Description
【０００１】[0001]
本考案は、排ガス中の窒素酸化物除去用触媒に係り、特に無機繊維製網状体を 補強材とした薄板状触媒を製造する薄板状触媒装置に関する。 The present invention relates to a catalyst for removing nitrogen oxides in exhaust gas, and more particularly to a thin plate catalyst device for manufacturing a thin plate catalyst using an inorganic fiber mesh as a reinforcing material.
【０００２】[0002]
従来、排ガス中の窒素酸化物（ＮＯｘ）を除去する技術として、アンモニアを 還元剤として注入しＮＯｘを触媒の作用でＮ2に還元するアンモニア接触還元法 が主に採用され実用化されている。処理する排ガス中にはダストが含有されるた め触媒の形状としては、ダストが堆積しにくいハニカム状あるいは板状が主流と なっている。板状触媒については例えば無機繊維製網状体を基材にし、それに触 媒ペーストを塗布してなる板状触媒が考案されている。Conventionally, as a technique for removing nitrogen oxides (NOx) in exhaust gas, an ammonia catalytic reduction method in which ammonia is injected as a reducing agent and NOx is reduced to N 2 by the action of a catalyst has been mainly adopted and put into practical use. Since the exhaust gas to be treated contains dust, the main catalyst shape is a honeycomb or plate shape in which dust is hard to accumulate. As the plate-shaped catalyst, for example, a plate-shaped catalyst has been devised in which a net-like body made of an inorganic fiber is used as a base material and a catalyst paste is applied thereto.
【０００３】 上側無機繊維製網状体４と下側無機繊維製網状体６の間に触媒ペースト５を挾 み、上側塗布圧着ロール１、下側塗布圧着ロール２に上側無機繊維製網状体４と 下側無機繊維製網状体６の繊維や触媒ペースト５が付着しないように例えば紙、 プラスチックフィルムの上側付着防止シート１３及び下側付着防止シート３を介 して回転・圧着し、板状触媒１４に成形するものである。成形した板状触媒を製 品として使用する場合、所定長さに切断し、その後、排ガス流路を構成するため 必要形状に板状触媒を成形し、触媒の活性化のため数百度にて焼成処理し、その 後図７、図８に示すような形に数十枚積み重ねてユニット化し、このユニットを 十数個合わせてブロック化し、実機の反応器に充填する。A catalyst paste 5 is sandwiched between the upper inorganic fiber net-like body 4 and the lower inorganic fiber net-like body 6, and the upper inorganic fiber net-like body 4 is attached to the upper coating pressure bonding roll 1 and the lower coating pressure bonding roll 2. In order to prevent the fibers of the lower inorganic fiber net-like body 6 and the catalyst paste 5 from adhering to each other, for example, the sheet-shaped catalyst 14 is rotated and pressure-bonded through the upper adhesion preventing sheet 13 and the lower adhesion preventing sheet 3 of paper or plastic film. It is to be molded into. When using the molded plate catalyst as a product, cut it to a specified length, then mold the plate catalyst into the required shape to configure the exhaust gas flow path, and fire at several hundred degrees to activate the catalyst. After processing, dozens of them are stacked in a shape as shown in FIGS. 7 and 8 to form a unit, and a dozen or more of these units are combined into a block and filled in a reactor of an actual machine.
【０００４】 上記の触媒ペーストを無機繊維製網状体にローラ塗布した平板状の触媒（以下 、触媒エレメントと称す）の一方の触媒エレメント表面に排ガス流路を構成する ためのスペーサ部分を凸状に同時に付加させながらローラ塗布を行いその後乾燥 、焼成する技術は、特開昭４７−４３０号公報、特開昭４８−６７３０５号公報 、特開昭４８−６８６０８号公報及び特開昭６１−２２７８４５号公報により公 知である。A spacer portion for forming an exhaust gas passage is formed in a convex shape on one catalyst element surface of a flat plate-shaped catalyst (hereinafter referred to as a catalyst element) in which the above-mentioned catalyst paste is roller-coated on an inorganic fiber net-like body. Techniques of roller coating while simultaneously adding and then drying and firing are disclosed in JP-A-47-430, JP-A-48-67305, JP-A-48-68608 and JP-A-61-227845. It is public knowledge in the bulletin.

