The utility model has the following beneficial effects:
1. the supply period is short. The modular corrugated filter plate has unique size, can be used for batch stock, can stack the number of modules according to the size of a used project, and does not need design and processing period.
2. The service life is long. The modular pleated filter plate is made of stainless steel and matched with a high-performance pleated filter material. Compared with the conventional cloth bag, the cloth bag avoids the abrasion between the cloth bag and the bag cage; compared with the conventional filter cylinder, the defect that the folded filter cloth expands outwards and cannot be restored due to failure of the limiting binding band is overcome. The normal service life of the device can reach 8-10 years.
3. The overall investment is small. The modular folded filter plate is 4-6 times of the filtering area of a conventional cloth bag with the same size. Compared with the conventional bag-type dust remover, the matched dust remover has the same treatment capacity and the volume of 1/4-1/3, so that the equipment cost, the occupied space and the operation and maintenance cost of the whole project are greatly reduced.
The utility model relates to a novel modularized folded filter plate which is compact in arrangement mode, and compared with a dust removal cloth bag, the size of a filter area is increased by 4-6 times. The matched dust remover has small floor area and compact designThe unit assembled box body greatly reduces the space occupied by the equipment, and the volume of the unit assembled box body is 1/4-1/3 of a conventional bag-type dust collector. According to the needs of the working conditions, the filtering material of the pleated filter plate can be made of any material, and is suitable for working conditions with different temperatures and different characteristics. Meanwhile, the stable resistance-PTFE film advanced manufacturing technology is adopted, so that the surface filtration is realized in the dust removal process, and the dust removal can reach 5mg/Nm3Ultra clean emissions are as follows. The resistance of the device does not change along with the change of the ash cleaning process and the dust attachment degree in the operation process, the resistance is constant, and the operation cost of the facility is reduced.
