| 摘 要： | 由于分子筛吸附器筛网格栅与支撑环板连接处存有裂缝,使氧化铝颗粒泄漏到出口,并从污氮放空消声器处吹出;由于分子筛吸附器不锈钢内胆有裂缝,造成部分仅经氧化铝吸附的空气从漏点进夹层短路到分子筛吸附器空气出口管,从而使出分子筛吸附器空气中的二氧化碳含量超标。文章介绍了这两起故障的现象及处理方法。

Cause and treatment of two malfunctions in molecular sieve adsorber |
| |
| Abstract: | The alumina granules leak to the outlet of molecular sieve adsorber and escape from exhaust silencer of waste nitrogen, due to the crack at the joint between sieve spacing grid and supporting ringy plate. The crack at the stainless steel inner liner in molecular sieve adsorber permits part of the adsorbed air (only through alumina) shorts from the leak point to air outlet pipe of molecular sieve adsorber, which leads to the transnormal carbon dioxide content in outlet air. The phenomena and treating measures are presented. |
