Our company’s Dust Pneumatic Conveying System is a new type of low-pressure Dust Pneumatic Conveying System developed based on the introduction of foreign advanced technology and targeting various problems existing in different types of pneumatic conveying equipment in domestic industries. This Dust Pneumatic Conveying System is widely used in pneumatic ash removal systems in steel plants, thermal power plants, and cogeneration plants; powder material conveying in hydraulic and hydropower construction sites and urban commercial concrete mixing towers and stations; cement homogenization and transfer; conveying of various powdery materials; and powder material conveying and transfer processes in metallurgy, chemicals, building materials, ports and other industries. Our company’s Dust Pneumatic Conveying System has been successfully applied in numerous powder engineering projects and is one of the ideal pneumatic conveying equipment for powdery materials.
Our company’s Dust Pneumatic Conveying System utilizes the principle of pneumatic pressure difference combined with jet flow technology and fluidization technology, fully absorbing the theory of modern pneumatic conveying. After years of operational practice summary, it is a dedicated equipment developed for the pneumatic conveying process system of powders, where a large amount requires continuous conveying. Compared with other pneumatic conveying equipment such as vessel pumps, this equipment has the following characteristics:
Simple Structure, Reliable Operation
The low-pressure Dust Pneumatic Conveying System allows material to enter the pneumatic conveying system from atmospheric pressure. Using a uniquely designed injection device, the material is fed into the conveying pipe, and the pneumatic pressure difference is used to send the material along the pipeline to the receiving destination. The overall structure is simple, and the operation is extremely reliable.
Low Wear, Long Service Life
Due to the use of continuous conveying, low pressure and large air volume, the flow velocity in the pipe is low and constant, resulting in low wear and long service life of the entire system equipment.
Convenient and Flexible Layout
It can be arranged into single pump single pipe, multiple pumps sharing one pipe, multiple pumps sharing one air source and other forms according to the specific situation of the system. Pipelines can be arranged horizontally, vertically, or inclined upward to meet the ever-changing layout requirements of the project.
Fully Sealed, Pollution-Free Conveying, Meeting Environmental Requirements and Project Quality Requirements for the Conveyed Material
Since the system uses low-pressure, fully sealed conveying, external substances cannot enter the pipe, so it will not cause any change in the properties of the required material.
Stable Conveying
Due to the use of continuous conveying with low pressure and large air volume, there is no pipe blockage phenomenon.
Simple Operation
Since the system only requires matching Roots blowers, the main control only requires “start” and “stop” operations. It can achieve manual attendance, only requiring patrol. The continuous conveying process system is simple, so the configured control system is very simple to operate.
Low Requirement for Air Source Quality
Due to the use of continuous conveying form, and the conveying power air source generally uses Roots blowers (because Roots blowers do not contain water or oil), the power air source generally does not require a purification system, only requiring certain air volume and pressure. Independent air sources or commonly used air compressor station air sources (centralized air source) in projects can be used.
High System Reliability
The low-pressure pneumatic continuous conveying system has a reliability that cannot be achieved by any conveying system composed of other pneumatic conveying equipment. This is because: low-pressure continuous conveying systems generally use Roots blowers (high-pressure centrifugal fans or air compressors can also be used depending on the situation). The high reliability of Roots blowers determines the reliability of the system.
The equipment body is simple, without the frequent action of valves in conventional pneumatic conveying processes, greatly reducing the equipment failure rate.
The pneumatic conveying system composed of low-pressure pneumatic conveying equipment material seal pumps generally has fewer equipment quantities and types, making the entire system simple and reliable.
Continuous conveying pressure is stable, without any impact load.
Economical and Reasonable, Low Cost, Low System Operating Cost
The low-pressure continuous pneumatic conveying system, due to the above characteristics, also has the characteristics of low cost and superior operating indicators. Therefore, the superiority of this system: not only reflects its investment savings when the project starts, but also continuously reflects lower operation and maintenance costs in the future operation and use process!
Selection Principles
To select a low-pressure pneumatic conveying equipment material seal pump as the core equipment to form a pneumatic conveying system, first, the user should provide: system required conveying capacity, conveying distance, or material physical and chemical parameters, maximum temperature and normal working temperature; if under a boiler dust collector, basic parameters such as dust collector hopper layout and ash distribution should be provided. Then our factory technicians will first determine the basic conveying plan, such as required air volume, how to group, continuous pump model, air intake and conveying pipeline configuration, silo top dust collector configuration, and finally reviewed and determined by the user.
Applicable Conditions
The low-pressure pneumatic conveying equipment material seal pump, due to the use of low-pressure conveying, has certain limitations in its application range. It can only operate normally and safely and achieve the intended effect under the following conditions.
Conveying distance ≤ 500m (equivalent distance).
Material specific gravity ≤ 2.0 t/m³ (material).
Maximum series pumps not exceeding 4 units (i.e., 4 units share one ash conveying pipe).
Maximum instantaneous material temperature ≤ 250°C.
