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.

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： An improved cross flow ceramic filter is disclosed for utilization in high temperature, high pressure applications such as found in hot gas cleaning in coal based power generation. The cross flow ceramic filter of the present invention includes a plurality of identical corrugated sheets composed of chopped ceramic fiber matrix material and a plurality of predetermined sized end blocks shaped to fill the cross section passageways formed between the partly spaced corrugations of adjacent sheets of the filter material. One advantage of the corrugated sheet cross flow filter of the present invention is that the filter may be shipped to its site in semi-cured form unassembled. When the filter is received on site, the corrugated sheets are partially separated from each other until passageways of the desired dimension are achieved. Thereafter, the end blocks and glue may be applied between the blocks and the ends of the corrugated sheets and between the apexes of the corrugations where the corrugated sheets overlap. A final cure for the filter may be made with the filter in place in the filter vessel utilizing high temperature, high pressure flue or fuel gas on site.
摘要翻译： 公开了一种改进的横流陶瓷过滤器，用于高温，高压应用中，例如在煤基发电中的热气体清洗中发现的。 本发明的交叉流动陶瓷过滤器包括多个相同的波纹板，其由切碎的陶瓷纤维基质材料和多个预定尺寸的端块组成，多个预定尺寸的端块被成形为填充形成在相邻过滤器片的部分间隔的波纹之间的横截面通道 材料。 本发明的波纹片交叉流过滤器的一个优点是过滤器可以以未组装的半固化形式运送到其位置。 当现场接收过滤器时，波纹片彼此部分分离，直到达到所需尺寸的通道。 此后，端块和胶可以施加在块和波纹片的端部之间以及波纹片重叠的波纹的顶点之间。 过滤器的最终固化可以通过过滤器在现场使用高温高压烟道或燃料气体的过滤器中进行。

摘要： An improved filter candle is provided for filtering entrained particulate matter from hot gasses. The filter candle is constructed ceramic fibers bonded together into a porous unitary tubular mask having a bottom end and an annular flange at the top end. The top and bottom ends of the filter have substantially higher density than the tubular mid-section of the filter and as a result, the strength of the end portions of the filter is enhanced, and the ends are therefore less susceptible to damage.

摘要： A ceramic filter candle is formed by a skeleton of ceramic fibers and spaced apart metallic perforate reinforcing members bonded together by means of a ceramic binder and a porous ceramic coating material which partially fills the interstices between the fibers and the perforations in the reinforcing members. The candle is manufactured in a vacuum forming process wherein an aqueous slurry of the ceramic fibers and a ceramic binder is drawn through a generally cylindrical mold surface and the preformed tubular reinforcing members to deposit the fibers on the mold surface and over the reinforcing members. The fibers and the reinforcing members are subsequently coated with a ceramic material.
