Description
Technical field
The invention belongs to nuclear power main equipment design fields, and in particular to a kind of evaporator water separator drier.
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 waveform is hardened
Structure design is more mature and solidification, the separative efficiency and critical speed of water droplet are difficult to further increase, and it is impossible to meet further
Compressed waveform board size and the requirement for reducing outlet humidity.
Summary of the invention
The object of the present invention is to provide a kind of chevron with hooks drier, critical speed is big, separative efficiency is high.
Technical scheme is as follows:
A kind of chevron with hooks comprising baffle upper plate and chin spoiler, the pintle positioned at right end and position positioned at left end
Several hydrophobic hooks in middle part, several described hydrophobic hooks are staggeredly formed by connecting from beginning to end up and down, and junction is opened equipped with band
The catch basin of mouth；The baffle upper plate and chin spoiler is fitted closely in outer end, and the end of chin spoiler extends back,
The pintle front end is bending section, rear end straight panel, the hydrophobic hook welded closed of straight panel and front.
The hydrophobic hook includes the bending part of end, the protrusion at middle part and for arc tail portion.
The arc tail portion radian of the hydrophobic hook is 90~130 °.
The bending part of the hydrophobic hook forms catch basin, and the raised arc tail portion with previous hydrophobic hook is in close contact,
The arc tail portion of the hydrophobic hook extends back, and is in close contact with the protrusion of the hydrophobic hook of the latter.
The opening of the catch basin increases with water (flow) direction.
A kind of chevron with hooks drier, it is made of two identical chevron with hooks, and steam and water droplet are from two bands
It is flowed through in runner between hook corrugated sheet.
The chevron with hooks includes the baffle upper plate and chin spoiler positioned at left end, the pintle positioned at right end and is located at
Several hydrophobic hooks at middle part, several described hydrophobic hooks are staggeredly formed by connecting from beginning to end up and down, and junction is equipped with band opening
Catch basin；The baffle upper plate and chin spoiler is fitted closely in outer end, and the end of chin spoiler extends back, institute
The pintle front end stated is bending section, rear end straight panel, the hydrophobic hook welded closed of straight panel and front.
The hydrophobic hook includes the bending part of end, the protrusion at middle part and for arc tail portion.
The arc tail portion radian of the hydrophobic hook is 90~130 °.
The opening of the catch basin increases with water (flow) direction.
The tail portion of the hydrophobic hook is shortened with water (flow) direction, so that the opening of catch basin increases with water (flow) direction.
Remarkable result of the invention is as follows:
Since hydrophobic hitcher has arc tail portion and bending part, and up and down, head and the tail are connected, so that the section of chevron with hooks
It is also in sinusoidal wave shape in sine wave, therefore by the two panels chevron with hooks steam and water droplet channel arranged in parallel of being formed by；
Simultaneously because the opening of catch basin by small gradually big, be made of hydrophobic hook arc tail portion, deflector, bending part, open
Begin to be formed and easily goes out structure into hardly possible, with water (flow) direction, the opening of catch basin is in U-shape, the slot number of catchmenting in runner is increased greatly,
Enable the nearest alienation of moisture film, it is therefore prevented that the generation carried again.
