Description
Technical field
The present invention provides a kind of blast furnace gas dust collectors to unload dirt device, is related to iron and steel metallurgical industry blast furnace, more particularly to
Blast furnace dedusting field.
Background technology
The raw coke oven gas generated in iron and steel metallurgical industry blast furnace smelting process, dustiness is higher, to pass through a rough dedusting
Facility is dusted, the ash-discharging device of dust removal installation originally, and only there are one DN350 ball valves, connects disc type soot cleaning valve, disk below
Be gray moving machine below formula soot cleaning valve, be humidifier below gray moving machine because dedusting ash back warp often carry blast furnace down-comer and
Deduster bulkhead washes away the foreign matters such as the brick to get off and spray paint caking, has impeller inside gray moving machine originally, passes through impeller
It rotates to control dreg discharge amount, because shell distance of the length of impeller away from gray moving machine is close, is blocked once thering is a foreign matter to come in
Impeller, if impeller continues to rotate, it is possible to outer wall top be leaked, can not be used, if opening by DN350 ball valves above
Degree control foreign matter, ball valve easily cause damage during switch, it is possible to create the leakage of coal gas causes environment gas concentration liter
Height jeopardizes worker's personal safety, to handle and just necessarily require blast furnace staying that can just be replaced, that is, causes gas leak again
Increase production cost.
Invention content
In order to solve problem above, the present invention provides a kind of blast furnace gas dust collectors to unload dirt device.
Technical scheme is as follows：A kind of blast furnace gas dust collector unloads dirt device, including the first ball being sequentially connected in series
Valve, disc type soot cleaning valve and humidifier, first ball valve are connect by pipeline with dump skip, first ball valve and disc type deashing
It is provided with the second ball valve between valve, third ball valve is installed below the disc type soot cleaning valve, the third ball valve and humidifier
Ash inlet connects.
Technical solution of the present invention further includes：First ball valve is identical as the specification of the second ball valve.Second ball valve can rise
To the effect of double containment, ensure the normal operation of equipment.
Technical solution of the present invention further includes：The third ball valve is smaller than the diameter of the first ball valve and the second ball valve.
Technical solution of the present invention further includes：The third ball valve is apart from 1~1.5m of operating platform.This position is more suitable for constructing
Personnel operate.
Technical solution of the present invention further includes：The dump skip, which is connected with to meet an urgent need by bypass pipe, unloads dirt device, avoids unloading dirt
Device breaks down, and such as situations such as disc type soot cleaning valve is seriously worn, poorly sealed, leads to be forced damping down to influence normal production to live
Dynamic situation occurs.
Technical solution of the present invention further includes：The emergent dirt device that unloads includes the first emergent ball valve and the second emergent ball valve.
Beneficial effects of the present invention are：The present invention by adding the second ball valve between the first ball valve and disc type soot cleaning valve,
To play the role of double containment, ensure the normal operation of equipment.And existing gray moving machine is replaced with into third ball valve, make third ball
Valve can replace gray moving machine to control dreg discharge amount, and solving can influence to unload dirt device normal use when foreign matter is discharged from dump skip
Problem, avoids that outer wall is impaired and gas leakage equivalent risk, and the case where avoid blast furnace staying, reduces and is produced into
This.The configuration of the present invention is simple, manufacturing cost are low simultaneously, easy to spread, have good practicability and vast market prospect.
Description of the drawings
Fig. 1 is dust-extraction unit structural representation Fig. 1 of the present invention；
Fig. 2 is dust-extraction unit structural representation Fig. 2 of the present invention.
Wherein, the 1, first ball valve, the 2, second ball valve, 3, disc type soot cleaning valve, 4, third ball valve, 5, ash inlet, 6, humidification
Device, 7, bypass pipe, 8, emergent unload dirt device, the 81, first emergent ball valve, the 82, second emergent ball valve.
Specific implementation mode
Below in conjunction with drawings and examples, the invention will be described further.
Embodiment 1：A kind of blast furnace gas dust collector unloads dirt device, including the first ball valve 1, the disc type soot cleaning valve being sequentially connected in series
3 and humidifier 6, first ball valve 1 connect with dump skip by pipeline, set between first ball valve 1 and disc type soot cleaning valve 3
It is equipped with the second ball valve 2,3 lower section of the disc type soot cleaning valve is equipped with third ball valve 4, and the third ball valve 4 and humidifier 6 are into ash
Mouth 5 connects.
First ball valve 1 is identical as the specification of the second ball valve 2, is DN350 ball valves.4 to the first ball of third ball valve
The diameter of valve 1 and the second ball valve 2 is small, is DN200 ball valves.The third ball valve 4 apart from 1~1.5m of operating platform, preferably 1.2m,
So that construction personnel operates.
Embodiment 2：On the basis of embodiment 1, the dump skip, which is connected with to meet an urgent need by bypass pipe 7, unloads dirt device 8, keeps away
Exempt to unload the failure of dirt device, such as disc type soot cleaning valve 3 because being seriously worn, it is poorly sealed situations such as, cause to be forced damping down to influence just
Normal production is movable to be happened.
The emergent dirt device that unloads includes the first emergent ball valve 81 and the second emergent ball valve 82.
When unloading dirt device and breaking down, the first ball valve 1 and the second ball valve 2 are closed, opens the first emergent ball valve 81 and the
Two emergent ball valves 82 work as Failure elimination, open the first ball valve 1 and the second ball valve 2, close the first emergent ball valve 81 and second
Emergent ball valve 82.
The present invention between the first ball valve 1 and disc type soot cleaning valve 3 by adding the second ball valve 2, to play the work of double containment
With ensureing the normal operation of equipment.And existing gray moving machine is replaced with into third ball valve 4, so that third ball valve 4 is replaced gray moving
Machine controls dreg discharge amount, solves the problems, such as to influence to unload dirt device normal use when foreign matter is discharged from dump skip, avoids outer
Wall is impaired and gas leakage equivalent risk, and the case where avoid blast furnace staying, reduces production cost.Present invention knot simultaneously
Structure is simple, manufacturing cost is low, easy to spread, has good practicability and vast market prospect.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, all at this
Done all any modification, equivalent and improvement etc., should be included in protection scope of the present invention within the spirit and principle of invention
Within.
