The chamber pulse jet bag filter adopts the filtering method to remove the fine particles in the flue gas which are difficult to remove by other methods, and has high dust removal efficiency. There is no moving parts inside the bag filter, and the filter bag can be inspected or replaced from the top of the dust collector. Its design features ensure the versatility and operation simplicity of the dust collector. Bag dust collectors have been widely used in many industries such as power, metallurgy, chemical, light industry, medicine, food processing and other industries. Bag-type dust collectors are often used in our daily life, and bring a lot of convenience to our lives. The advantages and disadvantages of the dust removal effect of the dust collector are related to many factors, but mainly depend on the filter material. The filter material of the bag filter is a cloth or felt woven from synthetic fibers, natural fibers or glass fibers. According to the nature of the flue gas, a filter material suitable for the application conditions is selected. Since the bag filter is so important to our lives, we have studied the bag bag and internal leak welding inspection and processing steps of the bag filter.
1. Determination of the location of the damaged bag: close the clean room lift valve by chamber and observe the change of the discharge concentration of the chimney outlet. If the outlet discharge concentration decreases or disappears, the chamber has a broken bag. Close the chamber poppet valve and continue to close the poppet valve in the next chamber until the chamber in which all the bad bags are located is identified.
2. the damage of the bag in the specific location of the indoor search: open the bag in the room inspection door, you can clearly see the dust on the flower plate, near the valve hole. Use a flashlight to illuminate the bag from the mouth of the bag. The bag with gray at the bottom of the bag may be a bad bag. Mark it with chalk and check all the bags. The cloth bag with dust on the flower board should be inspected carefully.
3. Disposal of damaged bag: Replace the damaged bag. If there is no spare bag, the plate hole can be temporarily closed. The method of temporary sealing can be: sealing the upper mouth, or taking out the bag cage, and the bag bottom is tied. After the damaged bag is processed, remove the dust marks.
