Description
Technical field
The present invention relates to a kind of systems of keeping off the rain for blast furnace sack cleaner.Belong to dedusting technology field.
Background technique
Tapping hole, skimming tool when the flue dust that cast house mainly generates includes normal tapping, trough, roughing runner, swing
The flue dust of the generations such as chute.Cast house smoke and dust treatment is most important, such as not effectively administers, and not only pollutes cast house operating environment
Endangering operator's health, (the free state SiO2 especially in flue dust can generate greatly harm, tapping to human respiratory
In the flue dust of field about 3.67%) SiO2 containing free state, will also pollute the atmospheric environment of BF Area.
It now, is mostly pulse dust collector for the sack cleaner of blast furnace, when pulse bag type dust collector works normally, dust-laden
Gas enters ash bucket by air inlet, and due to the rapid expansion of gas volume, the thicker grit of a part is by inertia or natural subsidence
Etc. reasons fall into ash bucket, remaining most of grit ascends into pocket with air-flow, and after sock filtration, grit is trapped in filter bag
Outside, purified gas is discharged into atmosphere by entering upper box inside filter bag, then by valve plate hole, exhaust outlet, removes to reach
The purpose of dirt.With the continuous progress of filtering, dust remover resistance is also risen with it, when resistance reaches certain value, dust-removing control
Device issues deashing order, will promote valve plate first and close, and cut off filtered airflow；Then, dust-removing control device is sent out to impulse electromagnetic valve
Signal out, as pulse valve is sent into the high pressure inverted draft for being used as deashing in bag, the rapid bulging of filter bag, and generate and tremble strongly
It is dynamic, cause the dust on the outside of filter bag to be shaken off, achievees the purpose that deashing.
Since pulse dust collector is exposed in external environment, when raining, rainwater pours impulse electromagnetic valve, and to will affect pulse clear
Ash is gone on smoothly, and existing pulse dust collector carries out waterproof using rain-proof shelter, but the structure of rain-proof shelter is simple, with deduster
Top cannot agree with, so that rainwater cannot be blocked completely, simultaneously because the influence of wind, rain-proof shelter cannot stop rainwater to pour completely
Impulse electromagnetic valve, therefore also need further rain-proof measure.
