Different options for dust removal equipment

1. It is dust-proof and dust-removing equipment used to dispose of slags such as steel slag. Partially closed, so that the generated dust, dust and dust circulate in it to consume its kinetic energy, the dust will naturally settle down in large part. This type of mechanical dust-removing and dust-removing is known as unpowered dust-removing in foreign countries, and most of the dust in large areas is suitable for non-dust-removing dust; at least, non-power dust-removing pre-treatment is required.

2, is the auxiliary use of spray mist, or foam dust. On the one hand, direct spray can make dust particles wet, adhere to each other, agglomerate and grow, and then easily separate from the atmosphere. On the other hand, with respect to the flue gas with a relatively high temperature, the direct spray completes evaporative cooling and can be made with a small amount of water. Flue gas cooling, volume shrinkage, and speed reduction also contribute to dust removal. Past textbooks and design manuals say that spray dusting is only suitable for handling dust of more than 50um, and dust removal efficiency is only 40-70%. The theoretical experience has proved that due to the advancement of spray technology, after the spray system can remove more than 10um of dust close to 100%, more than 1um of dust can also remove 90-95%. For example, the tundish and steel slag disposal and spray dedusting have reached a high dust removal efficiency of 90-95%.

3, ventilation and dust removal. Because only need to choose the ventilation dust removal, must have the high energy consumption fan and the dust collector, the energy conservation reduces the capital to be difficult. Ventilation and dust removal systems mainly include electrostatic precipitators and bag dust collectors. Bag filter dust collectors, with the increase of environmental protection requirements, electrostatic precipitators can not meet the current environmental protection requirements, bag filter is the latest application.