上述のように図６に示す従来の薄板状触媒製造装置は上側塗布圧着ロール１、 下側塗布圧着ロール２に上側無機繊維製網状体４と下側無機繊維製網状体６の繊 維や触媒ペースト５が付着しないように例えば紙、プラスチックフィルムの上側 付着防止シート１３及び下側付着防止シート３を用いているが、そのため触媒表 面にしわが出来ないように上側無機繊維製網状体４、下側無機繊維製網状体６と 同期回転させ、かつ張力を付与する供給、巻取り装置を必要とし、上側塗布圧着 ロール１若しくは下側塗布圧着ロール２のいずれかに設けた溝に付着防止シート が介在するので触媒表面に形成する凸部、即ちスペーサ部分の精度が低下する。 As described above, the conventional thin plate catalyst production apparatus shown in FIG. 6 has the upper coating pressure bonding roll 1 and the lower coating pressure bonding roll 2 in which fibers and catalysts of the upper inorganic fiber netting 4 and the lower inorganic fiber netting 6 are formed. The upper side anti-adhesion sheet 13 and the lower side anti-adhesion sheet 3 of, for example, paper or plastic film are used so that the paste 5 does not adhere. A supply and take-up device that rotates in synchronization with the side inorganic fiber net-like body 6 and applies tension is required, and the adhesion preventing sheet is provided in the groove provided in either the upper coating pressure bonding roll 1 or the lower coating pressure bonding roll 2. Because of the interposition, the accuracy of the convex portion formed on the catalyst surface, that is, the spacer portion decreases.
【０００６】 また、付着防止シートは消耗品であり、付着防止シートに触媒ペースト５が付 着することを避けられないので板状触媒１４の歩留まりが低下し、付着防止シー トを使用しない構造が要望されている。Further, since the anti-adhesion sheet is a consumable item, it is unavoidable that the catalyst paste 5 is attached to the anti-adhesion sheet, so that the yield of the plate-like catalyst 14 is reduced, and the anti-adhesion sheet is not used. Is requested.
【０００７】 本考案の目的は、単純な構成の薄板状触媒製造装置を提供することにある。An object of the present invention is to provide a thin plate catalyst manufacturing apparatus having a simple structure.
【０００８】[0008]
上記目的は、上側無機繊維網状体と、下側無機繊維網状体及び下側付着防止シ ートで侠持した触媒ペーストを圧着・塗布して板状触媒に成形する上側塗布用ロ ールと下側塗布用ロールからなる一対の塗布用ロールのうち、該上側塗布用ロー ルはテフロン被覆した表面に円周方向に少なくとも２個以上の凹状に形成したロ ールであることにより達成される。 The purpose of the above is to provide an upper inorganic fiber reticulate body and an upper coating roll that press-bonds and coats the lower inorganic fiber reticulate body and the catalyst paste supported by the lower adhesion prevention sheet to form a plate-shaped catalyst. Of the pair of lower coating rolls, the upper coating roll is achieved by being a roll having at least two concave portions circumferentially formed on the surface coated with Teflon. .
【０００９】[0009]
上記構成によれば、上側塗布用ロールにテフロン被覆を施すことにより、触媒 ペーストが上側塗布用ロールに付着しなくなるから上側付着防止シートは不要と なり、装置構造の単純化が可能となる。 According to the above configuration, by applying the Teflon coating to the upper coating roll, the catalyst paste does not adhere to the upper coating roll, so that the upper adhesion preventing sheet is not required and the structure of the apparatus can be simplified.
【００１０】 また、板状触媒の歩留まりが向上し、製造コストの軽減も可能となる。Further, the yield of the plate-shaped catalyst is improved, and the manufacturing cost can be reduced.
【００１１】[0011]
以下、本考案の実施例を詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail.
