Zusammenfassung: | Acid mist is extracted from electrolytic cells and conveyed to a first device for trapping electrolyte droplets and condensing the hazardous contaminating sulfuric add vapors, then gaseous discharges are collected in a manifold, and the first devices are either connected directly to a second multi-chamber device for condensing the acid waste vapors that have not been trapped, which is connected to a gas extractor system which exhausts said gas either directly to the atmosphere or to a chemical treatment system for purification prior to discharge; or alternatively, the manifold discharges directly to an extractor system, which in turn discharges either directly to a centralized waste gas and vapor removal system or to the atmosphere. The recovery and recycling system further comprises a system for collecting condensates for reuse in the process and two systems for the measurement, control and regulation of acid mist extraction flows. |
