This utility model provides a high-precision gas-liquid separation and purification device, relating to the field of pharmaceutical production equipment technology. It includes: a tank body with a set of support legs at the bottom and an air inlet pipe on one side; a separator installed inside the tank body; a friction cover above the separator; and a wire mesh demister installed on the inner side of the positioning housing at a stepped groove.
