It is connected with outlet passageway, spray chamber is provided with blow vent with outlet passageway, and flue gas is entered into and through after sedimentation basin by inlet channel
Into spray chamber, finally discharged by outlet passageway；The spray top of chamber is provided with spray head.
Further, the blow vent is provided with water fender；The water fender extends stop of the flue gas in screen collector
Time, the precipitation of dust is increased, improve efficiency of dust collection.
Further, the inlet channel is externally provided with centrifugal blower；The centrifugal blower by from cyclone dust collectors discharge
Flue gas is blasted in screen collector.
Further, the cyclone dust collectors include air inlet pipe, cylinder, blast pipe and ash releasing tube；The air inlet pipe is located at rotation
Wind dust remover roof side wall, blast pipe is located at cyclone dust collectors top, and ash releasing tube is located at cyclone dust collectors bottom；By in economizer
Flue gas out enters cyclone dust collectors by air inlet pipe, and flue gas rotates inside cyclone dust collectors, by means of centrifugal force
Dust is separated from air-flow and wall is trapped in, then dust is fallen in the ash releasing tube of bottom by Action of Gravity Field, flue gas is most
Carry some minute dusts not being removed afterwards to discharge from top.
The beneficial effects of the utility model are：The utility model with the addition of water curtain dedusting on the basis of original boiler dusting
Device, dedusting is carried out using two-stage dust arrester to flue gas, cyclone dust collectors efficiently remove chalk dust removing in the case of increased one
Level dust removal device, flue gas in screen collector by the water-bath of sedimentation basin and the spray of spray head, can effectively will be tiny
Particulate is removed from flue gas, effectively increases the removal effect of dust, and causes finally discharged gas to reach the mark of regulation
It is accurate, hence it is evident that to improve atmospheric environment, reduce the infringement to health.

Specific embodiment
In order that the purpose of utility model, technical scheme and advantage are clearer, below in conjunction with the accompanying drawings to the utility model
It is further elaborated.
In the present embodiment, refering to Fig. 1-3, a kind of boiler dust removal system, including boiler, economizer, cyclone dust collectors and
Chimney, the economizer is arranged in boiler tail vertical gas pass, and cyclone dust collectors are located at after flue and flue gas is carried out tentatively
Dedusting；The boiler dust removal system also includes screen collector 1, and the screen collector 1 is located between cyclone dust collectors and chimney,
For carrying out two-stage dust removal to flue gas, the screen collector 1 includes admission line 2, spray chamber 3, outlet passageway 4 and sedimentation basin
5, the sedimentation basin 5 is connected with inlet channel 2, spray chamber 3 and outlet passageway 4, and spray chamber 3 is provided with ventilation with outlet passageway 4
Mouth 12, flue gas is entered into and through by inlet channel 2 and enter after sedimentation basin 5 spray chamber 3, is finally discharged by outlet passageway 4；It is described
The top of spray chamber 3 is provided with spray head 6, and spray head has two.
