Abstract
The utility model discloses a dust collecting device of a cinder valve of an RH vacuum furnace, which comprises a dust transporting vehicle, a sealing dust collecting cover and a cloth bag dust removing device, wherein the dust transporting vehicle is arranged under the cinder valve at an opening of a condenser of an RH vacuum room, and the sealing dust collecting cover contains the dust removing valve and is communicated with the dust transporting vehicle. The sealing dust collecting cover is communicated with the cloth bag dust removing device through a pipeline; and the cloth bag dust removing device is communicated with a dust removing fan. The dust collecting device can collect the dust which is unloaded from the dust collecting cover, is outwards overflowed, and can be freely diffused to the air, thereby reducing the dust emission concentration of the region of the cinder valve and the post dust concentration, as well as the environment pollution and the dust damage to post workers.
Description
Technical field
The utility model relates to airborne dust and administers technical field, particularly a kind of RH vacuum drying oven unloading valve dust arrester installation.
Background technology
At present, the RH vacuum drying oven of steel-making subsidiary factory produces dust in the course of the work, described dust is collected via RH vacuum chamber condenser, and the unloading valve of the opening by being positioned at described RH vacuum chamber condenser unloads ash and handles, at last, the defeated grey car that is positioned at described unloading valve below is transported away the dust that falls because of gravity that described unloading valve unloads, and finally finishes the dust subsequent treatment to the RH vacuum drying oven.
Yet, described unloading valve in unloading grey processing procedure, in the dust that unloads except a part because of gravity falls into defeated grey car, some to around excessive and freely be diffused in the air.The described dust in air that is diffused into is being shrouded the unloading valve region, cause this regional dust emission concentration on average more than 300mg/Nm3, the post dust concentration is on average more than 17mg/Nm3, two concentration are well beyond the national environmental standard requirement, not only caused than serious environmental and polluted, and the post worker is subjected to comparatively serious flue dust injury.
Therefore, be necessary to provide a kind of RH vacuum drying oven unloading valve dust arrester installation to collect and be diffused into dust in air, and then the solution unloading valve unloads the dust pollution problem that ash is produced.
Summary of the invention
The purpose of this utility model provides a kind of RH vacuum drying oven unloading valve dust arrester installation, can collect that unloading valve unloads to around excessive and freely be diffused into dust in air, and then reduce the dust emission concentration and the post dust concentration of unloading valve region, thereby reduce environmental pollution, reduce post worker's flue dust injury.
For achieving the above object, the utility model provides a kind of RH vacuum drying oven unloading valve dust arrester installation, comprises a defeated grey car that is arranged on the unloading valve below of RH vacuum chamber condenser opening part.Described RH vacuum drying oven unloading valve dust arrester installation also comprises the sealing dust collection cover and the sack cleaner that contain described unloading valve and be communicated with described defeated grey car, described sealing dust collection cover is communicated with described sack cleaner by pipeline, and described sack cleaner is communicated with dedusting fan.
In an embodiment of the present utility model, described pipeline comprises dust collection pipe that is communicated with described sealing dust collection cover and the back cleaning shaft that is communicated with described sack cleaner, and described dust collection pipe links to each other by an electric butterfly valve with described back cleaning shaft.
Preferably, described sealing dust collection cover is provided with manhole door.
Equally preferably, described dedusting fan is communicated with chimney.
Compared with prior art, the sealing dust collection cover of the utility model RH vacuum drying oven unloading valve dust arrester installation collect that described unloading valve unloads to around excessive and freely be diffused into dust in air.Described dedusting fan provides wind-force, makes dust in the described sealing dust collection cover via the described sack cleaner of described pipeline flow-direction.Described sack cleaner is collected described dust.Therefore, the dust arrester installation of the utility model RH vacuum drying oven can reduce the dust emission concentration and the post dust concentration of unloading valve region, reduces environmental pollution, reduces post worker's flue dust injury.
By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.
Description of drawings
Fig. 1 is a kind of main TV structure schematic diagram of RH vacuum drying oven unloading valve dust arrester installation;
Fig. 2 is the main sectional structure schematic diagram of RH vacuum drying oven unloading valve dust arrester installation shown in Figure 1, and the dust when having showed its work simultaneously flows to.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As Fig. 1-2, described RH vacuum drying oven unloading valve dust arrester installation comprises the sealing dust collection cover 130 and the sack cleaner 190 that are arranged on defeated grey car 150, the described unloading valve 220 of containing of unloading valve 220 belows of RH vacuum chamber condenser 120 opening parts and are communicated with described defeated grey car 150.Described sealing dust collection cover 130 is communicated with described sack cleaner 190 by pipeline.Described sack cleaner 190 is communicated with dedusting fan 200.Described dedusting fan 200 is communicated with chimney 210.
With reference to figure 2, when needs unload the ash processing, start described unloading valve 220 and dedusting fan 200, the dust that the RH vacuum drying oven 110 that described RH vacuum chamber condenser 120 is collected produces unloads (as shown by arrow A) by described unloading valve 220, the dust that falls because of gravity that described unloading valve 220 unloads is transported away (as shown by arrow B) by described defeated grey car 150, described unloading valve 220 unload to around excessive and freely be diffused into dust in air collect the sealing dust collection cover 130 in, provide wind-force after described dedusting fan 200 starts, make dust in the described sealing dust collection cover 130 via the described sack cleaner 190 of described pipeline flow-direction (as shown by arrow C).The described sack cleaner 190 final described dusts of collection also leach the air that is mixed in the described dust, and described dedusting fan 200 is discharged (as shown by arrow D) with described air by described chimney 210.When not needing to unload the ash processing, described unloading valve 220 and dedusting fan 200 are all closed.
As seen from the above, present embodiment RH vacuum drying oven unloading valve dust arrester installation can be seen the dust that falls because of gravity off by defeated grey car 150 on the one hand, can collect the dust that freely spreads by sealing dust collection cover 130, dedusting fan 200, pipeline and sack cleaner 190 on the other hand, thereby reduce the dust emission concentration and the post dust concentration of unloading valve 220 regions, reduce environmental pollution, reduce post worker's flue dust injury.Through test, the exhaust gas dust concentration of emission of unloading valve 220 regions drops to 30mg/Nm
