Powder (coal) dust, one of the five natural disasters in coal mines, has always been the focus of prevention and control in the coal industry. Over the years, the state has invested a great deal of manpower, financial resources, and material resources in reducing and controlling dust hazards and preventing the occurrence of pneumoconiosis, and has achieved significant results.

The coal transportation specialty of the Combustion Department of Houma Thermal Power Branch is the most exposed to coal dust. Precipitator and water flushing are effective control measures for comprehensive management. Before each class gets coal, the dust remover must be started. The belt inspectors come to their respective jurisdictions in advance. First, open the dust collector water, water distribution, adjustment, and then start. After the belt is started, the coal is put on, and the dust remover will play a role. The dust collector of the fuel transport department is generally installed at each of the blanking and transfer stations. The dust thus generated is sucked into the pipe by the dust collector, passes through the water inside the dust collector, and is atomized by the water distribution door to match the water and the powder. Fall into the bucket to precipitate, outflow from the outlet, the filtered static air discharged to the atmosphere dust removal efficiency of 99.8%. In combination with timed water flushing, the working environment is purified and controlled.

Everyone knows that the harm of dust on the human body is very large. I will introduce to you in this simple matter the damage caused by dust to the body. If soluble toxic dust enters the respiratory tract, it is quickly absorbed into the bloodstream and causes poisoning; radioactive dust can cause radiation damage; some hard dust can damage the cornea and conjunctiva, causing corneal opacity and conjunctivitis; dust blocking the sebaceous glands When mechanically irritating the skin, it can cause acne, folliculitis, pyoderma, and the like; the most harmful effects of dust on the body are respiratory damage, including upper respiratory inflammation, pneumonia, lung cancer, pneumoconiosis, and other occupational lung diseases.

So, ah, the first day we went to work, the leaders told us that we should properly wear safety helmets, dust masks and other protective equipment, properly operate the dust removal equipment, ensure that the monitoring water is flushed, be familiar with safety and health knowledge, and improve the safety level. While maintaining the harmonious and stable development of the enterprise, we must do our own protection.
