Open the access door above and look directly at the top and bottom of the bag. The cost of using phosphors is too high, but the method of observing the ash deposits in the filter bags in the above buildings does not accurately locate the damaged filter bags, and only a small range can be delineated. During the operation, the gas chambers were manually closed one by one while observing the discharge port to determine the chamber after the ash leakage.
- If there is a dust collector for the blow pipe, there will be dust on the blow pipe corresponding to the broken filter bag. This is easier to judge. The dust collector of the gas box pulse is not very easy to find. First look at which room has dust, and then look around the dust accumulation. There will be dust adhering to the bag mouth inside the broken dust collector bag.
- Observe the micro-positive pressure phenomenon in the sealed chamber or sealed space connected to the lower part of the dust hopper. If there is any, open the upper cover of the dust-blasting chamber and observe the bag hole of the dust collector. If there is ash coming out of the filter bag，then this one is damaged.
- If there is no micro-positive pressure working environment, the upper cover of the blowing chamber can be directly opened, and the fan can be operated to observe which bag hole has been extracted, and that bag is broken.
