Description
Technical field
The present invention relates to gas dispersion particle filter field.
Background technology
Sack cleaner is a kind of dry type dust filtration device.It is applied to trap tiny, dry, non-fiber dust.Filter bag
Using weaving filter cloth or nonwoven felt into, dusty gas is filtered using the filtration of fabric, when containing
After dust and gas body enters sack cleaner, particle is big, heavy dust, because 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.
After filtrate uses a period of time, due to effects such as sieving, collision, delay, diffusion, electrostatic, filter bag surface is gathered
One layer of dust, this layer of dust are referred to as bonding layer, and in motion process after this, bonding layer relies on into the main filtration layer of filtrate
The effect of bonding layer, the larger filtrate of mesh can also obtain higher filter efficiency.As dust is in the accumulation of filter material surface, dedusting
The efficiency and resistance of device all accordingly increase, and when the pressure differential of filtrate both sides is very big, some can be attached on filtrate
In the tiny grit extruding past, decline dust collector efficiency.In addition, the resistance of deduster it is too high can make dust pelletizing system air quantity it is notable
Decline.Therefore, accumulation of ash to after certain thickness, timely deashing on filtrate.Bonding layer can not be destroyed during deashing, in order to avoid efficiency
Decline.
Deashing generally use contact for sack cleaner device filter material surface and contactless two kinds in the prior art
Mode：Contact is directly to be struck off the dust of filter material surface using instruments such as scraper plate, scrapers, but during striking off, is struck off
Instrument will apply pressure to dust, and dust is pressed into the filter opening of filtrate, block on the filter opening and bonding layer of filtrate between dust
The gap of formation, reduces filter efficiency；And contactless deashing then will using modes such as mechanical oscillation, acoustic vibration, winds
Dust is removed, but this mode must integrally remove the dust on filtrate together, destroy bonding layer.
The content of the invention
The invention is intended to provide a kind of bag-type dust collector, to be purified to dusty gas, and retain in deashing
Bonding layer, ensure purification efficiency.
Bag-type dust collector in this programme, including support, dust cleaning case, filter mechanism and deashing mechanism, dust cleaning case installation
On support, the top of dust cleaning case is provided with air inlet；Filter mechanism includes filter bag and filter bag frame, and filter bag is arranged on filter bag frame,
Filter bag keeps tensioning, and filter bag frame is arranged on the bottom of dust cleaning case, and the dust cleaning case of filter bag frame bottom is provided with air outlet；The deashing
Mechanism includes support frame and shower nozzle, and the top of filter bag frame is rotatably connected in the middle part of support frame, and shower nozzle is slided the two of support frame
On end, shower nozzle is parallel with filter bag frame.
The technical principle of this programme and have the beneficial effect that：Dusty gas enters in dust cleaning case from air inlet, due to air outlet
The bottom of filter bag frame is arranged on, therefore dusty gas has to pass through the filter mechanism on filter bag frame.Filter bag is in dusty gas
Dust is filtered, and one layer of bonding layer is gathered on filter bag surface.With increasing for Chalk-dust filtering, the thickness of bonding layer is more and more thicker, filter
The filter efficiency of bag reduces.Filter bag keeps tensioning to be beneficial to make the filter opening on filter bag to keep opening, while also causes filter bag flattening, makes
Dust on filter bag ensures that thickness is uniform.Now, the shower nozzle on slide holder, the distance between adjusting shower nozzle and filter bag, makes
The distance between shower nozzle axis and filter bag outer surface are equal to the thickness of required bonding layer, and pressure fluid, shower nozzle guiding are passed through to shower nozzle
Pressure fluid is sprayed, and because shower nozzle is parallel with filter bag frame, pressure fluid is washed away on filter bag surface beyond bonding layer caliper portion
Dust, so as to reach the effect for retaining bonding layer, ensureing purification efficiency.
Further, the filter bag frame is tapered, and support frame as described above is in the shape of the letter V, and the middle part of support frame is ogival, support frame
Both sides be side arm, the shower nozzle is slidably connected on side arm.Shower nozzle when being slided on side arm relative to filter bag frame parallel translation,
Shower nozzle obliquely downward, sprays liquid beneficial to shower nozzle and washes away dust, the liquid also sprayed beneficial to shower nozzle washes away dust, and protects all the time
The thickness for demonstrate,proving the bonding layer retained is uniform.
Further, in addition to feed tube and flexible pipe, feed tube run through filter bag frame below filter bag frame, and support frame as described above rotates
It is connected at the top of feed tube, support frame has been internally formed cavity, and feed tube connects with cavity, soft pipe connection cavity and the spray
Head.Pressure fluid is passed through from feed tube, pressure fluid enters in the cavity of support frame, and enters shower nozzle by flexible pipe
In so that shower nozzle can also spray pressure fluid when being slided on support frame, and propulsive thrust when also being sprayed using pressure fluid pushes away
Dynamic support frame rotates automatically.
Further, the air inlet of the dust cleaning case is provided with filter plate.Fall the impurity of larger particles degree using filter plates, keep away
Exempt from impurity to enter blocking in dust cleaning case or damage filter bag.
Further, the filter bag frame bottom is provided with base, and base is cylindrical, and the outer wall of base is provided with external screw thread,
The screwed hole being engaged with base is provided with the bottom of dust cleaning case.Connected by the external screw thread on base outer wall and screwed hole screw thread
Connect, both easy disassembly filter bag frame, there is the sealing that can ensure between base and dust cleaning case.
Further, the size of the filter bag frame bottom is less than the size of the dust cleaning case bottom, and dust cleaning case bottom is provided with row
Liquid pipe, between filter bag frame and dust cleaning case, discharging tube is communicated to outside dust cleaning case discharging tube, and discharging tube is provided with valve.Wash away
The liquid of dust and the dust being washed will accumulate in the bottom of dust cleaning case, and discharging tube is opened up in bottom, be easy to liquid and
Outside dust discharge dust cleaning case；And when liquid and dust need not be discharged, then close valve.
