Description

本発明は、二酸化チタンを長期の使用に耐えられるガラス発泡体に担持させた光触媒担持体と、それを取込んで所望の形態にした光触媒浄化フィルターと、光触媒浄化フィルターと紫外線蛍光灯を組合せ、空気中の有害な物質や臭いを分解、処理するための空気脱臭器に関するものである。  The present invention is a combination of a photocatalyst carrying body in which titanium dioxide is carried on a glass foam that can withstand long-term use, a photocatalytic purification filter that incorporates it into a desired form, a photocatalytic purification filter, and an ultraviolet fluorescent lamp, The present invention relates to an air deodorizer for decomposing and treating harmful substances and odors in the air.

一般家庭や会社、自動車等、居住環境の意識向上により空調設備に加え臭気や細菌を除去するための機器、特に臭気は専用の脱臭器あるいは空調機器等に脱臭機能を持たせ空気清浄機等の機器が普及しつつある。従来、この種の脱臭方法は空気中の有害な物質や臭いを、多孔質のゼオライトや活性炭など吸着能力の高い媒体を利用するのが一般的であるが、吸着飽和など能力の限界から車内や冷蔵庫等の狭い空間での利用が多く、媒体も定期的に交換する必要がある。その他、比較的広い空間の脱臭方法として紫外線蛍光等でオゾンガスを発生させ、空気中の有害な物質や臭いを分解する効果に優れた方法もあるが、アンモニアを分解する効果の低いことや、オゾンガスの微臭が欠点とされている。  Equipment for removing odors and bacteria in addition to air conditioning equipment by raising awareness of the living environment, such as general households, companies, cars, etc.Especially, odors have a deodorizing function in dedicated deodorizers or air conditioning equipment, etc. Equipment is spreading. Conventionally, this type of deodorization method generally uses a medium with high adsorption capacity such as porous zeolite and activated carbon to remove harmful substances and odors in the air. It is often used in a small space such as a refrigerator, and the medium needs to be changed regularly. In addition, there is a method that generates ozone gas by ultraviolet fluorescence etc. as a deodorizing method in a relatively large space and has an excellent effect on decomposing harmful substances and odors in the air, but it has a low effect on decomposing ammonia and ozone gas. The slight odor is a disadvantage.

前記、多孔質の媒体やオゾンガスを利用した脱臭方法の欠点を解決することや、脱臭性能の向上を改善する方法として、紫外線によって光触媒である酸化チタンに生じる酸化反応を利用することで優れた脱臭、殺菌などに効果があることから、二酸化チタンを担持させた光触媒浄化フィルターに紫外線を照射することで、空気中の有害な物質や臭いを分解する脱臭機器が下記文献の発明で開示されている。
特開２００１−７９３４９号公報 「脱臭器」 特開２００１−２３８９３９号公報 「空気清浄機」 As a method for solving the above-mentioned drawbacks of the deodorization method using porous media and ozone gas, and improving the deodorization performance, it is possible to achieve excellent deodorization by utilizing the oxidation reaction that occurs in the titanium oxide that is a photocatalyst by ultraviolet rays. Since it is effective for sterilization, a deodorizing device that decomposes harmful substances and odors in the air by irradiating ultraviolet rays onto a photocatalytic purification filter carrying titanium dioxide is disclosed in the invention of the following document. .

特開２００３−２２１２８５「無機系発泡体組成物及び無機系発泡体並びに無機系発泡体の製造方法」 The present invention can obtain the effects described below. According to the first aspect of the present invention, there is provided a titanium dioxide-supported glass foam, characterized in that the surface of the glass foam or the surface and the inner surface of the bubble is covered with a titanium dioxide coating film, The manufacturing method of the glass foam which becomes is disclosed by invention of the following literature, for example.
Japanese Patent Application Laid-Open No. 2003-221285 “Inorganic foam composition, inorganic foam, and method for producing inorganic foam”

