1. Excuse me, the body position of the filter bag is worn, from the inside to the outside of the vertical strip wear marks in the middle of the filter bag, and the damage is at the contact of the vertical ribs of the bag cage. How to deal with this situation?
If the damage marks are from the inside to the outside, and the damage is in the contact of the vertical ribs of the bag cage, it means that the vertical ribs of the bag cage are unsoldered or rusted. Folding and breaking at the contact position causes damage. This type of wear problem can be solved by replacing the bag cage or adjusting the blowing device.
2. If the damage marks are from the outside to the inside, and the damage is at the contact of the vertical ribs of the bag cage, how to solve it?
If the damage marks are from the outside to the inside, the damage is at the contact point of the vertical ribs of the bag cage. There are often traces of friction with the filter bag on the outside of the filter bag (adjacent filter bag or box member). This kind of wear is caused by the deformation of the bag cage or the installation of the filter bag is too small, the diameter of the filter bag is too large or loose, which causes the contact between the filter bag and the filter bag, the filter bag and the dust collector box member, and the filter bag is damaged during the blowback process. Expansion rubs against each other to wear.
Generally, the bag cage needs to be replaced and the installation quality is guaranteed. In the design process of the bag filter, the distance between the filter bag and the distance between the filter bag and the box structure should be avoided too small.
3. What kind of dust removal equipment should be used to deal with high dust concentration gas?
To process gas with high dust concentration, cyclone dust collector or gravity dust collector is generally installed for pre-dust removal. At the same time, the resistance of the system must be increased and the power consumption will increase. Therefore, when the dust or finished materials do not need to be classified, the bag filter is mostly used directly.
However, it should be noted that not all bag filters can handle gases with high dust concentrations.
Only a bag filter that meets two points is suitable for processing gas with high dust concentration.
One is that the distance between the filter bags is wide, and the other is that the filter type outside the bag is equipped with a continuous cleaning device.
When dealing with high dust content, pay attention to the structure of the bag filter (1) Try to make the dust fall directly into the ash hopper or add some baffles to reduce the amount of dust attached to the filter bag; (2) Prevent The frictional damage of the filter cloth should not cause the high-speed moving dust to directly impact the filter cloth.
