Abstract
The invention relates to a single-hook corrugated plate for a dryer of a pressurized water reactor steam generator. The single-hook corrugated plate comprises a corrugated plate body, the outer surface of each crest and the outer surface of each trough are each provided with a water retaining hook, and openings formed by the water retaining hooks and the corrugated plate body face the same direction. Compared with the structure of a four-hook corrugated plate which is usually adopted in the prior art, the single-hook corrugated plate has the advantages of being larger in wetting area, more effective in water drop capturing, relatively lower in separating resistance, high in steam-water separating efficiency and capable of meeting the design requirement of the steam generator.
Description
Technical field
The present invention relates to the steam generator of presurized water reactor in nuclear power station, particularly relate to a kind of drier corrugated plates separator of PWR steam generator.
Background technology
Steam generator is the heat transmission equipment between PWR nuclear power plant one, secondary circuit, for the heat of reactor coolant is passed to secondary side, makes the water of secondary side become moist steam.Moist steam, after initial separator, Gravity Separation district, drier, produces the dry saturated steam met design requirement, and dry saturated steam is used for driving steam turbine and generates electricity.
Drier is last one separator of steam generator.Moist steam is through drier core component--carry out curvilinear motion during corrugated sheet, under the effect of centrifugal force, inertia force and adhesive force, the water droplet in steam is attached on corrugated sheet, and forms moisture film.
The unreasonable carbonated drink separative efficiency that will cause of drier core parts corrugated sheet structural design declines, and directly affects the outlet vapor humidity of steam generator, and then affects the generated output of nuclear power plant and the life-span of steam turbine.And corrugated sheet of the prior art design also also exists defect, such as: 1, the wave band of corrugated sheet is very few, cause wetted area that corrugated sheet produces too small, the effect catching water droplet declines; 2, moist steam does not meet obstructions in the process of advancing, and therefore most moist steam is directly by corrugated sheet, does not reach dry effect.
Summary of the invention
The present invention is exactly to solve the problem, and overcomes the problem in prior art existing for corrugated sheet, the invention provides a kind of drier corrugated plates separator of PWR steam generator to satisfy the demands.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of drier corrugated plates separator of PWR steam generator, comprise corrugated sheet, it is characterized in that, each crest of described corrugated sheet and the outer surface of trough are provided with a dash hook, and the opening formed between described dash hook and corrugated sheet is towards same direction.
The drier corrugated plates separator of above-mentioned a kind of PWR steam generator, is characterized in that, described corrugated sheet is provided with more than six wave bands.
The drier corrugated plates separator of above-mentioned a kind of PWR steam generator, is characterized in that, the described shape of dash hook is identical with the shape of trough with the crest of corrugated sheet, on the crest that one end of described dash hook is connected to corrugated sheet and trough.
The drier corrugated plates separator of above-mentioned a kind of PWR steam generator, is characterized in that, described dash hook is connected by electric resistance welding with between corrugated sheet.
The drier corrugated plates separator of above-mentioned a kind of PWR steam generator, it is characterized in that, on described corrugated sheet, moist steam enters the side of corrugated sheet is head, on corrugated sheet, moist steam outlet side is afterbody, the afterbody of described corrugated sheet is provided with bending stop hook, and the opening direction of described bending stop hook is consistent with the opening direction of dash hook.
The invention has the beneficial effects as follows: compared with the 4 hook corrugated sheet structures adopted usual in prior art, wetted area is larger, seizure water droplet is more effective, and have relatively low separation resistance, carbonated drink separative efficiency is high, can meet steam generator designing requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Referring to Fig. 1, a kind of drier corrugated plates separator of PWR steam generator, comprise corrugated sheet 100, each crest of corrugated sheet 100 and the outer surface of trough are provided with a dash hook 200, and the opening formed between dash hook 200 and corrugated sheet 100 is towards same direction.Steam is when by corrugated sheet 100, and the water droplet first in steam is attached on corrugated sheet 100 and forms moisture film, and moisture film is more conducive to the attachment of fine liquid particles.Then vapor stream is through the dash hook 200 of corrugated sheet 100, the water droplet that dash hook 200 can be collected the water on wooden partition and catch in vapor stream, and the water collected flows into steam trap connection downwards along dash hook 200.
Corrugated sheet 100 is provided with more than six wave bands, namely comprises six crests and six troughs, and it is compared with the four hook corrugated sheet structures adopted, and wetted area is larger and catch water droplet more effectively, have relatively low separation resistance, therefore separating effect is better.
The shape of dash hook 200 is identical with the shape of trough with the crest of corrugated sheet 100, and on the crest that one end of dash hook 200 is connected to corrugated sheet 100 and trough, dash hook 200 is connected by electric resistance welding with between corrugated sheet 100 simultaneously.
On corrugated sheet 100, moist steam enters the side of corrugated sheet 100 is head 110, on corrugated sheet 100, moist steam outlet side is afterbody 120, the afterbody of corrugated sheet 100 is provided with bending stop hook 130, the opening direction of bending stop hook 130 is consistent with the opening direction of dash hook 200.
The invention has the beneficial effects as follows: compared with the 4 hook corrugated sheet structures adopted usual in prior art, wetted area is larger, seizure water droplet is more effective, and have relatively low separation resistance, carbonated drink separative efficiency is high, can meet steam generator designing requirement.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
