Pneumatic Conveying Pump Equipment For Cement, Coal Powder, Carbon Powder Silo

Description

Working principle of pneumatic ash conveying system with silo pump
The pneumatic ash conveying system is a widely used pneumatic conveying engineering system. It is a commonly used conveying system in the power plant industry, metallurgical industry, and other industries.
Feeding stage: The feeding valve is in an open state, and the primary inlet and outlet valves are closed. The upper part of the bin pump is connected to the ash hopper, and the fly ash captured by the dust collector freely falls into the bin pump with the help of gravity. When the ash level reaches the upper limit of the ash level, the material level meter sends a full signal, or when the system feeding setting time is set, the feeding valve is closed, and the feeding stage ends.
Fluidization and pressurization stage: After the feeding stage is completed, the system automatically opens the inlet valve once. The processed compressed air enters the fluidization cone at the bottom of the bin pump through the flow control valve, and the air passing through the fluidization cone evenly surrounds each fly ash particle. At the same time, the pressure inside the bin pump increases. When the pressure reaches the point where the pressure sensor sends a signal, the system automatically opens the discharge valve, and the pressurized fluidization stage ends.
Delivery stage:
The discharge valve and secondary inlet valve are opened. At this time, the bin pump continues to intake air while feeding the gas-ash mixture into the ash conveying pipe through the discharge valve. The fly ash is always in a state of fluidization and entering the conveying pipeline for transportation. After the fly ash in the bin pump is transported, the pipeline pressure drops, and the pressure inside the bin pump decreases. When the pressure inside the bin pump drops to the point where the pressure sensor sends a signal, the conveying stage ends, and the inlet and outlet valves remain open, Enter the blowing phase.

Introduction:
After years of research and rich practical experience, our company has developed pneumatic conveying equipment and process systems with independent intellectual property rights for PCD type positive pressure dense phase pneumatic conveying silo pumps. Its main indicators have reached the international advanced level. The volume of the pump is determined based on the properties, particle size, conveying distance, and conveying capacity of the conveyed material, which means designing a single unit to minimize conveying energy consumption while meeting process requirements. Based on the specifications and performance of powder materials provided by customers, conveying distance, conveying volume, and geographical conditions, we have developed the best plan for pneumatic conveying, including calculation of air volume, proportion of pipelines, dust collection treatment in the receiving warehouse, and after-sales plan.

Main features of the product
① Large conveying capacity: ＞ 300t/h;
② Long distance: ＞ 2000m;
③ Low power consumption: ＜ 3.8kWh/t · km;
④ Low wear and tear: pipeline life>10 years;
⑤ Low speed: initial speed 6-10m/s;
⑥ High mixing ratio: ＞ 30kg/kg;
⑦ Flexible process layout, dust-free, high operation rate, lower investment compared to mechanical conveying, and lower maintenance costs

Application Area
