Title: Improved method and apparatus for the recovery of suspended materials from gases
Inventor: RICHARDSON HARRY LEE
IPC: B01D50/00
Filed: 1952-10-27
Abstract: A method for the recovery of water-soluble materials suspended in hot gases comprises subjecting the gases successively to partial humidification, dry separation of suspended materials and wet separation of suspended materials with the aid of an aqueous washing liquid, and reintroducing aqueous liquid from the wet separation to effect at least part of the partial humidification of the hot gases. The dry and wet <PICT:0719757/III/1> separations are preferably carried out by dry and wet electrical precipitators.  In applying the process to the recovery of water-soluble cyanides from the gases from a ferro-manganese blast furnace, the hot gases from the furnace 10 are partially humidified by water sprays in a tower 13 and pass to a dry electrical precipitator 14.  The gases are then split into two streams one of which passes by a conduit 17 to be burned, e.g. under steam boilers, and the other is further purified by treatment in a gas washer 15 and finally in a wet electrical precipitator 16.  The electrodes of the precipitator are flushed with water and the resulting liquid is circulated by a pump 18 to the gas washer 15, thence by another pump 19 partly to the tower 13 and partly to the top of the blast furnace, where the liquid so introduced is evaporated into the hot gases leaving the furnace so that the cyanides which were dissolved in the liquid evaporated can be recovered in dry form in a dry dust catcher 12.
