Industrial Wet Scrubber System for Acid Mist Waste Gas Treatment

Product Overview

XICHENG EP LTD has years of experience in industrial waste gas treatment, specializing in custom industrial wet scrubbers designed to efficiently eliminate acid mist waste gas from industrial production workshops. Unlike generic gas treatment solutions, our vertical-structure scrubbers utilize packing absorption technology to tackle corrosive exhaust gases like HCl, HF, and SO2, solving common pain points such as non-compliant emissions, equipment corrosion, and high maintenance costs for manufacturing facilities.

Made of high-quality polypropylene (PP) sheets through precision forming and welding, our scrubbers offer excellent corrosion resistance against acidic gases, meeting the industrial equipment material standards recommended by the Plastics Industry Association. Our system integrates three core parts: the main tower body with storage tank, packing layer, spray layer, defogging layer, observation window and base; the circulating water system with vertical pump, PP air duct system, spiral nozzles and automatic water level control; and the intelligent dosing system with PH online detector, metering pump and mixing barrel.

How Does The Industrial Wet Scrubber Work?

Step 1: Gas Intake & Pre-treatment

Acid mist exhaust gas is first collected by suction hoods or other gas collecting devices, then transported through our corrosion-resistant PP air ducts. Under the action of an anti-corrosion centrifugal fan, the exhaust gas is drawn into the scrubber tower in negative pressure mode to avoid gas leakage.

Step 2: Spray Washing & Neutralization

The exhaust gas flows upstream inside the tower, with the wind speed slowing down gradually. In the packing layer with large specific surface area, the gas fully contacts with sodium hydroxide alkali solution. Acid-base neutralization reaction takes place here, absorbing and removing the harmful acidic components from the gas.

Step 3: Demisting & Adsorption

After the neutralization process, the gas passes through the top demisting layer, which removes the water mist carried in the gas flow. This step ensures that no excess moisture is discharged into the atmosphere, preventing secondary pollution.

Step 4: Clean Gas Discharge

Finally, the purified clean gas is sent to the chimney system by the centrifugal fan, and discharged at a height of 15 meters, fully complying with the industrial air contaminant regulations set by OSHA, ensuring your facility meets all environmental standards.

Core Advantages of Our Industrial Wet Scrubber

Application Industries & Use Cases

Our industrial wet scrubbers are widely used in various industries to solve different waste gas treatment problems, effectively reducing harmful emissions, aligning with the industrial air emission guidelines from EPA.

Metal Surface Treatment

Effectively treats acid mist generated during hardware pickling and anodizing processes, protecting workers from corrosive gas and ensuring emission compliance.

Glass & Electronics Manufacturing

Handles waste gas from glass panel etching and electronic component production, removing harmful acidic gases to maintain a clean production environment.

Laboratory & Research Facilities

Purifies exhaust gas from laboratory fume hoods, eliminating toxic and odorous gases to protect researchers’ health and laboratory air quality.

Petrochemical Industry

Treats waste gas from petrochemical reactors, removing various harmful pollutants to meet the strict environmental requirements of the petrochemical industry.

Biopharmaceutical Industry

Handles odorous and harmful gases generated during pharmaceutical production, meeting GMP standards and ensuring a safe production environment.

Power Plants

Removes acidic gases from power generation processes, helping power plants reduce pollution and meet national emission standards.

Successful Customer Case

Last year, we delivered a custom industrial wet scrubber solution to a hardware pickling factory in Guangdong, China. The client was facing serious issues: their original gas treatment system failed to meet local emission standards, resulting in a 50,000 RMB environmental fine and production suspension risks.

After on-site inspection, we customized a 12,000 m³/h PP wet scrubber with automatic dosing system for their HCl acid mist waste gas, part of our custom waste gas solutions service. After installation, the client achieved 96% acid mist removal rate, with outlet HCl concentration reduced to 8PPM, fully complying with national emission standards.

The system has been running stably for over 2 years with only routine maintenance, saving the client over 200,000 RMB annually in potential fines and energy costs. Want to know how we can solve your waste gas problem? Get in touch with our engineers now.

Technical Specifications

Frequently Asked Questions

What types of waste gas can an industrial wet scrubber treat?

Our industrial wet scrubbers can treat a wide range of toxic and harmful gases including NOX, SO2, H2SO4, HCl, HF, SiF4, CO2, etc. They can also handle odorous substances such as ammonia, hydrogen sulfide, phenolic, formaldehyde, methanol, and amines, suitable for chemical, electroplating, pharmaceutical, and many other industries.

What is the purification efficiency of your wet scrubber?

Our wet scrubber achieves up to 95% removal rate for acid mist waste gas, with the outlet pollutant concentration lower than 10PPM, which fully meets strict global emission standards to keep your facility compliant.

Can you customize the scrubber according to our site conditions?

Yes, we offer fully customized solutions. We can adjust the size, air flow capacity, material, and layout of fans and pumps based on your specific waste gas conditions, site space, and unique requirements.

How long is the service life of your PP wet scrubber?

Made of high-quality anti-corrosion PP material, our wet scrubbers can last for over 10 years with proper maintenance, much longer than traditional metal scrubbers in acidic environments.

What information do you need for a custom quote?

To provide the most accurate solution, we will need: the type and concentration of your waste gas, total required air flow, site space conditions, power supply voltage, your existing wastewater treatment situation, and water supply conditions. This helps us design the perfect scrubber for you.
