In the process of using the decanter centrifuge, the problem of slow dehydration power of the centrifuge is encountered. The specific performance is as follows: with the increase of the solid image material in the drum, The dehydration of the centrifuge is prolonged, and the situation is not taken off. This phenomenon is a common phenomenon.

In order to improve the dehydration power of the decanter centrifuge, it is possible to increase the rotation speed of the centrifuge drum within the safety assurance range and without corrosion or corrosiveness of the material; The filter area inside the drum. The specific implementation method is to increase the lining net, to keep small gaps between the filter bag and the decanter centrifuge drum, to improve the water permeability; and to increase the cross-sectional area, such as adding a V-shaped filter baffle. Of course, a small number of repeated dehydration methods, reducing the amount of dewatering and filtering materials in each centrifuge, and more, less material discharge method can also improve the power of the decanter centrifuge.

If the material is sticky, wash it within the scope of the process. To increase the size of the solid phase material particles, if the process is constant, if you want to increase the rate of concern, you can consider adding, such as flocculating agents. During the operation of the horizontal screw centrifuge, the parameters such as the rotational speed of the drum, the dry solid load, the type of flocculant, the manufacturing concentration of the flocculant, the dosage and the orientation, the thickness of the liquid ring layer, and the speed difference curve are modified. The solid content of the dewatered cake and the solid content of the supernatant make the centrifuge operate in a good condition.

We found through actual operation that among the above-mentioned many factors, the setting of the thickness of the liquid ring layer and the adjustment of the speed difference are crucial to the effect of sludge dewatering.

Tips: Maintenance of the centrifuge:

1. Clean the centrifuge chamber and return it, and dry the condensate in the chamber.

2. Open the door after use until the chamber returns to normal temperature.

3. Balance the sample before centrifugation.

4. After centrifugation, pay attention to disinfection and sterilization.

5. Pre-cool the rotor if necessary, return to the protection and storage, pay attention to the bottom of the counting ring.
