Abstract
The utility model provides a screw centrifugal duster for boiler, which belongs to the technical field of duster and consists of a centrifugal barrel, a screw rod, a dust storing machine and an exhaust pipe. The screw rod is arranged in the centrifugal barrel, with a rotating sheet connected with the inner wall of the centrifugal barrel; the dust storing machine surrounds the centrifugal barrel whose barrel wall is opened with a through hole that is connected with the centrifugal barrel and the dust storing barrel; moreover, the bottom of the centrifugal barrel is communicated with the exhaust pipe. When in use, the top end of the centrifugal barrel is connected with the smoke outtake channel of the boiler, and the dust in the boiler is transported into the centrifugal barrel by the smoke outtake channel through an draft fan; after entering the centrifugal barrel, the dust rotates downwards around the screw rod, and the comparatively heavy dust particles are threw to the wall of the centrifugal barrel in effect of centrifugal force and then enter the dust storing machine through the through hole; after that, the smoke enters the exhaust pipe and discharged. Having a simple structure, the utility model can effectively clear the small particles that are not burned out in the smoke, thereby preventing the air pollution caused by burning solid fuel.
Description
Technical field:
The utility model belongs to the cleaner technical field, is a kind of deduster that is used for solid fuel fired boiler.
Background technology:
Existing solid fuel fired boiler is a main fuel with coal and timber, and the granule that some can not after-flame during burning discharges out of the furnace with flue gas, and environment is polluted, and the chimney on the boiler can reduce the discharge rate of particle, but effect is undesirable.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind of deduster that can remove grit in the boiler smoke effectively.
The scheme of the utility model technical solution problem is to adopt centrifugal barrel, screw rod, dust collector and smoke evacuation tracheae to constitute the spiral centrifugal deduster, screw rod is in centrifugal barrel, blade on the screw rod is connected on the centrifugal barrel inwall, dust collector surrounds centrifugal barrel, have through hole on the bucket wall of centrifugal barrel, through hole is communicated with centrifugal barrel and dust collector, and the bottom of centrifugal barrel is communicated with the smoke evacuation tracheae.Top with centrifugal barrel during use is connected with the smoke outlet flue of boiler, flue dust in the boiler is sent into centrifugal barrel by air-introduced machine by smoke outlet flue, flue dust enters the centrifugal barrel back wall and rotates around screw rod and move downward, centrifugal force is thrown to the centrifugal barrel wall with heavier grit, enter in the dust collector through through hole, flue gas enters the smoke evacuation tracheae and is discharged.
The utility model can be removed in the flue gas effectively not by the granule of after-flame, and is simple in structure, avoided because the air pollution that buring solid fuel causes.
Description of drawings:
Fig. 1 is the utility model partial sectional view;
Fig. 2 is the utility model A-A cutaway view.
The specific embodiment:
The utility model is made of centrifugal barrel 1, screw rod 2, dust collector 5 and smoke evacuation tracheae 6, screw rod 2 is in centrifugal barrel 1, blade 3 on the screw rod 2 is connected on centrifugal barrel 1 inwall, dust collector 5 surrounds centrifugal barrel 1, have through hole 4 on the bucket wall of centrifugal barrel 1, through hole 4 is communicated with centrifugal barrel 1 and dust collector 5, and the bottom of centrifugal barrel 1 is communicated with smoke evacuation tracheae 6.Top with centrifugal barrel 1 during use is connected with the smoke outlet flue 7 of boiler.
