Description
Technical field
The utility model is related to the technical field of heat exchanger, more particularly to a kind of ligulate baffle plate and pipe shell type heat exchange
Device.
Background technology
Shell-and-tube heat exchanger is also known as tubular heat exchanger or shell and tube condenser, and it is suitable for chemical industry, oil, doctors
" liquid --- liquid " in the industries such as medicine, food, light industry, metallurgy, coking, " vapour --- vapour ", the convection current of " vapour --- liquid " heat exchange
Heat transfer and the heat exchange condensation flow such as steam condensation and liquid evaporation, are the heat exchangers being most widely used.
Shell-and-tube heat exchanger is generally made of main members such as tube bank, housing, bobbin carriage, outer skulls, and tube bank is that shell and tube changes
The core of hot device is restrained usually by heat exchanger tube, baffle plate（Or referred to as support plate）It is formed with tube sheet, rows of heat exchanger tube passes through
Baffle plate supports that both ends are pierced into the pore of tube sheet to be connected with tube sheet, in the sealing for the connector for ensureing exchanger tubes and tubesheets
Property and intensity in the case of, you can as a tube bank, tube bank forms complete heat exchanger with housing, bobbin carriage again.Wherein, exchange heat
Pipe determines the heat transfer property of tubular heat exchanger, bobbin carriage and housing then determine shell and tube as heat conducting element together with baffle plate
The bearing capacity of heat exchanger and the security reliability of operation operation.The manufacturing process of this shell-and-tube heat exchanger is ripe, security
Can be high, it is crucial energy consumption equipment in heat transmission equipment.
In traditional technology, the structure of the commonly used baffle plate in tube bank is generally segmental baffle or is rolled in arch
The discount vibram outlet blocking solution shape baffle plate that is improved on the basis of flowing plate, ring disk and doughnut baffles, orificed plates, rod baffle etc., these
More or less all there are following shortcomings for baffle arrangement：(1) since flow direction is varied multiple times in shell-side fluid, easily exist
Baffle plate edge generates fluid separation, so as to increase flow resistance；(2) for segmental baffle, as shown in Figure 1, it circulates
Notch face 101 is plane, and 103 inner wall of housing is arrived in circulation notch face 101（Dotted line in Fig. 1）Full-size for H, H is arch
Baffle plate 100 for fluid by circulation notch 102 maximum height, due to the circulation notch 102 of segmental baffle 100
Intermediate altitude be significantly greater than height on both sides, and transition is not gentle enough so that the fluid for flowing through the circulation notch 102 is not equal enough
Weighing apparatus, and the flow velocity at 102 middle part of notch of circulating is slower, it is impossible to effectively wash away what is formed between segmental baffle 100 and housing 103
Turning causes the presence in much flowing stagnation dead zones, does not only result in heat transfer efficiency reduction so, and the fluid in stagnation dead zone holds
Easily in shell-side fouling, heat exchanger effectiveness decline is in turn resulted in；(3) for discount vibram outlet blocking solution shape baffle plate, due to fluid in discount vibram outlet area
In the tube axial direction flowing parallel to heat exchanger tube, heat transfer property is caused to decline；(4) for ring disk and doughnut baffles, shell-side fluid warp
The multiple baffling of baffle plate can generate distributary flowing, and then the mean temperature difference that will reduce heat transfer；(5) when the import and export pipe of shell side
During away from tube sheet farther out, flowing stop zone can become larger, and need to add guide shell, must increase the effective length of heat exchanger tube；(6) for
Deflection rod heat exchanger is hardly formed effective toll bar vortex in highly viscous medium, and then high heat transfer efficiency is not achieved
It is required that.
For traditional baffle plate there are the problem of, the countermeasure that people take is to cast off segmental baffle once and for all, using spiral shell
Rotation flat tube self supports heat exchanger tube or self supports heat exchanger tube using winding pipe or two-dimentional baffle plate is combined into helical baffles
Support heat exchanger tube etc., the baffle plate of these improved structures also brings use condition while above-mentioned subproblem is solved
The problem of limitation, the complexity of structure, new non-easy cleaning and repair, of high cost etc..In addition, with petrochemical plant
Large-scale development and power-saving technology index it is perfect, the nominal diameter that shell and tube exchanger is applicable in is expanded to from 2600mm
4000mm, the Enlargement Design of structure size can't natively bring the increased technological effect of linear scale, can amplify original instead
The shortcomings that having, for example, in the shell and tube exchanger of big nominal diameter, existing baffle arrangement（Including traditional baffle plate
With improved existing baffle plate）, a portion is not suitable for the shell and tube exchanger of big nominal diameter in itself, wherein separately
A part is so that itself existing above problem is more prominent and serious.Therefore, for above-mentioned problems and defect, research and development
The baffle plate and shell and tube exchanger that a kind of lamps structure is simple, designing technique is reliable, manufacturing process is ripe, infrastructure cost is low,
Effective heat exchange area and heat exchange efficiency can be improved, there is important engineering significance to steady production and economic benefit.

Or fixed tube-sheet exchanger, the heat exchanger that shell-side fluid is liquid or gas is applied also for, and especially suitable for big straight
The shell-and-tube heat exchanger in footpath, low flow velocity or both.The ligulate baffle plate of the present embodiment is applicable to changing for liquid or gas
Hot device.As shown in fig. 7, ligulate baffle plate is installed vertically in housing 1, shell-side fluid from the shell side inlet tube 11 of left upper part into
Enter, flowed along dotted line and arrow between ligulate baffle plate, finally left from the shell side inlet tube 11 of right end lower part, in baffling
Under the water conservancy diversion of auxiliary plate 3, fluid can fully be washed into 90 ° of corners such as A, B, C and D in Fig. 7, avoid the occurrence of poorly efficient or nothing
The flow dead zone of effect, in addition, when the shell side inlet tube 11 and shell-side outlet pipe 12 of the side of housing 1 all away from tube sheet farther out when, adopt
With above-mentioned ligulate baffle plate, in this way it is no longer necessary to add guide shell, you can guide the back of the body of fluid arrival tube sheet by the auxiliary body of baffling
Face, and then simplify heat exchanger structure.In addition, for traditional heat exchanger, tube bank therein is only needed to change（Tube bank includes heat exchange
Pipe, baffle plate and tube sheet）, you can reach the heat-transfer effect for enhancing heat exchanger, and then improve heat exchange efficiency, so that heat exchange
The technology upgrading of device is easy to operation, and cost input is few and energy-saving effect is notable.
