Pulse-assisted multiphase extraction system and application thereof

The invention discloses a pulse-assisted multiphase extraction system and application thereof.The pulse-assisted multiphase extraction system comprises a plurality of extraction wells, extraction pipes arranged in the extraction wells, auxiliary agent injection equipment, multiphase separation equipment, water treatment equipment and waste gas treatment equipment, the extraction pipes are connected with a vacuum pump, and the auxiliary agent injection equipment is connected with the extraction pipes; intermittent pulse equipment is arranged in the extraction pipe and comprises an air pump, an air pumping pipe and an air bag, the air bag is arranged in the extraction well and wraps the air pumping pipe, and the air pump is connected with the air pumping pipe. The intermittent pulse equipment accelerates the removal of pollutants in soil and underground water, and avoids the phenomena of trailing and rebounding caused by a multi-phase extraction technology at the same time. Due to the pulse effect, a dominant c
