在催化剂的微型评选过程中,为了分析烃类水蒸汽转化催化剂中钾流失数量及速度,必须定时地进行冷凝液的取样分析。为减轻环境污染,简化操作,提高自动化水平,特设计了这套简易自动液体取样装置。一、装置的特点:1、取样间隔为0.5～2小时连续可调。2、气水分离器中积存的液体样品可一次取清,最大样品量为1000毫升。3、连续工作时间在800小时以上。4、装置可按自动或手动方式操作。二、装置的结构及原理:装置由电子时间程序控制器、八通道液
In the catalyst mini-selection process, in order to analyze the amount and rate of loss of potassium in the hydrocarbon steam reforming catalyst, sampling analysis of the condensate must be carried out on a regular basis. In order to reduce environmental pollution, simplify operations, improve automation, especially designed this simple automatic liquid sampling device. First, the device features: 1, sampling interval of 0.5 to 2 hours continuously adjustable. 2, liquid-gas separator can be stored in a liquid sample to clear, the maximum sample size of 1000 ml. 3, continuous working time in 800 hours or more. 4, the device can be operated automatically or manually. Second, the device structure and principle: The device by the electronic time program controller, eight channel liquid
