Description
Technical field
The utility model relates to a kind of chimney, particularly, relates to a kind of chimney that can control deflection.
Background technology
General heat and power plant of China all can use chimney, by the fume emission after fuel combustion in air, because the residing position of chimney is higher, segmentation chimney can be vacillated now to the left, now to the right under the effect of upper air current, and under the high-level lateral airflow effect of segmentation chimney, easily produces the distortion of large and difficult control.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of chimney that can control deflection.
The technical scheme in the invention for solving the above technical problem is:
A kind of chimney is provided, comprise the independently chimney unit that several are socketed mutually, described chimney unit is that two ends are compared with little and middle larger hollow structure, chimney unit comprises inner sleeve end arbitrarily, overcoat end and connect the interlude of described inner sleeve end and overcoat end, the inner sleeve end of arbitrary chimney unit is socketed in the overcoat end of its adjacent chimney unit, the external diameter of described inner sleeve end is less than the internal diameter of described overcoat end substantially, gap between inner sleeve end and the overcoat end socket-connecting by control, control the relative motion of two adjacent chimney unit, and then the deflection of control chimney.
Further, the bending curvature of described inner sleeve end is greater than the bending curvature of described overcoat end.
Further, the gap between inner sleeve end and the overcoat end socket-connecting is to be no more than 0.08 times of inner sleeve end length.
Further, described interlude and described inner sleeve end and overcoat end rounding off, and the internal diameter of described interlude is greater than the external diameter of inner sleeve end and overcoat end.
Further, described chimney comprises a pedestal being connected with chimney unit, is provided with a passage for flue gas circulation in described pedestal, and one end of described passage is connected with described chimney unit.
Further, the internal diameter of described inner sleeve end is greater than the diameter of the passage of described pedestal.
To sum up, the beneficial effects of the utility model are: the chimney unit independently separately of mutual socket is set, by controlling the motion deviation oscillation between two adjacent chimney unit, thereby controls the deflection of whole chimney.
Brief description of the drawings
Fig. 1 is the structural representation of chimney shown in the present embodiment preferred embodiment;
Fig. 2 is the local enlarged diagram in Fig. 1;
Mark and corresponding parts title in accompanying drawing: chimney 100, chimney unit 10, pedestal 102, inner sleeve end 11, overcoat end 12, interlude 13.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but embodiment of the present utility model is not limited to this.
Embodiment 1
Refer to Fig. 1 and Fig. 2, the chimney 100 shown in the utility model preferred embodiment, is mainly independently mutually socketed and forms in chimney unit 10 by several.
Described chimney 100 comprises a pedestal 102 being fixedly connected with the chimney unit of the bottom, described pedestal 102 carries described some chimneys unit 10 and is fixed on ground, in described pedestal 102, be provided with a passage (not shown) for flue gas circulation, one end of described passage is connected with described chimney unit 10, flue gas enters described chimney unit 10 by described pedestal 102, is expelled to high aerial.
10Wei two ends, described chimney unit are compared with little and middle larger hollow structure, chimney unit 10 comprises inner sleeve end 11, overcoat end 12 and connects the interlude 13 of described inner sleeve end 11 and overcoat end 12 arbitrarily, the external diameter of described inner sleeve end 11 is less than the internal diameter of described overcoat end 12 substantially, namely, the gap between inner sleeve end 12 and the overcoat end 11 socket-connecting is less.The internal diameter of described inner sleeve end 11 is greater than the diameter of the passage of described pedestal 102.The inner sleeve end 11 of arbitrary chimney unit 10 is socketed in the overcoat end 12 of its adjacent chimney unit 10, and the bending curvature of described inner sleeve end 11 is more basically identical or bigger than the bending curvature of described overcoat end 12, more preferably, the bending curvature of described inner sleeve end 11 is slightly larger than the bending curvature of described overcoat end 12.
Equal rounding off between described interlude 13 and described inner sleeve end 11 and overcoat end 12, and in the present embodiment, the internal diameter of described interlude 13 is all greater than the external diameter of inner sleeve end 11 and overcoat end 12, and the smoothness that is conducive to flue dust is current.
High-altitude is distinguished and admirable, and what chimney 100 was impacted is mainly side direction wind, when side direction wind is to described chimney unit 10 time, the chimney unit of any chimney unit 10 relative its socket is along with wind direction moves, in the time moving to a upper chimney and next chimney and offset, concrete as, the inwall of the sidewall both sides of the inner sleeve end 11 of a upper chimney and the overcoat end 12 of next chimney offsets respectively, thereby a upper chimney is with respect to the motion of next chimney shown in limiting, and then limit the deflection of whole chimney 100.And those skilled in the art is according to the selection in the gap between inner sleeve end 11 and overcoat end 12 to socket-connecting, can controls the relative motion between adjacent two chimney unit, thereby can control the degree of crook of whole chimney.In the present embodiment, select the gap between the inner sleeve end 11 and the overcoat end 12 that socket-connect as far as possible little, this gap optimal selection is to be no more than 0.08 times of inner sleeve end 11 length.
In the utility model, about the description in upper inferior orientation is consistent with the expression mode in accompanying drawing, and be also consistent about upper and lower description in actual use with chimney, that is, contrast, is more close under being on ground between two, be more close in sky for upper.
To sum up, chimney 100 described in the utility model, arranges the chimney unit 10 independently separately of mutual socket, by controlling the motion deviation oscillation between two adjacent chimney unit 10, thereby controls the deflection of whole chimney 100.
As mentioned above, can realize preferably the utility model.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; according to technical spirit of the present utility model; within spirit of the present utility model and principle; any simple amendment that above embodiment is done, be equal to and replace and improve etc., within all still belonging to the protection domain of technical solutions of the utility model.
