Product Description
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 into the dust collector. As gas passes through the filter bags, dust is trapped, and purified gas is discharged from the top.
- Compared with negative pressure filtration reverse blowing cleaning, equipment weight is 20% lighter
- Initial investment is reduced by 20%
- Low system resistance, fan power consumption saves 10%
- "Three-state combined" cleaning technology completely solves secondary adsorption
- PLC control with simulation panel display and LCD Chinese character display
"Three-state combined" cleaning technology: filtration, reverse suction, and settling
HB series positive pressure large baghouse dust collector is a mature product specially developed for SAF, adopting positive pressure working mode and "three-state combined" cleaning technology.

Negative Pressure Baghouse Dust Collection System 1. Definition & Working Principle 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
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.
