The present invention relates to a seawater desalination device, a seawater desalination method and a potion cleaning method. The seawater desalination device comprises a seawater introducing and filtering device and a seawater reverse osmosis filtering device. A first control valve is arranged between the filtering device after the introduction of seawater and the seawater reverse osmosis filtering device; and a second control valve is arranged at the end of pipeline of the seawater reverse osmosis filtering device. The seawater desalination device further comprises a control circuit. The seawater introducing and filtering device is consisted of a seawater inlet valve, a seawater pump and a filter which are communicated in turn via pipeline; the seawater reverse osmosis filtering device is consisted of the first control valve, a high-pressure pump, a reverse osmosis membrane group, a pressure regulating valve, the second control valve and a clean water tank which are communicated in turn via pipeline. By adopting the above structure, the seawater desalination device, the seawater desalination method and the potion cleaning method are controlled by a variety of combination of manual control and electronic control. And, seawater desalination stop cleaning step and potion cleaning step are reduced, the structure is simplified, and the efficiency is improved. |
