As a common separation and classification equipment, the cyclone is a very important classification equipment in mining operations, and can also be used for concentration and dehydration. Its working principle is centrifugal sedimentation. When the two-phase mixture to be separated enters the cyclone tangentially from the periphery of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotating shear turbulence is generated. Due to the difference in particle size between coarse particles and fine particles, the centrifugal force, centripetal buoyancy, fluid drag force, etc. they receive are different. Due to centrifugal sedimentation, most of the coarse particles are discharged through the bottom outlet of the cyclone, while most of the fine The particles are discharged from the overflow pipe to achieve the purpose of separation and classification. If the hydrocyclone cannot be used reasonably in the mine, it will directly affect its work efficiency. Generally, the factors that affect the work efficiency of the hydrocyclone mainly include the following aspects.
Today we will work with the cyclone manufacturer to understand the factors that affect the separation failure of the cyclone, and hope to help you:
1. The influence of the diameter of the inlet oil droplets The diameter of the oil droplets dispersed in the inlet fluid is another decisive factor affecting the separation efficiency. According to their functions, cyclones are divided into grading cyclones, dehydration cyclones, desliming cyclones, deslagging cyclones, concentration cyclones, and special cyclones for dry tailings discharge.
2. Influencing factors of split flow When using cyclones for separation, the choice of split flow is very important. For different separation processes, you can choose a suitable split ratio according to your needs.
3. The inlet flow rate is an important factor affecting the separation efficiency of the cyclone. As the flow rate increases, the tangential flow velocity increases, and the centrifugal force also increases, which promotes the separation of oil and water. On the other hand, the increase in the flow rate causes the oil droplets to break, causing a drop in separation efficiency. The size of the flow determines the smoothness of the swirling flow inside the cyclone and the movement of the dispersed droplets.
9 factors that affect the efficiency of hydrocyclones:
1. The diameter of the cyclone
The diameter of a hydrocyclone is an important condition that affects its working efficiency. The larger the diameter of the hydrocyclone, the larger the production capacity and separation particle size.
2, the cone angle of the cyclone
The working efficiency of the hydrocyclone decreases with the increase of the cone angle of the hydrocyclone, because the larger the cone angle of the hydrocyclone, the greater the resistance, which affects its production capacity.
3, the diameter of the feed pipe of the cyclone
The diameter of the feed pipe of the hydrocyclone has a certain effect on its processing capacity and classification efficiency. Generally, the larger the diameter of the feed pipe, the greater the processing capacity.
4, overflow pipe diameter and wall thickness
When the inlet pressure of the hydrocyclone is constant, the diameter and wall thickness of the overflow pipe are proportional to its production capacity.
5. The shape and size of the inlet
The cut surface shape of the feed port of the general cyclone is mainly divided into two types: round and rectangular. The feed port can transform the linear motion of the liquid flow into circular motion at the entrance of the column section. Therefore, the shape and size of the feed inlet of the cyclone directly affect its production capacity and separation efficiency.
6, the diameter of the bottom orifice of the cyclone
The larger the diameter of the underflow orifice of the cyclone, the finer the grading particle size, but its production capacity increases as the diameter of the underflow orifice increases.
7. The inner surface roughness and assembly accuracy of the cyclone
Under normal circumstances, the inner surface roughness and assembly accuracy of hydrocyclones have little effect on their production capacity and separation efficiency.
8. The feed viscosity of the cyclone
It has been proved through practice that the production capacity of the hydrocyclone will increase due to the increase of the feed viscosity.
9. The ratio of the underflow port diameter to the overflow port diameter
The ratio of the diameter of the underflow port to the diameter of the overflow port is called the cone ratio. The cone ratio is an important parameter for cyclone design. In general, the larger the cone ratio of the hydrocyclone, the smaller the grading particle size.
