Application and Function of Ozone Decomposition Catalysts in Air Compressors
I. Core Application Scenarios
During the compression process of air in an air compressor, due to high-pressure discharge, local high temperatures, or oxidation of lubricating oil, trace amounts of ozone (O₃) may be produced. Ozone decomposition catalysts are mainly used in post-treatment systems of compressed air, and are particularly suitable for:
Medical/Food Grade Compressed Air: It is necessary to strictly control the residual of harmful gases such as ozone to avoid oxidative damage to products or the human body.
Air for Precision Instruments: For scenarios such as electronic chip manufacturing and laboratory analysis, ozone should be prevented from causing equipment corrosion or data interference.
Ventilation in Enclosed Spaces: For places like compressor rooms and underground projects, by treating the ozone in the circulating air, the safety of the working environment can be improved.
2.Main Functions:
Efficient Decomposition of Ozone:
The catalyst (usually composed of MnO₂, activated carbon, and precious metals such as Pd, Pt as active components) decomposes ozone at normal or medium temperatures into harmless oxygen (2O₃ → 3O₂), reducing the ozone concentration in the air to a safe limit (typically ≤ 0.1 ppm, in line with occupational exposure standards).
Protection of Downstream Equipment and Pipelines:
Ozone has strong oxidizing properties. Its long-term presence will accelerate the aging of rubber seals in post-treatment equipment (such as dryers, filters) of the compressor and corrosion of metal pipelines. The catalyst can reduce such losses and extend the lifespan of the equipment.
Improvement of Air Quality:
Preventing ozone in compressed air from entering end applications (such as pneumatic tools, breathing air) to avoid irritation to the respiratory tract and mucous membranes of the human body or oxidation discoloration of sensitive materials (such as plastics, coatings).
