[0031] Working principle: when the low purity methane is condensed, first control the second motor 7 to rotate, and the outer rotating rod 14 will rotate 180 degrees under the drive of the synchronous belt 8. The rotating process will make the partition block 9 and the movable block rotate, so as to complete the separation between the cavities. Control the condenser 2 to work and set the temperature of the three cavities to-30℃, -80℃ and-160℃ respectively. Then, the gas is discharged from the inlet 3 into the first cavity. After a specified amount is discharged, the gas in the first cavity will be condensed for the first time. After a period of condensation, part of the mixed gas will be condensed, and the condensed liquid will flow into the collection tank 21. At this time, control the first motor 6 to rotate, and the inner rotating rod 17 will rotate. At this time, the second movable plate 151 will start to move. During the movement, the second movable plate 151 will be connected with the push plate 20 on one side. Under the continuous movement of the inner rotating rod 17, the first movable plate 151 and the corresponding push plate 20 will move forward.

Repeat the above operation to take out the condensed gas from the discharge port 5. During the operation, the gas in the second cavity will enter the third cavity through the corresponding partition block 9 again. The gas in the third cavity will be condensed for the third time. At this time, the temperature in the cavity reaches the condensation temperature of the methane gas. At this time, the condensed liquid has higher purity. After the condensation is completed, the liquid is discharged from the discharge end 4. Then, the above operation is repeated to condense.
[0032] When the methane gas purity of the condensed gas is high, all the condensers 2 can be adjusted to-160℃ or a small range of decreasing temperature, and then the gas can be directly input from the inlet 3. After a specified amount is input, control the second motor 7 to rotate to close the partition block 9.
