4: whirlwind flabellum；Because the helical structure of flabellum produces centrifugal force when making flue gas enter, thus the big grit in dusty gas is separated.
5: ash collection slot；The grit separated from flue gas is made to collect and be got rid of by soot cleaning valve.
6；Soot cleaning valve；Dust in ash collection slot is got rid of, seals simultaneously and prevent flue gas excessive.
7: support arm；Support whole device, fix with ground land used bolt.
8: discharging opening seals lid；When changing dedusting granule, used granule uses seal cap sealing after discharging from discharging opening.
9: agitator arm；Intermittent stirring, for stirring the particulate matter in filter cylinder, it is prevented that particulate matter adhesion.
10: charging aperture seals lid；When changing dedusting granule, when being added from charging aperture by new granule after old particulate removal, then use seal cap sealing.
11: filter cylinder；It is used for filling filtration particulate matter, makes flue gas be filtered fully, then pass through discharge duct and discharge (in a preferred version, drainage screen is installed at exhaustor road junction).
12: admission line: input pending flue gas.
Mineral hot furnace mechanical type pre-dedusting device of the present utility model has the advantage that

Detailed description of the invention
Below in conjunction with accompanying drawing, mineral hot furnace mechanical type pre-dedusting device of the present utility model is described in detail.Should be understood that detailed description below and the explanation carried out in conjunction with accompanying drawing are merely for the purpose of this utility model is described, but be not limited to scope of the present utility model.
First, flue gas is discharged from mineral hot furnace, enters this device by admission line 12.Flue gas first passes through the whirlwind flabellum 4 in admission line, enters the space between shell 3 and the filter cylinder 11 of device.Because the effect of admission line whirlwind flabellum 4 becomes whirlwind, centrifugal force can be utilized to be separated by grit from flue gas, makes the bulky grain thing in flue gas strike on the inwall of shell 3 and be deposited in ash collection slot 5 when flue gas enters, thus realizing first time dedusting.
Then, short grained grit is also remained through the flue gas of first time dedusting.Now not separated tiny grit enters in filter cylinder 11 along with flue gas, and owing to there being filtration particulate matter in filter cylinder 11, when air-flow flows through particulate matter filtering layer, grit is delayed in filtering layer, it is achieved thereby that second time dedusting.In one embodiment, filtration particulate matter is coke grain.
Finally, due to discharge duct 1 stretches into filter cylinder 11 inside, the flue gas through twice dedusting enters next device by discharge duct 1.In one embodiment, the pipeline opening of discharge duct 1 also to install drainage screen, and reason is to prevent particulate matter from being taken out of filter cylinder by flue gas by discharge duct.
When this device works, it is possible to intermittence and lentamente rotation agitator arm 9, it is therefore an objective to prevent particulate matter from boning, keep particulate matter loose.
When dedusting granule need to be changed, discharging opening is sealed lid 8 and opens, used particulate matter is discharged, discharging opening is sealed lid 8 good seals；Again charging aperture is sealed lid 10 to open, virgin material is added in filter cylinder, charging aperture is sealed lid 10 good seals.Used particulate matter can be recycled, processes and recycles.
Pre-dedusting device of the prior art is transformed by this utility model, cyclone dust removal and granule dedusting is combined, it is achieved high-effective dust-removing, makes flue gas can reach higher dedusting standard and energy-conserving and environment-protective more when pre-dedusting.
Although, above illustrate by generality and this utility model has been done detailed description by specific embodiment, but on this utility model basis, it is possible to it is made some modifications or improvements, and this will be apparent to those skilled in the art.Therefore, not necessarily depart from these modifications or improvements on the basis of this utility model spirit, belong to the scope that this utility model claims.
