浅析烧碱装置喷油螺杆空压机的应用及选型史晓蒸
(中国成达工程有限公司,四川成都610041)
[摘要]:螺杆空压机因其具有结构紧漆、外形美观、振动小、效率高、棒气压力稳定、能耗小、噪声低和使用寿命长等特点,在化工行业得到了愈来念广泛的应用。因烧碱装置压缩空气用户允许搬量油存在,且因喷油螺杆空压机较无油螺杆空压机单级压比高、价格低等优势而使其应用较为鲁遍。介绍了喷油螺杆空压机在烧碱装置中的应用,并对其选型及主要技术参数比较进行了分析总结,以此作为今后类似选型设计工作的参考。

空压机是工业现代化的基础产品,用于提供气源动力,是气动系统的核心设备,是压缩空气的气压发生装置。化工行业的烧碱装置中,通常会采用空压机,用空气压缩的办法制得合格的空气,部分空气以一定压力,一定油含量、水含量等指标进人空气储气罐,部分去工艺压缩空气管道,部分则经再生干燥后供仪表及特殊要求的工艺管线吹扫用,亦有部分通过制氮系统后制得合

空压机的型式比较及螺杆空压机在烧碱 2
装置中的应用
空压机主要有活塞式、螺杆式和离心式等类型。活塞空压机排气压力不够稳定,排气温度高;产热量、排油量较多,影响环境;有一定振动,噪声、占地面积较大!;电机功率偏大;且带底座,需用地脚螺栓固定在基础上:检修工作量大,维修费用高。另外,活塞空压机经使用一段时间后,会因磨损造成泄漏从而使排气量降低,如选型时裕量考虑不够,会造成实际运行期间气量不足,影响生产效率,有时可能还需增加小排气量空压机满足工艺需要,从而造成额外投资。
