Abstract
The use of incinerators for waste management generates hazardous hot exhaust gases, necessitating an efficient wet scrubber filtration system. This study aims to analyze the effect of varying the number of spray levels (one, two, and three levels) and water injection velocities (11.11, 16.37, and 23 m/s) on the velocity, pressure, and temperature of the gas flow inside the scrubber chamber. The approach utilized is a 3D computer simulation using Computational Fluid Dynamics (CFD). The results indicate that increasing the number of spray levels and water injection velocity leads to a highly turbulent and randomized gas flow pattern. The most optimal performance was achieved using a three level spray configuration with a water injection velocity of 23 m/s. Under these conditions, the high density of water droplets created a physical blockage effect, which accelerated the exhaust gas velocity to 7.395 m/s and sharply reduced the pressure at the outlet area. Furthermore, this high flow turbulence prolonged the contact time between the gas and water, successfully and drastically reducing the exhaust gas temperature from 325.37 K at the inlet area to 292.87 K at the outlet area.
