CIP Cleaning System for Electrolyte Container

Customer site photos:

Product highlights of the CIP cleaning system for electrolyte containers:

• Prevents HF formation – solvent pre-rinse removes LiPF₆ before water introduction

• Reduces solvent consumption by 40% – closed-loop recovery and distillation-ready discharge

• Achieves < 10 ppm residual lithium – verified by ion chromatography sampling

• Cuts cleaning cycle by half – parallel processing of up to three vessels via zone valves

• Extends equipment life – passivation step rebuilds chromium oxide layer on stainless steel

• Remote recipe management – upload new protocols via Ethernet/IP for different salt types

Core technologies of CIP cleaning system for electrolyte container:

The system operates on a five-stage principle: (1) solvent flush – DMC/EMC recirculation at ambient temperature to dissolve and carry away LiPF₆; (2) solvent recovery – vacuum distillation to reclaim >85% of cleaning fluid; (3) alkaline wash – 2% KOH at 60°C to remove organic carbonates; (4) acid rinse – 1% citric acid to neutralize remaining alkali and passivate metal surfaces; (5) nitrogen drying – heated gas at 80°C with dew point monitoring below -40°C. A conductivity meter controls chemical concentration, while a platinum RTD manages thermal ramps. The PLC logs all parameters for FDA/cGMP traceability.

Production line configuration for CIP cleaning system for electrolyte container:

• Solvent storage tank – 316L with PTFE lining, nitrogen blanket, level transmitter

• Solvent recovery still – electrically heated, condenses vapor into reclaimed solvent drum

• Alkali tank – jacketed, 100L capacity with agitator and conductivity probe

• Acid tank – similar construction, dedicated for citric or nitric acid

• Hot water tank – steam-heated, insulated, with automated fill valve

• Diaphragm pump set – air-operated, PTFE wetted parts, flow rate up to 30 L/min

• Spray ball manifold – rotating 360° heads for IBC totes and fixed nozzles for pipes

• Instrumentation – pressure transmitter, three RTDs, dual conductivity meters, dew point sensor

• Control panel – industrial PC with touch HMI, recipe storage for 5 container types, USB export

• Exhaust scrubber interface – connects to facility caustic scrubber for HF vapor capture
