Description

Combined dust remover

The utility model belongs to combined dust remover.

Existing combined dust remover, easily stop up for overcoming shortcoming and the wet scrubber that the highly effective dry-type dust remover resistance greatly can not desulfurization, easy to wear, water consumption is many, the weak point that the sedimentation basin floor space is big, dry collector is combined into combined dust remover with wet scrubber, " doing the desulfurizing dust-collector that wet method combines " as application number 92242930, it is that dry collector is arranged under the wet scrubber, both are combined, though desulfuration efficiency height, the sedimentation basin area is little, flue dust is earlier through wet scrubber, wet scrubber is still easy to wear, easily stop up, structure is not compact.

The combined dust remover that the purpose of this utility model provides a compact conformation, be difficult for to stop up, efficiency of dust collection is high.

For achieving the above object, the utility model with a sub-dry collector of whirlwind and wet scrubber and together, dry collector is removed flue dust as first order deduster, wet scrubber is removed pernicious gas as second level deduster.The utility model is taked following structure, and it comprises a dry collector and a wet scrubber; Arrange in the dry collector shell whirlwind is installed, whirlwind is made of the core pipe on top and the cyclone body of bottom, and the upper end of core pipe is fixed on tilt clapboard, and the lower end of core pipe is stretched in the cyclone body, and the lower end of cyclone body is back taper and is fixed on diaphragm plate; Be back taper at the bottom of the dry collector shell, at the bottom of the back taper two plate flappers, the dry collector shell has gas approach under the tilt clapboard position, the outlet pipe of the water pump of wet scrubber puts in the wet scrubber shell, it is characterized in that: wet scrubber shell and dry collector shell are fixed as one side by side, vertical deflection plate is divided into cup and chamber, back to the wet scrubber shell inner cavity, bottom, forward and backward two Room communicates, and the top of cup has the above inner chamber of connection mouth and dry collector shell inclined clapboard to communicate; The dehydration baffle plate that back chamber distributes and tilts to install, exhanst gas outlet is on the top of chamber, back; Said pumping line is divided into some arm layerings and puts in the cup of wet scrubber shell, at the mouth of pipe of outlet pipe arm the atomizer of distribution spray orifice is installed, and divides into overflow launder at wet scrubber, and wet scrubber shell lower edge puts in overflow launder.

Above-mentioned combined dust remover, it is characterized in that: overfall is arranged at said overflow launder, the position, lower edge of overfall is higher than the wet scrubber lower edge, be lower than two sedimentation basins arranged side by side that are divided into by dividing plate in addition under the position of this overfall, the upper edge of two sedimentation basins is higher than the upper edge of dividing plate, wherein a sedimentation basin is near overfall, and the water inlet pipe of water pump puts in another sedimentation basin.

The utility model is work like this: the ash-laden gas that boiler is discharged enters low-resistance multitube dry collector through gas approach, enter the cyclone body of whirlwind from the top down, enter the core pipe then from bottom to top, because centrifugation, nearly 90% flue dust is separated in the flue gas gets off, and two plate flappers are drained through the bottom; The flue gas that contains a small amount of trickle flue dust then is downward by the cup that the connection mouth enters wet scrubber, flue gas after the spray washing of the multilayer atomizer in cup, neutralization, purification, desulfurization, the further dedusting upwards returns into the chamber, back under vertical deflection plate, this moment is because the dirt in the centrifugal force flue gas falls into the water of overflow launder, the flue gas of cleaning is upwards flowed through multilayer dewatering plate dehydration back by top exhanst gas outlet discharge deduster through the chamber, back, the efficiency of dust collection of this combined dust remover ≮ 95%, desulfuration efficiency ≮ 70%, dust remover resistance is less than 1000Pa.Water pump is constantly supplied with atomizer to water through outlet pipe and is washed for spray from sedimentation basin.

Because this combined dust remover takes said structure, not only efficiency of dust collection is higher, and compact conformation, be difficult for blocking, reliable, simple to operate; Wet scrubber is stretched in some arm layerings of outlet pipe, live lower edge purification, the desulfurization degree height of wet scrubber with the water seal of overflow launder, deposition ash amount in overflow launder of the present utility model in addition, the sedimentation basin is few, it only is about 1/5th of granite wet type deduster, significantly reduce the size of sedimentation basin and drag for grey workload, for guaranteeing desulfuration efficiency, only need in sedimentation basin, to throw in the source and enrich low-cost lime, method is simple.

The detailed structure of this combined dust remover is provided by embodiment and accompanying drawing thereof.
