The shell-and-tube heat exchanger For shell and tube heat exchangers, a problem that is easily ignored is the vibration of heat exchange tubes. And the vibration of heat exchange tube bundle is often the destruction of heat exchange tube. The position of the heat exchange tube vibration is wide, can be a certain two baffle between all the heat exchange tube vibration at the same time, or only a few rows of heat exchange tube vibration. It may also be in the medium inlet or outlet end of some heat exchange tube vibration. In short, the vibration of the heat exchange tube may occur in any one or more places of the heat exchange tube bundle.

The main reason for the premature scrap of heat exchanger
There are many and complex factors causing the vibration of heat exchange tube. When the medium flow is close to the critical flow rate of resonance, the heat exchange tube bundle will produce large vibration. In addition, local turbulence and eddy currents in the internal medium of heat exchanger will also cause vibration of heat exchange tube.
The vibration analysis of the tube bundle of heat exchanger is to determine the vibration position and vibration properties of the heat exchange tube, to understand the cause of the vibration of the heat exchange tube, so as to eliminate the vibration of the heat exchange tube. There are many ways to eliminate the vibration of the heat exchange tube. The natural frequency of the heat exchange tube bundle or the flow state of the fluid can be changed by changing the structure size of the heat exchanger, so as to eliminate the vibration of the heat exchange tube. Or add local support plate to the vibration part of the heat exchange tube bundle to restrain the vibration of the heat exchange tube.
Features
- 1). Determine the required heat exchange area according to the known flow rates of cold and hot fluids, the initial and final temperatures, and the specific heat capacity of the fluid.
- 2). When selecting a heat exchanger, pay attention to the pressure level, the operating temperature, and the connection conditions of the interface. Under the premise of pressure drop and installation conditions, the shell-and-tube heat exchanger can be used to increase the heat exchange capacity by using a lengthening type with a small diameter.
- 3). The pressure drop of the heat exchanger should not be too large, generally controlled between 0.01 and 0.05 MPa;
- 4). The flow rate should take into account the viscosity of the fluid, the flow rate of the viscosity should be less than 0.5 ~ 1.0m / s; the flow rate in the general fluid tube should be 0.4 ~ 1.0m / s;
