What kind of suspension does a horizontal decanter centrifuge apply to Jun 26, 2018

Horizontal decanter centrifuge is a kind of use of the solid-liquid specific gravity difference, and rely on the centrifugal force field to expand it several thousand times, the solid phase is settled under the action of centrifugal force, so as to achieve solid-liquid separation, and under the special mechanism Devices that are discharged from the body, respectively, are suitable for the separation of various mixed liquids.

 

The horizontal decanter centrifugal centrifuge uses centrifugation to separate the components of the suspension. The suspension added to the rotating drum forms a circular liquid layer under the action of centrifugal force. The solid particles settle to the wall of the drum to form sediment. The clarified liquid is discharged through a drum overflow or pipette.

 

For a difficult-to-separate suspension with a small difference in solid-liquid phase density, small solid particles, or large liquid viscosity, a horizontal decanter centrifuge with a high separation factor should be selected. Only when the suspension stays in the drum can the dispersion be maintained. clarify.

 

Horizontal decanter centrifuge has a wide range of applications, especially for centrifugal filtration, because the solid particles are easy to clog the filter medium and the filtration resistance is too large or the fine particle leakage is too large, the suspension separation can also be used for crystallization, chemical sedimentation, Separation of pulverized coal and other suspensions, dehydration of various sewage sludges, and deslagging clarification of animal and vegetable oils.

 

The horizontal decanter centrifugal centrifuge is divided into two types: intermittent operation and continuous operation. When the model of intermittent operation is separated, the sediment on the drum wall is gradually thickened, the effective volume of the drum is reduced, and the axial flow velocity of the liquid is increased, so that the separation liquid The increased number of solid particles removed can be used to treat suspensions having a solid particle size of 0.001 to 5 mm, a solid-liquid density difference of more than 0.05 kg/dm3, and a solid concentration of less than 10%.
