<P>PROBLEM TO BE SOLVED: To provide an energy recovery apparatus which prevents the occurrence of a rapid change in the pressure of high-pressure concentrated seawater 4 by switching the force feed process and filling process for two cylinder devices 7a and 7b. <P>SOLUTION: The two cylinder devices 7a and 7b are made to communicate with two channel switching devices 20a and 20b, respectively, each of first and second position detectors 30a and 30b detecting the transfer passage of pistons 8a and 8b is located on one end side of each of the two cylinder devices 7a and 7b, and each of third and fourth position detectors 31a and 31b is located on one side closer to the end with an interval kept. The cylinder device in the filling process by the channel switching devices 20a and 20b is made the force feed process by the signals of the first and second position detectors 30a and 30b of the cylinder device of the force feed process. After that, the cylinder device in the force feed process by the channel switching devices 20a and 20b is made the filling process by the signals of the third and fourth position detectors 31a and 31b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
