Heat exchanger controlled by cooperative communication of liquid level vibration

Abstract

The invention provides a heat exchanger controlled by cooperative communication of liquid level vibration. Inlets of a first heat exchange tube, a second heat exchange tube and a third heat exchange tube are provided with a first valve, a second valve and a third valve respectively; and liquid level data of a first liquid level sensor, a second liquid level sensor and a third liquid level sensor is stored in a database in real time, a one-dimensional deep convolutional neural network is adopted for extracting data features, and pattern recognition is conducted, so that opening and closing of the first valve, the second valve and the third valve are controlled, and thus whether a first fluid, a third fluid and a second fluid exchange heat or not is controlled. According to the heat exchanger controlled by cooperative communication of liquid level vibration, based on a theoretical method of machine memory and pattern recognition, detection and judgment results are more accurate.

Description

Technical field [0001] The present invention relates to a shell and tube heat exchangers, particularly to a batch type vibration cleaning shell and tube heat exchanger. Background technique [0002] The present invention relates to a heat exchanger fouling, on the basis of the research and development of Qingdao University of Science (Application No. 2019101874848) for use in the invention is a new shell and tube heat exchanger. [0003] Shell and tube heat exchangers are widely used in chemical, petroleum, refrigeration, nuclear power and other industries, due to the global energy crisis, in order to reduce energy consumption, industrial production, demand for more and more of the heat exchanger, quality requirements for heat exchangers are also increasing. In recent decades, although the compact heat exchanger (plate, plate-fin, plate heat insulation, etc.), the heat pipe heat exchanger, direct contact type heat exchangers, etc. have been developed rapidly, but the envelope 70 ...

Problems solved by technology

[0009] In the previous application, a shell-and-tube heat exchanger with heat exchange of four fluids has been developed, but the above-mentioned shell-and-tube heat exchanger is controlled according to the cycle, resulting in poor vibration heat exchange effect and partial intelligence. Low
