Power generation device and method using organic working fluid for circulation without pump and valve

A power generation device using organic working fluid for circulation without pump and valve, the device comprising a flash injection tube (1), a magnetic sphere motion tube (2), a storage tank (3), a working fluid descent tube (4), a lower nozzle (5), a lower magnetic sphere (6), an upper nozzle (7), an upper magnetic sphere (8), a conical expansion part (9), a finned tube (10), a heat source (11), a linear generator coil (12), a rectifier circuit (13), a load (14) and a concentric outer tube (15), wherein the flash injection tube (1), the magnetic sphere motion tube (2), the conical expansion part (9), a lower portion of the storage tank (3) and the working fluid descent tube (4) are connected with each other in sequence to form a main loop;

• an upper portion of the storage tank (3), the finned tube (10) and the lower portion of the storage tank (3) are connected with each other to form a cooling loop;
• the lower nozzle (5) and the lower magnetic sphere (6) are provided at a lower end of the flash injection tube (1), which forms a one-way valve to restrict fluid to move upwardly only;
• the upper nozzle (7) and the upper magnetic sphere (8) are provided at an upper end of the flash injection tube (1), which forms a flash nozzle to drive the upper magnetic sphere (8) to move upwardly through the fluid;
• the upper magnetic sphere (8) is able to move in the magnetic sphere motion tube (2);
• the flash injection tube (1) and the concentric outer tube (15) form a tube and shell heat exchanger;
• the heat source (11) is used to provide shell side fluid of the tube and shell heat exchanger and transfer heat to tube side fluid to cause fluid flashing;
• the conical expansion part (9) is provided at an upper end of the magnetic sphere motion tube (2) away from the flash injection tube (1);
• the linear generator coil (12) is wound around the magnetic sphere motion tube (2), the linear generator coil (12) is connected with the rectifier circuit (13), the rectifier circuit (13) is connected with the load (14);
• the upper magnetic sphere (8), the magnetic sphere motion tube (2), the linear generator coil (12) and the rectifier circuit (13) form a linear generator.
