High altitude airborne X fluorescence real-time analyzer

Abstract

The invention relates to a high altitude airborne X fluorescence real-time analyzer, which includes an excitation source, a sampling membrane, a detection device, a power supply, a wireless transmission device, and a processor. Specifically, the excitation source includes a micro-isotope X ray source and a collimator in fixed connection. The rays emitted by the emission source irradiate on the sampling membrane, and are reflected to the detection device. The detection device comprises a micro-silicon drift detector and a micro-digital multichannel spectrometer that are connected in order, and the rays enter the micro-digital multichannel spectrometer through the micro-silicon drift detector. The wireless transmission device sends the information processed by the detection device into the processor, and the power supply provides power to the detection device and the wireless transmission device. The analyzer provided by the invention employs the X fluorescence method to conduct real-time fast detection on heavy metal particle samples at a high altitude sewage outlet by an aircraft, and has the advantages of simple operation, real-time and fast measurement, wide detection range, and low detection limit, and realizes real-time monitoring of high altitude pollutants.

Description

technical field [0001] The invention relates to the field of real-time detection and analysis of high-altitude pollutants, in particular to a high-altitude airborne X-ray fluorescence real-time analyzer. Background technique [0002] my country's smog weather is becoming more and more frequent and severe, and the main root cause is the extensive use of fossil energy. The combustion of a huge amount of coal will produce a large amount of toxic and harmful substances, among which trace heavy metal elements are very harmful to human beings and the environment. The surface of submicron particles is discharged into the atmosphere along with submicron particles, and exists in the form of aerosol for a long time, which is not easy to settle, which not only affects the visibility of the atmosphere, but also makes people and other organisms harmed by heavy metals. These burned pollutants are basically discharged to the high altitude through the chimney. If the high-altitude sewage o...

Problems solved by technology

However, most of the X-ray fluorescence equipment in the experiment is very heavy. Even a small portable X-ray fluorescence equipment weighs 2-3kg. How to develop X-ray fluorescence equipment with smaller volume and weight and apply it to high-altitude real-time analysis is a major difficulty. Therefore, It is necessary to improve the existing technology to solve the deficiencies of the existing technology
