How to install the dust bag?
Origin：Hefan Hit： Time：2020-01-21
Put two hands into the dust-removing cloth bag so that both thumbs press the spring expansion ring on the bag mouth outside the dust-removing cloth bag to release most of the grooves after fully contacting the groove with the flower plate mouth to restore the spring expansion ring in the recessed part. And contact with the mouth of the flower board. If you can put a circle of old filter cloth around the mouth of the flower plate to prevent the new dust bag from being scratched when you put the dust bag into the mouth of the flower plate, you can reduce the accidental damage of the dust bag. It should be noted that the bag cage should be supported before putting the dust-removing cloth bag into the flower plate mouth.
The dust collector is generally divided into several categories, such as bag type dust collector, cyclone dust collector, electrostatic dust collector, etc. The installation and analysis of the pulse dust bag is analyzed. The bag dust collector is composed of the upper box, the ash hopper, and the blowing pipe. System, ash discharge system and other parts. Flue gas dust removal process: When the flue gas enters the ash hopper from the air duct, the heavy dust particles will fall into the ash hopper at the same time and be collected at the same time, the fine dust particles will continue to advance with the air, and will directly contact the dust bag Attached to the surface of the dust bag, the clean air is passed through the clean air exhaust duct and discharged into the atmosphere by the exhaust fan. It can be seen that the dust bag is an important part in the entire dust removal process and plays a decisive role in the dust removal efficiency of the flue gas. We should choose a good dust bag and use the correct installation method.
General failures and ways to avoid dust bags:
1. Burning: The reason for the burning of the dust removal bag is generally that the initial layer on the surface of the dust removal bag is not thick enough, and the temperature of the flue gas is too high.
2. Damage: Damage to the dust bag usually occurs in the middle of the dust collector. On a single dust bag, it usually occurs within 1 meter from the outlet of the dust bag.
3. The distance between the dust-removing cloth bags is too small, the cage bone is bent, etc. will cause damage between the dust-removing cloth bags.
4. When there is a hole or burr in the weld of the cage, or the rough surface caused by corrosion, it will also accelerate the damage of the dust bag.
5. Improper alignment of the venturi tube or pulse tube with the two ends of the dust bag will cause the air sprayed from the blow pipe to directly wash the upper part of the dust bag and cause damage.
6. Excessive filtering air speed will cause the initial dust layer to break up and cause excessive damage when it hits the dust bag. If the frequency of cleaning the dust bag is too high at this time, the polyester fiber of the dust bag will be loosened and the dust bag will be accelerated damage
