Title:
METHOD AND DEVICE FOR PROCESSING THE DRILLING MUD
Document Type and Number:
WIPO Patent Application WO/1980/002046
Kind Code:
A1
Abstract:
When processing the drilling mud by passing it through the electrical field of the negative electrode of an electrolyzer the tension on the electrodes is increased until the start of electrophoresis leading to sedimentation of particles of the solid phase on the surface of the positive electrode until a crust is formed on it and, after the creation of the crust, the tension on the electrodes is further increased until the start of a regime of electrochemical decomposition of the drilling mud, the tension being maintained at such a level that the crust is conserved, at least partially, during the whole process of treatment. The device for implementing the method comprises a reservoir (1) with negative and positive electrodes (3) and (4) therein. The negative electrode is designed as a pair of hingedly interconnected plates (5) and (6) oriented at an angle to each other and across the drilling mud flow. The positive electrode (4) is of a laminated construction and is fixed in front of the hinged joint at the lower lewel of the drilling mud flow.
