Rapid cooling device and cooling method for furnace lining

Abstract

The invention relates to a rapid cooling device and a cooling method for a furnace lining. By the device and the method, not only a steelmaking furnace lining can be rapidly cooled, but also resources are not wasted. The device comprises the furnace lining in which a heat absorption coil consisting of a plurality of circles of water-cooled coiled pipes is arranged. A water inlet of the heat absorption coil is communicated with an outlet of a water cooling recovery tower through a water inlet pipe. An inlet of the water cooling recovery tower is communicated with an outlet of the heat absorption coil through a water returning pipe. The device and the method have the advantages that: the steelmaking furnace lining can be rapidly cooled, cooling water can be recovered and recycled, water resources are saved, and an environment is protected.

Description

technical field

[0001] The invention relates to a furnace lining rapid cooling device and a cooling method which can quickly cool the steelmaking furnace lining without causing waste of resources and environmental pollution, belonging to the field of manufacturing steelmaking furnace lining cooling devices. Background technique

[0002] CN201463532U, name "embedded rapid heat conduction furnace lining furnace shell direct cooling smelting furnace", includes embedded rapid heat conduction furnace lining, cooler and water circulation device. The heat conduction block is embedded in the high temperature zone in the middle of the furnace wall along the circumference, and the embedded fast heat conduction furnace lining forms direct heat conduction with the cooler installed outside the furnace wall, and the cooler is supplied with water by the water circulation device. It is especially suitable for the transformation of traditional electric furnaces for the smelting of insoluble ...

Examples

Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 . A furnace lining rapid cooling device, which includes a furnace lining 1, the furnace lining has a built-in heat absorbing ring 2 composed of multiple turns of water-cooled coils, the water inlet of the heat absorbing ring 2 communicates with the outlet of the water cooling recovery tower 4 through a water inlet pipe 3, and the water cooling The inlet of the recovery tower 4 communicates with the outlet of the heat absorbing ring 2 through the return pipe. The bottom 5 in the water cooling recovery tower 4 is equipped with a centrifugal impeller and driven by a motor. The body of the water cooling recovery tower 4 is provided with a plurality of air guide holes 6 .

Embodiment 2

[0011] Example 2: On the basis of Example 1, a method for quickly cooling the furnace lining, when the furnace lining 1 needs to be cooled, put the heat absorbing ring 2 into the furnace lining 1 and the upper part of the heat absorbing ring 2 is higher than the furnace lining mouth, and the cooling water is recovered The cooling water in the tower 4 flows into the heat-absorbing ring 2 through the water inlet pipe, and when it flows through the heat-absorbing ring 2, it absorbs the heat in the furnace lining and then enters the cooling water recovery tower 4 through the return pipe. Driven by the motor, the water-leaving impeller will return the water that flows back to the cooling water recovery tower 4 to centrifugal atomization and cooling in the tower, and then supply the heat-absorbing ring 2 through the water inlet pipe to absorb heat again, and circulate like this until the furnace lining cools down to the required temperature .
