When the horizontal spiral centrifuge is in operation, its high-speed rotating drum will generate strong centrifugal force to throw solid particles with a density greater than the liquid phase on the inner wall of the drum to form a solid layer (because the ring is called solid Ring layer); due to the low density and low centrifugal force, the water can only form a liquid layer inside the fixed ring layer, called the liquid ring layer. Due to the different rotation speeds of the screw and the drum, there is relative movement between the two (that is, the difference in rotation speed). The relative movement of the screw and the drum is used to slowly push the sludge of the fixed ring layer to the cone end of the drum and pass through the drying area. Afterwards, it is continuously discharged from the outlets distributed on the circumference of the drum, and the liquid in the liquid ring layer is continuously \"overflow\" discharged from the weir mouth by gravity to the outside of the drum, forming a separation liquid.
Operation management of horizontal spiral centrifuge
Since the horizontal spiral centrifuge is a blast furnace gas washing water sludge treatment system, the recovered water quality changes greatly, the sludge particles are seriously worn on the equipment, and there are many uncertain factors affecting the outside world. In addition, the system has many types of treatment equipment and treatment. The links are interleaved, which has high requirements on the operating personnel. Therefore, to ensure the normal operation of each link and give full play to the role of the facilities and equipment, it is necessary to strengthen daily operation management and a set of management measures to ensure it.
The role of horizontal spiral centrifuge
The horizontal spiral centrifuge uses the principle of centrifugal sedimentation to separate the drilling suspension. The blade on the screw pusher is pushed to the slag discharge port of the small end of the drum and discharged, and the liquid phase overflows through the overflow hole of the big end of the drum. Such continuous circulation in order to achieve the purpose of continuous separation.
