The structure and principle of the degasser.

Degasser Principle

Degasser is used to remove gas from gas-invaded drilling fluid to ensure the relative stability of drilling fluid performance and the normal operation of cyclone. The degasser is divided into two main categories: Atmospheric and Vacuum.

Atmospheric degasser uses centrifuge to suck air into the mud, and uses centrifugal force to make the mud spray and impact the inner wall of the spray tank, so as to release the gas.

Vacuum degasser takes advantage of the suction action of vacuum pump to form negative pressure in vacuum tank. Drilling fluid enters hollow shaft through suction pipe under the action of atmospheric pressure. Then the umbrella sheet assembly around the hollow shaft is jetted to the wall of the tank. The gas escapes through the vacuum pump and draws side-by-side to the safety zone.
