What are the effects of the pulse cleaning method on the dust bag?
1. choose low-voltage pulse cleaning. The glass fiber in the glass coated dust bag has the characteristics of no folding and no wear resistance, and it is generally not used for pulse ash cleaning. Since the selection of glass fiber coated composite filter material, because the surface filtration cleaning is easy, the resistance is not easy to rise, the cleaning cycle is also lengthened. However, the internal glass fiber base cloth, due to the use of external filter filtration, glass fiber cloth has a skeleton, so the relative movement between the bag and the skeleton will produce wear, coupled with frequent blowing ash, the contact between the dust bag and the skeleton is close, and the amplitude change with the spacing and zigzag changes directly affect the life of the dust bag. In addition, when the pulse air blows the dust bag, the higher pressure air in the bag makes the bag in the shrinking state expand rapidly, the bag will produce the dislocation between the fibers under the action of high pressure, the greater the pressure, the greater the friction of the dislocation contact surface, the shorter the life of the dust bag. Therefore, under the premise of not affecting the cleaning effect, reducing the cleaning pressure is also an aspect of extending the life of the dust bag. When the glass fiber coated dust bag is used, the low pressure pulse ash cleaning comes into being.
2.offline cleaning wind speed is higher than the online cleaning wind speed, cleaning is easy, and can use lower pressure, to save energy, especially for glass fiber coating, should be used offline cleaning, to extend its life.
