Simulation system and dust simulation method in industrial and mining environment

Abstract

The invention discloses a simulation system for industrial and mining environment dust occupational disease safety and health and an industrial and mining environment dust simulation method, which can realize the simulation of industrial and mining dust environment, mainly through axial flow fans, dust emitters, noise simulators, temperature Regulators, air pressure regulators, humidity regulators, etc. realize the simulation of various influencing factors of the working environment, and realize monitoring through dust samplers, temperature sensors, humidity sensors, oxygen content sensors, atmospheric pressure sensors, toxic and harmful gas sensors, and wind speed sensors. The measurement and analysis of various influencing factors in the environment, and finally use the human respiratory organ simulator to simulate human respiration and mouse organ damage simulation two analysis methods, to test the personnel under different dust environment, temperature and humidity, ambient air pressure, oxygen content and other factors Based on the analysis of health status, combined with animal anatomy, the damage mechanism and deposition law of inhalable dust in the industrial and mining environment on the human respiratory system are obtained, and finally the pathogenic mechanism of dust is revealed.

Description

technical field [0001] The invention relates to a simulation system for industrial and mining environment dust occupational disease safety and health and a simulation method for industrial and mining environment dust. Background technique [0002] Industrial and mining production dust hazards are very common. Dust hazards exist in both developed and developing countries. Nearly hundreds of millions of workers in the world are exposed to dust. The physical and mental health of workers who have been exposed to dust for a long time will be seriously threatened. According to the data released by the National Health and Family Planning Commission, there are more than 20,000 new cases of pneumoconiosis in the country every year. Among them, the coal industry reports pneumoconiosis (coal worker pneumoconiosis and silicosis) It accounts for more than 50% of the number of occupational cases reported nationwide. According to incomplete statistics, since the founding of the People's R...

Problems solved by technology

[0003] The complex production process, high degree of mechanization, and many dust sources in the industrial and mining environment make the dust removal effect of the existing dust removal technology and equipment unsatisfactory

However, the research and development of dust removal technology and equipment has been slow at present. The main reasons are as follows: (1) The pathogenic mechanism of respirable dust is relatively vague; (2) The influence of multiple environmental factors on the inhalation of dust is not clear; (3) Insufficient understanding of the main controlling factors of dust physical and chemical characteristics that damage the occupational health of personnel, and there are few experimental methods for dynamic simulation of industrial and mining environments at home and abroad
