本發明係關於一種陶纖濾管強化方法及強化陶纖濾管，尤其是一種可以提升抗壓強度的陶纖濾管強化方法及強化陶纖濾管。 The invention relates to a ceramic fiber filter strengthening method and a reinforced ceramic fiber filter tube, in particular to a ceramic fiber filter tube strengthening method capable of improving compressive strength and a reinforced ceramic fiber filter tube.
一般而言，陶纖濾管係由陶瓷纖維構成之管狀過濾元件，由於其具有高孔隙率及耐高溫之特性，故可以用於工業高溫廢氣之過濾，例如用於過濾工業燃燒所排放之廢氣。於使用時，係將陶纖濾管安裝於過濾器中，而過濾器之一端連接抽風裝置，藉由抽風裝置降低陶纖濾管內部之壓力，而將廢氣自陶纖濾管之外部吸入內部，使廢氣中所包含之灰塵被隔絕於陶纖濾管之外壁，而達成過濾效果。經過一段時間之使用後，灰塵會累積於陶纖濾管之外壁而形成塵餅，此時則藉由過濾器系統之清洗裝置產生一反向脈衝氣流，吹入陶纖濾管內，以使外部塵餅自陶纖濾管之外壁剝離脫落而被其下之料斗所收集。 In general, the ceramic fiber filter tube is a tubular filter element made of ceramic fiber.

In use, the ceramic fiber filter tube is installed in the filter, and one end of the filter is connected to the air suction device, and the pressure inside the ceramic fiber filter tube is lowered by the air suction device, and the exhaust gas is taken into the interior from the outside of the ceramic fiber filter tube. The dust contained in the exhaust gas is isolated from the outer wall of the ceramic fiber filter tube to achieve a filtering effect. After a period of use, dust accumulates on the outer wall of the ceramic fiber filter tube to form a dust cake. At this time, a reverse pulse gas flow is generated by the cleaning device of the filter system, and is blown into the ceramic fiber filter tube, so that The outer dust cake is peeled off from the outer wall of the ceramic fiber filter tube and collected by the hopper below it.
然而，由於陶瓷纖維本身的脆性高，且陶纖濾管具有高孔隙率之特性，故其強度較低，可能於受到外力作用時於夾持端或其他受力端碎裂崩解，造成使用不便，須經常更換而增加使用成本。有鑑於此，有必要提供一種陶纖濾管的強化方法及強化陶纖濾管，以解決上述問題。 However, due to the high brittleness of the ceramic fiber itself and the high porosity of the ceramic fiber filter tube, the strength of the ceramic fiber filter is low, and may be broken and disintegrated at the clamping end or other force end when subjected to an external force, resulting in use.

本發明之強化陶纖濾管，係以上述之陶纖濾管強化方法製成。由於該硬化劑僅吸附於該強化陶纖濾管之開口段及封閉段，未吸附於 該延伸段，故不會影響該強化陶纖濾管之過濾能力，達成「提升該強化陶纖濾管之過濾效能」功效。 The reinforced ceramic fiber filter tube of the present invention is produced by the above-mentioned ceramic fiber filter tube strengthening method.

為讓本發明之上述及其他目的、特徵及優點能更明顯易懂，下文特舉本發明之較佳實施例，並配合所附圖式，作詳細說明如下：本發明之陶纖濾管強化方法，包含提供一陶纖濾管及一硬化劑，該陶纖濾管具有相連之開口段、延伸段及封閉段，使該硬化劑吸附於該陶纖濾管之開口段及封閉段，續固化該硬化劑。 The above and other objects, features and advantages of the present invention will become more <RTIgt; The method comprises the steps of: providing a ceramic fiber filter tube and a hardening agent, wherein the ceramic fiber filter tube has a connected open section, an extended section and a closed section, so that the hardener is adsorbed on the open section and the closed section of the ceramic fiber filter tube, and continued The hardener is cured.
