Description

A kind of bag filter for aqueous dust
Technical field
The utility model belongs to the technical field of dust processing, and in particular to a kind of bag-type dust for aqueous dust Device.
Background technology
Bag filter is a kind of dry type dust filtration device.It is suitable for trapping tiny, dry, non-fiber dust.Filter bag Using weaving filter cloth or nonwoven felt into, aqueous dust is filtered using the filtration of fabric, when containing After pigment dirt enters sack cleaner, particle is big, heavy dust, since the effect of gravity settles down, falls into ash bucket, contains There is the gas of relatively fine dust when passing through filtrate, dust is purified gas by detention.
Filter bag in use for some time, as dust is in the accumulation of filter material surface, efficiency and resistance all phases of deduster The increase answered, when the pressure differential of filtrate both sides is very big, the tiny grit that some can be attached on filtrate extrudes the past, makes Dust collector efficiency declines.In addition, the excessive air quantity that can make dust pelletizing system of the resistance of deduster is remarkably decreased.Therefore, deduster After resistance reaches certain numerical value, timely deashing.
Filter bag carries out jetting deashing using compressed air, and deashing mechanism is by gas bag, injection tube and electromagnetic pulse control valve etc. Composition.Filter bag outlet top is often arranged in filter chamber and is equipped with an injection tube, face filter bag center is equipped with injection on the downside of injection tube Mouthful, it is equipped with a pulse valve in every injection tube and is communicated with compressed air gas bag.During deashing, solenoid valve opens pulse valve, Compressed air is through spraying by dust disposing device(Differential pressure or timing, control manually)Electromagnetic pulse injection, pressure are opened by setup program Contracting gas is several times as much as injection tolerance in order through each pulse valve with the time of extremely short rush through the nozzle induction in injection tube Air enters filter bag, forms air wave, filter bag is produced expansion and impact vibration drastically by sack to bottom, causes very strong Deashing acts on, and shakes off the dust on filter bag.
But above purge mode, for the larger dust of water content, effect is unsatisfactory.Because using pocket type When deduster carries out dedusting to aqueous dust, that not only adheres on filter bag has dust particles, some moisture, when dust When water content is larger, filter bag water content can also increase therewith, and during use pulse backblowing deashing, air quantity is smaller, blow-time pole It is short, it is difficult to which the dust on filter bag is blown off, it is more difficult to filter bag is dried up, due to filter bag only in the dry state, competence exertion Good filtration, therefore, when handling aqueous dust, seldom uses sack cleaner, but remove using other Dirt equipment, or processing is dried to aqueous dust, sack cleaner is used after removing moisture therein, which adds The input of equipment and improve processing cost.
