[0002] The working principle of a modular membrane separation nitrogen dryer is based on the difference in permeability of gas molecules within a polymer membrane material. When compressed air passes through the membrane separation module, smaller molecular weight gases (such as oxygen and water molecules) diffuse rapidly through the membrane material to the low-pressure side, while larger molecular weight nitrogen molecules accumulate on the high-pressure side due to their slower permeation rate. Simultaneously, the membrane separation process also separates impurities such as water vapor, resulting in dry, high-purity nitrogen.

However, their electrical control systems are often the same as those of conventional dryers. Operators are unaware of malfunctions in the nitrogen generator or when the nitrogen concentration or dew point fails to meet standards. Therefore, based on these shortcomings of existing dryers, improvements to their electrical control systems are necessary. Utility Model Content
