Pressure loss in pipelines: During the entire process of powder transportation, gas and raw materials will experience working pressure loss in pipelines, which is included in the losses in horizontal and vertical pipelines. The key is the friction between gas and raw materials and wall thickness, the impact and friction between them, and the necessary cost of maintaining the floating of raw materials. In vertical pipelines, it is also necessary to get rid of the consumption caused by the floating of raw materials

The longer the pipeline, the greater the level of loss.

The pressure loss during the acceleration of raw materials: The entire process of accelerating the transported raw materials from being stationary to starting and exceeding the steady transportation speed must consume relative cyclonic kinetic energy, which also leads to the working pressure loss during the entire powder transportation process. Pressure loss in bent pipes: The pipes in pneumatic conveying systems cannot be guaranteed to be completely horizontal or vertical, and may undergo bending and other changes depending on the specific situation. When encountering such situations, the gas and raw materials will experience braking throughout the transportation process. At this time, due to the effect of inertial force and centripetal force, the gas and raw materials will collide with the wall thickness and change direction to spread and start again, resulting in a significant loss of working pressure.

Pressure loss caused by supporting facilities, components, and machinery equipment: Powder conveying is a complete system software that requires the coordination of several supporting facilities, components, and machinery equipment such as mufflers, material gas separation, and ash removal. However, excessive noise reduction, mid to late stage ash removal, and material gas separation all consume kinetic energy, leading to work pressure loss. When encountering the problem of dust being unable to be discharged by pneumatic conveying, there is no need to worry. First, check the operation of the pneumatic conveying and whether the equipment is damaged. If it is not based on experience and technical analysis, you can directly contact the manufacturer's technical personnel to check the situation. The technical personnel will analyze the causes and solutions of the problem. The main problem of non emission in pneumatic conveying is a few issues.

1. Material characteristics: high viscosity, high moisture content, poor material flowability; 2. The diameter of the feeding tube is narrow, which affects the feeding process. 3. The angle of the feeding tube is not matched correctly; 4. Too much gas and gas used for fluidization;

terms of settlement:

1. Choose the appropriate feeding method based on the material characteristics;

2. Increase the diameter of the ash pipe;

3. Increase the feeding angle; 4. Adjust the air delivery.
