Vacuum degasser use atmosphere and vacuum degassing theory eliminate the remaining gas in drilling fluid. Vacuum degasser tank is installed a group of wave blade and many mud inlet make flow is uniform distribution and form into turbulence in tank.

The throughput of vacuum degasser is 500g/m, 1200 type is 1200g/m, this is because the different area of wave blade. The blade area of vacuum degasser is 500 times of 500 type which is in order to ensure effective eliminate the remaining gas.

The vacuum tank produce low pressure in tank, the bubbles in the mud can well discharge. According the change of overload, vacuum pump proof motor can be adjusted. The mud liquid level in bottom tank feedback to a group of mechanical transmission device in order to automatic control inlet displacement and vacuum tank liquid level. Jet pump sucks out degassing mud from vacuum degasser tank.

Design characteristic

Drilling fluid enter into vacuum degasser from the inlet pipeline of tank wall. After gas is discharged from mud, flow to the bottom of vacuum tank. Degasser use vacuum and molecular collision / turbulence theory and maximize the surface area of drilling fluid to eliminate the gas.

Low pressure — the low pressure in vacuum tank make the bubble in mud is nature swell. It is more easy float to the surface of mud after bubbles is large and escaping mud.

Collision/ turbulence – the mud flow to the centre of tank and spray out from the ostioles which are in the wall of the tank. The liquid has enough force to impact the blade and tank wall. The result is the remaining gas is more easy escape to vacuum environment. The probability is big of blade is cracked.

Contacting area is maximum — in the process of mud splash to the tank from the odtioles in vertical pipe, the mud through a group of wave plate fine and thin blade make mud is disperse to increase the contacting area of the mud and vacuum environment. The residual gas is more easy to discharge.

Operation theory of vacuum degasser

Drilling fluid is transported to mud inlet from mud tank. Mud through degasser vacuum is bout 29inch of mercury is absorbed to vertical pipe. The mud splashes to wave blade and tank wall from the spray mouth of vertical pipe, the gas evolution this time and expose in the low pressure environment which is extracted by out tank vacuum pump.

The degassing mud ceaseless flow to bottom mud pit from blade group. Centrifugal pump is unceasing extract degassing mud by ejector.
