Industrial furnace deduster design: The bag dust collector for furnace consists of a shell, ash hopper, ash discharge device, support, and pulse cleaning system. When the dusty gas enters the collector through the inlet, it first encounters the inclined baffle between the inlet and outlet airways, causing the airflow to turn and flow into the ash hopper. The airflow slows down due to inertia, allowing the coarse particles to fall directly into the ash hopper, serving as a preliminary dust collection. The airflow entering the ash hopper then turns upward and passes through filter bags with a metal frame inside. The dust is collected on the outer surface of the filter bags. The purified gas then enters the clean room above the filter bag chamber and is channeled out through the exhaust pipe. The inlet of the PPW type dust collector is located on the ash hopper, where the airflow first hits the baffle at the end of the inlet pipe, functioning similarly to the aforementioned principle. The shell is divided into several independent dust collection chambers by baffles, and each chamber is cleaned sequentially at given time intervals. Each chamber is equipped with a lifting valve that closes during cleaning to cut off the filtered airflow through the chamber. The pulse valve then opens, injecting high-pressure air into the filter bags to remove the dust on the outer surface. The pulse blowing width and cleaning cycle of each dust collection chamber, as well as the cleaning program controller, run automatically and continuously.
