01
Contaminated Gas Inflow
Process gas containing dust and gaseous pollutants is captured.
AIR POLLUTION CONTROL
Wet Scrubber
Optimizing contact between scrubbing liquid and contaminated gas to treat dust and gaseous substances together.WET SCRUBBER SYSTEM
Bringing contaminated gas into contact with scrubbing liquid
to treat dust and hazardous gas together.
A wet scrubber directly contacts contaminated gas with water or a chemical solution to remove dust and water-soluble gaseous substances. Using a scrubbing liquid matched to the target substance allows complex pollutants to be treated in a single process.
Treatment efficiency depends on the gas-liquid contact area, circulating water condition, chemical concentration, and gas-to-liquid ratio. Changjo Eng analyzes airflow and pollutant characteristics to design the contact method and circulation system.
PROCESS FLOW
Treatment Process
Pre- and post-treatment stages are combined to fit each site's conditions.02
Scrubbing Liquid Spray
A scrubbing liquid suited to the target substance is sprayed evenly.
03
Gas-Liquid Contact
Contact between gas and liquid is maximized in the packing bed or spray zone.
04
Mist Separation & Discharge
Droplets are removed from the treated gas before it is safely discharged.
GAS-LIQUID CONTACT
Balancing contact efficiency and circulating water management
We design the flow velocity, packing bed, and nozzle layout so gas and scrubbing liquid make sufficient contact. At the same time, we manage the circulating water's concentration, pH, and sludge condition to prevent reduced treatment efficiency and nozzle clogging.
- Scrubbing Liquid SelectionA liquid matched to the pollutant's solubility and reactivity
- Gas-to-Liquid Ratio DesignOperating conditions that balance treatment efficiency and circulating water volume
- Mist EliminationA separation structure that keeps scrubbing liquid from carrying downstream
- Circulating Water ManagementA management system that monitors pH, concentration, and sludge
DESIGN POINT
Raising both treatment efficiency and operability together.
Combined Treatment
Dust and water-soluble gaseous pollutants can be treated in a single facility.
Chemical Control
Chemical dosing and circulating water conditions can be adjusted to match the pollutant load.
Corrosion Response
Corrosion-resistant materials for the body and piping are selected based on scrubbing liquid and gas characteristics.
