Abstract

1416556 Electrostatic separation COMMISSARIAT A L'ENERGIE ATOMIQUE 18 Dec 1972 [31 Dec 1971] 58319/72 Heading B2J [Also in Division G1] An electrostatic precipitator comprises a chamber 2 provided with plate electrodes 4, 6 between which a direct potential V1 is applied; an inlet duct 10 which merges into the chamber 2 with a conical configuration 12 which, together with the provision of a honeycomb structure 24 and grids 22, ensures that gas flows smoothly without turbulence from the duct 10 into the chamber 2; and a conduit 16 provided with an ioniser 20 and an outlet 18. In use, polluted gas containing suspended particles which have been charged by the ioniser 20 is injected by way of the conduit 16 and an outlet 18 into a non-turbulent flow of "clean" gas supplied from the duct 10. The charge acquired by each particle is dependent upon its size, and as the flow through chamber 2 is non- turbulent, each particle is attracted to the collector plate 4 to a greater or lesser extent in accordance with its size. Thus larger particles are collected on the plate 4 during the earlier part of the passage of the polluted gas through the chamber 2 and smaller particles during the later part of the passage. Accordingly, particles graded as a function of their size can be collected on the plate 4 for later quantitative and qualitative analysis. A further electrostatic precipitator 28 may be provided to collect any particles, which will be uncharged, in the gas supplied through the duct 10. Thus, if the pollution of atmospheric air is to be investigated, this air is supplied both to the duct 10 and the conduit 16, the particles in the former being collected generally in the precipitator 28 and the particles in the latter, which have been charged by the ioniser 20, being collected as a function of their size in the chamber 2. A modified precipitator is described with refereence to Fig. 3 (not shown). The ioniser 20 is energised from both A.C and D.C sources, a suitable construction being described with reference to Fig. 2 (not shown).
