Effectively removes hazardous gases and particulate pollutants, helping facilities comply
with environmental regulations while supporting sustainable production environments.
Wet Scrubber System
Environment division
Equipment Overview
A combined air pollution control system that simultaneously removes hazardous gases and particulate matter through a wet scrubbing process.
A Wet Scrubber is a wet-type air pollution control system that simultaneously removes hazardous gases (acidic, alkaline, and water-soluble gases)
and particulate matter by bringing contaminated air into direct contact with a scrubbing liquid.
It is particularly effective in treating water-soluble hazardous gases and high-temperature, high-humidity exhaust gases that are difficult to handle with dry-type air pollution control systems.
As a result, it is widely applied in industries handling hazardous chemicals,
including chemical processing, semiconductor manufacturing, electroplating, and pharmaceuticals.
Based on a detailed analysis of the target pollutants, WINTECH customizes every aspect of the system—including the selection of the scrubbing liquid, packing media specifications, and nozzle arrangement—to deliver maximum treatment efficiency.
작동 원리
STEP 01
Contaminated Air Inlet
Contaminated air containing hazardous gases
and particulate matter enters the scrubber
through the bottom or side inlet.
The inlet velocity and flow direction are optimized to maximize contact efficiency with the scrubbing liquid.
STEP 02
Passage Through the Packing Bed & Contact with Scrubbing Liquid
As the contaminated air passes through the packing layer filled with Pall Rings,
it comes into direct contact with the scrubbing liquid
(e.g., an NaOH solution for
acidic gases or a diluted H₂SO₄ solution for alkaline gases).
The packing media maximize the contact area
between contaminants and the scrubbing liquid,
thereby enhancing removal efficiency.
STEP 03
Gas-Liquid Separation (Mist Eliminator)
The gas stream passes through a mist eliminator (demister pad),
which separates gas from liquid by removing fine droplets (mist)
generated during the scrubbing process, preventing them
from being carried over with the cleaned air.
STEP 04
Clean Air Discharge & Scrubbing Liquid Recirculation
The cleaned air, with hazardous components removed, is discharged through the top outlet to the stack.
The used scrubbing liquid is collected in the sump tank and recirculated
by a circulation pump, while its concentration is
automatically maintained by a pH control system.
Target Pollutants
Acidic gases
HCl (Hydrogen Chloride), HF (Hydrogen Fluoride), H₂SO₄ Mist (Sulfuric Acid Mist), HNO₃ (Nitric Acid), SO₂ (Sulfur Dioxide), etc.
Alkaline gases
NH₃ (Ammonia), NaOH Mist (Sodium Hydroxide Mist), etc.
Water-Soluble Organic Gases
Formaldehyde (HCHO), Acetaldehyde (CH₃CHO), Low-Concentration VOCs, etc.
Odorous Compounds
Hydrogen Sulfide (H₂S), Mercaptans, Amines, etc.
Dust, Mist, Fume
Water-Soluble Dust, Acid Mist, Metal Fume, etc.
Applicable Industries
Facilities Emitting Hazardous Gases
(e.g., Chemical, Electronics, and Textile Plants)
Fume and Dust-Generating Facilities
(e.g., Machining, Rubber, Plastic, and Plating Facilities)
Odor-Generating Facilities
(e.g., Wastewater Treatment Plants and Sewage Sludge Treatment Facilities)
Permitting & Regulatory Compliance
Air Emission Facility Permitting & Registration (Article 23 of the Clean Air Conservation Act)
Compliance Verification for the Installation and Operation Standards of Hazardous Chemical Handling Facilities (Article 24 of the Chemicals Control Act)
Review and Preparation of the Chemical Accident Prevention Management Plan (CAPMP)
Design to Meet Dust Emission Standards
(5–50 mg/Sm³, depending on the industry and facility type, Appendix 8 of the Enforcement Rule of the Clean Air Conservation Act)
Startup Notification Support and Assistance with Water Pollution Discharge Facility Registration for Scrubbing Wastewater
As wet scrubbers are designed to treat hazardous chemicals directly,
compliance with the Chemicals Control Act
is required in addition to the Clean Air Conservation Act.
