The utility model discloses a kind of fluidized bed furnace, belong to sulfuric acid preparing technical field, solve traditional fluidized bed furnace boiling section space inadequate, thermal regulation is unstable and traditional bellows design is unreasonable, causes the problem of wind energy cloth inequality.Mainly comprise body of heater, described body of heater is provided with exhanst gas outlet and fuel inlet, slag-drip opening is provided with below body of heater, bottom of furnace body is also provided with blast pipe, and described blast pipe is connected with bellows, is provided with blast cap above described bellows, the cross section of described blast pipe is isosceles trapezoid shape, the rectangular trapezoidal shape of cross section of bellows, the cross section upper base included angle A size of described blast pipe is 101 °, and the corner dimension of the upper base included angle B of described bellows is 101 °.The utility model boiling section space is large, and bellows structure is ingenious, and wind energy is uniformly distributed, coal can Thorough combustion, hot blast system is stablized, and increase substantially burning of coal efficiency and significantly reduce cinder coking phenomenon, the utility model can be widely used in sulfuric acid manufacturing equipment technical field.
Description
Technical field
The utility model belongs to sulfuric acid manufacturing equipment technical field, specifically, particularly relates to a kind of fluidized bed furnace.
Background technology
Fluidized bed furnace is a kind of burning boiler, is a kind of new combustion technology that development in recent years is got up.When fluid flows through the static shot-like particle bed of material from below to up, if flow velocity exceedes certain limit, then bulk cargo layer starts to expand, wriggle and have mobility, and become false fluid state, this process is the fluidisation of bulk cargo layer.But in actual use, find that traditional fluidized bed furnace exists following defect gradually: 1. bottom the boiling section of fluidized bed furnace, centrum angle is 45 °, boiling section space is inadequate, and fluidized bed furnace does not seethe with excitement, and coal combustion is incomplete, and temperature is fluctuated, and thermal regulation is unstable.During temperature height, cause drier body to damage and increase the weight of, feed auger, blanking scraper-trough conveyer every half a year again fabrication and installation once, furnace roof is repaired once for 1 year.When temperature is low, the whole moisture of material drying is not up to standard, often exceeds 3%, larger on grinding machine impact; 2. the bellows wind of traditional fluidized bed furnace is not tangentially enter along air channel, causes wind energy skewness, the local coking that wind is large, and the place that wind is little is slowly burned, broken coal incomplete combustion.
Summary of the invention
The utility model discloses a kind of fluidized bed furnace, inadequate for solving traditional fluidized bed furnace boiling section space, thermal regulation is unstable and traditional bellows design is unreasonable, causes the problem of wind energy skewness.
The utility model is achieved through the following technical solutions:
A kind of fluidized bed furnace, comprise body of heater, described body of heater is provided with exhanst gas outlet and fuel inlet, is provided with slag-drip opening below body of heater, and bottom of furnace body is also provided with blast pipe, described blast pipe is connected with bellows, be provided with blast cap above described bellows, the cross section of described blast pipe is isosceles trapezoid shape, the rectangular trapezoidal shape of cross section of bellows, the cross section upper base included angle A size of described blast pipe is 101 °, and the corner dimension of the upper base included angle B of described bellows is 101 °.
Bottom the boiling section of described body of heater, the angular dimension of centrum angle C is 60 °.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model boiling section space is large, and coal can Thorough combustion, and thermal regulation is stablized, the parts long service life of fluidized bed furnace;
2. bellows structure of the present utility model is ingenious, and wind energy is uniformly distributed, and seethes with excitement effective, increases substantially burning of coal efficiency and significantly reduces cinder coking phenomenon;
3. the utility model structural design is simple, can be widely used in sulfuric acid manufacturing equipment technical field.
Accompanying drawing explanation
Accompanying drawing is the utility model structural representation.
In figure: 1. body of heater; 2. exhanst gas outlet; 3. fuel inlet; 4. slag-drip opening; 5. blast pipe; 6. bellows; 7. blast cap.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of fluidized bed furnace, comprise body of heater 1, described body of heater 1 is provided with exhanst gas outlet 2 and fuel inlet 3, is provided with slag-drip opening 4 below body of heater 1, is also provided with blast pipe 5 bottom body of heater 1, described blast pipe 5 is connected with bellows 6, be provided with blast cap 7 above described bellows 6, the cross section of described blast pipe 5 is isosceles trapezoid shape, the rectangular trapezoidal shape of cross section of bellows 6, the cross section upper base included angle A size of described blast pipe 5 is 101 °, and the corner dimension of the upper base included angle B of described bellows 6 is 101 °.
Bottom the boiling section of described body of heater 1, the angular dimension of centrum angle C is 60 °.
Bottom the boiling section of body of heater 1, the angular dimension of centrum angle C is 60 °, and to ensure the Thorough combustion of coal, heat discharges completely, reduces the wall built-up of coal, reaches the object reducing hear rate.
The cross section of blast pipe 5 is isosceles trapezoid shape, the rectangular trapezoidal shape of cross section of bellows 6, and the cross section upper base included angle A size of described blast pipe 5 is 101 °, and the corner dimension of the upper base included angle B of described bellows 6 is 101 °.Wind enters in bellows 6 by square fresh air inlet, then tangentially blows to blast cap 7 equably, and wind energy is evenly distributed.In the utility model body of heater 1, spread fine sand, open blower fan, sand grains can seethe with excitement equably on burner hearth, and when air door of fan is opened to 50%, the fine sand in body of heater 1 is just blown to 1.5-1.8m high by boiling, reaches the boiling effect of expection.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
