[Abstract]:Objective: Through the investigation of the possible occupational hazard factors in the denitrification process system of the coal-fired power plant, the types and main links of the occupational disease hazard factors that may be produced in the project are analyzed and clarified. By detecting the concentration or intensity of the main chemical and physical occupational hazards in the project, and evaluating the main occupational hazard factors in the project, To ensure that the project creates a working environment and conditions that meet the national occupational health standards and health requirements, and to take measures to ensure workers' access to occupational health protection. Methods: 1. The contents of the on-site investigation of occupational hygiene include: the production process of the project, the identification and determination of the types of occupational disease hazard factors existing in the production, the verification of the occupational disease hazard protection facilities in the workplace, and the emergency rescue facilities, Personal use of occupational disease protection equipment, occupational hazards warning signs and other measures to implement the situation. 2. In accordance with the requirements of the relevant national technical specifications and standards, under the normal operation of the project, the occupational hazard factors produced in the production process are detected on the spot and analyzed in the laboratory. The intensity (intensity) of occupational hazard factors and the protective effect of occupational hazards protection facilities in the workplace of the project were evaluated. Results: 1. The results of the occupational health field investigation show that the main hazard factors of the denitrification system in this power plant are COCOC _ (2) no _ (x) so _ (2) NH _ (3), furnace dust, noise and high temperature. 2. Under the normal operation of the project, the results of on-site sampling and detection of the COCOC _ 2NOX _ XO _ 2NH _ 3 in the air of the workplace show that the COCOCO2NOxso _ 2o _ 2 / NH _ 3 in the air of the workplace is in line with the national occupational health standard limit for the short time contact concentration of the furnace dust. The results show that the number of COCOO _ 2O _ x so _ 2 / NH _ 3 in the air of the workplace is in accordance with the national occupational health standard. The noise intensity of the dilute fan in the working place exceeds the national occupational health standard, and the noise intensity in other workplaces conforms to the national occupational health standard limit. 3. Occupational disease prevention measures, the workplace with more complete personal protective equipment and emergency rescue measures. Workplace has occupational safety warning signs, but ammonia irrigation areas and other toxic gases without warning signs. Conclusion: 1. In the denitrification system of the power plant, there are main hazard factors of occupational disease, such as COCO2CO2NOSXSO2C, NH3SO2S, NH3V2O5, furnace dust, noise and high temperature. Among them, NH3 / V2O5, dust and noise are the key control points of occupational disease hazard in denitrification process. 2. The project has taken necessary measures to prevent and control occupational diseases.
