What equipment is needed for the whole production line of activated carbon?

Activated carbon is currently one of the indispensable purification and adsorption products in the industrial and civil fields, and its products can effectively adsorb impurities and toxic substances in the air and liquid. The raw materials for the production of activated carbon are common all kinds of fruit shells (such as: coconut shells, apricot shells, walnut shells, etc.), coal such as anthracite and refined coal, and wood types are all kinds of logs.

The following is an introduction to the basic equipment needed in the production of activated carbon. First, the carbonization furnace is a cylinder installed vertically on the ground, and has a feed port and a discharge port. 2. Heating furnace, which is connected to the carbonization furnace and heated from the outside.

3. Liquefaction furnace, the gas in the liquefaction furnace comes from the gas discharged from the carbonization equipment, and is liquefied in this time. Fourth, the appearance of the activation furnace is similar to the carbonization furnace, and the function of the carbonization furnace is different in that it can make the activated carbon heat to a higher temperature. 5. Mixer, through the stirring equipment, the activated carbon is rotated and stirred at the specified speed, so that the activated carbon in the carbonization and activation process can be heated evenly.

The activated carbon Shaanxi Yanhe Heavy Industry production line adopts the most environmentally friendly physical preparation process, which carbonizes raw materials such as coconut shells and fruit shells first, and then enters the activation furnace after crushing and screening to a certain particle size. After activation, the sand and gravel, iron nails and other impurities are separated by a vibrating screen and a desander, and then mechanically crushed and screened into a finished activated carbon with the required particle size. Activated carbon production equipment includes:

Aggregates, conveyors, dryers, calcining kilns, winnowing machines, crushers, screening machines, washing machines, mills, packaging machines and other equipment.

Activated carbon can be divided into physical water vapor method and chemical production according to the production method, here we focus on the production of physical water vapor method, the general production is divided into two processes, the first step, carbonization, the raw material is dried at a temperature of 170 to 600, and the same amount of 80% R organic tissue carbonization. The second step, activation, sends the carbonized material that has been carbonized in the first step into the reaction furnace, reacts with the activator and water vapor, completes its activation process, and makes a finished product. In the process of endothermic reaction, the combined gas of CO and H2 is mainly generated, which is used to heat the carbonized material to an appropriate temperature (800 to 1000 degrees), remove all its decomposable products, and produce a rich pore structure and a huge specific surface area, so that the activated carbon has a strong adsorption force.

The activated carbon produced by different raw materials has different pore sizes, among which the pore size of activated carbon with coconut shell as raw material is the smallest, the pore size of wood activated carbon is generally larger, and the pore size of coal activated carbon is between the two. Activated carbon pore size is generally divided into three categories: macropores:

1000-1000000A Transition Pore: 20-1000A Micropores: 20A According to the above characteristics, it can be seen that for different adsorption objects, the corresponding activated carbon needs to be selected to achieve the best cost performance.

The adsorption capacity of activated carbon is related to the level of water temperature and the quality of water quality. The higher the water temperature, the stronger the adsorption capacity of activated carbon; If the water temperature is as high as 30 or more, the adsorption capacity reaches the limit and may gradually decrease. When the water quality is acidic, the adsorption capacity of activated carbon for anionic substances is relatively weakened. When the water quality is alkaline, the adsorption capacity of activated carbon for cationic substances is weakened.

Therefore, the pH of water quality is unstable, which will also affect the adsorption capacity of activated carbon.

The adsorption principle of activated carbon is: to form a balanced surface concentration on the surface of its particles, and then adsorb organic impurities into the activated carbon particles, and the adsorption in the initial stage of use is very high. However, over time, the adsorption capacity of activated carbon will be weakened to varying degrees, and the adsorption will also decline.

If the water in the aquarium is turbid and the water contains high levels of organic matter, activated carbon will quickly lose its filtration function. Therefore, activated carbon should be cleaned or replaced regularly. The size of the activated carbon particles also has an impact on the adsorption capacity.

In general, the smaller the activated carbon particles, the larger the filtration area. Therefore, powdered activated carbon has the largest total area and the best adsorption, but powdered activated carbon is easy to flow into the aquarium with water, which is difficult to control and is rarely used. The granular activated carbon is not easy to flow due to the particle forming, and the impurities such as organic matter in the water are not easy to block in the activated carbon filter layer, and its adsorption capacity is strong.

Note: Activated carbon has a shortcoming, especially in the newly renovated store or home storage cabinet in the concentration of phenolic substances is very large, these substances will be adsorbed by activated carbon, activated carbon adsorption to a certain extent will be saturated, need to return to the factory to activate, people will be troublesome will be replaced by Huankang nano live ore, their properties are the same, there is a good adsorption effect.

It is produced by the reaction of charcoal, charcoal and other carbon materials with coal gas at high temperatures!

Activated carbon is a specially treated form of carbon with a porous structure, low bulk density, and large specific surface area, which can be used for filtration adsorption or the preparation of catalyst carriers.

Due to its high degree of microporosity, the surface area of one gram of activated carbon can exceed 3,000 [1][2]. Almost all applications of activated carbon are based on this characteristic of activated carbon. [3] Its adsorption properties can be improved by further chemical treatment.

Activated charcoal is usually prepared from charcoal. [1][2] prepared from coal or corn is known as activated coal. Active coke** than coke.
