Abstract
The present embodiments relate to a particle separation device. The particle separation device can include an inlet, a main channel comprising a series of angled portions to separate particles of varying sizes and varying flow rates. The particle separation device can also include a number of outlets to obtain particles of varying sizes. In some instances, the main channel can include multiple stages to allow for multi-stage sorting to increase sorting performance.
Claims40
A particle separation device comprising:
- an inlet for receiving particles of varying sizes and/or differing inertia across varying flow rates;
- a main channel comprising a first end and a second end, the first end connected to the inlet, the main channel comprising a series of angled portions, with each of the angled portions forming an angle of either less than or greater than 90 degrees to an adjacent angled portion, where the angle formed in the main channel is configured to provide an inertial separation of the particles received at the inlet;
- and
- one or more outlets connected to a second end of the main channel, each of the one or more outlets configured to receive separated particles of differing sizes and/or differing inertia.
1 more element
A particle separation device for separating particles of varying sizes and differing inertia across varying flow rates using inertial separation, the system comprising:
- an inlet;
- a main channel connected to the inlet at a first end of the main channel, the main channel comprising a series of angled portions, wherein each of the angled portions forming an angle that is greater than 90 degrees to an adjacent angled portion;
- and
- a set of outlets connected to a second end of the main channel.
1 more element
A particle separation device comprising:
- an inlet for receiving particles of varying sizes and differing inertia across varying flow rates;
- a main channel comprising a first stage and a second stage, with a first end of the first stage of the main channel connected to the inlet, the main channel comprising a series of angled portions, the main channel configured to provide an inertial separation of the particles received at the inlet;
- and
- at least two outlets, with at least a first outlet connected to the first stage of the main channel and a second outlet connected to the second stage of the main channel.
1 more element
A particle separation device comprising:
