Effects of Particle Properties on Decomposition Performance in Ultrasonic Airlift Reactor
The ultrasonic airlift reactor is proposed for the treatment of wastewater including some soil particles in addition to the refractory materials. The reactor is a bubble column with a draft tube and with an ultrasonic oscillator attached at the bottom of the column. The particles are spherical silica and alumina. The concentration and diameter of particle, the gas velocity and draft tube diameter are changed, and the decomposition conversion is examined. As particle concentration becomes higher, the decomposition conversion decreases. The decrement in decomposition conversion is affected by the particle material. With increasing gas velocity and draft tube diameter, the decomposition conversion increases. The increment in gas holdup can compensate the decrement in decomposition performance with particle addition.
