Embodiment Construction

[0006] A production method of activated carbon, which mainly includes carbonization and activation, burning and heating in a calciner, pulverizing the raw materials and then entering the activation furnace. During activation, the raw materials are vaporized by themselves, and the semi-finished products are reused. Under the condition of high temperature and high pressure, it will be completely burned after being isolated from the air, and then the semi-finished product will be crushed, so that the activated carbon can increase the adsorption force, and then activated. Combining with oxygen in the air for activation, and then cooling to make activated carbon, the raw material used in the preparation method of the activated carbon is any one of coal, coconut shells, straw and firewood.

Abstract

The invention discloses a manufacturing method of active carbon. The manufacturing method comprises charing and activation. Raw materials are burned and heated in a calciner, the raw materials are crushed, are fed into an activation furnace and are activated, wherein in activation, the raw materials are self-vaporized, the semi-finished product is recycled, and the activated product is cooled to form a finished product. In calcination, under specific high temperature and high pressure conditions, the raw materials are completely burned without contact with air, and the semi-finished product is crushed so that an active carbon adsorption capacity is improved. Activation is carried after calcination and in activation, the crushed active carbon is fed into the activation furnace, is vaporized at a high temperature and is bonded to oxygen in air so that activation is finished, and the product is cooled to form active carbon. The manufacturing method of active carbon utilizes any one of coal, cocoanut shell, straw and firewood as raw materials.

Description

technical field [0001] The invention relates to a production method, in particular to a production method of activated carbon. Background technique [0002] The main thing about activated carbon is its adsorption, which can be used in many places, but the production process of activated carbon will produce pollutants, and the pollution is quite serious, which cannot be avoided, but activated carbon is widely used, has a high utilization rate, and can be recycled Utilization is a renewable resource, which is in line with the national industrial policy, and pollution is also a big problem that cannot be ignored. Contents of the invention [0003] The present invention aims at the problems existing in the above-mentioned products, and provides a method for making activated carbon to solve the problem that pollutants will be produced during the production of activated carbon in the above-mentioned products, and the pollution is quite serious and unavoidable. Activated carbon i...
