Description

A kind of pulse off-line type bag dust collector

Technical field

The utility model belongs to deduster technical field, is specifically related to a kind of pulse off-line type bag dust collector.

Background technique

A large amount of dusty gas can be generated in industry in fusion process, generally by easy bag dust collector to flue gas into Row purified treatment；When bag dust collector works online, under the action of exhaust fan, dust is attracted to outside filter bag after entering ash bucket Surface makes dust fall on hopper bottom by injection tube intermittently blowing, is discharged through unloading valve；Dust-laden higher for dust content Gas, the filter bag inside bag dust collector are blocked quickly, need frequent shutdown to handle, operating cost is caused to increase, and and its It is unfavorable for the dedusting of dust atmosphere, causes a large amount of dusty gas that cannot be handled in time and spills into atmospheric environment, makes At environmental pollution.

Summary of the invention

In view of this, being stopped the purpose of this utility model is to provide a kind of pulse off-line type bag dust collector by locellus Wind pulse jetting deashing, the continual a large amount of dusty gas of processing, to avoid spilling into atmospheric environment due to dusty gas In caused by problem of environmental pollution.

In order to achieve the above object, a kind of pulse off-line type bag dust collector of the utility model, including ash bucket, the net gas of son Room, conveyance conduit, public air-purifying chamber, air-introduced machine, public foul smell room and injection tube, there are two the ash buckets and controls side by side, often A ash bucket upper half is internally provided with filter bag, and each ash bucket upper end is provided with the sub- air-purifying chamber being connected to filter bag, every height Air-purifying chamber is connected to by a conveyance conduit with public air-purifying chamber, and the offline of control conveyance conduit on-off is provided on conveyance conduit Valve, public air-purifying chamber are connected to the air inlet that air-introduced machine has, and injection tube passes through what sub- air-purifying chamber and face filter bag upper end had It is open, pulse valve is provided in injection tube, public foul smell room has foul smell import, connects inside public foul smell room and ash bucket lower half Logical, hopper bottom has ash hole, is provided with unloading valve on ash hole.

Further, the sub- air-purifying chamber and ash bucket lower half forward extend out the ash bucket upper half, sub- air-purifying chamber and ash bucket it Between form preposition groove, the conveyance conduit, public air-purifying chamber and public foul smell room are both placed in preposition inside grooves, delivery pipe Road, public air-purifying chamber, public foul smell room are successively arranged from top to bottom.

It further, further include bracket, two ash buckets are fixed on bracket.

Further, the public air-purifying chamber is left right angle trigonometry cylinder, and public foul smell room is right right angle trigonometry cylinder, left straight triangle The inclined surface of cylinder and the inclined surface of right straight triangle cylinder are overlapped, and left right angle trigonometry cylinder and left straight triangle cylinder are spliced into a rectangular cylinder, Foul smell import is arranged in left right angle trigonometry cylinder left end, and the air inlet that air-introduced machine has is connected to right right angle trigonometry cylinder right end.

It further, further include Mars trap, what Mars trap had exports and foul smell inlet communication without Mars.

The utility model has the beneficial effects that:

1. work efficiency is high for a kind of pulse off-line type bag dust collector of the utility model, and two ash buckets share one Public air-purifying chamber is conducive to energy saving；Using two ash buckets, one of ash bucket is used for for purifying dusty gas, together When, reversed jetting deashing is carried out to the filter bag in another ash bucket using injection tube, thus the continual a large amount of dust-laden of processing Gas；Since two ash buckets share a public air-purifying chamber, and public air-purifying chamber is connected to the air inlet that air-introduced machine has, because This, it is only necessary to air-introduced machine can be to providing induced air negative-pressure inside two ash buckets.

2. a kind of pulse off-line type bag dust collector compact overall structure of the utility model is conducive to reduce whole body Product；Due to forming preposition groove between sub- air-purifying chamber and ash bucket, conveyance conduit, public air-purifying chamber and public foul smell room are both placed in Preposition inside grooves, therefore, conveyance conduit, public air-purifying chamber, public foul smell room and ash bucket can be abutted mutually, so that The utility model entirety compact overall structure.

3. a kind of pulse off-line type bag dust collector of the utility model is conducive to further reduce whole volume；Due to public affairs Air-purifying chamber is left right angle trigonometry cylinder altogether, and public foul smell room is right right angle trigonometry cylinder, the inclined surface of left straight triangle cylinder and right straight triangle The inclined surface of cylinder is overlapped, and left right angle trigonometry cylinder and left straight triangle cylinder are spliced into a rectangular cylinder so that public air-purifying chamber with it is public The distance between foul smell room reaches most short, so that the utility model entirety overall structure is more compact.

4. a kind of pulse off-line type bag dust collector of the utility model has preprocessing function；Mars trap is for collecting Larger particles in dusty gas, while the Mars in dusty gas can be stopped to enter inside ash bucket.
