The air mist mixture that the import of machine 500 enters II area's sintering deposit is reduced, hence into the air mist mixture of I area's sintering deposit
Increase, offset with the air quantity leakage rate of I area's sintering deposit so that the air mist mixture total amount exported away from I area's sintering deposit
Keep constant, meanwhile, the air mist mixture total amount into II area's sintering deposit can reduce, and be blasted by increasing air blower 100
The air inflow of water smoke mixing arrangement 200 to mix into the air water smoke of II area's sintering deposit from the outlet of water smoke mixing arrangement 200
The total amount increase of compound, balances the reduction of the air mist mixture total amount of II area's sintering deposit so that the sintering deposit outlet of IIth area
Air mist mixture total amount keeps constant.
When the inleakage of sinter cooler 300 is reduced, the valve opening of regulating valve 600 is adjusted so that from circulated air
The import of machine 500 enters the air mist mixture increase of II area's sintering deposit, hence into the air mist mixture of I area's sintering deposit
Reducing so that the air mist mixture total amount exported away from I area's sintering deposit keeps constant, meanwhile, into II area's sintering deposit
Air mist mixture total amount can increase, exported by the air inflow for reducing air blower 100 from water smoke mixing arrangement 200
Air mist mixture total amount into II area's sintering deposit is reduced, and then causes the air mist mixture of IIth area sintering deposit outlet
Total amount keeps constant.
As shown in figure 1, the preferred embodiment of the present invention can illustrate from two parts flow.
Waste gas flow：Air blower 100 sucks air into water smoke mixing arrangement 200 from air, and in sprayer unit
Enter the area's sintering deposits of sinter cooler Zhong II after the water smoke mixing of ejection, by the area's sintering deposit of sinter cooler II
After the heat exchange of the sintering deposit bed of material, into waste heat boiler 400；Exchanged heat in the area's sintering deposit of sinter cooler I by the sintering deposit bed of material
High-temp waste gas afterwards enters in waste heat boiler 400；Two sections of waste gas is after the heat exchange of waste heat boiler 400, into circulating fan 500
In, after the pressurization of circulating fan 500, all the way into the area's sintering deposit of sinter cooler I, enter all the way by regulating valve 600
Enter sintering deposit to cool down in II area's sintering deposit；Leaked out because sinter cooler 300 exists in the upper and lower part of sintering deposit, thus it is whole
The air supplement that the air quantity that individual scheme for exhaust gas circulation system is missed blasts by air blower 100；Because inleakage can be with sintering load
Change and change, when sinter cooler inleakage increases, by adjusting regulating valve 600 so that into I area's sintering deposit
Air circulation increase, overcomes the I increased factor of area's sintering deposit inleakage, ensures that the air quantity of Ith area sintering deposit outlet remains unchanged, this
When reduced into the air circulation of II area's sintering deposit, in order to ensure that the air quantity of II area sintering deposit outlet is constant, increase air blower 100
Output；When sinter cooler inleakage is reduced, by adjusting regulating valve 600 so that into the circulated air of I area's sintering deposit
Amount reduces, the factor for overcoming I area's sintering deposit inleakage to reduce, and ensures that the air quantity of Ith area sintering deposit outlet remains unchanged, at this moment enters
The air circulation increase of II area's sintering deposit, in order to ensure that the air quantity of IIth area sintering deposit outlet is constant, reduce going out for air blower 100
Power.
Recirculated water flow：Water in water smoke mixing arrangement 200 in tank 210 is extracted out by water pump 230, is squeezed into and is arranged in water
In sprayer unit in mist mixing arrangement 200, sprayed by multiple waterfog heads of sprayer unit, come in the drum of air blower 100
Air mixes, and the water smoke for being partly introduced into sinter cooler 300 condenses into water droplet, into the tank of water smoke mixing arrangement
In 210.Supplemented by the water that air is brought into sintering deposit machine by external complement current, 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 up, when the water level of tank 210 is too high, automatic closing water position autocontrol valve
240。
