移动—流化型组合阀工作特性的研究

A Study Concerning the Test of the Operating Characteristics of a Shifting-fluidized type of Combination Valve and Its Model

移动—流化型组合阀是一种输送固体颗粒物料的新型非机械阀 ,影响其工作特性的关键技术是移动床底部松动风的设置。

A shifting-fluidized type of combination valve is a kind of novel non-mechanical valve for transporting solid-particle raw materials. The key technique affecting its operating characteristics involves the provision of a sort of slackening air at the bottom of the shifting bed. The present paper mainly focuses on an experimental investigation regarding the provision of the slackening air device and a mathematical model for calculating raw material flow rate.
