A laser sensing inverse task solution method without using of integral equations has been suggested in this paper and it can
be used for aerosol particles’ sizes and concentration monitoring equipment creation for the real practice of the industrial
production. This method is based on the laser radiation intensity weakening at a limited set of the probing laser radiation
wavelengths. The computer simulation of aerosol flow parameters has been fulfilled and its results showed that during the
regular operation of enterprise’s dust cleaner equipment at the certain point of the technological process the aerosol can
be described by a function of particles distribution by sizes, and this function depends on finite number of parameters. The
particles’ sizes distribution function is described by the logarithmic normal law after a fabric filter as a last step of the dust
cleaner equipment. The laboratory setup realizing the laser sensing at the several laser radiation wavelengths possibilities
simultaneously by the spectral transparency and integral light scattering methods for investigation of studied aerosol
flows’ optical parameters dependence has been created. A complex refractive index of the studied substance has been
investigated. The dependence between the logarithmic normal distribution function parameters and the average volume
- surface diameter values received as a result of the sensing has been revealed. The suggested method of the inverse task
solution can be developed for the dust gas cleaning equipment refusals detection.
The article develops a new approach to the enhancement of ecological safety and productivity of dust-trapping and gascleaning
units; technique is based on modified spectral clarity method. Dusted airflow was studied on special dust-test bed
with modified spectral clarity method. Research is based on implementing three-wavelength lasers for discovering not only
mass concentration of dust, but its size-consist determination. It allows constructing a sensor able to detect faults of sock
filters in real-time on early stages.
Industrial aerodisperse flows were characterized by significant aerosol polydisperse and concentration level. Thus particle concentration and size distribution have the information about the corresponding technological process condition. The aerosol parameters studies in the different places of the aerodisperse flow allows us to fulfill the optimal monitoring method choosing of these parameters in real time for the cement production. The particle size spectrum transformation analysis in the aerodynamic qualifiers in the real industrial flow of the cement aerosol particles has shown the opportunity of the aerosol dispersive control in the real time by the spectral transparency at the number of the wavelengths method.
