Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a high-pressure offline pulse bag filter. Background Technology

[0002] Pulse jet baghouse dust collectors are a type of high-efficiency dust removal equipment widely used in industrial production processes, especially in places where it is necessary to remove dust from the air. Its working principle is to clean the filter bags through periodic pulse airflow, thereby achieving the purpose of removing accumulated dust. Pulse jet baghouse dust collectors have the advantages of high dust removal efficiency, low operation and maintenance costs, and compact structure, and therefore have important applications in industries such as cement, metallurgy, power, and chemical engineering.

[0003] A bag-type high-pressure pulse dust collector, such as the one disclosed in CN221981871U, includes a dust collector body. A support plate is installed inside the dust collector body for support. Both sides of the support plate have baffles for separation. A filter bag cylinder for filtration is located at the bottom of the support plate. A filter element is installed on the outside of the filter bag cylinder and installed inside the dust collector body. Through the corresponding cooperation of various structures, the airflow, after circulating within the dust collector body, is conveyed through the support plate to the filter bag cylinder for filtration. Impurities in the dust are filtered into the filter bag cylinder, while the filtered airflow is discharged to the outside of the filter bag cylinder, then filtered again by the filter element before being discharged. During filtration, this effectively prevents dust-laden airflow from accumulating in one place, thus avoiding a high filtration load on the device.

[0004] The aforementioned patent proposes that high-pressure airflow can be delivered into the nozzle, and the airflow is sprayed into the filter bag cylinder through the nozzle, generating strong impact and vibration, which knocks the dust off the inner wall of the filter bag cylinder. However, during the use of the bag filter, the dust is discharged from the bottom opening of the bag filter, and the dust accumulates at the bottom of the dust collector for a long time, especially in the ash hopper or ash discharge port area. This dust will gradually accumulate, causing blockage of the ash discharge port and affecting ash discharge. Utility Model Content
