It is. The prefilter 2 is a non-woven fabric carrying a deodorant, and the fibers constituting the non-woven fabric are not particularly limited. However, the pre-filter 2 is made of a polyester fiber of 5.0 to 20 dtex, and a basis weight of 20 to 80 g / m 2 is preferable. Further, it is preferable that a hydrazine derivative and an inorganic porous material are supported on a non-woven fiber by a binder resin as a deodorant.
ヒドラジン誘導体としては、例えば、ヒドラジン系化合物と長鎖の脂肪族系化合物とを反応させたもの、あるいはヒドラジン系化合物と芳香族系化合物とを反応させたもの等が挙げられる。中でも、ヒドラジン及びセミカルバジドからなる群より選ばれる１種または２種の化合物と、炭素数８〜１６のモノカルボン酸、ジカルボン酸、芳香族モノカルボン酸、および芳香族ジカルボン酸からなる群より選ばれる１種または２種以上の化合物との反応生成物や、ヒドラジン及びセミカルバジドからなる群より選ばれる１種または２種の化合物と炭素数８〜１６のモノグリシジル誘導体及びジグリシジル誘導体からなる群より選ばれる１種または２種以上の化合物との反応生成物が好適である。このようなヒドラジン誘導体を用いることにより優れた悪臭除去性能を確保することができる。前記反応生成物としては、具体的には、セバシン酸ジヒドラジド、ドデカンニ酸ジヒドラジド、イソフタル酸ジヒドラジド等を挙げられるが、特にこれら例示の化合物に限定されるものではない。 Examples of the hydrazine derivative include those obtained by reacting a hydrazine compound and a long-chain aliphatic compound, or those obtained by reacting a hydrazine compound and an aromatic compound. Among them, one or two compounds selected from the group consisting of hydrazine and semicarbazide, and a group consisting of monocarboxylic acid having 8 to 16 carbon atoms, dicarboxylic acid, aromatic monocarboxylic acid, and aromatic dicarboxylic acid are selected. A reaction product with one or more compounds, or one or two compounds selected from the group consisting of hydrazine and semicarbazide, and a group consisting of monoglycidyl derivatives and diglycidyl derivatives having 8 to 16 carbon atoms.

At this time, it is preferable to disperse these deodorants and binder resin as much as possible, and it is more preferable that the binder resin forms an emulsion state with water. In addition, it is preferable to disperse the deodorant in water before mixing and then disperse the binder resin in order to more uniformly disperse the deodorant and the binder resin.
こうして得られる処理剤を不織布に固着させる。この固着する手段としては、特に限定されるものではないが、例えばスプレ−法、浸漬法、コ−ティング法、パディング法等で固着し、加熱乾燥すればよい。 The treatment agent thus obtained is fixed to the nonwoven fabric. The means for fixing is not particularly limited, but may be fixed by, for example, a spray method, a dipping method, a coating method, a padding method, etc., and dried by heating.
前記集塵プリーツフィルター（第二フィルター）は、主に空気中の細かな粉塵を除去するもので、ＵＬＰＡまたはＨＥＰＡといわれる高効率粒子除去プリーツフィルターであるのが好ましい。例えばＨＥＰＡとしては、目付け２０〜１５０ｇ／ｍ２、平均繊度２０〜５０ｄｔｅｘのポリプロピレン繊維製不織布を骨材層にし、その上にポリエステル繊維に銅ゼオライトをバインダー樹脂によって担持した吸着層を重ね、さらに、その上に静電処理した平均繊度０．５〜１５ｄｔｅｘのポリエステル繊維製不織布を重ね合わせ、熱エンボス等の熱処理を施して一体化した後、厚さ０．５〜１．５ｍｍのシートをプリーツ加工機にてひだ折りして得ることができる。ＵＬＰＡはさらにポリエステル繊維の繊度を細くしたもので、さらに細かな粉塵等を捕らえることができる。 The dust collection pleat filter (second filter) mainly removes fine dust in the air, and is preferably a high-efficiency particle removal pleat filter called ULPA or HEPA. For example, as HEPA, a nonwoven fabric made of polypropylene fiber having a basis weight of 20 to 150 g / m 2 and an average fineness of 20 to 50 dtex is used as an aggregate layer, and an adsorption layer in which a copper zeolite is supported on a polyester fiber by a binder resin is further laminated thereon. A non-woven fabric made of polyester fibers with an average fineness of 0.5 to 15 dtex, which is electrostatically treated, is overlaid and integrated by heat treatment such as hot embossing, and then a sheet with a thickness of 0.5 to 1.5 mm is pleated. Can be obtained by folding with a machine. ULPA is made by further reducing the fineness of the polyester fiber and can capture finer dust and the like.
