How is the model of a two phase decanter centrifuge determined?

The two phase decanter centrifuge is mainly responsible for the separation of solid and liquid. For different functions, the choice of models is also different. For example, when the solid phase concentration is high and the solid particles are rigid or crystalline and the particle size is large, a two-phase decanter centrifugal filter is selected.

 

If the granules are allowed to be crushed, a full-automatic two phase decanter centrifuge can be used. If the granules are not allowed to be crushed, a piston pushing or centrifugal force unloading centrifuge can be used. Besides, the dewatering performance is in addition to the water absorption performance of the material itself. In addition, it is also related to the separation factors, separation time, pore size, porosity, and other parameters of the two-phase decanter centrifuge, as well as the full-automatic centrifuge material, solution pH, particle characteristics, and process requirements.

 

In addition, in the case of a low solid phase concentration, a very fine particle size, or an amorphous mycelium, if a two-phase decanter centrifugal filter is used, the strainer runs severely due to the fine particle size. If the filter is too fine, the dewatering performance will be reduced. The amorphous mycelia and solid particles containing oil will block the filter. In this case, it is recommended to use screw decanter without filter, and choose the appropriate separation factor, length-diameter ratio, flow rate, slip and overflow radius according to the solid-liquid particle size and liquid-solid density difference.

 

In the process of choosing the two-phase decanter type centrifuge, if the density difference of the solid-liquid two-phase in the suspension is close and the particle size is more than 0.05mm, a two-phase decanter centrifuge can be selected. The former is through the filter medium - the filter, so that the solid-liquid separation of low energy consumption, high dehydration rate.

 

The latter is the use of solid-liquid density difference in the separation, in general, the energy consumption is higher than the filter automatic centrifuge, the dehydration rate is lower than the filter automatic centrifuge. The choice of these models is also related to the size of the treatment. Considering the large amount of treatment, continuous two-phase decanter centrifuges should be considered.

 

Under the premise of matching the appropriate two phase decanter centrifuge, the solid-liquid two-phase in the suspension can be completely and effectively separated, and the efficiency and precision of separation can be improved to meet the requirements for further application of the solution.
