Steady flow evaporator and seawater desalination system

Abstract

The invention provides a steady flow evaporator. The steady flow evaporator comprises an inlet header, an outlet header, and a heat exchange component connected between the inlet header and the outletheader, wherein the inlet header and the outlet header are respectively connected with a steam inlet pipe and a condensate outlet pipe; the steam inlet pipe of the inlet header is internally providedwith a flow stabilizer, and the flow stabilizer has a sheet structure; the sheet structure is arranged on the cross section of the steam inlet pipe; the flow stabilizer is formed by a square structure and a regular octagonal structure, so that a square through hole and a regular octagonal through hole are formed. The flow stabilizer with the novel structure is adopted, namely, a flow stabilizer in a loop heat pipe is subjected to field transfer and is applied to an inlet pipe at an evaporation end of the loop heat pipe, so that a water hammer phenomenon caused by the space expansion when a steam-water mixture enters the inlet header can be reduced.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a steady flow evaporator. Background technique [0002] Heat pipe technology was developed in Los Alamos, USA in 1963. national laboratory A heat transfer method called a "heat pipe" invented by George Grover element , it makes full use of the principle of heat conduction and the rapid heat transfer properties of phase change media, and quickly transfers the heat of the heating object to the heat source through the heat pipe, and its thermal conductivity exceeds that of any known metal. [0003] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air volume motors to obtain better heat dissipation. The use of heat pipe technology enables the radiato...

Problems solved by technology

[0004] 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.
