In the spray section in the absorption liquid from the nozzle ejected uniformly, the formation of tiny droplets, and mixed gas full contact, continue to react, then acid (alkaline) gas up to two grade packing section, spray section and the first stage similar absorption process.

Working principle of peculiar smell

Acid and alkaline gas purification tower belongs to two phase reverse flow packing absorber. Hongfeng said waste gas from the exhaust gas purification tower inlet gas processing purification tower along the bottom of the tower body to cut into, powered by fan, quickly filled with inlet space, then evenly through all flow up to the first grade filler absorption section.

On the surface of packing, the gas phase (acidic or alkaline) alkaline material and liquid phase (or acid) of chemical reactions, the reaction material (mostly soluble acid (alkali) class) with the absorption liquid flows into the lower reservoir. The incompletely absorbed acidic (or alkaline) gas continues to rise into the first stage of spray section. In the spray section in the absorption liquid from the nozzle ejected uniformly, the formation of tiny droplets, and mixed gas full contact, continue to react, then acid (alkaline) gas up to two grade packing section, spray section and the first stage similar absorption process.

The second stage is different from the first stage nozzle, and the concentration of acid (alkaline) gas varies with the injection pressure. The process of two-phase contact in spray section and packing section is also the process of heat transfer and mass transfer. By controlling the flow velocity and residence time of the empty tower, the process is sufficient and stable. The top part of the waste gas treatment tower is the mist removing section, and the absorption liquid droplets trapped in the gas are removed here, and the treated clean air is discharged into the atmosphere from the exhaust pipe of the exhaust gas purification tower.
