Abstract
A uniflow cyclone that has multiple inlets, normally achieved via a vane, a barrel length, then a solids collection channel of larger diameter but concentric with the barrel and a tangential solids outlet to either a plenum or a dust hopper. The gas flows past the enlarged channel and continues through additional barrel length to an outlet zone. The cyclone would normally have a concentric center pipe the extends from the vane to the gas outlet of the cyclone.
Claims8
A uniflow cyclone separator for removing solids from a vortex, the cyclone separator comprising:
- a first stage separator comprising:
- a barrel having first and second ends and comprised of a cylindrical wall having a predetermined height;
- a center pipe positioned within the barrel and extending for at least the entire height of the cylindrical wall;
- a gas inlet for injecting a fluid into the barrel proximate the first end;
- a vane attached to the center pipe proximate the gas inlet for initiating a vortex from the injected fluid;
- a peripheral channel positioned within the cylindrical wall proximate the second end of the barrel;
- and
- a tangential solids ejection port connecting the peripheral channel to a dust hopper;
- wherein,
- the vortex remains relatively undisturbed and continues through the barrel past the peripheral channel;
- and
- entrained solids within the vortex are removed by entering the dust hopper via the peripheral channel;
- a second stage separator stacked onto the first stage separator, the second stage separator comprising:
- an extension of the cylindrical wall from the second end to an extended end;
- an extension of the center pipe to extend the center pipe for at least the entire height of the cylindrical wall and the extension of the cylindrical wall;
- a second vane attached to the extension of the center pipe above the peripheral channel, the second vane being for maintaining the vortex of the injected fluid;
- a second peripheral channel positioned within the extension of the cylindrical wall proximate the second end of the barrel;
- and
- a second tangential solids ejection port connecting the second peripheral channel to a second dust hopper;
- wherein,
- the initiated and maintained vortex remains relatively undisturbed and continues through the barrel past the second peripheral channel;
- and
- entrained solids within the vortex are removed by entering the second dust hopper via the second peripheral channel.
