Pneumatic pulse dust collector

When the gas shock pulse dust collector is working normally, the dusty gas enters the ash hopper through the air inlet. Due to the rapid expansion of the gas volume, some of the coarser dust particles fall into the ash hopper due to inertia or natural settling, while the rest of the dust particles rise into the bag chamber with the airflow. After being filtered by the filter bag, the dust particles are trapped on the outside of the filter bag. The purified gas enters the upper box through the inside of the filter bag and is then discharged into the atmosphere through the valve plate hole and exhaust outlet, thus achieving the purpose of dust removal. As the filtration continues, the resistance of the dust collector also increases. When the resistance reaches a certain value, the dust cleaning controller issues a dust cleaning command, first closing the lifting valve plate and cutting off the filtered airflow; Then, the dust cleaning controller sends a signal to the pulse solenoid valve. As the pulse valve sends high-pressure reverse airflow used for dust cleaning into the bag, the filter bag rapidly swells and produces strong shaking, causing the dust on the outside of the filter bag to shake off, achieving the purpose of dust cleaning. Due to the fact that the equipment is divided into several box areas, the above process is carried out box by box. While one box area is cleaning, the remaining box areas are still working normally, ensuring the continuous and normal operation of the equipment. The key to being able to handle high concentration dust is that this strong cleaning requires a short cleaning time (only 0.1-0.2 seconds for one injection).
