Gypsum hydrocyclone is the main separation area along the length of drum

Author: Time: June 6, 2020 132 views

Gypsum hydrocyclone is mainly used to separate mixed liquid through rotating grid, rotating drum and overflow nozzle. From the structure of dynamic cyclone separator, it has no chaotic tangential inlet, cylindrical section cyclone chamber, large conical section and long exhaust pipe as static cyclone separator. The main structural factors affecting the static cyclone separation function are the shape and quantity of tangential inlet, the main diameter and length of cyclone chamber, the structure and size of size cone and the main resolution of main diameter of cyclone chamber. The size of large cone section is mainly used for the pre acceleration of eddy current. The cross section of the small cone is mainly used for separation. The liner is mainly undulating from the core and has no separate function. Dynamic hydrocyclone is the main separation area along the length of drum. The structure and size of rotating grid, rotating drum, overflow nozzle and oil collecting sleeve are the main structural factors affecting its separation function.


The drum of gypsum hydrocyclone is the main occasion to cause liquid confusion. Dynamic hydrocyclone capacity separator is the friction force generated by high speed rotating drum, which is used to adjust the pre accelerated flow of rotating grid to form the required centrifugal force. Areas. Drums are high-speed moving parts. Parts, disassembly deviation and even material defects may lead to unbalanced centrifugal force during rotation



Among them, g-rotor assembly; e-deflection distance; w-rotor angular velocity; G-acceleration of gravity.

 Hydrocyclone

Even if the deflection distance of the drum is very small, the city will produce a large unbalanced centrifugal force, which is the main reason for the vibration of the machine or base. With the further increase of the rotating speed, the rotation speed of the drum is accelerated and the vibration is intensified. The rotation of the drum will cause the vibration of the cyclone separator, and the strong vibration will affect the flow field fluctuation in the cyclone separator.


The rotating raft is located at the inlet end of cyclone separator drum. If the friction between the inner wall of the drum and the liquid flow causes the liquid to rotate at a high speed, the eddy current force generated may not be satisfactory. In order to obtain sufficient tangent rate of rod solution. According to the requirements, the rotating grid of liquid that can be pre accelerated into the drum is configured. There are two main types of blades today. The taper should be planned at the end of the vane type rotating grid to make a kind of rotating liquid overflow the inner cavity of the rotary drum, so as to stabilize the flow transition and avoid strong eddy current. If the number of blades is too small, the flow field in the cylinder will be uneven; if the number of blades is too large, the flow area of liquid flow will be reduced, and the pressure loss and shear fracture energy level of droplets will be increased. Unfortunately, it's not obedient.


The overflow port of gypsum hydrocyclone is located at the end of cyclone separator. The main function is to collect light phase (e.g. kerosene) that has never been separated and extruded by rods. Water rings from the circumference of the rod. The cavity is crowded. In order to obtain better separation results, the structure of overflow nozzle is designed as a conical surface. This kind of gypsum hydrocyclone structure can reduce the inlet diameter and flow rate, and guide the steady flow of liquid flow, so as to avoid the formation of violent vortex and destroy the volatility of flow field.
