In recent years, the domestic powder conveying pump industry has intensified research and development of new pneumatic ash conveying technologies. A number of new powder conveying pumps represented by low-pressure continuous ash conveying and energy-saving ash conveying pump sealing systems and other technological innovations It makes the model of pneumatic conveying compelling, which not only creates better conditions for pneumatic ash conveying to achieve low emissions and energy saving, but also greatly improves the technical economy of the product.
Pneumatic conveying material-sealed pump is an important conveying method in the industry today. Gravity plays an important role in the flow process and affects various movement states of powder conveyance. The factors affecting the mass flow during the flow of the orifice are analyzed. The reason for the blockage of the supply port of the silo. For continuous flow on the free surface, the chute flow and jumping phenomenon are analyzed. Because the powder conveying pump has the unique advantage of continuous conveying, it has been a coal ash power plant and other industrial pneumatic ash conveying options for a long time The main way. A large number of practical applications of powder conveying pumps in coal-fired power plants in China show that as long as the selection and design is reasonable and sufficient transportation capacity is ensured, the powder conveying pump can meet the emission requirements as an ash conveying device. We have reason to believe that with the development and application of new pneumatic powder conveying technologies, powder conveying pumps will continue to improve their dust removal efficiency and reduce energy consumption, becoming the main force of pneumatic dust conveyance in China. Military and made more achievements in energy conservation and emission reduction.
