Organic absorbent charcoal and preparing method

Abstract

The invention provides an organic activated carbon and a manufacturing method thereof. The manufacturing method is characterized in that an organic raw material is adopted as natural grass woody rotted plant peat or peat of planus type, and the organic raw material is sent to be rolled and extruded in template type and screened by purifying water so that completed granules, which contain hard and long fibers and various impurities, can be removed; the granules are sun and air dried or heated, mixed and dried; the dried granules are electromagnetically screened so as to remove heavy metal, and are changed into a powdery material, then the powdery material is extruded and molded into grains and carbonized, the grains are carbonized in oxidation protection type by infrared rays, and the carbonized grains are selected by the machine to grade the evenness; the carbonized grains are activated by pure steam, and organic activated carbon is generated; and the finished product is manufactured by special machine models, and grains and powder are graded according to the sizes of the carbon grains. The powder-shaped activated carbon can be refined again in dust free environment to reach the activated carbon of sub-nanometer grade or nanometer grade. Or with reasonable template process, the organic activated carbon of multiple specifications and performances can be manufactured. The organic activated carbon has the advantages of even texture, same weight, thorough carbonization and surface area of high ratio.

Description

Technical field [0001] The invention relates to an organic activated carbon, in particular to an organic activated carbon and a manufacturing method thereof. Background technique [0002] Activated carbon is a unique green environmental protection adsorption material with good adsorption performance and stable chemical properties. It can withstand strong acids and alkalis, and withstand the effects of water immersion, high temperature and high pressure. Compared with other adsorbents, activated carbon has a huge microporous structure and a high specific surface area. Using activated carbon's physical adsorption, chemical adsorption, biological adsorption, catalysis, oxidation and reduction properties, it can remove pollutants in wastewater and air. Activated carbon is widely used in industrial, agricultural, medical, environmental, military, and other fields, so the current market for activated carbon is very large, and by 2006, the US statistical consumption growth rate reached ...

Problems solved by technology

In our country, there are large reserves of herbal organic matter resources. It is very necessary to use the existing rich resources to open up a new way to produce activated carbon; and at present, the ash content of activated carbon needs to be reduced. The surface area, adsorption performance, and strength also need to be improved.
