Background technology
In the work of blast furnace, need distribute its heat that in running, produces, guarantee the safe operation of equipment and the normal performance of performance.Mode with water-cooled is carried out good heat dissipation effect to equipment, but the present cooling device that uses, cooling water circulates and enters the object that is cooled and need the water pump power to drive, consume a large amount of electric energy first, second water circulating pump must be high temperature resistant pump, as easy as rolling off a log damage, use cost height, in case water circulating pump damages, and also easily causes potential safety hazard; The size of three quantity of circulating water influences the stable of the interior temperature of blast furnace stove.Therefore, the cooling problem that how to solve blast furnace becomes urgent problem in the industry.
On April 2nd, 2008 Chinese utility model Granted publication CN 201043863Y, disclose " a kind of furnace of calcium carbide closed circulating water cooling device " and comprised water source, supply-water pump, major circulatory system and warning system, wherein major circulatory system system is made up of water tank, major cycle water pump, the device that is cooled, heat exchanger, cooling tower, water tank and be cooled and also be provided with a spare circulating pump between the device, this complex structure still needs high temperature resistant water circulating pump.
The utility model content
At the deficiencies in the prior art, technical problem to be solved in the utility model is to propose a kind of unpowered self-circulating water cooling device that is used for blast furnace, and this device is simpler than prior art, with low cost, safety, long service life, can better stablize temperature in the stove, cut down the consumption of energy.
The utility model specific implementation is such:
A kind of unpowered self-circulating water cooling device that is used for blast furnace mainly is made of the water jacket coil pipe group on water tank, the blast furnace furnace wall; Have feed pipe and back-steam water pipe to be connected between water tank and the water jacket coil pipe group, the internal diameter of back-steam water pipe is greater than the internal diameter of feed pipe; And the lowest part of water tank bottom is higher than the highest point of water jacket coil pipe group; Feed pipe is drawn from the bottom of water tank, and high temperature pipe closer valve is installed on feed pipe; Also be connected with automatic control water replanishing device and water level meter on the water tank, make the interior water level of water tank be lower than the outlet of back-steam water pipe; Water jacket coil pipe component lower water jacket on the described blast furnace furnace wall, middle water jacket and upper water sleeve are connected with outer water pipe for three layers successively.
As further optimization, the moisturizing end of described automatic control water replanishing device connects water softening treatment plant.
As further optimization, described high temperature pipe closer valve has two parallel connections.
As further optimization, water level alarm system and ion concentration warning system are arranged on the described water tank.
As further optimization, the bottom of water tank is provided with the discharging valve of changing recirculated water.
As further optimization, residual heat using device is equipped with in the exit position of described back-steam water pipe.
As further optimization, the water vapour condensate recovery system is housed in the outlet of described back-steam water pipe.
Above-mentioned automatic control water replanishing device, water level alarm system and ion concentration warning system are the conventional equipments of known technology, can purchase from dynamo-electric market; As positive safe electrical apparatus factory, the product of the sky and water 213 electrical apparatus factories.
Above-mentioned water vapour condensate recovery system also is the conventional equipment of known technology, in this way serpentine condenser equipment.
Above-mentioned residual heat using device can be conventional steam engine generator; It also can be the heating heat-exchange device of central air-conditioning; Or even life hot water facility.
During work, water softening treatment plant is delivered in moisturizing, and water laggardly goes in the water tank to become the cooling water that is equipped with circulation cooling usefulness through softening the processing.Feed pipe is delivered to water jacket coil pipe group by water tank through high temperature pipe closer valve with cooling water it is cooled off.Cooling water successively carries out heat exchange from water jacket coil pipe group and temperature constantly raises, and causes cooling water volumetric expansion density to diminish to do ascending motion, and when temperature was higher, the part water vapor formed carbonated drink and mixes bubble, and one one up string more aggravates the current ascending motion; Carbonated drink is mixed bubble and high-temperature cooling water along back-steam water pipe foldback recovery tank, becomes recirculated cooling water after the cooling of water vapour condensate recovery system in water tank, lowers the temperature naturally once more through water tank, thereby has guaranteed the temperature of recirculated cooling water.Be provided with water level alarm system and ion concentration warning system in the water tank, set down in limited time when water level reaches, water level alarm system can give the alarm, and controls control water replanishing device amount of makeup water automatically automatically.The ion concentration warning system is mainly monitored Ca
2+, Mg
2+Ion concentration is worked as Ca
2+, Mg
2+When ion concentration reached capping, the ion concentration warning system can give the alarm, and operator's water softening treatment plant of only need fetching boiling water softens processing, treats Ca
2+, Mg
2+Ion concentration reaches to set and stops softening the processing down in limited time, enters water tank then and proceeds hydronic said process.
When recirculated cooling water needs to change through repeatedly circulating, can open the discharging valve of water tank bottom water is emitted.
The water that the utility model will enter before the circulatory system softens earlier, prevents the fouling obstruction and the corrosion of pipeline, makes the lengthening in service life of equipment.Adopt automatic alarm system control water level and Ca
2+, Mg
2+Ion concentration has been avoided the pipe fitting explosion that causes because of lack of water and because of the Ca that repeatedly circulates
2+, Mg
2+Ion concentration uprises safety problems such as producing the incrustation scale blocking pipeline.High temperature pipe closer valve employing one is equipped with the mode of a usefulness, has improved the reliability of equipment.Residual heat using device can be utilized smelting the heat energy that is produced again, and reaches the effect of saving the energy.
Compared with the prior art, the utility model has saved the major cycle water pump; The heat energy of water and water deadweight produce circulation power, have saved a large amount of electric energy, have significant technological progress; In addition, the internal diameter that has designed the back-steam water pipe is greater than the technical characterictic of the internal diameter of feed pipe, has overcome the technology prejudice that conventional conventional techniques adopts isometrical pipe to carry in water passage circulation system, and therefore, the utility model has possessed creativeness.
