Production process of activated carbon

Abstract

The invention relates to a production process of activated carbon. The production process of activated carbon comprises the following steps: 1, feeding a dried carbonized material to a furnace body through a furnace end feeder of a rotary activating oven, setting the temperature in the furnace body at 800-1000 DEG C, and arranging thermocouple temperature sensing devices and air blowers in front three sections of the furnace body; 2, introducing water steam to the furnace body to be reacted with the carbonized material, controlling the reaction time within 3-10 hours, and recovering tail gases generated by reaction through a tail gas recovery device arranged at the tail of the furnace, and then, mainly introducing the mixed gases in form of CO and H2 to the boiler which generates the water steam for combustion of the boiler; and 3, feeding the activated carbon obtained by reaction from a discharge port at the tail of the furnace to a discharge cooler to be cooled, and smashing, verifying, packaging and putting in storage. According to the production process of activated carbon provided by the invention, the yield is high, the product quality is good, the labor intensity is low, the production efficiency is high, and the process is energy-saving and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of activated carbon production, in particular to an activated carbon production process. Background technique [0002] Activated carbon is a type of microcrystalline carbon material made of carbonaceous materials with a black appearance, developed internal pore structure, large surface area, and strong adsorption capacity. Almost any carbonaceous material can be used to make activated carbon, such as wood, sawdust, nut shells, coal, peat, straw, etc. The key process of manufacturing activated carbon is activation. Due to the different activators used, the activation of activated carbon can be divided into two categories: 1. The chemical activation method using zinc chloride, phosphoric acid or potassium hydroxide as an activator, also known as Chemical activation method; 2. Gas activation method using water vapor or carbon dioxide as an activator, also known as physical activation method. The activated car...

Problems solved by technology

[0005] (1) Due to the inability to control the temperature, steam flow, and oxygen flow in the furnace, the carbonized material cannot be uniformly activated, and the product yield is low, and the product quality is poor and unstable;

[0006] (2) Burning boilers consumes a lot of coal, which leads to high production costs and high energy consumption, which cannot meet the requirements of energy conservation and environmental protection;

[0007] (3) Large exhaust emissions, serious environmental pollution, and large heat loss;

[0008] (4) The process is discontinuous, the labor intensity is high, and the working environment is poor;

[0009] (5) Not suitable for a variety of raw materials
