Abstract
The utility model relates to a multi-range shell and tube heat exchanger, which is suitable to the chemical process and other process equipment still requiring cold/heat exchange. The utility model overcomes two defects existing in the prior art that the stress and heating in the radical direction of the tube sheet on the flat surface parallel to the sealing face of the tube sheet are not uniform because of unreasonable structure and the flanges of the tube sheet and a tube box are difficult to seal, and the utility model improves the cold/heat exchange effect and the service quality. Meanwhile, the utility model is easy to manufacture and assemble compared with the exiting heat exchangers, the working procedure and processing equipment are reduced, and the assembly and service quality can be ensured.
Description
A kind of petrochemical technology process or other process equipment that conducts heat of being used for.
At present, the multipass shell-and-tube heat exchanger of common use is to be used to the common and requisite non-standard equipment that conducts heat.Now the multipass formula heat exchanger of Shi Yonging gets used to being provided with flat pass partition in conduit box, with the tube side separated into two parts or more than two-part version.In order to reach service property (quality) and to satisfy the needs of this structural design, the processing technology of this heat exchanger is with regard to more complicated and difficulty, thereby makes processing cost relatively more expensive.Also there are two shortcomings that are difficult for overcoming in this structure, that is: on the plane that is parallel to the tube sheet sealing surface, and tube sheet and bobbin carriage radial force and be heated inhomogeneous; This is unfavorable for the sealing of tube sheet and bobbin carriage, also directly has influence on service property (quality) and processing cost.
In view of flat pass partition heat exchanger exists above-mentioned deficiency, the utility model adopts the structural design with " Tubular Heat Exchanger of Circular Side Separation ".
The important difference of the utility model structural design is flat minute journey dividing plate with the bobbin carriage part, by the former plate cylinder type that changes into, in bobbin carriage configuration one or several with the coaxial circle of bobbin carriage housing every tube, to realize the structural requirement of two journeys or multipass formula heat exchanger.
Advantage of the present utility model is: 1. higher in annular branch journey medium temperature in tube (5), and when medium temperature is low outside tube, on the plane that is parallel to tube sheet (10) sealing surface, temperature gradient distribution radially is complete uniformity, temperature on the flange seal of tube sheet and bobbin carriage (7) face also is a uniformity, this not only helps cold and hot transition effects, and helps sealing; Because of every tube outer media temperature the end of than, former tube sheet and channel flange seal required usefulness " metal jacket gasket " or " SW with outside ring " and may change the asbestos rubber material into and make potted component, thereby reduce the cost of sealing element greatly, simplified processing technology; 3. owing to no longer include linearity branch journey groove on the tube sheet (10), and has only circular branch journey groove, make the tube sheet manufacture simplification easily go, only turning is processed a procedure and tube sheet cylindrical, sealing surface, branch journey groove all can be processed and easily guarantee machining accuracy.Reduced still need line and mill (or dig) two procedures of former processing, shortened the process-cycle and reduced process equipment; 4. seal for pipe joints face (comprising that flange and branch journey are every tube) all can adopt continuous turning processing, not only guarantees precision easily, and has improved working (machining) efficiency, avoided former sealing surface to add man-hour, can only cut by slow train because of there being dividing plate to stop, be interrupted processing, fast the inefficient processing technology of turning; 5. because gasket seal all is a ring-type, be easy to preparation and processing, no longer with the pad that must have muscle of cost height, processing time consuming; 6. owing to adopted annular minute journey, be easy to assembling and be easy to guarantee assembly precision than the flat pass partition of former usefulness every tube; 7. annular branch journey is applicable to fixed tube-sheet exchanger, movable tube sheets heat exchanger and U-shaped heat exchange of heat pipe too in tube both can be used on multipass formula heat exchanger structure more than two journeys; 8. different journeys of the present utility model can be selected the heat exchanger tube of centre-to-centre spacing between various heat exchange pipe (11) pipe and different tube diameters, different wall, unlike material, in the hope of reaching the required economy of different medium temperature, the requirement of conducting heat efficiently.
Description of drawings: Fig. 1 is intrinsic flat pass partition heat exchanger, and Fig. 2 is the Tubular Heat Exchanger of Circular Side Separation after improving.Wherein: 1 medium import (tube side); 2 media outlets (tube side); 3 media advance (or going out) mouthful (shell side); 4 media go out (or advancing) mouthful (shell side); 5 annulars divide journey every tube; Ring packing packing ring in 6; 7 outer shroud grommet type seal sheets (tube side side); 8 outer ring sealing gaskets allow (shell side side); 9 pipelines are sent out orchid; 10 tube sheets; 11 heat exchanger tubes; 12 flat minutes journey division boards; 13 bobbin carriage shells.
Embodiment:
According to the operating pressure of heat exchanger, operating temperature, medium characteristics, heat exchange area etc., according to " shell-and-tube heat exchanger design code " design, calculate.Determine diameter of the housing, heat exchanger tube quantity, material, diameter, wall thickness, and tube sheet material, thickness, branch journey groove diameter equidimension are drawn out manuscripts such as other part, portion's dress, general assembly.
According to manuscript, make the bobbin carriage end socket, the bobbin carriage housing.With the bobbin carriage end socket that processes, bobbin carriage housing, channel flange (9), annular branch journey isolating cylinder (5), medium import (1) and media outlet (2) assembly welding together.
In order to make the annular branch journey isolating cylinder can be coaxial, on the circumference three reinforcement plates be set evenly between annular branch journey isolating cylinder outer wall and bobbin carriage housing (13) inwall with channel flange (9).The bobbin carriage axis is crossed on the reinforcement plate plane, and weldering is connected with annular branch journey isolating cylinder with the bobbin carriage housing respectively at the reinforcement plate two ends.The postwelding heat treatment that eliminates stress is carried out in the footpath after the assay was approved again, and through operations such as turning, line, borings, bobbin carriage has just made again.
Tube sheet is pressed the figure blanking, divides the journey groove through turning processing tube sheet sealing surface and annular, processes pore through operations such as line, borings again.
For the fixed tube sheet tubular heat exchanger, when number of passes when two journeys are above, the two ends bobbin carriage all to be provided with one or several minutes the journey isolating cylinder.
All the other parts making and packaging technology and common heat exchanger processing technology are just the same.
Claims (3)
1, a kind of Tubular Heat Exchanger of Circular Side Separation of being made up of bobbin carriage, tube sheet, heat-exchanging tube bundle, shell side and housing is characterized in that the branch journey spacer assembly of bobbin carriage part is a cylindrical shape, also can be drum shape or taper shape; Branch journey groove on the tube sheet is circular; The different journeys of heat-exchanging tube bundle can be different tube pitch, different tube diameters, different wall, the heat exchanger tube of unlike material.
