Close.The method of operation of ocean nuclear power platform is close with land based nuclear power plant, is adapted to the steam-water separation reheat machine using integration,
Steam-water separation reheat machine is by steam-water separator and the incorporated pressure vessel of reheater two parts.Steam divides into carbonated drink
After reheat machine, initially enter steam-water separator and be removed most of moisture, overheat shape is heated to subsequently into reheater
State.Using steam-water separation reheat machine, steam moisture on the one hand can be reduced, improves steam quality；On the other hand steamer can be increased
Unit efficiency, improve the economy of unit.
Ocean nuclear power platform is limited by space, and is needed considering marine environment (as tilted, waving, impacting)
Influence, volume and reliability to steam-water separation reheat machine propose higher requirement.Therefore, it is tight to design a kind of structure
Gather, runner is unobstructed and heat exchange efficiency is high marine vertical steam-water separation reheat machine it is very necessary.
Utility model content
The purpose of this utility model is to provide a kind of marine vertical vapour compact-sized, runner is unobstructed and heat exchange efficiency is high
Water separates reheat machine.
To achieve the above object, the utility model adopts the following technical scheme that：Marine vertical steam-water separation reheat machine, bag
Cylinder, upper cover and low head are included, it is characterized in that the upper and lower end of cylinder is connected to form vertical shell with upper cover and low head respectively
Body, steam inlet and steam (vapor) outlet are provided with cylinder, secondary side manhole is provided with upper cover, separation is provided with low head
Water outlet, the inner chamber of low head are in communication with the outside by separating water outlet, and steam inlet and steam (vapor) outlet are on cylinder
Axis is positioned opposite, and preseparator, corrugated sheet steam-water separation have been sequentially arranged from steam inlet to steam (vapor) outlet in housing cavity
Device and reheater, preseparator include support bar, water conservancy diversion conical ring and collecting ring, preseparator and are fixed on cylinder by support bar
Inwall, water conservancy diversion conical ring and steam inlet coaxial line, Shutter Steam Separator include Perforated plate, corrugated sheet group, drain tank and
Drain pipe, the upper end of drain pipe are connected with drain tank, and the lower end of drain pipe connects with the inner chamber of low head, and reheater is vertical knot
Structure, the top and bottom of reheater outside upper cover and low head, are provided with heating steam and entered respectively at the top of reheater
Mouthful, the bottom of reheater is provided with condensation-water drain.
Further, the steam inlet and steam (vapor) outlet are respectively two, and steam inlet and steam (vapor) outlet are respectively along housing
Axially up and down arrange.
Thin separator of the present utility model and it is hydrophobic use vertical structure, tilt and wave to steam-water separation and hydrophobic erect
Straight flow effect is smaller；Preseparator is set at device portal, and effectively uniform steam flow simultaneously isolates the drop being relatively large in diameter, and enters
And improve the separative efficiency and reliability of whole water separator；It is hydrophobic in reheater tube there is no water by gravity discharge
Accumulation without setting continuous steam discharge facility in tube bank, reduce the rate of air sucked in required of heating steam, improve the heat exchange of reheater
Efficiency.The utility model is compact-sized, runner is unobstructed.
