Hebei Tangshan Desulfurization Hydrated Lime Conveying Project

Project Overview

This project addresses the conveying of desulfurization hydrated lime for a power generation facility in Hebei Tangshan. The system was designed to handle high-volume transfer of fine, reactive lime powder from storage to the injection point without environmental leakage or material degradation.

Customer Challenges

The client faced serious issues with their existing conveying method. Manual handling and mechanical bucket elevators caused frequent dust emissions, posing health risks to operators and violating local air quality regulations. The abrasive nature of hydrated lime led to rapid wear of mechanical components, resulting in unplanned downtime every two weeks. Additionally, inconsistent feed rates affected the desulfurization efficiency of the scrubber system, increasing operational costs.

Solution Provided

headpowder engineered a fully enclosed pneumatic conveying system specifically for dry hydrated lime. The solution includes a dense-phase transport design that minimizes air consumption while maintaining stable material flow. A custom-engineered rotary valve and wear-resistant piping extend service life, while a centralized PLC controller enables remote monitoring and automatic adjustment of conveying parameters.

Key Outcomes

After installation, dust emissions at the conveying area dropped to near zero, meeting environmental compliance standards. Equipment maintenance intervals increased from 2 weeks to over 6 months. The precise feeding control improved desulfurization reagent utilization by 12%, reducing overall lime consumption and operating expenses.
