Abstract
The utility model provides a water supply device for cooling a single blast furnace hearth, which comprises a water pump station, a degassing tank, a filter, an air cooler, a flowmeter and a pipeline system; the tail part of a water supply main pipe communicated with a water pump station is connected with at least 3 water supply branch pipes in parallel, and the other end of each water supply branch pipe is connected to a transverse pipe of a hearth water supply ring pipe; the horizontal pipe of the furnace cylinder water draining ring pipe is connected with at least 3 water draining branch pipes, the other end of each water draining branch pipe is connected in parallel with a water draining main pipe, and the water draining main pipe is connected with a water pump station after passing through a degassing tank, a filter and an air cooler. The utility model discloses can make the furnace hearth cooling water supply amount reach more than 1.4 times of former system, not only realize that the furnace hearth supply amount is adjustable, increased blast furnace hearth cooling water yield, provide the cooling water that reduces 10-15 ℃ than furnace hearth, furnace shaft water supply system's temperature simultaneously for the furnace hearth moreover to greatly improve furnace hearth cooling effect, prolong the life of furnace hearth.
Description
Technical field
The utility model belongs to the ironmaking equipment field.Relate in particular to a kind of water supply installation that water coolant is provided for the blast furnace hearth cooling separately.
Background technology
Blast furnace longevity is the important process that blast furnace system is safeguarded.Ensure that the most effective means of blast furnace longevity are the coolings of reinforcement cooling stave, namely by increasing cooling water flow, guarantee cupola well carbon brick hot-face temperature less than 900 ℃, can effectively slow down the erosive velocity quickening that the various cause for erosion such as basic metal, molten iron, slag cause.
At present, all BF Designs all are that a pump works supplies blast furnace hearth, shaft water simultaneously, and blast furnace hearth and shaft take the mode of serial or parallel connection to supply water.The shortcoming of this way of supplying water: the one, cupola well and shaft same system supply water cause cupola well, shaft separately the water yield can't regulate.The 2nd, the thermal load of shaft is 10-20 times of cupola well, and cupola well, shaft share a waterworks, because shaft thermal load height causes water temperature high, with the water quench cupola well of comparatively high temps, is unfavorable for that cupola well cools off, and affects the blast furnace hearth life-span.
Summary of the invention
The utility model aims to provide a kind ofly can adjust the cupola well service discharge at any time, for cupola well provides the water coolant of lesser temps, thereby improves the cupola well cooling intensity, prolongs cupola well single water supply installation for the blast furnace hearth cooling in work-ing life.
For this reason, the solution taked of the utility model is:
A kind of single water supply installation for the blast furnace hearth cooling comprises that pump works, degassing vessel, strainer, air cooler, flow take into account piping system; At least 3 subfeeders with electric butterfly valve of service main afterbody parallel connection that are communicated with pump works, the other end of each subfeeder are connected on the transverse tube of cupola well feedwater endless tube; Transverse tube at cupola well draining endless tube is connected with at least 3 with the branch drain of electric butterfly valve, and each branch drain the other end is connected in parallel on the main drain, and main drain is connected with pump works after via degassing vessel, strainer and air cooler.
The beneficial effects of the utility model are:
Because for blast furnace hearth provides separately water coolant, make cupola well cooling water amount reach more than 1.4 times of original system, realized that not only the cupola well service discharge is adjustable, increased the blast furnace hearth cooling water inflow, and provide the water coolant of lesser temps for cupola well, the comparable cupola well of coolant water temperature, the shaft simultaneously coolant water temperature of waterworks reduce 10-15 ℃, thereby greatly improve the cupola well cooling performance, prolong the work-ing life of cupola well.
Description of drawings
Accompanying drawing is single water supply installation synoptic diagram for the blast furnace hearth cooling.
Among the figure: pump works 1, main drain 2, service main 3, subfeeder 4, feedwater electric butterfly valve 5, under meter 6, cupola well feedwater endless tube 7, air cooler 8, strainer 9, cupola well cooling stave water pipe 10, degassing vessel 11, draining endless tube 12, draining electric butterfly valve 13, branch drain 14.
Embodiment
The utility model list is that a cover waterworks independently is set for the water supply installation of blast furnace hearth cooling, provides water coolant for blast furnace hearth separately.
By accompanying drawing as seen, single water supply installation for the blast furnace hearth cooling mainly is comprised of pump works 1, main drain 2, service main 3, subfeeder 4, feedwater electric butterfly valve 5, under meter 6, air cooler 8, strainer 9, degassing vessel 11, draining electric butterfly valve 13, branch drain 14.
Water pump in service main 3 feed-water ends and the pump works 1 is connected, outlet tail 6 subfeeders 4 in parallel, respectively be provided with a feedwater electric butterfly valve 5 on 6 subfeeders 4, the other end of 6 subfeeders 4 is connected on the transverse tube of cupola well feedwater endless tube 7, and the water coolant in the cupola well feedwater endless tube 7 cools off by 10 pairs of cupola wells of cupola well cooling stave water pipe.Cupola well cooling stave water pipe 10 exit end connect cupola well draining endless tube 12, also be connected with 6 on the transverse tube of draining endless tube 12 with the branch drain 14 of draining electric butterfly valve 13, the water side of each branch drain 14 is connected in parallel on the main drain 2, and main drain 2 is successively via being connected with pump works 1 behind degassing vessel 11, strainer 9 and two groups of air coolers 8.
Claims (1)
1. a single water supply installation for the blast furnace hearth cooling is characterized in that, comprises that pump works, degassing vessel, strainer, air cooler, flow take into account piping system; At least 3 subfeeders with electric butterfly valve of service main afterbody parallel connection that are communicated with pump works, the other end of each subfeeder are connected on the transverse tube of cupola well feedwater endless tube; Transverse tube at cupola well draining endless tube is connected with at least 3 with the branch drain of electric butterfly valve, and each branch drain the other end is connected in parallel on the main drain, and main drain is connected with pump works by behind degassing vessel, strainer and the air cooler.
