The purpose of this utility model is to provide a kind of simple structure, can avoid steam contamination plant area, recycling water
The electric arc furnaces environmental protection air cooling mechanism of resource.
For achieving the above object, air-cooled water-cooled electric arc furnaces environmental protection cooling body of the present utility model include electric arc furnaces,
Heat exchanger and tank, electric arc furnaces are provided with for cooling down the water leg of electric arc furnaces；
Heat exchanger includes that the length direction in heat exchange box, heat exchange box along heat exchange box is provided with inner tube, between inner tube outer surface is uniform
Every being provided with some heat exchange discs；The water inlet end of inner tube is connected with the first pipeline, the top of the water leg of the first pipeline connection electric arc furnaces
Portion；The water side of inner tube is connected with the second pipeline, and the second pipeline is passed through a side bottom of tank；Heat exchange box is in inner tube water inlet end
Place is connected with the 3rd pipeline, the 3rd pipeline is upwardly extended and its distal opening is above the ground level more than 10 meters,
Heat exchange box is connected with the 4th pipeline at inner tube water side, and the 4th pipeline is provided with for air is sent into heat exchange box
Blower fan；
Tank bottom is connected with the 5th pipeline in the opposite side of the second pipeline, and the 5th pipeline connects the water leg of electric arc furnaces
Bottom；5th pipeline be provided with for by tank water send into electric arc furnaces water leg in first circulation pump.
Multiple heat exchanging holes are evenly distributed with the heat exchange disc.
Using the utility model, steam in production process can be avoided completely from permeating into the situation of on-site, be comprehensively utilized
Water-cooled and air-cooled two kinds of means, cool down electric arc furnaces using the mode of water-cooled, using air-cooled mode cooling circulating water, structure letter
Single, heat exchange efficiency is higher, can recycle water resource, effectively cools down electric arc furnaces, with good production application value and ring
Support value value.
The setting of heat exchanging holes, both reduces heat exchange resistance, the flowing that be conducive to water heat exchange box in of the disc to water, adds again
Fast heat transfer rate between water and heat exchange disc.
If the second pipeline is not passed through the bottom of tank, but opening is in tank ullage, then from second
Pipeline still can flow out a small amount of steam, cause a small amount of steam contamination to environment；Second pipeline is not passed through the bottom of tank, then
Steam can be avoided completely to permeate into the phenomenon in air.
3rd pipeline is upwardly extended and its distal opening is above the ground level more than 10 meters, be prevented from the 3rd pipeline opening too low
And raise surface air temperature, deteriorate plant area's working environment.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A direction views of Fig. 1.
Specific embodiment
In Fig. 1, direction shown in arrow is the flow direction of the fluid at this.
As depicted in figs. 1 and 2, air-cooled water-cooled electric arc furnaces environmental protection cooling body of the present utility model include electric arc furnaces 1,
Heat exchanger and tank 2, electric arc furnaces 1 are provided with for cooling down the water leg of electric arc furnaces 1；Electric arc furnaces 1 and its water leg are this
Field routine techniques, not shown water leg.
Heat exchanger includes that heat exchange box 3, the length direction in heat exchange box 3 along heat exchange box 3 are provided with inner tube 4, and 4 outer surface of inner tube is equal
Even be interval with some heat exchange discs 5；The water inlet end of inner tube 4 is connected with the first pipeline 6, and the first pipeline 6 connects the water of electric arc furnaces 1
The top of chuck；The water side of inner tube 4 is connected with the second pipeline 7, and the second pipeline 7 is passed through a side bottom of tank 2；Heat exchange box
3 are connected with the 3rd pipeline 8 at 4 water inlet end of inner tube, the 3rd pipeline 8 is upwardly extended and its distal opening is above the ground level 10 meters with
On, it is prevented from the 3rd pipeline 8 and is open too low and raises surface air temperature, deteriorates plant area's working environment.
Heat exchange box 3 is connected with the 4th pipeline 9 at 4 water side of inner tube, and the 4th pipeline 9 is provided with and changes for sending into air
The blower fan 10 of hot tank 3；
2 bottom of tank is connected with the 5th pipeline 11 in the opposite side of the second pipeline 7, and the 5th pipeline 11 connects electric arc furnaces 1
Water leg bottom；5th pipeline 11 be provided with for by tank 2 water send into electric arc furnaces 1 water leg in first
Circulating pump.
Multiple heat exchanging holes 12 are evenly distributed with the heat exchange disc 5.The setting of heat exchanging holes 12, had both reduced heat exchange disc
The resistance of 5 pairs of water, be conducive to flowing of the water in heat exchange box 3, accelerate the heat transfer rate between water and heat exchange disc 5 again.
During work, start blower fan 10 and first circulation pump 19, the water in tank 2 is sent into electric arc furnaces by first circulation pump 19
In 1 water leg, so as to cool down electric arc furnaces 1；The coolant-temperature gage flowed out from water leg is higher, such as directly discharge will produce substantial amounts of
Steam, pollutes working environment, plant area's wall is damaged because long-term moist.In the utility model, the water of outflow from water leg
Heat exchange box 3 is sent into, during by the inner tube 4 of heat exchange box 3, heat exchange occurs with the cold wind outside pipe.The setting of heat exchange disc 5 can be big
Width improves heat exchange efficiency, and does not excessively affect the flowing of air because of the presence of heat exchanging holes 12.
After heat exchange, the temperature of the water flowed out from 1 water leg of electric arc furnaces is greatly reduced, finally by 7 note of the second pipeline
Enter the bottom of tank 2.If the second pipeline 7 is not passed through the bottom of tank 2, but opening is in 2 ullage of tank,
So a small amount of steam still can be flowed out from the second pipeline 7, cause a small amount of steam contamination to environment；Second pipeline 7 is not passed through storage
The bottom in pond 2, then can avoid steam to permeate into the phenomenon in air completely.First circulation pump 19 makes this part water in electric arc
Circulate between the water leg of stove 1, heat exchange box 3 and tank 2, constantly cool down electric arc furnaces 1.
Air is sent into heat exchange box 3 by blower fan 10, the flow direction of flow direction of the air-flow in heat exchange box 3 and water in inner tube 4 just phase
