This reference to many data and the current of seawater desalination device used in the desalination technology。 The technology is now the most mature multi-stage flash technology combines solar collector technology for seawater desalination design。 This paper for the solar set hot single effect of multi stage flash seawater desalination device for calculation, verification, design, selection, installation, mainly the following aspects。

First, the study on the technology of seawater desalination and solar energy collection is made。 The principle and equipment of the two systems are analyzed in detail, and the calculation and design of the whole system are understood。

Second, according to the requirements of the design of multi stage flash seawater desalination part has carried on the preliminary design and the establishment of mathematical model, into the setting conditions, calculation, by calculating again for the preliminary design of the adjusted and completed stage devices at all levels of line selection and design of multi stage flash seawater desalination。

Third, according to the multi stage flash seawater desalination part of the design of the access to information and to evaluate the performance of the system。 Finally, solar set station and heat exchanger selection。

Fourth, the reference to complete the design of the two parts of the selection of pipe system, the two part of the combination, the completion of the design of the system equipment, and its final verification calculation。
