Abstract
A separator comprises a separation chamber (1) with at least one inlet (11a) in its upper part, a solids outlet (12) in its lower part and two outlet pipes (2 and 3) for fractions of gas. Also described is a method which the separator uses, with the fractions of gas being sucked out in two separation zones generated inside the chamber, one with reverse flow and the other with unidirectional flow.
Claims18
A cyclone separator for separating particles from a mixture of gas and particles, said cyclone separator comprising:
- a separation chamber in which the particles are separated from the gas;
- an inlet configured to provide the mixture of particles and gas to the separation chamber;
- a reverse flow gas outlet positioned to receive a portion of the gas, from which particles have been separated, from the separation chamber, the direction of this portion of the gas having been reversed in the separation chamber;
- and
- a unidirectional flow gas outlet positioned to receive another portion of the gas, from which particles have been separated, from the separation chamber, the direction of this portion of the gas not having been reversed in the separation chamber.
A method of separating particles from a mixture of gas and particles, said method comprising:
- providing the mixture to a separation chamber;
- reversing the flow direction of a portion of the gas;
- allowing another portion of the gas to continue without reversing its flow direction;
- removing the portion of gas whose direction has not been reversed via a unidirectional flow gas outlet;
- and
- removing the portion of gas whose direction has been reversed via a reverse flow gas outlet.
