SECONDARY VORTEX TYPE SEPARATOR

PROBLEM TO BE SOLVED: To provide a cyclone type separator which is reduced in resistance of the passage and separates efficiently even minute target substances so far being difficult for conventional techniques to separate.SOLUTION: In the cyclone type separator, a secondary vortex cylinder having an opening at the first end and a pivot not overlapping the extension of the pivot of the main vortex flow is arranged in a plane in contact with the vortex flow in the main passage for a carrying fluid, and a collection chamber having no opened parts other than an opening at the second end of the secondary vortex cylinder is disposed. A target substance in the carrying fluid is separated by means of a secondary vortex flow which is generated by the vortex flow in the main passage, has a small diameter and circles at high speeds.
