Abstract
The invention discloses a spiral pipe gas-liquid separation method. Specifically, firstly a gas-liquid mixed fluid is introduced into a separation mechanism, and is then led into a spiral pipe by a gas-liquid mixed inlet, centrifugal acceleration is generated in the spiral pipe, so that under the combined action of centrifugal force and gravity, liquid with large relative density gathers at the lower side outside the spiral pipe, and gas with small relative density gathers at the upper side inside the spiral pipe, most of the gathered gas flows out of the spiral pipe through a small hole disposed thereon, the gas enters a defogging mechanism on a through-hole by means of the inertia effect of centrifugal accelerating, the defogging mechanism eliminates the residual liquid drops in the gas to ensure the purify of gas in an air outlet. The liquid flowing out of the spiral pipe starts settlement under the shunting effect of a diverter, and in the settlement process, the liquid settles to the cylinder bottom because of gravity and is discharged by the liquid outlet.
