Both ends of the movable rod (753) pass through the adjustment frame (752) and extend to the outside of the adjustment frame (752).

8. A process for the distillation and purification of monofluoromethane, characterized in that: Step 1: The gas is transported to the purification cylinder (4) through the inlet pipe (6), while the water pump in the water storage cylinder (1) transports the liquid to the spray pipe frame (12) through the guide pipe (2). The liquid is sprayed by the spray pipe frame (12) to treat the gas. After spraying the gas, the liquid enters the drain pipe (10) for accumulation. Step 2: After being flushed by liquid, the gas flows upward through the movable space between the spray pipe frame (12) and the fixed block (11). As the gas enters the collection shell (82), it flows into the processing space formed by the assembly (852) and the guide cover (853). The flow of gas drives the rotating frame (855) to rotate on the assembly (852), and the filter disc (854) rotates together with the rotating frame (855). Step 3: The receiving plate (851) is distributed in a circle on the guide cover (853) and contacts the collection shell (82). The gas leaves the guide cover (853) and pushes the flip plate (84) so ​​that the flip plate (84) tilts down and contacts the swing plate (83), and drives the swing plate (83) to swing downward. As the gas flow decreases, the swing plate (83) pushes the flip plate (84) back to the initial position under the action of the elastic element at the swing position. Step 4: When the temperature control tube rack (13) is refrigerated inside the purification cylinder (4), the gas leaving the collection shell (82) is condensed and then transferred to the sealing sleeve (91). The gas is detected by the gas detection tube (953) inside the sealing sleeve (91). After the gas is qualified, it flows into the regulating sleeve (93). As the gas pushes the sealing plate inside the regulating sleeve (93), a gap is created and discharged through the discharge pipe (5). Step 5: When the temperature control tube rack (13) generates heat inside the purification cylinder (4), it dries the gas, thereby repeating the above flow steps. When the gas flows inside the sealing sleeve (91), the gas moving gas detection cylinder (953) is displaced, and the telescopic plate (952) extends and retracts with the gas detection cylinder (953), so that the overlapping plate (955) connected to the telescopic plate (952) slides on the middle solid frame (951). Step 6: As the liquid accumulates at the bottom of the purification cylinder (4) and enters the drain pipe (10), the adjusting frame (752) is pushed by the gas flow, causing the movable arm (751) to rotate on the fitting shell (71). The movable rod (753) drives the baffle (754) to slide on the adjusting frame (752) to contact the purification cylinder (4), and the contact rod (755) is distributed in a straight line on the baffle (754) to contact the purification cylinder (4) and rotate with the liquid. Step 7: The adjustment frame (752) is pulled by the rotation of the contact rod (755) via the spoiler (754). When the adjustment frame (752) and the movable arm (751) rotate, the push plate (73) slides and extends on the movable arm (751). As the push plate (73) extends and extends, it supports the movable arm (751). The movable arm (751) rotates and descends until it contacts the protective ring (72) and stops, so that the spoiler (754) pushes and guides the flow of liquid.
