【技术实现步骤摘要】
一种滤膜低温运输装置
本技术涉及一种滤膜低温运输装置,具体为一种环境空气颗粒物滤膜低温运输装置。
技术介绍
环境空气颗粒物是环境污染的重要来源之一,环境空气颗粒监测分为间接自动法和溯源重量法,滤膜采样、滤膜运输是重量法重要组成部分。其中为防止环境空气颗粒物中碳、金属、有机物等污染物流失,相关标准要求滤膜运输全程要在低温下完成。现有的滤膜运输装置采用冷媒保冷的保温效果差,采用冷媒保冷,达到同等的保温效果需要耗用大量的冷媒,携带不便;采用电、液氮等保冷,不但体积大,携带不便,还不能乘坐飞机。
技术实现思路
针对现有技术中没有有效措施解决滤膜运输问题等不足,本技术提供一种可防止有机物等污染物流失的滤膜低温运输装置。为解决上述技术问题,本技术采用的技术方案是:本技术一种滤膜低温运输装置,为一真空筒状容器,外壳为真空夹层结构,外壳里侧容置滤膜筒,滤膜筒中设有多个滤膜夹盒,滤膜夹盒中放置滤膜夹;滤膜筒与外壳之间放置冷媒。真空筒状容器为金属结构,其上设有瓶盖,瓶盖与真空筒状容器瓶口螺纹连接。真空夹层里层表面为镀层。滤膜筒截面为圆形或正多边形,滤膜筒上端设滤膜筒上盖,下端设滤膜筒下盖;每个滤膜筒叠放多个滤膜夹盒。冷媒采用晶体形状,蓄冷之前为液体或絮状。真空筒状容器还设有温度记录仪,其安装于真空筒状容器内部。外壳为圆形或正多边形。真空筒状容器、温度记录仪、滤膜夹盒均设有相对应的编码,编码形式有二维码、条形码、RFID编码。本技术具有以下有益效果及优点:1.本技术可保证低温(4℃以下)情况下运输TSP、PM10、PM2.5、PM1、PM0.5等环境空气颗粒物采样中使用的滤膜,采用冷媒 ...
