Relevant introduction of membrane compressed air dryer

The membrane dryer is a compressed air drying device that uses the difference in membrane permeability of compressed air to realize the separation of moisture from air and water, thereby obtaining dry compressed air to meet user requirements.

　　 membrane dryer has the advantages of stable performance, high reliability, small installation space, no power supply, and no influence of ambient temperature. The user can adjust the dew point of the air outlet according to the air demand to meet the needs of different working conditions. Compared with traditional dryers, the biggest advantage of membrane dryers is environmental protection and energy saving. They are mainly used in industrial control, medical technology, food processing, technical research laboratories and other terminal occasions. The membrane dryer is composed of hollow fiber ultrafiltration device, membrane group, membrane tube and other main components. Its inner wall is a membrane layer, which is combined with a sponge-like outer wall with coarse holes.

　　When compressed air passes through a special hollow fiber membrane, the different osmotic pressures of internal water vapor are used to separate air and water to obtain dry compressed air. This kind of dryer does not need to be controlled during work, does not consume electricity, does not consume energy, and is quite convenient to use. However, this permeable membrane is very sensitive to oil, so it is necessary to carry out multi-stage degreasing treatment on the air before inhalation. The dryer load is small and expensive.
