Industry-adapted silo for fly ash storage

- Storage capacity and specification diversity

We can provide 1000 - 50000m³ various specifications of fly ash steel plate silo, which can meet the demand of different scale enterprises or projects for fly ash storage capacity. Whether it is a small amount of storage needs of small factories or large-scale reserve requirements of large enterprises, you can find the right specifications, the silo structure is reasonably designed, and the space utilization rate is high.

- System Integrity and Synergy

The fly ash storage and transportation system covers a number of components such as large steel plate silos, pneumatic conveying inlet piping, silo top dust collector, material level instrumentation, pressure release valve, fluidized discharge system at the bottom of the silo, as well as conveying equipment and small issuing silos. The components work together, the pneumatic conveying feeding pipeline can efficiently convey the fly ash into the silo, the silo top dust collector effectively filters the dust to keep the environment clean, the material level instrument accurately monitors the material level, the pressure release valve ensures the pressure inside the silo is stable, the silo bottom fluidization discharging system ensures the discharging of the material smoothly, and the conveying equipment and the small distribution silo are convenient for the subsequent issuance and transportation, so that the overall system operates stably and reliably.

- Construction and Investment Advantages

Short construction period, compared with traditional fly ash storage facilities, the use of steel plate silo and supporting systems can significantly shorten the construction time, so that enterprises can be put into production and operation more quickly to seize the market opportunity. Low investment cost, under the premise of guaranteeing the storage and conveying function, through the optimization of design and material selection, it reduces the overall construction and operation cost, and creates income for customers to the maximum extent.

 

- Steel plate silo

The volume range is 1000 - 50000m³, the thickness of steel plate is selected between 3 - 12mm according to the size of the silo and bearing pressure, the diameter of the silo can be between 10 - 50m, the height depends on the site and capacity requirements, generally between 10 - 40m, the design pressure resistance is between 0.5 - 2kPa, which is able to withstand the pressure of the accumulation of the fly ash and a certain degree of pressure from the external environment.

- Pneumatic conveying feed pipe

The conveying capacity is between 10 - 100t/h, the conveying wind speed is between 10 - 30m/s, and the diameter of the pipe is between 100 - 300mm, which is adjusted according to the conveying distance and the characteristics of the fly ash, so as to ensure that the fly ash can be conveyed into the silo smoothly and efficiently.

- Bottom Fluidized Discharge System

The pressure of fluidizing air is between 0.05 - 0.2MPa, the opening rate of fluidizing plate is between 10% - 30%, and the discharging speed is between 5 - 50t/h. By controlling the pressure and flow rate of the fluidizing air, it can make the fly ash form a fluidized state at the bottom of the silo, which is convenient for discharging.

 

- Electric power industry: Thermal power plants produce a large amount of fly ash in the process of power generation, the storage and transportation system can be used for storing and subsequent processing of fly ash produced by the power plant, which is convenient for comprehensive utilization of fly ash or selling it to other enterprises for secondary processing, such as the production of fly ash cement, fly ash bricks and other building materials.

- Building materials industry: Cement factories, concrete mixing stations and other building materials enterprises can utilize the system to store fly ash and use it as an auxiliary raw material for the production of cement and concrete, which improves the performance of the products, reduces the production cost and improves the competitiveness of the enterprises.

- Environmental protection industry: In some environmental protection projects, such as landfill treatment of fly ash or resource recycling project of fly ash, the storage system can play the role of storage and transit, which helps to promote the environmental protection treatment of fly ash and resource recycling.

 

- Steel plate silo installation and maintenance

During the installation of the steel plate silo, it is necessary to ensure the firmness and levelness of the foundation, and carry out accurate construction according to the design requirements, so as to avoid tilting or sinking of the silo body due to foundation problems. Regularly check the appearance of the Steel Plate Warehouse to see if there is rust, deformation, etc. For minor rust, rust removal and anti-corrosion treatment should be carried out in a timely manner, and for the deformed parts, the impact on the structure and performance of the warehouse should be assessed, and if necessary, repaired or reinforced.

- Pneumatic conveying and fluidization system

Pneumatic conveying feed pipe should be cleaned regularly to prevent accumulation of fly ash in the pipe to block the pipe and affect the conveying efficiency. Periodic blowing or installation of blockage clearing device can be used for prevention. The fluidization discharge system at the bottom of the silo should pay attention to the stability and cleanliness of the fluidization air source to avoid poor fluidization effect or damage to the fluidization equipment due to insufficient air pressure or impurities, regularly check the permeability and integrity of the fluidization plate, and clean up or replace it in time if there is any clogging or breakage.

- System safety and monitoring

To ensure the normal operation of the silo top dust collector, pressure release valve and other safety equipment, regular inspection and maintenance, to ensure that it can play a role in time when the pressure in the silo is abnormal or the dust exceeds the standard. The material level instrument should be calibrated regularly to ensure the accuracy of material level monitoring, so as to reasonably arrange the inlet and outlet operation of fly ash and prevent accidents such as bubble silo or empty silo due to the error of material level monitoring.
