Many industrial process like oil refining, food industry, mining and environmental cleanup are included separation of solid particles from gas stream. Vortex separators also called cyclone separators which are widely used in order to collect dust and particles from industrial gas flow that have been considered due to the simple structure, low operating space requirements and also the ability to function in harsh operating conditions. However, in the best operating conditions, it has not a desirable yield. Due to the cyclone’s function, several methods have been examined in order to increase its efficiency. One of the most effective methods is to use spiral concentrator. In this study, the goal is to evaluate the effect of the output clean gas embedded valve geometry in separation efficiency in spiral concentrator, which included some tests to survey effective parameters such as angle, length connection status and also primary and secondary flow. The results indicate that the efficiency of the concentrator has a direct connection to the length of the output valve and reverse connection to the angle. Thus, by increasing the output length and decreasing its angle the amount of absorbed dust is reduced, which indicate the rising of the concentrator’s efficiency. In this study, the highest achieved efficiency is 99.82%. This spiral concentrator can easily be used in industrial matters.
