[0002] Tubular membrane system is an important solid-liquid separation method in wastewater treatment. In the application, some harsh working conditions cause the membrane bundle in the tubular membrane to twist and deform, leading to operational problems and other problems. Improvements need to be made from the process technology. From the pipeline fluid, the circulation pump pumps the concentrate into the tubular membrane system to circulate water. During this period, the concentrate fluid does not circulate in a straight line. Due to the structural characteristics of the tubular membrane equipment, the fluid rotates and circulates in the pipeline. At the same time, under high pressure and high temperature, the membrane bundle in the tubular membrane twists and deforms, and the existing tubular membrane circulation pipeline system has problems with the machine frame installation. In terms of design, it is mainly characterized by reasonable layout and economy. The membrane layers and membrane rows are relatively compact, the installation spacing of pipe fittings between membrane layers is small, the centrifugal pump and pipeline installation structure and the tubular membrane are bundled with many small membrane tubes, and the two ends are blocked with PVC solid end plates.
