Embodiment Construction

[0033] 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.

[0034] As a preference, diagram 2-1 The heat exchange component extends along the horizontal direction. The heat exchangers are arranged horizontally.

[0035] Figure 2 shows a top view of the heat exchange component 23, as shown in Figure 2, the heat exchange component includes a ...

Abstract

The invention provides a heat exchanger with four-fluid temperature cooperative communication memory control. The heat exchanger is characterized in that 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 temperature data of a first temperature sensor, a second temperature sensor and a third temperature sensor are stored in a database in real time, a one-dimensional deep convolutional neural network is adopted to extract data features, and mode recognition is carried out, so that opening and closing of the first valve, the second valve and the third valve are controlled, and therefore, whether first fluid, third fluid and second fluid exchange heat or not is controlled. According to the heat exchanger with four-fluid temperature cooperative communication memory control, based on a theoretical method of machine memory and mode recognition, detection and judgment results are more accurate.

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...
