背景技术
空分冷箱为空分设备中不可或缺的部分,其主要组成部分由主塔、氩塔及主换热器及相关管道及阀门。空分冷箱内各类塔器及管道内存在大量低温液体,由于低温液体沸点极低,故当空分冷箱内阀门、管道存在泄漏时,低温液体极易挥发,造成空分冷箱砂爆事故。
实用新型内容
本实用新型目的是提供一种空分冷箱含氧量监测与泄放装置,实时监测空分冷箱内氧含量及在氧含量超过安全警戒值时能够及时泄放空分冷箱内氧组分,防止空分冷箱砂爆,有效地解决了背景技术中存在的上述问题。

一种空分冷箱含氧量监测与泄放装置,包含主塔、氩塔、主换热器、冷箱、气体收集与泄放罐、主管道、分支管道一、分支管道二、分支管道三、自动分析仪和消音器,所述主塔、氩塔和主换热器均设置在冷箱中,主塔、氩塔和主换热器底部均设有气体收集与泄放罐,主塔、氩塔和主换热器底部的气体收集与泄放罐分别与分支管道一、分支管道二和分支管道三一端连接,分支管道一、分支管道二和分支管道三的另一端均与主管道一端连接,主管道另一端引出冷箱外,引出后分为两路,一路连接至自动分析仪,另一路连接至消音器。
所述主管道另一端引出后分为两路,分别为监测管路和泄放管路,监测管路通过阀门二与自动分析仪连接,泄放管路通过阀门一与消音器连接。
本实用新型能够及时发现空分冷箱内是否存在泄漏,并在发生泄漏时快速将冷箱内危险气体泄放出来,达到空分冷箱安全、平稳运行。通过在冷箱内主塔、氩塔和主换热器底部分别安装一个气体收集与泄放罐,并用相应管道相连接后引出冷箱外,引出后一路通过阀门二连接至自动分析仪,做到实时监控;另一路通过阀门一连接至消音器,在发生冷箱内部泄漏时泄放冷箱内气体。
本实用新型的积极效果:既可以连续监测冷箱内氧含量又可以在冷箱内存在泄漏时安全、快速地泄放危险气体,防止砂爆的发生。
