The invention provides a gas heat exchanger for heat exchange according to pressure. The left tube, the central tube and the right tube are respectively provided with a first pressure sensor, a second pressure sensor and a third pressure sensor for detecting the pressure of the left tube. , the pressure in the center pipe and the right pipe, the first pressure sensor, the second pressure sensor and the third pressure sensor are connected to the controller for data, and the controller controls the pressure according to the detected pressure of the left pipe, the right pipe and the center pipe Whether the first heat source, the third heat source and the second heat source are heated. The present invention proposes a rotationally symmetrical shell-and-tube heat exchanger for gas heat exchange. By detecting pressure changes in the left tube, right tube, and center tube, a new heat source is activated to perform alternate heat exchange, increasing the heat exchange effect and removing the heat. Dirt effect.
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...
