摘要： An improved wet scrubber tray provides increased resistance to vibration-induced cracking. The tray is self supporting to eliminate wastage of raw material, and additional internal stiffeners added to the tray make multiple intermediate stiffeners. The connection of the intermediate stiffeners to the perforated bottom plate is changed to eliminate the shop weld in the bottom plate. The holes in the perforated bottom plate are repositioned so that they are moved away from the boundaries of the tray to reduce their influence on boundary conditions. The thickness of the tray material may be increased to lower the vibratory stresses. The mechanism for holding the trays themselves within the spray absorber tower is changed so that the trays are now held down by plate material that is attached to the support grid, but not to the trays. Three field welds are applied to the sides of each tray to hold the trays in place relative to each other and are strategically placed to allow adjacent side stiffeners to act together as a composite section, thus increasing their strength. Elastomeric material such as neoprene is used at the tray-to-grid attachments to increase the damping of the system. Formed features in the trays such as single or multiple ribs, bosses, domes or dimples may also be provided to increase tray stiffness or influence wet scrubber performance.
摘要翻译： 改进的湿式洗涤塔提供增加的抗振动引起的开裂的阻力。 托盘自支撑以消除原材料的浪费，并且添加到托盘中的额外的内部加强件形成多个中间加强件。 改变中间加强筋与多孔底板的连接，以消除底板中的车间焊接。 穿孔底板中的孔重新定位，使得它们远离托盘的边界移动以减小它们对边界条件的影响。 可以增加托盘材料的厚度以降低振动应力。 将托盘本身保持在喷雾吸收塔内的机构被改变，使得托盘现在被固定在支撑格栅上而不是托盘的板材夹紧。 三个焊缝被施加到每个托盘的侧面以将托盘相对于彼此保持在适当的位置，并且被有策略地放置以允许相邻的侧加强件一起作为复合部分起作用，从而增加它们的强度。 弹性材料如氯丁橡胶用于托盘到栅格附件以增加系统的阻尼。 还可以提供托盘中形成的特征，例如单个或多个肋，凸台，圆顶或凹坑以增加托盘刚度或影响湿式洗涤器的性能。

摘要： A self supporting header has a horizontally extending header pipe of fiberglass reinforced plastic with a horizontal axis and a flange of fiberglass reinforced plastic connected to an outer surface of the header pipe by at least one web and extending along at least part of the horizontal extent of the header pipe. The at least one web extends vertically from at least one of the top and bottom of the header pipe and is connected to the flange. A reinforcing member or material is embedded in at least one of the flange and the at least one web and that has a greater modulus of elasticity than a modulus of elasticity of the fiberglass reinforced plastic of the header pipe reinforces a cross-section of the header for increasing the self supporting strength of the header. The reinforcing member may be made of metal or a carbon composite material.
