Description
Technical field
The present invention relates to a kind of filter, especially a kind of vacuum filter, belongs to filter technology field.
Background technology
Bag filter is a kind of equipment being widely used in the numerous areas such as environmental protection, purification.Traditional bag filter is primarily of formations such as filtration system, pulse jet system, compressed air system, ash discharge systems.During work, solid particulate matter in the bag-like filter element trapping dusty gas utilizing fibrous braid to make, reaches the effect of dedusting.
When the high-temperature dusty gas adopting the contour fire grate of existing sack cleaner process steel mill to go out, filter bag is easy to be heated and burns out.Adopt first cooling to refilter, cleaner will be made to become huge, and the bulky grain dust of temperature-fall period sedimentation is difficult to get rid of.
Application number be 201220318437.6 Chinese patent application disclose a kind of vacuum filter, the cylindrical shell grills comprise filter housings, be arranged at air inlet pipe on filter cylinder upper top cover between two parties, be fixed on filter bag support under filter cylinder upper top cover between two parties, this support is upper end, being welded into by steel bar; Be set with the filter bag be fixed on filter bag support.A kind of vacuum filter of the present invention, for the airflow filtering device of titanium sponge distillation vacuum pump set front end, can improve the corrosion-resistant and wear resistance of vacuum pump set, avoid air-flow at a middle or low price thing or magnesium powder, magnesium chloride powder enter vacuum system, pollute pump oil.But there is following problem in this type of filter use procedure: 1) owing to not having bulky grain capturing structure, when therefore filtering the high-temperature gas of containing metal particle, easy spontaneous combustion forms Mars and makes filter element burn out inefficacy; 2) owing to not having uniform stream structure, therefore unavoidable dusty gas is uneven and cause Partial filtration component failure too fast, causes system pressure drop rapid, and result makes that frequency of maintenance is too high, production cost strengthens; 3) lack cooling behave, easily shorten the service life of filter element because filtering gas temperature is too high.
Summary of the invention
The object of the invention is to: the shortcoming existed for above-mentioned prior art, propose one can not only filtering high temperature ash-laden gas time body good dedusting effect, and the vacuum filter that compact conformation, life of bag filter are long, thus meet the processing demands of blast furnace waste gas.
In order to reach above object, vacuum filter of the present invention comprises vertical tube shape filter housings, described housing upper vacuumizes when having work and leads to the clean chamber of filter of gas outlet, bottom, described filter clean chamber is the filter chamber separated by filter bag supporting plate, one group of sack is settled to be supported on the tubulose filter bag of filter bag supporting plate support in described filter chamber, spout is equipped with respectively facing to the pulse spraying equipment of each filter bag in the clean chamber of described filter, it is the deflection cone of convergent bottom described filter chamber, its improvements are: described housing extends the direct tube section containing deflection cone down, described direct tube section has the control of dust cone of tangential admission mouth and bottom convergent, the bottom of described control of dust cone is ash hole able to turn on or off, the bottom of described deflection cone has the end mouth stretching into control of dust cone, in described deflection cone, there is maze device, described maze device is made up of one group of metal chin spoiler of central shaft radial radiation and one group of metal baffle upper plate.
During work, high-temperature dusty gas enters control of dust cone from tangential admission mouth, forms the whirlwind of backspin, drops to ash hole place after making oarse-grained dust clash into control of dust cone wall under the action of the centrifugal.The negative pressure of vortex center makes air-flow enter the end mouth of deflection cone, through maze device.This device not only plays the effect of uniform stream, and gas dissipates heat is lowered the temperature, and the clean gas afterwards through filter bag enters filter clean chamber output.
It is that the angular position of described chin spoiler and baffle upper plate staggers that the present invention further improves, and can make air-flow full and uniformization like this.
The present invention further improves, and side, described control of dust cone bottom is provided with the broken arch mouth of input pulse air-flow.Desirable ash-removal effect can be ensured like this.

Detailed description of the invention
Embodiment one
The vacuum filter of the present embodiment as shown in Figures 1 to 4, comprise the vertical tube shape filter housings 1 of circular section, housing 1 top have with vacuum generating equipment together with vacuum flange mouth 1-14, vacuumize when top has work and lead to the clean chamber 1-1 of filter of gas outlet 1-4.Filtering 1-1 bottom, clean chamber is settle one group of sack to be supported on the tubulose filter bag 2 of filter bag supporting plate support in the filter chamber 1-3 separated by filter bag supporting plate 1-2, filter chamber 1-3.Filter clean chamber 1-1 and spout is housed respectively facing to the pulse spraying equipment 3 of each filter bag.Be the deflection cone 1-5 of convergent bottom filter chamber 1-3.Housing 1 extends the direct tube section 1-6 containing deflection cone 1-5 down, and direct tube section 1-6 has the control of dust cone 1-7 of tangential admission mouth 1-8 and bottom convergent.The bottom of control of dust cone 1-7 is the dust-collecting cylinder 1-11 with ash hole 1-9 able to turn on or off.The bottom of deflection cone 1-5 has the end mouth 1-10 stretching into control of dust cone 1-7.
In deflection cone 1-5, there is maze device, this maze device as shown in Figs. 5 to 7, by vertical central shaft 5-1 radial radiation and uniform 12 metal chin spoiler 5-3 and 12 metal baffle upper plate 5-2 form.Leave axially spaced-apart 5-4 between chin spoiler 5-3 and baffle upper plate 5-2, angular position staggers each other.After high temperature air enters, metal chin spoiler 5-3 and metal baffle upper plate 5-2 can make air-flow full and uniformization, has good radiating and cooling effect simultaneously.
In addition, bottom control of dust cone 1-7, side is provided with the broken arch mouth 1-12 of input pulse air-flow.Like this, can input pulse air when needed, the dust on tube wall is fully deposited.As shown in Figure 8, ash hole 1-9 is equipped with and hingedly goes out tepetate 9-1 in side, dust-collecting cylinder 1-11 lower end, go out lever arm outer end that tepetate 9-1 extends and hinged piston rod end of boring the ash discharge cylinder 9-2 of 1-7 lower end at control of dust is hinged, therefore dust can be worked as when reaching level-sensing device 1-13, tepetate 9-1 is opened out in control, timely deashing.Positiver sealing during in order to ensure out that tepetate 9-1 closes, dust-collecting cylinder 1-11 away from the side going out tepetate 9-1 hinged place also hinged have closed time clamp out the locking bail 9-3 of dirt lid 9-1, the tailpiece of the piston rod of the compressor arm outer end that this locking bail 9-3 extends and the hinged locking cylinder 9-3 at dust-collecting cylinder 1-11 is hinged, therefore, after can closing going out tepetate 9-1, compressing out tepetate and making its positiver sealing.
During work, the filter of the present embodiment makes cyclone dust removal and filtering dust collecting organically combine, therefore compact conformation, good purification, and experiment proves, also tool has the following advantages:
1) vacuum state runs, and can avoid high temperature active metal generation naked light, stopping filter bag and to be heated the phenomenon burnt out by controlling oxygen content.
2) air flow method evenly and adopt the copper heat dissipation metal that thermal conductivity is good, therefore can significant prolongation life of bag filter.
3) deflection cone in the process changing airflow direction, can be collected bulky grain dust, alleviates the burden of filter bag.
4) arch breaking apparatus employing gas shakes and replaces machinery to shake, and ash-removal effect is more obvious.
5) deashing device good sealing effect, easy to operate.
