Dry fog dust suppression in material handling production line
Dust generation has long been a problem in the transport systems of ore, sintered raw materials, coal fuel and other materials in iron and steel smelters, and national regulations have been introduced to control dust. To solve the dust problem, many different dust control methods and equipment have been put into use, such as: electric dedusting, wet electric dedusting, water mist dedusting, spray dedusting, bag dedusting, negative pressure dedusting, etc.
In recent years, the application of dry fog dust suppression has emerged in consideration of equipment input, usage costs and the impact of travel methods on the site environment. Mechanical equipment type dust removal, because of the equipment operation costs, high energy consumption, and a large area, can not be used in some special space, and water fog / spray dust removal will be due to the large amount of water caused by the waste of water resources and lead to a dirty site environment, so the advantages of dry fog dust suppression gradually revealed, and in recent years a lot of use.
Dry fog dust suppression, mainly through a special air atomizing spray nozzle, a collection of multiple nozzles used together to produce ultra-fine water mist particles within 30μm, using the diffusion characteristics of the droplets, so that the fine dust generated in the material transport combined with the water mist particles, so that they fall by gravity in order to collect, to prevent the spread of fine dust into the air.
For certain applications where dry fog fugitive distances are required, multiple nozzles are integrated into one or more spray manifolds to take advantage of the combination of water mist with a longer range to achieve increased spray distances.
