摘要

A cold state device of a composite spray quench chamber was established. In order to obtain the distribution of atomized droplet sizes at radial and axial positions along the flow field, different combinations of multi-spray nozzles were selected. The atomized droplet size along the axial position was measured using a Malvern Spraytec under different conditions. The results showed that Sauter Mean Diameter (SMD) D-32 near the nozzles was mainly influenced by liquid flow rate. However, D-32 further away from the nozzles was affected by both liquid and gas flow rate. Along the axial direction, with increasing of the relative height (h/H), D-32 decreased. D-32 around the gas outlet was mainly affected by the gas flow rate, growing from 80 to 160 mu m as the gas flow rate increased from 0.29 to 0.49 m - s(-1), which was similar to the calculated data. The research can optimize and improve the internal structure of a spray quench chamber, providing guidance to industrial applications.
