Venturi tube is one of key equipments in process of purification and recovery of converter gas which is used to drop temperature of converter gas with spraying jet fixed at throat of Venturi tube .

文氏 管 内部 的 流动 与 传热较为 复杂， 不仅涉及喷淋液滴与烟气在流动过程中的相互作用，而且涉及喷淋液滴遇到高温烟气发生相变进行的传热传质。

It is well known that the jet flow loses its pressure at the throat when the high spees mixture of gas and water passes the throat of venturi duster because the pressure loss at the throat has direct ratio with the square speed of the jet flow .

文丘里除尘器的压力损失主要是高速气水混合射流通过喉管而造成的，通过 喉管的压力损失与射流速度的平方成正比。
