  • Soil gas extraction apparatus
    Patent number: 9708789
    Abstract: A soil gas extracting apparatus is used to vent hazardous soil gases out of the ground and into the atmosphere. The soil gas extracting apparatus makes use of a compressed air nozzle, a compressed air source, a vacuum-inducing tubular chamber, and a gas-receiving line to safely remove soil gases from the ground. The compressed air source forces air through the compressed air nozzle in order to generate a vacuum within the vacuum-inducing tubular chamber as the air flows into the gas-receiving line. The vacuum draws soil gases into the vacuum-inducing tubular chamber in order for the soil gases to be mixed with the air within the gas-receiving line and vented into the atmosphere.
