Patent ID: 8025713

Claim:
An adjustable guide vortex gas-liquid separating apparatus comprising: a case; a gas throughflow pipe mounted in the center of the case; and a vortex flow guide spiral pipe mounted in the case around the gas throughflow pipe; wherein the vortex flow guide spiral pipe is connected with an inlet flange pipe section to allow an oil-gas-water multi-phase flow to enter into the vortex flow guide spiral pipe from the inlet flange pipe section; the vortex flow guide spiral pipe being configured to make the oil-gas-water multi-phase flow move in vortex to realize a gas-liquid separation, thereby forming a gas circuit and a liquid circuit; wherein the apparatus further comprises an adjusting valve mounted at an exit of the gas circuit, a measuring means for obtaining control information for the adjusting valve of the gas circuit, and a mist eliminator mounted inside a flange cover of the case; and a control information processing and transmitting system configured to control the opening of the adjusting valve based at least in part on the control information and thereby lower the gas content of the oil-gas-water multiphase flow to a certain range.
