元坝气田天然气中高含硫(H2S),所有进入场站的施工调试人员必须佩带好正压式空气呼吸器,每次使用30分钟左右就需要给气瓶充气,每次充装时间为15-20分钟。梅思安空气充气泵过滤系统中的中心滤芯为充气泵易耗件,充装8小时就需要更换,有的场站一天就需要更换2-3个,成本非常高。通过对滤芯进行结构、成分分析,发现了中心滤芯能够具有重复利用的价值,通过改变更换方式和调整滤芯组分配比,可以提高滤芯的过滤效果,降低运行成本。
Yuanba gas field high sulfur (H2S), all the construction site commissioning and commissioning personnel must wear a positive pressure type air respirator, each use for about 30 minutes on the need to inflate the gas bottle, each filling time is 15- 20 minutes. Meisian air pump filter system center for the inflator consumables consumables, filling 8 hours need to be replaced, and some stations need to be replaced one day 2-3, the cost is very high. By analyzing the structure and composition of the filter, it was found that the central filter can be reused. By changing the replacement mode and adjusting the ratio of the filter elements, the filtering effect of the filter element can be improved and the operating cost can be reduced.
