A submerged self-disturbing shell-and-tube heat exchanger

Abstract

The invention provides an immersed self-disturbing shell-and-tube heat exchanger. The heat exchanger includes a shell, a liquid separation device, a self-disturbing flow device and a liquid collecting device, and the shell is provided with a cooling liquid inlet. The cooling liquid inlet and the cooling liquid outlet are communicated with the liquid separation device, the liquid separation device is communicated with the self-disturbing flow device, and the liquid collecting device is located below the cooling liquid level on the upper part of the shell , the liquid collecting device is communicated with the cooling liquid outlet, and the cooling liquid enters the casing through the cooling liquid inlet, the liquid separation device and the self-disturbing device in turn, and passes through the liquid collecting device from the cooling liquid outlet. outflow, and the heat source is immersed in the cooling liquid in the shell; the liquid separation device includes a liquid separation mother pipe, and the liquid separation mother pipe is communicated with the cooling liquid inlet. The invention achieves the effect of automatic control to save energy by controlling the temperature of the liquid outlet, and enhances the disturbance intensity of the cooling liquid flow field in the casing. The higher the heat exchange efficiency.

Description

technical field [0001] The invention relates to the field of shell and tube heat exchangers, in particular to a submerged shell and tube heat exchanger. Background technique [0002] Shell-and-tube heat exchangers are widely used in chemical, petroleum, refrigeration, nuclear energy and power industries. Due to the worldwide energy crisis, in order to reduce energy consumption, the demand for heat exchangers in industrial production is also increasing. The quality requirements for heat exchangers are also getting higher and higher. In recent decades, although compact heat exchangers (plate, plate-fin, press-welded plate heat exchangers, etc.), heat pipe heat exchangers, direct contact heat exchangers, etc. have been developed rapidly, but due to the The heat exchanger has a high degree of reliability and wide adaptability, and it still occupies a dominant position in output and consumption. According to relevant statistics, the current consumption of shell-and-tube heat exc...
