Embodiment Construction
[0071] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0072] In this article, if there is no special explanation, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.
[0073] like figure 1 A seawater desalination system is shown. The seawater desalination system includes an evaporation system, a condensation system and a freshwater collection system. The seawater is evaporated in the evaporation system to generate steam, and then the steam is condensed in the condensation system to become fresh water, and then the fresh water is collected through the fresh water system to collect.
[0074] The evaporation system includes a solar heat collector 1 and a loop heat pipe 2. The loop heat pipe 2 absorbs solar energy at the evaporation end, and then exchanges heat with seawater at the condensation end 8 to evaporate the seawater;
[0075] The condensation system inc...

The invention provides an intelligent water level control method of a circulating spraying heat exchange system. The system comprises a tank body, a circulating spraying pump, spray heads and a circulating pipeline arranged in the tank body, and the spray heads are arranged at the upper part of an evaporator; the circulating spraying pump pumps seawater into the spray heads, and then the seawateris sprayed to the evaporator; a water level detector is arranged in the tank body, and is used for detecting the height of seawater level in the tank body, and when the water level is less than a certain value, a controller automatically controls circulating spraying pump to stop working, and a water supplementing tube valve is opened to supplement water; and when the water level exceeds the certain value, the water supplementing tube valve is closed, and the circulating spraying pump starts to work. The intelligent water level control method can realize intelligent control of the drainage andinflow of the seawater, so the seawater is converted into freshwater to the maximum extent, and the maximum utilization effect is achieved.
Description
[0001] The present invention is a divisional application with the filing date of October 29, 2018, the application number 2018112674588, and the title of the invention "a circulating spray heat exchange system". technical field [0002] The invention relates to the fields of heat exchangers and seawater desalination, in particular to a plate-type condensing heat exchanger and a seawater desalination system thereof. Background technique [0003] Heat pipe technology is a heat transfer element called "heat pipe" invented by George Grover of Los Alamos National Laboratory in the United States in 1963. It makes full use of the principle of heat conduction and phase change medium. The rapid heat transfer properties of the heat pipe quickly transfer the heat of the heating object to the heat source, and its thermal conductivity exceeds that of any known metal. [0004] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced ...
