Abstract
The invention relates to a self-supporting type tube bundle heat exchanger. The self-supporting type tube bundle heat exchanger includes a tubular heat exchanger. Heat exchange tube bundles in the tubular heat exchanger are mutually supported through fixing sleeves installed outside single heat exchange tubes in a sleeving mode, and the heat exchange tube bundles are supported and fixed through supporting plates in the circumferential direction. The fixing sleeves press grooves to be closely connected with the heat exchange tubes. Compared with the prior art, the self-supporting type tube bundle heat exchanger has the advantages that media in a shell side form complex, continuous and uniform flow passages between the heat exchange tubes, the turbulence degree of the media is increased, a flowing boundary layer is thinned, heat transfer resistance is reduced, and therefore heat exchange efficiency is improved; the equipment is small in size, and the manufacturing cost is low; no baffle plate is arranged in the shell side, so that flowing dead zones in the shell side are eliminated, and the pressure drop of the media in the shell side is lowered; as no blind zone exists in the shell side, scaling is not prone to occur; the flow velocity is high in the shell side, so accumulation of impurities in the media is lowered; because large-area through holes are formed in a hole plate, compared with a traditional baffle plate, the heat exchange tubes are quite convenient to assemble and disassemble.
Description
Technical field
The present invention relates to a kind of pipe heat exchanger, particularly relate to a kind of tube bundle wrapper pore plate supporting type heat exchanger for the heat exchange of coking industry medium, problems such as can effectively solving impurity buildups sedimentation, heat exchange efficiency is low, shell side resistance is large.
Background technology
Tubular type (also known as shell-and-tube, shell and tube) heat exchanger is most typical dividing wall type heat exchanger, and its application industrially has long history, and still dominate in all heat exchangers so far.Pipe heat exchanger is primarily of housing, tube bank, tube sheet and envelope first class sections composition, and how rounded housing is, and bundle of parallel tubes is equipped with in inside, and tube bank two ends are fixed on tube sheet.
In pipe heat exchanger, carry out two kinds of fluids of heat exchange, a kind of at Bottomhole pressure, its stroke is called tube side; In the outer flowing of pipe, its stroke is called shell side, and the wall of tube bank is heat-transfer area.For improving extratubal fluid heat transfer coefficient, in housing, usually install the horizontal baffle plate of some, baffle plate not only can anti-fluid short circuit, increases fluid velocity, also force fluid by prescribed path repeatedly cross-flow by tube bank, less turbulence is greatly increased.Conventional plate washer has circle to lack shape and full circle shape two kinds.Fluid is often once called a tube side by tube bank in pipe, is often once called a shell side by housing.For improving the speed of tube fluid, dividing plate being set in the end socket of two ends whole pipe average mark is divided into some groups.Like this, fluid only can come and go tube bank repeatedly by partial tube at every turn, is called multitube distance.Equally, for improving the outer flow velocity of pipe, longitudinal plate washer can be installed in housing and make fluid Multiple through then out shell space, claiming muitishell.
Usually it is low to there is heat exchange efficiency in conventional tube shell heat exchanger, shell side medium impurity buildups, the shortcomings such as difficult cleaning, complex structure.Along with shell side supporting is tending towards simplifying, in recent years, occur that shell side does not need support and tube side self-supporting structure.At present, known tube bank has punching membrane chip, distorted elliptical tubular type, variable cross-section tubular type etc. from supporting form, but ubiquity makes the problem of processing difficulties, non-easy cleaning, detachable maintaining inconvenience.
Summary of the invention
The invention provides a kind of novel tube bank self-support heat exchanger, utilize fixed sleeving to realize support between support plate with heat exchanger tube and be connected, effectively improve heat exchange efficiency, reduce shell side and pile up impurity, have quick detachable, maintenance and cleaning in addition, equipment takes up an area little, the advantage such as cost is low.
In order to achieve the above object, the present invention realizes by the following technical solutions:
A kind of tube bank self-support heat exchanger, comprise pipe heat exchanger, the heat-exchanging tube bundle in described pipe heat exchanger is supported mutually by the fixed sleeving be sleeved on outside single heat exchange tube, and heat-exchanging tube bundle circumference is by support plate supporting and fixing.
Described fixed sleeving length is the heat exchanger tube node length of 1 ~ 1.5 times, and the groove that fixed sleeving compacting and heat exchanger tube shape adapt realizes the compact siro spinning technology between heat exchanger tube.
Described pipe heat exchanger is any one in floating head type pipe heat exchanger, U-shaped pipe heat exchanger or fixed tube-sheet exchanger, and its tube side is single tube journey or multitube distance.
Described support plate is full circle shape support plate, support plate is offered the through hole adapted with heat-exchanging tube bundle exterior contour, and according to single tube journey or multitube distance determination perforated area.
Described heat exchanger tube is any one in transversally flute tube, thread groove tube, helix tube, bellows, shaped telescopic tube or finned tube.
Compared with prior art, the invention has the beneficial effects as follows:
1) medium in shell side forms complicated continuous, uniform flow path between heat exchanger tube, improves its turbulent extent, is thinned the boundary layer of flowing, reduces heat transmission resistance, thus improve heat exchange efficiency;
2) due to the raising of heat exchange efficiency, heat exchange area can be made to reduce, and equipment volume declines thereupon, in addition this heat exchanger no baffle plate, and its manufacturing cost is reduced greatly;
3) due to no baffle plate in shell side, heat exchanger tube is supported mutually by fixed sleeving, and shell-side fluid is passed through from the gap between fixed sleeving, because this eliminating the flow dead in shell side, reduces the pressure drop of shell side medium:
4) due to non-blind area in shell side, therefore, this heat exchanger is less scaling; In addition, the special supporting construction of this heat exchanger can form higher flow velocity in shell side, thus also reduces the accumulation of impurity in medium:
5) orifice plate is offered large area through hole, compared to traditional deflection plate, heat exchanger tube is installed and is dismantled very convenient.
