For example, when the drilling mud gas invasion occurs, usually the drilling fluid purified by drilling mud shale shaker goes into the grit tank of mud purification tank, then the suction of the vacuum pump causes negative pressure in the vacuum tank of vacuum degasser, which makes the mud come into the degasser for separation under the influence of atmospheric pressure.
The separated gas is exhausted and vented on the top of the mast, and the degassed mud is driven into the second compartment of mud purification tank by the rotor in the emptying the gas chambers.
When the mud in solids control equipment is at the aggravated state, the decanting centrifuges will not only remove harmful solid phase, but also the mud barite weighting material. It is very clear that this will result in lower mud weight quickly, increasing large loss of material. In order to avoid loss of the material and increase the purpose of removing harmful solid phase, we need to use two centrifuges in series, the middle speed centrifuge from the slurry tank for the pump proposed weighted mud after centrifuge, the mud after handling goes into the mud purification tank.

If the solids control equipment in the absence of gas in the mud, we can use the vacuum degasser as high power slurry agitator, keeping the slurry holding in the purification tank. The mud purified by shale shaker is exhausted and discharged to a dedicated tank at the bottom of middle speed centrifuge. A dedicated pump pumps it into the second stage of the high-speed centrifuge to separate again. After the separation, mud containing barite returns to the mud purification tank, maintaining slurry performance stable.
