Person working environment occupational safety and health index system simulation test bench

Abstract

The invention discloses a person working environment occupational safety and health index system simulation test bench, which comprises main parts such as a person respiration simulation system, a working environment simulation cabin body, a spraying system, an air flow rectifier, a dampening machine, a floor air conditioner, an exhausting fan, a particulate sampler, a particulate generator, a data analysis system and a Malvern laser particle size analyzer. The exhausting fan and the air flow rectifier placed in the simulation cabin body are used for simulating the operation air flow field, the spraying system is placed in the simulation cabin body, and spraying under certain pressure is thus realized; and the particulate generator, the dampening machine and the floor air conditioner are placed at the free end of an air inlet of the simulation cabin body to simulate the environment and the micro climate of working particulates, and parameters such as the particulate inhalation condition by a working person and the particulate concentration are measured through the person respiration simulation system and the particulate sampler. Thus a reliable technical support is provided for research on the person working environment occupational safety and health index system.

Description

technical field [0001] The invention relates to a simulation experiment device, in particular to a simulation test experiment platform for an occupational safety and health index system of a personnel working environment. Background technique [0002] With the progress of society and the improvement of living standards, all walks of life pay more attention to occupational diseases. Among them, pneumoconiosis has gradually become the focus of increasing attention. On December 3, 2015, the National Health and Family Planning Commission released the "2014 National Occupational Disease Reporting Situation". According to statistics, a total of 26,873 new cases of occupational pneumoconiosis were reported, an increase of 3,721 cases compared with 2013. Among them, 94.21% of the cases were coal workers' pneumoconiosis and silicosis, 13846 cases and 11471 cases respectively. The reported cases of pneumoconiosis accounted for 89.66% of the total reported cases of occupational disea...

Problems solved by technology

Dangerous substances that cause occupational diseases include: dust, toxic gases, high temperature noise and other physical factors and radioactive factors, etc. A large number of occupational disease patients will spend a lot of manpower, material and financial resources on treatment, not only the economic loss is huge, It also brings great pain to patients and their families.

[0004] It can be seen that the high-concentration particles, high-temperature noise, toxic gases and other hazards in the production site have a great impact on the health of the workers, causing many workers to suffer from pneumoconiosis, skin infections, tinnitus and other organ damage, and even chemical poisoning Died without being cured in time

However, the operating environments of all walks of life are relatively complex and diverse, which has caused great difficulties for domestic and foreign experts to conduct in-depth research on operating risk factors, and domestic and foreign experimental simulation devices for personnel operating environments have not yet appeared.
