Second step is after power failure, and staff observes thermometer the 31, first Pressure gauge 37 and the second Pressure gauge 38;Work as temperature When table 31 shows the temperature of water leg 24 higher than 75 degree, in water leg 24, existing part water is vaporized;Now open the 3rd valve 33, the water vapour in water leg 24 is passed through water supply tank 22 by the 6th pipeline 25, makes to be between water supply tank 22 and water leg 24 Identical pressure;Staff confirms to locate between water supply tank 22 and water leg 24 by the first Pressure gauge 37 and the second Pressure gauge 38 Opening the second valve 28 after identical pressure, the water in water supply tank 22 flows into water leg 24, and hydraulic pressure in water supply tank 22 Under effect, the most heated water in water leg 24 flows to heat exchange box 3 by the first pipeline 6, finally flows into tank 2;
If the most first opening the 3rd valve 33 and directly opening the second valve 28, the water in water leg 24 may be caused because of pressure liter High (water contacted with electric arc furnace 1 can vaporize because not flowing, and causes pressure to raise) and refluence, to water supply tank 22, so will Cause the water in water supply tank 22 cannot flow downwardly into water leg 24, until the water in water leg 24 dryouies, steam pressure is less than and mends The hydraulic pressure of water tank 22, thus cause safety problem and steam contamination problem in the process.
In the middle of the carrying out of second step, staff persistently carries out following two operation:
1. observe thermometer 31, after thermometer 31 shows that the water temperature of water leg 24 is less than 50 degree, close the second valve 28;Water presss from both sides Water temperature in set 24 is gone up after more than 75 degree, reopens the second valve 28;This operation is prevented from water supply tank 22 Water too fast inflow water leg 24, to such an extent as to do not fully absorb the heat energy in electric arc furnace 1 and just spilt out by the first pipeline 6.This behaviour The meaning made is when having a power failure that making full use of water in water supply tank 22 absorbs the ability of heat energy.
2. the liquid level in water supply tank 22 is observed by the first transparent tube 29, when in water supply tank 22, liquid level is high less than water supply tank 22 Degree 1/3 time, open the 3rd valve 33 and diffusion valve 30, make water in elevated tank 21 inject water supply tank by the 8th pipeline 32 22, water supply tank 22 fills the water in water or water supply tank 22 elevated tank 21 when using up, and closes the 3rd valve 33 and diffusion valve 30.
In first step, while starting the second circulating pump 19 and the first circulating pump 10, start blower fan 18 thus accelerate The heat radiation of indirect cooling water.
(not having a power failure) when normally working, the carrying out practically situation of first step is: starts the first circulating pump 10 and second and follows Ring pump 19, the water in tank 2 is sent in the water leg 24 of electric arc furnace 1, is used for cooling down electric arc furnace 1 by the second circulating pump 19;From The coolant-temperature gage flowed out in water leg 24 is higher, as directly discharge will produce substantial amounts of steam, pollutes working environment, makes plant area's wall Impaired because of long-term moist.In the present invention, the water flowed out in water leg 24 sends into heat exchange box 3, by the inner tube 4 of heat exchange box 3 Time, with pipe outside cooling water generation heat exchange.The setting of heat exchange disc 5 can be greatly improved heat exchange efficiency, and because heat exchange The existence in hole 12 and the flowing of the most too much impact cooling water.After heat exchange, from the temperature of the water that electric arc furnace 1 water leg 24 flows out It is greatly reduced, injects the bottom of tank 2 finally by the second pipeline 7.If the second pipeline 7 is not passed through the end of tank 2 Portion, but opening is at tank 2 ullage, then still can flow out a small amount of steam 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 steam can be avoided completely to permeate into the phenomenon in air. Second circulating pump 19 makes this part water circulate between electric arc furnace 1 water leg 24, heat exchange box 3 and tank 2, the coldest But electric arc furnace 1.
Water bottom cooling tower is sent into heat exchange box 3 by the first circulating pump 10, and this part water flow direction in heat exchange box 3 is with interior In pipe 4 water flow to contrast, form countercurrent flow, in cooling inner tube 4, the efficiency of water is higher.This part water is through the 3rd pipeline 88 flow out, and in the effect of hydraulic pressure downstream to the top of cooling tower, flow to ground floor 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.Water overflow to after bottom the cooler bin 13 of cooling tower, quilt First circulating pump 10 is extracted out again, carries out next round recuperated cycle.
Above example is only in order to illustrative not limiting technical scheme, although with reference to above-described embodiment to this Bright be described in detail, it will be understood by those within the art that: still the present invention can be modified or etc. With replacing, any modification or partial replacement without departing from the spirit and scope of the present invention, it all should contain the power in the present invention In the middle of profit claimed range.
