Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a bag dust removal device for a boiler ash bin. Background Art

[0002] The bag dust removal device, also known as a bag filter or bag-type dust collector, is an important dust removal equipment and is widely used in many industrial fields such as iron and steel, cement, chemical industry, and electric power.

[0003] When removing dust from the boiler ash bin, the PLC controller is used to receive the air volume and pressure sensor signals or timing control signals in front of the bag, and control the opening and closing of the solenoid valve at the air inlet pipe according to the preset logic, so as to control the spraying action. The small spraying system of the bag dust removal device for the boiler ash bin uses the PLC as the control core and realizes two spraying methods, namely timing spraying and pressure spraying, through software programming. The timing spraying is carried out according to the set time interval of the system, and the pressure spraying mode judges whether to spray according to the differential pressure before and after the bag. If the wind pressure reaches the set threshold value, the air compressor is started and the spraying valve on the spraying pipe is opened to make the spraying program until the wind pressure drops to the set lower limit value. Then the dust will pass through the fan and solenoid valve on the air inlet pipe to reach the inside of the box body and be dust-removed by the bag. The dust-removed air is discharged through the air outlet pipe.

[0004] When using the air inlet pipe, more equipment is installed at the air inlet pipe to control the entry of dust into the box body, resulting in a greater weight at the air inlet pipe. After the air inlet pipe is stressed, the air inlet pipe bends and deforms, thus affecting the use effect of the bag dust removal device. Summary of the Utility Model

The small blowing system for bag dust removal in the boiler ash bin uses PLC as the control core, and realizes two blowing methods, namely timing blowing and pressure blowing, through software programming. Timing blowing is carried out according to the set time interval of the system. In the pressure blowing mode, it is judged whether to blow according to the differential pressure before and after the cloth bag. If the wind pressure reaches the set threshold value, the air compressor is started and the blow valve on the blowpipe is opened to make the blowing program until the wind pressure drops to the set lower limit value.