前記集塵プリーツフィルター（第二フィルター）は、静電処理されたポリエステル繊維製不織布の面から、ポリプロピレン繊維製不織布の骨材層に空気が通過するように配置するのが好ましい。ポリエステル繊維製不織布は静電処理されているので、大気中の粉塵を捕らえ、銅ゼオライトの表面が粉塵で覆われるのを防ぐことができる。また、前記銅ゼオライトを担持する吸着層の繊維は、バインダー樹脂で銅ゼオライトを担持できるのであればどのような繊維でも用いることができるが、ポリエステル繊維が好ましい。銅ゼオライトには、大気中の有機溶剤等のＶＯＣ系ガスが強力に吸着される。また、前記ポリプロピレン繊維製不織布の骨材層は、シートがプリーツ加工されるための強度と硬さを付与し、静電環境を整えるものである。こうして得られた集塵プリーツフィルター（第二フィルター）は、タバコの煙のような０．３ミクロン程度の極微粒径の粉塵や塵埃等を捕らえ、除去することができる。 The dust collection pleated filter (second filter) is preferably arranged so that air passes from the surface of the polyester fiber nonwoven fabric subjected to electrostatic treatment to the aggregate layer of the polypropylene fiber nonwoven fabric. Since the polyester fiber nonwoven fabric is electrostatically treated, it can capture dust in the air and prevent the copper zeolite surface from being covered with dust. The fiber of the adsorption layer supporting the copper zeolite may be any fiber as long as it can support the copper zeolite with a binder resin, but a polyester fiber is preferable. VOC-based gases such as organic solvents in the atmosphere are strongly adsorbed on copper zeolite. Moreover, the aggregate layer of the nonwoven fabric made of polypropylene fibers imparts strength and hardness for pleating the sheet, and adjusts the electrostatic environment. The dust collection pleated filter (second filter) obtained in this way can capture and remove dust, dust, etc. having an extremely small particle diameter of about 0.3 microns such as tobacco smoke.
前記光触媒フィルター（第三フィルター）は、酸化チタン、酸化タングステン、酸化亜鉛、酸化銅またはそれらの組み合わせからなる光触媒粒子と、吸着剤として銅ゼオライト、銀ゼオライト、亜鉛ゼオライト、白金ゼオライトの群から選択される１種または複数の金属ゼオライトを、繊維へ担持させた不織布からなることが好ましい。光触媒は、紫外線照射により活性酸素やＯＨラジカルを発現し、各種有機物を分解し、抗菌、防黴等の働きが得られる。また吸着剤として金属ゼオライトを使用することにより、大気中の有機溶剤等のＶＯＣ系ガスが強力に吸着され、光触媒によって分解される。前記光触媒と吸着剤を、不織布を構成する繊維に担持させる方法は、バインダー樹脂により担持させればよいが、光触媒反応によりバインダー樹脂が分解されることから、アクリルシリコン樹脂、フッ素樹脂、シリコン樹脂等の比較的光触媒の影響を受けにくい樹脂から選択してバインダー樹脂とするのがよい。 The photocatalytic filter (third filter) is selected from the group consisting of photocatalytic particles made of titanium oxide, tungsten oxide, zinc oxide, copper oxide or a combination thereof, and copper zeolite, silver zeolite, zinc zeolite, platinum zeolite as an adsorbent. It is preferable that it consists of the nonwoven fabric which carry | supported the 1 type (s) or several metal zeolite to a fiber. The photocatalyst expresses active oxygen and OH radicals by irradiation with ultraviolet rays, decomposes various organic substances, and obtains antibacterial and antifungal functions. Further, by using metal zeolite as an adsorbent, VOC-based gases such as organic solvents in the atmosphere are strongly adsorbed and decomposed by the photocatalyst. The photocatalyst and the adsorbent may be supported on the fiber constituting the nonwoven fabric by a binder resin. However, since the binder resin is decomposed by the photocatalytic reaction, acrylic silicon resin, fluororesin, silicon resin, etc. It is preferable to select a resin that is relatively less susceptible to the photocatalyst as a binder resin.
