Abstract
The utility model relates to a smoke removing and dusting apparatus of a vertical coal-combusting boiler, belonging to the field of a boiler, and the utility model is designed in the view of the existing vertical coal-combusting boiler having poor smoke removing and dusting effect and incomplete combustion. Circular boiler arches are mainly arranged above a boiler chamber of the vertical coal-combusting boiler and below a smoke outlet window, a plurality of small holes are arranged on the boiler arches, secondary air pipes in straight and horizontal arrangement are arranged above the circular boiler arches and below the smoke outlet window and are positioned at the central part of the boiler chamber, and both sides of the secondary air pipes are provided with a plurality of air outlet holes. The utility model achieves the smoke removing and dusting goal through the circular boiler arches and the secondary air pipes and strengthens the combustion of coal, and the utility model can be applied to various vertical coal-combusting boilers.
Description
The utility model belongs to the device for eliminating smoke and dust that is used for the vertical fire coal boiler in the field of boilers.
The flame of vertical fire coal boiler and flue gas, its flow process enters atmosphere by burner hearth via convection bank, chimney.Straight because the flow process of flame and flue gas is short, will there be a large amount of unburnt fuel gas and solid particle to enter atmosphere, environment is caused severe contamination.Chinese patent " vertical fire coal boiler combustion dust arrester " (patent No. 98209561.9) provides a kind of vertical fire coal boiler smoke abatement dust arrester, solved the smoke abatement and dust control problem of vertical fire coal boiler preferably, but need to add oxygen, use inconvenience, expense is higher.
The utility model is developed at the deficiencies in the prior art, has to eliminate smoke and the high vertical fire coal boiler smoke abatement dust arrester of good dedusting effect efficiency of combustion.
The utility model is realized by following measure.This device is made up of burner hearth, fire grate, garden type chimney arch, secondary air channel, blower fan.It is characterized in that: above burner hearth, the below of smoke outlet window is provided with garden shape chimney arch, is furnished with some apertures on the shape chimney arch of garden.Above the shape chimney arch of garden, the below of smoke outlet window is provided with the secondary air channel that the burner hearth core was inserted and passed through to level, and some exhaust vents are opened in the airduct both sides.
When boiler normally moved, coal was in the burner hearth internal combustion, and red-hot garden shape chimney arch has invigoration effect to burning of coal, sufficient combustion.Flame is when passing through some apertures of garden shape chimney arch, flame there is stirring action, unburnt fuel gas and solid particle are under the effect of red-hot aperture, help further after-flame, and flame is all practised in the furnace profile distribution, when flame continues upwards to flow, horizontally disposed and pass the secondary air channel of burner hearth core, when fan starting, secondary wind from its airduct both sides exhaust vent ejection, penetrate flame with all practising and mix, sufficient oxygen is provided, make the further after-flame of unburnt fuel gas and solid particle with it.Because straight secondary air channel is horizontally disposed and pass the burner hearth core, it is little to have solved general blower fan Yang Cheng, is difficult to penetrate flame, does not reach secondary wind role problem.Secondary air channel has been avoided the direct radiation of flame kernel under the protection of garden shape chimney arch, enough wind is arranged in cooling again; secondary air channel is safe and reliable, and maintenance is convenient, and flame separates with flue dust by the secondary smoke elimination of this device; reach the purpose of smoke abatement and dust control, obtained splendid effect.
The utility model has the advantages that: strengthened burning of coal, improved efficiency of combustion, enlarged the coal adaptability of boiler, splendid smoke elimination and dust removing effects are arranged again, and this apparatus structure is simple, uses easy to maintenance, operating cost is low, can be applicable in the various vertical fire coal boilers.
Accompanying drawing is a structural representation of the present utility model, and (1) is smoke outlet window among the figure; (2) be secondary air channel; (3) be blower fan; (4) be garden shape chimney arch; (5) be burner hearth; (6) be fire grate; (7) be boiler body.Arrow upwards be flame flow to, left and right sides arrow be secondary distinguished and admirable to.
Below in conjunction with a description of drawings embodiment of the present utility model.Device for eliminating smoke and dust is in the top of burner hearth (5), and the below of smoke outlet window (1) is provided with garden shape chimney arch (4), opens some apertures on the garden shape chimney arch (4).The top of garden shape chimney arch (4), the below of smoke outlet window (1) is provided with straight secondary air channel (2), and some exhaust vents are opened in the both sides of secondary air channel (2), and horizontally disposed by burner hearth (5) core.When boiler normally moved, the coal in the burner hearth (5) was burning, and is subjected to the radiation effects of red-hot garden shape chimney arch (4), has strengthened burning of coal and after-flame, has improved efficiency of combustion.When thermal-flame is gone up some red-hot apertures by garden shape chimney arch (4), have and eliminate smoke and the dedusting effect.When flame continues upwards to flow, be contained in secondary air channel (2) by burner hearth (5) core, when blower fan (3) started, from the secondary wind of airduct (2) both sides exhaust vent ejection, vertical directive flame made unburnt fuel gas and solid particle after-flame once more.
Claims (1)
1. the device for eliminating smoke and dust of a vertical fire coal boiler, form by burner hearth, fire grate, garden shape chimney arch, secondary air channel, blower fan, it is characterized in that: in burner hearth (5) top, smoke outlet window (1) below, be provided with garden shape chimney arch (4), chimney arch has some apertures on (4); In garden shape chimney arch (4) top, smoke outlet window (1) below, and partly be provided with secondary air channel straight, level (2) at the center of burner hearth (5), there are some exhaust vents the both sides of airduct (2).
