Description

一种空分液空进氩塔汽提装置
技术领域
本实用新型属于空气分离领域，具体涉及一种空分液空进氩塔汽提装置。
背景技术
空气分离在工业上最常用的方法就是低温分离法。空气中的氧、氮、氩等组分在低温下通过精馏被分离出来。其中氧、氮组分通过主塔精馏被分离出来，而粗氩塔及精氩塔分别分离氩、氧组分及氩氮组分，在精氩塔底部得到纯度为99.999%的液氩产品。
随着空分设计和制造工艺的不断变革，单套空分装置生产能力更大、更安全、更节能、产品提取率也更高，但伴随生产能力扩大而来的是精馏塔越来越高，各塔之间低温液体物料输送难度越来越大，为了缓解低温液体输送问题，低温液体汽提输送技术越来越多的被采用。该技术具有设备简单可靠、投资少、节能、便于操作等优点。
目前国内小空分低温液体输送大都靠节流阀节流后压力能转化成速度能，前后的管道管径变化，可以保证低温液体获得足够的动力，并控制低温液体流速。缺点是精馏塔的高度不能过高，以及下塔压力要求高，造成空压机出口压力也需相应提高，空分的运行成本偏高。
国外部分厂家使用的是汽提阀提供与低温液体的温度和组分相近的气体通入提升管。低温液体与汽提气在节流阀后的提升管内汽液混合“密度”降低。根据连通管原理，在上下塔压差不变的情况下，提升管内“低密度液体”将升的更高。这种方法的优点是对下塔的压力要求不高，精馏塔的设计高度也可适当放高，有利于精馏。缺点是所提供的气体必须与低温液体的温度和组分相近，汽提阀及汽提管路需安装在冷箱内，设计制造安装的成本都大幅提高。
发明内容
本实用新型的目的在于提供一种空分液空进氩塔汽提装置，获得低运行成本、高可靠性的汽提气。
为达到上述目的，本实用新型的技术方案是：
一种空分液空进氩塔汽提装置，安装于空分冷箱；包括，两个液空节流阀，安装于空分冷箱，并通过管路分别连接于粗氩塔、精氩塔；第一、第二连接管路，分别对应连接于所述两个液空阀，该第一、第二连接管路上分别设有截止阀、压力表、单向阀；进气管路，其进口端连接压缩空气，出口端分别连接第一、第二连接管路；该进气管路中设控制阀。
本实用新型的有益效果：
本实用新型在空分装置正常运行阶段使用压缩空气作为冷箱液空的的汽提气，实现了低成本生产，克服原液空输送上的缺陷；保证了制氩系统的稳定运行。
