Design And Application Of Chemica Agent Alarm Based On Flame Photometric Detection Technology

Due to the emergence of current chemical and biological weapons,chemical gas leaks and explosion accidents,the human lives are threatened.In order to detect the presence of toxic gases in a timely manner,special chemical alarms based on the principle of flame photometric detection were developed.According to the characteristics of flame photometric detector with high sensitivity,high reliability,and continuous monitoring for a long time,first of all,based on the deep analysis of the principle of the flame photometric detector adopted by the instrument and the sensitivity of the impact,the flame photometric detector was partially The optimization and reformation of the system solves problems such as the response speed and stability of the system through replenishment and dehumidification technology,gas path measurement technology,pressure measurement and control technology,etc.The detection of hydrogen flame state and auto-ignition technology solves the problem of system leakage due to flameout.Report problems;developed system self-diagnosis and automatic processing functions to improve the level of system intelligence,making the operation simple and high reliability.In this way,the flow rate of hydrogen and air in the detector is finally determined,and the air circuit system,circuit system,and software system of the instrument are designed according to the characteristics of the test object.Secondly,this paper discusses in detail the principle of response of flame photometric detector to phosphorus and sulfur.It introduces the selection of detectors,the structure of the combustion chamber,the ignition device,the flame detection device and the design of the photoelectric conversion device.It elaborates on the control system and data.The principle design of the acquisition system.Finally,this paper describes the advanced settings and operational applications of the poison alarm in the process of use,and also makes an objective assessment of the test data of its main performance indicators.
