摘要： A lance-type spraying assembly for directing a reducing agent into a combustion zone or discharging combustion gases for Nox emission control. The spraying assembly including a lance body having an inlet end and a downstream end and a spray nozzle arranged at the downstream end of the lance body. The lance body includes an air passage for connection to an air supply, a liquid reducing agent supply passage for connection to a liquid reducing agent supply and a liquid reducing agent return passage. The liquid reducing agent supply passage communicates with the spray nozzle. The liquid reducing agent return passage communicates with the liquid reducing agent supply passage near the downstream end of the lance body for recirculating a portion of the liquid reducing agent and extends near the liquid reducing agent supply passage along at least a portion of the length thereof in order to help cool the liquid reducing agent therein. The liquid reducing agent return passage is sealed against the spray nozzle. The air passage extends near at least a portion of the liquid reducing agent supply passage in order to help cool the liquid reducing agent therein.

摘要： A spray nozzle assembly that utilizes ultrasonic atomization techniques to atomize a liquid into a cloud of small or fine droplets is disclosed. The nozzle assembly also can use various air or gas atomizing technologies to propel the generally directionless droplet cloud toward a surface or substrate to be coated. The propelled droplet cloud may at this state have a conical or cone-shaped spray pattern. Additional air or gas atomizing technologies can be utilized to shape the propelled droplet cloud into a flattened fan-shaped spray pattern that can be usable in various industrial applications. The shape of the spray pattern and the distribution of droplets within the pattern can be adjusted by manipulation of the gas pressure used in gas atomization.
摘要翻译：公开了一种喷雾喷嘴组件，其利用超声雾化技术将液体雾化成小云滴或小雾滴。喷嘴组件还可以使用各种空气或气体雾化技术将大致无方向的液滴云推向待涂覆的表面或基底。推进的液滴云可以在这种状态下具有圆锥形或锥形喷雾模式。可利用额外的空气或气体雾化技术将推进的液滴云变成扁平的扇形喷雾图案，其可用于各种工业应用中。可以通过操纵气体雾化中使用的气体压力来调节喷雾图案的形状和图案内的液滴分布。

摘要： A nozzle assembly that produces a cone-shaped spray pattern of entrained liquid droplets is disclosed. The nozzle includes an ultrasonic atomizer for atomizing a liquid on an atomizing surface located at the end of an atomizing stem. The nozzle assembly is supplied pressurized air that is directed to the atomizing surface by intercommunicating ports, chambers and/or channels. To provide the cone-shaped spray pattern, the ports, chambers and/or channels cause or direct the pressurized gas to rotate about the atomizing stem. When the rotating pressurized gas exits the nozzle assembly via proximate the atomizing surface, atomized liquid droplets become entrained in the gas. The rotating pressurized gas propels the droplets forward and moves at least some droplets circumferentially outward in the cone-shaped spray pattern. In various embodiments, the pressure of the gas can be adjusted to control the size and shape of the cone-shaped pattern and the distribution of droplets.
摘要翻译：公开了一种产生夹带液滴的锥形喷雾图案的喷嘴组件。喷嘴包括用于雾化位于雾化杆端部的雾化表面上的液体的超声雾化器。喷嘴组件被供应通过相互连通的端口，室和/或通道引导到雾化表面的加压空气。为了提供锥形喷射图案，端口，室和/或通道使加压气体围绕雾化杆旋转或引导。当旋转的加压气体通过靠近雾化表面离开喷嘴组件时，雾化的液滴就被夹带在气体中。旋转的加压气体向前推动液滴并且以锥形喷射图案周向向外移动至少一些液滴。在各种实施例中，可以调节气体的压力以控制锥形图案的尺寸和形状以及液滴的分布。
