Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a novel bag dust collector. Background Art

[0002] Bag filters, also known as bag-type dust collectors, are an important type of dust removal equipment widely used for dust control in industries such as steel, cement, chemicals, and power generation. They utilize filter bags to filter dust-laden air, separating dust from the air and offering high efficiency, stability, and reliability. The operating principle of a bag filter is relatively simple. Dust-laden air enters through the air inlet. As it passes through the ash hopper, large dust particles are separated by gravity and inertia, falling directly to the bottom of the hopper. The air then enters the filter bag filtration area of the middle chamber. As the air passes through the filter bags, dust is trapped on the outer surface of the bags. The purified air then enters the upper chamber through the bag openings and is discharged through the air outlet. As filtration time increases, the dust layer on the filter bags gradually thickens, increasing the resistance of the dust collection system. When the resistance reaches a set value, the dust cleaning device begins operation. By closing a chamber lift valve to cut off the filtered airflow, and then opening the electromagnetic pulse valve, the compressed air rapidly expands within the upper housing in a very short time, rushing into the filter bag, causing the bag to expand, deform, and vibrate. Under the action of the reverse airflow, the dust adhering to the outer surface of the filter bag is peeled off and falls into the ash hopper. However, after long-term use and repeated cleaning of the filter bags, the stubborn dust stains adhering to the filter bags cannot be fully removed in existing bag filters, resulting in a gradual decline in filtration efficiency. Furthermore, existing bag filters cannot be cleaned or replaced quickly and easily. Therefore, a new type of bag filter is urgently needed to solve these problems. Utility Model Content
