Several Common Cement Dryer Filters

Cement dryer is a kind of device that materiel can be dried by heating in it. Helical blade and indirect rotary lifting plate is arranged inside the inner and the outer cylinder, smoke tube, annular flue gas pipe and smoke outside cover device are also installed in the cylinder.
Drying equipment for cement plant using are general rotary dryer, vertical dryer, suspension dryers, flow dryers, the most popular of which is rotary dryer. The materials needed to be dried in the cement plant are clay, shale, slag, steel slag, coal, etc. Characteristics of waste gas produced by drying of different materials are different. Dryer exhaust gas needs to be highly efficient dust removal equipment to discharge standards. The common cement dryer filters are cyclone dust collector, electrostatic precipitators, bag filter.
Cyclone dust collector
The cyclone dust collector can adapt to the change of the exhaust gas composition of the cement dryer and is especially suitable for the high humidity content of the dryer. In addition, the cyclone dust collector covers small area, system investment is low and maintenance is more convenient. The cyclone dust collector is mainly applied in the cement plant dryers dust removal system in the past. However, the efficiency of the cyclone dust collector is not high and also excessive emissions, so it can not meet the current environmental requirements。
Electrostatic precipitator
As an efficient dust collector, electric dust collectoris is widely used in many kinds of cement dryers. But the humidity of the dryer waste gas is higher, which not only affects the electric precipitator effect but also to the electric dust collector corrosion and ultimately affect the normal role of electrostatic precipitators. This is also the reason why electrostatic precipitator is limited.
Bag filte
In the early design of the dryer waste gas dust removal system, the long-term use of bag filter is limited. On the one hand, the system must be set cyclone dust collector due to the limitation of the old bag precipitator performance, which not only cause a large quantity of air leakage but also the energy consumption is too large, On the other hand, because of the special nature of the drying machine, there are many problems in the process of using the bag filter, which can not be used for a long time. With the continuous development of the bag filter technology, especially the development and application of the new filter material and the development of the cleaning technology, the bag filter has been widely used in the cement dryer。
