High Efficiency Simple Structure Uniflow Cyclone with Tangential Inlet


Description of Technology

Researchers at the University of Calgary, in partnership with industry, have developed, tested and implemented a heated uniflow cyclone designed to more efficiently remove particulate matter from emissions or collect particulate material from a gas carrier.

Cyclonic separation is a method of removing particulates from air (or gas) using centrifugal forces. Rotational effects are used to separate mixtures of solids and gases. The performance (efficiency and energy cost) of cyclone separators is dependent upon the diameter of gas-borne particles and the pressure drop between the inlet and outlet of the cyclone.

This improved uniflow cyclone was designed and optimized for capacities of 600, 3000 and 10000 cubic meters per hour. It can operate at 90 – 95% efficiency, which is 10% more efficient than current models being developed and extract particulate less than 10 micrometers using standardized ISO samples. This design can be used in a horizontal, vertical, or inclined orientation and the new features make it simpler to build.
