[0007] Beneficial effects of the utility model:

[0008] The utility model adopts a three-layer filtering structure, which can effectively improve the filtering efficiency of methanol. It is convenient to maintain and replace filter tube three, filter tube two and filter tube one, and ensure the quality of output methanol. When the filter tube needs to be cleaned or replaced, it is only necessary to rotate the connecting seat to unscrew it from the outer cylinder, and then unscrew each filter tube separately.
