| Abstract:This study established a comprehensive chlorine balance early warning and control system based on Six Sigma (6σ) management and intelligent IoT technology. By developing a dynamic equilibrium mathematical model for Cl⁻ involving six input sources (wood chips, mirabilite, NaOH, fresh water, recycled water, auxiliary materials) and five output categories (waste ash water, pulp, pulp residue, coarse residue, green mud, evaporation condensate), a blockchain-based material geographic information system (GIS) traceability platform was developed. Integrating multi-parameter intelligent early warning algorithms, a closed-loop management system featuring a four-in-one approach of “monitoring-assessment-early warning-regulation” was constructed. Industrial validation demonstrated that after implementation at a pulp and paper enterprise, Cl⁻ content in alkali ash from the recovery system stabilized at 20.1 g/kg (down from 22.3 g/kg), and waste ash water discharge from the alkali ash treatment system optimized from 9.40 m3/h to 8.55 m3/h, reducing alkali furnace ash accumulation. This minimized ash accumulation in the alkali furnace, maintained higher thermal efficiency, and decreased furnace cleaning frequency. |
