Abstract
A baffle plate with profiled orifices, comprising a baffle plate; wherein, the baffle plate is a round disk, and flow holes communicating to the pipe orifices are arranged beside the baffle plate and form profiled orifices with the pipe orifices. The utility model has the following advantages: the utility model has a high heat-transfer coefficient, and can enhance heat transfer efficiency inside and outside of the tube; the overall heat transfer coefficient is 20 swung dash 30% higher than that of any ordinary segmental baffle; the utility model can reduce fluid induced vibrations and prolong service life of the product; the utility model has high anti-scaling capability and can be widely used for a variety of media and structure forms.
Description
Technical field
The utility model belongs to a kind of deflection plate of shell-and-tube heat exchanger, particularly a kind of deflection plate that has profiled holes
Background technology
In recent years, along with extensive, further investigation to shell-and-tube heat exchanger augmentation of heat transfer technology, shell-and-tube heat exchanger has had bigger development and improvement, its structure is also from the original traditional segmental baffle and the combining structure of plain tube, develop into the nowadays advanced shell side supporting structure and the combining structure of intensify heat transfer pipe, novel shell side longitudinal stream shell-and-tube heat exchanger is exactly an one.Shell side longitudinal stream heat exchanger is meant the effect by the novel tubulation supporting structure of heat exchanger shell pass, makes fluid main flow in the heat exchanger shell pass present the shell-and-tube heat exchanger of vertical flow regime.Versions such as the now existing rod baffle of shell side longitudinal stream structure, helical baffles, this longitudinal stream structure is compared with traditional segmental baffle structure, and the shell-side fluid flow velocity has been improved in the dead band of not conducting heat, strengthened the shell side heat transfer, but augmentation of heat transfer needs also further to improve in the pipe.
The utility model content
The purpose of this utility model provides a kind of deflection plate that has profiled holes, has both solved augmentation of heat transfer in the pipe, the augmentation of heat transfer effect that also improves shell side simultaneously.
The purpose of this utility model is achieved by the following technical solution: it comprises deflection plate, it is characterized in that: deflection plate is a full circle shape, and the opening in that the pore side setting of deflection plate communicates constitutes profiled holes with pore.
The utility model is assembled in rectangular opening plate fluted tube, the corrugated tube heat exchanger, forms a kind of novel longitudinal stream structure, its enhanced heat transfer mechanism mainly is because the jet action that the opening passage that orifice plate and heat exchange tube wall constitute forms.Fluid from opening penetrates can form eddy current soon after leaving the aperture.Under the influence of eddy current, the local mixing will take place with surrounding liquid in jet, and with a part of fluid removal, thereby jet is constantly increased along journey.So under lower Reynolds number, shell-side fluid just can reach local turbulence.Simultaneously, in the adherent jet in plane, rate of flow of fluid height in the perforation has washed away with attenuate the boundary layer of heat transfer liquid film, reaches turbulence state, makes the film heat transfer coefficient of heat exchanger tube improve greatly, and makes heat exchanger tube less scaling, has reached augmentation of heat transfer.In addition, because orifice plate is circular, do not have dead band and bypass leakage current, heat transfer area can obtain to make full use of, and has significantly improved heat transfer efficiency.
Advantage of the present utility model: 1, heat transfer coefficient height, simultaneously in the enhanced tube and the outer heat transfer efficiency of pipe, overall heat-transfer coefficient can improve 20%～30% than common segmental baffle board heat exchangers; 2, reduce the flow-induced vibration, prolong product service life; 3, resistive connection dirt ability is strong; 4, of many uses, be applicable to various media and various version.
Description of drawings
Fig. 1 is embodiment 1 structural representation of the present utility model.
Fig. 2 is embodiment 2 structural representations of the present utility model.
The specific embodiment
See Fig. 1, embodiment 1 structure is as follows: deflection plate is a full circle shape, mills logically at the side of deflection plate pore 1, and promptly opening 2 rectangular holes constitute profiled holes with pore 1.Dotted line among the figure is a heat exchanger tube 3.
See Fig. 2, embodiment 2 structures are as follows: deflection plate is a full circle shape, is milled with opening 2 around each deflection plate pore 1, and opening 2 constitutes the plum blossom hole shape with pore 1, and opening is adherent to be evenly distributed on around the heat exchanger tube.Dotted line among the figure is a heat exchanger tube 3.
The heat exchanger tube 3 that the utility model is installed can adopt groove line heat exchanger tube, corrugated tube heat exchanger.Be installed in the heat exchanger, the opening position difference of adjacent baffle flows shell-side fluid and presents vertical baffling, realizes the augmentation of heat transfer of longitudinal stream heat exchanger.
The utility model is applicable to all kinds of heat transmission equipments of every field such as petrochemical industry, electric power, heat supply, chemical fertilizer oil refining.
