- Jun 24, 2019-

The decanter centrifuge for sludge speparating is used to adjust the diameter of the big end overflow plate of the sludge separation drum, which can change the effective length of the drum settlement zone and the drying zone. When the diameter of the overflow plate is small, the settlement zone increases and the drying zone decreases. The depth of the drum pool increases, and the solid content in the liquid phase can be reduced after separation, but the moisture content of the solid phase sediment increases, and the diameter of the overflow plate increases, the length of the sedimentation zone decreases, the length of the drying zone increases, and the liquid phase after separation The solid content will increase, the separation effect will be worse, and the moisture content of the solid phase sediment will be reduced. In actual use, it should be considered according to the separation requirements. After the operation test, the appropriate diameter D of the overflow plate should be selected.

 

The differential speed of the sedimentation centrifuge for sludge separation is small, the spiral is less disturbing to the fluid, the separation effect is better, the residence time of the solid phase sediment in the drying zone is longer, the solid phase moisture content is reduced, but the solid phase slagging capacity is decreased. It is easy to produce blocking material; if the difference speed is large, the spiral will increase the disturbance of the fluid, the separation effect will be worse, the residence time of the solid phase sedimentation in the drum will decrease, and the moisture content of the solid phase sediment will increase, but the solid phase row will increase. The slag capacity is increased.

 

The determination of the differential speed of the sedimentation centrifuge for sludge separation is generally determined according to the solid content of the material. If the solid content is large, the differential speed should be selected. If the solid content is small, the smaller differential speed can be selected. The initial differential speed is determined according to the test, and is determined by factors such as separation requirements and processing capabilities. The initial differential speed adjustment can be realized by adjusting the frequency of the hydraulic inverter in the running state, and the initial differential speed is generally in the range of 5 to 15 r/min.
