1 judgment analysis Bag dust collector chimney ash is the most common problem in production operation, generally can be divided into two cases of continuity and discontinuity: 1) Continuous ash is mostly air duct partition leakage (more often during commissioning) or broken bags in each room; 2) Discontinuous ash is mostly caused by damage to the filter bag of a certain chamber, poor sealing of the bag mouth or trachoma of the plate weld. It is unlikely that each room will have a broken bag, so this article only analyzes the latter. When there is a continuous ash in the chimney, most enterprises take the operation and then use the opportunity of shutdown maintenance, which not only seriously pollutes the environment, but also causes the piston rod of the lifting cylinder to be inflexible due to sticky ash. It is stuck, in addition, it will cause the fan impeller to stick to the ash to increase the vibration amplitude and affect the normal operation of the equipment. However, the shutdown process will bring great economic losses to the production. 2 measures to deal with discontinuous ash online 1) During the automatic operation of the bag filter, while carefully observing the wind chimney, carefully watch the first room for pulse work. If a room has a broken bag or a flower plate with trachoma, the chimney will be grayed out before the pulse. Reducing or not taking off (the lifting cover of the suction port is covered when the pulse is pulsed, and the room is in a non-working state at this time), and the degree of smoke at the moment when the lifting cover is lifted after the pulse is significantly increased (indoor dust accumulation) It will be lifted by the impact of the pulse. If this method is not easy to judge, it can be judged by manually closing the lifting cover manually. When the lifting valve plate of a certain chamber is closed, it is not ash or ash. The small possibility is that the suction valve cover is not tight or there are multiple chamber breaks.), this room has a broken bag. 2) When it is judged that there is a broken bag in a certain room or a trachoma in the flower board, the inspection port can not be opened immediately. The lifting cover of the room should be manually closed first, and the solenoid valve and the control for controlling the lifting and lowering of the lifting cylinder of the room should be controlled. This step is especially important when the pulsed valve coil of this chamber is unplugged to prevent personal injury caused by the poppet or pulse valve working automatically during processing. 3) After finishing the above work, you can open the observation door of this room to confirm the number and position of the broken bag or trachoma (there is generally dust accumulation around the bag opening, and the filter bag is full of dust). 4) Remove the damaged filter bag and replace it. If there is no new filter bag or the damaged filter bag is not easy to take out, you can use the cloth to block the damaged filter bag mouth and then replace it with a stoppage. It can be temporarily treated by applying a sealant. The structure of the bag filter is shown in Figure 1. Online judgment and treatment of bag dust collector breaking bag 3 effect analysis After adopting this method, our company has processed the bag dust collector to break the bag more than 10 times and treated the trachoma in the flower board room twice, which not only avoids many downtime accidents, but also solves the environmental pollution problem caused by the ash from the bag filter. The production hazard brought to the equipment.

Our company has three sets of cement grinding systems, which were officially put into production in October 2010. The annual output of cement is more than 2.4 million tons, and more than 30 bag filters are deployed to achieve the status of smokeless production. However, the management and maintenance of many dust collectors have caused a lot of troubles in production. With continuous exploration and improvement in production practice, our company has gained a lot of experience in this area, and concluded that a set of online processing bag dust collector broke the bag. And the valuable experience of the air leakage of the flower board not only greatly improved the on-site environment, but also avoided many shutdowns for the production system, ensuring the continuous and stable operation of the equipment.
