Abstract
The utility model discloses a smoke prevention burner, comprising a horn shape burning hopper (2) which is positioned in a shell body (1) and a spiral conveying pipe (3) which is connected with the side wall of the burning hopper (2). The outer wall of the conveying pipe (3) is communicated with a hopper (4). One end of the spiral shaft (6) which is arranged in the feed pipe (3) and is provided with the spiral leaves (5) is connected with a power device. The air conveying pipe (7) of the air feeder is connected with the shell body (1). The upper part of the burning hopper (2) is an upper burning hopper which is communicated with the burning chamber of the boiler, and the side wall of the upper burning hopper is distributed with the air vents (8). The lower part of the burning hopper (2) is a lower burning hopper, the bottom of the lower burning hopper is sealed, and the side wall of the lower burning hopper is communicated with the conveying pipe (3) and an air inlet (9). The other end of the spiral shaft (6) transversely penetrates through the lower burning hopper and is supported on the bearing seat (10) of the exterior of the burning hopper (2).
Description
Technical field:
The utility model is relevant with the combustor of coal-burning boiler.
Background technology:
The burning bucket of the vertical auger fire grate combustor of existing coal-burning boiler is up big and down small loudspeaker tubular, the upper end is connected with the cylindrical shape burning tube of sidewall sealing and communicates with boiler furnace, the bottom is connected with a vertical axes, and vertical axes is positioned at the part of burning bucket and is fixed with vertical screw auger.Burn the uniform air vent in the sidewall whole body of bucket, and be connected with flat spin auger discharging opening.During work, fire coal adds from coal bunker, entering porous through the flat spin auger burns in the bucket, vertical auger burns the coal jacking to burning tube, the hole that wind burns bucket bottom and sidewall from porous enters a top burning tube wife coal combustion, because porous fire grate floor coal lifted on the vertical auger, the hole that a large amount of air are crossed on the spiral leaf of vertical auger from the bottom rising warp let-off is delivered to the coal of top, to guarantee the amount of supplied air of coal combustion.Because not in the same way auger conveyor of two covers is arranged, and complex structure is made and the maintenance cost height, it is also high to consume energy.The coal that burns in the tube can not obtain the air supply from sidewall, and it is insufficient to burn.
The content of utility model:
The purpose of this utility model provides a kind of simple in structure, and low cost of manufacture is easy to maintenance, and it is low to consume energy, the smoke elimination burner of sufficient combustion.
The utility model is achieved in that
The utility model smoke elimination burner, comprise the tubaeform burning bucket 2 that is positioned at housing 1, the screw conveying pipe 3 that is connected with burning bucket 2 sidewalls, the outer wall of feed pipe 3 is communicated with hopper 4, an end of the helical axis 6 of band spiral leaf 5 is connected with power set in the feed pipe 3, the ajutage 7 of pressure fan is connected with housing 1, the top of burning bucket 2 is communicated with the boiler combustion district, bucket is burnt in going up of the uniform air vent 8 of sidewall, the lower part is a bottom lock, the following burning bucket that sidewall is communicated with feed pipe 3 and air inlet 9, the other end of helical axis 6 cross down the burning bucket and are supported on the bearing block 10 that burns outside the bucket 2.
Housing 1 is by cylindrical shape wallboard 11, the base plate 12 that is connected with its lower end, form with its upper end flange connecting panel 13, the interior circle of panel 13 is connected with the big end of frustum tubular support bucket 14, flange panel 13 is connected with the boiler flange, is connected with some uniform setting airducts 15 on it, the air compartments that logical housing 1 inwall in the lower end of airduct 15 and burning bucket 2 constitute, logical top, combustion zone, upper end, air compartment is connected with the pressure fan air outlet by air inlet 9.
The utility model has a cover conveying worm to finish coal-fired adding and burn stirring and lifting operation coal-fired in the bucket.Because laterally the terminal point of feed screw is burning the bucket sidewall down, the coal of destination county constantly protuberance is lifted to and burns bucket and burn the air that bucket sidewall fresh air inlet sends into and mix, and owing to last burning bucket uniform air vent all around, air is in liberal supply, sufficient combustion.
The utility model is simple in structure, and is easy to manufacture, with low cost, easy to maintenance, and power consumption is few.