次に本発明のハニカムあるいはコルゲートフィルター（第四フィルター）を構成する活性炭混抄紙は、通常の湿式抄紙法により製造できる。例えば活性炭と天然パルプを水に添加し、水スラリーを作成する。そのスラリーを攪拌しながら所定の固形分濃度に調整し、その後カチオン系ポリマー又はアニオン系ポリマーを添加し、得られた凝集体水分散液から、抄紙機を使い湿式抄紙法によりシート化し、乾燥処理を行ない活性炭混抄紙を得る。この活性炭混抄紙を、コルゲート加工機を用いハニカム形状やコルゲート形状に加工しフィルターの形状にする。フィルターの形状をハニカム形状やコルゲート形状にすることにより、反応面積が大きくなり、圧力損失を少なくすることができるので、効率的なフィルターとすることができる。 Next, the activated carbon mixed paper making up the honeycomb or corrugated filter (fourth filter) of the present invention can be produced by a normal wet paper making method. For example, activated carbon and natural pulp are added to water to create a water slurry. The slurry is adjusted to a predetermined solid content concentration while stirring, and then a cationic polymer or an anionic polymer is added, and the resulting agglomerate aqueous dispersion is formed into a sheet by a wet paper making method using a paper machine and dried. To obtain an activated carbon mixed paper. This activated carbon mixed paper is processed into a honeycomb or corrugated shape using a corrugating machine to obtain a filter shape. By making the shape of the filter into a honeycomb shape or a corrugated shape, the reaction area is increased and the pressure loss can be reduced, so that an efficient filter can be obtained.
この活性炭混抄紙によるハニカムあるいはコルゲートフィルターは活性炭の強い吸着力によって各種極微量ガスの吸着体の役割をなすものである。本発明に使用する活性炭としては、椰子殻活性炭、石油ピッチ系球状活性炭、活性炭素繊維、木質系活性炭等の活性炭系炭素多孔質体が、吸着比表面積が非常に高いことから好ましく用いられる。中でも、椰子殻活性炭が好ましい。また、この活性炭混抄紙に使用する繊維は天然パルプ、ポリオレフィン及びアクリル繊維などのフィブリル化繊維を用いればよいが、金属フタロシアニン錯体の担持のし易さからも天然パルプが好ましい。 This activated carbon mixed paper honeycomb or corrugated filter serves as an adsorbent for various trace gases due to the strong adsorbing power of activated carbon. As the activated carbon used in the present invention, activated carbon-based carbon porous bodies such as coconut shell activated carbon, petroleum pitch-based spherical activated carbon, activated carbon fiber, and wood-based activated carbon are preferably used because of their very high specific adsorption surface area. Of these, coconut shell activated carbon is preferable. The fibers used in the activated carbon mixed paper may be fibrillated fibers such as natural pulp, polyolefin, and acrylic fiber, but natural pulp is preferable from the viewpoint of easy loading of the metal phthalocyanine complex.
活性炭の抄紙への担持する量は、抄紙の４０〜８０重量％担持させることが好ましい。４０重量％を下回る担持量では十分な吸着力を得ることができず、８０重量％を上回る担持量では活性炭の脱落が発生し好ましくない。より好ましい活性炭の担持量は、６０〜７５重量％である。 The amount of activated carbon supported on the paper is preferably 40 to 80% by weight of the paper. When the loading amount is less than 40% by weight, sufficient adsorption force cannot be obtained, and when the loading amount exceeds 80% by weight, the activated carbon falls off, which is not preferable. A more preferable activated carbon loading is 60 to 75% by weight.
次に前記活性炭混抄紙に担持させる金属フタロシアニン錯体は、特に限定されるものではないが、例えば鉄フタロシアニン錯体、コバルトフタロシアニン錯体、マンガンフタロシアニン錯体が挙げられる。これらの中でもコバルトフタロシアニン錯体を用いるのが好ましく、この場合には、特にメチルメルカプタンやＮＯｘ、ＳＯｘ等の酸化ガスに対する除去性能をさらに向上させることができる利点がある。前記コバルトフタロシアニン錯体としては、特に限定されるものではないが、例えばコバルトフタロシアニンポリスルホン酸ナトリウム、コバルトフタロシアニンオクタカルボン酸、コバルトフタロシアニンテトラカルボン酸等が挙げられる。 Next, the metal phthalocyanine complex supported on the activated carbon mixed paper is not particularly limited, and examples thereof include iron phthalocyanine complex, cobalt phthalocyanine complex, and manganese phthalocyanine complex. Among these, a cobalt phthalocyanine complex is preferably used, and in this case, there is an advantage that the removal performance with respect to oxidizing gas such as methyl mercaptan, NOx, SOx and the like can be further improved. Although it does not specifically limit as said cobalt phthalocyanine complex, For example, cobalt phthalocyanine polysulfonate sodium, cobalt phthalocyanine octacarboxylic acid, cobalt phthalocyanine tetracarboxylic acid etc. are mentioned.
