Unorganized emission of pollution by industrial and mining enterprises refers to the lack of organization and standardization of pollutants discharged by industrial and mining enterprises, resulting in the direct release of pollutants into the atmosphere, water bodies or soil, which has a negative impact on the environment and human health.
In order to strictly control the unorganized emissions of enterprises, enterprises should start from the production process, strengthen technological transformation, reduce the amount and concentration of pollutants discharged, and achieve sustainable development. The specific methods and means are as follows:
1. Control of unorganized discharge of lumpy materials
For the block materials of the enterprise, they can be stored by means of shedding and warehousing or the construction of windproof dust suppression nets, and comprehensive dust control measures such as sprinkling, spraying, and cover can be used for dust suppression.
2. Control of fugitive discharge of powder and granular materials
For coal, coal gangue, cinder, coal ash, cement, lime, gypsum, sand and other powdery and granular materials and fuels that are easy to produce dust, they should be stored in a closed manner, and the transportation should be carried out in a closed belt, closed corridor, tubular belt conveyor or closed carriage, vacuum tanker, pneumatic conveying and other closed transportation methods.
3. Control of unorganized emissions from material loading and unloading transportation
Automobiles, trains, belt conveyors and other unloading points are provided with gas collection hoods or airtight covers, and equipped with dry fog dust suppression systems, bag dust removal and other treatment equipment, the road surface of the material yard should be hardened, and the exit is equipped with wheel and body washing devices, etc., to comprehensively control the unorganized emissions of enterprises.
4. Control of fugitive emissions in the production process
For the dust production point (device) in the production process of the enterprise, it should be covered and closed, set up a gas collection hood and equipped with relevant dust removal facilities, and the workshop should not have visible smoke and dust exposed.
In addition to fugitive emission control, enterprises should also establish a comprehensive monitoring system, including first-class monitoring equipment and regular sampling monitoring, to monitor the discharge of major pollutants in real time.
The integrated platform for the control and control of unorganized emissions is a set of centralized control platforms, which can monitor the organized and unorganized emission sources in the enterprise plant in real time, systematically accurately determine the location of dust production points, and intelligently start and stop dust control facilities, and can also set up work plans to control the start and stop of treatment equipment, so as to realize the automatic control and governance of unorganized emissions, and help enterprises improve the overall governance efficiency and reduce the difficulty of control.
