在现代化工生产中,除个别固体物料输送需要用皮带机或是刮板机输送外,其他物料都是通过管线进行输送。管线运输,它具有运输效率高、成本低、损耗少和对环境污染小等优点。但是管线输运也存在一定问题,就是管道清理工作。目前管道一般采用收发球筒及清管阀进行清理,这一点在大型储罐区应用很多,本文就收发球筒及清管阀在储罐区生产中优缺点进行比较。
In modern chemical production, in addition to individual solid materials need to convey belt conveyor or scraper, the other materials are transported through the pipeline. Pipeline transportation, it has the advantages of high transportation efficiency, low cost, less loss and less environmental pollution. However, pipeline transportation also has some problems, that is, pipeline cleaning. At present, pipes are usually cleaned by the receiving and dispatching spheres and the pipe cleaning valve. This is widely used in large tank areas. This article compares the advantages and disadvantages of the receiving and sending spheres and the pigging valve in the production of the tank area.
