Principle of oxygen generator

The liquid oxygen pump is a kind of low temperature liquid pump. It is used as the liquid oxygen circulating pump in the main condensing evaporator in the internal compressed air separation process to increase the pressure of liquid oxygen and output liquid oxygen.

Nitrogen-water precooler is generally installed in all low-pressure air separation plant. It mainly uses the unsaturation of the water in the nitrogen to make part of the water evaporate. When the water evaporates, it absorbs the latent heat of vaporization to lower the cooling water temperature, and then uses it to cool the processed air to lower the air temperature entering the tower. Therefore, it includes air cooling tower and water cooling tower. The fundamental purpose of setting nitrogen-water precooler is to reduce the temperature of air entering the air separation tower and avoid the sharp fluctuation of the temperature entering the tower. Because the air temperature in the tower directly affects the working condition of switching heat exchanger and distillation column and the economy of the whole air separation plant. When designing, the temperature of air entering the tower is generally set at 30℃. When the inlet temperature of the tower is higher than the design index du...
