Product Introduction:

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.

Positive pressure dense phase intermittent pneumatic conveying system
In terms of positive pressure dense phase intermittent pneumatic conveying, the company has always been committed to theoretical research and engineering practice experience summary of pneumatic conveying systems, focusing on breaking through the key technologies of long-distance, high production, low energy consumption, and low wear in the pneumatic conveying process. The core product is the PCD type positive pressure dense phase pneumatic conveying silo pump, while providing systematic, standardized, and refined engineering design and technical services. To meet the needs of different customers, we create the best design plan based on parameters such as material properties, conveying distance, conveying capacity, receiving warehouse capacity, dust removal capacity, and geographical conditions. Each equipment is manufactured through qualified inspection, and each pneumatic conveying system has its own design features, allowing customers to truly experience the intelligent management and economic benefits brought by advanced technology products.

Advantages of PCD type positive pressure dense phase pneumatic conveying silo pump:
1. No pipe blockage
The pneumatic conveying bin pump can basically adapt to the pneumatic conveying of any powder material, and the system installed with the pneumatic conveying bin pump will not cause pipe blockage, with very high reliability. Even if you want to artificially block the pipes, it's a very difficult thing
2. Long distance pneumatic conveying
The warehouse pump can achieve ideal long-distance pneumatic conveying. Currently, in domestic cases, only the dense phase pneumatic conveying system operates stably with a conveying distance exceeding 2000 meters.
3. Low energy consumption
The conveying process of the warehouse pump only consists of three processes: feeding and pressurized conveying, omitting the step of pipeline blowing. The warehouse pump can achieve full pipe dense phase pneumatic conveying with low flow rate, and can stop conveying when there is no ash, which will not affect the next conveying process and will not block the pipeline
4. Low wear and tear
Because the flow rate of the warehouse pump is low, wear is actually proportional to the flow rate. The pneumatic conveying flow rate of the warehouse pump generally does not exceed 5m/s. Many customers who are not familiar with it generally have high conveying pressure, which increases wear. In fact, the pressure of pneumatic conveying is not related to wear. The higher the conveying speed of the material, the more severe the wear will be.
5. High efficiency
Environmental protection is also used for dilute phase pneumatic conveying, but we have to admit that for the same conveying project, the conveying capacity of the warehouse pump can be more than twice that of the dilute phase pneumatic conveying
6. Specific gravity
The concentrated phase pneumatic conveying of the combined pump has strong adaptability and can transport almost any powder.
7. Simple configuration
The configuration of the warehouse pump is very simple, and modular components can save a lot of costs.
