Embodiment Construction

[0038] A shell-and-tube heat exchanger, such as figure 1 As shown, the shell-and-tube heat exchanger includes a shell 20, a heat exchange component 23, a shell side inlet connection 21 and a shell side outlet connection 22; the heat exchange component 23 is arranged in the shell 20, and the heat exchange component It is fixedly connected to the front tube sheet 16 and the rear tube sheet 19; the shell-side inlet connecting pipe 21 and the shell-side outlet connecting pipe 22 are both arranged on the shell 20; the fluid enters from the shell-side inlet connecting pipe 21 and passes through the heat exchange components. For heat exchange, take over the outlet pipe 22 on the shell side to go out.

[0039] Preferably, the heat exchange component extends along the horizontal direction. The heat exchangers are arranged horizontally.

[0040] figure 2 A top view of the heat exchange component 23 is shown, as figure 2 As shown, the heat exchange component includes a central tube 8...

Abstract

The invention provides a heat exchanger achieving liquid level heat exchange control of four kinds of fluid. A first valve, a second valve and a third valve are arranged on an inlet of a first heat exchange pipe, an inlet of a second heat exchange pipe and an inlet of a third heat exchange pipe correspondingly. A first liquid level sensor, a second liquid level sensor and a third liquid level sensor are arranged in a left side pipe, a center pipe and a right side pipe correspondingly. A controller controls the first valve, a second valve and a third valve to be opened and closed according to the detected liquid levels of the left side pipe, the right side pipe and the center pipe, and therefore the first fluid, the second fluid and the third fluid are controlled to carry out heat exchangeor not. According to the heat exchanger, the first valve, the second valve and the third valve are controlled to be opened and closed according to liquid level detection; on one hand, constant heat exchange is carried out on a shell side in the process; and on the other hand, an elastic heat exchange pipe can periodically and frequently vibrate, and therefore a very good descaling and heat exchange effect is achieved.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a shell-and-tube heat exchanger with intermittent vibration descaling. Background technique [0002] The invention relates to descaling of heat exchangers, which is a new invention of shell-and-tube heat exchangers based on the research and development of Qingdao University of Science and Technology (application number 2019101874848). [0003] 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 d...