金属フタロシアニン錯体を活性炭混抄紙に担持する前に、活性炭混抄紙をカチオン化処理することが望ましい。これは、金属フタロシアニン錯体の担持量を増大するための処理で、カチオン化処理は活性炭混抄紙の化学構造中にカチオン基を導入付与し得るものであればどのような処理であっても良いが、中でも４級アンモニウム塩によりカチオン化処理が行われるのが好ましい。この場合には、金属フタロシアニン錯体の担持量をより増大させることができる利点がある。前記４級アンモニウム塩としては、例えば３―クロロ―２−ヒドロキシプロピルトリメチルアンモニウムクロライド、グリシジルトリメチルアンモニウムクロライド、３―クロロ―２−ヒドロキシプロピルトリメチルアンモニウムクロライドの縮合ポリマー等が挙げられる。 Prior to supporting the metal phthalocyanine complex on the activated carbon mixed paper, it is desirable to cationize the activated carbon mixed paper. This is a treatment for increasing the amount of metal phthalocyanine complex supported, and the cationization treatment may be any treatment as long as it can introduce and impart a cation group into the chemical structure of the activated carbon mixed paper. Of these, cationization is preferably performed with a quaternary ammonium salt. In this case, there is an advantage that the loading amount of the metal phthalocyanine complex can be further increased. Examples of the quaternary ammonium salt include 3-chloro-2-hydroxypropyltrimethylammonium chloride, glycidyltrimethylammonium chloride, and 3-chloro-2-hydroxypropyltrimethylammonium chloride condensation polymer.
前述のような方法によって、金属フタロシアニン錯体の活性炭混抄紙へ担持させる量は、活性炭混抄紙１ｇ当たり２００〜２００００μｇ担持させるのが好ましい。活性炭混抄紙１ｇ当たり２００μｇを下回る金属フタロシアニン錯体の活性炭混抄紙への担持量では、十分な除去性能を得ることができなく、活性炭混抄紙１ｇ当たり２００００μｇを超える金属フタロシアニン錯体の活性炭混抄紙への担持量では、徒にコストがかさむだけで経済的な担持量とはいえない。より好ましい金属フタロシアニン錯体の活性炭混抄紙への担持量は、活性炭混抄紙１ｇ当たり５００〜５０００μｇである。 The amount of the metal phthalocyanine complex supported on the activated carbon mixed paper by the method as described above is preferably 200 to 20000 μg per 1 g of the activated carbon mixed paper. When the amount of metal phthalocyanine complex that is less than 200 μg per gram of activated carbon mixed paper is supported on the activated carbon mixed paper, sufficient removal performance cannot be obtained, and more than 20000 μg of metal phthalocyanine complex per gram of activated carbon mixed paper is supported on the activated carbon mixed paper. In terms of quantity, it is not an economical carrying amount because it is costly. A more preferable amount of the metal phthalocyanine complex supported on the activated carbon mixed paper is 500 to 5000 μg per 1 g of the activated carbon mixed paper.
前記カチオン化処理された活性炭混抄紙によるハニカムフィルターを水洗し乾燥したあと、金属フタロシアニン錯体で処理し、乾燥したあとさらに弱アルカリ性金属塩水溶液に含浸させ、水洗し乾燥してフィルターを得る。弱アルカリ性金属塩としては、炭酸ナトリウム、炭酸水素ナトリウム、クエン酸ナトリウム、炭酸カリウム、炭酸水素カリウム、クエン酸カリウムの群から選択される１種または複数の弱アルカリ性金属塩が好適である。弱アルカリ性金属塩の活性炭混抄紙への担持量は、活性炭混抄紙１ｇ当たり５〜５０ｍｇ担持させるのが好ましい。弱アルカリ性金属塩は助剤の働きをするものであり、大気中に存在する可能性のあるＮＯｘ、ＳＯｘ等の酸性ガス、硫化水素やメチルメルカプタン等の硫黄系ガスの各種極微量ガスを吸着しやすい環境とする働きをするものである。 The honeycomb filter made of the cationized activated carbon mixed paper is washed with water and dried, then treated with a metal phthalocyanine complex, dried, further impregnated with a weak alkaline metal salt aqueous solution, washed with water and dried to obtain a filter. As the weak alkaline metal salt, one or more weak alkaline metal salts selected from the group of sodium carbonate, sodium hydrogen carbonate, sodium citrate, potassium carbonate, potassium hydrogen carbonate and potassium citrate are suitable. The amount of the weak alkaline metal salt supported on the activated carbon mixed paper is preferably 5 to 50 mg per 1 g of the activated carbon mixed paper. Weak alkaline metal salts act as auxiliaries and adsorb various trace gases such as NOx, SOx, and other sulfur gases such as hydrogen sulfide and methyl mercaptan that may exist in the atmosphere. It works to create an easy environment.
