Problems solved by technology
[0006] In the application, it is found that continuous heating will lead to the formation of internal fluid stability, that is, the fluid is not flowing or has little fluidity, or the flow rate is stable, resulting in heat exchange tubes The vibration performance is greatly weakened, which affects the descaling of the heat exchange tube and the heating efficiency

Embodiment Construction
[0041] A shell-and-tube heat exchanger, such as figure 1 As shown, the shell-and-tube heat exchanger includes a shell 11, a heat exchange component 10, a shell side inlet connection 5 and a shell side outlet connection 6; the heat exchange component 10 is arranged in the shell 11, and the heat exchange component It is fixedly connected to the front tube sheet 14 and the rear tube sheet 17; the shell-side inlet connecting pipe 5 and the shell-side outlet connecting pipe 6 are both arranged on the shell 11; the fluid enters from the shell-side inlet connecting pipe 5 and passes through the heat exchange components. For heat exchange, take over the outlet 6 of the shell side to go out.
[0042] figure 2 Shows the cutaway schematic diagram of heat exchanging component 10 (from figure 1 observed on the left), such as figure 2 As shown, the heat exchange component 10 includes a right tube box 2, a left tube box 8 and a heat exchange tube 1, the heat exchange tube 1 communicates...

The invention provides a shell-and-tube heat exchanger with flow control induced vibration, the heat exchange components include a right tube box, a left tube box and heat exchange tubes, and the first heat exchange tube is arranged through the left tube box , the second heat exchange tube is set to pass through the right tube box; within a cycle time T, the flow rate of the fluid in the first heat exchange tube is V1, the flow rate of the fluid in the second heat exchange tube is V2, the controller controls V1, V2 intermittent of the flow. The present invention controls the intermittent flow of V1 and V2, on the one hand, it realizes the continuous heat exchange of the shell side process, and at the same time, it can also make the elastic heat exchange tube vibrate periodically and frequently, so as to realize good descaling and Heat exchange effect.
Description
technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a shell-and-tube heat exchanger with flow control induced vibration. Background technique [0002] This invention is a joint research and development project with Qingdao University of Science and Technology, which involves descaling of heat exchangers. Based on the research and development of Qingdao University of Science and Technology (application number 2019101874848), it is used for a new invention of shell-and-tube heat exchangers. [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 ...
