Active carbon through regenerating in regenerator, its most pollution sources have been resolved and have decomposed, conventionally make to remain in wherein less than the micropollution source of 1wt%, discharging opening place at regenerator arranges sieve, thereby the active carbon size after assurance regeneration is just transported in adsorption tower 4 and re-uses more than maintaining 2.8mm.The dust arrester that the active carbon of regeneration and new active carbon together arrange by adsorption tower top is housed in the storage tank 4s of top after removing fine dust.The pipeline that active carbon is connected along top storage bin 4c against gravity from top storage tank moves down, action by switch baffle plate on pipeline and pipeline remains airtight successively, and then the second top fed pipe 4m via module top enters in the storage bin 4c of top.Be contained in after the active carbon material feeding in the storage bin of top, at denitration chamber 4b, by catalysis, carry out denitration (denitrogenation), at desulfurization chamber 4a, by adsorption function, carry out desulfurization, in these denitrations and sweetening process, active carbon suitably stays for some time, and then in order to regenerate, from the desulfurization chamber 4a of module, discharges.Active carbon temporarily leaves in bottom storage bin 4l and bottom discharge tank 4k after discharging from desulfurization chamber 4a according to the time of programming on time, then with carrying equipment, discharges.
Active carbon after active device spray and be together delivered to regenerator from the fresh active carbon of fresh active carbon storage bin supply, raises from top through heating zone temperature in order to regenerate, and starts to resolve when temperature surpasses 300 ° of C.The concentrated sulfur dioxide forming heating zone temperature is raised to 400-450 ° of C and resolves, decomposes from active carbon, together through degas zone, is delivered to sulfuric acid manufacturing equipment with other resolved pollution sources.Active carbon completes after parsing in degas zone, move down into bottom coohng district, the outer gas of being introduced by pressure fan carries out cooling, in addition gas is obtained thermal source and is heated up by heat exchange in the process of cooling active carbon, about 200-250 ° C, be heated to again 500-600 ° of C in heat riser after, move on to heating zone, the temperature of active carbon is raise, finally from regenerator, deliver to atmosphere.Active carbon is from regenerator is discharged, and through sifting out, the active carbon that is only greater than 2.8mm enters in adsorption tower again, the active carbon micro mist leaching or other collection of granule less than 2.8mm, re-uses from sieve.According to the amounts of activated carbon from system filtering, from fresh active carbon storage bin, supply the fresh active carbon of same amount.
Active carbon in adsorption module is as the medium of removing pollution sources in flue gas, need to form benign cycle, in other words, in adsorption tower, by round and smooth discharging and charging, the pollution sources in adsorption tower are extracted out and regenerated rapidly, then the active carbon of regeneration is fed intake again, and the active carbon of discharging in adsorption tower is when stop, for fear of phenomenons such as dewfall and corrosion, occur, the discharge rate of active carbon and internal circulating load, with iron-smelter sinter fume sulphur oxide concentration, 220ppm is as the criterion, and comparing with the active carbon total amount of whole module should be within the scope of 0.15-0.2wt%; Active carbon is carried the maximum machine ability of equipment, and comparing with active carbon total amount should be within the scope of 0.3 – 0.4wt%; Sulfoxide concentration is higher, and the machine capability of internal circulating load and conveying equipment should be improved accordingly.Active carbon is under the state of the pollution sources such as absorption oxysulfide, when stopping for a long time in adsorption tower 4, regenerator and other storage tanks, for fear of occurring in phenomenons such as the following dewfall/corrosion of acid dew point, heater, insulation are taked to and/or with measures such as nitrogen fillings in the outside of container, reduce and the contacting of oxygen.Active carbon has high abrasiveness, for fear of the mechanical wear generation of carrying equipment activated carbon granule to be pulverized completely or weakened, should select friction can be dropped to minimum equipment.Conventionally to use the low abrasiveness such as bucket conveyor, flexible rubber conveyer belt to carry equipment.When carrying active carbon, likely there is hidden danger in forward and backward technique, therefore the surge tank of suitable capacity need to be installed to pooling feature can be provided; Active carbon and be attracted to pollution sources wherein in adsorption tower 4, regenerator and other storage tanks during long-term stop, takes heater, insulation and/or with measures such as nitrogen fillings, in order to avoid in phenomenon generations such as the following dewfall/corrosion of acid dew point to container.
The active carbon that the utility model is used is to be, after brown coal 80% and bituminous coal 20% coordinate with tar (pitch), through charing, to process by percentage by weight, finally through activation processing, makes.Certainly, the utility model also can be used other active carbons or activated coke.
Existing active carbon, active carbon of the present utility model and the active carbon of the present utility model after chemokinesis have been carried out to the test to oxysulfide adsorption capacity, and measured the oxysulfide being adsorbed in active carbon.Result of the test is presented in accompanying drawing 4.The active carbon of the present utility model activating after chemical addition agent sprays is stronger than other two kinds of active carbons to the adsorption capacity of oxysulfide.After it should be noted that active carbon of the present utility model activates, in absorption and parsing circulation repeatedly, its oxysulfide adsorption capacity remains well, never goes down.This result of the test shows, the active carbon using in flue gas purification system its machinery and chemical characteristic in circulation technology are repeatedly faded.Active carbon of the present utility model after chemokinesis will improve following functions: improve SWC(desulfurization load factor); By keeping chemical group, reduce active carbon wearing and tearing; Avoid the inner clogging of adsorption tower to occur; In the denitrification process of adsorption tower, reduce ammonia consumption.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
