Dry-Type Pulse Jet Baghouse Dust Collector for Blast Furnace Gas
🌪 Efficient Dust Removal in High-Temperature, High-Dust Environments
The Dry-Type Pulse Jet Baghouse Dust Collector for Blast Furnace Gas is engineered to purify raw blast furnace gas (typically at temperatures around 260°C) using a dry filtration method. This system is essential in steelmaking environments, where raw gas contains a significant concentration of fine particles and needs to be cleaned before entering downstream applications such as hot blast stoves.
🛠 How It Works
Inlet Gas Distribution: Raw blast furnace gas enters the lower chamber of the baghouse via branch pipes from the main gas line.
Mechanical Pre-Separation: Initial coarse dust particles are separated by gravity before filtration.
Filtration: The gas flows upward through high-temperature-resistant filter bags, where fine particles are trapped on the outer surfaces of the bags.
Clean Gas Outlet: Cleaned gas is collected in the upper chamber and directed out through the clean gas duct to the hot blast stove or other systems.
Pulse Jet Cleaning Cycle:
As dust builds up on the filter bags, differential pressure increases.
When a preset pressure is reached, a signal is sent from the PLC-based electrical control system.
Valves close to isolate a chamber, and a pulse of nitrogen gas is injected to expand the filter bags rapidly, dislodging the dust cake.
The dust falls into the hopper below and is removed via rotary valves.
After a brief settling period, valves reopen and the chamber resumes filtration.
