摘      要：As an innovative thermal energy technology,the spray-type packed bed has advantages of high efficiency and low cost.A liquid distributor is the key component for the spray-type packed bed for scattering heat-transfer liquid drops *** this study,the distribution performance and pressure drop of the perforated plate distributors of different orifice diameters were studied *** experimental results indicate that orifice diameter has a greater effect on the distribution performance compared to flow *** an increase in flow rate,the flow pattern through the distributor changes from the uncovered drop to the covered drop and then to the jet *** covered drop pattern shows the best performance with a good distribution and a small pressure drop simultaneously,which is the design and optimization principle of the distributor for a spray-type packed bed.
