Abstract
The utility model discloses a double-barreled chimney inlet flue structure of a thermal power plant. The double-barreled chimney inlet flue structure comprises a straight pipe section, and is characterized in that the straight pipe section is connected with an elbow, wherein the elbow is connected with a transition section; the transition section is connected with a non-metallic compensator; a fan-shaped guide vane is arranged in the elbow. In the utility model, the double-barreled chimney inlet flue structure reduces a tee-joint section, a hole enlargement section and a larger straight pipe section, and is directly connected with a chimney vertical pipe section through the elbow in a transition manner. In the way, the structure not only optimizes the air flue flow field and reduces the systemic resistance, but also greatly shortens the distance between peripheral equipment and the chimney; according to a wet method desulfuration technique, at least 10 m distance can be reduced; the double-barreled chimney inlet flue structure can substitute the original combined irregular element structure, fails to increase the occupied space, reduces vibration and resistance of the flue by internally increasing the fan-shaped guide vane for rectifying medium flow in the flue, and is low in energy consumption, efficient in the system, and energy-saving.
Description
Technical field
The utility model belongs to the optimization of air and gas system cigarette air channel, power plant shaped piece, resistance optimization technology, especially relates to chimney gas approach elbow structure form in the air and gas system of thermal power plant.
Background technology
In the component structural of cigarette air channel, current thermal power plant, chimney gas approach parts major part comprises the combining structure of the shaped pieces such as straight length, extension diameter section, threeway, it is because the reasons such as combined special-shaped structure cause gas movement disorder, resistance large, cause air and gas system resistance higher, blower fan (air-introduced machine) motor selection is excessive, and operating cost and operating cost are higher.Because flue entrance parts are more, flue path is longer simultaneously, and floor space is larger.
Utility model content
The utility model, according to cigarette original chimney gas approach arrangement and media flow direction, is optimized the structure of chimney entrance shaped piece comprehensively, form a kind of structural safety, consume energy little, system high efficiency, energy-conservation a kind of chimney entrance air channel structure form.
For achieving the above object, the utility model provides a kind of thermal power plant two-tube chimney gas approach structure, comprises straight length, it is characterized in that: straight length connects an elbow, elbow connects a changeover portion, and changeover portion connects non-metal compensator, establishes fan-shaped guide vane in elbow.
The utility model reduces threeway section, extension diameter section and longer straight length, by one group of elbow transition, be directly connected with the vertical pipeline section of chimney, this structure has not only been optimized the flow field in air channel and has been lowered SR, shortened greatly the distance between external equipment and chimney simultaneously, according to wet desulfurizing process, can reduce at least 10m distance, replace the structure of original combined special-shaped, do not increase and take up an area space, by inside, increase fan-shaped guide vane, for flowing of rectification road in-vivo medium, reduce vibration and the resistance of cigarette air channel body, consume energy little, system high efficiency, energy-conservation.