請參照第1圖，該陶纖濾管通常具有均勻之孔隙率，例如具有70~85%之孔隙率。此外，該陶纖濾管可以以任何種類之陶纖纖維製成，且另可以混合其他纖維或材質，亦可以包含觸媒。該陶纖濾管可以區分為一開口段1、一延伸段2及一封閉段3，該延伸段2連接於該開口段1及該封閉段3之間。該開口段1即為法蘭(flange)之位置，該開口段1設有一開口11，該開口11之外周緣可以設有一凸緣12，用以連接抽風裝置或管線或夾板等。該封閉段3則為一封閉狀之尾端，該開口段1、該延伸段2及該封閉段3之比例可以為10~20：260~280：10~20。於本實施例中， 該陶纖濾管之總長係為300cm，該開口段1及封閉段3之長度皆為10~15cm，而該延伸段2之長度則為270~280cm。 Referring to Figure 1, the ceramic fiber filter generally has a uniform porosity, for example, having a porosity of 70 to 85%. In addition, the ceramic fiber filter tube can be made of any kind of ceramic fiber, and can be mixed with other fibers or materials, and can also contain a catalyst. The ceramic fiber filter tube can be divided into an open section 1, an extended section 2 and a closed section 3, and the extended section 2 is connected between the open section 1 and the closed section 3. The open section 1 is the position of a flange. The open section 1 is provided with an opening 11. The outer periphery of the opening 11 may be provided with a flange 12 for connecting a draft device or a pipeline or a splint or the like. The closed section 3 is a closed tail end, and the ratio of the open section 1, the extended section 2 and the closed section 3 may be 10-20:260~280:10~20. In this embodiment, The length of the ceramic fiber filter tube is 300 cm, and the length of the open section 1 and the closed section 3 are 10-15 cm, and the length of the extension 2 is 270-280 cm.
該硬化劑可以為樹脂或矽溶膠(colloidal silica)等高分子材料，其可以固化並提供較高之硬度者，且該硬化劑之選擇可以依據該陶纖濾管之使用需求而調整。舉例而言，若該陶纖濾管係應用於高溫環境，則該硬化劑較佳為耐高溫之樹脂或矽溶膠；若該陶纖濾管係應用於酸性廢氣之過濾，則較佳選擇耐酸之樹脂或矽溶膠。於本實施例中，係選用矽溶膠作為該硬化劑，其具有耐高溫、耐酸之特性，該矽溶膠係包含以重量百分比計為20~60%之二氧化矽，或者，該矽溶膠可以包含30~50%之二氧化矽。 The hardener may be a polymer material such as a resin or a colloidal silica, which can be cured and provides a higher hardness, and the choice of the hardener can be adjusted according to the use requirements of the ceramic fiber filter. For example, if the ceramic fiber filter tube is applied to a high temperature environment, the hardener is preferably a high temperature resistant resin or a ruthenium sol; if the ceramic fiber filter tube is applied to the filtration of acid waste gas, the acid resistance is preferably selected. Resin or bismuth sol. In the present embodiment, a cerium sol is selected as the hardening agent, which has high temperature resistance and acid resistance, and the cerium sol contains 20 to 60% by weight of cerium oxide, or the cerium sol may contain 30~50% of cerium oxide.
使該硬化劑吸附於該陶纖濾管之開口段及封閉段的方法，可以為浸泡、沖淋或噴塗等，本發明不加以限制，惟較佳係使該硬化劑可以滲透進入該開口段及封閉段之孔洞中，進而可以使該開口段及封閉段分別具有均勻之強度。舉例而言，係可以將該開口段及封閉段分別浸泡於該硬化劑中1~4次，每次浸泡10~60秒，以使該硬化劑得以滲入並均勻吸附於該陶纖濾管之孔洞中，以提升強化效果。 The method of adsorbing the hardener to the open section and the closed section of the ceramic fiber filter tube may be immersion, showering or spraying, etc., and the invention is not limited, but preferably, the hardener can penetrate into the open section. And in the hole of the closed section, the open section and the closed section can be respectively made to have uniform strength. For example, the open section and the closed section may be respectively immersed in the hardener for 1 to 4 times, each soaking for 10 to 60 seconds, so that the hardener can be infiltrated and uniformly adsorbed to the ceramic fiber filter tube. In the hole, to enhance the strengthening effect.
