Description
Technical field
The utility model relates to a kind of heat transmission equipment of petroleum chemical industry, particularly a kind of bridging type double helix band wing deflection plate that improves heat exchange efficiency.
Background technology
At present, at petroleum chemical industry, the heat transmission equipment important role, wherein the performance of deflection plate is determining the heat exchange efficiency of heat transmission equipment, design a kind of Novel baffle, on the basis of double helix deflection plate, further optimize the structure of deflection plate, heat exchange efficiency is improved, and reduces the waste of resource.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of bridging type double helix band wing deflection plate is provided, and its structure is optimized, and to improve the heat exchange efficiency of heat exchanger, reduces the waste of resource.
Its technical scheme is: comprise deflection plate, lap-joint, housing, lap-joint at the top of housing arranges deflection plate, and the housing inner chamber is provided with the double helix heat exchange pipe, and deflection plate is provided with a plurality of nail wings, make fluid form turbulent flow, follow closely simultaneously the intensity that wing has also increased deflection plate; Adopt the connected mode of juxtaposition overlap joint between deflection plate, the double helix heat exchange pipe has stronger guide functions to shell fluid.
Above-mentioned nail wing is column structure.
The beneficial effects of the utility model are: strengthened the tube bank rigidity, the double helix heat exchange pipe has stronger guide functions to shell-side fluid simultaneously, in the situation that the fluid transmitting power allows further to improve the heat exchange efficiency of heat exchanger, has reduced the waste of resource.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is baffle arrangement schematic diagrames of the present utility model;
Accompanying drawing 3 is structural representations of double helix heat exchange pipe of the present utility model;
In upper figure: deflection plate 1, lap-joint 2, housing 3, nail wing 4, housing flow process 5, double helix heat exchange pipe 6.
The specific embodiment
1-3 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises deflection plate 1, lap-joint 2, housing 3, lap-joint 2 at the top of housing 3 arranges deflection plate 1, and housing 3 inner chambers are provided with double helix heat exchange pipe 6, and deflection plate 1 is provided with column nail wing, make fluid form turbulent flow, follow closely simultaneously the intensity that wing has also increased deflection plate; Adopt the connected mode of juxtaposition overlap joint between deflection plate 1,6 pairs of shell fluid of double helix heat exchange pipe have stronger guide functions, and 5 minutes two-way of housing flow process enter housing, flow along the mobile double helix that forms of deflection plate.
Column nail wing of the present utility model has destroyed the laminar flow zone on the deflection plate, makes fluid than just forming turbulent flow under low reynolds number, follows closely simultaneously the intensity that wing has also increased deflection plate.adopt the connected mode of juxtaposition overlap joint between deflection plate, reduced the short circuit phenomenon that two adjacent segmental baffle straight flanges intersect to form triangle space, guaranteed the raising of heat exchanger efficiency, the heat exchanger tube that has simultaneously same row or two rows passes two adjacent fanning strips, strengthened the tube bank rigidity, the structure of double helix heat exchange pipe has stronger guide functions to housing flow process 5 simultaneously, in the situation that the fluid transmitting power allows further to improve the heat exchange efficiency of heat exchanger, reduced central tube, under identical Reynolds number without central tube heat exchanger heat exchange efficiency higher than the central tube heat exchanger is arranged.
The utility model is applicable to the material-heat-exchanging that shell side has solid particle, because the spiral streamline makes particle be difficult for fouling on deflection plate.
