Cyclone separator design software

Sizing and selection of suitable inlet distributor for vertical and horizontal vessels. Liquid in gas droplet carryover calculator for horizontal and vertical vessels e. Design of fluidized-bed sand jet system and calculation of required headers and nozzles. Another way to think of this process, is to think of higher density particles colliding with the cyclone body whilst less denser particles are retained within the gas stream.

This is not strictly true though as both the density and shape of the particle will affect its ability to be separated from the gas stream.

Particles discharged through the reject port are usually either recycled off or on site , or, disposed of. It is a common misconception that centrifugal force is the force that separates the particles from the gas stream, but it is centripetal force that causes the particles to collide with the separator body.

The below equation is used to calculate the centripetal force based on the air velocity v , particle size m and radial distance r from the cyclone wall. Centripetal forces generated within the separator may be anywhere between five times gravity for large diameter low pressure drop separators, to 2, times gravity for very small diameter high pressure drop separators.

There are several factors that can affect a cyclone separators efficiency. We will now discuss the more important design aspects in greater detail. When the particle density decreases, the efficiency decreases assuming no other system changes occur. Larger particles can be more easily separated than smaller particles. Particles smaller than five microns are difficult to separate without using very small separators.

Particle exceeding microns can often be separated using other means such as gravity-settling chambers. A reduction in particle size will give a corresponding reduction in efficiency. A larger diameter cyclone separator will not be able to separate particles as efficiently as a smaller diameter separator.

The efficiency of the separator increases as the cone diameter decreases. Thus, reducing the cone diameter enables the removal of finer and finer particles.

A small diameter cone will extract much finer particles from a gas stream than a larger diameter cone. All cyclone separators have an associated pressure drop. The pressure drop can be thought of as the amount of energy required to move the gas through the separator, alternatively, it can be thought of as the amount of resistance the cyclone separator adds to the system flow.

The pressure drop is a product of the gas flow rate, gas density and cyclone geometry. Pressure drop can be expressed as:.

Click to adjust scale for selected variable. Click visibility icon next to StreamTracer1 to hide stream traces 2. Select Clip1 3. Adjust geometry Opacity to 0.

Note that this tutorial is meant only to demonstrate the capabilities of the software and not to solve the problem in the best possible way. Therefore, some assumptions are taken to keep case setup time and computational time low. In particular, to refine the model, one could in the first place consider refining the grid and choosing a more suitable drag model for the particles e.

Ergun-Wen-Yu model. Subsequently, it is worth considering enabling isotropic particle packing, isotropic particle time scale, and stochastic isotropy model. Cyclone Separator. After importing geometry, it will appear in the 3D window 1. Click Fit View to zoom out the geometry. Geometry was created in millimeters, we will scale it to meters 1.

Scale Geometry window will appear on the left side 1. After rescaling geometry, we should zoom in to see the geometry properly 1. Click Fit View to zoom in the geometry. Now we will set meshing parameters for cyclone geometry 1. Go to Hex Meshing panel 2. Enable meshing on the cyclone geometry. We will define the base mesh now 1. Go to Base tab 2. Define initial mesh extends Min [m] Define the number of divisions Division 25 20 To be able to define different conditions on each boundary of the domain we need to assign an individual name to each side of the base mesh 1, 2.

Make sure the material point is located inside the geometry 1. Go to Point tab 2. Make sure that the material point is set accordingly Material Point 0 0 0. Now everything is set up, we can begin the meshing process 1.

Go to Mesh tab 2. Click Mesh to start the meshing process. After meshing process is finished the mesh should appear in the 3D graphics window. We will now define properties of the discrete phase 1. Go to Discrete Phase panel 2. Set following parameters accordingly Total Mass [kg] 1. We will now define a normal distribution of the discrete phase size 1. Set distribution parameters accordingly Min [m] 4e Max [m] 3.
