Intelligent seawater concentration control method of circulating spraying heat exchange system

Abstract

The invention provides an intelligent seawater concentration 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 seawater is sprayed to the evaporator; a seawater concentration detector is arranged in the tank body, and is used for detecting the concentration of seawater, and a controller automatically controls seawater drainage according to the detected seawater concentration; and if the measured seawater concentration exceeds a certain value, the controller controls the circulating spraying pump to stopworking, a wastewater outlet at the lower part of the tank body is opened, and strong brine is discharged from the wastewater outlet. The intelligent seawater concentration control method can realizeintelligent control of the drainage and inflow 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 ...

Problems solved by technology

[0005] There are more than 10,000 islands in China, but most of them are uninhabitable due to lack of fresh water, and there are less than 500 permanent residents, which restricts the functions of island development and national defense.
