Methyl alcohol purifying device

Abstract

The invention relates to a methyl alcohol purifying device which comprises a cylindrical filtering and purifying box. An opening is formed in the upper end of the filtering and purifying box. A sealing cover capable of being detached is arranged on the opening in the upper end. A gas inlet is formed in the one side of the side portion of a box body of the filtering and purifying box, and an exhaust opening is formed in the other side of the side portion of the box body. An activated carbon filtering layer, a rock cool filtering layer and a fiber filtering layer are sequentially arranged in the filtering and purifying box from the gas inlet to the exhaust opening at intervals. The gas inlet is connected with a hollow sleeve through a gas inlet pipe, and a first magnet and a second magnet are arranged in the hollow sleeve in a vertically opposite mode. The activated carbon layer, the rock cool filtering layer and the fiber filtering layer are in contact connection with the inner wall of the filtering and purifying box. According to the methyl alcohol purifying device, sulfide, other impurities and iron in methyl alcohol can be removed, therefore, the quality of the methyl alcohol can be improved in the production process of the methyl alcohol, and the cleanliness and service life of a silver catalyst are protected better.

Description

technical field [0001] The invention belongs to the technical field of formaldehyde production, and in particular relates to a methanol purification device. Background technique [0002] Formaldehyde is a colorless gas with a strong pungent smell, easily soluble in water, alcohol and ether, formaldehyde is gaseous at room temperature, usually in the form of aqueous solution, formaldehyde is an important organic raw material, mainly used in synthetic. With the development of industry, formaldehyde is used more and more widely as a raw material, such as synthetic fibers, leather industry, medicine, dyes, etc. Formalin has bactericidal and antiseptic capabilities, and can soak biological specimens. Its dilute solution (0.1-0.5%) can be used for soaking and disinfecting seeds in agriculture. [0003] Catalytic oxidation is commonly used in industry to produce formaldehyde from methanol. Formaldehyde is produced by catalytic oxidation of methanol in industry. Therefore, the pur...

Problems solved by technology

[0003] Catalytic oxidation is commonly used in industry to produce formaldehyde from methanol. Formaldehyde is produced by catalytic oxidation of methanol in industry. Therefore, the purity of methanol is directly related to the quality of the produced product. Methanol produced by natural gas and coal chemical industry contains trace impurities , these impurities are difficult to detect, especially crude alcohol contains more impurities, therefore, methanol needs to be pretreated to make the purity of methanol higher, thereby improving the production quality of formaldehyde, but currently there is no A Better Methanol Filtration System
