Product Description
Negative pressure dust collection system refers to the configuration where the fan is installed after the dust collector. The fan sucks the dust-laden flue gas through the dust collector, where filtration occurs under negative pressure, and the purified gas is pushed by the fan into the chimney for discharge.
The fan creates negative pressure inside the dust collector, drawing in dust-laden gas for filtration; purified gas is discharged through the fan.
JDDM series negative pressure pulse dust collector is the mainstream equipment for SAF flue gas purification, adopting long-bag low-pressure pulse technology.

Positive Pressure Dust Collector System Industrial Baghouse Dust Collector
Positive Pressure Baghouse Dust Collection System 1. Definition & Working Principle Positive pressure dust collection system refers to the configuration where the fan is installed before the dust collector. The fan pushes the dust-laden flue gas into the dust collector, where the gas is filtered through filter bags under positive pressure, and the purified gas is directly discharged or sent for subsequent treatment. The fan pushes dust-laden flue gas under positive pressure
SAF Flue Gas Purification System Fume Treatment Plant High Efficiency
SAF Flue Gas Purification System/ Fume Treatment Plant During the smelting process, electric arc furnaces generate large amounts of high-temperature, high-dust-content flue gas, which must be equipped with efficient dedusting systems to meet environmental emission requirements. Baghouse dust collectors are the mainstream equipment for arc furnace dust removal, achieving dust removal efficiencies exceeding 99.5% and controlling outlet emissions to ≤10 mg/m³ or even lower.
