Original title How much do you know about the types uses and principles of heat exchangers in the petrochemical industry At this stage in the petrochemical industry the application of heat exchanger is very extensive Next Xiaobian shares with you the types and use principles of heat exchangers in the petrochemical industry Heat pipe heat exchanger in petrochemical industry Generally the heat pipe heat exchanger is widely used in cbd crystallization equipment the harsh conditions of recovering waste heat in the petrochemical industry mainly including the production of high-sulfur fuels and other harsh conditions In the production process of petrochemical industry the key facilities are high-temperature heating and cracking facilities It is very economical and easy to achieve and the effect is very satisfactory especially for the high temperature smoke exhaust furnace the smoke exhaust temperature is high which is more superior The gas-liquid heat pipe heat exchanger inserts one end of the heat pipe from the exhaust end and each heat pipe decarboxylation after extraction is wound with fins on the pipe wall to increase the heat absorption surface
Compared with segmental baffles such baffles (called discontinuous helical baffles) can reduce the pressure drop by about 45% under the same working conditions while the overall heat transfer coefficient can be increased by 20% -30% and the size of the heat exchanger can be greatly reduced under the same heat load wiped film evaporator The difference between the spiral baffle heat exchanger and the ordinary shell-and-tube heat exchanger is that the baffles in the shell side are arranged in a spiral shape so that the medium in the shell side is spirally and continuously rotated from the inlet to the outlet and the traditional transverse baffle mode is changed into a longitudinal spiral baffle mode
At the same time in order to achieve a reasonable and economical heat exchanger the heat exchanger must be adjusted from the perspective of structural parameters It is not perfect to consider only the heat exchange area and margin Editor Sum up Being familiar with the types uses and principles of heat exchangers in the petrochemical industry can effectively avoid the premature damage of heat exchangers improve the energy efficiency of the petrochemical industry prevent unnecessary shutdown and avoid the loss of products caused by the problems of heat exchangers —————————————————————— Disclaimer The copyright of this article belongs to the original author If copyright is involved please contact to delete and return to Sohu to see more Responsible Editor toptiontech.com
