The conveying method of pneumatic conveying system
? ? ?in usepneumatic conveyingDuring the process, gas is used as a carrier to transport materials to the desired destination through airflow, where the shape of the materials changes with the airflow. When the conveying wind speed is high, the material is evenly suspended and transported through airflow; As the flow rate decreases, materials begin to aggregate and are transported in the form of sand dunes within the pipeline; When the airflow velocity decreases again, the pipeline is blocked by the cross-section of the material, forming an unstable plug shape; At this point, the material plug is pushed and transported by air pressure; When the wind speed decreases again, unstable plugs will form stable plugs, usually driven by air pressure. The material can be evenly distributed in the vertical pipeline, and the boundary between the dilute phase and the dense phase is the boundary between the material flying and transported in the water quality pipe.
Experts from Juheng have divided the entire pneumatic conveying system into four parts. Below is a detailed explanation of each part:
? ?1、 Dilute phase pneumatic conveying: With high wind speed, the material suspension is evenly distributed in the lead pipe and flies in horizontal conveying, resulting in a high porosity. The conveying of materials mainly relies on the energy carried by high-speed airflow.
? ?2、 Dense phase pneumatic conveying: The material is no longer evenly distributed in the pipeline, but is dense, but the pipeline is not blocked by the material and still relies on airflow to maintain energy transport
? ?3、 Plug flow pneumatic conveying: This is currently the best medium distance conveying method in pneumatic conveying. Manually cut the material bolts into shorter ones using air pressure in advance. The material bolts are separated by pneumatic bolts and continuously propelled by static pressure. As a result, the speed of material bolts has been increased, the conveying pressure has been reduced, and power consumption has been lowered.
? ?4、 Container type pneumatic conveying: Similar to bolt pneumatic conveying, it uses air pressure to quickly transport the conveying drum or container truck in the pipeline.
? ? Therefore, although the pneumatic conveying system has a simple structure and is easy to maintain, the design of pneumatic conveying is a huge and complex project. It not only needs to consider the materials conveyed, but also the site and pipeline design of the conveying, as well as the design of materials science, fluid science, aerodynamics and other aspects. Therefore, it is still necessary to choose a powerful manufacturer,Shandong Juheng Environmental Protection Equipment Co., LtdWelcome to your consultation!
