Description

Technical Field

[0001] The utility model relates to the technical field of carbon black production, in particular to a bottom discharging mechanism of a bag filter for carbon black production. Background Art

[0002] Bag filters are crucial equipment in the carbon black production process. After the crude oil reacts in the reactor, the process gas containing carbon black is cooled to 250°C and enters the main bag filter. It then falls into the bag filter hopper. The carbon black collected by the main bag filter enters the air conveying system through its airtight valve. The bag filter exhaust is then transported to the off-site area for use by an exhaust gas booster fan. Once in the air conveying system, the carbon black is transported by air, passed through a micro-particle crusher to pulverize impurities, and then sent to the collection bag filter via an air blower. The carbon black is collected in a powdered carbon black storage tank, and the exhaust gas from the collection bag filter is sent to the off-site area for use in power generation equipment. However, due to the extremely small repose angle of carbon black, the typical bag filter cone is relatively long, requiring a large amount of building space. This, in turn, affects the compactness of the overall production line layout and results in significant space waste. In light of this, in-depth research into these issues led to the present case.
