Description
Technical field
The present invention relates to garbage-incineration smoke purifying technical field, specially pulse dust cleaning controller, with the controller
Control device and control method.
Background technology
Deduster is a kind of equipment that dust can be separated from flue gas, the accessible gas of performance of deduster
Drag losses and efficiency of dust collection when the scale of construction, gas are by deduster are expressed, and deduster is also waste incineration, boiler and industry
Common equipment in production, can deduster safely and steadly run has higher requirement, therefore deashing control to dust-removing control
The technical merit of device processed is not only the importance of deduster overall technology level, is also directly related to the use effect of deduster
Fruit；Wherein, dusty gas be in being entered by deduster air inlet, lower box, dusty gas enters upper box mistake by filter bag
Dust and gas is separated since the various effects of filter bag act in journey, dust is attracted on filter bag, and gas passes through filter bag scripture
Family name's pipe enters upper box, is discharged from air outlet, and dusty gas accumulates as time increases in the purification process by filter bag
The dust being attached on filter bag is more and more, increases the resistance of filter bag, causes to gradually decrease by filter bag gas flow, for dedusting
Device can work normally, it is necessary to control resistance in a certain range（140 ~ 170 millimeters of water）, must once being more than the range
It must carry out deashing to filter bag, when deashing is the compression in gas bag by each control valve unbalanced pulse valve of pulse control instrument sequence trigger switch
Air, through in Wen's pipe inspection to each corresponding filter bag, filter bag moment drastically expands, makes product be attached to filter bag table by each hole of injection tube
The dust releasing in face, then filter bag restPose, and clearly under dust fall into ash bucket, through dust removing system be discharged body, thus
Product is set to be attached to the dust on filter bag by periodically pulse jetting deashing, to make purification gas normal through guarantee dedusting system
System normal operation.
And in dust pelletizing system, every deduster is provided with the warehouse of different number according to different filter areas, Mei Gecang
