[0002] The process of removing gas from liquid by degassing membrane technology has been widely used in the fields of removing CO2 and O2 in water. Degassing membrane devices have replaced vacuum degassing towers, blast degassing towers, degassing towers, degassing tanks and deoxidizers for more than 25 years. Degassing membrane technology is also widely used in the degassing of liquids in the fields of semiconductors, pharmaceuticals, electricity, food, beverages, industry, imaging, inks and printing inks.

[0003] However, the storage of the degassing membrane after contact with water requires the degassing membrane to be blown dry and stored to prevent bacterial contamination or damage to the membrane performance in the presence of water. However, the existing drying method takes a long time and is inefficient. If the environment is relatively humid, it cannot achieve a high drying effect. The existing method of drying the degassing membrane is usually to blow compressed air into the membrane filaments to dry the degassing membrane, but this method requires a long time to blow and has high energy consumption.

[0004] Therefore, the present application proposes a dehydration and drying device which can quickly dry a degassing membrane and has low energy consumption. Utility Model Content

DETAILED DESCRIPTION

[0024] As a preferred embodiment of the utility model, it may also have the following additional technical features: the filter assembly 2 includes a filter, and the exhaust port of the filter is connected to the air inlet 4. In this way, dust and oil mist in the air can be removed.

[0025] In this embodiment, a first flow meter 11 is installed between the first gas outlet pipe 8 and the degassing membrane 10, and a second flow meter 12 is installed between the second gas outlet pipe 9 and the drying membrane 3. Thus, it is convenient to control the flow rate of gas to dry the drying membrane and the degassing membrane.

[0026] In this embodiment, the second gas outlet pipe 9 is connected to the side of the drying film 3 containing the humidified gas, thereby facilitating the rapid drying of the drying film.

[0027] In this embodiment, the pressure regulating assembly includes a pressure regulating valve 13 for regulating the operating pressure of the drying membrane 3, and a pressure gauge 14 for detecting the pressure is installed between the pressure regulating valve 13 and the drying gas outlet 5. Thus, the drying gas is pressurized, and the water vapor after passing through the membrane can be taken away faster, thereby improving the drying efficiency of the drying membrane.

[0028] In this embodiment, the air inlet 4 is arranged at the bottom of the drying membrane 3, and the drying gas outlet 5 is arranged at the top of the drying membrane 3; the purge gas inlet 6 and the tail gas outlet 7 are arranged at the side of the drying membrane; the purge gas inlet 6 is located above the tail gas outlet 7.

[0029] The working principle of the utility model is as follows: the air compressor 1 sucks in the air from the environment to obtain compressed air that has not been dehydrated and dried. The compressed air enters the dust and oil removal filter. The filter removes dust and oil mist in the compressed air. The purified compressed air enters the drying membrane 3. Under the action of pressure, the water vapor in the compressed air preferentially passes through the membrane, and the outlet of the membrane obtains the dried compressed air. There is a pressure gauge at the outlet of the compressed air to detect the use pressure, and the pressure is adjusted by the pressure regulating valve to adjust the operating pressure of the drying membrane. After the pressure regulating valve, the gas is divided into two paths. One path of gas enters the gas flow meter with a valve and then enters the degassing membrane for purge and drying. The other path of gas also enters a gas flow meter with a valve and then enters the wet gas side of the drying membrane. The dry gas is under pressure, which can take away the water vapor that passes through the membrane faster, thereby improving the drying efficiency of the drying membrane.
