Technical field
Application field is studied the present invention relates to corrugated sheet drier, more particularly to it is a kind of each for studying corrugated sheet drier
The hydrophobic slot structure of level separating capacity.
Background technology
During steam generator is PWR nuclear power plant, by the heat transfer of the reactor coolant of primary Ioops to secondary circuit
Nucleus equipment, i.e., be heated into steam using primary Ioops by the water in secondary survey, after the steam is by water separator, into vapour
Turbine, and drive steam turbine acting generating.
Corrugated sheet drier has been widely used in the steam-water separation field in PWR nuclear power plant, is dried in corrugated sheet
In device design application process, it is impossible to predict corrugated sheet drier separating capacity at different levels, the selection of corrugated sheet series is not in the presence of true
It is qualitative.
Existing experimental study shows that corrugated sheet drier series is improved, and separating capacity first rises remains stable afterwards, drier
Drag losses be then it is continuous rise, these have all influenceed on the reliability and economy of drier, therefore in experimental study
In need to design a kind of hydrophobic slot structure, in the case where not influenceing drier interior flow field be used for study each series of drier point
From ability, the selection of series provides reference in being designed for drier.
The content of the invention
The purpose of the present invention be for corrugated sheet drier operationally separating capacities at different levels are unknown and providing one kind is used for
The hydrophobic slot structure of corrugated sheet drier separating capacities at different levels is studied, is that one kind is applicable to grind in Cold simulating test and Thermal-state test
Study carefully the separation energy of each series of corrugated sheet under different air velocities, mixture humidity, mean droplet size, corrugated sheet structural condition
The hydrophobic slot structure of power.
The object of the present invention is achieved like this：Including drain tank platform, water trough body, tank dividing plate, hydrophobic conduit, dredge
Sink deck is located at below the corrugated sheet of corrugated sheet drier, is provided with a rectangle hole slot on drain tank platform, water trough body is
One rectangular groove structure and water trough body is embedded in rectangle hole slot, tank dividing plate is uniformly arranged in water trough body and by water trough body
Independent compartment is separated into, the number of compartment is equal with the flanging number of corrugated sheet, and water trough body is provided with corresponding with compartment number
Weep hole, the quantity of hydrophobic conduit is equal with the quantity of weep hole and hydrophobic conduit is connected with weep hole, the end of drain pipe
It is connected with collection device.
Present invention additionally comprises some such architectural features：
1. water trough body upper surface is flushed with hydrophobic sink deck upper surface.
Compared with prior art, the beneficial effects of the invention are as follows：The cold conditions and hot reality of corrugated sheet drier can be used in
In testing, and solve two problems：One, can prevent drier interior air-flow from being flowed in drain tank, the compartment number of the structure setting with
The flanging number of corrugated sheet is equal, and the dividing plate of compartment is connected with corrugated sheet bottom, has prevented drier interior air-flow in drain tank
Flowing, is not interfered with to drier interior flow field.Two, moisture content of the corrugated sheet drier per the separation of one-level wall can be independently collected,
Drier separating capacity at different levels is studied, effective series of drier is determined, it is to avoid made during drier type selecting because series is very few point
From efficiency reduction, series excessively increases drag losses, and this provides reference for the design selection work of drier.
The soluble problem of the present invention has：One can prevent airflow passes tank, will not cause shadow to drier interior flow field
Ring；Two can independently collect moisture content of the corrugated sheet drier per the separation of one-level wall, study point at different levels of drier under different operating modes
From ability.

Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
With reference to Fig. 1 to Fig. 3, hydrophobic slot structure of the invention includes drain tank platform 1, and water trough body 2, tank dividing plate 3 is dredged
Water hole 4, hydrophobic conduit 5, corrugated sheet body 6.Drain tank is embedded in sink deck, corrugated sheet plate stand on drain tank platform it
On, the liquid film that corrugated sheet wall declines is collected completely by drain tank.Drain tank is divided into several compartments by tank dividing plate, respectively every
Between between do not connect mutually, the number of compartment is identical with the flanging number of corrugated sheet, corrugated sheet each flanging one tank of correspondence every
Between, it is communicated with a hydrophobic conduit, the moisture content that the flanging on separates hydrophobic in each compartment for exporting below each separate compartment
In tank compartment immediately below inflow, drain and collect by the hydrophobic conduit below the tank.
The hydrophobic slot structure of the present invention can use unlike material according to experimental situation difference, and the structure is used for hot steam-water
It is made during experiment of corrosion-resistant and high-temperature resistant materials such as stainless steels, transparent organic glass can be used when being tested for cold conditions Air-Water
Glass is made, and is illustrated below using hot material：Drain tank platform is opened a rectangle hole slot in the middle of one block of horizontal metal plate and is made,
Water trough body is rectangular groove structure, and size is consistent with the rectangle hole slot at sink deck center, and tank panel is in sink deck, water
Groove plane is concordant with sink deck plane.Tank dividing plate is made up of metal sheet piece, and fixed placement separates tank in tank
For some independent compartments, the number of compartment is identical with the flanging number of corrugated sheet, Hu Bu UNICOMs between each compartment, structure resistance
Every air-flow and the hydrophobic circulation in drain tank.Hydrophobic conduit is made up of stainless steel material, and hydrophobic conduit is circular tube structure, connection
In the bottom of drain tank separate compartment, the water that drain tank compartment bottom is provided with aperture, compartment enters hydrophobic conduit from aperture
It is exported and is imported into collection device.
The invention discloses a kind of hydrophobic slot structure for being used to study corrugated sheet drier separating capacities at different levels, it can be applied
The research field of the corrugated sheet drier used in station boiler and nuclear steam generator.The hydrophobic slot structure includes tank
Platform, tank, tank dividing plate, weep hole, hydrophobic conduit.Corrugated plate separating element is placed on above drain tank vertically, in drying
During device experimental study, the drop in steam water interface, which strikes corrugated sheet wall and formed, pools liquid film after big drop, liquid film edge
Wall to drop in drain tank.Drain tank is divided into some independent compartments, compartment number and corrugated sheet flanging number by dividing plate
Unanimously, each compartment is not connected mutually.Via hydrophobic below each compartment in the separate compartment of the hydrophobic entrance drain tank of drier wall
Hole enters in hydrophobic conduit weighs in runner collection vessel.The hydrophobic slot structure can independently collect each flanging point of corrugated sheet
