Abstract:
A method of separating a â€œparticle containingâ€  fluid flow into a first flow component containing particles essentially greater than a selected size and a second flow component containing particles essentially smaller than said selected size, comprising the steps of:directing said fluid flow through a multiplicity of slit nozzles, positioning the slit nozzles so that the fluid flow is directed into a multiplicity of gaps, said gaps located between the multiplicity of slit nozzles and (a) a multiplicity of receiving chambers and (b) a multiplicity of exhaust chambers, locating the multiplicity of receiving chambers in alignment with the multiplicity of slit nozzles, locating the multiplicity of exhaust chambers offset from the aligned slit nozzles and the receiving chambers, selecting the multiplicity of slit nozzles, the multiplicity of gaps, and the multiplicity of receiving chamber inlets such that the fluid flow will be separated into the first flow component containing particles essentially greater than said selected size, which is directed into said receiving chambers, and the second flow component containing particles essentially smaller than said selected size, which is directed into said exhaust chambers.
