Abstract

A two-channel analyzer of optically dense flammable aerosol fluxes based on two parallel diode optocouplers with a wavelength of electromagnetic radiation λ = 0.65 and 3.4 μm, a speed of τ ≤ 0.05 s and the transmission of digitized data to a server up to 1200 m away via the RS-485 interface has been developed. Its design and characteristics in the process of detecting particle streams with a diameter of 0.2 to 5000 μm with an optical density of D ≤ 3.5 are described. It is shown that the values of the ratio of wave attenuation coefficients with λ = 0.65 and 3.4 μm to the droplet size calculated on the basis of the theory of radiation scattering Mi are consistent with the experimental ones. The created aerosol analyzer can be used in the express analysis of technogenic airborne emissions of fuel liquids and for the development of large-scale generators of explosive type when creating pulse barriers from clouds of finely dispersed aerosol in the atmosphere.

快速双通道光学高密度气体排放分析器基于二极管光电光电对，波长为0.65微米和3.4微米。

研制了一种基于两个平行二极管光耦合器的光稠密可燃气溶胶通量双通道分析仪，该分析仪的电磁辐射波长分别为λ = 0.65和3.4 μm，测速τ≤0.05 s，数字化数据可通过RS-485接口传输至1200 m外的服务器。介绍了其设计及在检测直径为0.2 ~ 5000 μm、光密度D≤3.5的粒子流过程中的特点。结果表明，基于辐射散射理论计算的λ = 0.65和3.4 μm的波衰减系数与液滴尺寸之比与实验结果一致。所创建的气溶胶分析仪可用于燃料液体的技术性空气排放的快速分析，以及在大气中精细分散的气溶胶云产生脉冲屏障时用于开发爆炸性大型发电机。
