Vertical reactor for dissolving gas in liq., and esp. oxygen@ in water - liquid and gas pass downwards through number of perforated plates at velocity chosen so that limited bubble zone is formed beneath each plate

摘要: In a procedure for dissolving gas in liquid, and especially oxygen (4) water (3), the liquid are introduced into upper part of long vertical reactor (2). Dispersion is assisted by one or more perforated plates (10), mixture withdrawn from lower reactor. The novel feature that velocity chosen so limited bubble zone (8) formed below each plate, no large bubbles remain this zone. Also claimed performing procedure, which has an outlet (13) with nozzles (12). USE/ADVANTAGE - For example enriching fish production, waste treatment industrial processes. A high rate achieved low pressure vessel.
