Description

Automatic dustproof dust fall system

Technical Field

The utility model relates to a dust removal dust fall field, in particular to automatic dust suppression system prevents dust.

Background

Coal is the main energy in China at present, occupies an important position in national economic energy structures, and accounts for more than 76% of primary energy consumption in China. Along with the rapid development of national economy, the demand of coal is more and more large, in recent years, the yield of raw coal is rapidly increased, and along with the expansion of production scale, the coal dust pollution condition is more and more serious.

Coal dust belongs to dust, is generated in the links of coal mining, stockpiling, transportation, processing and utilization and the like, and forms one of main pollution sources of gas-phase factors in operation places. In the coal industry, almost all operations generate dust during coal production. Along with the increase of the mechanization degree of coal production and the continuous improvement of coal mining strength, the coal dust generation amount of each operation section such as rock drilling, blasting, loading and unloading, crushing, transportation and the like is greatly increased. Under the condition of no dustproof measures, the dust concentration of the blasting mining working face can reach 300-500mg/m3, the dust concentration of the mechanical mining working face can reach 1000-3000mg/m3, and the dust concentration of the fully mechanized mining working face can reach 4000-8000mg/m 3. Seriously pollutes the environment of the workplace, harms the physical health of workers and influences the safe production.

In China, pneumoconiosis is one of the major occupational diseases. With the acceleration of the reform and opening pace in recent years and the rapid development of economy, the social demand for energy and industrial and mineral products is increased, and the influence caused by dust disasters is gradually expanded. And the coal dust is explosive and suspended in the air to reach a certain concentration, and the coal dust can explode if a heat source capable of igniting the coal dust exists. Coal dust explosion can cause serious accidents such as coal mine extra-large gas explosion. In coal mines, the consequences of coal dust explosion are more serious than gas explosion, and the former will generate a large amount of asphyxiating gas carbon dioxide and toxic gas carbon monoxide to cause the poisoning or death of miners; the latter mainly produces water vapor and carbon dioxide gas. Therefore, the method is particularly important for treating coal mine dust.
