Slanted baffle mist eliminator

Abstract

An apparatus for the elimination of mist from off-gas during vitrificationf nuclear waste, where baffles are installed on a slant toward the flow of the off-gasses eliminating the need to expand the cross-sectional area of the duct size.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
       1. An apparatus for the elimination of mist in off-gas during the vitrification of nuclear waste materials comprising: a hollow tube having an inner and outer wall area;   a plurality of baffles having an inner surface, an outer surface, and a base end, disposed in said hollow tube at an angle at least 45° in the direction of said off-gas, and configured whereby when said off-gas pass said baffles said mist impinges on said inner surface of said baffles and with the assistance of gravity collects at said base of said baffles; and   means for collecting said impinged mist along the inner wall area of said hollow tube.   
     
     
       2. The apparatus as recited in claim 1, wherein said baffles is selected from the group consisting of ceramic, glass, metal, and plastic materials. 
     
     
       3. The apparatus as recited in claim 2, wherein said means for collecting said mist consists of an orifice located at the base end of said baffles and said inner wall of said hollow tube, whereby a collection box is attached to the outer wall area of said hollow tube allowing said impinged mist to drain through said orifice and collect in said collection box until said impinged mist can be drained. 
     
     
       4. The apparatus as recited in claim 2, wherein said means for collecting said impinged mist consists of a slot cut into said baffles located at the base end of said baffles, and a drain cut into the inner wall area of said hollow tube, whereby said impinged mist collects at said base of said baffles and the frictional force of said off-gas push said impinged mist through said slot and out said drain. 
     
     
       5. The apparatus as recited in claim 4, wherein said means for collecting said impinged mist further comprises a channel in said inner wall area which directs said impinged mist to said drain. 
     
     
       6. The apparatus as recited in claim 5, wherein said baffles have an inverted u-shape. 
     
     
       7. The apparatus as recited in claim 3, wherein said baffles have an inverted u-shape. 
     
     
       8. The apparatus as recited in claim 5, wherein said baffles have an inverted v-shape. 
     
     
       9. The apparatus as recited in claim 3, wherein said baffles have an inverted v-shape. 
     
     
       10. The apparatus as recited in claim 1, wherein said tube is selected from the group consisting of ceramic, glass, metal, and plastic materials. 
     
     
       11. The apparatus as recited in claim 9, wherein said orifice is shaped corresponding to said baffles, thereby impeding the build-up of suspended solids from clogging said orifice.
