Carrier gas purification filter pipe for oxygen-nitrogen-hydrogen analyzer, furnace head and oxygen-nitrogen-hydrogen analyzer

Abstract

The invention relates to a carrier gas purification filter pipe for an oxygen-nitrogen-hydrogen analyzer, a furnace head and an oxygen-nitrogen-hydrogen analyzer, and belongs to the technical field of oxygen-nitrogen-hydrogen analysis. The carrier gas purification filter pipe for the oxygen-nitrogen-hydrogen analyzer comprises a filter pipe and a filtering material arranged in the filter pipe and used for filtering gas, as well as a linear displacement detector used for detecting the displacement of the filtering material. According to the carrier gas purification filter pipe for the oxygen-nitrogen-hydrogen analyzer, the linear displacement detector is used for precisely displaying the amount of graphite powder adsorbed by the filtering material in the filter pipe, and the filtering material can be timely replaced, so that the precision of an analysis result is improved, and the analysis cost is reduced.

Description

technical field [0001] The invention relates to a carrier gas purification filter tube for an oxygen, nitrogen and hydrogen analyzer, a furnace head and an oxygen, nitrogen and hydrogen analyzer, belonging to the technical field of oxygen, nitrogen and hydrogen analysis. Background technique [0002] Oxygen and nitrogen are the most important elements affecting the quality of titanium alloy products. Usually, the content of oxygen, nitrogen and hydrogen in titanium alloys is detected and analyzed by an oxygen, nitrogen and hydrogen analyzer. The oxygen, nitrogen and hydrogen analyzer in the prior art includes a furnace head, and the furnace head includes a furnace body. The furnace body has a furnace chamber inside, and a graphite crucible for holding samples is arranged in the furnace chamber. The carrier gas purification filter tube for the internal output gas, the upper electrode and the lower electrode, and the furnace head also includes a temperature detector for detect...

AI Technical Summary

Problems solved by technology

However, the content of graphite powder observed by the naked eye is very inaccurate and cannot be judged quantitatively. In order to improve the accuracy of the test analysis, the quartz wool is generally replaced when the amount of graphite powder adsorbed by the quartz wool is not too much, resulting in frequent replacement of the quartz wool and increasing the test time. cost
