摘　　要：研究的负压降尘装置为文丘里管结构,通过设计多种内部结构不同的结构,以正交实验的方法,并以吸气量最大原则,优化了文丘里管的结构,得出了优化模型,并对优化后的模型进行了进一步的实验研究,得出了负压降尘装置吸气量与供水压力的关系。This paper researches on the negative pressure dust device consisted of a Venturi structure,and designs many different Venturi structures by changing the structure of the venture pipe.Through a series of contrast experiments,the paper optimizes the structure of the Venturi pipe according to the rule of maximize the inspiratory capacity and gets the best structure,then does some deep research on the optimized model to get the relationship between the inspiratory capacity and water pressure.

关 键 词：负压降尘 文丘里结构 吸气量 耗水量
