Abstract
The utility model discloses an air flow distribution device of a blast-furnace gas bag-type dust collector. A guide grating is obliquely arranged at a position, which is just opposite to a flue gas inlet, in a box and is inclined from the flue gas inlet to the other opposite side. According to the air flow distribution device, the dust collection efficiency of the dust collector is improved, the service life of the cloth bag is prolonged, air flow scouring is alleviated, and the equipment repair and maintenance cost is further reduced.
Description
Technical field
The utility model relates to a kind of blast furnace gas cloth bag dedusting device, refers in particular to a kind of blast furnace gas cloth bag dedusting device airflow distribution device.
Background technology
Blast furnace gas cloth bag dedusting device generally comprises ash bucket, casing, cloth bag and blowing device; Ash bucket is arranged on casing below, and cloth bag is arranged in casing, is positioned at ash bucket top; Blowing device is arranged on casing top, be positioned at cloth bag top, and blowing device inflatable mouth is just to cloth bag, meanwhile, generally in ash bucket upper end, smoke inlet is set.
Blast furnace raw gas is entered in blast furnace gas cloth bag dedusting device casing by smoke inlet via raw coke oven gas main pipeline, particle enters ash bucket compared with large dust free settling, the dust that particle is less follows air-flow to rise, and is filtered by cloth bag, makes coal gas reach the object of purification.When the dust on cloth bag surface runs up to when a certain amount of, blowing device is opened inflatable mouth and is utilized Compressed Gas that dust is blown off.
The airflow distribution state entering in blast furnace gas cloth bag dedusting device casing directly has influence on the service life of dedusting of blast furnace gas efficiency, cloth bag and the maintenance maintenance cost of equipment.In prior art, blast furnace gas cloth bag dedusting device generally arranges airflow uniform distribution device together between cloth bag bottom and smoke inlet.Described airflow uniform distribution device is generally the water conservancy diversion grid across casing truncation surface, or for being arranged on the deflector at smoke inlet place.
The defect of described airflow uniform distribution device is: water conservancy diversion grid or deflector, make to occur compared with maelstrom phenomenon near the air-flow of box body wall, and this region gas velocity is larger, cause cloth bag to rock, between cloth bag and box body wall, cloth bag and cloth bag, very easily there is friction and make cloth bag breakage, and then declined to the service life of cloth bag, and directly affecting dust-collecting efficiency, maintenance cost is higher.
Utility model content
The purpose of this utility model is to provide a kind of dust-collecting efficiency high, the blast furnace gas cloth bag dedusting device airflow distribution device that long service life and maintenance cost are low.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of blast furnace gas cloth bag dedusting device airflow distribution device is just installed water conservancy diversion grid to smoke inlet inclined position in casing, and water conservancy diversion grid is tilted toward relative opposite side from smoke inlet.
Further, water conservancy diversion grid is made up of the water conservancy diversion bent plate longitudinally arranging.
Further, water conservancy diversion bent plate is curved, and the recess of arc water conservancy diversion bent plate is unanimously towards smoke inlet.
Further, in casing upper end, inspection manhole is set, and on water conservancy diversion grid, support member is set.
Further, water conservancy diversion grid is in the form of annular discs.
Adopt after such scheme, the utility model is just installed water conservancy diversion grid to smoke inlet inclined position in casing, and water conservancy diversion grid is tilted toward relative opposite side from smoke inlet.Raw coke oven gas air-flow is evenly distributed on casing cross section, and then stable enters into dust-filtering district, reduce the air velocity of raw coke oven gas simultaneously, reduce the eddy flow of cloth bag district raw coke oven gas and wash away.Not only improve the dust-collecting efficiency of deduster, also improved the service life of cloth bag and reduced airflow scouring, and then having reduced maintenance of equipment maintenance cost.

Fig. 2 is the cutaway view of Figure 1A-A direction;
Fig. 3 is the utility model water conservancy diversion bent plate structural representation.
Label declaration
Casing 1 smoke inlet 11
Inspection manhole 12
Water conservancy diversion grid 2 water conservancy diversion bent plates 21
Support member 22 recesses 211.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
Consult shown in Fig. 1 to Fig. 3, a kind of blast furnace gas cloth bag dedusting device airflow distribution device that the utility model discloses is just installed water conservancy diversion grid 2 to smoke inlet 11 inclined position in casing 1, and water conservancy diversion grid 2 is tilted toward relative opposite side from smoke inlet 11.
In the present embodiment, water conservancy diversion grid 2 is in the form of annular discs, is made up of the water conservancy diversion bent plate 21 longitudinally arranging.
Water conservancy diversion bent plate 21 is curved, and the recess 211 of arc water conservancy diversion bent plate 21 is unanimously towards smoke inlet 11, and as shown in Figure 2, water conservancy diversion bent plate 21 is preferably and is uniformly distributed, and makes coal gas air-flow velocity evenly by water conservancy diversion bent plate 21, enters dust-filtering district.Meanwhile, coal gas air-flow is by after water conservancy diversion bent plate 21, and its flow velocity slows down, and then reduces the eddy flow of cloth bag district raw coke oven gas and wash away.
In casing 1 upper end, inspection manhole 12 is set, and support member 22 is set on water conservancy diversion grid 2.Maintainer can enter casing 1 from inspection manhole 12, cloth bag is checked, and can step down on support member 22.
The utility model is installed water conservancy diversion grid 2 in casing 1 medium dip, raw coke oven gas air-flow is evenly distributed on casing 1 cross section by water conservancy diversion bent plate 21, and then stable enter into dust-filtering district, and reduce the air velocity of raw coke oven gas simultaneously, reduce the eddy flow of cloth bag district raw coke oven gas and wash away.Therefore, not only improved the dust-collecting efficiency of deduster, also improved the service life of cloth bag and reduced airflow scouring, and then having reduced maintenance of equipment maintenance cost.
The foregoing is only an embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
