Description

A kind of compensation process and device for active carbon in flue gas purification device

Technical field

The present invention relates to sintering gas purifying technical fields more particularly to a kind of for active carbon in flue gas purification device Compensation process and device.

Background technique

Currently, sintering flue gas accounts for enterprise in the enterprise (such as iron and steel enterprise) that adjoint sintering flue gas generates in most productions The overwhelming majority of industry disposal of pollutants total amount discharges caused atmosphere pollution by sintering flue gas to mitigate, it is net to generally use flue gas Makeup is set, and activated carbon adsorption sintering flue gas is held in the adsorption tower of flue gas purification device, to realize the desulfurization to sintering flue gas With the purified treatments such as denitration.

With reference to Fig. 1, shown in fig. 1 is a kind of structural schematic diagram of flue gas purification device in the prior art.It can in conjunction with Fig. 1 Know, which includes: Analytic Tower 1, adsorption tower 2, the first conveyer 3, second conveyor 4, weighing belt 5 and live Property charcoal storehouse 6, the first conveyer 3 and second conveyor 4 are bucket conveyor, and the quantity of adsorption tower 2 can be one, can also Think multiple.Wherein, active carbon can be held in each adsorption tower 2, includes for absorbing into sintering flue gas therein Pollutant including oxysulfide, nitrogen oxides and dioxin.Analytic Tower 1 is used for the hot recycling of active carbon.Active carbon storehouse 6 is used for The active carbon being lost in initial active carbon and gas cleaning treatment process is provided for each adsorption tower 2.First conveyer 3 and Two conveyers 4 are used to the transport of active carbon.

In Fig. 1, after the initialization of flue gas purification device starts, active carbon is discharged from active carbon storehouse 6, passes through weighing belt 5 and second conveyor 4 be transported in Analytic Tower 1, in Analytic Tower 1 be resolved after, be analytically discharged in tower 1, pass through first Conveyer 3 is transported in each adsorption tower 2, carries out purified treatment to the sintering flue gas for entering adsorption tower 2 in adsorption tower 2, Later, the active carbon for being adsorbed with sintering flue gas is discharged from adsorption tower 2, is transported to Analytic Tower 1 again by second conveyor 4 In parsed, for the subsequent decontamination process to sintering flue gas, so by active carbon in Analytic Tower 1 and adsorption tower 2 In move in circles, purified treatment persistently is carried out to sintering flue gas, in the process, according to the loss situation of active carbon in system, Active carbon storehouse 6 can be used, active carbon is supplemented in due course for system by weighing belt 5.

During using active carbon storehouse 6 to supplement active carbon for system, need to accurately control the lower stream of weighing belt 5 Amount, if the blanking flow of weighing belt 5 is too big, the discharge flow of the blanking flow of weighing belt 5 and all adsorption towers 2 and will More than the maximum transport capacity of second conveyor 4, big carbon content active will be overflowed from second conveyor 4, cause active carbon Waste.If the blanking flow of weighing belt 5 is too small, it will cause active carbon supplement deficiency in system, reduce system to sintering flue gas Detergent power.Therefore, when using active carbon storehouse 6 to supplement active carbon for system, need to accurately control weighing belt 5 can permit Perhaps maximum blanking flow operation, so that the blanking flow of weighing belt 5 and the sum of the discharge flow of all adsorption towers 2 and second are defeated The maximum transport capacity of machine 4 is sent to reach balance, to avoid that active carbon waste occurs and reduce purification of the system to sintering flue gas The problem of ability.

In the prior art, it will usually burying scraper be set in the lower section of second conveyor 4, then pass through detection burying scraper Exit whether have the active carbon without using, to control the blanking flow of weighing belt.If detecting burying scraper There is the active carbon without using in exit, and illustrates have the active carbon without using to overflow from second conveyor 4, weighing belt 5 The sum of the discharge flow of blanking flow and all adsorption towers 2 greater than second conveyor 4 maximum transport capacity, then, under The spilling of the blanking flow elimination activity charcoal of naughty belt scale 5.If detecting the exit of burying scraper not without using Active carbon, then it is assumed that the active carbon without using is not overflowed from second conveyor 4, would not be to the lower stream of weighing belt 5 Amount is adjusted.Thus it is possible, on the one hand, the active carbon without using can not be avoided to overflow in time, however it remains active carbon waste Situation；On the other hand, it for the lesser situation of blanking flow of weighing belt 5, can not make adjustment in time, to not can avoid hair The problem of giving birth to detergent power of the reduction system to sintering flue gas.

Therefore, in the existing compensation process for active carbon in flue gas purification device, due to being unable to accurately control belt The blanking flow of scale still can waste and reduce detergent power of the system to sintering flue gas, applicability there is a situation where active carbon It is poor.
