摘要： A filter module for use in filtering particulates from a high temperature gas has a central gas duct and at least one horizontally extending support mount affixed to the duct. The support mount supports a filter element thereon and has a chamber therein, which communicates with an inner space of the duct through an opening in the wall of the duct, and which communicates with the clean gas face of the filter element. The filter element is secured to the support mount over an opening in the top wall of the support mount, with releasable securement provided to enable replacement of the filter element when desired. Ceramic springs may be used in connection with the filter module either to secure a filter element to a support mount or to prevent delamination of the filter element during blowback.

摘要： Disclosed is an improved basket filter which minimizes raw material waste and is formed of at least one rectangular perforated metal foil part folded along a bending line at its middle, transversely to its longitudinal edge, and at least two perforated metal foil elements in the form of sectors of a circle. The longitudinal edges of the rectangular metal foil part are connected to the straight line edges of the metal foil elements in the form of sectors of a circle so that, after assembly, the filter defines a round opening which merges into a straight line bottom edge. Adjoining edges between the rectangular metal foil part and the straight line edges of the metal foil elements are embedded in a plastic.

摘要： A strainer is provided for removing particulate debris from a fluid passing therethrough. The strainer is primarily of the automatic type having a hollow body, a cover, a strainer element and a backwash arm assembly for cleaning the strainer element. The strainer element is a cylindrical, convoluted screen having encapsulating end caps positioned at either end. The end caps and thus the strainer element are retained so as to avoid rotation in seal rings, one of which is connected to the cover and the other of which is detachably connected to the terminus of the backwash arm. The strainer element is a structural member capable of withstanding the loads imposed on it by the fluid.

摘要： A coiled membrane filter cartridge includes a central pipe having at least one axial row of openings through which fluid may radially pass into or out of the pipe and two superposed membranes wound in a plurality of turns about the pipe to form a membrane coil having opposite axial ends. The membranes are radially spaced from one another for defining, between themselves, a spiral flow channel being sealed at the axial ends. A fluidtight partition extends between the membranes and is connected thereto. The partition divides longitudinally the spiral flow channel into axially adjoining partial channels.

摘要： The specification discloses a filter apparatus including spirally wound tissue layer filter elements for filtering fluid and a seal between the filter elements to prevent fluid from bypassing the filter elements. A flow tube extends through the center of the filter elements. A resiliently deformable mesh spacer is located on the flow tube between the filter elements to insure formation of a radial passageway therebetween. The seal is applied between the filter elements along their circumferential edges in a melted state and migrates into and between the tissue layers and interstices of the filter elements and the mesh of the spacer. As the seal cools and hardens it adheres to the filter elements and the spacer. A seal may likewise be applied between the filter elements and the flow tube. Application of the seals in this manner prevents fluid flow communication between the area outside of the filter elements and the radial passageway except by means of passage of fluid between the layers of tissue in the filter elements so that the filtering function is maximized.
摘要翻译： 本说明书公开了一种过滤装置，包括用于过滤流体的螺旋卷绕的组织层过滤元件和过滤元件之间的密封，以防止流体绕过过滤元件。 流管延伸穿过过滤元件的中心。 可弹性变形的网格间隔物位于过滤元件之间的流动管上，以确保其间形成径向通道。 密封件沿着其周边边缘以熔融状态施加在过滤器元件之间，并且迁移到过滤元件的组织层和间隙之间和间隔件的网格之间和之间。 当密封件冷却并硬化时，它粘附到过滤器元件和间隔件上。 同样可以在过滤元件和流管之间施加密封。 以这种方式施加密封件防止过滤器元件外部的区域与径向通道之间的流体流动连通，除了通过过滤元件中的组织层之间的流体通过，使得过滤功能最大化。
