Technical problem to be solved in the utility model is, overcomes the deficiency of above-mentioned background technology, it is provided that a kind of cement kiln
Head waste heat First air device, can significantly improve the efficiency of combustion of rotary kiln, can effectively utilize kiln hood waste gas residual heat, it is achieved low
Grade heat recovery, reaches energy cascade utilization.
This utility model solves its technical problem and employed technical scheme comprise that, a kind of cement kiln head waste heat First air dress
Put, including aerator, heat exchanger, the first electric butterfly valve, the second electric butterfly valve, first manual butterfly valve, the second Hand-operated butterfly valve, the 4th
Hand-operated butterfly valve；Described first electric butterfly valve is connected with aerator, the outlet of described aerator and the air side air inlet of heat exchanger
Being connected, the air side gas outlet of described heat exchanger is connected with the second Hand-operated butterfly valve；The exhaust gas side air inlet of described heat exchanger and
Two Hand-operated butterfly valves are connected, and the exhaust gas side gas outlet of described heat exchanger is connected with first manual butterfly valve；Described second electric butterfly valve
Inlet ductwork communicates with air, and the export pipeline of described second electric butterfly valve and the export pipeline of the second Hand-operated butterfly valve are connected.
Further, between import and the outlet of first manual butterfly valve of described second Hand-operated butterfly valve and be connected to the 3rd hand adjustment
Valve.
Further, the air side gas outlet of described heat exchanger is provided with temperature sensor.
Compared with prior art, advantage of the present utility model is as follows: First air inlet temperature is improved about 40 DEG C, can be notable
Improve the efficiency of combustion of rotary kiln, can effectively utilize kiln hood waste gas residual heat, it is achieved tow taste heat reclaims, reach energy step profit
With.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in further detail by specific embodiment.
With reference to Fig. 1, the present embodiment includes aerator 2, heat exchanger the 3, first electric butterfly valve the 1, second electric butterfly valve 8, first
Hand-operated butterfly valve the 4, second Hand-operated butterfly valve 5 and the 4th Hand-operated butterfly valve 7；First electric butterfly valve 1 is connected with aerator 2, going out of aerator 2
Mouth is connected with the air side air inlet of heat exchanger 3, and the air side gas outlet of heat exchanger 3 is connected with the second Hand-operated butterfly valve 7；Heat exchanger
Exhaust gas side air inlet and second Hand-operated butterfly valve 5 of 3 are connected, and the exhaust gas side gas outlet of heat exchanger 3 is connected with first manual butterfly valve 4；
The inlet ductwork of the second electric butterfly valve 8 directly communicates with air, the export pipeline of the second electric butterfly valve 8 and the second Hand-operated butterfly valve 7
Export pipeline be connected, between import and the outlet of first manual butterfly valve 4 of the second Hand-operated butterfly valve 5 and be connected to the 3rd Hand-operated butterfly valve
6.The air side gas outlet of heat exchanger 3 is provided with temperature sensor.
This utility model device and rotary cement kiln system with the use of, during use, the second Hand-operated butterfly valve 7 is returned with cement
The roots blower entrance of rotary kiln system is connected；The import of the second Hand-operated butterfly valve 5 is connected with the dust-precipitator of rotary cement kiln system,
The outlet of first manual butterfly valve 4 is connected with the exhaust blower of rotary cement kiln system；During work, open the first electric butterfly valve 1, drum
Blower fan 2, first manual butterfly valve 4 and the second Hand-operated butterfly valve 5, the natural wind brought by aerator 2 is given up with kiln hood in heat exchanger 3
Gas heat exchange, kiln hood waste gas is discharged through exhaust blower；Natural wind after heating delivers to roots blower porch, is sent by roots blower
Enter a rotary kiln combustion air as rotary kiln.After the temperature of heat exchanger 3 air side gas outlet is more than 60 DEG C, the second electronic butterfly
Valve 8 is opened, and is controlled the aperture of the second electric butterfly valve 8 by the temperature of heat exchanger 3 air side gas outlet, thus determines the ginseng of cold wind
Enter amount.When heat exchanger 3 fault or maintenance, close the first electric butterfly valve 1, aerator 2, first manual butterfly valve 4, second-hand
Dynamic butterfly valve 5, the 4th Hand-operated butterfly valve 7, open the 3rd Hand-operated butterfly valve 6, the second electric butterfly valve 8 standard-sized sheet, system recovery is not for add this reality
By the rotary cement kiln system pattern of new device.
By this utility model device, First air inlet temperature can be improved about 40 DEG C, the combustion of rotary kiln can be significantly improved
Burn efficiency, can effectively utilize kiln hood waste gas residual heat, it is achieved tow taste heat reclaims, and reaches energy cascade utilization.