固化吸附於該陶纖濾管之硬化劑的方法，係可以依據該硬化劑之性質選擇。例如，若使用矽溶膠，則可以進行烘烤或於室溫下風乾之方式進行固化；若選用紫外光硬化型樹脂，則可以照射紫外光，以使該硬化劑固化。由於陶纖濾管多為不可透光之材質，故較佳係選用熱固化類型之硬化劑，並藉由烘烤之方式進行固化，而可以避免部分硬化劑未固化之情形發生。以矽溶膠為例，係可以於100~150℃之溫度下加熱2~7小時，以確保該硬化劑可以完全固化。於本實施例中，係以120℃之溫度加熱4小時，以使矽溶膠完全固化。此處需注意的是，因應不同的使用需求，該開口段及封閉段的長度、硬化劑選擇、硬化劑吸附方式及固化條件皆可以 分別調整之，而無需使該開口段及該封閉段之條件相同。 The method of curing the hardener adsorbed to the ceramic fiber filter tube can be selected according to the nature of the hardener. For example, if a cerium sol is used, it may be baked or air-dried at room temperature; if an ultraviolet curing resin is used, ultraviolet light may be irradiated to cure the hardening agent. Since the ceramic fiber filter tube is mostly a material that is not permeable to light, it is preferred to use a heat curing type hardener and cure by baking, thereby avoiding the occurrence of partial hardening of the hardener. For example, the cerium sol can be heated at a temperature of 100 to 150 ° C for 2 to 7 hours to ensure that the hardener can be completely cured. In the present embodiment, it was heated at a temperature of 120 ° C for 4 hours to completely cure the cerium sol. It should be noted here that the length of the open section and the closed section, the choice of hardener, the adsorption mode of the hardener and the curing conditions can be varied according to different use requirements. Adjusted separately without the conditions of the open section and the closed section being the same.
待吸附於該陶纖濾管之硬化劑完全固化後，即製得本發明之強化陶纖濾管。由於該硬化劑僅填充於該強化陶纖濾管之開口段及封閉段，因此，該強化陶纖濾管之延伸段的孔隙率仍可維持原有較高之孔隙率而可以大於該開口段及封閉段之孔隙率。舉例而言，該陶纖濾管之延伸段的孔隙率可以為70~85%，而該開口段及封閉段之孔隙率可以為0~60%。於本實施例中，該強化陶纖濾管之延伸段的孔隙率係為72%，該開口段及封閉段之孔隙率則為51%，而可以使該強化陶纖濾管之整體強度較高，同時仍維持良好的過濾效能。再者，因應使用需求，該開口段及封閉段的孔隙率可以不同。 After the hardener adsorbed to the ceramic fiber filter tube is completely cured, the reinforced ceramic fiber filter tube of the present invention is obtained. Since the hardener is only filled in the open section and the closed section of the reinforced ceramic fiber filter tube, the porosity of the extended section of the reinforced ceramic fiber filter tube can maintain the original high porosity and can be larger than the open section And the porosity of the closed section. For example, the extension of the ceramic fiber filter tube may have a porosity of 70 to 85%, and the porosity of the open section and the closed section may be 0 to 60%. In this embodiment, the porosity of the extended section of the reinforced ceramic fiber filter tube is 72%, and the porosity of the open section and the closed section is 51%, and the overall strength of the reinforced ceramic fiber filter tube can be made. High while still maintaining good filtration performance. Furthermore, the porosity of the open section and the closed section may be different depending on the demand for use.
