Abstract
The utility model relates to the technical field of thermal power generation, in particular to a novel material collecting device of a circulating fluidized bed boiler, which comprises a horizontal flue, a center cylinder, a conical cylinder and a material pipe. The novel material collecting device of the novel circulating fluidized bed boiler is characterized in that an inlet prismatic edge of the horizontal flue is 1140 mm, and an outlet prismatic edge is 820 mm; and the center cylinder is provided with a large cylinder at the upper part and a small cylinder at the lower part, which are connected by a circular truncated cone at the middle part, wherein the large cylinder has the bottom surface diameter of Phi 1500 mm and the height of 900 mm, the lower cylinder has the bottom surface diameter of Phi 1350 mm and the height of 1280 mm, and the circular truncated cone has the height of 200 mm. The novel material collecting device has the benefits that the smoke flowing rate can be increased, a smoke separation path is increased, and further the material separation capability is enhanced, so that the material can be fully recovered, and the economic benefits are improved.
Description
Technical field
The utility model relates to the thermal power generating technology field, a kind of specifically device of New Cycle fluidized-bed combustion boiler material collection.
Background technology
At present, known CFBB material collection device is by horizontal flue, central tube, and conically shaped, materail tube are formed; The one side tangential, top of conically shaped is connected with horizontal flue; Central tube is equipped with at the top, and the bottom is connected with materail tube, and horizontal flue is that import is big; Go out young prismoid, import prismatic length of side 1400mm, outlet length of side 890mm; Central tube is a cylinder, and long 1980mm, bottom surface diameter are Ф 1500mm.Use this gathering-device, flue gas flow rate is slow, and the feed separation ability is low, and material recovery rate is relatively poor.
Summary of the invention
The utility model purpose is to overcome above deficiency, and a kind of device of New Cycle fluidized-bed combustion boiler material collection is provided, and uses this device can accelerate the flow velocity of flue gas, strengthens the feed separation ability, and material is reclaimed fully, increases economic efficiency.
The utility model solves the used technical scheme of its technical problem: a kind of device of New Cycle fluidized-bed combustion boiler material collection, form by horizontal flue, central tube, conically shaped and materail tube, and it is characterized in that: the horizontal flue import prismatic length of side is 1140mm; The outlet prismatic length of side is 820mm; Be large cylinder on the central tube, be small cylinder down, the centre is connected by Rotary-table; Large cylinder bottom surface diameter is Ф 1500mm; High for cylinder bottom surface diameter under the 900mm is Ф 1350mm, height is 1280mm, round platform height 200mm.
The beneficial effect of the utility model is: can accelerate the flow velocity of flue gas, increase the separation path of flue gas, thereby the separating power of strength imparting material reclaimed material fully, increases economic efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1. horizontal flues among the figure, 2. central tube, 3. conically shaped, 4. materail tube.
The specific embodiment
A kind of device of New Cycle fluidized-bed combustion boiler material collection is made up of horizontal flue 1, central tube 2, conically shaped 3 and materail tube 4, it is characterized in that: the horizontal flue 1 import prismatic length of side is 1140mm; The outlet prismatic length of side is 820mm, is large cylinder on the central tube 2, is small cylinder down; Middle large cylinder bottom surface diameter is Ф 1500mm by the Rotary-table connection, and high is that cylinder bottom surface diameter is Ф 1350mm under the 900mm; Height is 1280mm, round platform height 200mm.
During work; The flue gas of burning in circulating fluid bed boiler ergastic mateiral material gets into conically shaped 3 from horizontal flue 1 tangential; Under deadweight and action of centrifugal force; Discharge from central tube 2 because the difference of material density, light flue gas rise, heavy material sinks to collecting back burning in circulating fluid bed boiler by materail tube 4.Because this novel material gathering-device has reduced the area of horizontal flue 1 cross section; Central tube 2 overall height that extended simultaneously and reduced central tube 2 intake areas; Thereby the flow velocity of flue gas and the disengaging time of material have been increased; Strengthened the separating power of material, material is reclaimed fully, increased economic efficiency.
