Attention to operation of tubular heat exchanger

Tubular heat exchanger is a kind of heat exchanger widely used in the production of chemical industry at present We need to pay attention to the following points in the operation to ensure the normal production of the equipment
1 If the temperature of two different fluids of the tubular heat exchanger is very different when it is working, then if the structure of the tubular heat exchanger is rigid, we need the fluid with higher heat transfer coefficient to pass through the shell side of the tubular heat exchanger during convection operation, so that the thermal stress can be effectively reduced and the tubular heat stress can be reduced at the same time Type heat exchanger in the work of the wear, to ensure that can work normally for a long time 2 If the flow rate of the fluid applied to the tubular heat exchanger is very small, and the viscosity of these fluids is very large, then in order to work effectively, we need to pass these fluids directly through the shell side of the tubular heat exchanger 3 If the main purpose of the thermal fluid of the tubular heat exchanger is to conduct cooling operation, and the temperature of the inlet and outlet of these thermal fluid has met the requirements of the production process of the tubular heat exchanger, then the size of the temperature of the outlet of the cooling medium needs to be selected according to the actual situation For example If the outlet temperature is relatively high, we need to choose a small tubular heat exchanger, but the flow of cooling medium needs to be increased accordingly 4 If the outlet temperature is relatively low, then we need to choose a large tubular heat exchanger and the flow of cooling medium also needs to be correspondingly reduced Therefore, when selecting, we need to measure the specific cooling medium according to the outlet temperature.
