摘要： An improved composite material of high temperature and chemical resistant material and polytetrafluoroethylene (PTFE) is provided. The composite material incorporates a coherent strand of commingled filaments of fiberglass and PTFE which is far more resistant to flex, abrasion, and chemical attack than conventional materials. Preferably filaments of expanded PTFE tow yarn and filaments of PTFE are combined through a process of air-jet texturing. Fabrics made from the composite fibers are combined with thermosetting phenolic or epoxy resins to produce pleated cartridge filter elements exhibiting superior performance in high temperature and corrosive environments.

摘要： A filtering apparatus for separating particulate matter from a gas stream. The filtering apparatus has a pressure vessel defining an interior chamber having a dirty gas inlet opening and a clean gas exit opening. A tubesheet is coupled within the pressure vessel thereby dividing said pressure vessel into a dirty gas side and a clean gas side. A support pipe for supporting a plenum chamber within the pressure vessel dirty gas side is securely coupled with the tubesheet. The plenum chamber for supporting a plurality of filter elements is coupled to the support pipe. The plenum chamber has a side wall having at least one dirty gas port and clean gas exit formed therein. The side wall further defines a clean gas chamber. A plurality of filter element guides are securely coupled within the clean gas chamber for supporting at least one filter element and preventing filter elements from moving laterally. A removable dirty gas port coupler for providing a particulate barrier seal between the dirty gas port and the plenum clean gas chamber is provided. A filter element support plate for supporting a filter element within the clean gas chamber is securely coupled adjacent the dirty gas port. The filter element support plate has at least one slot which is aligned coaxially with at least one of the plenum chamber dirty gas ports.

摘要： Ceramic filter of various configuration have been used to filter particulates from hot gases exhausted from coal-fired systems. Prior ceramic cross-flow filters have been favored over other types, but those previously horn have been assemblies of parts somehow fastened together and consequently subject often to distortion or delamination on exposure hot gas in normal use. The present new monolithic, seamless, cross-flow ceramic filters, being of one-piece construction, are not prone to such failure. Further, these new products are made by novel casting process which involves the key steps of demolding the ceramic filter green body so that none of the fragile inner walls of the filter is cracked or broken.

摘要： In the filtering of high temperature (e.g. greater than 400.degree. C.) and high pressure (e.g. greater than 5 bar) gas--such as produced by pressurized fluidized bed combustion or gasification of coal--there is often a buildup of particles on the supporting elements for the filters, and on surrounding structures. This buildup of particles can damage the filter elements, or greatly reduce their effectiveness. This problem is avoided by periodically automatically cleaning the supporting and/or surrounding surfaces of the filters, as by directing high pressure gas streams at the supporting and/or surrounding surfaces. The filters may also be backflushed with compressed gas, as is conventional, at the same time as, or at different times than, when the supporting and/or surrounding structures are cleaned. Conduits with nozzles may be mounted directly on the supporting and/or surrounding surfaces and connected by a pipe with an automatically controlled valve to a source of high pressure fluid.
摘要翻译：在过滤高温（例如大于400℃）和高压（例如大于5巴）的气体（例如通过加压流化床燃烧或煤气化产生）中，通常在支撑物上堆积颗粒过滤器的元件和周围的结构。这种颗粒的积聚可能会损坏过滤元件，或大大降低其效果。通过周期性地自动清洁过滤器的支撑和/或周围表面来避免这个问题，如通过在支撑和/或周围表面处引导高压气体流。过滤器也可以用压缩气体反冲洗，如常规的那样，在支撑和/或周围结构被清洁的同时或不同的时间。带有喷嘴的管道可以直接安装在支撑和/或周围表面上，并通过具有自动控制阀的管道连接到高压流体源。
