A spray tower, also known as a wet scrubber or wet dust collector, is an important activated carbon making machine used in activated carbon plants. The spray tower uses water to come into contact with dusty gas. Through washing, it separates the dust from the gas.

AGICO cement can customize various models and specifications of spray towers, our spray tower can be widely applied in activated carbon plants, chemical industry, printing, environmental protection, and other industries.

spray tower case

The spray tower consists of components such as the tower body, spray device, demisting device, and inspection port.

spray tower structures

Working principle of spray tower

The described system is a two-phase countercurrent flow packed tower absorption system for acid scrubbing. The waste gas enters the acid scrubbing tower from the lower inlet and flows tangentially into the tower. With the power of a ventilation fan, the gas quickly fills the inlet section and then evenly rises to the first layer of the packing section.

On the surface of the packing, chemical reactions occur between acidic (or alkaline) substances in the gas phase and alkaline (or acidic) substances in the liquid phase. Reaction products (mostly soluble acids or alkalis) flow into the lower liquid storage tank with the absorbing liquid. The incompletely absorbed acidic (or alkaline) gas continues to rise into the second layer of the spraying section.

Working principle of spray tower

In the spraying section, the absorbing liquid is sprayed out at high speed from uniformly distributed nozzles, forming countless small droplets that mix and contact with the gas thoroughly. The gas undergoes further chemical reactions. Then, the acid (or alkaline) gas rises to the second layer of the packing section and spraying section to undergo a similar absorption process as the first layer. The nozzle density and spraying pressure in the second layer are different, leading to a different range of acidic (or alkaline) gas concentration absorption.

The contact process between the gas and liquid in the spraying and packing sections involves heat and mass transfer. Controlling the gas flow rate and residence time ensures sufficient and stable absorption. The upper part of the acid scrubbing tower is the demisting section, where the liquid droplets carried by the gas are removed. After treatment, clean air is discharged into the atmosphere through the exhaust pipe at the top of the acid scrubbing tower.
