How To Solve The Problem Of Wear Of Pneumatic Conveying Pipelines?

Latest company news about How To Solve The Problem Of Wear Of Pneumatic Conveying Pipelines?

Most ash conveying pipelines use pneumatic conveying, which has the characteristics of high airflow pressure, fast flow rate, and long conveying time. There are often hard particles in the conveyed materials, which seriously wear the ash conveying pipeline. Abrasion of the ash conveying pipeline will cause serious pulverized coal leakage, pollute the environment, and cause potential safety hazards and waste materials.

There are three common solutions:

1. Reducing the air pressure during ash conveying can reduce the material flow rate while saving energy, thereby reducing pipe wear. This method reduces the efficiency of ash conveying in the pipeline, and the effect is not ideal.

2. Make a backpack patch structure in the parts where the ash conveying pipeline has been worn or may be worn, and pour cement or wear-resistant materials into the backpack. The operation is simple and the cost is low, but it can only partially solve the problem and cannot fundamentally solve the problem.

3. Improve and optimize the wear resistance of the pipeline itself. The lining of the pneumatic conveying pipeline with alumina ceramics is an effective method to solve the wear of the ash conveying pipeline. Corundum is the main component of wear-resistant ceramics. Its hardness can reach above HRA88, and the wear resistance is far super metal. The service life is 7-10 times that of metal pipes.