【００１２】 まず、触媒エレメントの板厚を１．０ｍｍ以下、好ましくは０．８ｍｍ以下にす るための無機繊維製網状体の仕様としては以下の通りである。すなわち、該無機 繊維製網状体２枚を用い、その間に触媒成分からなる触媒ペーストをはさみこん で、上下のロールで圧延塗布、成形する場合には、当然のことながら、無機繊維 網状体１枚の板厚は触媒エレメントの板厚の１／２以下となる。この様な薄板用 の無機繊維網状体としては、ヤーン当りの繊維数を減らして板厚を下げることに なる（例えば１４００本／ヤーンが８００本／ヤーン、１０００本／ヤーンに減 少）ので、ヤーン１本当りの強度は低下する。そこで、目抜手織りの織り方にお いては１インチ当りのヤーンの本数を増すことも必要となる。一方、無機繊維網 状体１枚を用いる場合には、触媒エレメントの板厚と同等またはそれ以下であれ ばよい。First, the specifications of the inorganic fiber reticulate body for making the plate thickness of the catalyst element 1.0 mm or less, preferably 0.8 mm or less are as follows. That is, when two sheets of the inorganic fiber reticulate body are used and the catalyst paste consisting of the catalyst component is sandwiched between them and roll-coated and molded by the upper and lower rolls, one sheet of the inorganic fiber reticulate body is naturally used. Is less than 1/2 of the thickness of the catalytic element. As such an inorganic fiber network for thin plates, the number of fibers per yarn is reduced to reduce the plate thickness (for example, 1400 fibers / yarn is 800 fibers / yarn, 1000 fibers / yarn is reduced). The strength per yarn decreases. Therefore, it is also necessary to increase the number of yarns per inch in the stitched handwoven weave. On the other hand, when a single inorganic fiber network is used, it may have a thickness equal to or less than the plate thickness of the catalyst element.
【００１３】 一方、触媒エレメントに形成する凸部の形状及びその間隔は、触媒エレメント の板厚、触媒エレメント間の間隔を決める凸部高さ、凸部の間隔及び凸部の幅に より左右される圧力損失及び触媒表面積から決定され、考案者らの検討の結果、 触媒エレメントの板厚が１ｍｍ以下で触媒エレメントを積層した時の開口率が７ ０〜８５％の時に、従来のものに比べ圧力損失が同等で、同一脱硝率を得るため の触媒容積が従来よりも小さくなることが明らかとなった。すなわち、開口率が ７０％以下になると圧力損失が従来のものと比べ１．３倍以上と著しく大きくな る。一方、開口率が８５％以上になると、圧力損失は低下するものの触媒容積が 従来のものとほぼ同等になるためである。触媒エレメントの板厚を薄くし、最適 な凸部形状、その間隔を設定することにより、従来のものに比べ、低圧力損失で 触媒量の少ない反応器が可能になる。On the other hand, the shape of the convex portions formed on the catalyst element and the distance between them depend on the plate thickness of the catalytic element, the height of the convex portions that determine the distance between the catalytic elements, the distance between the convex portions, and the width of the convex portions. It is determined from the pressure loss and the catalyst surface area, and as a result of the study conducted by the inventors, when the plate thickness of the catalyst element is 1 mm or less and the opening ratio when the catalyst elements are laminated is 70 to 85%, compared with the conventional one. It was revealed that the pressure loss is equivalent and the catalyst volume for obtaining the same denitration rate is smaller than before. That is, when the aperture ratio is 70% or less, the pressure loss is 1.3 times or more, which is significantly larger than that of the conventional one. On the other hand, when the opening ratio is 85% or more, the pressure loss decreases, but the catalyst volume becomes almost the same as the conventional one. By making the thickness of the catalyst element thin and setting the optimal convex shape and its interval, a reactor with lower pressure loss and smaller amount of catalyst becomes possible compared to the conventional one.
【００１４】 しかし、前述したように、こうした薄板の触媒エレメントでは、従来構造の波 部は加熱成形後も、波部の形を保持することが困難である。そのため、触媒エレ メントに凸部を設置し、ガスの流路を確保するとともに、触媒エレメントを積層 した時、下段の触媒エレメントの凸部と上段の凸部が同一位置になる様配置する ことにより、圧縮荷重をこの凸部で受持つこととする。実装置においては、この 圧縮荷重は主に触媒エレメントの自重によるものであり、触媒エレメント最下段 の荷重としては１凸部当り高々１ｋｇ／ｃｍ2である。これに対し、本考案の触 媒エレメントでの凸部の圧縮強度は５０ｋｇ／ｃｍ2以上で十分実装置での荷重 に耐えうるものである。但し、上下触媒エレメントでの凸部の位置が異なる場合 には、凸部を含む平面が荷重を受けもつことになるが、触媒エレメントが薄板に なると平面部の曲げ強度が低下し、圧縮荷重方向に変形して所定の流路形状を保 持できなくなる。However, as described above, in such a thin plate catalyst element, it is difficult for the corrugated portion having the conventional structure to maintain the shape of the corrugated portion even after the thermoforming. Therefore, by installing a convex part on the catalyst element to secure a gas flow path, and by arranging the convex part of the lower catalyst element and the convex part of the upper stage to be in the same position when stacking the catalyst elements , The compressive load is to be taken up by this convex portion. In an actual device, this compression load is mainly due to the own weight of the catalyst element, and the load at the bottom of the catalyst element is 1 kg / cm 2 at most per convex portion. On the other hand, the compressive strength of the convex portion of the catalytic element of the present invention is 50 kg / cm 2 or more, which is sufficient to withstand the load in the actual device. However, if the positions of the convex portions on the upper and lower catalytic elements are different, the plane including the convex portions will bear the load.However, if the catalytic element becomes a thin plate, the bending strength of the planar portion will decrease and the compressive load direction It becomes deformed into a shape and cannot maintain a predetermined flow path shape.
