Title:

EXHAUST SYSTEM FOR DEEP WELL-TYPE GROUND ELECTRODE

Document Type and Number:

WIPO Patent Application WO/2021/036609

Kind Code:

A1

Abstract:

An exhaust system for a deep well-type ground electrode, comprising a first exhaust pipe (1), a second exhaust pipe (2), a U-shaped base (3), an isolation cloth (4) and filling particles (5), wherein the first exhaust pipe (1) and the second exhaust pipe (2) are fixed to the outside of a deep well-type ground electrode feed system extending underground; one end of the first exhaust pipe (1) located underground and one end of the second exhaust pipe (2) located underground are connected by means of the U-shaped base (3); exhaust holes are distributed on pipe walls of the first exhaust pipe (1) and the second exhaust pipe (2); the isolation cloth (4) is covered on the outside of the exhaust holes; and the filling particles (5) are filled between the exhaust pipes (1, 2) and a well wall. The exhaust system for the deep well-type ground electrode may effectively exhaust gas while preventing exhaust blockages caused by coke particles at the bottom part thereof, thereby improving the exhaust effect and prolonging the service life of the exhaust system.
