COMPACT WASTEWATER CONCENTRATOR UTILIZING A LOW TEMPERATURE THERMAL ENERGY SOURCE

摘要

A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. A source of low energy gas, such as low pressure steam from a power plant, is connected to the liquid to be concentrated to heat the liquid to be concentrated before or during the concentration process.
