Problems solved by technology

[0002] For reagents containing volatile and harmful components, such as volatile acidic or alkaline solutions, flammable or explosive low-boiling organic gas, formaldehyde and other volatile gases harmful to human body, usually many need to be placed in a place with ventilation and ventilation. In the special reagent cabinet with special function, it usually needs to be carried out in the fume hood when operating the above-mentioned drugs; the above-mentioned reagent cabinet and fume hood are usually connected with the ventilation system in the laboratory, and the reagents in the reagent cabinet and the fume hood are discharged through the ventilation system. The air polluted by volatile and harmful components is sucked and discharged into the atmosphere for dilution, so as to prevent the harmful components from escaping into the narrow indoor space and causing harm to the workers; but the above-mentioned ventilation system has a complex structure, high manufacturing and maintenance costs, and is discharged into Harmful components in the atmosphere may also have adverse effects on the surrounding environment

Abstract

The invention discloses a copper oxide catalytic filter. The copper oxide catalytic filter comprises an aluminum oxide porous ceramic carrier and copper oxide particles distributed in the aluminum oxide porous ceramic carrier, wherein a heating tungsten wire is further arranged in the aluminum oxide porous ceramic carrier. The preparation method of the copper oxide catalytic filter comprises the following steps: preparing a copper nitrate aqueous solution; impregnating aluminum oxide powder into the copper nitrate aqueous solution; enabling the aluminum oxide powder and the heating tungsten wire to form an aluminum oxide mud block together; drying the formed aluminum oxide mud block under an infrared lamp; placing the dried aluminum oxide mud block in a muffle furnace, wherein the muffle furnace rises to 500 to 800 DEG C from room temperature at a heating rate of 10 DEG C per minute, and then continuously baking for 3 to 5 hours. The copper oxide catalytic filter and the preparation method of the copper oxide catalytic filter disclosed by the invention can be applied to a gas purifying type reagent cabinet and a fume hood to perform oxidation removal of volatile organic matter harmful gases so as to meet requirements of the practical use.
