Rapid drainage device and method for fuel pool
The invention discloses a rapid drainage device and method for a fuel pool. The rapid drainage device for the fuel pool comprises a drainage pipe, a drainage control valve, an air extractor and an air extraction pipe; the first end of the drainage pipe is used for stretching into the fuel pool; the drainage control valve is connected to the second end of the drainage pipe and controls on-off of the drainage pipe or adjusts the drainage flow of the drainage pipe; the air extraction pipe is connected between the second end of the drainage pipe and the air extractor; and the air extractor extracts air in the drainage pipe through the air extraction pipe, water in the fuel pool enters the drainage pipe, and inverted siphon is established. According to the rapid drainage device and method for the fuel pool, the air extractor extracts air in the drainage pipe to form inverted siphon, water in the fuel pool is drained through the siphon effect, rapid online water changing is achieved, air extraction does not need to be conducted beside the fuel pool, the risk that foreign matter is introduced into the fuel pool is avoided, the personnel falling risk and the operation risk in the fuel pool are avoided, and tests such as a PTR system flushing test, a cooling pump performance test and a purification test are smoothly conducted.
本发明公开了一种燃料水池快速排水装置及燃料水池快速排水方法，燃料水池快速排水装置包括排水管、排水控制阀、抽气器以及抽气管；排水管的第一端用于伸进燃料水池内；排水控制阀连接在排水管的第二端上，控制排水管的通断或调节排水管的排水流量；抽气管连接在排水管的第二端和抽气器之间；抽气器通过抽气管将排水管内部的空气抽出，使燃料水池内的水进入排水管，建立倒虹吸。本发明通过抽气器对排水管抽气形成倒虹吸，以虹吸效应将燃料水池内的水排出，实现快速在线换水，无需在燃料水池边进行抽气，避免了向燃料水池内引入异物的风险，无人员坠落风险及燃料水池内作业风险，保证PTR系统冲洗试验、冷却泵性能试验、净化试验等试验顺利进行。
