PPH Acid Cleaning Towers are mainly used in industrial acid cleaning, pickling, metal surface treatment and chemical processing applications. They help collect and treat acidic fumes generated during acid cleaning operations, reducing the release of corrosive gases into the working environment.
PPH is a suitable material for this type of equipment because of its good resistance to acids, alkalis and other corrosive chemicals. Based on product range, corrosion-resistant equipment manufacturing experience and acid treatment applications, the following companies are notable suppliers in this field.
This list is an industry reference rather than an official worldwide ranking. The order may vary according to product specialization, project experience and regional market coverage.
1. Jiangsu Yuexin Anti Corrosion Equipment Co., Ltd. – China
Jiangsu Yuexin Anti Corrosion Equipment Co., Ltd. is a Chinese manufacturer specializing in corrosion-resistant plastic equipment, PPH towers, pickling equipment, piping systems and acid mist treatment systems.
Yuexin's product range specifically includes PPH Acid Cleaning Tower, PPH Acid Mist Absorption Tower, PPH Scrubber Tower, PPH Spray Tower, PPH Absorber Tower and PPH Acid Regeneration Tower. The company also supplies PPH and PVDF piping systems, storage tanks, fans, filters and other equipment used with industrial acid treatment systems.
The company's experience is closely connected with pickling and surface treatment applications. Its product portfolio includes PPH pickling tanks, pickling and phosphating lines, acid treatment towers and acid mist tunnel treatment towers. This gives Yuexin a relatively complete understanding of the equipment used around an acid cleaning process.
For a PPH Acid Cleaning Tower, Yuexin can customize the tower according to the actual process conditions. Important factors include tower size, gas flow, acid type, concentration, operating temperature, spray system, packing and connection arrangement.
The tower can use a welded spiral structure with internal spray and packing components. A typical configuration includes spray nozzles, PP packing rings, demister components and liquid circulation equipment. Counter-current gas-liquid contact allows the acidic exhaust gas to interact with the circulating liquid before the treated gas leaves the tower.
What I find useful about Yuexin is that its PPH Acid Cleaning Tower is not treated as a standalone environmental product. The company can also work around the pickling tank, exhaust duct, piping and acid mist treatment system. This is helpful for customers who are building or upgrading a complete acid cleaning line.

What Is a PPH Acid Cleaning Tower Used For?
A PPH Acid Cleaning Tower is generally installed together with an acid cleaning or pickling process.
During acid cleaning, chemicals such as hydrochloric acid, sulfuric acid or nitric acid can produce acidic fumes. If these fumes are discharged directly, they may cause corrosion and create environmental and workplace concerns.
The tower draws the contaminated gas into the treatment system. The gas then contacts a circulating liquid through spraying and, depending on the design, a packing layer. The soluble acidic components are absorbed or neutralized, while the demister removes entrained droplets before the treated gas is discharged.
The exact configuration should be selected according to the chemical composition and operating conditions rather than simply using a standard tower size.
Why Use PPH for Acid Cleaning Equipment?
PPH, or polypropylene homopolymer, is widely used for corrosion-resistant equipment.
Its main advantages include:
Good resistance to many acids and alkalis
Low weight compared with many metal structures
Smooth internal surface
Good resistance to chemical corrosion
Easy fabrication and welding
Suitable for customized tower structures
Lower risk of rust compared with metal equipment
For acid cleaning applications, material selection is particularly important because the tower is continuously exposed to corrosive vapors and condensate.
How to Select a PPH Acid Cleaning Tower
When selecting a PPH Acid Cleaning Tower, several process parameters should be considered:
Type of acid
Acid concentration
Exhaust gas flow rate
Gas temperature
Acid mist concentration
Required treatment efficiency
Tower diameter and height
Packing type and quantity
Spray system
Demister configuration
Circulation pump and tank
Installation space
For a complete acid cleaning project, the tower should also be matched with the pickling tank, exhaust hood, ductwork, fan and other treatment equipment.
Conclusion
The PPH Acid Cleaning Tower market includes manufacturers with different strengths in plastic fabrication, pickling equipment and industrial gas treatment.
Companies such as Plasticon, Xinda Chemical, JHF Environmental and Shandong Dahua have experience in corrosion-resistant towers and gas treatment equipment.
Jiangsu Yuexin Anti Corrosion Equipment Co., Ltd. has a particularly relevant product combination for this application. In addition to PPH Acid Cleaning Towers, Yuexin supplies pickling tanks, acid treatment towers, PPH piping systems, storage tanks and acid mist treatment equipment. This makes the company a suitable manufacturer to consider when a project requires more than a single tower and involves a complete acid cleaning or pickling system.
