Simulation system and industrial and mining environment dust simulation method

Abstract

The invention discloses a simulation system used for safety and health of industrial and mining environment dust occupational diseases and an industrial and mining environment dust simulation method. The simulation system and the simulation method can realize simulation of an industrial and mining dust environment; simulation of each influence factor of an operating environment is realized by virtue of an axial flow fan, a dust emitter, a noise simulator, a temperature regulator, an air pressure controller and a humidity regulator mainly; determination analysis of each influence factor in the environment is realized by virtue of a dust sampler, a temperature sensor, a humidity sensor, an oxygen content sensor, an atmosphere sensor, a toxic and harmful gas sensor, an air speed sensor and the like; finally two analysis methods that a human respiratory organ simulator is used for simulating human respiration and organs of a mouse are used for damaging the simulation are utilized for analyzing health condition of personnel in factors and under conditions of different dust environments, temperatures and humidities, ambient pressures, oxygen contents and the like, a damage mechanism of respirable dust in the industrial and mining dust environment on a human respiratory system and deposition law of the respirable dust can be obtained by combining with animal anatomy, and finally a dust pathogenic mechanism 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