使用該強化陶纖濾管時，係將該開口直接或間接連接抽風裝置，藉由抽風裝置降低該強化陶纖濾管內部之壓力，而將廢氣自其外部吸入內部，使廢氣中所包含之灰塵被隔絕於該強化陶纖濾管之外壁而達成過濾效果。經過一段時間之使用後，灰塵會累積於該強化陶纖濾管之外壁而形成塵餅，此時則藉由系統之反吹裝置產生一反向脈衝氣流，以使塵餅自該強化陶纖濾管之表面脫落。 When the reinforced ceramic fiber filter tube is used, the opening is directly or indirectly connected to the air suction device, and the pressure inside the reinforced ceramic fiber filter tube is lowered by the air suction device, and the exhaust gas is taken into the interior from the outside to make the exhaust gas contain The dust is isolated from the outer wall of the reinforced ceramic fiber filter tube to achieve a filtering effect. After a period of use, dust accumulates on the outer wall of the reinforced ceramic fiber filter tube to form a dust cake. At this time, a reverse pulse air flow is generated by the system backflushing device, so that the dust cake is from the reinforced ceramic fiber. The surface of the filter tube is detached.
因此，由於該開口段係用以直接或間接連接抽風裝置或其他管線，容易於連接處受力破損，故對於強度的要求較高；此外，該反向脈衝氣流吹入該強化陶纖濾管時，會直接衝擊該封閉段，故該封閉段所承受的力量較強，而亦需要較高的強度。另一方面，該強化陶纖濾管的過濾功能則主要由該延伸段進行，故該延伸段需要較高的孔隙率，而對強度的要求相對較低。 Therefore, since the open section is used for directly or indirectly connecting the air extracting device or other pipelines, it is easy to be damaged at the joint, so the strength requirement is high; in addition, the reverse pulse airflow is blown into the reinforced ceramic fiber filter tube. At this time, the closed section will be directly impacted, so the closed section is subjected to stronger forces and requires higher strength. On the other hand, the filtration function of the reinforced ceramic fiber filter tube is mainly performed by the extension section, so the extension section requires a higher porosity and a relatively lower requirement for strength.
本發明之陶纖濾管強化方法，係使該硬化劑僅吸附於該開口段及該封閉段，該硬化劑不吸附於該延伸段，故不會影響該延伸段之孔隙率，而可以使所製得之強化陶纖濾管仍維持良好的整體過濾效果。同時， 針對容易受到衝擊或夾持而碎裂崩解的開口段及封閉段進行強化，而可以提升所製得之強化陶纖濾管的整體強度。 The ceramic fiber filter tube strengthening method of the present invention is that the hardener is adsorbed only on the open section and the closed section, and the hardener is not adsorbed on the extended section, so the porosity of the extended section is not affected, and The reinforced ceramic fiber filter tube produced still maintains a good overall filtration effect. Simultaneously, The opening section and the closing section which are easily broken or disintegrated by impact or clamping are reinforced, and the overall strength of the obtained reinforced ceramic fiber filter tube can be improved.
為證實本發明之陶纖濾管強化方法確實可以製得該強化陶纖濾管，並提升該強化陶纖濾管之強度，遂進行下述實驗。 In order to confirm that the ceramic fiber filter strengthening method of the present invention can indeed produce the reinforced ceramic fiber filter tube and enhance the strength of the reinforced ceramic fiber filter tube, the following experiment is carried out.
