Horizontal and high efficiency Cyclone Separators carbon steel dust collection circulating fluidized bed technology
Product Description
| • | Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. |
| • | When removing particulate matter from liquids, a hydrocyclone is used; while from gas, a gas cyclone is used. |
| • | Rotational effects and gravity are used to separate mixtures of solids and fluids. |
| • | The method can also be used to separate fine droplets of liquid from a gaseous stream. |
Operating Principles
| • | Although there are four commonly used cyclone separators, their operating principles based on that of the conventional cyclone, are very similar. |
| • | In the conventional cyclone, the gas enters a cylinder tangentially, where it spins in a vortex as it proceeds down the cylinder. |
| • | A cone section causes the vortex diameter to decrease until the gas reverses on it and spins up the center to the outlet pipe or vortex finder. |
| • | A cone causes flow reversal to occur sooner and makes the cyclone more compact Dust particles are centrifuged toward the wall and collected by inertial impingement. |
| • | The collected dust flows down in the gas boundary layer to the cone apex where it is discharged through an air lock or into a dust hopper serving one or more parallel cyclones . |
| • | Although conventional cyclones can be built to larger diameter, they are commonly 600 to 1600 mm in diameter. |
Parameters
| • | The most important parameters of a cyclone as for any separating device are its collecting efficiency and the pressure drop across the unit. |
| • | The collecting efficiency of a cyclone is defined as its ability to capture and retain dust particles whereas the pressure drop is the amount of power that the unit needs to do so. |

Advantages
| • | The collected product remains dry and, normally useful. |
| • | Low capital investment and maintenance costs in most applications. |
| • | Very compact in most applications. |
| • | Can be used under extreme processing conditions, in particular at high temperatures and pressures and with chemically aggressive feeds. |
| • | No moving parts. |
| • | Can be constructed from most any material suitable for the intended service including plate steel, casting metals, alloys, aluminum, plastics, ceramics, etc. |
| • | Can be equipped with erosion or corrosion resistant or ‘particle repelling type liners. |
| • | Can be fabricated from plate metal or, in the case of smaller units, cast in molds. |
| • | Can, in some processes, handle sticky or tacky solids with proper liquid irrigation. |
| • | Can separate either solids or liquid particulates; sometimes both in combination with proper design. |
