The working principle is as follows: firstly, separating cement dust from water vapor in dust-containing air, then utilizing part of clean air discharged by a centrifugal fan 19, heating the clean air by a heater 14, then entering a dust removal chamber, carrying out back flushing on the outer surface of a pasted filter cylinder 8 by an internal pulse back flushing ash remover 9, drying the cement dust adhered to the outer surface of the filter cylinder 8 by the clean air continuously passing through air, generating chap on a dried powder cake under the action of internal stress, and then generating vibration and shake-off under the back flushing of pulse back flushing airflow to achieve the purpose of removing the paste adsorbed on the outer surface of the filter cylinder 8 and ensure the normal work of the dust remover of the filter cylinder 8.
When the first dust-removing chamber 5 works, the pulse back-blowing ash remover 9 of the second dust-removing chamber 6 enters back-blowing drying dust removal; when the second dust-removing chamber 6 works, the pulse back-blowing ash remover 9 of the first dust-removing chamber 5 enters back-blowing drying dust removal. The working process is as follows:
when the dust removing system is in the working state of the first dust removing chamber 5 and the pulse back-blowing ash remover 9 of the second dust removing chamber 6 enters the back-blowing drying dust removing,
the pneumatic valve 13 of the air inlet line 1 on the first dust removal chamber 5 is fully opened, i.e. the pneumatic valve 13V1 is fully opened;
the pneumatic valve 13 of the air inlet line 1 on the second dust removal chamber 6 is fully closed, i.e. the pneumatic valve 13V2 is fully closed;
the control valve 12 at one end of the circulating pipeline 7 connected with the first dust removing chamber 5 is fully closed, namely the control valve 12V3 is fully closed;
the control valve 12 at one end of the circulating pipeline 7 connected with the second dust removing chamber 6 is fully opened, namely the control valve 12V4 is fully opened;
the ash discharge valve 11 on the ash discharge pipeline 2 of the ash bucket 10 below the first dust-removing chamber 5 is fully opened, namely the ash discharge valve 11V5 is fully opened;
