When the horizontal screw centrifuge is operated, its high-speed rotating drum will generate strong centrifugal force to stick the solid phase particles with higher liquid density to the inner wall of the drum. On the top, a solid layer is formed (because of the ring shape, called a solid ring layer); since the water has a small density and a small centrifugal force, a liquid layer can be formed only inside the solid ring layer, which is called a liquid ring layer.

Because the rotation speed of the screw and the drum are different, there is relative motion between the two (ie, the difference in rotation speed), and the relative movement of the screw and the drum is used to slowly push the sludge of the solid layer to the drum. After the cone ends, and after passing through the drying zone, the outlets distributed by the circumference of the drum are successively discharged, and the liquid of the liquid ring layer is connected by gravity to the outside of the drum by gravity, and a separating liquid is formed.

I. Operation management of horizontal screw centrifuge

Horizontal screw centrifuge because the system is a blast furnace gas washing water sludge treatment system, the water quality of the recovery is large, sludge particles The equipment is seriously worn, and there are many uncertain factors in the external influence. In addition, the system has many kinds of processing equipments and the processing links are intertwined, which requires high requirements for the operators. Therefore, it is necessary to ensure the normal operation of each link and give full play to the facilities. The effect must be to strengthen daily operation management, and there must be a set of management measures to ensure.

Second, the effect of horizontal screw centrifuge

The horizontal screw centrifuge separates the drilling suspension using the principle of centrifugal sedimentation, and pushes it through the blade on the auger The small end of the drum discharges the slag port, and the liquid phase overflows through the overflow hole at the big end of the drum. This cycle continues to achieve the purpose of successive separations.

III. Liquid separation of horizontal screw centrifuge
