Basic Knowledge Of Liquid-gas Separators

Working principle: Gas-infiltrated drilling fluid enters the separator through the inlet. After colliding with the impact plate, it scatters onto a series of internal baffles. The collision increases the exposed surface area, causing it to flow downwards and creating turbulence, thus separating the gas from the drilling fluid. The free gas is discharged through the gas outlet at the top of the tank. The length of the exhaust pipeline is determined and provided on-site and led to a safe location. The degassed drilling fluid flows into the circulation tank through a vibrating screen.

Installation and Maintenance:

Install the separator on the ground next to the circulating tank (near the vibrating screen), and secure it to the ground with steel wire ropes from the lifting lugs at the four corners of the upper part of the separator body. Install an ignition chamber and ignition device at the exhaust pipe outlet. Before each use, check the lower buffer baffles. If the wear exceeds 10mm, both baffles must be replaced simultaneously before use. After each use, drain the drilling fluid from the separator (especially in winter to prevent the tank from freezing and cracking or becoming clogged), and clean it thoroughly by opening the cleaning port or manhole.
