Gas washer Explanation: http://www.google.com/patents/US3444669 utra fine particles and water soluble substances "finely divided contaminant particles, so called ultra-fines. Such fines may be of an order of magnitude bordering on molecular sizes, e.g., in the range of one-half micron and smaller. Welding smoke, foundry and blast furnace stack gases, and gases around or used in pulverizing operations, e.g., pigment grinding, all are examples of sources of ultrafine particles. Chemical and refining operations also contribute polluting vapors and condensates in or approaching molecular sizes." |
