As we all know, cartridge filter and bag filters are efficient dry dust removal equipment, has a high collection efficiency, stable operation, less wearing parts, etc., so it is widely used in industrial and mining enterprises. However, cartridge filter and bag filter are also some differences in the difference it where? Now let us cite two aspects make you look! A, the difference between the filter material and on the principle a, cartridge or bag filter was hard folding a cylindrical arrangement, skeleton, short, between cylinder spacing, thorough cleaning, no secondary pollution. b, filter bag with soft sewn into a bag, set into the steel welded into a skeleton (commonly known as dragon skeleton), kin to bag clouds, media types and long polyester fiber material treated more as a single layer general industrial polyester cloth. c, filtration principle surface filtration principle: no cartridge filter dust deep within the media depth filtration principle. Bag filter dust deep within the media, by the establishment of the outer surface of the filter layer of dust collection efficiency maintenance. B, advantages and disadvantages ①, cartridge filter advantages: THREE NEW: New Media: waterproof wear corrosion, the new structure of the hard folding filter arrangement, no steel skeleton, no media wear and tear, the new theory: instead of deep filter surface of the filter dust, no penetration and internal filter. Cleaning formula used for years, behind the air box pulse dust blowing, mechanical rapping crew, have already been eliminated in Europe and America and other countries. It is these old cartridge filter dust generation product, its advantages are as follows: a) the surface of the filter cartridge filter collection efficiency is much higher than the old filter, greatly reducing the emissions of harmful substances, air purification index reached the world advanced level, completely changed the backward state of the old dust is mainly the . b) filter cartridge filter without wear and tear, the body which has no moving parts, long-term use is not required to repair (even removable cartridge is also very convenient) to avoid the old-fashioned dust constantly changing media trouble, save money time-saving nor secondary pollution. c) cartridge filter its size, weight is far less than the old filter with the specifications, save construction space and civil load, saving significant infrastructure investment. d) cartridge filter resistance is small, a small amount of compressed air consumption, no maintenance workload. Various types of dust than the old energy, owned more than 30%, any enterprise can not ignore the energy savings to the enterprise significant economic benefits. ②, bag filter of the advantages: a) It is simple, continuous cleaning, resistance stability, high filtration speed, no internal moving parts, simple design and other characteristics, is a high performance bag filter. b) high dust removal efficiency, capture 0.3UM above the dust, so dusty gas purification to 15mg / m3 or less c) less ancillary equipment, investment, technical requirements are not high ESP. d) can capture ESP dust is difficult to recover, and to some extent, nitrites, sulfides and other compounds can be collected. e) adaptability to changes in load, especially suitable trapping fine dry dust, collect dry dust to facilitate the handling and recycling. f) collecting baghouse containing explosive or dusty gas with a spark higher security. ③, bag filter disadvantages: a) for different types of gas, you should use the appropriate type of bag, and the need for frequent replacement bag, bag consumption is large. B) When collecting dust gas high humidity, moisture should take measures so as to avoid condensation caused by “paste bag”, so baghouse gas humidity have certain requirements. c) greater resistance, general pressure loss 1000-1500PA. d) For the high-temperature gas, cooling measures must be used. E) When receiving a large particle diameter of dusty gas, bag easier to wear.
