Production process for wooden water-purifying activated carbon

Abstract

The invention belongs to the technical field of production of activated carbon, and provides a production process for wooden water-purifying activated carbon. The production process comprises the following steps: crushing an activated material through a crushing machine so as to obtain a finely-crushed activated material, conveying the finely-crushed activated material to a first screening machineto sieve finely-crushed sand and activated carbon particles with a maximum diameter of less than 2 mm out of the finely-crushed activated material, conveying the activated material sieved for the first time to a second screening machine to sieve activated carbon particles with a maximum diameter of more than 10 mm out of the activated material sieved for the first time, conveying the activated material sieved for the second time to a grinding machine for grinding, conveying the ground activated material to a third screening machine to sieve the activated material with a minimum diameter of less than 2 mm out of the ground activated material, conveying the activated material sieved for the third time to an iron removing machine to remove iron so as to obtain a finished product after completion of iron removal. Thus, the production process for the wooden water-purifying activated carbon provided by the invention solves the problem of incapability of achieving good effects in the grinding stage of the activated carbon in the prior art.

Description

technical field [0001] The invention belongs to the technical field of activated carbon production and relates to a production process of woody activated carbon for water purification. Background technique [0002] Activated carbon is black powder or block, granular, honeycomb amorphous carbon, and there are also regularly arranged crystalline carbon. In addition to carbon, activated carbon also contains two types of admixtures, one is chemically combined elements, mainly oxygen and hydrogen, these elements are left in the carbon due to incomplete carbonization, or in the activation process, foreign Non-carbon elements are chemically combined with the surface of activated carbon; another type of admixture is ash, which is the inorganic part of activated carbon, and ash in activated carbon is easy to cause secondary pollution. Activated carbon is widely used in production and life due to its strong adsorption. [0003] In the prior art, when producing activated carbon, heat...
