the carbonization process and equipment of activated carbon activated carbon

the carbonization process and equipment of activated carbon activated carbon

The carbonization process is one of the important processes in the process of producing activated carbon by the gas activation method. This process is to heat the raw material in the air and reduce the non-carbon elements to produce the carbonaceous material suitable for the activation process. It is the pre-activation processalso the main preparation and foundation. In the production process of coal-based activated carbon, the carbonization process usually includes carbonization of materials and carbonization tail gas treatment.

The carbonization process is actually the dry distillation process of the material under low temperature conditions. In this process, the material is gradually heated and heated under a certain low temperature range and the condition of air isolation. The low-molecular substances in the material are first volatilized, and then the coal and coal tar pitch are decomposed and solidified. A series of materials will occur during the entire carbonization process Complex physical changes and chemical changes, of which physical changes are mainly dehydration, degassing and drying processes; chemical changes are mainly two types of reactions, thermal decomposition and thermal polycondensation.

During the thermal decomposition and thermal polycondensation reaction of the material, gas and coal tar are precipitated. The oxygen bonding group of the organic compounds in the material is destroyed, and the oxygen element is precipitated with gases such as Hz0, CO, CO: etc. At the same time, aromatic compounds and cross-linked High-strength carbon molecular structure solid; during the carbonization process, due to the discharge of non-carbon materials such as oxygen and hydrogen during the decomposition at high temperature, the carbon atoms after the loss of oxygen and hydrogen are recombined to form an order with a basic graphite microcrystalline structure The crystals consist of hexagonal carbon atom planes, and their arrangement is irregular, thus forming voids between crystallites. These voids are the initial pores of the carbonized material.

Therefore, the purpose of carbonization is to make the material form a secondary pore structure that is easily activated and to give the mechanical strength required to withstand activation. The requirement for the carbonization of materials is that the appearance of the carbonized material obtained through carbonization must meet certain specifications and shape requirements, the internal structure must have a certain initial pore structure, and at the same time have a high mechanical strength.

(2) In the pyrolysis stage, the raw coal starts to decompose and release pyrolysis water to form gaseous products (such as CQ, C02, H2S, etc.). Different coal types have different pyrolysis temperatures, and coal with low metamorphism starts to heat. The solution temperature is also low. Northeast peat is about 100-1600, lignite is about 200-3000C, bituminous coal is about 300-4000C, and anthracite is about 300-450C. Because the molecular structure and generation conditions of coal are quite different, the above pyrolysis temperature is just a relative reference value between different coal types.

(3) The temperature in the carbonization stage is 300-600 degrees Celsius, mainly polycondensation and decomposition reactions, the raw coal largely precipitates volatile matter, and almost all the tar and gas products precipitated in the carbonization process are produced in this stage. Cohesive bituminous coal gradually softens and melts at this stage to form a colloidal body with three phases of gas, liquid, and solid, and then turns into semi-coke through the processes of flow, polycondensation, and solidification; non-adhesive forms needle-like semi-coke or lump Shaped half-focus.

The final temperature and rate of carbonization are the main operating conditions controlled by the carbonization process. For different coal types, the tar formation process ends at around 550 C. A lot of laboratory research and industrial production experience have shown that 600 is the best final carbonization temperature. If the temperature is too low, the carbonization product cannot form sufficient mechanical strength. If the temperature is too high, the graphite crystallite structure in the carbonization product will be promoted. Ordering, reducing the gap between crystallites, affecting the activation pore formation process. The carbonization heating rate has a great influence on the yield of carbonized products.

The high heating rate can make the material precipitate more tar and coal gas and reduce the yield of carbonized material. When the heating rate is reduced, the material is heated for a long time in the low temperature region, and the pyrolysis reaction has a strong selectivity. The initial pyrolysis breaks the weaker bonds in the material molecule, and parallel and sequential thermal polycondensation reactions occur, forming a The structure with high thermal stability, thereby reducing the yield of volatiles of the thermal decomposition products at high temperature stage, and obtaining a higher yield of solid carbonized products (ie carbonized materials).

The quality of carbonized materials in the carbonization process is mainly evaluated by volatile matter, coke index, water capacity and strength. The volatility of qualified carbonized materials is 7% -18%, the characteristic index of coke yesterday is 1-3, the water capacity is 15% -25%, and the strength of the ball disc is 90%.

Because the measurement of the above indicators requires a certain amount of time, and during the commissioning of the production site, it is often necessary to quickly adjust the process parameters according to the quality of the carbonized material, so the quality of the carbonized material can also be roughly evaluated through the senses. Qualified carbonized materials should have a smooth, crack-free surface, high strength, and consistent color of the material.