【００１５】 また、この凸部の断面形状としては、前記した長方形の他に、台形、三角形、 半円、ダ円等特に限定するものではない。特に、平面部と凸部、突起部との交点 をＲ取り形状にしたものは、触媒との反応が促進され有効である。Further, the cross-sectional shape of the convex portion is not particularly limited to the trapezoid, the triangle, the semicircle, the da circle other than the above-mentioned rectangle. In particular, the one having a rounded shape at the intersection of the flat portion, the convex portion, and the protruding portion is effective because the reaction with the catalyst is promoted.
【００１６】 第１実施例 本実施例の無機繊維としては、Ｅガラス、Ｔガラスなどのいわゆる無アルカリ ガラス製長繊維縒り糸からなる織布が好ましく使用される。繊維径については特 に制限するものでなく、数〜数十ミクロンであればよいが、これらを縒り合わせ て１本のヤーンにする場合には、ヤーンの太さ及び目数を調整する必要がある。 すなわち、本実施例の場合には、繊維径６ミクロンを８００本縒ったヤーンを１ インチ当り１０本で目抜き織りしている。この場合、タテ糸と、ヨコ糸とのずれ を防止するため、ヨコ糸と交差する処でタテ糸を２分割してヨコ糸をはさむ方法 で織ったからみ織りである。First Example As the inorganic fiber in this example, a woven fabric made of so-called non-alkali glass long fiber twisted yarn such as E glass and T glass is preferably used. The fiber diameter is not particularly limited and may be several to several tens of microns, but when these are twisted together to form one yarn, it is necessary to adjust the thickness and the number of yarns. is there. That is, in the case of this embodiment, 800 yarns each having a fiber diameter of 6 microns are knitted and weaved at 10 yarns per inch. In this case, in order to prevent the warp yarns and the weft yarns from slipping off from each other, the warp yarns are woven in such a manner that the warp yarns are divided into two at the intersection with the weft yarns and the weft yarns are sandwiched.
【００１７】 この無機繊維網状体は、ゾル状のコロイダルシリカ、１ミクロン以下の粒径の ものが９０％程度の酸化チタン粉末およびポリビニールアルコールとを含有する スラリを浸漬法またはスプレー法によって担持され、しかる後に１００〜２００ ℃で乾燥して剛性のある板厚０．３５ｍｍの触媒担体用基材を作る。この基材を そのまま、または３〜１０％塩酸、硝酸、硫酸などの酸溶液中に浸漬し、５０〜 １００℃に加温しながら数時間処理して無機繊維表面のＣａＯ、Ａｌ2Ｏ3の一部 を溶出させ、水洗、乾燥したものを用いてもよい。This inorganic fiber network is supported by a dipping method or a spray method with a slurry containing colloidal silica in the form of sol, a titanium oxide powder having a particle size of 1 micron or less and about 90% and polyvinyl alcohol. Then, it is dried at 100 to 200 ° C. to prepare a rigid substrate for catalyst carrier having a plate thickness of 0.35 mm. This substrate as it is, or immersed in an acid solution of 3 to 10% hydrochloric acid, nitric acid, sulfuric acid, etc., is treated for several hours while being heated to 50 to 100 ° C. to remove CaO and Al 2 O 3 on the inorganic fiber surface. A part of the product may be eluted, washed with water and dried.
【００１８】 このようにして得られた基材を２枚用い、その間に、酸化チタンを主成分とす る触媒成分粉末と、セラミック繊維の混合したものに水を混ぜ合わせて粘土状に した触媒成分をローラを用いて塗布する。この時、本実施例になる塗布法は以下 の通りである。Using two sheets of the base material thus obtained, a mixture of a catalyst component powder containing titanium oxide as a main component and ceramic fiber and water in the meantime to form a clay-like catalyst The ingredients are applied using a roller. At this time, the coating method according to this embodiment is as follows.
