Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically a bag filter for smoke and dust removal from cupola furnace exhaust gas. Background Technology

[0002] A device that separates dust from flue gas is called a dust collector or dust removal equipment. The performance of a dust collector is expressed by the amount of gas it can handle, the resistance loss of gas passing through the dust collector, and the dust removal efficiency. Meanwhile, the price, operation and maintenance costs, service life, and ease of operation and management of dust collectors are also important factors to consider in evaluating their performance. Dust collectors are commonly used facilities in boilers and industrial production. An existing patent, patent publication number CN108465306B, discloses a baghouse dust collector, which includes a dust collection chamber, a purification chamber, an ash hopper, and support legs. A first partition is provided between the dust collection chamber and the purification chamber, and a second partition is provided between the dust collection chamber and the ash hopper. The first partition has several first through holes, and the second partition has several second through holes. A straight pipe is fixed between each first through hole and its corresponding second through hole. Each straight pipe has several rows of ventilation holes on its wall. Each straight pipe contains a frame, and each frame is fitted with a filter bag. The side wall of the dust collection chamber has an air inlet, the top of the purification chamber has an air outlet, and the bottom of the ash hopper has an ash discharge valve. The bag filter provided by this invention ensures that the dust-laden airflow does not affect the ash hopper after entering the dust collection chamber, thus avoiding "secondary dust generation" of the dust originally deposited in the ash hopper.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: in practical applications, it is inconvenient to disassemble and install components, which affects the ease of use of the dust collector, reduces its efficiency, and makes subsequent operation inconvenient for staff. Therefore, we propose a bag filter for cupola exhaust gas smoke and dust removal to solve the above-mentioned problems. Utility Model Content
