Description
Technical field
The utility model belongs to nuclear power main equipment design field, and in particular to a kind of for evaporator water separator
Corrugated sheet.
Background technique
Key equipment one of of the steam generator as presurized water reactor nuclear power unit, effect is will be caused by reactor
Heat is passed to secondary coolant circuit system, and generates the steam for meeting performance indicator, is done work with pushing turbine.Carbonated drink in steam generator
It is mixed that separator (including steam-water separator, Gravity Separation space and drier) can remove the carbonated drink from U-shaped heating surface bank
The large quantity of moisture in object is closed, is the important component of natural circulation steam generator, work in every performance indicator is directly related to
The operational safety of steam generator and the work safety of steam turbine and working efficiency, or even the safety of entire nuclear power unit operation
Reliability, and the size of natural circulation steam generator depends greatly on the structure and work of water separator
Performance.Therefore guarantee water separator it is functional under conditions of, the compression height of water separator, body as far as possible
Product is the effective measures of the safety for guaranteeing nuclear power unit operation, reliability and miniaturization.
Currently, water separator carries out the crude separation of vapour-water mainly using rotation blade-type separator as the first order,
The drier being composed using corrugated sheet as the second level, carry out the subdivision of vapour-water from.In corrugated sheet drier, water droplet
By inertial impaction wooden partition and it is accumulated into moisture film, is then flowed downward out under the force of gravity.When drier inlet steam speed is super
Water droplet occurs when crossing critical speed, inside corrugated sheet to carry again, causes outlet humidity to steeply rise, substantial deviation use is wanted
It asks.In order to avoid reaching critical speed, generalling use higher corrugated sheet (more than 1m) increases inlet area, and steam is caused to be sent out
The size of raw device must also increase with it, to increase more manufacture processing, installation and transportation cost.Current corrugated sheet master
More mature and solidification is designed, but structure is complex using the band hook forms such as double hook or single hook, manufacture difficulty is big, and
In use there is the possibility to fall off in hydrophobic hook, will seriously affect drier performance, it is impossible to meet further decrease drier ruler
Very little, weight and reduction manufacture difficulty etc. require.
Summary of the invention
It is small in size, light-weight, easily fabricated the purpose of the utility model is to provide a kind of boxlike corrugated sheet drier,
And high reliablity.
The technical solution of the utility model is as follows:
A kind of boxlike corrugated sheet drier, the positioning strip including several corrugated sheets and between corrugated sheet, if described
Staggeredly head and the tail connect dry corrugated sheet up and down, retention gap between the upper corrugated sheet being located above, underlying lower corrugated sheet
Between retention gap, gap forms catch basin, and the positioning strip is mounted between upper and lower corrugated sheet.
The upper corrugated sheet and lower corrugated sheet are seen as sinusoidal wave shape from plate face side, and 90~130 ° of angle.
The point that the positioning strip is contacted with corrugated sheet is the trough or wave crest of corrugated sheet sine wave.
The corrugated sheet is equipped with several strip holes.
The arrangement mode in the strip hole is that uniformly arrangement, the sum of the height in each column strip hole account for corrugated sheet interleaving by columns
80% or more of total height.
A kind of boxlike corrugated sheet drier, including several corrugated sheets, staggeredly head and the tail connect several corrugated sheets up and down, are located at
Retention gap between the upper corrugated sheet of top, retention gap between underlying lower corrugated sheet, gap forms catch basin, described
Corrugated sheet be equipped with protrusion, raised top is in close contact with corresponding up/down corrugated sheet.
The upper corrugated sheet and lower corrugated sheet are seen as sinusoidal wave shape from plate face side, and 90~130 ° of angle.
The protrusion fixed point and corrugated sheet contact point are exactly the trough or wave crest of corrugated sheet sine wave.
The corrugated sheet is equipped with several strip holes.
The arrangement mode in the strip hole is that uniformly arrangement, the sum of the height in each column strip hole account for corrugated sheet interleaving by columns
80% or more of total height.
The beneficial effects of the utility model are as follows: current form plate usually forms sandwich formats by mainboard and hydrophobic hook,
Mainboard plays the role of fixing and supporting hydrophobic hook, and the utility model substitutes hydrophobic hook with the corrugated folded plate with strip hole, and head and the tail are right
It should be connected, weight be significantly reduced there is no need to mainboard by the intermediate each wave crest of the fixed support of positioning strip and trough, and increase
The sump volume that catchments.Lower corrugated sheet is moved to former mainboard position, so that waveform plate thickness is reduced, so that drier volume subtracts
It is small by 7% or more.When current form plate manufactures, needs for be accurately positioned the position of hydrophobic hook, then weld with mainboard, more take
When, and in there is the possibility to fall off in hydrophobic hook, will seriously affect drier performance, and this problem is then not present in the present invention,
And number of parts is reduced, small in size, light-weight, easily fabricated and high reliablity.
Detailed description of the invention
Fig. 1 is a kind of embodiment schematic diagram；
Fig. 2 is strip hole schematic diagram；
Fig. 3 is another embodiment schematic diagram；
In figure: corrugated sheet on 1.；2. lower corrugated sheet；3. positioning strip；4. catch basin；5. strip hole；6. protrusion.
Specific embodiment
Below by the drawings and the specific embodiments, the utility model is described in further detail.
Several corrugated sheets of a kind of embodiment staggeredly head and the tail connection up and down as shown in Figure 1, i.e., the rear end of upper corrugated sheet 1
Pass through retention gap between the upper corrugated sheet 1 that positioning strip 3 connect, and is located above with the front end of lower corrugated sheet 2, is located below
Lower corrugated sheet 2 between retention gap, gap formed catch basin 4.Later and so on.
Due to being mounted between upper and lower corrugated sheet for positioning strip 3, the height of positioning strip 3 is exactly upper corrugated sheet 1 and lower waveform
The distance of plate 2.The effect of positioning strip 3 is fixed corrugated sheet up and down, while upper and lower corrugated sheet composition is box-like.
Upper corrugated sheet 1 and lower corrugated sheet 2 are seen as sinusoidal wave shape, 90~130 ° of angle, preferably 120 ° from plate face side.Positioning
The point that item 3 is contacted with corrugated sheet is the trough or wave crest of corrugated sheet sine wave.The positioning strip 3 is with a thickness of waveform plate thickness
1~4 times, preferably 2 times；
As shown in Fig. 2, being machined with strip hole 5 in the plate face of corrugated sheet, permutation is arranged, and each 5 length direction of strip hole is
The sum of the height of the flow direction of water, each column strip hole 5 accounts for 80% or more of corrugated sheet total height.When the effect in strip hole 5 just
It is flowed into box in moisture film.
Preferably strip hole 5 it is each between interlaced arrangement, cannot be timely when preventing moisture film along wooden partition lateral flow
Into strip hole,
Another embodiment as shown in Figure 3.
The difference is that, without positioning strip 3, the protrusion 6 designed on corrugated sheet is substituted with upper one embodiment.It should
The top of protrusion 6 is in close contact with the plate face of corresponding upper corrugated sheet or lower corrugated sheet, and contact point is exactly corrugated sheet sine
The trough or wave crest of wave.Contact point is welded by the mode that welding can be used.In contrast be a little number of components reduce, just
In installation.But difficulty of processing is big.
