A device for conversion of carbon dioxide to oxygen, includes, in order, an axial compressor, a centrifuge compressor, a drum, an air pump, and a housing which provides an accommodating space to house the above assemblies together. The axial compressor and centrifuge compressor inhale the carbon dioxide rich air into the accommodating space, then the carbon dioxide rich air pass through the surface of the reactor drum which cause the carbon dioxide bouncing between the reactor drum and the wall of the accommodating space, the collisions of the carbon dioxide molecules will bend and break the molecule bond between carbon and oxygen to produce oxygen. The device, as mentioned earlier, provides a solution to the greenhouse effect, which eliminates the carbon dioxide and generates oxygen by physical method, and advances a design to enhance the conversion process, which has the potential of being enlargement.

A centrifugal separator for separating non-gaseous particles from a gas flow having a separator housing enclosing a rotor with a raw gas inlet, a clean gas outlet, and a particle outlet. A circumferential wall encloses the rotor. A raw gas flow is guided axially into the rotor. A clean gas flow is guided out of the rotor and then between the rotor and the circumferential wall to the clean gas outlet. The rotor comprises particle separation elements so that particles separated from the gas flow are centrifuged onto the circumferential wall. The circumferential wall particles are guided to the particle outlet via at least one particle guide trough running diagonal to the rotor axial direction on the interior of the circumferential wall. A radius of each trough as well as the distance between the rotor and the circumferential wall decreases in the direction of the clean gas flow.
