Description

One kind tube bank self-support heat exchanger
Technical field
The present invention relates to a kind of pipe heat exchanger, more particularly to a kind of tube bank sleeve pipe for media for heat exchange in coking industry Orifice plate supporting type heat exchanger, can effectively solve the problem that impurity accumulation sedimentation, the problems such as heat exchange efficiency is low, shell side resistance is big.
Background technology
Tubular type (also known as shell-and-tube, shell and tube) heat exchanger is most typical dividing wall type heat exchanger, its application industrially There is long history, and still occupy leading position in all heat exchangers so far.Pipe heat exchanger is main by housing, pipe How rounded beam, tube sheet and envelope first class sections composition, housing is, and inside is equipped with bundle of parallel tubes, and tube bank two ends are fixed on tube sheet.
The two kinds of fluids exchanged heat in pipe heat exchanger, one kind is in Bottomhole pressure, and its stroke is referred to as tube side;One kind exists Pipe is outer to be flowed, and its stroke is referred to as shell side, and the wall of tube bank is heat-transfer area.To improve extratubal fluid heat transfer coefficient, generally in shell A number of horizontal baffle plate is installed in vivo, baffle plate can not only prevent fluid short, increase fluid velocity, also force Fluid, by tube bank, greatly increases less turbulence by the regulation multiple cross-flow in path.Conventional plate washer has discount vibram outlet shape and full-circle spray pattern Two kinds.Fluid is often once referred to as a tube side in pipe by tube bank, is often once referred to as a shell side by housing.To improve pipe The speed of interior fluid, sets dividing plate by whole pipe equipartitions into some groups in the end socket of two ends.So, fluid can every time only Tube bank is come and gone by partial tube multiple, referred to as multitube distance.Equally, to improve the outer flow velocity of pipe, longitudinal direction can be installed in housing Plate washer makes fluid multipass shell space, claims muitishell.
It is low generally to there is heat exchange efficiency in traditional shell-and-tube heat exchanger, the accumulation of shell side medium impurity, hardly possible cleaning, complicated etc. Shortcoming.As shell side supporting tends to simplify, in recent years, occur in that shell side does not need support i.e. tube side self-supporting structure.Mesh Before, it is known that tube bank self-supporting form have punching membrane chip, distorted elliptical tubular type, variable cross-section tubular type etc., but generally existing makes The problem of processing difficulties, non-easy cleaning, detachable maintaining are inconvenient.
The content of the invention
The invention provides a kind of new tube bank self-support heat exchanger, support plate and heat exchange are realized using fixed sleeving Support and connection between pipe, effectively improve heat exchange efficiency, reduce shell side accumulation impurity, additionally with quick detachable, maintenance and Cleaning, the advantages of equipment takes up an area small, low cost.
In order to achieve the above object, the present invention is realized using following technical scheme:
Heat-exchanging tube bundle in one kind tube bank self-support heat exchanger, including pipe heat exchanger, the pipe heat exchanger passes through The fixed sleeving being sleeved on outside single heat exchange tube is supported mutually, and heat-exchanging tube bundle circumferentially passes through support plate supporting and fixing.
The fixed sleeving length is 1~1.5 times of heat exchanger tube node length, fixed sleeving compacting and heat exchange tube shape phase The groove of adaptation realizes the close connection between heat exchanger tube.
The pipe heat exchanger is in floating head type pipe heat exchanger, U-shaped pipe heat exchanger or fixed tube-sheet exchanger Any, its tube side is single tube journey or multitube distance.
The support plate is that the through hole being adapted with heat-exchanging tube bundle exterior contour is opened up on full-circle spray pattern support plate, support plate, And perforated area is determined according to single tube journey or multitube distance.
The heat exchanger tube is any of transversally flute tube, thread groove tube, helix tube, bellows, shaped telescopic tube or finned tube.
Compared with prior art, the beneficial effects of the invention are as follows:
1) medium in shell side forms continuous, the uniform flow path of complexity between heat exchanger tube, improves its turbulent extent, subtracts The boundary layer of thin flowing, reduces heat transmission resistance, so as to improve heat exchange efficiency;
2) due to the raising of heat exchange efficiency, heat exchange area can be reduced, equipment volume declines therewith, in addition the heat exchanger without Deflection plate so that its manufacturing cost is substantially reduced;
3) due to no baffle plate in shell side, heat exchanger tube is mutually supported by fixed sleeving, shell-side fluid from fixed sleeving it Between gap pass through, it is thus eliminated that the flow dead in shell side, reduces the pressure drop of shell side medium:
4) due to non-blind area in shell side, therefore, the heat exchanger is less scaling;In addition, the special supporting construction of this heat exchanger Higher flow velocity can be formed in shell side, so as to also reduce the accumulation of impurity in medium:
5) large area through hole is opened up on orifice plate, compared to traditional deflection plate, heat exchanger tube is installed and dismantled very convenient.
