Description
Product Overview
Our PP corrosion-resistant spray scrubber is a specialized wet scrubbing system engineered to treat highly corrosive industrial exhaust gases, solving the long-standing pain point of equipment corrosion and leakage that plagues traditional metal scrubbers. At XiCheng EP, with over 15 years of experience in industrial air pollution control solutions, we have optimized this system to withstand the harshest chemical environments, supporting enterprises across multiple industries to meet strict environmental emission standards set by the EPA. Constructed from high-grade polypropylene (PP) material, this scrubber can stably operate in environments with pH values ranging from 1 to 14, effectively removing harmful acid mist, alkali fumes, and other corrosive pollutants from exhaust gas before they are released into the atmosphere.
How Does The PP Corrosion-Resistant Spray Scrubber Work?
This system adopts a counter-current spray washing mechanism to achieve efficient gas purification through 4 standardized processing steps:
Step 1: Gas Intake & Pre-treatment
The corrosive exhaust gas is first drawn into the scrubber tower from the bottom inlet. A primary baffle removes large particulate matter from the gas flow, preventing abrasion to the internal spray nozzles and ensuring smooth subsequent processing.
Step 2: Spray Washing & Neutralization
As the gas flows upward, it comes into full contact with the downward spray of neutralizing liquid. The high-pressure nozzles break the liquid into tiny droplets, maximizing the gas-liquid contact area. Pollutants such as acid mist are absorbed and neutralized by the liquid during this process.
Step 3: Demisting & Adsorption
After washing, the gas passes through a high-efficiency demisting layer. This layer captures the tiny liquid droplets entrained in the gas flow, preventing water mist from being carried out of the system and ensuring the dryness of the discharged gas.
Step 4: Clean Gas Discharge
The fully purified clean gas is then discharged through the top outlet of the tower, completely meeting the local environmental emission standards. The circulating washing liquid is collected in the bottom tank for recycling, reducing water consumption.

Application Industries & Use Cases
Our PP corrosion-resistant spray scrubber is widely applied in industries that generate corrosive exhaust gas, providing reliable emission compliance solutions:
Chemical Manufacturing
In chemical production processes, this scrubber effectively treats corrosive waste gas generated from raw material processing and reaction procedures, removing harmful acid/alkali pollutants to protect the surrounding environment and worker health.
Electroplating & Metal Finishing
For electroplating and pickling workshops, the system captures acid mist generated during the metal surface treatment process, solving the problem of acid gas corrosion to workshop equipment and meeting strict workplace air quality standards regulated by OSHA.
Pharmaceutical Production
Pharmaceutical factories often produce corrosive solvent fumes during drug synthesis and extraction. Our scrubber efficiently removes these pollutants, helping pharmaceutical enterprises meet GMP and environmental compliance requirements.
Printing & Coating Industry
In printing and coating processes, the system treats the corrosive organic acid fumes and volatile pollutants, ensuring the exhaust gas meets emission standards while improving the workshop’s air environment.
Wastewater Treatment Plants
Wastewater treatment stations will produce corrosive odorous gases during the aeration and sludge treatment process. This scrubber can effectively neutralize these gases, eliminating odor pollution for surrounding communities.
Laboratories & Research Institutes
For laboratories that handle corrosive chemical experiments, the compact PP scrubber provides safe exhaust gas treatment, protecting researchers from exposure to harmful gases and ensuring lab safety compliance.
Successful Customer Case
A large electroplating factory in Hebei, China, was facing a critical emission compliance issue. Their original stainless steel spray scrubber had severe corrosion and leakage after only 2 years of operation, leading to unqualified acid mist emission and a warning from the local environmental protection bureau. They turned to XiCheng EP for a solution. We provided them with a customized 10,000 m³/h PP corrosion-resistant spray scrubber, tailored to their specific acid gas composition. After installation, the system achieved a 98.5% acid mist removal rate, and the exhaust gas fully met the local industrial emission compliance standards. Up to now, the equipment has been running stably for 5 years without any corrosion or leakage problems. The client reported that their annual maintenance cost has been reduced by 45% compared to the old equipment, and they no longer need to worry about environmental compliance risks.
