Abstract
The utility model belongs to heat exchangers in the petrochemical industry, particularly relates to a spoiling device at a shell side inlet of a heat exchanger, which is used for fluid delivery medium tube side and comprises a shell side medium inlet flange connecting tube on a shell side casing. The spoiling device is characterized in that spoiling spiral blades rotating around a center of the flange connecting tube are mounted in the flange connecting tube at the shell side medium inlet. The spiral angle alpha of each spoiling spiral blade ranges from 20 degrees to 30 degrees, the screw pitch S ranges from 200mm to 400mm, and the length of each spiral blade ranges from 0.6S to 1.0S. The spoiling device is reasonable in design, simple and practical, flowing direction of a medium in the shell side can be changed, flushing area of the medium to a tube bundle can be greatly reduced, transverse stress load of the tube bundle can be reduced, vibration degree of the tube bundle can be reduced, and flow dead zone can be reduced effectively so that heat transfer efficiency is improved. Accordingly, the spoiling device has the advantages of energy saving, fine safety, convenience in operation and use, and the like.
Description
Technical field
The utility model belongs to the heat exchanger of petroleum chemical industry, particularly is used for carrying a kind of heat exchanger shell pass inlet disturbing flow device of fluid media (medium) tube side.
Background technology
As everyone knows, in chemical industry, often will be in carrying the tube side of fluid media (medium) the mounting heat exchanger shell side, its structure comprises that shell side shell, tube bank, shell side medium inlet flange are taken over and shell side media outlet flange is taken over; In the shell side shell, be distributed with the tube bank of forming by a plurality of pipes; Corresponding with the flow direction of carrying fluid media (medium), installing shell side medium inlet flange is taken on shell side shell one end end face, and installing shell side media outlet flange is taken on shell side shell other end bottom surface.When heat exchanger shell pass is worked, the shell side medium is taken over from shell side medium inlet flange and is flowed directly in the shell side shell, near the tube bank that this shell side medium just constantly vertically washes away the shell side inlet causes the part tube brakes, the medium that causes in the tube bank will leak, and will cause great safety hazard and economic loss to manufacturing factory.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and provides not only reasonable in design, and is simple and practical, can either change the flow direction of medium in shell side, significantly reduced medium again to restraining the area that vertically washes away; Can reduce tube bank and laterally be subjected to compressive load, reduce the vibrations degree of tube bank; Can effectively reduce flow dead again, thereby improve heat transfer efficiency; And having energy savings, security is good, and manipulates a kind of very easily heat exchanger shell pass inlet disturbing flow device.
The purpose of this utility model is to adopt following technical scheme to realize: described heat exchanger shell pass inlet disturbing flow device, comprise that the shell side medium inlet flange on the shell side shell takes over, it is characterized in that: in shell side medium inlet flange is taken over installing along this flange adapter center rotation formation, the disturbed flow type flight.
The pitch angle alpha will of described disturbed flow type flight is 20 °-30 °.
The pitch S of described disturbed flow type flight is 200mm-400mm.
The length L of described disturbed flow type flight is 0.6S～1.0S.
Because the shell side medium inlet flange in the utility model is taken over and has been installed the disturbed flow type flight, and this disturbed flow type flight is by heat exchanger shell pass inlet Flow Field Calculation, determine and adopt the dull and stereotyped flight that forms along the rotation of pipe connecting flange center in the utility model, just can change the flow direction of medium in shell side.Just significantly reduce fluid to restraining the area that vertically washes away, reduced tube bank and laterally be subjected to compressive load, can reduce the vibrations degree of tube bank.Simultaneously can effectively reduce flow dead, thereby improve heat transfer efficiency.Reduce simultaneously safety hazard again, improved the security and the energy energy savings that connect.
The comprehensive above technical scheme of being taked realizes the purpose of this utility model.
Compared with prior art, the utility model is not only reasonable in design, and is simple and practical, can either change the flow direction of medium in shell side, significantly reduced medium again to restraining the area that vertically washes away; Can reduce tube bank and laterally be subjected to compressive load, reduce the vibrations degree of tube bank; Can effectively reduce flow dead again, thereby improve heat transfer efficiency; And having energy savings, security is good, and manipulates advantages such as very convenient.
Description of drawings
The utility model has two width of cloth accompanying drawings.Wherein:
Accompanying drawing 1 is the main TV structure schematic diagram of specific embodiment of the utility model;
A place enlarged diagram among accompanying drawing 2 Fig. 1.
Among the figure: 1, shell side shell, 2, shell side medium inlet flange takes over, 3, the disturbed flow type flight.
The specific embodiment
Shown in Figure 1 is specific embodiment of the utility model, and it is a kind of heat exchanger shell pass inlet disturbing flow device of installing in the makers' conveying fluid media (medium) of certain Chemical Manufacture tube side; Its structure comprises: the shell side medium inlet flange on the shell side shell 1 takes over 2, it is characterized in that: shell side medium inlet flange take over installing in 2 along this flange adapter center rotation formation, disturbed flow type flight 3; The pitch angle alpha will of described disturbed flow type flight 3 is 25 °; The pitch S of described disturbed flow type flight 3 is 300mm; The length L of described disturbed flow type flight is 1.0S.
The above; it only is the preferable specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; all are familiar with those skilled in the art in the disclosed technical scope of the utility model, are equal to replace or change according to the technical solution of the utility model and design of the present utility model thereof all should be encompassed within the protection domain of the present utility model.
