Abstract
The utility model discloses a double-cylinder chimney, which comprises an external cylinder and two internal cylinders, wherein the two internal cylinders are arranged in parallel in the external cylinder with circular cross section; and the cross section of each internal cylinder is elliptic or oblate. The external cylinder of the double-cylinder chimney is small in diameter.
Description
Technical field
The utility model relates to a kind of chimney, the bitubular chimney that a kind of specifically power plant uses.
Background technology
Along with the development need of national economy, chimney obtains application more and more widely as a kind of important structure in engineering constructions such as power plant.In the industry type building of China, be main generally at present with the telescopic chimney of steel concrete.
At present domestic is main with single sleeve chimney mainly, but along with the change of unit capacity is big, the diameter of smoke evacuation inner core begins to increase, and is unfavorable for the construction and the operation of chimney internal cylinder.The multitube Steel Inner Core of Chimney is present general in the world a kind of chimney of electric plant pattern; Its major advantage is: flue gas flow rate is stable; Flue Gas Diffusion is effective, is convenient to Maintenance and Repair, and structure temperature stress is little; Can avoid the steel concrete urceolus crack and corrosion to occur, improve the overall durability ability of chimney of electric plant.In recent years, the total trend of large-size thermal power plant is to adopt this chimney.
Traditional telescopic chimney emission inner core is circular, and under the big situation of unit capacity change at present, even adopted two-tube chimney, the diameter of smoke evacuation inner core is still very big, and this just causes the diameter of concrete urceolus bigger, has increased construction investment, and is also not attractive in appearance.Some processing method is the concrete urceolus to be treated to oblate or oval, does not fundamentally change the occupation of land problem, causes profiled-cross-section on the contrary, has increased front face area, is unfavorable for structure stress, also construction is caused difficulty, and profile is not attractive in appearance yet simultaneously.
The utility model content
The utility model technical issues that need to address provide the little bitubular chimney of a kind of urceolus diameter.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of bitubular chimney comprises urceolus and two inner cores, and said two inner cores are arranged side by side in cross section in the circular urceolus, the cross section ovalize of inner core or long oblate.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The inner core cross section is oval or long oblate structure, and the diameter of chimney urceolus is reduced, and has not only saved the occupation of land of chimney, and the chimney front face area is reduced, and more helps structure stress, also makes chimney have better outward appearance simultaneously.
Description of drawings
Fig. 1 is the structural representation of bitubular chimney;
Fig. 2 is the another kind of structural representation of bitubular chimney
Wherein, 1, urceolus, 2, inner core.
The specific embodiment
Below in conjunction with description of drawings the utility model is explained further details:
As shown in the figure, bitubular chimney comprises urceolus and two inner cores; Said two inner cores are identical, are arranged side by side in the urceolus, and the cross section ovalize of inner core; Also can be long oblate; The cross section of urceolus is circular, and certain spacing is all arranged between inner core and inner core, inner core and the urceolus, to guarantee the normal repairing of chimney.
Claims (1)
1. a bitubular chimney comprises urceolus and two inner cores, it is characterized in that: said two inner cores are arranged side by side in cross section in the circular urceolus, the cross section ovalize of inner core or long oblate.
