Adopt traditional sintering process and exhausting system, its discharge amount of exhaust gas~2500nm 3T -1Burn solid fuel consumption 55kgt -1Burn productivity of sintering machine 1.4tm -2H -1, power consumption~45kWht -1Burn discharge capacity~660gt -1Burn waste gas SO xConcentration of emission~90ppm.For more and more severe control target, adopt the desulphurization system of this sintering process and exhausting system, construction investment is big, and this is that concentration is rare because discharge amount of exhaust gas is big, and the desulfurization difficulty is big, makes the desulphurization system investment increase.
The utility model content
In order to overcome the above-mentioned traditional sintering process and the defective of exhausting system, task of the present utility model provides a kind of improved sintering machine circulation sintering exhausting system configuration, and it has solved, and existing desulphurization system is big because of discharge amount of exhaust gas, concentration is rare, the desulfurization difficulty makes the problem that construction investment increases greatly.
Technical solution of the present utility model is as follows:
A kind of sintering machine circulation sintering exhausting system configuration, it comprises exhausting system, sintering machine, ignition furnace, sintering large flue, and the bellows of arranging in order, it also comprises circulation sintering fan housing, blower fan, deduster, and waste gas spacer assembly;
Described circulation sintering fan housing is configured in and is positioned at other sintering machine charge level top, igniting furnace side;
The afterbody of described sintering large flue is connected with the pipeline of UNICOM to the sintering fan housing that circulates;
Described blower fan is installed on the pipeline that leads to circulation sintering fan housing;
Described deduster is installed on the pipeline that leads to blower fan and circulation sintering fan housing;
Described waste gas spacer assembly comprises the first waste gas spacer assembly and the second waste gas spacer assembly that is used for the distribution of gas amount, the first waste gas spacer assembly is installed in the pipeline that disposes between sintering large flue afterbody and the deduster, and the second waste gas spacer assembly is installed in the sintering large flue that is positioned at sintering machine afterbody bellows.
Adopt sintering machine circulation sintering exhausting system configuration of the present utility model, energy effective ground energy-saving and emission-reduction, make the sinter fume discharge capacity reduce to 70% of normal sintering technology, do not reduce simultaneously the SINTERING PRODUCTION ability, construction investment also approaches normal sintering technology, thereby satisfied the environmental requirement of increasingly stringent in the world, satisfied the needs that the investor reduces investment simultaneously.
Adopt circulation sintering configuration of the present utility model, extraction sintering machine tail oxygen content height, the portion gas that temperature is high reclaim the sintering again that is used for sintering machine, make full use of waste gas residual heat, reduce the outer discharge capacity of waste gas, help energy-conservation and environmental protection.
Description of drawings
Fig. 1 is the schematic diagram of sintering machine normal sintering exhausting system configuration.
Fig. 2 is the schematic diagram of a kind of sintering machine circulation sintering exhausting system configuration of the present utility model.
The specific embodiment
Referring to Fig. 2, the utility model is a kind of sintering machine circulation sintering exhausting system configuration, it comprises exhausting system 11, sintering machine 13, ignition furnace 14, circulation sintering fan housing 15, blower fan 16, sintering large flue 17, deduster 18, waste gas spacer assembly, and several bellows 21 of arranging in order, bellows 21 indicate the bellows numbering.Number in the figure 12 is gas flows.
At the other circulation sintering fan housing 15 that disposes of the side of ignition furnace 14, circulation sintering fan housing 15 is installed in sintering machine 13 charge levels top.
As shown in Figure 2, the afterbody of sintering large flue 17 is connected with the pipeline 22 of UNICOM to the sintering fan housing 15 that circulates, and blower fan 16 and deduster 18 are installed on pipeline 22, and blower fan 16 is installed in the back of deduster 18.
The waste gas spacer assembly comprises that the first waste gas spacer assembly 20 and 19, two waste gas spacer assemblys of the second waste gas spacer assembly all are used for the distribution of gas amount.The first waste gas spacer assembly 20 is installed in the pipeline 22 of configuration between sintering large flue 17 afterbodys and the deduster 18, and the second waste gas spacer assembly 19 is installed in the sintering large flue 17 that is positioned at sintering machine 13 afterbody bellows 21 (end numbering).Installing waste gas spacer assembly is in order to choose cycling hot waste gas, the first waste gas spacer assembly 20 plays the effect that sintering machine afterbody bellows waste gas is connected to the circulation sintering system, and the second waste gas spacer assembly 19 plays the effect that the bellows waste gas of sintering machine afterbody bellows waste gas and front is kept apart.
For the waste gas spacer assembly, can be according to the concrete condition of sintering machine flue and the different demands of production firm, the position of designing different waste gas spacer assemblys and the waste gas spacer assembly being installed.
