It establishes.Attached drawing is different, then corresponding position relationship is also possible to change therewith, therefore cannot be interpreted as with this to protecting model
The restriction enclosed.
As shown in Figure 1, a kind of slag granulating takes hot systems, including can be used in slag stream being transported to from slag mouth 1 molten
Slag particle takes slag stream conveying device, granulating device 11, heat-exchanger rig 6 and the regulation device of thermal.Heat-exchanger rig 6 can be selected
Boiler or other heat exchangers.
Slag stream conveying device includes that slag goes out circulation road 2, slag chute 3 and overflow plate 5 and for adjusting the overflow plate
The overflow plate control device at angle of inclination.Slag goes out circulation road 2 and is arranged below the slag mouth 1 of slag device such as blast furnace, tilts
Setting.The setting of slag chute 3 goes out in slag below 2 end of circulation road, is connected to granulating device 11 and heat-exchanger rig 6.The outlet of slag chute 3 is set
It sets in 6 front end of heat-exchanger rig；Overflow plate 5 is arranged in 3 outlet end of slag chute, between slag chute 3 and heat-exchanger rig 6.Overflow plate 5 is
Mobile overflow plate can move up and down in 3 outlet end of slag chute or adjust angle by rotation, molten in slag chute 3 to regulate and control
Slag depth and slag overflow height.5 top of overflow plate is in tilted layout towards 6 direction of heat-exchanger rig.
Overflow plate control device can also be used to adjust the upper and lower position of the overflow plate 5.Excess flow control includes overflowing
Flowing plate regulates and controls motor 17 and connects the overflow regulation and control transmission shaft 18 of overflow plate 5.
Granulating device 11 is arranged in the front end of heat-exchanger rig 6, and positioned at the outlet of slag chute 3 lower section；The injection of granulating device 11
Mouthful towards heat-exchanger rig 6 be arranged, and granulating device 11 jet port alignment from 3 outlet overflows of slag chute and under high-temperature slag stream,
It is injected with the cooling medium of pressure to slag stream.
Regulation device includes the temperature measuring equipment 7 being arranged on heat-exchanger rig 6, takes thermal control to fill with what temperature measuring equipment 7 was connect
Set 8 and granulation regulation and control motor 9.Temperature measuring equipment 7 is arranged on the side wall surface opposite with granulating device 11 of heat-exchanger rig 6.Thermometric
Device 7 is used to measure the temperature of heat-exchanger rig 6, and the temperature signal of heat-exchanger rig 6 is transferred to and takes heat control device 8.Take heat
Control device 8 can adjust the rotation of granulation regulation and control motor 9 according to temperature signal.Granulation regulation and control motor 9 is passed by being granulated motor
Moving axis 10 is connected with granulating device 11, can adjust granulating device 11 at a distance from heat-exchanger rig 6.Heat control device 8 is taken to select
PLC control unit.PLC is programmable logic controller (PLC)（Programmable Logic Controller）Abbreviation, it is relatively simple
It is single controllable.
High-temperature slag is flowed out from slag mouth 1, and going out circulation road 2 along slag enters slag chute 3.Slag, which goes out circulation road 2, usually to be compared
Slag chute 3 is precipitous, and quickly being flowed convenient for slag prevents from condensing.3 bottom of slag chute is tilted towards heat-exchanger rig 6,3 bottom of slag chute and level
The angle α in direction is 0 ~ 20 °, and slag stream smoothness can be made to be condensed without being detained.
Slag flows out slag chute 3 under the regulation and control of overflow plate 5 and enters 6 top of heat-exchanger rig in an overflow manner, and overflow plate 5 tilts
Arrangement is to prevent slag drip in 5 outside plate face of overflow plate.The slag that overflow goes out is sprayed in dropping process from granulating device 11
The granulation medium such as steam, high pressure water or high pressure Dual-Phrase Distribution of Gas olid that loophole sprays shuts off and moment solidifies and falls to heat exchange dress
It sets 6 or is splashed on the wall surface of heat-exchanger rig 6.6 wall surface of heat-exchanger rig uses water-cooling wall.Temperature measuring equipment 7 is arranged in heat-exchanger rig 6
On the interior side wall surface opposite with granulating device 11, and wall surface temperature signal is transmitted with taking heat control device 8 to be connected.Work as high temperature melting
Slag granulated particles be largely ejected into granulating device 11 to side wall surface when, temperature measuring equipment detects high temperature signal, by taking thermal control
Device 8 processed controls granulating device 11, and side is mobile backward or reduces the jet port pressure of granulating device 11, to reduce granulation dress
The jet length for setting 11 makes the slag particle after granulation fully fall in heat-exchanger rig 6.
As further improved scheme, the jet port direction of granulating device 11 can be in two side direction of vertical direction or level
Adjust rotation, optimization granulation effect.
3 middle part top of slag chute is additionally provided with slag trap 4, and slag trap 4 can be such that the kinetic energy of the high-temperature slag of big flow weakens,
Keep the slag flow distribution of spilling slag chute 3 more uniform.
One of embodiment is gear transmission mode as shown in Figure 2, and 5 both sides of overflow plate and slag chute 3 export both sides
It is provided with slideway 14, gear 12, rack 13, overflow plate regulation and control motor 17 is connected with overflow regulation and control transmission shaft 18, and overflow regulation and control pass
Moving axis 18 is fixed by bearing 15 and the support of holder 16.Overflow plate regulates and controls motor 17 and overflow regulation and control transmission shaft 18 is driven to rotate, into
And it is rotated with moving gear 12.Entire overflow plate 5 is driven to be risen or fallen in slideway 14 by the engagement of gear 12 and rack 13.
When slag flow increases, overflow plate regulates and controls motor 17 and rotates counterclockwise, and two side gears 12 are driven by axis connection
It rotates counterclockwise, the engagement of gear-tooth item drives entire overflow plate 5 to rise in slideway 14；When slag flow reduces, overflow plate
Regulation and control motor 17 rotates clockwise, and drives two side gears 12 to rotate clockwise by axis connection, and the engagement of gear-tooth item drives entire
Overflow plate 5 declines in slideway 14.After slag input, overflow plate 5 drops to lowest point, at this time 5 top of overflow plate and slag chute 3
Bottom is concordant, so that residual sprue in slag chute 3 is all emptied, prevents it from being condensed in slag chute 3 and influencing follow-up operation.
Overflow plate 5 can also regulate and control motor 17 and overflow regulation and control rotation axis by chain or other kinds of drive in overflow plate
It is moved under 18 drive.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
