The normal operating parameters of the Decanter centrifuge include a maximum mud feed volume and a maximum inflow solid volume. When the actual mud feed volume exceeds the maximum value, the decanter centrifuge will lose the dynamic balance of the solid phase and the liquid phase, and the torque becomes too large . In severe cases, the Decanter centrifuge will be damaged, or the centrifuge will be overloaded and stop running. Therefore, during the operation, the amount of sludge and solids flowing into the decanter should be strictly controlled.
Select the appropriate feed flow method: first, adjust the feed flow to a smaller value (under frequency control, generally adjusted to 60%~70%), then start the Decanter centrifuge and work for a while, know that the solid phase is out The speed of the material is balanced. Then sample 500 mL at the entrance of the decanter centrifuge to determine the sedimentation ratio of the mud. It is normal if the precipitation amount is within 100~150 mL within 5 minutes. Otherwise, the bypass valve needs to be opened to reduce the feed concentration.
The water quality recovered by the sludge treatment system changes greatly, and the sludge particles will cause serious wear on the equipment. In addition, there are many uncertain factors that affect the outside world. In addition, there are many types of processing equipment in the system, and the processing links are interleaved. Therefore, to ensure the normal operation of each link and give full play to the role of facilities and equipment, it is necessary to strengthen daily operation management. Supervise the operation management personnel to do a good job in daily operations. Familiar with the function of each equipment, handle the nodes of each link, and strengthen the coordination between the processes.
As a leading manufacturer of separation equipment and conveying equipment, GN always pay high attention to the product quality and consider the long-term benefits for our users. We would also like to introduce GN as a professional manufacturer in decanter centrifuge field, GN pays a lot of attention in the selection of raw materials, high-quality centrifugal casting or forging stainless steel materials are used, and for wearing parts, hard alloy protection is used.