1) Carbonaceous material flow: the shaped particles (raw material) are directly lifted into the charging chamber of the rotary kiln by the conveyor, and fall into the drum by gravity, and are brought to the board along the spiral movement in the drum. Move in the direction of the burner. The material first goes through the preheating and drying stage with a temperature of 200 C, and then enters the carbonization stage of 350-550 C. During this process, the carbon particles come into contact with the hot air stream for carbonization to discharge moisture and volatile matter, and finally exported through the export port .

(2) Gas flow: after the tail gas of the furnace is burned in the combustion chamber, a part of the tail gas returns to the furnace head, enters the drum and directly contacts with the countercurrent carbon particles for carbonization; the other part enters the waste heat boiler for heat exchange. The flue gas is discharged from the chimney. Part of the steam generated by the waste heat boiler is sent to the activation process and heat exchange station, and part of it is returned to the furnace head and mixed with the tail gas to enter the carbonization furnace.

vertical furnace for production of active carbon

vertical furnace for production of active carbon

SUBSTANCE: vertical furnace has vertical chamber (retort) housed within heating furnace having square section and fabricated from refractory steel. Steam is fed through pipe extending through the entire height of retort. Charcoal, shavings, or large-sized chips are charged from charging hopper upon opening of lower shutter of charging hopper and shutter disposed in upper part of retort. Active carbon is discharged into car upon opening of rotary hatch. Pyrolysis and activation process products are burnt in furnace to provide for additional heating thereof. Vertical furnace of such construction allows active carbon to be prevented from combustion to protect environment from ecological contamination.

The invention relates to the timber industry, is, in particular, for the production of activated carbon from charcoal or wood wastes and can be used as an additional production of wood processing enterprises.

The invention lies in the fact that the device, which represents a stationary furnace of the vertical type (called a retort), crushed charcoal, wood chips or large chips are heated to a temperature of 780-820in the heat transfer raw materials through the vessel wall with subsequent steaming. So here is exactly this type of furnace is vertical with external heating.

Widely known various kinds of stationary furnace of the vertical type for semi-coking with external heating, in which the coke is obtained by heating the raw material in the combustion of various fuels and heat transfer raw materials through the vessel wall [1, 2].

So, for example, structurally furnace Roll [1] consists of two vertical cylinder, inserted one (cast iron) into another (from a refractory or refractory bricks). Obtaining product on the furnace Roll based on the backfilling of coal in the annular space between the cylinders and the subsequent heating by means of a flue gas formed by burning with coal and Belgacom through heat is emuu surface.

Also known vertical stationary furnace [2, 3] continuous operation with external heating for processing oil shale. Each retort consists of 5 cast iron parts and is located in the chamber of refractory and red brick. Loading from the top, bottom unloading.

Described ovens have the following disadvantages: large size (for example, furnace Roll have a height of up to 14 meters), requiring powerful foundations in manufacturing are very material; a complex mechanism to control the furnace and production technology; use cast iron retort, which can withstand temperatures up to 600With, while to obtain activated carbon required temperature to 900C.

Also known uglevyzhigatelnuyu furnace Policor-2" [4]made of refractory bricks, having a length of 15, width 6 and height 4 IU the RA. In the furnace with the help of a crane inserted metal retort loaded with wood. The furnace has two zones - drying and pyrolysis, in which the retort with wood are set alternately. The retort ready with charcoal is moved to the bookcase, where the cooling and unloading of the retort charcoal. The disadvantage of this design is the high complexity of the process associated with the need to retrieve cock hot retort from the furnace when moving from the drying zone to the pyrolysis zone, and when removed from the furnace retort with the finished product.

The closest analogue is uglevyzhigatelnuyu furnace [5] to obtain charcoal. The essence of this construction is that the furnace two removable vertical retorts through the axial pipe and chimney combined into a single system that, according to the authors, allows to solve the problem of rational use of exhaust gas heat. Charcoal receive queue in each of the retorts, while in another retort drying of wood.

2. Too complex system of ducts, which works as follows: the products of combustion from the furnace enter via the Central nervous system, the Yu tube (located along the entire height of the retort), then fall down the chimney (between the walls of the retort and the casing). Next, the flue gases do the same way in the second retort and go in the chimney. In addition, the retort top to intensify the process steam is fed, which must permeate the mass loading from the top down (?). In order to remove the products of combustion with the high hydraulic resistance will require chimney unrealistic heights.
