Design for Electrolyte Sedimentation Basin Based on COMSOL

The long spiral tube with its deep rifle groove make a long duration for Electrochemical Machining (ECM) and mass of floccule precipitate, esulting in bottleneck to maintain cleanliness of electrolyte in sedimentation basin at machining. The design scheme of duplex vertical flow electrolyte basin was proposed. The surface hydraulic power, available cubage, flooding area, sludge blanket level (SBH) and sludge tank height were calculated in terms of the electrical current, sinking speed of Fe(OH)3, flux of electrolyte. The streamline in the basin were simulated by COMSOL based elementary draft. The flow speed at intake of sludge blanket and the exit of clarified were analyzed with diameter of cone-meatus of center tube being altered and the space between it and baffle-board shifted, and the sedimentation basin is optimized.
