Numerical Simulation of Square Section Venturi Scrubber with Horizontal Spray

In order to improve of tar removal efficiency of venturi tube, the authors synthetically analyzed a variety of tar removal methods, put forward square section venturi scrubber with horizontal spray for removing the tar from the gas, modeled the tube through the software CATIA, choosed the physical model, carried out the numerical simulation by the software ANSYS-FLUENT, and obtained the velocity contours, pressure contours and turbulent kinetic energy. The results show that the square section tube has such advantages as big velocity pulsation, big pressure loss, big turbulent kinetic energy and so on. And so it has a high efficiency of tar removal, and has a broad application prospect in engineering project.
