Description
Technical field
The utility model is related to dust removal field, more particularly to a kind of automatically cleaning dust settling pocket.
Background technology
The dusty gas that Low-Pressure Pulse Bag Filter is mainly used for the industries such as metallurgy, electric power, building materials purifies, and dust settling pocket
It is the core component of deduster, is directly related to the dust removing effects of deduster.The dust settling pocket being commonly used is mainly by bag body
With bag cage form, wherein bag body is usually the cylindrical shape cloth bag (both ends equal diameter) that one end open one end is not open, according to containing
The characteristic and working condition of dust and gas body, this dust settling pocket service life is about in 1.5-2.
Pulsed jet cloth filter is made of the part such as ash bucket, upper box, middle case, lower box, and upper, middle and lower babinet is point
Cell structure.When work, dusty gas enters ash bucket by air inlet duct, and thick grit falls directly into hopper bottom, and dustshot turns with air-flow
It rolls in being upwardly into, lower box, dust product is attached to filter bag outer surface, and filtered gas enters upper box to net gas concetrated pipe-
Exhausting duct drains into air through exhaust blower.Deashing process is the net gas outlet conduits for being initially switched off the room, and the cloth bag of the room is made to be in
Airless by state (locellus blowing-out deashing).It is then turned on pulse valve and carries out pulse jetting deashing with compressed air, cut off
Valve closing time is enough to ensure that the dust settling removed from filter bag after injection to ash bucket, avoids dust and is being detached from filter bag table
The phenomenon that behind face again with the attached collection of air-flow to adjacent filter bag surface, keep filter bag ash removal thorough, and by program controller PLC instrument to exhaust
Valve, pulse valve and unloading valve etc. carry out Automatic Control.
Application No. is 201020549287.0 utility model patents to disclose a kind of dedusting for bag-type dust collecting equipment
Bag, can overcome the halfway defect of prior art deashing.To achieve the above object, the technical solution adopted in the utility model
A kind of dust settling pocket, including marsupial body, this bag of one end closure of body, one end open, which is characterized in that the bag body be taper or
Person's taper type bag body, and the open end diameter of the bag body is more than sealing end diameter.Use the dedusting of above-mentioned technical proposal
Bag, fully can make the dust being attached on bag body fall off, and in jetting deashing, can keep blast pass by gravity
Intensity is held essentially constant, and reaches that the blast pass dynamic pressure of bag in vivo everywhere is much the same, and then improves the deashing effect of deduster
Fruit reduces dedusting cost.
But it still by the way of pulse dust removal, structure is complex, and the auxiliary of electric-control system is needed to realize.Electricity
Control system is influenced to be susceptible to failure by micronic dust, and complicated cost is higher.
