As one of the five natural disasters in coal mine, coal dust has always been the focus of prevention and control work in coal industry. Over the years, the state has invested a lot of human, financial and material resources in reducing and controlling dust hazards and preventing the occurrence of pneumoconiosis, and has achieved remarkable results
the coal handling specialty of the combustion and Chemical Department of Houma thermal power company is the most exposed to coal dust. Dust collector and water flushing are effective control means for comprehensive treatment. Before each shift starts coal, the dust catcher must be started. The belt inspectors come to their respective positions in advance, first turn on the water supply, water distribution, adjustment of the dust catcher, and then start it. After the belt starts, the coal is loaded. At this time, the dust collector plays a role. The dust remover of the fuel transportation department is generally installed in each blanking transfer station. The dust generated in this way is sucked into the pipeline by the dust remover. The water inside the dust remover is atomized through the water distribution valve, and the water and powder are mixed together. They fall into the water bucket for precipitation and flow out from the water outlet. The filtered still air is discharged to the atmosphere, and the dust removal efficiency reaches 99.8%. Combined with regular water cleaning, the working environment is purified and controlled
as you all know, dust is very harmful to human body. Here 1 will briefly introduce various kinds of harm caused by dust to human body. Such as soluble toxic dust into the respiratory tract, quickly absorbed into the bloodstream, causing poisoning; Radioactive dust can cause radioactive damage; Some hard dust can damage cornea and conjunctiva, cause corneal opacity and conjunctivitis; Dust blocking sebaceous glands and mechanical skin irritation can cause acne, folliculitis, pyoderma and so on; The greatest impact of dust on the body is respiratory system damage, including upper respiratory inflammation, pneumonia, lung cancer, pneumoconiosis and other occupational lung diseases
so, on the first day of our work, the leaders told us to correctly wear safety helmets, dust masks and other protective equipment, correctly operate dust removal equipment, monitor water flushing safety in place, be familiar with safety and health knowledge, improve safety level, and do a good job in self-protection while promoting the harmonious and stable development of the enterprise
