Pneumatic conveying is a very complex multiphase flow management process, and the movement of solid particles inside the conveying pipe involves various economic conditions such as the distribution of airflow development speed and the friction between solid particles and the pipe wall. The transportation pipeline not only involves the suspension of solid particles during rolling motion, but also the occurrence of solid particles. The collision between the solid particles and the wall of the solid particles generates a lifting force that further rotates. It is very complex to fully consider these issues. For a long time, people have conducted a lot of analysis and research in this field, but there are still many social problems that we have not been able to solve well, such as the information between solid particles and the collision between solid particles and the pipe wall during the process of scattered materials being carried away by airflow in pipelines. The collision results in solid particle breakage and pipeline wear caused by enterprises. This learning situation becomes increasingly evident at high speeds.

To alleviate these phenomena, the speed of the conveying airflow can be reduced, but with it comes the instability of the flow, which can lead to blockage. In addition, the conveying efficiency of the system is also an important issue. The material, hardness, and capacity of the conveying system are almost negligible, and the damage and viscosity of the conveying system are superior to those of the conveying system itself. When considering the effect from the perspective of size integration to determine the efficiency of pneumatic conveying, it becomes very complex. The gas solid flow conditions of the system directly affect the stability and effective operation of the system. Therefore, in order to optimize the design of the pneumatic conveying system, it is necessary to master the solid flow characteristics and rules during system operation, conduct in-depth research, and study the flow problems of solid particles in pipelines.

In the research of pneumatic conveying, the blockage of pneumatic and conveying system equipment through pipelines is an important and complex issue. If the pneumatic conveying system or the system deviation from normal operating conditions is designed unreasonably, blockage may occur during operation. Sudden blockages will affect normal production; In severe cases, it will cause the management system to stop running, affecting the normal production and equipment information security of the enterprise, and causing social and economic losses. At present, there is a lack of in-depth research on the prevention and control mechanisms of pipeline blockages both domestically and internationally. The current system design has experienced a trial and error approach that increases operating costs; The second is not taking proactive measures to control congestion. After the blockage problem occurs, in order to eliminate it, production can be carried out by suspending work and flushing air to eliminate blockage. Some studies have also used the method of introducing air midway to eliminate blockage, but the operating system is complex and also increases costs.
