Abstract
An improved efficient bypass floating head heat exchanger, comprising a shell, a left tube box, a left tube sheet, a floating head tube sheet, a floating head cover, a heat exchange tube, and a floating head end seal; wherein, the floating head end seal is arranged with an outlet; the outlet is connected through a delivery tube to a part of the shell, where the differential pressure to the inlet shall be higher than the flow resistance from the delivery tube to the port on the shell. The utility model has the following advantages: the utility model eliminates the medium retention area between the floating head end seal and the floating head cover, increases the service life, reduces the operation cost, and doesn't affect the medium flow rate and form in the shell.
Description
Technical field
The utility model belongs to a kind of shell-and-tube heat exchanger, particularly a kind of improved efficient floating head heat exchanger.
Background technology
Present shell and tube type floating head heat exchanger, its shell side outlet is arranged on the housing, and the shell side medium is discharged through the shell side outlet, form the stagnant area and enter the shell side medium of raising the nose above water to breathe to hold in the end socket, cause hot-spot easily, shorten its service life, improved operating cost simultaneously.For this reason, the applicant has developed a kind of " the efficient floating head heat exchanger of bypass ", number of patent application is 200620153434.6, promptly the cavity between floating head rear side and big end socket is provided with a by-pass conduit that is communicated in the shell side import, to activate the stagnant wake of floating head rear side in the shell side, but having certain deficiency is after a fluid streams enters into shell side, has influenced the main body flowing velocity and the form of shell side, and then has influenced its heat exchange efficiency.
The utility model content
The purpose of this utility model is in order to address the above problem, provide a kind of improved bypass efficient floating head heat exchanger, both eliminated the stagnant area of raising the nose above water to breathe shell side medium formation between end end socket and the floating head, improve its service life, reduce operating cost, do not influence the main body flowing velocity and the form of shell side simultaneously again.
The purpose of this utility model is achieved in that it comprises housing, left pipe box, left tube sheet, floating tubesheet, floating head, heat exchanger tube and floating head end end socket, it is characterized in that: raise the nose above water to breathe on the end end socket outlet to be set, this outlet is by a position on the delivery line connection housing, and the pressure reduction of this position and import department is greater than the flow resistance that enters into the shell side upper orifice from fairlead.The flow regime of shell side medium is under the situation that influences that is not subjected to this burst drainage medium basically like this, and the stagnant wake of shell side floating head back space is broken.Heat exchange efficiency steadily improves.
The utility model has the advantages that: both eliminated and raised the nose above water to breathe to improve its service life in the stagnant area that the shell side medium forms between end end socket and the floating head, reduced operating cost, do not influenced the main body flowing velocity and the form of shell side simultaneously again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
See Fig. 1, concrete structure is as follows: the utility model is the improvement of carrying out on the structure of floating head heat exchanger, original structure is provided with the housing 5 of band shell side import and export 4,14, and its left and right end connects the left pipe box 1 that tube side import and export 15,2 is set respectively and raises the nose above water to breathe end end socket 12.Assembling heat exchanger tube 6 between fixing left tube sheet 3 and the floating tubesheet 8, raising the nose above water to breathe end assembling end socket lid 13, improved technical essential is: raise the nose above water to breathe on the end end socket 12 outlet 10 to be set, this outlet 10 is by the import 7 at a position on the delivery line 9 connection housings, and the pressure reduction of this position and shell side import department should be greater than the flow resistance that enters into the shell side upper orifice from delivery line 9.
