COMPACT EFFLUENTS CONCENTRATOR RUNNING ON WASTE HEAT Russian patent published in 2014 - IPC C02F1/04 C02F1/16 B01D1/14 B01D1/16 

FIELD: process engineering.

SUBSTANCE: invention relates to concentrators of fluids, particularly, to compact low-cost effluents concentrators to be connected to waste heat sources that can be used for concentration of fluid. Proposed concentrator comprises gas inlet pipe, gas discharge outlet and flow channel communicating gas inlet pipe and gas discharge outlet. Note here that flow channel comprises contracted section to increase has flow rate therein. Fluid inlet pipe injects fluid in gas flow upstream of contracted section so that gas-fluid mix is completely mixed in flow section to cause the fluid partial evaporation. Mist separator or gas flushing unit downstream of contracted section removes trapped fluid drops from gas flow to return collected fluid into fluid inlet pipe via circulation circuit. Fresh fluid fed for concentration is forced into circulation circuit at the rate sufficient for compensation for fluid evaporated in said flow section.

EFFECT: reliable concentrator, longer life, concentration of fluid that notably differ by their parameters.
