Abstract
The utility model relates to a gravity dust removal device of a blast furnace. The gravity dust removal device comprises an ash deposition hopper I and an ash deposition hopper II, wherein the two ash deposition hoppers are connected with each other through a valve I; the bottom of the ash deposition hopper II is connected with a humidifier through a valve II; a plurality of vibrators are uniformly distributed on the side surfaces of the ash deposition hopper I and the ash deposition hopper II; the valve I and the valve II are ash discharging ball valves; cleaning openings are formed in the side surfaces of the bottoms of the ash deposition hopper I and the ash deposition hopper II. The gravity dust removal device of the blast furnace can discharge ash continuously; normal production cannot be affected, and production of secondary dust is avoided; furthermore, the on-site working environment is improved; the ash cleaning amount is reduced, and the labor intensity is alleviated. As the ash can be discharged in time, excessive agglomeration of ash can be prevented, and the safety coefficient is improved.
Description
Technical field
The utility model relates to a kind of blast furnace gravitational dust collecting device.
Background technology
It is a continuously smelting process that blast furnace is produced, in smelting process, produce a large amount of raw gas, and raw gas gathers and contains a large amount of dust, can not directly discharge, must be through purifying treatment ability second stage employ, fly-ash separator is to process blast furnace raw gas visual plant, raw gas enters after gravitational precipitator, because flow velocity reduces, dust in raw gas rely on self gravity fall pile up, through unloading valve, regularly discharge, otherwise, while piling up a large amount of dusts in gravitational precipitator, will affect dust removing effects.
Current gravitational precipitator generally only has an ash bucket, and owing to producing, whole system, in state with pressure, can not frequently be unloaded ash, and dust easily lumps in ash bucket, should not discharge, and have the danger of gas leak while unloading ash.
Utility model content
In order to unload, ash is convenient, safety, efficient, and the utility model provides a kind of blast furnace gravitational dust collecting device.
The utility model is by the following technical solutions:
Blast furnace gravitational dust collecting device, comprises ash bucket I and ash bucket II, and described two ash buckets connect by valve I, and described ash bucket II bottom is connected with humidifier by valve II.
The uniform some vibrators in side of described ash bucket I and ash bucket II.
Described valve I and valve II are Unloading ball valve.
The bottom sides of described ash bucket I and ash bucket II has clean-up port.
Using method of the present utility model is: open valve I, valve-off II, open if desired vibrator, dust in ash bucket I falls into ash bucket II and all falls into after ash bucket II when the dust of ash bucket I, valve-off I, opens humidifier, opens valve II and unloads ash, after unloading ash and completing, repeat above operation.
The utility model can unload ash continuously, does not affect normal production, has avoided the generation of secondary dust, has improved on-the-spot Working environment, has reduced deashing amount, has reduced labour intensity.Owing to unloading ash in time, can prevent the excessive caking of dust, improved safety coefficient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
1, ash bucket I; 2, valve I; 3, ash bucket II; 4, valve II; 5, humidifier; 6, clean-up port.
Embodiment
As shown in Figure 1, ash bucket I 1 is connected by valve I 2 with ash bucket II 3, and ash bucket II 3 bottoms are connected with humidifier by valve II 4.Two uniform some vibrators of lateral area ash bucket.
Described valve I 2 and valve II 4 are Unloading ball valve.
The bottom sides of described ash bucket I 1 and ash bucket II 3 has clean-up port 6.
Using method of the present utility model is: open valve I 2, valve-off II 4, open if desired vibrator, the dust in ash bucket I 1 falls into ash bucket II 3, closes blowback pulse valve, dust in ash bucket I 1 all falls into after ash bucket II 3, valve-off I 2, opens humidifier, opens valve II 4 and unloads ash, after unloading ash and completing, repeat above operation.
Although above-mentioned, by reference to the accompanying drawings embodiment of the present utility model is described; but the not restriction to the utility model protection domain; described those skilled in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still within protection domain of the present utility model.
