The utility model provides a double-phase extraction soil and underground water remediation device suitable for in-production enterprises, and by adopting a mode of combining in-situ remediation and ex-situ remediation, soil and underground water can be remedied at the same time. A double-pump extraction system is adopted, a vacuum pump and a pneumatic diaphragm pump are arranged to extract gas and liquid in an underground polluted area respectively, the influence radius is large, the extraction rate can be freely adjusted, and limitation of the extraction depth of a single-pump system is avoided. A two-stage steam-water separator is adopted for ground surface equipment, extracted soil gas is primarily treated, it is guaranteed that gas entering the rear-end activated carbon box body is relatively dry, and the adsorption performance of activated carbon is not affected. The device can realize large-range remediation and treatment of deep polluted soil and underground water on the premise of not influencing surface production activities, and has the advantages of low carbon, environmental protection, small plot disturbance, low construction difficulty, adjustable remediation range and the like, and surface equipment is simple to operate and can stably run for a long time.

The utility model discloses a kind of gas buffer water slag separation semi-automatic two-stage blowout preventer, including separation tank, composite blowout preventer and buffer intake pipe, separation tank has the overflow port of water discharge and the exhaust port of gas discharge, composite blowout preventer imports the water, coal cinder and gas mixture discharged by drilling to separation tank, buffer intake pipe is connected with composite blowout preventer, valve one is installed on buffer intake pipe, valve one opens when two-stage blowout, high-pressure gas in blowout preventer is formed pressure relief, realizes two-stage blowout. Operating personnel carry out manual control pneumatic switch according to the safety requirement of gas content, when pneumatic switch opens, valve three on water slag discharge pipe, valve one on buffer intake pipe and dead lock closing device are synchronously closed or opened, quickly realize semi-automatic control gas discharge import and export, reach control gas concentration below safety value, reaction is timely, cost and technical dependency are lower.
