Abstract
Sintering machine flue gas system is equipped with two flues, and one is the desulfurization flue, and another is non - desulfurization flue. Two bellows that are close to the sintering machine head all channel into the desulfurization flue with the tuber pipe, and two bellows that are close to the sintering machine afterbody are all with the leading -in non - desulfurization flue of tuber pipe, the bellows that begin to third from the bottom bellows of sintering machine afterbody till from a sintering machine head third bellows divide into two sets ofly from beginning to end to 1 small in quantity of bellows are organized after than to preceding group bellows, and preceding group bellows all channel into non - desulfurization flue with the tuber pipe organizes bellows after, and all channels into the desulfurization flue with the tuber pipe, strict press SO2 concentration and temperature distribution law optionally channels into desulfurization flue and non - desulfurization flue respectively with the sintering flue gas. Utility model can make the abundant enrichment of the SO2 in the sintering flue gas in desulfurization flue, makes non - desulfurization flue SO2 concentration be less than the emission limit value to can avoid carrying out full flue gas desulfurization to the sintering flue gas, and the increase desulphurization unit construction investment of avoiding being leaded to by full flue gas desulfurization and land used and desulfurization cost are doubled.
Description
Technical field
The utility model belongs to agglomerating plant, is a kind of sintering device flue gas system with sintering strong selectivity desulfurization performance.
Technical background
Current main flow sintering machine all takes selective desulfurization, is provided with two flues, and one of them is desulfurization duct, and another is non-desulfurization duct.The flue gas produced in sintering process, SO
2the part bellows that concentration is high are collected and are imported desulfurization duct, make SO
2be enriched in desulfurization duct, qualified discharge after follow-up desulfurization process, and SO
2the part bellows that concentration is low are collected the non-de-flue of importing and are directly discharged.Desulfurization duct SO
2enrichment degree depends on the SO of non-desulfurization duct on the one hand
2concentration limit, also will take into account flue gas flow, the equalized temperature of two flues on the other hand.Before 1 day January in 2015, sintering SO
2discharge standard performs " industrial furnace atmosphere pollutants emission standards " (GB9078-1996), SO
2emission limit is lower than 600mg/m
3, this emission limit is relatively looser, and the bellows combination causing the current main flow sintering machine of going into operation by this standard design to import desulfurization duct does not cover the whole high SO of sinter fume
2concentration section, and there is no fixed Combination, cause desulfurization duct SO
2enrichment degree is on the low side.But, from 1 day January in 2015, sintering SO
2discharge standard performs " steel sintering, pelletizing industrial air pollution thing discharge standard " (GB286620-2012), SO
2emission limit is lower than 200mg/m
3.Emission limit significantly reduces, and makes nearly all sintering machine of selective desulfurization of taking of going into operation by old plant design all face non-desulfurization duct SO
2discharge exceeds standard, and has to take non-desulfurization duct SO
2mitigation options, meanwhile, also causes manufacturing and designing of all new sintering machines that corresponding technology innovation must be taked to adapt to New emission standard.In current sintering industry, the known technical scheme addressed this problem takes full flue gas desulfurization, that is: add the non-desulfurization duct of old sintering machine and build desulfurizer, no longer arrange non-desulfurization duct to new sintering machine.The shortcoming of this technical scheme causes desulfurization process air quantity double, thus both increased desulfurizer construction investment and land used, also makes desulphurization cost be doubled.
Utility model content
The utility model aims to provide a kind of sintering device flue gas system, overcomes existing sintering machine selective desulfurization technology SO
2enrichment is on the low side, is not suitable with new SO
2the defect of discharge standard.
The utility model solves the technical scheme that its technical problem adopts: sintering device flue gas system, is provided with two flues, and one is desulfurization duct, and another is non-desulfurization duct.Bellows from sintering machine head the 3rd bellows to sintering machine afterbody third from the bottom bellows are divided into two groups, front and back, and front group of bellows are than few 1 of rear group of bellows quantity, front group of bellows all import non-desulfurization duct with airduct, and rear group of bellows all import desulfurization duct with airduct.
Bellows from sintering machine head the 3rd bellows to a sintering machine afterbody fourth from the last bellows are divided into two groups, front and back, and front group of bellows are than few 1 of rear group of bellows quantity, front group of bellows all import non-desulfurization duct with airduct, rear group of bellows all import desulfurization duct with airduct, sintering machine afterbody third from the bottom bellows are changeable bellows, have and bellows are imported desulfurization duct or non-desulfurization duct two valve position.
Two bellows airducts near sintering machine head import desulfurization duct, and two bellows airducts near sintering machine afterbody import non-desulfurization duct.
Sintering machine afterbody third from the bottom bellows are set to changeable bellows, are applicable to switch under sintering mixing material S content is less than 0.1% situation import non-desulfurization duct, switch to importing desulfurization duct when sintering mixing material S content more than 0.1%.
The beneficial effects of the utility model are: the bellows importing desulfurization duct cover the whole high SO2 concentration section of sinter fume, make the SO2 in sinter fume fully be enriched in desulfurization duct, make non-desulfurization duct SO2 concentration lower than emission limit.Simultaneously, the bellows quantity importing desulfurization duct and non-desulfurization duct is respectively close, the flue gas flow of sintering machine desulfuration flue and non-desulfurization duct, equalized temperature are taken into account, thus full flue gas desulfurization can be avoided, and the increase desulfurizer construction investment that caused by full flue gas desulfurization and land used and desulphurization cost is avoided to be doubled.
