Description

A kind of tube bank self-support heat exchanger
Technical field
The utility model relates to a kind of pipe heat exchanger, particularly relates 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 utility model provides a kind of novel tube bank self-support heat exchanger, fixed sleeving is utilized to realize support between support plate with heat exchanger tube and be connected, effective raising 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 utility model 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 beneficial effects of the utility model are:
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.
