摘要: A filter suitable for the filtration of high temperature gasses includes a high pressure tank enclosing a chamber divided into a plurality of separate chambers by horizontally disposed rigid tube sheets. A plurality of banks of filter tubes are positioned in mutual alignment between adjacent ones of the tube sheets. Guide channels are provided on the tops and bottoms of the tube sheets for sealably mounting the filter tubes in place between the tube sheets. Fluid outlets open to the ambient through the wall of the tank between each adjacent pair of tube sheets and covers are removably secured over openings in the wall of the tank for access to the filter tubes.

摘要: A process for filtering fine particulates from a stream of hot gas wherein the particulates vary in size between about 0.15 and 250 microns includes the steps of removing a majority of the larger size particles from the gas stream, while leaving a majority of the smaller particles in the stream, then introducing into the gas stream particulates having an average size greater than the smaller size particulates, and thereafter passing the gas stream through a porous filter medium having a pore size exceeding the size of the smaller size particulates.

摘要: An improved hot gas filter candle is disclosed including an increase density flange portion adjacent the top of the filter for improving candle service life when the candle is mounted on a tube sheet. The area of flange densification is extended to a position beyond the bottom of the tube sheet. During vibration or swaying of the candle only the denser portion of the candle may impinge on the edge of the tube sheet aperture on which the candle is mounted Further, the denser portion of the candle is not so porous as to draw dirty particles into the clearance between the candle and the tube sheet aperture creating an area of increased stress in the candle adjacent the bottom of the tube sheet aperture.

摘要: A composite filter element for filtering hot gasses is made up of a porous ceramic core to which a porous ceramic, thin outer layer is integrally bonded. The outer layer has a mean pore size which is at least several times smaller than the mean pore size of the substrate and the substrate is at least several times thicker than is the outer layer. The outer layer and the substrate are preferably formed of the same material or of two different materials having essentially the same coefficient of thermal expansion.

摘要: Apparatus for filtering a fluid or gas stream under pressure includes a tank having inlet and outlet ports with a tube sheet disposed therebetween. The tube sheet supports one or more generally elongate filter tubes disposed in tube sheet apertures arranged in spaced relation one to another. Each filter tube has a flange which is sealed to the tube sheet by an annular gasket which expands as its temperature rises. The tube sheet is provided with upstanding circular wall members circumscribing the filter tube apertures. The inside diameter of the wall members is larger than the outside diameter of the filter tube flange forming a recess within which the flange is receivable. A plurality of through holes in the wall members receive pins extending across the filter tube flanges.

摘要: A unitary candle filter employs a wrapping of continuous filamentary ceramic material in the form of a yarn or twine wrapped over a porous ceramic support tube to hold the support structure intact during a high pressure backwash operation. A thin filtering layer of a ceramic material is deposited over the support structure and the wrapping is embedded in the filtering layer.
