Abstract
Description
본 발명은 화력 발전소의 발전기에 있어서, 발전기의 스테이터(stator)를 냉각하기 위한 냉각 시스템의 냉각수 탱크 내에 와류(vortex)가 형성되는 것을 방지하기 위한 장치에 관한 것이다.The present invention relates to an apparatus for a thermal power plant, the apparatus for preventing the formation of vortex in the cooling water tank of the cooling system for cooling the stator of the generator.
화력이나 원자력 발전소의 발전기에 있어서, 그 보조기기 계통에 속하는 스테이터 냉각수 시스템에는 냉각수 저장 탱크가 필연적으로 구비된다. 상기 냉각수 저장 탱크로부터 냉각수를 순환시키기 위해서 펌프가 사용된다.In a generator of a thermal power plant or a nuclear power plant, a coolant storage tank is necessarily provided in a stator cooling water system belonging to the auxiliary system. A pump is used to circulate the cooling water from the cooling water storage tank.
상기 펌프가 원심 펌프인 경우, 저장 탱크 내의 펌프 연결관에는 와류가 형성되기 쉬운데, 탱크의 수위가 낮아질수록 와류에 의해 상기 펌프로 유입되는 냉각수의 압력이 작아지고 상기 펌프에 캐비테이션(cavitation)을 일으키기 쉽게 되는 문제점이 있다. 펌프에 캐비테이션이 발생하면 펌프가 고장을 일으켜 멈추게 되고 보조 펌프 또는 여분의 펌프를 사용하여야 하는데, 이 보조 펌프의 경우에도 같은 캐비테이션의 위험에 노출된다. 연결된 펌프가 모두 작동을 멈추게 되면 전체 발전소의 동작을 멈춰야 하는 만큼 이에 대한 대책이 필요하였다.When the pump is a centrifugal pump, a vortex is easily formed in the pump connection pipe in the storage tank. As the water level of the tank is lowered, the pressure of the coolant flowing into the pump by the vortex becomes smaller and causes cavitation to the pump. There is a problem that becomes easy. If cavitation occurs in the pump, the pump will fail and stop and you will have to use an auxiliary pump or a spare pump, which is also at risk of cavitation. If all connected pumps stopped working, the whole plant had to shut down.
본 발명의 목적은 냉각수 탱크로부터 펌프로 유입되는 냉각수의 압력을 떨어뜨리는 원인이 되는 와류의 형성을 억제할 수 있는 장치를 개발하는 것이다.It is an object of the present invention to develop an apparatus capable of suppressing the formation of vortices which causes the pressure of the cooling water flowing into the pump from the cooling water tank.

도 2는 본 발명에 따른 탱크 내의 와류 형성 방지 장치를 구성하는 와류 방지판과 받침대의 일실시예를 보여주는 사시도.Figure 2 is a perspective view showing an embodiment of the vortex preventing plate and the pedestal constituting the vortex forming prevention device in the tank according to the present invention.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
도 1에는 본 발명에 따른 탱크 내의 와류 형성 방지 장치가 설치된 저장 탱크의 도면이 도시되어 있다.1 shows a view of a storage tank in which an apparatus for preventing vortex formation in a tank according to the present invention is installed.
도 1에 도시된 것과 같이, 저장 탱크(1)의 하부에 원심 펌프로 연결되는 펌프 연결관(3 또는 4)이 배치되어 있는 경우, 상기 연결관(3 또는 4)의 입구에 본 발명에 따른 와류 형성 방지 장치(6)를 설치함으로써 와류의 형성을 억제할 수 있다.As shown in FIG. 1, when the pump connection pipe 3 or 4 is arranged at the bottom of the storage tank 1, which is connected by a centrifugal pump, the inlet of the connection pipe 3 or 4 according to the invention. The formation of the vortex can be suppressed by providing the vortex formation preventing apparatus 6.
도 2에는 본 발명에 따른 와류 형성 방지 장치의 사시도가 도시되어 있다.2 is a perspective view of a vortex forming prevention device according to the present invention.
도 2에 도시된 것과 같이, 본 발명에 따른 와류 형성 방지 장치(6)는, 중심축에 용접에 의해 60도의 각도를 이루면서 결합되는 6개의 직사각형의 판재들로 구성되는 와류 방지판(8)과, 상기 와류 방지판(8)의 하부에 결합되는 탱크 저면의 곡면 형상에 맞춰 곡선으로 형성되는 받침대(7)로 구성된다.As shown in Fig. 2, the vortex forming apparatus 6 according to the present invention includes a vortex preventing plate 8 composed of six rectangular plate members joined to form an angle of 60 degrees by welding to a central axis. It is composed of a pedestal (7) formed in a curve in accordance with the curved shape of the bottom surface of the tank coupled to the lower portion of the vortex preventing plate (8).