この発明は、ガラス廃材やガラス瓶などを粉砕して得られるガラス粉体に、貝殻を粉砕した貝殻粉体を含有したものを溶融後、冷却固化してガラス発泡体を製造するもので、溶融時に貝殻粉体に含有する炭酸カルシュウムが分解して炭酸ガスを発生し、溶融したガラス粉体を発泡させて気泡を形成するとともに、貝殻粉体が焼失することによる微細孔を形成し、表面積の大きなガラス発泡体を安定して得る方法である。本発明の、光触媒担持ガラス発泡体は、一例として、この方法で出来上がったガラス発泡体の表面や微細孔及び気泡面に二酸化チタンの皮膜を覆ったものである。基体のガラス発泡体は一般的なガラスと同様に紫外線に強くて硬い性質を持ち、且つ、発泡により軽量化されたもので、紫外線蛍光灯等など紫外線を照射する光触媒においては、紫外線による物性低下や劣化が殆ど無く、又、光触媒浄化フィルターとして性能低下の原因となる汚れや塵の付着を落とすための洗浄を繰返しても簡単には破損しない。更に前記文献で開示されている発明の「無機系発泡体の製造方法」では広い板状のガラス発泡体を連続的に作るため、本発明の基体となるガラス発泡体は所望の大きさに粉砕等の方法で得ることができる。得られたガラス発泡体は軽量で表面積が大きいことから、性能が良く、軽量で操作性の良い大型の光触媒浄化フィルターにも適している。このように本発明の、ガラス発泡体の表面、若しくは表面と気泡内表面が二酸化チタンのコーテイング膜で覆われた二酸化チタン担持ガラス発泡体は、ガラス瓶などのガラス廃材をリサイクル利用した物を使用でき、コストが安く物性低下や劣化、あるいは破損が少なく長期にわたって使用できる。  This invention is a glass powder obtained by pulverizing glass waste materials or glass bottles, and after melting a shell powder obtained by pulverizing a shell, it is cooled and solidified to produce a glass foam. The calcium carbonate contained in the shell powder decomposes to generate carbon dioxide, foams the molten glass powder to form bubbles, and forms fine pores by burning the shell powder, resulting in a large surface area. This is a method for stably obtaining a glass foam. As an example, the photocatalyst-supported glass foam of the present invention is obtained by covering the surface, fine pores, and cell surfaces of a glass foam produced by this method with a titanium dioxide film. The glass foam of the substrate is resistant to ultraviolet rays and is hard like ordinary glass, and is lightened by foaming. In photocatalysts that irradiate ultraviolet rays such as ultraviolet fluorescent lamps, the physical properties are reduced by ultraviolet rays. There is almost no deterioration and the photocatalyst purification filter is not easily damaged even if it is repeatedly washed to remove dirt and dust adhering to its performance. Furthermore, in the “inorganic foam manufacturing method” of the invention disclosed in the above-mentioned document, a wide plate-like glass foam is continuously produced. Therefore, the glass foam as the substrate of the present invention is pulverized to a desired size. Etc. can be obtained. Since the obtained glass foam is lightweight and has a large surface area, it is suitable for a large-sized photocatalytic purification filter having good performance, light weight and good operability. As described above, the surface of the glass foam or the surface of the glass foam and the inner surface of the bubble covered with the titanium dioxide coating film of the present invention can be used by recycling glass waste materials such as glass bottles. Can be used over a long period of time with low cost, low physical property degradation, deterioration, or damage.

