Zusammenfassung:	The invention relates to the technical field of energy recovery, in particular to a fluid pressure energy recovery device and a seawater desalination system. The fluid pressure energy recovery device comprises N conversion units, wherein N is an even number greater than or equal to 2; the conversion unit is provided with a cylinder body and a piston assembly; the cylinder body is provided with a first cavity and a second cavity; the piston assembly is provided with a first piston and a second piston which are linked; the first piston is arranged in the first cavity and divides the first cavity into a first accommodating cavity and a second accommodating cavity; the second piston is arranged in the second cavity and divides the second cavity into a third containing cavity and a fourth containing cavity. The first containing cavity, the second containing cavity, the third containing cavity and the fourth containing cavity are sequentially arranged in the movement direction of the piston. The first containing ca
