Environmental protection industry in China started relatively late already, but also in the early stages of development also did not receive due attention, only relatively fast development in recent years and some domestic small dust does exist some problems, such as manufacturing process unreasonable, or the operation is not standardized type, using the occasion more special cause dust can not be used; in addition, bag filter temperature control and regulation measures has been design challenges, making dust condensation neither prevent hypothermia, and not prevent high temperature "burn bag." This is the long-standing problems plagued many enterprises, affecting the normal production of cement enterprises. Objectively speaking of small dust removal equipment and other products, although some gaps, product performance is not very stable, poor adaptability in terms of quality, technology, compared with foreign countries for pollution but with increased determination, enacted The relevant standards are more meticulous grid, all companies use foreign dedusting equipment is unrealistic, so our production of small dust of enterprises will have a bigger market, while the corresponding competition will intensify, which is China's removal equipment www .sdlqhbsb development has also played a positive role in promoting. So, to say dust removal equipment and environmental protection is a very important link.
