On the distillation tray, the saturated liquid with lower temperature and the saturated steam with higher temperature are fully contacted on the tray. The saturated steam emits heat to the saturated gas, and partially condenses. Oxygen is a high boiling point component, so more condensation is caused by the gradual increase of the concentration of oxygen in the high boiling point component of the liquid; Saturated liquid absorbs heat and partially evaporates, while nitrogen is a low boiling point component, so it evaporates more and enters the gas phase, gradually increasing the nitrogen content of the low boiling point component in the gas. Finally, oxygen and nitrogen separation will be realized.

The general manufacturing process of air separation equipment is raw material cutting, rounding, welding, rounding and assembly. Rounding is one of the simpler and more difficult processes. The simplicity lies in that the process only needs to roll the rectangular plate into a cylinder; The difficulty lies in how to ensure its roundness reaches the standard. Now, a new type of equipment has brought new changes to this work. Kaifeng DEAR Air Separation uses the original dual-servo four-roller fully automatic plate bending machine on its production line, which realizes the process requirements of high rounding accuracy and small misalignment error, and greatly improves the rounding speed and quality.
