On July 31, the system designed, manufactured, and installed by Guangzhou Aogong Spray Equipment Co., Ltd. The dry‑mist dust suppression system for the coal‑conveying belt has officially entered the commissioning and operation phase. Stage

Coal transportation at the coal yard of Shougang Jingtang Thermal Power Operation Area Belt System Dry-Mist Dust Suppression Complete Set System , in response to national environmental protection requirements, aims to prevent dust emissions during the operation of the coal-handling system at the thermal power plant’s coal yard. As a key project under Shougang Jingtang’s initiative to achieve Environmental Protection Grade A certification, Dry-mist dust suppression Once the system is officially put into operation, it will effectively improve the working environment in the thermoelectric district.

The system employs “Aogong” brand micron-level components. Spray‑equipment products featuring domestically leading technologies—such as dry‑mist dust suppression systems and ultrasonic oscillation nozzles for dry‑mist dust control—have been extensively applied and demonstrated within this system. The complete dry‑mist dust‑suppression unit supports both manual and fully automatic control modes; in automatic mode, the system’s programmable logic controller adjusts operations based on real‑time site conditions, enabling unmanned operation. Okay, this will reduce the physical workload of on-site operators. According to measurements, At the time of system commissioning, the ambient dust concentration outside the dust suppression zone of the belt transfer station was ≤5 mg/Nm³; the dry‑mist dust suppression system consumes minimal water, and the increase in material moisture by weight is less than 0.05%. Furthermore, the nozzles within the spray‑nozzle assembly feature a self‑cleaning function, and the dry‑mist dust suppression system incorporates a blow‑down and freeze‑protection capability, both of which meet the project’s design and operational requirements.
