Description
Technical field
The utility model relates to a kind of bag-type dust collector, particularly a kind of composite bag-type pulse backblowing dust arresters that are used for steel industry blast furnace gas dry dusting technology more.
Background technology
Bag-type dust collector is widely used in the dedusting of all gases medium or solid and the gas barrier technology, in the technical field especially for blast furnace gas dry dusting.In the prior art, bag-type dust collector generally by casing, dust-removal cloth-bag, dividing plate, pulse backblowing device, dusty gas air inlet/pure qi (oxygen) body gas outlet, flue-dust retainer, unload structures such as ash and defeated ash mouth and form.Dusty gas enters casing from the dusty gas air inlet in the dust removal process, and through behind the permeation filtration, gas enters in the dust-removal cloth-bag, by collecting pipe, enters the pure qi (oxygen) body plenum chamber unit of casing, again by the output of pure qi (oxygen) body gas outlet.Pulse backblowing gas enters from the winding-up house steward, by the winding-up arm that is located at the cloth sack dust-removal cloth-bag is carried out pulse backblowing, thereby the dust blowback on the dust-removal cloth-bag is removed, and dust is by flue-dust retainer and unload grey ash conveying device and discharge casing from ash hole.According to the material of dust-removal cloth-bag, factors such as gas characteristic and gas temperature, the box body diameter of existing bag-type dust collector is generally 3.5 meters, and it is 130 millimeters that built-in cloth bag length is generally 6 meters and diameter, can establish 192 of dust-removal cloth-bags in the single casing at most.Because the restriction of the factors such as winding-up efficient of cloth bag blowback system, the effective length of this dust-removal cloth-bag can not increase.The required dust arrester casing quantity of whole dust-removal system is more, takes up an area of also greatlyyer, and cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of composite bag-type dust collector, increases the filter area of single casing, improves filter efficiency, reduces to take up an area of and investment.
Composite bag-type dust collector of the present utility model comprises casing, dust-removal cloth-bag, following ash bucket etc.; Ash bucket and ash guiding pipe are set, described casing is divided into upper box and lower box, all be equipped with dust-removal cloth-bag in upper box and the lower box; Upper and lower casing all is provided with dusty gas air inlet and pure qi (oxygen) body gas outlet; Upper spacer and lower clapboard are set, upper box and lower box are separated out upper collecting chamber and next part case respectively; Pulse cleaning system is set in the upper and lower casing wherein dust-removal cloth-bag is carried out the pulse backblowing deashing; There is air inlet communicating pipe that the dusty gas air inlet of upper box and lower box is connected at box house or outer setting; At box house or outside have the communicating pipe of giving vent to anger that the pure qi (oxygen) body gas outlet of upper box and lower box is connected.
Wherein pulse cleaning system is made up of blowback house steward and blowback arm, and the port of this blowback arm reaches dust removing cloth sack position.
Wherein the dusty gas of upper and lower casing inlet and the outlet of pure qi (oxygen) body are provided with control valve, control gas filtration speed.
The technical solution of the utility model can reach following beneficial effect: the effective filtration area that increases single casing, can make the cloth bag filter area of single casing reach 1.7 times that have sack cleaner list casing dedusting area now, thereby improved the efficiency of dust collection of single casing, reduce casing quantity, reduced the area and the cost that take.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 5, the single casing of composite bag-type dust collector is made up of upper box 13 and lower box 11, wherein upper box 13 is made up of upper collecting chamber 1, upper box gas outlet 2, upper box dividing plate 3, dust-removal cloth-bag 5, last ash bucket 6, ash guiding pipe 10, upper box air inlet 14, lower box 11 is made up of next part case 8, lower box dividing plate 9, cloth bag 5, lower box gas outlet 7, lower box air inlet 16, following ash bucket 12, by air inlet communicating pipe 15 communicating pipe 4 upper box 13 and lower box 11 being connected into an integral body with giving vent to anger.Air inlet communicating pipe places the casing outside communicating pipe with giving vent to anger.
Dusty gas enters upper box 13 and lower box 14 simultaneously by lower box air inlet 16, air inlet communicating pipe 15, upper box air inlet 14 in the dust removal process, after the dust-removal cloth-bag dust removal by filtration, be pooled to upper collecting chamber 1 and lower box 11 respectively, compile by upper box gas outlet 2, the communicating pipe 4 of giving vent to anger, lower box gas outlet 7 again and enter pure qi (oxygen) body total pipeline and discharge casing.
Adopt the pulse backblowing mode to carry out deashing to dust-removal cloth-bag in the dust removal process.Ash in the upper box 13 falls into ash bucket 6 earlier, imports ash bucket 12 down through ash guiding pipe 10, and the ash in the lower box 14 directly falls into down ash bucket 12, and the ash under upper box 13 and lower box 14 remove is discharged casing by the ash hole of this ash bucket after ash bucket 12 compiles down.
As Fig. 1, the utility model can also have another embodiment, is about to air inlet communicating pipe shown in Figure 5 15 and gives vent to anger move on in single casing all the other constant each several part invariant positions communicating pipe 4.The shape that can make single casing like this is standard more, is easy to carrying, deposits.
The utility model also has similarly other embodiment, for example air inlet communicating pipe can be placed the casing outside, and the communicating pipe of giving vent to anger places box house; And air inlet communicating pipe can be placed box house, and the communicating pipe of giving vent to anger places the casing outside, and other positions are constant.