請求項２に記載の発明によれば、請求項１に記載の二酸化チタン担持ガラス発泡体、若しくは二酸化チタン担持ガラス発泡体の集合体からなることを特徴とする光触媒浄化フィルターであって、従来、この種の光触媒浄化フィルターは、前記文献「特許文献１」や「特許文献２」の発明の開示で示されたように、二酸化チタンを担持する基材が紙や樹脂材料で構成されているため紫外線による劣化破損、および塵やホコリを除去する洗浄により、破れや損傷する場合があり、都度フィルターを交換する必要がある。また二酸化チタンを担持する基材を特殊な形状に加工する必要がある等、交換部品として高価となり無駄である。本発明の二酸化チタン担持ガラス発泡体は、前記したようにコストが安く紫外線による物性の低下や劣化、あるいは破損が少なく長期にわたって使用ができるので交換する必要もない。このため、光触媒浄化フィルターを構成する部品も長期に使用するため目的や用途にあわせた複雑な形状や材料で高価となっても無駄とならない。また、光触媒を利用した大型の光触媒浄化フィルターでも二酸化チタン担持体の基体であるガラス発泡体を所望の大きさに粉砕などの方法で得ることができ、強度や大きさ等の設計面で二酸化チタン担持体に制約されることが少ない。このように、本発明の二酸化チタン担持ガラス発泡体、若しくは二酸化チタン担持ガラス発泡体の集合体からなる光触媒浄化フィルターは交換する無駄がなく且つ、形状や構造の設計が二酸化チタン担持体に制約されることが無く、また二酸化チタン担持体が軽量のため大型の光触媒浄化フィルターにも適するものである。  According to the invention described in claim 2, a photocatalyst purification filter comprising the titanium dioxide-supported glass foam according to claim 1 or an aggregate of titanium dioxide-supported glass foam, In this type of photocatalytic purification filter, as shown in the disclosures of the above-mentioned documents “Patent Document 1” and “Patent Document 2”, the substrate supporting titanium dioxide is made of paper or a resin material. Deterioration damage due to ultraviolet rays and cleaning that removes dust and dust may be broken or damaged, and the filter must be replaced each time. In addition, it is necessary to process the base material supporting titanium dioxide into a special shape, which is expensive and wasteful as a replacement part. As described above, the titanium dioxide-supported glass foam of the present invention is inexpensive and can be used over a long period of time, with no deterioration, deterioration, or breakage of physical properties due to ultraviolet rays. For this reason, since the components constituting the photocatalyst purification filter are also used for a long period of time, they are not wasted even if they are expensive due to complicated shapes and materials suitable for the purpose and application. In addition, even a large photocatalyst purification filter using a photocatalyst can obtain a glass foam which is a substrate of a titanium dioxide support to a desired size by a method such as pulverization, and in terms of design such as strength and size, titanium dioxide It is rarely restricted by the carrier. As described above, the photocatalytic purification filter comprising the titanium dioxide-supported glass foam of the present invention or the aggregate of titanium dioxide-supported glass foam is not wasted and the design of the shape and structure is restricted to the titanium dioxide support. In addition, since the titanium dioxide carrier is lightweight, it is suitable for a large photocatalytic purification filter.

特開２００３−２２１２８５「無機系発泡体組成物及び無機系発泡体並びに無機系発泡体の製造方法」 開示されている製造方法で作られたガラス発泡体を、所望の大きさに粉砕などの方法で得た軽量で表面積の大きいガラス発泡体の表面や表面と連通した気泡面に、アナターゼあるいはルチルの結晶形態を持つ二酸化チタンの微粉末を水溶液などの溶液にしたコーテイング材料を、ディップコートやスプレーコートなどの塗布方法で皮膜を形成する。皮膜の形成後、通常は常温で硬化させるが皮膜の密着強度を高めるため塗布前に界面活性剤で下処理を施すことや、塗布後に高温で焼き付けることもある。The preferred best mode for carrying out the present invention will be described below. The best mode for carrying out the invention of claim 1 relating to the titanium dioxide-supported glass foam is the method for producing a glass foam which is a substrate of the titanium dioxide-supported glass foam of the present invention. The invention is disclosed.
Japanese Patent Application Laid-Open No. 2003-221285 “Inorganic foam composition, inorganic foam, and method for producing inorganic foam” A glass foam made by the disclosed production method is obtained by crushing it into a desired size by a method such as pulverization and the like. A coating material is formed by applying a coating material in which a fine powder of titanium dioxide having a crystalline form is made into a solution such as an aqueous solution by dip coating or spray coating. After the film is formed, it is usually cured at room temperature, but in order to increase the adhesion strength of the film, it may be subjected to a pretreatment with a surfactant before coating, or may be baked at a high temperature after coating.

