| description | The invention relates to an internally-wound and externally-folded composite large-area high pollutant-holding capacity large-thick filter core. The diameter of a conventional filter core framework isonly 68mm, the space between an inner framework and an outer framework is small, can hardly accommodate a filter membrane with large thickness, and also is insufficient to accommodate filter membranecombinations of different specifications, thus resulting in weak interception and pollutant-holding capacity overall and defects. The filter core is characterized by comprising a large-thick framework with a diameter of 128-134mm, the large-thick framework comprises an inner framework and an outer framework, and an inner winding filter membrane and an outer folding filter membrane are sequentially arranged between the inner framework and the outer framework. The inner filter membrane is wound by 10 layers, the fold height of the folding filter membrane is 14mm, and the number of times of folding is 120. According to t |
