Abstract
The utility model provides a kind of PWR steam generator drier double hook corrugated sheet, and it can meet steam generator designing requirement.This double hook corrugated sheet comprises 1 piece of corrugated sheet, and this corrugated sheet is with several waveforms; Inner surface at each crest place of corrugated sheet is respectively connected 1 dash hook with on outer surface; Inner surface at each trough place of corrugated sheet is respectively connected 1 dash hook with on outer surface; 1 afterbody dash hook is also provided with at the tail end of corrugated sheet.Double hook corrugated sheet of the present utility model, its carbonated drink separative efficiency is high, and the steam of about 20% humidity enters after drier double hook corrugated sheet is separated further, obtains the dry saturated steam of humidity≤0.25%, meets the designing requirement of steam generator.Due to double hook corrugated sheet, it is larger and to catch water droplet more effective than other structure wetted areas existing, therefore separating effect is better.
Description
Technical field
The present invention relates to PWR steam generator drier design field, be specifically related to a kind of PWR steam generator drier double hook corrugated sheet technology.
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, make the water of secondary side become steam, steam, after initial separator and drier, leaves steam generator rear drive steam turbine and generates electricity.
Corrugated sheet is the core component of dryer for steam generator, and moist steam is under the effect of centrifugal force, inertia force and adhesive force, and the water droplet in steam is attached on corrugated sheet, and forms moisture film, and moisture film is more conducive to the attachment of fine liquid particles.The structural design of corrugated sheet is unreasonable, and drier separative efficiency can be caused to decline, and directly affects the generated output of nuclear power plant and the life-span of steam turbine.
For ensureing that steam turbine normally works for a long time, require that steam generator outlet steam moisture should be no more than 0.25% (percentage by weight).Current needs design a kind of waveform plate structure, and the steam of about 20% humidity enters after drier corrugated sheet is separated, and can obtain the steam of humidity≤0.25%.
Summary of the invention
The object of the present invention is to provide a kind of PWR steam generator drier double hook corrugated sheet, it can meet steam generator designing requirement: the steam of about 20% humidity enters after drier corrugated sheet is separated, and can obtain the steam of humidity≤0.25%.
The technical scheme realizing the object of the invention is as follows:
A kind of PWR steam generator drier double hook corrugated sheet, this double hook corrugated sheet comprises 1 piece of corrugated sheet, and this corrugated sheet is with several waveforms; Each crest of corrugated sheet and the inner surface at trough place are respectively connected 1 dash hook; 1 afterbody dash hook is also provided with at the tail end of corrugated sheet.
Above-mentioned corrugated sheet is with 6 crests and 6 troughs.
Above-mentioned dash hook is connected with adopting the form of electric resistance welding between corrugated sheet.
Above-mentioned afterbody dash hook and corrugated sheet are integrated machine-shaping, and namely the tail end of corrugated sheet is bent to form hook formation.
Beneficial effect of the present invention is:
The invention provides a kind of PWR steam generator drier double hook corrugated sheet, its carbonated drink separative efficiency is high, the steam of about 20% humidity enters after drier double hook corrugated sheet is separated further, obtains the dry saturated steam of humidity≤0.25%, meets the designing requirement of steam generator.
When vapor stream is through corrugated sheet region, the water droplet in steam is attached on corrugated sheet, and the dash hook on corrugated sheet and afterbody dash hook place collect, and the water of formation flows into steam trap connection downwards along hook-type.Dash hook and afterbody dash hook realize the water collected on wooden partition and the water droplet function of catching in vapor stream.The qualified steam collected flows out from double hook corrugated sheet assembly, leaves steam generator, for steam turbine power generation.Due to double hook corrugated sheet, it is larger and to catch water droplet more effective than other structure wetted areas existing, therefore separating effect is better.
Accompanying drawing explanation
Fig. 1 is a kind of PWR steam generator drier double hook corrugated sheet structural representation of the present invention.
In figure: 1 is corrugated sheet; 2 is dash hook; 3 is afterbody dash hook.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a kind of PWR steam generator drier double hook corrugated sheet of the present invention is further described.
As shown in Figure 1, a kind of PWR steam generator drier double hook corrugated sheet of the present invention, it mainly comprises 1 piece of corrugated sheet 1 and several dash hooks 2.
This corrugated sheet 1 is with 6 waveforms, and namely corrugated sheet 1 is with 6 crests and 6 troughs.
On each crest of corrugated sheet 1 and the surfaces externally and internally at trough place, each form of electric resistance welding that adopts is connected 1 dash hook 2.
1 afterbody dash hook 3 is also provided with at the tail end of corrugated sheet 1.This afterbody dash hook 3 is integrated machine-shaping with corrugated sheet 1, and namely the tail end of corrugated sheet 1 is bent to form hook formation.
The corrugated sheet 1 of double hook corrugated sheet of the present invention can with several waveforms, such as 8 or 10.
In the present invention, PWR steam generator drier is just made up of above-mentioned some pieces of double hook corrugated sheets.The moist steam that steam generator produces is first by the separation of initial separator, make the steam moisture of steam water interface about 20%, the steam of about 20% humidity enters after drier is separated further, obtains the dry saturated steam of humidity≤0.25%, meets the designing requirement of steam generator.
When a kind of PWR steam generator drier double hook corrugated sheet of the present invention uses:
Vapor stream is through corrugated sheet region, and the water droplet in steam is attached on corrugated sheet, and the dash hook 2 on corrugated sheet and afterbody dash hook 3 place collect, and the water of formation flows into steam trap connection downwards along hook-type.Dash hook 2 and afterbody dash hook 3 realize the water collected on wooden partition and the water droplet function of catching in vapor stream.The qualified steam collected flows out from double hook corrugated sheet assembly, leaves steam generator, for steam turbine power generation.The design of double hook corrugated sheet can meet the designing requirement of nuclear power station steam generator drier.
Above embodiments of the invention are explained in detail, above-mentioned embodiment is only optimum embodiment of the present invention, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