以下、本発明に係わる実施するための形態について、図面を参照して具体的に説明する。本発明の二酸化チタン担持ガラス発泡体に係わる請求項１の発明を実施するため形態は、前記、製造方法で作られた表面に無数の微細孔３と表面に連通した気泡４を形成した所定の大きさのガラス発泡体２に、二酸化チタンのディップコートの親水性を良好にする目的で界面活性剤の溶液に浸した後、容器に入れた結晶子径が約６ｎｍのアナターゼ結晶形の二酸化チタン粉を水と混合した水溶液にディッピィングして皮膜５を形成する。皮膜５はガラス発泡体２の表面６や微細孔３及び気泡４の内面にも形成されるが微細孔３や気泡４の大きさによっては、水溶液が滲入せず皮膜が形成されない場合もある。ディッピィング後に常温で乾燥して硬化させると、本発明の二酸化チタン担持ガラス発泡体１を得ることができる。１００グラムの本発明の二酸化チタン担持ガラス発泡体１を紫外線出力０．８ワットの紫外線蛍光と送風ファンを配置した容積が０．０３立方メートルの密封された箱型の装置に入れ、充填した１０００ｐｐｍのアンモニアと２４時間接触させた。このようにして、二酸化チタン担持ガラス発泡体１の表面６や微細孔３及び気泡４の内面へのアンモニアの物理的吸着平衡に達した二酸化チタン担持ガラス発泡体１を、アンモニア濃度を５００ｐｐｍに設定した装置内で、１２０時間の紫外線照射なしの状態で装置内のアンモニア濃度の測定を行い、その結果、濃度の変化が無いことを確認した後、装置内で紫外線を照射し、送風ファンで空気を循環させた状態での濃度変化の測定をおこなった。図３は本実験によるアンモニア濃度の変化を示した図である。紫外線照射なしのアンモニア濃度は５２０〜５４０ｐｐｍで１２０時間経過しても殆ど変化がみられず、紫外線照射中は当初の濃度５３０ｐｐｍが１２０時間経過後の濃度１１０ｐｐｍに時間の経過と共に減少しており、本発明の二酸化チタン担持ガラス発泡体１が光触媒の媒体として効果を示している。  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to the drawings. In order to carry out the invention of claim 1 relating to the titanium dioxide-carrying glass foam of the present invention, a form in which the innumerable fine holes 3 and the bubbles 4 communicating with the surface are formed on the surface made by the above-described manufacturing method. In order to improve the hydrophilicity of the dip coat of titanium dioxide in the glass foam 2 having a size, the anatase crystal form titanium dioxide having a crystallite diameter of about 6 nm is placed in a container after being immersed in a surfactant solution. The film 5 is formed by dipping the powder into an aqueous solution mixed with water. The coating 5 is also formed on the surface 6 of the glass foam 2, the micropores 3 and the inner surfaces of the bubbles 4. However, depending on the size of the micropores 3 and the bubbles 4, the aqueous solution may not permeate and a coating may not be formed. When dipped and dried and cured at room temperature, the titanium dioxide-supported glass foam 1 of the present invention can be obtained. 100 grams of the titanium dioxide-supported glass foam 1 of the present invention was placed in a sealed box-type device having a volume of 0.03 cubic meters and a UV fan with a UV output of 0.8 watts and a blower fan, and filled with 1000 ppm. Contact with ammonia for 24 hours. In this way, the titanium dioxide-supported glass foam 1 that has reached the physical adsorption equilibrium of ammonia on the surface 6 of the titanium dioxide-supported glass foam 1 and the inner surfaces of the micropores 3 and the bubbles 4 is set to an ammonia concentration of 500 ppm. In the apparatus, the ammonia concentration in the apparatus was measured without ultraviolet irradiation for 120 hours. As a result, it was confirmed that there was no change in the concentration. Concentration change was measured in the state of circulating. FIG. 3 is a diagram showing changes in ammonia concentration in this experiment. The ammonia concentration without ultraviolet irradiation was 520 to 540 ppm, and hardly changed even after 120 hours. During ultraviolet irradiation, the initial concentration of 530 ppm decreased to 110 ppm after 120 hours with the passage of time. The titanium dioxide-supported glass foam 1 of the present invention is effective as a photocatalytic medium.

This is a photocatalytic purification filter 7 taken into the mold container 9. As described above, since the titanium dioxide-supported glass foam 1 of the present invention is lightweight and can be freely selected in size, as another example, the titanium dioxide-supported glass foam of the present invention can be used in a mesh bag made of metal or resin.
