The compressed air introduced into the shell has impurities such as water vapor, oil stain and the like, and the air can be introduced into the air cylinder after the air and the liquid are separated. In this embodiment, two sets of systems for realizing compressed air cooling and gas-liquid separation are integrated into the same shell, specifically, cooling water in an outer cavity of the shell is used for cooling compressed air, a spiral flow guide pipe 5 in an inner cavity of the shell is used for performing gas-liquid separation on the cooled compressed air, the outer cavity for realizing compressed air cooling surrounds the outer side of the inner cavity for realizing compressed air gas-liquid separation, and the integral volume of the device is reduced while the compressed air cooler and the gas-liquid separator are integrated.

Then, the cooled compressed air enters the inner cavity through a connecting pipe 9 connected with a cooling coil 8, and the cooling capacity of cooling water in the outer cavity is transferred to the cavity wall of the inner cavity in the inner cavity to cool the compressed air again; simultaneously, the compressed air rotates under the diversion effect of the spiral diversion pipe 5 in the inner cavity, and the water vapor in the compressed air is cooled to form liquid under the secondary cooling effect of the cavity wall of the inner cavity, and the formed liquid is thrown onto the cavity wall of the inner cavity under the centrifugal force and flows downwards along the cavity wall of the inner cavity; and the resulting compressed gas is discharged upwardly from the top of the housing and flows into the cylinder.
The inner and outer chambers in the case in the present embodiment are independently provided by the partition plate 2 provided inside thereof.
In order to achieve the discharge of the resulting compressed gas, an outlet pipe 6 is arranged in the inner chamber, which is connected to the housing, the inlet of the outlet pipe 6 being in communication with the inner chamber, whereby the compressed gas enters the outlet pipe through the inlet and flows out of the housing.
