Description
Technical field
The invention belongs to technical field of heat exchange more particularly to a kind of modular board-like condensers.
Background technology
Condenser is an important component of Steam Turbine, is an important ring for power plant's thermodynamic cycle, in order to meet
It is particularly significant to improve Performance of Condensers, optimization condenser size for the growth requirement of China's electric utility.It is applied from current power plant
From the point of view of present situation, shell-and-tube condenser since its is simple for process, it is applied widely the features such as and be widely used.But shell-and-tube condensing
There are certain defects for the structure and the type of flow of device, expose many problems in the process of running, and piping thermal prestressed is not easy to eliminate,
Fluid-pressure drop is big, the serious not easy-clear of fouling.
Relative to traditional shell-and-tube condenser, board-like condenser has heat transfer coefficient high, and pressure drop resistance is small, condenser end
The features such as difference is small, and condensate undercooling is low, the ripple of sheet surface can make fluid generate turbulent flow under smaller flow velocity, obtain higher
Surface convection transfer rate.Spacing bigger between plate so that the water resistance and vapour locking of condenser are all smaller, while are also less prone to tie
Dirt is easy to clean.The structure of plate so that board-like condenser is compact-sized, and space availability ratio is high.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of modular board-like condenser, which is characterized in that including plate
1 by being formed by welding the plate groups 3 with interlaced flow passage, and the both sides of plate are vapour side and water wing passage respectively, and convex bubble 2 is distributed
In vapour side, the water side of plate groups 3 is circulating water passage, and runner entrance is welded with plate connector 4, and plate connector 4 passes through bolt
It assembles to form condensing module 8 with first case A5 and boot A7, plate connector 4 is assembled and to be formed by bolt and head case B10 and boot B9
Incondensable gas refrigerating module 11；Condenser module 8 is inserted in the slot 15 of 14 lower section of entrance of condenser shell 13, boot A7
13 back back-trough 19 of condenser shell is inserted to, first case A5 is exposed to be connected outside with condenser shell 13, incondensable gas cooling
Module 11 is inserted in the slot 15 of 16 inlet of incondensable gas cooling chamber.
Respectively there are two identical discrepancy water pipes 6 for band by first case A5 and first case B10, and recirculated water is by one of water pipe stream that comes in and goes out
Enter, into first case A5 or first case B10, then flow into first order plate groups 3, boot A7 or boot B9 is then flowed into, by boot
A7 or boot B9 flow into next stage plate groups 3, then flow back to first case A5 or head case B10 and are flowed out from another discrepancy water pipe 6, are formed
Flow of the recirculated water in condensing module 8 and incondensable gas refrigerating module 11.
With protect-ing frame structure 12 in front of boot A7 and boot B9, it is enclosed in plate groups surrounding and protection and support is provided.
Steam is entered by entrance 14 inside condenser, from top to bottom the multiple plate groups 3 of approach, by the spacing for reducing plate
L so that the plate number for each plate groups 3 that steam from top to bottom passes through gradually increases.
Incondensable gas above two incondensable gas cooling chambers 16 of the lower section of condensing module 8 setting, condensed water, warp
After the incondensable gas refrigerating module 11 of 16 inlet of incondensable gas cooling chamber cools down, the pumping from 13 side of condenser shell
Mouth 17 is extracted out.
Condensation water collection is extracted out in 13 bottom of condenser shell from pump mouth 18.
The both sides of plate 1 are vapour side and water wing passage respectively, due to water side and vapour side there are pressure difference so 1 surface of plate point
There are many convex bubbles 2 for cloth to improve the bearing capacity of plate 1.Since vapour side is in negative pressure state under operating mode, so all convex bubbles 2
It is distributed in vapour side.Plate 1 is welded into plate groups 3, water side runner entrance welded plate strip terminal 4, by connector and condensing (no
Noncondensing gas cools down) module connects, and it is convenient to dismantle plate from module in maintenance, it is cleaned or is directly replaced.
Multiple spare condensing modules 8 and incondensable gas refrigerating module 11 are equipped with when board-like condenser is run, is being needed
When being cleared up or being overhauled, after old module only need to be extracted to simple cleaning enclosure interior, new module is directly changed
It puts into operation again, the module replaced can then be overhauled at rear, greatly reduced condenser and put into operation again
Time.Protect-ing frame structure effect on module boot is in the swapping process of operation and module to carry out plate groups necessary
Support and protection, avoid the deformation or breakage of the plate groups caused by plug.
It in the flow process of steam from top to bottom, constantly condenses, the volume of steam becomes smaller flow velocity reduction, causes pair
The stream coefficient of heat transfer constantly reduces.The thickness L of plate 1 has determined that 1 quantity of plate welded in a plate groups 3, passes through drop
The height of low convex bubble 2, reduces 1 thickness L of plate, increases by 1 number of plate, 3 heat exchange area of plate groups is increased, to strengthen steam flow channel
The heat transfer intensity of end improves overall heat exchange effect.
Advantageous effect：
Modular board-like condenser of the present invention, good effect of heat exchange is compact-sized small, is improving heat exchange efficiency
While, it is modular design substantially reduce from maintenance to the time put into operation again, and cause plate cleaning and
It replaces more convenient.
