The environmental pneumatic conveying equipment belongs to low-pressure conveying systems and is widely used in cement plants and power plants. The material lock pump is compact, lightweight, and convenient to install. In pneumatic conveying systems, the selection of Roots blowers ensures the smooth operation of powder transportation through pipelines. The pipeline diameter, airflow velocity, and layout of the material lock pump directly affect energy consumption and losses. The material lock pump's conveying system can significantly improve system reliability and maintainability. While meeting the output capacity requirements, it minimizes conveying velocity to reduce wear and tear during powder material transportation.  

In thermal power plants, environmental issues arise from two primary sources: the discharge of wastewater and waste gases caused by coal combustion and the transportation of coal itself. To enhance coal utilization efficiency, most domestic power plants use fly ash for power generation. Due to its small particle size, fly ash features a high combustion rate. However, the transportation of fly ash has always been a challenging issue. Fly ash has a low relative density and is highly volatile, causing large-scale dispersion during traditional mechanical transportation. This not only severely impacts environmental quality but also decreases transportation efficiency. On the other hand, using lump coal affects coal utilization efficiency. This posed an unsolvable problem in the past.  

The emergence of Hengyun pneumatic conveying equipment has completely resolved this issue. The pneumatic conveying system adopts a brand-new fully enclosed pneumatic conveying method powered by Roots blowers. It utilizes low-pressure pneumatic conveying to deliver powdered materials to their destination. The entire process uses ceramic composite pipelines for fully enclosed transportation, effectively eliminating the problem of fly ash leakage.  

The material lock pump is highly popular and plays a crucial role in the power, metallurgy, chemical, and building materials industries. Its key features include:  

1. Simplified Configuration: The pneumatic conveying system has a simple setup with fewer rotating components. The feed valve and discharge valve are the only rotating parts. No additional auxiliary equipment is required, and ash hoppers do not need fluidization devices. The operation is flexible, allowing for continuous operation.  

2. Low-Pressure Airflow Conveying: The system adopts low-pressure airflow for conveying, consuming minimal compressed air while achieving high conveying efficiency.  

3. Low Energy Consumption: The system consumes less energy due to the lower amount of compressed air required and the reduced conveying pressure. As a result, its energy consumption is far lower compared to other pneumatic conveying systems.
