More Information
Summary:The invention discloses an improved multi-phase extraction system and method based on a light well-point dewatering technology. The extraction system comprises underground multi-phase extraction well groups and a ground jet-type vacuum system which is internally provided with a water supplement pipeline; and enough driving water in the ground jet-type vacuum system is maintained by controlling appropriate water supplement of the water supplement pipeline, so that the multi-phase extraction system stably operates. The ground jet-type vacuum system comprises a jet-type vacuum pump, a gas-water separator and a connecting pipeline, the connecting pipeline comprises the water supplement pipeline and is used for connecting the gas-water separator and the jet-type vacuum pump, and separated water automatically absorbed from the gas-water separator through vacuum suction force serves as the driving water of the jet-type vacuum pump. The invention further provides the extraction method of the extraction system. Accord
