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.

Claims (109)

1. A soil gas extraction apparatus comprises:

a compressed air nozzle;

a compressed air source;

a vacuum-inducing tubular chamber;

the convergent-divergent nozzle comprises a fluid-converging portion and a fluid-diverging portion;

the convergent-divergent nozzle being integrated into the line inlet;

the fluid-converging portion being positioned adjacent to the compressed air nozzle; and

the fluid-diverging portion being positioned adjacent to the fluid-converging portion, opposite to the compressed air nozzle.

3. The soil gas extraction apparatus, as claimed in claim 1 , comprises:

at least one vacuum-extending units;

each of the at least one vacuum-extending units comprises a probe and a vacuum hose; and

the probe being in fluid communication with the vacuum-inducing tubular chamber through the vacuum hose.

4. The soil gas extraction apparatus, as claimed in claim 3 , comprises:
