Description

Technical Field

[0001] This utility model relates to the technical field of natural gas adsorption separation devices, specifically a natural gas adsorption separation device based on carbon-based MOF composite materials. Background Technology

[0002] During the extraction, storage, and transportation of natural gas, various impurities are typically present, including carbon dioxide, water vapor, sulfides, nitrogen, and heavy hydrocarbons. These impurities not only reduce the calorific value and combustion efficiency of natural gas, leading to energy waste, but can also cause a series of equipment problems. The presence of carbon dioxide and water vapor can easily form acidic gases at low temperatures, causing corrosion of pipelines and storage tanks, increasing equipment maintenance costs, and shortening their service life.

[0003] Existing natural gas adsorption separation devices mostly adopt a fixed adsorption layer structure, and their internal materials are mostly single-type adsorption media. The maintenance and replacement process is complicated, and the adsorption efficiency is greatly affected by the gas flow path and material structure. In some devices, during long-term operation, due to insufficient sealing of the adsorption layer or loose structure, gas leakage and adsorption failure are prone to occur, affecting the stability of the device.

[0004] Therefore, it is necessary to design a natural gas adsorption and separation device based on carbon-based MOF composite materials to solve the above problems. Utility Model Content

A slot is opened on one side of the inlet pipe 1, and a plug ring 12 is slidably inserted into one side of the vent pipe 2. A ring groove is provided on one side of the pipe 1, and a carbon-based MOF composite material sheet 15 is embedded inside the ring groove. A sliding block 13 is fixedly connected to one side of the insert ring 12, and an insert block 11 is fixedly connected to one side of the sliding block 13.

The threaded end of the inlet pipe 1 is connected to the natural gas supply pipe, and the threaded end of the vent pipe 2 is connected to the purified natural gas outlet. By using the opening of the servo motor 5, the fit between one end of the rotating block 9 and the sliding block 13, as well as the gate 17 inside the inlet pipe 1, is adjusted to open and close the rotating gate 17, thereby facilitating the maintenance and replacement of the carbon-based MOF composite material sheet 15.

[0021] To improve the stability of the sliding insertion of the insertion ring 12 on one side of the vent pipe 2, the drive mechanism includes a servo motor 5, which is fixed to the top of the device box 4. One end of the second rotating shaft 16 is fixed to the output shaft of the servo motor 5.

[0022] In order to improve the sealing performance of the insert ring 12 when it is inserted into the intake pipe 1, a sealing ring 14 is fixed to one end of the sliding block 13 on one side of the carbon-based MOF composite material sheet 15, and the sealing ring 14 is in contact with one side of the carbon-based MOF composite material sheet 15.
