Description

DEVICE OF WATER COOLING OF A DOMAIN FURNACE

The utility model relates to ferrous metallurgy, in particular to blast furnace water cooling devices.

A device for water cooling of a blast furnace comprising a pumping station, a pressure head conduit, a distribution manifold, a cooling tower, a burnout detection control unit for water-cooled elements 1 is known.

The disadvantage of this device is the increase in temperature of the cooled water due to the fact that part of the waste water, bypassing the tower, is mixed with the cooled water.

A blast furnace water cooling device is known, comprising a pump station connected via a pressure line through a distribution manifold to water-cooled blast furnace elements connected by pressure discharge pipes to a waste water collector that is connected to a cooling tower connected to a receiving chamber of a pump station by a water pipe; on pressure discharge pipes, a burnout detection control unit for water-cooled elements is installed, made of tapering discharge pipes and a drain funnel connected by a pressureless conduit to the receiving chamber of the pump station 2.

The disadvantage of this blast furnace cooling device is that part of the waste water, bypassing the tower, is mixed with chilled water in the receiving chamber of the pump station, which increases its temperature.

The technical result, to which the proposal is directed, is to reduce the temperature of the water entering the pumping station for cooling the blast furnace.

To achieve this result, a blast furnace water cooling device comprising a pump station connected via a pressure pipe through a distribution manifold to blast furnace water-cooling elements and connected pressure pipes to a waste water collector, a cooling tower connected to a chilled water pipe to a pump station receiving chamber, a control unit burnout detection of water-cooled elements made of tapering outlet pipes connected to molecular recovery line, and a drain funnel, provided with a blower jet, which nozzle is connected with the collecting conduit of the collector waste water suction inlet of the jet compressor is connected to the drain water conduit with a funnel, a discharge pipe connected to the water conduit with a cooling tower.

The figure shows a schematic diagram of a device for water cooling of a blast furnace.

The blast furnace water cooling device comprises a pump station 1 connected by a pressure pipe 2 through a distribution manifold 3 with water-cooled elements 4 of the blast furnace and connected by pressure pipes 5 having check valves 6, with a waste water collector 7 in which the water is under pressure from the pump station 1, water conduit 8, jet supercharger 9, cooling tower 10, control unit for detecting burnouts of water-cooled elements, including tapering outlet pipes Ku-12, water conduits 13, 14 and 15.

The jet supercharger 9 includes a nozzle 16. connected by a water conduit 8 to a waste water collector 7, a suction pipe 17. connected by a water conduit 13 to a drain funnel 12, and a discharge pipe 18 connected by a water conduit 15 to a cooling tower 10.

A water cooling device for a blast furnace operates as follows.

Cold water from the pump station 1 through the pressure pipe 2 is supplied to the distribution manifold 3, and then it enters the water-cooled elements 4 of the blast furnace, passing through the cavity of the water-cooled elements 4 under the pressure of the pump station 1, the heated water is supplied by pressure pipes 5 with check valves b prefabricated waste water collector 7, from which through conduit B to the nozzle 16 of the jet supercharger 9. At the same time, the waste water is discharged from each pressure discharge pipe 5 to the tapered discharge pipes 11 of the block for controlling obfuscation of burns of water-cooled elements and then to the drain funnel 12 of this block, and then to the suction pipe 17 of the jet supercharger 9. Then, from the discharge pipe 18, all waste water from the blast furnace is fed to the cooling tower 10 via a water conduit 15. Chilled water by gravity along the conduit 14 enters the receiving chamber of the pumping station 1.

The application of this proposal allows all the waste water supplied to cool the blast furnace to be fed to the tower using existing external networks and to vary the ejection coefficient over a wide range. As a result, the temperature of the water entering the pumping station decreases.
