The precast concrete wet scrubber is a cost-effective solution known for its durability and efficiency. Concrete is renowned for its durability. The precast concrete wet scrubber has a flue path lined with Acid-resistant tiles adhering to IS 4457:2007 (Class-1). This makes the scrubber highly suitable for corrosive applications, enhancing its longevity. On average, the precast concrete wet scrubber has an operational life of 25 years.
Given that the wet scrubber is made of concrete, the flue gas temperature remains relatively stable as it passes through the scrubber. The precast concrete flue path, lined with acid-resistant tiles, have much lower thermal conductivity. This results in enhanced natural draft through the wet scrubber and chimney.
The design of the precast concrete wet scrubber is highly efficient. In the first stage, the venturi structure ensures that 100% of the flue gas passing through is in contact with the scrubbing medium. In the second stage, the scrubbed flue gas passes to the dry scrubber through the water storage tank, skimming over the water surface in a wet bottom process that eliminates almost all suspended particulate matter (SPM) in the flue gas. In the third stage, the flue gas passes through the dry precast concrete structure, where water molecules are captured before entering into the chimney.
Maintenance is simplified by designing the structure in such a way that key components can be replaced in minutes. The precast concrete wet scrubber, which features separate wet and dry scrubbers and a separate water tank. This design makes it easier to maintain and also reduces the cleaning cycle period.
