Technical Field
[0001] This utility model relates to the field of natural gas dehydration technology, specifically a natural gas dehydration device with a quick-replacement polymer separation membrane. Background Technology
[0002] During the extraction and transportation of natural gas, it often contains impurities such as saturated water vapor. If it is not dehydrated, the water vapor will condense into liquid water at low temperatures and form hydrates with hydrocarbons in the natural gas, leading to pipeline blockage, equipment damage, and even safety accidents. Therefore, it is particularly important to develop a natural gas dehydration device that allows for rapid replacement of polymer separation membranes.
[0003] A natural gas dehydration device, as described in reference announcement number CN205886417U, includes a separation cylinder, an inlet pipe, an outlet pipe, and an external rotor motor. The inlet pipe is connected to the separation cylinder and is used to introduce the natural gas to be dehydrated into the inner cavity of the separation cylinder. The outlet pipe is also connected to the separation cylinder and is used to discharge the dehydrated natural gas from the inner cavity of the separation cylinder. The external rotor motor is located inside the separation cylinder and drives the natural gas to centrifugal motion through the rotation of its blades. This solution addresses the problems of low dehydration efficiency and large footprint in current natural gas dehydration devices. However, while this device can be widely used, it is generally inconvenient to disassemble the dehydration components, making disassembly and maintenance difficult and causing some inconvenience during use. Further improvements are needed. Utility Model Content

The outer wall of the contact plate squeezes and dehydrates the polymer separation membrane, thereby allowing the water inside the polymer separation membrane to flow quickly into the bottom of the dehydration tank to ensure the dryness of the polymer separation membrane and thus ensure the dehydration effect of the polymer separation membrane on natural gas.
