Online Sodium Hypochlorite Production Monitoring

Blind Spot in Real-Time Monitoring of Key Concentrations: In sodium hypochlorite and sodium hydroxide production, there is a lack of real-time monitoring for effective chlorine and free alkali concentrations, resulting in insufficient production data support. Abnormal free alkali concentrations can affect the stability of subsequent reactions, while the effective chlorine concentration in sodium hypochlorite and the free alkali concentration in sodium hydroxide directly determine raw material quality. For instance, low effective chlorine levels can reduce the disinfection efficacy of sodium hypochlorite. However, traditional production methods lack real-time monitoring, relying on periodic sampling and data recording, which fails to capture sudden concentration fluctuations.

Delayed Regulation Disrupts Production Rhythm: Manual testing or delayed monitoring impacts the efficiency of production plan execution. Most companies rely on manual periodic testing, typically conducted once every two hours, with the process from sampling to results taking over 30 minutes. If test results indicate excessive concentrations, production adjustment instructions reach the workshop nearly an hour later, disrupting the planned batch production schedule.

Safety Risks from Manual Sampling: Production involving chemical substances poses safety hazards during manual operations. Sodium hypochlorite is corrosive, and sodium hydroxide is a strong alkali. Manual sampling requires contact with raw material solutions, and improper protective gear can lead to liquid splashes and burns. For example, a factory reported an incident where a worker's glove was damaged during sampling, resulting in sodium hydroxide solution contacting the skin and causing burns, which impacted both worker health and production efficiency.
