Description
The decanter centrifuge with the features of strong solid-liquid separation capacity, high efficiency and large treatment capacity, which has been widely used in sewage treatment, greatly reducing the cost of sewage treatment, and creating huge economic value and social environmental protection value.
The horizontal screw discharging and settling centrifuge (referred to as horizontal screw centrifuge) with a fully closed and continuous operation with a large length-diameter ratio is used as the main machine of the sewage treatment centrifuge, which has the following advantages:
1. Fully closed operation, clean and pollution-free site.
2. The amount of flocculant and cleaning water is small, and the daily operation cost is low.
3. The equipment layout is compact, covers a small area, can significantly reduce the land acquisition and infrastructure investment.
Working principle :
In a sewage plant, what is the process of using a spiral settling centrifuge for desliming?
In sewage treatment plant, in the treatment of activated sludge, the whole process of using spiral settling centrifuge is: through the high-speed rotating drum, to drive the high-speed rotation of sludge, and then generate centrifugal force, so that the solid particles in the sludge settlement is accelerated, and concentrated on the drum wall. Then, through the spiral, the mud cake is scraped to the small end of the drum, so that it can be discharged, thus completing the mud removal work.

Problems would occured and solutions:
1.The decanter centrifuge seems not that good - it is very important to choose the suitable model:
The decanter centrifuge looks similar, and the principle is to accelerate the sedimentation of solid and liquid by applying centrifugal force field according to the specific gravity difference of solid and liquid to achieve the purpose of separation.
But the different emphasis in the design brings the different applications. Differences in the parameters of the fuselage components, such as the processing capacity, slag removal capacity, drum requirements and other structural design, which makes the horizontal screw centrifuge more suitable for the process requirements.
Since it is sewage treatment, it can achieve twice the result with half the effort only by purchasing the centrifuge equipment suitable for the sewage treatment process
2. The separation effect of decanter centrifuge is unstable - parameter adjustment is very important:
Although the parameter setting habits of different manufacturers are different, in general, in order to better respond to material changes and enhance the general performance of the machine, the commonly used required parameter adjustment includes drum speed adjustment, speed difference adjustment of the push differential, overflow plate height and other settings. It is hard to imagine how the parameters of engineering mud desliming can be used to treat steel plant wastewater directly.
3. The separation effect of decanter centrifuge is not good - pretreatment is very important
For solid-liquid separation of decanter centrifuge, it is inevitable that particles with extremely fine particle size are still suspended in the liquid phase. For different processing objects, a reasonable process specification (sop) should be formulated, and the process specification operation should be strictly implemented. For the addition of precipitant, flocculant and other chemicals, it should be strictly implemented, so as to prepare for the next solid-liquid separation stage of decanter centrifuge to achieve the best separation effect
FAQ :
Q:The paper mill sewage is treated with a horizontal screw centrifuge. It is found that there is a little bit more slag and blockage. How to deal with it?
A:How to judge that the horizontal spiral centrifuge has a little more slag? Is it compared with the same technical parameters before? Or did you change another decanter centrifuge or add too much medicine? Increasing the precision of machine parameters or the dosage of reagents both can bring about more slag discharging. In short, the smaller suspended solids that were previously hidden in the sewage are also separated by centrifugation. If the pretreatment is not done well, it can also increase the solid content of the fluid.
We have 2 solutions to solve the condition of more slag. One is to do a good job of pretreatment to reduce the solid content of the fluid, and the other is to adjust the differential speed of the spiral sweeping paddle of the horizontal screw centrifuge to make the pushing more smooth. We use the juneng horizontal spiral centrifuge, which is very stable in performance. After more than two years of use, there is no sudden change in performance.
