Choice of three different levels of dust removal equipment : the first choice is dust prevention, that is, like various diseases, prevention is always more cost-effective than treatment. For example, adding a flow slot when loading and unloading materials and belt transfer can greatly reduce dust or smoke. Production and processing capacity; when processing loose materials such as steel slag, local sealing is adopted to allow the generated dust and soot to circulate and consume its kinetic energy, and most of the dust will settle naturally. This type of mechanical dust prevention and dust removal is called unpowered dust removal in foreign countries. In most cases, most of the dust is suitable for unpowered dust removal; at least first, unpowered dust removal pretreatment is required.
Choice of three different levels of dust removal equipment , followed by auxiliary use of water spray mist or foam dust removal. On the one hand, direct spray can make the dust particles adhere to each other, condense, grow up, and then be easily separated from the atmosphere. On the other hand, for relatively high temperature flue gas, direct spray can be used to achieve evaporative cooling. Flue gas cooling, volume shrinkage, and reduced speed are also conducive to dust removal. In the past, textbooks and design manuals stated that spray dust removal is only suitable for handling dust over 50m, and the dust removal efficiency is only 40-70%. Practical experience proves that due to the advancement of spraying technology, dust can be removed by spray systems with a length of more than 10m, which is close to 100%, and dust with a length of more than 1m can also remove 90-95%. For example, the use of spray dust removal for tundish turning and steel slag treatment has actually achieved a high dust removal efficiency of 90-95%. Therefore, from the perspective of reducing emissions, saving energy and reducing costs, we must first consider unpowered dust removal and direct spray dust removal.
The choice of three different levels of dust removal equipment is really a last resort before considering the third option: ventilation and dust removal. Because as long as you choose ventilation and dust removal, you must have high energy-consuming fans and dust collectors, it is more difficult to save energy and reduce costs.
When using a ventilation and dust removal system, we must first consider electric dust removal with low energy consumption, and finally consider a bag dust collector. According to this thinking, reflecting on the actual order of our current dust removal equipment, we can find some problems worth improving: such as converter secondary dust removal, blast furnace iron field dust removal, loading and unloading dust removal and many other similar applications, dust particles 80%, even 90% The above are more than 10m, but almost all of our country adopts ventilation dust removal and bag dust collectors, which solves the problem of reducing emissions, but the operating costs are very high; when the LT method of the converter is used, the dust is also the majority. It is coarse particles, but the inlet concentration of electrostatic precipitator is designed according to 70-100 g / m3, resulting in many electric fields and huge equipment. Of course, the unstable efficiency of some electrostatic precipitators is also a practical problem that must be solved. Cloth bag dust collectors are commonly used in today's society for dust removal and environmental protection products. Their efficient dust removal rate makes them favored by industrial production. However, sometimes the dust bag of the dust collector will age. The cause of this aging phenomenon is not entirely due to the dust bag. After using for a long time, sometimes the influence of working conditions will also cause the aging of the bag of the dust collector, so pay more attention when using to prevent aging.
