Abstract
The invention discloses a liquid-gas separation structure and a water level detector guiding structure comprising the liquid-gas separation structure. The liquid-gas separation structure comprises a joint. A diversion device is connected to the joint. The joint and the diversion device are provided respectively with blind holes. The bottom of the diversion device is a closed end of the blind hole. A side of the diversion device is provided with multiple inclined holes. Two ends of each one of the inclined holes are located respectively on an inner surface and an outer surface of the diversion device. The level height of end openings of the inclined holes on the outer surface is higher than the level height of end openings of the inclined holes on the inner surface. The inclined holes form channels for coolant flowing from a core outlet to a support column so that the impact produced by a coolant at the core outlet on a water level detector is avoided. The bubble-containing coolant flowing out of the core outlet can flow upward along a diversion device side, orderly flow through the inclined holes inclining downward on the diversion device side and the blind holes and flow into the support column so that the water level detector is immersed. Bubbles do not enter into the support column by the inclined holes inclining downward so that liquid-gas separation of the coolant at the core outlet is realized.
Description
Technical field
The present invention relates to for the liquid gas separation structure of detector in nuclear reactor and the physical construction of guiding, specifically the water level detector guide frame of a kind of liquid gas separation structure and formation thereof.
Background technology
Because the nuclear reactor measuring system need to continue to monitor reactor pressure vessel water level key point under operating mode after accident or accident, need water level detector is introduced in reactor by suitable structure, and utilize the heat-transfer capability between water and steam to exist this principle of significant difference to realize the function that water level is measured.
The existing nuclear power reactor of pressurized water type dispersed placement, mostly adopt the guide frame that detector assembly cluster type integral body is drawn, this guide frame requires detector assembly to possess certain crooking ability, namely possess certain bending radius and angle of turn, require simultaneously reactor structure upper cover chamber to possess certain axial height.In addition, because water level detector end position is in core exit, and may be with bubble from the cooling medium of core exit outflow, if directly flow to water level detector, not carrying out liquid gas separates, this will affect the accuracy that water level detector is measured, and water level detector is formed and impacts, thereby affects the serviceable life of water level detector.
So limited for upper cover chamber axial height, can't arrange the reactor structure of cluster type detector assembly, the guiding that water level detector is introduced, protection all do not reach requirement, and liquid gas mixes and makes cooling medium impact water level detector.
Summary of the invention
The object of the present invention is to provide the water level detector guide frame that is applied to a kind of liquid gas separation structure and forms; solve the problem that present cluster type detector assembly can not be applicable to existing pressure vessel; the guide frame that design makes new advances, be used for introducing guiding, protection and the supporting of the single detector in heap.
