Principle of Denitrization Fly Ash Pneumatic Conveying Systems

The operation of a denitrization fly ash pneumatic conveying system is based on the fundamental principle of using compressed air or gas to transport particulate materials through a pipeline network. The system functions by creating a pressure differential between the material source and the destination, which allows the material to be entrained and carried by the air flow. The process can be categorized into two primary types: dilute phase and dense phase pneumatic conveying. Dilute phase systems utilize higher air velocities to transport materials in a relatively low concentration, typically at air-to-material ratios of 5 to 10. This method is suitable for materials that are non-abrasive and can be transported over short to medium distances. In contrast, dense phase systems employ lower air velocities and higher material concentrations, often at air-to-material ratios of 1 to 2. Dense phase conveying is preferred for denitrization fly ash due to its fine particle size and abrasive nature, as it minimizes particle degradation and reduces system wear. The system components include a material feeder, a compressor or air supply unit, a pipeline network, and a discharge device. The material feeder, such as a rotary valve or screw feeder, ensures a consistent and controlled flow of fly ash into the system. The compressor, which can be a positive displacement or centrifugal type, provides the necessary pressure to move the material through the pipeline. The pipeline network, typically made of stainless steel or other corrosion-resistant materials, transports the material from the source to the destination. The discharge device, such as a rotary valve or a venturi, regulates the material's release at the end point. The control system, which may include sensors and a programmable logic controller (PLC), monitors and adjusts the air flow and material feed to maintain optimal operation. This principle ensures that denitrization fly ash can be transported safely and efficiently, reducing the need for traditional bulk handling methods like trucks or conveyors and minimizing material loss and contamination.
