Correlation Study Of Occupational Diseases Of Respiratory System Based On Haze Dynamics Numerical Simulation

With the deterioration of air quality,the phenomenon of haze weather has increased,and the harm has increased.Air pollutants can cause different degrees of damage to the respiratory system of the body,and can cause occupational diseases such as allergic pneumonia,asthma,and chronic obstructive pulmonary disease.The main work of this paper is as follows:Establish and develop aerosol particle dynamics model in haze environment,apply the multiple Monte Carlo method to solve the zero-dimensional particle group equilibrium simulation equation(PBE equation),and carry out single effect of aerosol particles in haze environment(Condensation,fragmentation,nucleation,deposition,condensation /evaporation,chemical reaction,etc.)mechanical properties,and the effect of humidity on smog.Due to its large specific surface area,small particle size particles can absorb relatively many toxic substances.Small particle size particles inhaled through the respiratory tract can induce occupational diseases such as asthma,chronic obstructive pulmonary disease and other respiratory infections.Particulate matter concentration and scale distribution characteristics,and further study the distribution characteristics of small particle size in haze days,to analyze the correlation between the particulate matter concentration and the number of outpatients of occupational diseases of respiratory tract infections.This paper will use Fortran software to carry out numerical simulation experiments on existing theoretical solutions and data,and then analyze the trajectory,number and concentration of particles in the fog layer,and the space-time distribution of the average size of the particles,and discuss the effects of aerosols and droplets.The number and particle size factors,and on the basis of this analysis of the correlation between the dynamic events of haze and respiratory infections.
