Solids control is a collective name, it includes five stage purification equipment, we can choose different products according to our different needs. Today, we will talk about drilling mud cleaner. It plays an important role in solids control system.
Firstly we talk about its structure, it is consist of manifold, shaker screen, and hydrocyclone. Hydrocyclone is composed of an upper cover, the upper cone, cone through the flange, clamps are connected as a whole and the bottom is a flower cap type low flow sand outlet. The cyclone overflow pipe and the liquid inlet pipe, a liquid outlet pipe is communicated through clamping band. Underflow is adjustable, can be properly adjusted according to drilling fluid containing sand content.
But how dose it work? Firstly drilling fluids are sucked up to 0.25Mpa ~ 0.4Mpa by sand pump, and enter into the cones through the side inlet which is normally only 2-1/2″diameter. The fluids then flow spirally inside of the cone. Effected by the centrifugal force, the heavy solids in the fluids would be thrown towards the inner wall of the cones, go down to the bottom, and discharge through the sand discharge port, while the light fluids would go up and discharge through the upper outlet. The diameter of the bottom discharge port is adjustable, and with a cover of hydrocyclone.
Mud cleaner is normally mounted after the vacuum degasser, but before centrifuge, so that the air that enter into the drilling mud can be first removed by degasser, and avoiding air blocking of the mud cleaner hydrocyclone. And the drilling mud with smaller particles can go to the centrifuge through vertical slurry pump to be further treated.
