摘要:
A packing material for liquid/gas contact reaction apparatus, in particular for gas purifying systems, which consists of a plurality of parallel rods arranged on a basket-shaped carrier and so dimensioned that it has an approximately spherical or spheroid form. The carrier consists preferably of parallel rings of staggered diameters. The packing material according to the invention has an extraordinarily high degree of efficiency and is very easy and relatively cheap to manufacture.

In a method of manufacturing objects, extrudable ceramic forming material is extruded through multiple dies arrayed around an extrusion axis, the dies mounted to permit controlled movement of the dies during the course of extrusion to vary the position of several extrudate streams exiting the dies. Extruded objects are defined by spokes corresponding to the extrudate streams with the streams having a varying spacing from a central axis.

A catalyst carrier may have a cross-sectional shape that may include a plurality of surface channels having a first channel width and a second channel width, where the first channel width may be closer to a periphery of the cross-sectional shape than the second channel width and the first channel width may be less than the second channel width. The cross-sectional shape may further include a plurality of surface features where at least one surface feature is located between at least one pair of surface channels. The cross-sectional shape may further include a ratio LOC/LSCP of at least about 1.7, where LOC is a length of a total contour of the cross-sectional shape and LSCP is a length of an outer simple convex perimeter of the cross-sectional shape.

A filter device for filtering dust from air includes a housing, a dust collecting module, a spraying module, and an exhaust. The housing defines an air inlet near a bottom of the housing and an air outlet near a top of the housing. The dust collecting module is installed in the housing between the air inlet and the air outlet. The spraying module is placed in the housing between the dust collecting module and the air outlet. The exhaust is connected to the housing for generating air pressure difference between near the air outlet and near the air inlet, thereby drawing and introducing air containing dust from the bottom of the housing toward the top of the housing via the air inlet.
摘要:
A saddle-shaped random packing element is provided with laterally spaced, arcuate side members and a plurality of inner and outer rib elements that extend from and between the side members to form an interior volume. At least one lesser rib element extends from the side members and is at least partially positioned within the interior volume so that at least about 20 percent of the surface area of the packing element is positioned within the interior volume.

An improved random packing is the subject of the present invention. The packing element comprises a generally spherically shaped member which can be a perfect sphere, an ellipse, or some variation on either of the foregoing. The sphere is a hollow body having inner and outer surfaces with a plurality of openings passing through the body. A hypothetical axis passing through the sphere defines circular openings at both ends and the openings in between these two ends are generally elongated. The solid walls which form the sphere are of sufficient thickness so as to accommodate a plurality of indentations, some of which are formed in the solid walls and other indentations being formed coincidentally with the elongated openings between the solid wall sections. The indentations are characterized by curvilinear surfaces so that the total surface area presented by the inner surface (S1) and all of the remaining surfaces (S2) are at least twice the area of solid sphere of the same diameter with no indentations.

Novel catalyst beds comprising a physical mixture of catalytically active and catalytically inactive shaped bodies, in which the catalytically inactive shaped bodies have rounded edges on the external rubbing surfaces.
摘要:
A process for selecting shaped particles for use in a tube which is capable of being packed with shaped particles to form a packed bed in the tube. A desired value of one or more properties of the packed bed is defined. The dimensions of the shaped particles are calculated such that a packed bed in the tube of the shaped particles having the calculated dimensions meets or substantially meets the desired value(s), and shaped particles are selected in accordance with the calculated dimensions. The properties of the packed bed may be the volume fraction which is occupied by shaped particles, the packing density, and the resistivity for a gas flowing through the packed bed.
