自然界有一种十分猛烈的旋风,叫做龙卷风。它卷有大量尘土,远看好像一根巨大的象鼻形云柱,高达数百米。实际上它是一团急速圜转、扶摇直上的空气漩涡,威力很大。在它所掠过的地方能拔树倒屋,吸起水柱,甚至重物也常常给卷上天,真是炎难之风。然而工程技术家却别出心裁地在各种工业装置中创造出与龙卷风相仿的旋风,用以达到许多技术目的。近十年来兴起一门动力工艺新技术——旋风技术,使许多工业生产过程发生了革命性的变化。 There is a very violent whirlwind in nature, called a tornado. It has a lot of dust and it looks like a giant elephant-like cloud column, up to several hundred meters. In fact, it is a whirlpool of air that spirals and swirls. It is very powerful. In the places where it passes by, trees can be pulled down, water columns can be sucked up, and even heavy objects can often be rolled up to the sky. This is really a difficult wind. However, the engineering technicians ingeniously created whirlwinds similar to tornadoes in various industrial installations to achieve many technical purposes. In the past ten years, a new technology of power technology, cyclone technology, has emerged, and many industrial production processes have undergone revolutionary changes.
