Abstract
The utility model discloses a double-shell-side twisted oblate tube heat exchanger, which comprises a shell, a fixing tube plate, U-shaped heat exchange tubes and a partition; wherein, the U-shaped heat exchange tubes assembled in the shell are fixed on the fixing tube plate; the heat exchange tube bundles are partitioned by the partition; an oblate tube with an elliptic section is adopted as the U-shaped heat exchange tube; the heat exchange tube bundles are arranged in the shape of a honeycomb; each U-shaped heat exchange tube is twisted along the extending direction of the axial line; moreover, each U-shaped heat exchange tubes is twisted at the same angle; the adjacent U-shaped heat exchange tubes are contacted with one another by points along spiral lines; and on any section in the direction of the axial line of the heat exchange tube bundle, the U-shaped heat exchange tubes are connected together along the direction of the long axis of the ellipse to form multiple parallel straight lines. The structure of the heat exchanger ensures that both tube side fluid and shell side fluid can flow mainly in a complex whirling manner, thus intensifying the heat-transferring process. Without baffles and dead flow areas, the heat exchanger cannot easily scale. The double-shell-side structure enlarges the heat-exchanging area and reduces the space occupied by the device.
Description
One, technical field
The utility model belongs to heat exchanger manufacturing technology field, is specifically related to a kind of heat exchanger as petrochemical equipment.
Two, background technology
The structure of heat exchanger and its heat exchange efficiency and cost have confidential relation, and the influence of the shape heat exchanging device efficient of heat exchanger tube is even more important.The heat exchanger tube that has used at present divides from cross sectional shape pipe and flat tube, has seen light pipe and screwed pipe etc. from extending in form, and the heat exchanger tube that these structures are different all has its advantage separately.But awaiting further to improve on the heat exchange efficiency and in the utilization of material.
Three, summary of the invention
The purpose of this utility model provides a kind of double shell pass spiral distortion flat pipe heat exchanger, the cross sectional shape by changing heat exchanger tube and extend the heat exchange efficiency that shape improves heat exchanger.
Double shell pass spiral distortion flat pipe heat exchanger comprises housing, fixed tube sheet, U-shaped heat exchanger tube and dividing plate, and the U-shaped heat exchanger tube that is contained in the housing is fixed on the fixed tube sheet, is separated by dividing plate in the middle of the heat-exchanging tube bundle, makes the shell side medium become double-current journey by single process.The U-shaped heat exchanger tube adopts the flat tube with oval cross section, and heat-exchanging tube bundle is honeycomb and arranges; The U-shaped heat exchanger tube becomes helically twisted shape along the axis bearing of trend, and the distortion angle of each U-shaped heat exchanger tube is identical, along the contact of helix point, on the arbitrary cross section of heat-exchanging tube bundle axis direction, each U-shaped heat exchanger tube all connects into many parallel lines along the transverse direction between the adjacent U-shaped heat exchanger tube.In heat exchanger shell, do not establish deflection plate, adopt a plurality of bundle hoops that tube bank is tied together.
Each heat exchanger tube of the utility model all becomes helically twisted shape, and whole heat-exchanging tube bundle forms a big spiral.The complexity that the structure of double shell pass spiral distortion flat pipe heat exchanger all produces to rotate to be principal character tube side fluid and shell-side fluid flows, and obtains stronger rotation and stirs, thereby strengthened diabatic process largely.Because there is not deflection plate, there is not flow dead in shell side, and the flow resistance of shell side is very little, and is simultaneously less scaling yet.Mainly do vertically to flow through adjacent helix holding point contact and shell-side fluid between the heat exchanger tube, not only increased the quantity of heat exchanger tube but also can well overcome induced vibration, improved the reliability of its operation.Thereby adopt bivalve journey structure to make the flow process of shell-side fluid increase heat exchange area in addition, reduced equipment and taken up space.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3, Fig. 4, Fig. 5 are the partial sectional view of the utility model heat-exchanging tube bundle along the axis direction different cross section.
Five, the specific embodiment
Double shell pass spiral distortion flat pipe heat exchanger is based on the conventional tube shell heat exchanger, change the pipe in the shell-and-tube heat exchanger into helically twisted flat tube as heat exchange element, do not establish deflection plate in the tube bank, the heat exchanger tube outer rim keeps helix closely to contact, play mutual supporting role and form the screw type runner between heat exchanger tube, other structure all adopts the part of shell-and-tube heat exchanger.Helically twisted flat tube is to flatten the back distortion by pipe to form, the cross section is oval, can suppress the heat exchanger tube of different flattening degree and different pitch according to actual needs, for the ease of being connected of U-shaped heat exchanger tube 3 and fixed tube sheet 1, the two ends of helically twisted flat tube are circular.In the centre of heat-exchanging tube bundle, the tube bank with dividing plate 4 separation both sides makes the shell side medium become double-current journey by single process.During double shell pass spiral distortion flat pipe heat exchanger tube bank assembling, fixed tube sheet 1 is fixed in the end of U-shaped heat exchanger tube 3, and the other end is the U type.The helically twisted flat tube of every installation one row, turne tube are guaranteed that the pipe outward flange on each plane joins and are touched.For the rigidity needs of restraining, in tube bank, be furnished with several roads and prick hoop 2, guarantee that interbank maintenance closely contacts and the extraction and the lifting of convenient tube bank.
