The Applicatory Research Of Air-solid Compound Flow In The Separating And Dealing With City's Garbage

This article analyzes the present conditions of dealing with garbage in the interior and abroad in order to realize the reuing of garbage and reducing the amount of garbage, comprehensive process is one of the methods, and the technology of separating is the key of comprehensive process. However, in China, the effective method in dealing with the garbage is separating by wind force. The efficiency and extent are determined by the efficiency of processing by wind force. Grasping the distribution of all kinds of solid grains under the different wind velocities is of great importance in approving the efficiency of garbage separating by wind force.This article puts forward the physical and mathematical model by combination of E/E method and E/L method for continuous medium model and dispersed grain model in order to describe the grains flowing. The article also puts forward the initial prerequisite and boundary prerequisite and using the numerical value method to analyze the model above. It also disperses the equation by controlling the volume and using SIMPLER method to get the answer. At last we can get the distribution in the flow of separating space of different garbage grain under the different wind velocities.The design installs the experiment platform and carries on the experiment and it is identical to compare the answer with the data of the experiment. At last the experiment proves that it is accurate, reliable and universal to different imitate different grains flowing in air-solid compound by using this method.
