Description

Technical Field

[0001] The utility model relates to the technical field of deep cold separation, in particular to a methane tower deep cold separation device. Background Art

[0002] The methane cryogenic separation device utilizes the different boiling points of the components in the raw gas to separate methane through physical cooling. The main components of the gas after washing with low-temperature methanol are hydrogen, carbon monoxide, nitrogen, and methane, among which methane has the highest boiling point, followed by carbon monoxide, and nitrogen and hydrogen have low boiling points.

[0003] For example, the "A Deep Cold Separation Device Based on a Demethanizer" with publication number CN215864305U includes a junction box, and a plurality of mounting grooves distributed in a circular array are provided on the upper surface of the junction box. A heat exchanger adapted to the mounting groove is provided in the inner cavity of the mounting groove. The upper end of the heat exchanger passes through the upper inner cavity of the mounting groove and extends to the top of the junction box. A groove is provided on the inner side wall of the mounting groove. A fixed pipe is fixedly connected to the bottom of the groove. An annular rubber pad is fixedly sleeved on the upper end of the outer wall of the fixed pipe. A heat exchanger adapted to the mounting groove is provided. A collecting tube is provided above the junction box. The inner cavity of the collecting tube is connected to the inner cavities of multiple heat exchangers through multiple hoses. Therefore, the space occupancy rate can be effectively improved and the volume of the entire heat exchange component can be reduced.

[0004] Although the above separation device has certain advantages in reducing the device space, it still has certain disadvantages:

[0005] When the above-mentioned separation device is used to extract methane, the heat exchanger used cannot adjust the temperature inside the heat exchanger, so it is easy for the temperature inside the heat exchanger to drop after use. The low temperature can easily affect the subsequent extraction effect, and it is impossible to ensure long-term operation, which reduces work efficiency. Utility Model Content
