Working principle of cryogenic air separation equipment

  Flow state and heat transfer coefficient Fluid mechanics flow experiments tell us that the fluid flow state can be divided into laminar flow, turbulent flow and excessive flow, laminar flow of each flow beam in an orderly flow, will not interfere with other flow beam. In turbulent flow, the bundles are irregularly intertwined and interfere with each other. Excess flow is a state of flow between laminar and turbulent flow. Of these three flow sta...

In the air separation unit, the function of air cooling column is to reduce the temperature of air compressed by air compressor. Air cooling column is a kind of hybrid heat exchange equipment. In order to increase the heat transfer area, make the cooling water fully contact with the air and mix completely to enhance the heat transfer effect, the air cooling column usually adopts several structural forms such as packed column, sieve plate column or hollow spray column.
