Desulfurization gypsum, a byproduct of flue gas desulfurization in power plants, is widely utilized in construction materials, agricultural applications, and other industrial sectors. The efficient transportation of this material is critical for the smooth operation of industrial processes. This article provides a detailed overview of the operation process and working principle of a pneumatic conveying system specifically designed for desulfurization gypsum, manufactured by Shandong HeadPowder Engineering Co., Ltd., a leading enterprise in China specializing in industrial conveying solutions.

Operation Process of the Pneumatic Conveying System

The pneumatic conveying system for desulfurization gypsum operates through a systematic sequence of steps to transport the material from its storage location to the processing or application site. The process initiates with the loading of gypsum into the system's hopper, where it is stored under controlled environmental conditions to maintain material quality. Once the system is activated, the material is fed into the conveying line via a rotary valve or feeder, which regulates the flow rate. Simultaneously, a high-pressure air blower generates the necessary airflow to move the gypsum particles through the pipeline. The conveying line is typically equipped with bends, filters, and pressure relief valves to ensure system efficiency, safety, and consistent performance. The material is then discharged at the destination, where it can be further processed or utilized as a raw material in various applications.

Working Principle of the Pneumatic Conveying System

The fundamental principle of the pneumatic conveying system is the use of air as the conveying medium to transport solid particles. The system operates by creating a pressure differential between the inlet and outlet of the conveying line. The air blower supplies compressed air, which creates a negative pressure in the pipeline, effectively drawing the gypsum particles into the air stream. The particles are suspended in the airflow and transported to the destination. The system may employ different conveying modes, such as dilute phase or dense phase, based on the material characteristics and the distance to be covered. The dilute phase system is suitable for short distances and low material loads, while the dense phase system is used for longer distances and higher material loads, ensuring stable and efficient transport. This mode selection is crucial for optimizing system performance and minimizing energy consumption.
