Crossflow filtration particle separator

An apparatus for separating particles from a fluid, the apparatus comprising:

• a housing having a closed distal end, with a proximal end configured for receiving a first flow of fluid containing particles to be separated and a second flow of fluid surrounding said first flow;
• a plurality of adjacent slits and baffles that are positioned diagonally along the sides of the housing located from center of said housing to its distal end;
• and
• a particle collector positioned at a bottom of said housing having a fluid connection through which particles are collected and taken away in a third flow having a flow rate which is less than either said first flow or said second flow;
• wherein said second flow shields particles from said first flow from exiting said slits;
• and
• wherein particles collect from the first flow at said particle collector in response to vortices created by a combination of fluid flow striking the baffles and passing through said diagonal slits, and fluid motion on the closed distal end.

An apparatus for separating particles from a fluid, comprising:

• a tubular structure with a closed distal end;
• said tubular structure forms a cavity and is configured for receiving fluid flow at a proximal end;
• a plurality of lateral baffles and slits positioned diagonally along walls of said tubular structure, with said slits having a width exceeding the particle diameter;
• and
• a particle collector disposed at the bottom of said tubular structure;
• wherein said fluid flow comprises a first fluid flow containing particles and a second fluid flow which annularly surrounds said first fluid flow;
• wherein a particle-free or low-particle concentration filtrate of said first fluid flow and second fluid flow exits the tubular structure through said lateral slits;
• and
• wherein the particles from said first fluid flow are concentrated at the particle collector in response to vortices generated in response to fluid flow interacting with the baffles, slits and closed distal end.
