当前国外使用的喷雾器种类颇多,但归纳起来不外乎三大类。即以水为工作液,按机械动作原理设计的水喷雾器,目前已发展为标准喷雾器;以压气和水为工作液,按压气雾化液体的原理设计的压气喷雾器,亦称气水喷雾器;根据文丘里原理设计的引射器,通过引射器外壳引进并排出大量空气进一步雾化液体。兹将这些喷雾降尘装置的结构原理及效果对比分别介绍如下。
At present, there are quite a few sprays used abroad, but there are no more than three categories. That is, water as the working fluid, designed according to the principle of mechanical action water sprayer, has now developed into a standard sprayer; to gas and water as the working fluid, press the principle of aerosolized liquid designed pressure sprayer, also known as gas water sprayer; according to Venturi principle designed ejector, the introduction of the ejector housing and exhaust a large amount of air to further atomize the liquid. The structure of these spray dustfall device structure and effect comparison are as follows respectively.
