Description
Technical field
This utility model relates to technical field of environment protection equipment, is specially one point and blows ash-cleaning type dust arrester.
Background technology
Cleaner unit equipment, refers to that the equipment that dust is separated from flue gas is cleaner unit or cleaner.Remove now
Dirt device category is more, predominantly: (1) mechanical force cleaner includes gravitational dust collection equipment, inertial dust collection equipment, centrifugal dust-removing
Equipment etc..(2) washing type cleaner includes water-bath type cleaner, foam type cleaner, Venturi tube cleaner, water
Membrane type cleaner etc..(3) filtering type cleaner includes (4) electrostatic precipitation such as bag-type dust equipment and granular layer cleaner
Equipment.(5) magnetic dust removal equipment.
Wherein, what the comparison in industry was many is sack cleaner.Bag-type dusting utilizes filter bag to carry out dust removal by filtration
Technology.Operationally, gas by outside filter bag to internal, dust is at filter bag outer surface.Dusty gas is from the air intake current-sharing of cleaner unit
Pipe enters each locellus ash bucket, and under the water conservancy diversion of ash bucket guiding device, oarse-grained dust is separated, and falls directly into ash bucket, and
Relatively fine dust adsorbs on the outer surface of filter bag evenly into middle part casing, and clean gas enters upper box through filter bag,
And enter air through each Off-line valve and exhaust duct.Along with the carrying out of filtration operating mode, the dust on filter bag is cumulative, when equipment hinders
When power reaches Resistance Value (being usually set to 1500Pa) limited, dust disposing device set by differential pressure setpoint or deashing time
After definite value is automatically switched off a Room Off-line valve, open electric control pulse valve by setup program, carry out blowing-out winding-up, utilize compressed air wink
Between winding-up make pressure pcl in filter bag increase, the dust on filter bag carries out shaking off (even if viscous fine dust also can more thoroughly deashing) extremely
In ash bucket, ash exhauster discharge.
But, existing dust arrester structure comparison is single, and all of filter bag is installed in same casing, if needed
Reverse gas cleaning to be carried out, then need whole equipment blowing-out, and then recycling compressed air realizes entering filter bags all in casing
Row moment jets.This just have impact on the continuous work of complete machine, not only reduces the efficiency of work, and the poor efficiency of deashing,
Leverage the effect of the follow-up dedusting of device.
