Loop heat tube heat exchanger capable of switching heat sources to heat gas

Abstract

The invention provides a loop heat tube heat exchanger capable of switching heat sources to heat gas. A first liquid level sensor, a second liquid level sensor and a third liquid level sensor are correspondingly arranged in a left side tube, a central tube and a right side tube and are used for detecting liquid levels in the left side tube, the right side tube and the central tube; and the first liquid level sensor, the second liquid level sensor and the third liquid level sensor are in data connection with a controller, the controller extracts liquid level data of a left tube box, a right tube box and a middle tube box according to the time sequence, the liquid level data of adjacent time periods are compared to obtain the liquid level difference or accumulation of liquid level difference changes, and when the liquid level data are lower than a threshold value, the controller controls whether a first heat source, a third heat source and a second heat source conduct heating or not. According to the rotationally symmetrical gas heat exchange shell-and-tube heat exchanger, a new heat source is started to perform alternate heat exchange by detecting the liquid level difference change in the left side tube, the right side tube and the central tube, so that the heat exchange effect and the descaling effect are improved.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a shell-and-tube heat exchanger for gas heat exchange. 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...
