Description
Technical field
The utility model relates to pulse dust removal equipment technical field, specially a kind of pulsed jet cloth filter.
Background technique
Pulsed jet cloth filter is made of the part such as ash bucket, upper box, lower box, and upper and lower cabinet is chamber structure.Work
When, dusty gas enters ash bucket by air inlet duct, and thick grit falls directly into hopper bottom, and dustshot is upwardly into down with air-flow turnover
Cabinet, dust product are attached to filter bag outer surface, and filtered gas enters upper box to exhausting duct, drains into atmosphere through exhaust blower.Clearly
Grey process is the net gas outlet conduits for being initially switched off the room, and so that the cloth bag of the room is in the state that airless passes through, (locellus blowing-out is clear
Ash).Be then turned on pulse valve and carry out pulse jetting deashing with compressed air, cutting valve closing time be enough to ensure that after blowing from
The dust settling removed on filter bag avoids dust after being detached from filter bag surface again with the attached collection of air-flow to adjacent filter bag table to ash bucket
The phenomenon that face, keeps filter bag ash removal thorough, and full-automatic to the carry out such as exhaust valve, pulse valve and unloading valve by program controller PLC instrument
Control.
Breakage once occurs for the filter bag of traditional pulsed jet cloth filter, will allow the filtered gas with flue dust into
Enter upper box to be discharged from exhaust passage, and then causes to pollute environment.
Utility model content
Breakage once occurs for the filter bag of above-mentioned pulsed jet cloth filter, will allow the filtered gas with flue dust
Into upper box to be discharged from exhaust passage, and then lead to the problem of polluting environment, the utility model provides a kind of pulse cloth
Bag dust collector will not cause flue dust to be discharged with the gas that purification is completed even if it is when filter bag damage after.
Its technical solution is such that a kind of pulsed jet cloth filter comprising ash bucket, lower box, filter bag, card, on
Cabinet, the lower box are connected with air inlet duct, are located at the air inlet duct in the lower box and are also equipped with wind deflector, it is described on
Deashing component is installed, the upper box is connected with exhaust passage, and the exhaust passage is connect with exhaust blower, and feature exists in cabinet
In: the exhaust passage and the upper box junction are equipped with filtering layer, and the exhaust passage and the upper box are also equipped with first
Differential pressure pickup, first differential pressure pickup are electricly connected with exhaust blower and alarm.
It is further characterized by:
The lower box and the upper box are equipped with the second differential pressure pickup, second differential pressure pickup with it is described
Deashing component electricly connects；
The wind deflector includes vertical portion and the horizontal component for being installed vertically on vertical portion top, the horizontal part
Ventilation hole is provided on point.
After with such a structure, even if filter bag damage, flue dust also can be stopped to avoid by the filtering layer at air outlet
It is discharged, when the flue dust accumulation on filtering layer causes the pressure difference between upper box and exhaust passage to reach setting value to a certain extent
When, the first differential pressure pickup may turn on alarm equipment alarm and closing exhaust fan makes deduster stop working, to allow operation
Personnel replace remaining flue dust in damaged filter bag and cleaning upper box in time；In addition, gas through filter bag and filtering layer two
Secondary filtering, effect are more preferable.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
A kind of pulsed jet cloth filter as shown in Figure 1 comprising ash bucket 1, lower box 2, filter bag 3, card 4, upper box
5,1 lower part of ash bucket is equipped with discharge valve 15, and lower box 2 is connected with air inlet duct 6, is located at air inlet duct 6 in lower box 2 and is also equipped with
Wind deflector, wind deflector include vertical portion 7 and the horizontal component 8 for being installed vertically on 7 top of vertical portion, on horizontal component 8
It is provided with ventilation hole, deashing component 9 is installed in upper box 5, upper box 5 is connected with exhaust passage 10, exhaust passage 10 and exhaust blower 11
Connection, exhaust passage 10 and 5 junction of upper box are equipped with filtering layer 12, and exhaust passage 10 and upper box 5 are also equipped with the first pressure difference biography
Sensor 13, the first differential pressure pickup 13 are electricly connected with exhaust blower 11 and alarm (being not drawn into figure), lower box 2 and on
Cabinet 5 is equipped with the second differential pressure pickup 14, and the second differential pressure pickup 14 is electricly connected with deashing component 9.
Gas with flue dust enters in lower box 2 from air inlet duct 6, and a part of flue dust is due to gravity and wind deflector
Vertical portion 7 blocking fall into lower part ash bucket 1, gas is flowed up along wind deflector vertical portion 7, due to have ventilation hole
Horizontal component 8 blocking, and a part of flue dust can be made to fall into the ash bucket of lower part, then pass through the filtering of filter bag 3, in entrance
Cabinet 5, then exhaust passage 10 is entered by filtering layer 12, deduster is discharged.
And if breakage occurs for wherein one or more filter bags 3, the breakage that a part of flue dust passes through filter bag 3 enters
In cabinet 5, filtering layer 12 can stop the lower flue dust that will enter exhaust passage 10 at this time, and the material of filtering layer 12 can be with filter bag
3 select identical material.
When filter bag 3 since the flue dust of accumulation excessively causes pressure difference rising in lower box 2 and upper box 5 to reach setting value
When, the second differential pressure pickup 14 controls the starting of deashing component 9 and carries out deashing processing to filter bag 3, and the degree of automation is good；When filtering layer 12
On soot build-up when upper box 5 and the pressure difference of exhaust passage 10 excessively being caused to reach setting value, the first differential pressure pickup 13 is opened
Alarm equipment alarm is opened, and controlling exhaust blower 11 makes it stop working.
More playscript with stage directions utility models can be connected in parallel on same air inlet duct 6, if wherein one stop working, it is other still
It can work on, to not interfere with the progress of dust removal process.
More than, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is not limited to
In this, any people for being familiar with the technology is in the technical scope disclosed by the utility model, and any changes or substitutions that can be easily thought of,
It should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with claim
Subject to protection scope.
