Abstract
The utility model provides a steam-water separation device of a steam-water separation reheater. The steam-water separation device of the steam-water separation reheater is characterized by comprising a top part installation groove and a bottom part installation groove; at least one steam-water separation sheet is arranged between the top part installation groove and the bottom part installation groove; and the bottom part of the bottom part installation groove is provided with a water outlet; one sides of the steam-water separation sheets, which are close to the steam inlet, are provided with porous plates. The steam-water separation device of the steam-water separation reheater provided by the utility model can effectively separate two phases of steam and liquid, so that steam with a higher drying degree is obtained.
Description
Technical field
The utility model relates to a kind of separator water separator, belongs to nuclear power steam turbine generator technical group field.
Background technology
In nuclear power Turbo-generator Set separator, water separator is installed, can be carried out vapour to moist steam, liquid two is separated, thereby obtain the steam of needed higher mass dryness fraction.The Steam Turbine that PWR nuclear power plant uses is the saturated vapor unit.The saturated vapor that steam generator produces is sent to the steam turbine high-pressure cylinder work done, and the exhaust steam moisture of high pressure cylinder final stage is near 15%.As not taking any measure, after this kind steam is sent to low pressure (LP) cylinder, the low pressure (LP) cylinder exhaust steam moisture will will produce cavitation, water hammer to low pressure (LP) cylinder up to 20～24% left and right, will greatly shorten the service life of Steam Turbine.For avoiding occurring this situation, specialized designs the separator system.As shown in Fig. 1-2, structural representation for separator, comprise separator housing 1, be provided with successively secondary heating tube bundle 4, one-level heating tube bundle 3 and water separator 2 from a side to opposite side in separator housing 1, secondary heating tube bundle 4, one-level heating tube bundle 3 are connected with the two ends of separator housing 1 respectively; Water separator is arranged on both sides, housing below, is arranged symmetrically with centered by the housing axis.After the steam of high pressure cylinder is finished merit, be fed to separator, separate in separator with hot again, making the steam that enters low pressure (LP) cylinder is superheated steam, has lowered the erosion to the low pressure (LP) cylinder blade.Simultaneously, carbonated drink separator reheater system has also played reasonable distribution low pressure (LP) cylinder load, alleviates the function of high pressure cylinder load.Existing water separator separative efficiency is relatively low, resistance is relatively large, is not suitable for being applied to the exigent occasion of separative efficiency and resistance.
Summary of the invention
It is the problem that the water in moist steam is separated from moist steam that the utility model will solve, and guarantees extremely low pressure drop when effective lifting carbonated drink separative efficiency is provided.This device is arranged on separator inside, so it is must separative efficiency high, and compact conformation can satisfy the arrangement requirement of separator, and the steam drop by this device must be little simultaneously, can satisfy the performance requirement of separator.
In order to address the above problem, the utility model provides a kind of separator water separator, it is characterized in that, comprises top mounting groove and bottom mounting groove, be provided with at least one carbonated drink separate sheet between top mounting groove and bottom mounting groove, bottom mounting groove bottom is provided with delivery port; One side of carbonated drink separate sheet, be provided with porous plate near the moist steam porch.
Preferably, be provided with backing plate between every two adjacent described carbonated drink separate sheet.
Top mounting groove, bottom mounting groove are the parts of two channel steel shape structures, are used for fixedly carbonated drink separate sheet.The bottom has delivery port on mounting groove, has concurrently to collect the water separated and with the function of its discharge; The carbonated drink separate sheet is to carry out the main element of carbonated drink separation function in water separator, and it is arranged between top mounting groove and bottom mounting groove, and top mounting groove and bottom mounting groove are fixed the carbonated drink separate sheet from front and back, up and down four direction simultaneously; Porous plate is a plate shaped part part, is drilled with a large amount of apertures on it, before being arranged on the carbonated drink separate sheet, plays the effect of mean allocation flow.Moist steam enters the carbonated drink separate sheet flatly, equably from porous plate.In the carbonated drink separate sheet, water is separated from moist steam, under Action of Gravity Field, splashes in the mounting groove of bottom the delivery port discharger from the mounting groove of bottom; Dry saturated steam level passes through carbonated drink separate sheet bleeder.
The utility model can be effectively to moist steam carry out vapour, liquid two is separated, thereby obtain the higher steam of aridity.

The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
As shown in Figure 3, the separator water separator structural representation for the utility model provides comprises top mounting groove 5 and bottom mounting groove 7, is provided with an above carbonated drink separate sheet 6 between top mounting groove 5 and bottom mounting groove 7.Mounting groove 7 bottoms, bottom have delivery port 8.One side of carbonated drink separate sheet 6, be provided with porous plate 9 near the moist steam porch.Be provided with backing plate 10 between every two described carbonated drink separate sheet 6.Backing plate 10 is used for controlling the interval between adjacent carbonated drink separate sheet 6.
Moist steam enters water separator 2 from porous plate 9 levels, by the current balance function of porous plate 9, enters equably carbonated drink separate sheet 6 and carries out carbonated drink separation, as shown in the arrow on right side in Fig. 3.The water of separating splashes into downwards in the mounting groove 7 of bottom, and discharges from water separator 2 from delivery port 8, as shown in below arrow in Fig. 3; Dry saturated steam level flows out carbonated drink separate sheet 6, as shown in left side arrow in Fig. 3.
