Regulation device for continuous neutralisation of an alkaline liquid medium by CO2, and application to the treatment of effluents

摘要

The present invention relates to a regulation device for continuous neutralisation of an alkaline liquid medium by CO2, comprising means for supplying with effluent and with gas containing CO2, characterised in that: - the means for supplying 1 with an alkaline liquid and with CO2 is of the suction type and sends the alkaline liquid and the CO2 in a mixed form into a constant volume degasser 2; - this means is associated with a double regulation system mounted on the degasser 2 comprising: - a loop comprising a pressure sensor 3, associated with a proportional regulation valve 4; - a drain trap 7. It is applicable in particular to the treatment of effluents. <IMAGE>
