Description

A kind of shell-and-tube heat exchanger
Technical field
The utility model relates to a kind of shell-and-tube heat exchanger, can realize of heat transfer and don't the generation quality transmission of a kind of fluid to another fluid, relate in particular to the process equipment that needs to strengthen the shell side heat exchange in a kind of large-scale double segmental baffle shell-and-tube heat exchanger, belong to the augmentation of heat transfer technical field.
Background technology
At present, known shell-and-tube heat exchanger is by container casing, shell-side fluid import, shell-side fluid outlet, deflection plate, heat exchanger tube, tube sheet, end socket, the tube side fluid import, and tube side fluid outlets etc. are formed.When high temperature fluid when the shell side import enters, cryogen just enters from the tube side import; When high temperature fluid when the tube side import enters, cryogen just enters from the shell side import; Fluid at differing temperatures is carried out the heat transmission by heat exchanger tube then.Because the circulation area between the shell-and-tube heat exchanger shell side is very big, cause between shell flowing velocity very little, cause the surface film thermal conductance of heat exchanger tube shell side side very little.
In general, flowing of shell side side can be divided into several principal modes such as jet that deflection plate forms to the axial cross-flow passes of vertical tube between the axial flow that is parallel to the heat exchanger tube axis between time deflection plate, deflection plate and because of the annular space between pipe and deflection plate is mobile; From the angle of amount, for the wriggling burn into jet wearing and tearing that solve heat exchanger tube and the supporting role of strengthening deflection plate become interference fit with deflection plate with heat exchange tube design, thereby the jet between shell side is mobile can ignore; And along with shell-and-tube heat exchanger to the development of maximizing, radial dimension also just becomes big gradually with respect to the yardstick of baffle(s) spacing, thereby makes cross-flow passes become main liquid form between the large tubular heat exchanger shell pass.
But the cross-flow passes between shell side can form very big stagnant area at the rear portion of heat exchanger tube, when the heat exchanger tube employing is cleaned arranged in squares easily, the area that heat exchanger tube shell side side is in the stagnant area surpasses more than 1/3rd, the heat exchange area that is to say this part heat exchanger tube is not made the contribution of oneself to heat transfer, thereby has reduced the heat exchange effect of shell-and-tube heat exchanger.On the other hand, in the position of deflection plate, also can make this regional heat exchanger tube lose its heat transmission function because of the stagnant area that direction changes and formation is very big of its baffling to shell-side fluid away from its opening.
Summary of the invention
The purpose of this utility model provides a kind of stagnant area that not only can effectively suppress the heat exchanger tube behind in the cross-flow zone, and can effectively reduce the shell-and-tube heat exchanger away from deflection plate aperture position stagnant area.
For realizing above purpose, the technical solution of the utility model provides a kind of high-performance heat exchanger, comprise the tube side fluid import, end socket, tube sheet, the tube side fluid outlet, the shell-side fluid outlet, the U-shaped heat exchanger tube, housing, the shell-side fluid import, the two ends above the housing are located in tube side fluid import and shell-side fluid import respectively, the lower end of housing is located in tube side fluid outlet and shell-side fluid outlet respectively, end socket is located at an end of housing, it is characterized in that, the U-shaped heat exchanger tube passes at least one limit deflection plate and is located in the middle of the housing by tube sheet, the place vertically is provided with at least one damper tube at edge break stream board diameter, the place is provided with at least one damping baffle plate parallel with the limit deflection plate in housing upper and lower side space, the damping baffle plate is connected with the limit deflection plate by the U-shaped heat exchanger tube, is provided with pull bar in the housing both sides.
For improving the coefficient of heat transfer of heat exchanger tube at the shell side face, the utility model employing deflection plate reduces the circulation area between shell side, increases the flowing velocity of fluid between shell side, and then has strengthened the diabatic process of heat exchanger tube at the shell side side surface.
The utility model utilizes the space of not arranging heat exchanger tube between damping sheet to promote the shell side inner fluid at the static energy away from the deflection plate aperture position, thereby increase motive force along the fluid on the deflection plate plane, and then elimination is away from the stagnant area of deflection plate opening part heat exchanger tube shell side side, the diabatic process of enhanced tube shell heat exchanger; Because the pressure impetus between damping sheet is interfered the cross-flow passes of pipe way, eliminate the stagnant area that fluid flows and forms effectively between heat exchanger tube simultaneously, also strengthened diabatic process well; Sealed tube also plays this effect.Damping sheet, damper tube are connected with deflection plate, have increased the rigidity of deflection plate, can effectively reduce the high temperature wriggling corrosion of heat exchanger tube.Pull bar and barrel are realized minimum clearance, can reduce fluid effectively along the short-circuit flow that the cylindrical shell wall forms, and also can play the effect of augmentation of heat transfer.
The utility model has the advantages that the stagnant area of reducing shell-side fluid heat exchanger tube rear portion, improve the exchange capability of heat of heat exchanger tube in the cross-flow stagnant area; Reduce stagnant area simultaneously, improve heat exchanger tube at exchange capability of heat away from the deflection plate aperture position away from the deflection plate aperture position.
