeps device on line in real time have with SCR denitration reactor in the setting of multilayer catalyst bed one -to -one is proposed, a plurality of cargo position that collect are outside SCR denitration reactor, a plurality of albums of casees all with SCR denitration reactor in preheating device's export be linked together, preheating device's import intercommunication dehumidifier, dehumidifier intercommunication compressed air tank, compressed air tank is linked together with the air supply, every collection case is linked together with a plurality of pipes that sweep of parallel arrangement before the catalyst bed that corresponds, compressed air after a plurality of albums of casees will heat sends into and sweeps the pipe, sweeps the catalyst bed. The utility model discloses having practiced thr
