摘要： PURPOSE:To replace the filter for an air purifier mainly removing a tobacco smell, for example, in an eating house, an office or a home. CONSTITUTION:Air containing tobacco smoke is passed through an air purifier wherein a dust collecting filter 7, a first deodorizing filter 6, a second deodorizing filter 5, a suction fan and an air discharge port are successively arranged on the downstream side of an air suction port to be purified and, thereafter, the contaminated filters are replaced. In this case, the dust collecting filter 7 contaminated with tar or the like is detached to arrange the first deodorizing filter used in deodorizing treatment as the dust collecting filter 7 and the first separate deodorizing filter 6 is newly arranged on the downstream side from the first deodorizing filter 6 used in deodorizing treatment. As the first deodorizing filter, a deodorizing filter wherein a hydrazine metal double salt is supported on a carrier formed from a layered clay mineral is used. By this constitution, the removal effect of a tobacco smell by an air purifier is enhanced and the maintenance cost can be reduced.

摘要： PURPOSE:To provide a material for cleaning air for removing CH3CHO, HCHO, (CH3)3N and NH3 or the like and the production method therefor. CONSTITUTION:The material for cleaning air is composed of a complex salt of a metal salt of one kind or two or more kinds of Ni, Al, Zn and Ti and hydrazine. The material for cleaning air is made by carrying the complex salt of the metal salt and hydrazine on a molded body of linear magnesium silicate as a carrying member. The material for cleaning air is produced by dipping the linear magnesium silicate into a mixed solution of the metal salt with hydrazine, drying and carrying the metal salt-hydrazine complex salt or by dipping the linear magnesium silicate into a hydrazine aq. solution after dipping into a metal salt aq. solution and drying to deposite and carry the metal salt- hydrazine complex salt.

摘要： PURPOSE:To obtain an air purifying material capable of efficiently purifying contaminated air containing malodorous gas such as NH3, H2S by bringing metallic iron into contact with a solution of cyanuric acid, trimellitic or trimesic acid, allowing them to react in air for reacting, and allowing to coexist the resulting products with unreacted metallic iron. CONSTITUTION:On the surface of metallic iron, iron, ferrous oxide, ferrous hydroxide, and a complex of iron with an acid are formed to manufacture an air cleaning material. The acid forming the complex is cyanuric acid, trimellitic acid or trimesic acid, or one or two kinds of acids selected from the above group of acids, ascorbic acid, citric acid, gluconic acid, and tannic acid. Metallic iron is brought into contact with a solution of cyanuric acid, trimellitic acid or trimesic acid to allow them to react in air and allowing to coexist reactional products with unreacted metallic iron to manufacture air purifying material. By this air purifying material, contaminated air containing malodorous gas such as NH3, H2S, etc., can be efficiently purified.

摘要： PURPOSE:To fabricate through a simple process a composition which can remove compounds with constantly stable performance and which has power to clean air by adding an oxy-polybasic acid together with water to metals while specifying the amount of the group in a mole ratio against the metals, and causing the acid and the metals to react with each other until the PH of this solution reaches 5.0 to 7.5, and then adding an alkali solution thereto so as to adjust the PH to 6.0 to 14, and using a metal carrier for carrying a composition obtained. CONSTITUTION:One or two kinds of metals selected from among Fe, Mn, Al, Zn, Cr and Cu are made to react with an oxy-polybasic acid in a mole ratio of 1:0.5 to 1 in the presence of water so as to form a reaction solution of the metals and the oxy-polybasic acid of 7.5>PH>5.0. Next, an alkali is added to the reaction solution to fabricate a solution of an air-cleaning composition which is adjusted to 14>PH>6.0. A general alkali such as Ca(OH)2, NaOH, Mg(OH)2 and KOH is used as the above alkali and added directly or as solution to the colloidal reaction solution. The amount of the alkali added is 0.2 to 2% by weight of the metals. The solution of the air- cleaning composition is carried by a carrier which is a molding or sintered body of powder of one or two kinds of metals selected from among Fe, Mn, Al, Zn, Cr, and Cu, to form an air-cleaning material.

摘要： PURPOSE:To minimize pieces of ceramic plates, to bury space in a calcining furnace with uncalcined plate-like porous bodies as much as possible and to reduce the calcining cost by putting the uncalcined plate-like porous body on the ceramic plate and paper or cloth on this and further, the uncalcined plate- like porous body on these and calcining. CONSTITUTION:In the case of calcining the uncalcined plate-like porous body applying iron powder on urethane foam, etc., having 12mm thickness, the uncalcined plate-like porous bodies 1 constitute a laminate unit 5 inserting the paper or the cloth 2, and each constituted unit 5 is put on a ceramic floor plate or shelf (ceramic plate) 3 and calcined. By using this method, three pieces of uncalcined plate-like porous bodies can be piled and put on the ceramic plate having about 10mm thickness, and even if 1mm thickness of five pieces of the papers for parting between these is added, three pieces of uncalcined plate-like porous bodies can be set with about 52mm the total thickness. Only two pieces can be set at the most upper step, but eleven pieces in four steps can be calcined at one time. By this method, the calcining cost can be reduced by about 40%.
