摘要： A process for converting silicon intermediates to high purity silicon by an arc heater characterized by the steps of preliminarily reacting gaseous silicon intermediate, such as a silicon halide, with a metal reductant, such as sodium, to form preliminary reaction products including small solid silicon particles and droplets of salt of the metal reductant, at temperatures below the boiling point of the metal reductant, subsequently heating the reaction products to temperatures above said boiling point in an arc heater chamber to convert the reaction products to droplets of silicon to merge and form larger silicon droplets, and thereafter separating the mixture of silicon droplets and salt vapor.

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： A filter system wherein a hollow tubular member having an imperforate wall with a plurality of slots therein is coaxially positioned within a perforated mandrel that supports a ceramic bag filter. Gases to be filtered pass through the bag filter and deposit particulate matter thereon, enter a chamber between the perforated mandrel and the hollow tubular member, and are directed through the slots into the interior of, and are discharged from an open end of the hollow tubular member. Vapor phase contaminants in the gas can also be removed by providing a bed of solid absorbent material in the hollow tubular member such that the gas contacts the solid absorbent material and the vapor phase contaminant is removed prior to discharge of the gas from the open end of the hollow tubular member.

摘要： A filtering unit for filtering particulates from high temperature gases uses a spiral ceramic spring to bias a ceramic, tubular filter element into sealing contact with a flange about an aperture of a metallic tube sheet. The ceramic spiral spring may contact the upper edge of the filter element and be restrained by a stop member spaced from one end of the tube sheet, or the spring may contact the bottom of the filter element and be restrained by a support member spaced from the opposite end of the tube sheet. The stop member and support member are adjustably secured to the tube sheet. A filtering system uses the ceramic spiral spring to bias a plurality of ceramic, tubular filter elements in a respective plurality of apertures in a tube sheet which divides a vessel into upper and lower enclosed sections.

摘要： A filter cleaning process for filters for separating particulates from a hot gas stream using hollow, tubular filter elements. Blowback and hot purge gas systems provide for cleaning of the filter elements and maintenance of the blowback system clear of the solids or condensation products that might form during separation. The process is especially useful in filtering solids from a hot, corrosive gaseous stream, such as a zirconium tetrachloride process gaseous stream, where the gas stream contains gaseous constituents that are subject to condensation directly to a solid during separation of the particulates and prior to discharge from the filtering apparatus.

摘要： A filtering apparatus for separating particulates from a hot gas stream using hollow, tubular filter elements has a housing with a laterally extending support plate for the filter elements separating the housing into upper and lower sections. The tops of the filter elements are biased against the support plate and the bottoms thereof restrained from lateral movement by restraining rings. Blowback and purge gas systems provide for cleaning of the filter elements and maintenance of the blowback system clear of the solids or condensation products that might form during the separation. The apparatus is especially useful in filtering solids from a hot, corrosive gaseous stream, such as a zirconium tetrachloride process gas stream, where the gas stream contains gaseous constituents that are subject to condensation or solids formation during separation of the particulates and prior to discharge from the filtering apparatus.
