It is well known that a small amount of lubricating oil will fall off during the cooling process of the rolling mill. In addition, a certain amount of steam will be generated during the cooling process of the rolling mill. The main components of dust are iron oxide, iron oxide, water and oil fume. At the same time, dust contains a lot of liquid components such as water and oil, which is viscous, humid and delicate.
At present, in the dust removal equipment used to deal with dust in rolling mill, the pulse bag filter is very easy to block the filter bag due to oil and water in the dust. As the dust contains oil and water, the dust adhesion increases, and the collection effect of dry electrostatic precipitator decreases sharply; Due to the poor adaptability of wet electrostatic precipitator to dust, the changes of dust content, particle size and specific resistance in flue gas will change its dust removal efficiency, resulting in unstable exhaust gas concentration. At the same time, the dust removal process of rolling mill has not been well applied due to the limitation of site; Cyclone dust removal equipment can not be selected due to poor dust removal effect, large volume and other factors; The wet dust collector covers a large area, the sewage treatment system is huge, and the treatment effect is unstable, resulting in the unstable discharge concentration after dust removal and purification of the rolling mill, which can not be well promoted.
The plastic plate burning dust remover used for dust removal of rolling mill is a new generation of ultra-high efficiency dust remover developed and produced abroad nearly 20 years ago μ M, the collection efficiency is up to 99.9%, and the emission concentration is less than 5mg / m3. Because the plastic plate burning dust collector adopts unique plastic plate burning filter accessories, the plate is acid-base resistant, wear-resistant and moisture-resistant, and its general service life is more than 10 years. At the same time, the overall structure of plastic burning plate is compact, the layout between plates is reasonable, and the overall volume is about 1 / 3 ~ 1 / 6 of that of bag type dust collector. The special structure and surface morphology of plastic burning plate dust collector can greatly reduce the floor area of dust removal equipment.
