Flue Gas Spray Filtration System C Construction and Application Description
Application:
The flue gas filtration system is designed for final-stage exhaust gas purification. It removes fine dust and mist particles through a multi-stage process that includes extreme cooling spray treatment, dust removal, demisting, and stainless-steel mesh filtration. The process ensures clean, purified flue gas discharge that meets environmental emission standards.
General Configuration:
The system consists of two main spray towers and a terminal stainless-steel mesh filter:
1. First-Stage Spray Tower (Primary Scrubber):
Equipped with internal Pall Rings (Raschig Rings), this tower performs extreme cooling and initial dust removal from high-temperature exhaust gas.
The flue gas enters and collides directly with high-velocity spray jets, rapidly reducing its temperature and allowing dust particles to settle.
2. Second-Stage Spray Tower (Secondary Scrubber):
Also packed with Pall Rings, the secondary tower provides further dust and fine particle removal.
The cleaned gas is then guided to the induced draft fan (ID fan) for extraction.
3. Induced Draft Fan and Stainless-Steel G4 Mesh Filter:
The ID fan maintains negative pressure in the ducting system, drawing treated gas toward the outlet.
The exhaust passes through the final G4 stainless-steel mesh filter, achieving fine dust and mist separation before discharge.
