Embodiment Construction

[0011] As shown in Figure 1, a manufacturing process of shaped activated carbon includes: putting the fruit shell into a carbonization furnace and heating it to about 950°C; then adding water to spray and form high-pressure water vapor; Take it out of the oven at natural temperature; put it into a ball mill and process it into about 200 mesh (0.074 mm); mix it with a non-toxic, odorless, and non-polluting adhesive in a 1:1 ratio and stir evenly; put it in a drying oven at about 145°C Take out after about 45 minutes, both get described extruded gac.

[0012] A kind of manufacturing technology that adopts above-mentioned shaped activated carbon to manufacture activated carbon carbon plate, comprises: described shaped activated carbon is extruded into carbon plate or carbon column by hydraulic press; With extruded carbon plate or carbon column air-dried; Air-dried The carbon plate or carbon column is polished and polished to make activated carbon carbon plate or carbon column.

Abstract

The invention relates to a preparation technique of pressed activated carbon and a method used for manufacturing an activated carbon slab and an activated charcoal column (a square column and a cylinder). The preparation technique of the pressed activated carbon comprises: carbonaceous raw materials are put into a carbonization furnace and heated to 950 DEG C; then water is added to carry out spraying and form high pressure water vapor; shells are cooled to natural temperature after carbonization and taken out of the furnace to be put into a ball mill and processed into about 200 meshes, mixed and evenly stirred with binding agent in a proportion of 1:1, and the mixture is put into a baking furnace with a temperature of 145 DEG C for 45 minutes, and the pressed activated carbon is obtained. The manufacturing technique of the invention employs processing leftover bits and pieces such as shells, bamboo, etc., as major raw materials, which saves cost and achieves environmental effect at the same time.

Description

【Technical field】 [0001] The invention relates to a manufacturing process of shaped activated carbon, and a manufacturing process of using shaped activated carbon to manufacture activated carbon plates and carbon columns. 【Background technique】 [0002] At present, in the manufacturing process of activated carbon, most of them use wood, charcoal, etc. as raw materials for activated carbon, which is costly and not environmentally friendly. 【Content of invention】 [0003] In order to solve the above problems, the present invention proposes a manufacturing process of shaped activated carbon using fruit shells, bamboo and other processing scraps as main raw materials, and a manufacturing process of using shaped activated carbon to manufacture activated carbon carbon plates and carbon columns. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A manufacturing process of shaped activated carbon, comprising: putting carb...
