摘要： A steam distributor (1) that uses a porous metal plate to replace the conventional screen plate (3) of a steam shower for distributing steam to a moving web (2) such as the web of a paper making machine. Steam showers using a steam distributor with this porous metal plate can deliver extremely uniform steam to the surface of a paper web. Profiling steam showers constructed by using an array of the steam distributors are able to deliver the best profiling results for various paper products. The porous metal plate can be considered as an equivalent of a screen plate with thousands of micro-orifices arranged tightly in both the machine direction and the CD direction.
摘要翻译：一种蒸汽分配器（1），其使用多孔金属板来代替用于将蒸汽分配到诸如造纸机的幅材的移动幅材（2）的蒸汽淋浴器的常规筛板（3）。使用这种多孔金属板的蒸汽分配器的蒸汽淋浴器可以向纸幅表面提供非常均匀的蒸汽。通过使用蒸汽分配器阵列构造的蒸汽淋浴能够为各种纸制品提供最佳的成型结果。多孔金属板可以被认为是与机器方向和CD方向上紧密配置的数千个微孔的筛板相当的。

摘要： An apparatus and method to use steam to atomize water to produce a mixture of moisture and heat for application to the web of a paper machine for both production improvement and paper quality control. The method allows independent droplet size and heat control in the mixture, resulting in flexibility that can not be offered by conventional steam showers or water spray systems individually. In one embodiment the apparatus consists of a plurality of actuator nozzle modules (10) which control the water volume flow feeding the nozzle (22) through a pneumatic pressure signal. Pressurized steam feeding the nozzle (22) is used to break the water into fine droplets. The resulting nozzle spray is a mixture of moisture in fine water droplets and steam vapor, and heat stored in the steam. Alternatively, a plurality of steam valves can be used to regulate the steam volume flow feeding each atomizing nozzle.
摘要翻译：一种使用蒸汽来雾化水以产生水分和热量的混合物的装置和方法，以用于造纸机的卷筒纸，用于生产改进和纸张质量控制。该方法允许混合物中独立的液滴尺寸和热控制，导致常规蒸汽淋浴或喷水系统不能单独提供的灵活性。在一个实施例中，该装置由多个致动器喷嘴模块（10）组成，致动器喷嘴模块（10）通过气动压力信号来控制供给喷嘴（22）的水量。用于将喷嘴（22）供给的加压蒸汽用于将水分解成细小的液滴。所得到的喷嘴喷雾是在细小的水滴和蒸气蒸气中的水分的混合物，并且储存在蒸汽中的热量。或者，可以使用多个蒸汽阀来调节供给每个雾化喷嘴的蒸汽体积流量。
