Vortex separators - cyclones

Dry CLE cyclone separators are designed for coarse separation of solid particulate matter from materials mixed with air and exhaust. These are designed for suction HVAC systems. A mechanical process is used to separate this particulate matter via the use of a separation force. Such a force operates on the gases moving through the cylinder chamber of the cyclone. In this section it begins to rotate and comes into contact with the wall of the cyclone. Separation from the flowing gases occurs on the walls of the cyclone. The separated matter falls into the hopper for the cyclone and is then removed using a rotating feeder. The dimensions of the removed matter depend in the pressure gradient of the cyclone. The size of the separated particles will be proportionate for various sizes of cyclones at the same pressure gradient. In terms of energy efficiency sometimes it is suitable to connect a number of smaller cyclones in parallel instead of a single large cyclone. Such a connection is known as a battery of cyclones or a multi-cyclone. Cyclones can be connected in series in order to increase the efficiency of separation; this is known as multi-stage scrubbing. As a rule a smaller number of larger cyclones are connected to the first level and a larger number of smaller cyclones are attached to the second level; in some cases the same size cyclones can be applied in both levels.
One benefit of a cyclone is that it has not moving parts. Cyclones operate reliably at temperatures up to 500°C and at high pressures. Depending on their structure they can be used to separate abrasive materials as well. Separation is slightly dependent on the concentration of the material. Cyclones feature simple construction and production.
A drawback of a cyclone is the abrasion caused by separating materials that can lead to pitting in the cyclone. Due to this the cyclone must be constructed from suitable materials with sufficient sheet thickness pursuant to the characteristics of the separated material. Another drawback can be that cyclones are not suitable for separating adhesive materials.

Main components of a Cyclone separator:

1. Cyclone body - separation chamber
2. Cyclone hopper
3. Cyclone hopper neck
4. Cyclone inlet - primary section
5. Cyclone outlet
