When threshold value, auto-controlling valve for water level 240 is closed, and water flow is stopped to enter tank.The present invention has no specifically the water level of tank
It limits, according to practical condition, so that the water in tank is mixed by the cold air of the water mist spraying head water mist formed and entrance
After conjunction, enough air mist mixtures can be formed and enter sinter cooler.
Because easily there is air quantity leakage problem in the upper and lower part of sinter in sinter cooler, it is preferable that sintering
Mine residual neat recovering system further includes sensor, is in sinter cooler import and/or sinter cooler outlet for sensing
It is no to there is leakage, when sensor senses leakage, increase the air inflow for entering inlet duct 100, is mixed with increasing from water mist
The air mist mixture amount that device 200 exports, thus the air mist mixture total amount for keeping sinter cooler 300 to export
It is constant, so that air mist mixture adequately cools down the sinter bed of material in sinter cooler 300.
Preferably, sinter cooler 300 includes multiple sintering according to sinter temperature to the sequence from high temperature to low temperature

It attaches together and sets outlet and connect with the import of II area's sinter, the outlet of I area's sinter and the outlet of II area's sinter are and waste heat
Connected using the import of device 400, the outlet of circulating fan 500 respectively with the import of I area's sinter and II area's sinter into
Mouth connection, wherein residual heat using device 400 can be waste heat boiler.
Air mist mixture enters sinter cooler from the import of II area's sinter, in sinter cooler 300
The cooling sinter bed of material, absorbs heat, the air mist mixture to heat up after heat exchange the outlet from I area's sinter and IIth area respectively
The outlet of sinter enters waste heat boiler 400 through the import of waste heat boiler 400, after waste heat boiler recycles heat, into following
In ring blower 500, the air mist mixture transported through circulating fan 500 import from I area's sinter and the sintering of IIth area respectively
The import of mine enters the cooling mineral aggregate layer of sinter cooler 300.
Since each section sinter of sinter cooler has air quantity leakage problem, and leakage rate can be negative with sintering
The variation of lotus and change, it is preferable that be equipped in connecting pipe of the outlet with the import of II area's sinter of circulating fan 500
Regulating valve 600, the air mist mixture that circulating fan 500 exports enter sinter cooler 300 by regulating valve 600, lead to
The valve opening control for overregulating regulating valve 600 exports from circulating fan 500 respectively and exports entrance from water mist mixing arrangement 200
The ratio of the air mist mixture of sinter cooler 300 guarantees the air water of the outlet of I area's sinter and II area's sinter
Mist amount of the mixture is constant.
When the inleakage of sinter cooler 300 increases, the valve opening of regulating valve 600 is adjusted, so that from circulated air
The air mist mixture that 500 import of machine enters II area's sinter is reduced, hence into the air mist mixture of I area's sinter
Increase, is offset with the air quantity leakage rate of I area's sinter, so that the air mist mixture total amount exported away from I area's sinter
It remains unchanged, meanwhile, the air mist mixture total amount into II area's sinter can reduce, and be blasted by increasing air blower 100
The air inflow of water mist mixing arrangement 200 makes the air water mist for entering II area's sinter from the outlet of water mist mixing arrangement 200 mixed
The total amount for closing object increases, and balances the reduction of the air mist mixture total amount of II area's sinter, so that the outlet of II area's sinter
Air mist mixture total amount remains unchanged.
When the inleakage of sinter cooler 300 is reduced, the valve opening of regulating valve 600 is adjusted, so that from circulated air
The air mist mixture that 500 import of machine enters II area's sinter increases, hence into the air mist mixture of I area's sinter
It reduces, so that the air mist mixture total amount exported away from I area's sinter remains unchanged, meanwhile, into II area's sinter
Air mist mixture total amount will increase, by reduce air blower 100 air inflow make from water mist mixing arrangement 200 export
Air mist mixture total amount into II area's sinter is reduced, so that the air mist mixture of II area's sinter outlet
Total amount remains unchanged.
As shown in Figure 1, the preferred embodiment of the present invention can illustrate from two parts process.
Exhaust gas process: air blower 100 enters in water mist mixing arrangement 200 from sucking air in atmosphere, in spraying device
Enter II area's sinter of sinter cooler Zhong after the water mist mixing of ejection, by II area's sinter of sinter cooler
After the heat exchange of the sinter bed of material, into waste heat boiler 400；It exchanges heat in I area's sinter of sinter cooler by the sinter bed of material
High-temp waste gas afterwards enters in waste heat boiler 400；Two sections of exhaust gas is after the heat exchange of waste heat boiler 400, into circulating fan 500
In, by circulating fan 500 pressurization after, all the way enter I area's sinter of sinter cooler in, all the way by regulating valve 600 into
Enter in the cooling II area's sinter of sinter；It leaks out since sinter cooler 300 exists in the upper and lower part of sinter, thus it is whole
The air supplement that the air quantity that a scheme for exhaust gas circulation system is missed is blasted by air blower 100；Since inleakage can be with sintering load
Variation and change, when sinter cooler inleakage increase when, by adjust regulating valve 600 so that into I area's sinter
Air circulation increases, and overcomes the I increased factor of area's sinter inleakage, guarantees that the air quantity of I area's sinter outlet remains unchanged, this
When into II area's sinter air circulation reduce, in order to guarantee II area's sinter outlet air quantity it is constant, increase air blower 100
Power output；When sinter cooler inleakage is reduced, by adjusting regulating valve 600, so that into the circulated air of I area's sinter
Amount reduces, the factor for overcoming I area's sinter inleakage to reduce, and guarantees that the air quantity of I area's sinter outlet remains unchanged, at this moment enters
The air circulation of II area's sinter increases, and the air quantity in order to guarantee the outlet of II area's sinter is constant, reduces going out for air blower 100
Power.
Recirculated water process: the water in water mist mixing arrangement 200 in tank 210 is extracted out by water pump 230, is squeezed into and is arranged in water
It in spraying device in mist mixing arrangement 200, is sprayed by multiple water mist spraying heads of spraying device, is come in the drum of air blower 100
Air mixing, the water mist for not entering sinter cooler 300 partially condenses into water droplet, into the tank of water mist mixing arrangement
In 210.It is supplemented by the water that air is brought into sinter machine by external complement water flow, a water level is set on makeup water stream pipeline certainly
Dynamic control valve 240, auto-controlling valve for water level 240 can automatically control the water level in tank 210, when the water level mistake of tank 210
When low, auto-controlling valve for water level 240 is automatically opened, when the water level of tank 210 is excessively high, water level autocontrol valve is automatically closed
240。
