Relatively low temperature（Water leg cooled furnace wall is set）, therefore electric arc furnaces 1 is traditional energy consumption rich and influential family, is often saved needed for one section of production
The time wanted, big energy can be saved.
In first step is running, when there is power failure phenomenon, second circulation pump 19 and first circulation pump 10 stop
Only, second step is now carried out；
Second step is after power failure, and staff observes thermometer 31, first pressure table 37 and second pressure gauge 38；When
When thermometer 31 shows that the temperature of water leg 24 is higher than 75 degree, existing part water is vaporized in water leg 24；Now open the 3rd
Valve 33, the water vapour in water leg 24 are passed through water supply tank 22 by the 6th pipeline 25, made between water supply tank 22 and water leg 24
In identical pressure；Staff by first pressure table 37 and second pressure gauge 38 confirm water supply tank 22 and water leg 24 it
Between be in identical pressure after open the second valve 28, the water in water supply tank 22 flows into water leg 24, and the water in water supply tank 22
In the presence of pressure, the heated water in water leg 24 flows to heat exchange box 3 by the first pipeline 6, finally flows into tank 2；
If first not opening the 3rd valve 33 and directly opening the second valve 28, the water in water leg 24 may be caused because of pressure
Power raises（The water being in contact with electric arc furnaces 1 can vaporize because not flowing, and cause pressure rise）And flow backwards to water supply tank 22, so
The water in water supply tank 22 will be caused can not to flow downwardly into water leg 24, until the water in water leg 24 dryouies, steam pressure is low
In the hydraulic pressure of water supply tank 22, so as to cause safety problem and steam contamination problem in the process.
Among the progress of second step, staff persistently carries out following two operations：
1. observing thermometer 31, after thermometer 31 shows that the water temperature of water leg 24 is less than 50 degree, the second valve 28 is closed；
Water temperature in water leg 24 is gone up to after more than 75 degree, reopens the second valve 28；This operation can prevent water supply tank 22
Interior water is too fast to flow into water leg 24, so that the heat energy not fully absorbed in electric arc furnaces 1 is just spilt out by the first pipeline 6.
The meaning of this operation is to make full use of the ability of water absorption heat energy in water supply tank 22 when having a power failure.
2. the liquid level in water supply tank 22 is observed by the first transparent pipe 29, when liquid level is high less than water supply tank 22 in water supply tank 22
Degree 1/3 when, open the 3rd valve 33 and diffusion valve 30, the water in elevated tank 21 is passed through the 8th pipeline 32 and inject water supply tank
22, when the water that water supply tank 22 fills in water or the elevated tank 21 of water supply tank 22 is used up, close the 3rd valve 33 and diffusion valve 30.
In first step, while second circulation pump 19 and first circulation pump 10 is started, start blower fan 18 so as to accelerate
The radiating of indirect cooling water.
During normal work（Do not have a power failure）, the carrying out practically situation of first step is：Start first circulation pump 10 and second to follow
Ring pump 19, the water in tank 2 is sent into the water leg 24 of electric arc furnaces 1 by second circulation pump 19, for cooling down electric arc furnaces 1；From
The coolant-temperature gage of outflow is higher in water leg 24, and such as directly discharge will produce substantial amounts of steam, pollutes working environment, makes plant area's wall
It is damaged because long-term moist.In the present invention, heat exchange box 3 is sent into from the water of the interior outflow of water leg 24, passes through the inner tube 4 of heat exchange box 3
When, heat exchange occurs with the cooling water outside pipe.The setting of heat exchange disc 5 can greatly improve heat exchange efficiency, and because heat exchange
The presence in hole 12 is without the excessive flowing for influenceing cooling water.After heat exchange, from the temperature of the water of the water leg 24 of electric arc furnaces 1 outflow
It is greatly reduced, the bottom of tank 2 is injected finally by the second pipeline 7.If the second pipeline 7 is not passed through the bottom of tank 2
Portion, but be open in the ullage of tank 2, then a small amount of steam still can be flowed out from the second pipeline 7, environment is caused on a small quantity
Steam contamination；Second pipeline 7 is not passed through the bottom of tank 2, then the phenomenon that steam can be avoided to permeate into air completely.
Second circulation pump 19 makes this part water be circulated between the water leg 24 of electric arc furnaces 1, heat exchange box 3 and tank 2, constantly cold
But electric arc furnaces 1.
First circulation pump 10 will cool down tower bottom water be sent into heat exchange box 3, this flow direction of part water in heat exchange box 3 with it is interior
The reclaimed water of pipe 4 flows to contrast, forms countercurrent flow, and the efficiency for cooling down the reclaimed water of inner tube 4 is higher.This part water is through the 3rd pipeline
88 outflows, the top of cooling tower is flow in the presence of hydraulic pressure, flows to first layer seal cup 17, and step by step to underflow stream.Overflowing
During stream, blower fan 18 is dried, and accelerates the heat exchange of water and air.Behind water overflow to the bottom of cooler bin 13 of cooling tower, quilt
First circulation pump 10 is extracted out again, carries out next round recuperated cycle.
Above example is only to illustrative and not limiting technical scheme, although with reference to above-described embodiment to this hair
It is bright to be described in detail, it will be understood by those within the art that：Still the present invention can be modified or be waited
With replacing, any modification or partial replacement without departing from the spirit and scope of the present invention, it all should cover the power in the present invention
Among sharp claimed range.
