Introduction of Decanter Centrifuge’s Differential Speed

The differential speed of the screw and bowl in the Decanter centrifuge directly affects the slag discharge capacity, the degree of muddy dryness, and the quality of the filtrate. It is one of the important parameters in the decanter centrifuge that needs to be adjusted according to the operating situation.

Increasing the differential speed is conducive to improving the Decanter centrifuge‘s slag discharge capacity, but the dewatering time of the sediment will be shortened, and the moisture content of the mud cake will be large after dehydration.

Decreasing the differential speed will increase the thickness of the sediment, the sediment dewatering time will increase, and the moisture content of the mud cake will decrease after dehydration. At the same time, the spiral will have less disturbance to the material in the clarification zone, and the quality of the filtrate will be relatively better. To prevent the slag discharge from reducing the material blocking phenomenon caused by the sediment in the centrifuge can not be discharged in a timely manner, to prevent a large amount of mud in the filtrate, then you must reduce the amount of feed or increase the differential speed.

Some types of equipment have the function of speeding up slag discharge automatically. After the set torque reaches a certain limit value, the equipment will automatically reduce the amount of mud and medicine, increase the differential speed, and quickly push out the accumulated mud ring layer. After the torque is reduced to a certain value, the flow and difference Degrees automatically return to normal. This is a measure to effectively protect the equipment. However, in the long-term operation, this situation should be avoided frequently, because it is easy to make the decanter centrifuge often in an condition of unstable flow and unstable differential speed. The fluctuations in the process will affect the processing effect and reduce the processing capacity.

Therefore, the differential speed should be determined according to the nature of the material, the amount of processing capacity, the processing requirements and the structural parameters of the decanter centrifuge. To put it simply: there is a contradiction between the processing capacity and the processing effect. To increase the processing capacity of the decanter centrifuge, it is necessary to increase the differential speed ratio, but the degree of muddy biscuits may be reduced. Capacity, so the on-site debugging work is to find the best equipment operating conditions parameters that meet the actual sludge properties of the respective site, in order to achieve the dual purpose of the highest equipment operating efficiency and the best treatment effect. There is no simple data to calculate, only rely on long-term actual debugging to accumulate experience, and adjust in time according to changes.

At the same time, within a certain range, the control of the degree of speed difference and the control of the amount of flocculant dosing complement each other. When a certain degree of muddy dryness is required, if the degree of difference is reduced, the amount of flocculant dosing can be saved. To put it simply, increasing the pressure of equipment treatment will reduce the pressure of using flocculant. Therefore, the proper use of the lowest possible difference can reduce the consumption of flocculant to a certain extent. As the saying goes, “If the equipment works well, the medicine is saved, and if the equipment is not well operated, the medicine is spent.” It depends on the design and processing accuracy of the equipment itself, and it also involves the control of the operating parameters of the equipment.

For decanter centrifuges with automatic adjustment of differential degrees, the parameter settings of differential degrees should be determined in combination with long-term use, and amended in time according to various changes that may occur.

Decanter centrifuge used for the sewage treatment

Clean water is becoming more and more valuable raw materials, which is why the importance of urban sewage treatment continues to grow. The sludge from drinking water and sewage treatment must be separated as effectively as possible. At present, the industrial decanter centrifuge is considered as the latest technology of sludge dewatering and thickening, which has the characteristics of economy, energy saving and high efficiency.

GN company has more than 12 years of experience in sewage sludge treatment. We understand the special requirements of sewage treatment plant and water industry. The GN Brand has been in the industry since 2007. GN products have been exported to over 70 countries in the world. Over 70% of the products are made for international customers. GN have branch in Houston, USA and Moscow, Russia for support to our local customer. GN make different types of decanter centrifuge include Clarifying Centrifuge, Classifying Centrifuge, Thickening Centrifuge, Dewatering Centrifuge.

Sludge decanter centrifuge specially developed for the special requirements of sewage treatment plant

The main purpose of dewatering process is to minimize the volume of sludge. The reason is that every tenth increase of dry solid in sludge will reduce the cost of sludge removal. A higher dry solid content was obtained.

It not only eases the subsequent treatment process, but also improves the overall performance of the sewage treatment plant. GN company is used to compact the sludge, so that the dry solid content of the sludge is concentrated in a few percentage points.

GN decanter centrifuge can also be used for the best mud thickening of polymer based strong flocking agent. The polymer is largely removable, and the horizontal decanter centrifuge can achieve very good value.

The sewage sludge can be produced in drinking water treatment. The decanter centrifuge is used to reduce the transportation and landfill cost of sludge, increase the dry solid content, and reduce the amount of polymer required.