於本實驗中，係使用購自真茂企業股份有限公司之60BD silica及100BD silica矽溶膠作為第A1、A2組之硬化劑，其分別包含以重量百分比計約為42%及45%之二氧化矽；並使用購自AkzoNobel之Bindzil 9950矽溶膠作為第A3組之硬化劑，其包含以重量百分比計約50%之二氧化矽。本實驗所選用之陶纖濾管的總長為300cm，該開口段及封閉段浸泡該硬化劑之長度皆設定為10cm。第A1~A3組各浸泡該硬化劑2次，每次30秒。浸泡該硬化劑後，係於370℃之溫度下烘乾4小時，以製得各組之強化陶纖濾管，另以未經處理之陶纖濾管作為第A0組。分別取第A0組之陶纖濾管及第A1~A3組之強化陶纖濾管，以壓張機測量其抗壓強度，進行數次實驗，並記錄結果如下第1表所示。 In the present experiment, 60BD silica and 100BD silica sol obtained from Zhenmao Enterprise Co., Ltd. were used as the hardeners of Groups A1 and A2, respectively, containing about 42% and 45% by weight of oxidizing agent, respectively.矽; and a Bindzil 9950 sol obtained from AkzoNobel was used as the hardener of Group A3, which contained about 50% by weight of cerium oxide. The total length of the ceramic fiber filter tube selected for this experiment is 300 cm, and the length of the hardening agent soaked in the open section and the closed section is set to 10 cm. Each of the groups A1 to A3 was immersed in the hardener twice for 30 seconds each time. After soaking the hardener, it was dried at 370 ° C for 4 hours to prepare a reinforced ceramic fiber filter tube of each group, and an untreated ceramic fiber filter tube was used as the A0 group. The ceramic fiber filter tube of group A0 and the reinforced ceramic fiber filter tube of group A1~A3 were respectively taken, and the compressive strength was measured by a tensioning machine, and several experiments were performed, and the results are shown in Table 1 below.
請參照第1表，第A1~A3組之強化陶纖濾管的抗壓強度顯著高於第A0組之陶纖濾管，顯示本發明藉由使該硬化劑吸附於該陶纖濾管之開口段及封閉段，續使該硬化劑固化，確實可以提升該陶纖濾管之強度。 Referring to Table 1, the compressive strength of the reinforced ceramic fiber filter tube of Groups A1 to A3 is significantly higher than that of the ceramic fiber filter tube of Group A0, showing that the present invention is adsorbed to the ceramic fiber filter tube by the present invention. The open section and the closed section continue to solidify the hardener, which can indeed enhance the strength of the ceramic fiber filter.
依據上述，本發明之陶纖濾管強化方法藉由使該硬化劑吸附於該陶纖濾管之開口段及封閉段，續使該硬化劑固化，而可以提升所製得之強化陶纖濾管的強度，避免於使用時破損，進而達成「提升該強化陶纖濾管之使用便利性」功效。 According to the above, the ceramic fiber filter strengthening method of the present invention can continue to cure the hardener by adsorbing the hardener on the open section and the closed section of the ceramic fiber filter tube, thereby improving the obtained reinforced ceramic fiber filter. The strength of the tube is prevented from being damaged during use, thereby achieving the effect of "improving the ease of use of the reinforced ceramic fiber filter tube".
再者，本發明之陶纖濾管強化方法，由於該硬化劑並未吸附於該延伸段，故於達成強化效果之同時，不會影響該強化陶纖濾管之過濾能力，達成「提升該強化陶纖濾管之過濾效能」功效。 Furthermore, in the method for strengthening the ceramic fiber filter tube of the present invention, since the hardening agent is not adsorbed to the extension portion, the reinforcing effect is achieved, and the filtering ability of the reinforced ceramic fiber filter tube is not affected, thereby achieving Enhance the filtration efficiency of the ceramic fiber filter tube.
此外，經由本發明之陶纖濾管強化方法所製得之強化陶纖濾管，藉由該延伸段之孔隙率大於該開口段及該封閉段之孔隙率，使該強化陶纖濾管可以具有較高的強度，而不易於使用時破損，達成「延長該強化陶纖濾管之使用壽命」功效。 In addition, the reinforced ceramic fiber filter tube obtained by the ceramic fiber filter strengthening method of the present invention can make the reinforced ceramic fiber filter tube have a porosity greater than a porosity of the open portion and the closed portion.
