Whole-Process Management and Intelligent Monitoring System for VOCs Emissions in Rubber Paste Preparation Workshops: Design, Implementation, and Field Validation

• • The hybrid database (MySQL + InfluxDB) reduced storage costs while enabling efficient time-series data handling, critical for long-term monitoring of VOCs emissions and equipment performance. • • Under typical conditions, extraction and ventilation flow rates of 40,000 m³/h and 30,000 m³/h, respectively, created a micro-negative pressure environment that suppressed fugitive emissions, ensuring compliance with GB 27632—2011. • • The purification process (zeolite rotor adsorption + regenerative thermal catalytic oxidation) consistently reduced non-methane hydrocarbon (NMHC) concentrations to below 10 mg/m³, meeting regulatory limits. • • Role-based access control and microservice architecture reduced abnormal response times and enabled precise operational responsibility allocation, improving system reliability and maintenance efficiency.
