A kind of desulfurating dust-removing equipment with air inlet system
Technical field
The invention belongs to desulfurization and dedusting field, a kind of desulfurating dust-removing equipment with air inlet system.
Background technology
Desulfurating dust-removing equipment often utilizes desulfurized dust collection column to carry out moisture film or water-fog type desulfurization and dedusting, adds desulfurizing agent, such as alkaline matter, thus reach the purpose of desulfurization and dedusting simultaneously in water.Alkali liquor can recycle.And alkali liquor is mingled with slag body or the precipitate departing from formation after desulfurization and dedusting, it precipitates in sediment fraction, thus separates discharge.Alkali liquor is circulated by pump after separating slag body.
The sediment of precipitation needs periodic cleaning to discharge.But, cleaning when, generally require certain time amount, now, properly functioning in order to not affect equipment, spray system normally works, this will cause a large amount of alkali liquor to flow out in a large number along with the discharge of sediment, and this discharges to sediment and makes troubles, such as, need again to be separated by big quantity of fluid;And this can cause the waste of alkali liquor and be likely to result in the potentially possible of environmental pollution.
