Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
172 words
A contaminant gas stream separator comprising a narrow unobstructed annular inlet orifice bounded on the outside by an axial downwardly and inwardly tapering frusto-conical housing and oN the inside by a coaxial outlet tube having an outer cylindrical division wall portion, a hood connected to the outer diameter of the frustoconical housing having an inlet in communication with said inlet orifice and an outlet in communication with said outlet tube, a coaxially located core being the frustrum of a right circular cone, the shape of the core and frustoconical housing projects an apex having a common point, the base of the core being located at the same level as the inlet orifice defining an annular outlet orifice with the division wall portion a conical cap superposed on the base of the frustrum extending into the tube to provide smooth velocity transition between the outlet orifice and clean gas discharge cylinder, a closed particulate matter storage hopper connected to the bottom of the frusto conical housing having means for removal of particulate material.
