The Analysis And Simulation Of Temperature Field And Stress Field In An Oil Slurry Heat Exchanger

Oil slurry heat exchanger is one of the most important equipments in chemical industry. Its function is to lower the temperature of oil slurry by using cooling water. It is necessary and significant for the economic and security to analysis both temperature field and stress field of the oil slurry heat exchanger. It is also very important to analysis for sealed used in oil slurry heat exchanger, for the sake of saving materials and energy.Oil slurry heat exchanger belongs to tube-sheet heat exchanger. Due to its complex structure and large geometry size, it is too complicated to calculate on PC by using the finite elements of the whole equipment model. So tubesheet-pipes' temperature stress field and flange-gasket-bolts' temperature stress field are respectively analyzed, and seal function of the exchanger is also researched.Specifically speaking, use suitable stress analysis elements and thermal analysis elements applied by the ANSYS software to establish the suitable FEA model for calculating on PC. Use thermal analysis element SOLID 70, load convection heat transfer coefficient, calculate and obtain the temperature field of tubesheet-pipes of oil slurry heat exchanger, then use stress analysis element SOLID 45, bring pressure and temperature results to bear on areas of tubesheet and pipes, calculate and obtain the stress field of tubesheet-pipes of oil slurry heat exchanger; Use thermal analysis element SOLID 70, load convection heat transfer coefficient, calculate and obtain the temperature field of flange-gasket-bolts of oil slurry heat exchanger, then use stress analysis element SOLID 45, contact analysis element TARGE 170 CONTA174 and pre-tightened element PRETS179, bring pressure and temperature results to bear on areas of flange-gasket-bolts, calculate and obtain the stress field of flange-gasket-bolts of oil slurry heat exchanger. Lastly the seal function of the exchanger will be researched.
