Let the exhaust gas take a "bath" —— the spray tower, the first step of industrial purification

#Industry ·2026-02-24

When high-temperature, high-humidity, and high-concentration exhaust gases rush out of the pipeline, the first thing they encounter is not high-altitude discharge, but the dense water curtain of the spray tower. Layered atomizing nozzles break down the absorption liquid into micron-sized droplets, instantly increasing the surface area by a thousandfold. Acid-base neutralization, particle capture, and cooling and dust removal are all integrated into a single process. PP, FRP, 304, 316L... Different materials correspond to different corrosion levels. The modular design allows for quick assembly like Lego blocks, whether it's a 2-meter or 8-meter diameter. The three classic structures of packing layers, swirl plates, and demisters can still maintain a purification efficiency of over 95% even with an air velocity of 2.5 m/s in an empty tower. This directly reduces the operating costs of the entire exhaust gas system and eases the burden on downstream RTO, activated carbon, and photocatalytic reactors. What about wastewater? Automatic dosing and online pH monitoring of the circulating water tank ensure that the discharge meets national standards. What about northern winters? Double-layer insulation with steam heating and low-level shutdown ensure stable operation even at -20°C. From Jiangsu Chemical Park to Guangdong Electronics Factory, from lithium battery coating to waste incineration plants, the spray tower acts like a low-key vanguard: it doesn't steal the spotlight, but intercepts PM, HCl, NH₃, and H₂S first, making the environmental data no longer shocking. Choosing a spray tower isn't just to pass inspections, but to give equipment a long lifespan, provide workers with clean air, and secure a sustainable waste discharge permit for the enterprise. Let exhaust gases take a "bath" first, then meet emission standards — the spray tower uses one ton of water to create a blue sky.
