How does a carbonization furnace work? The principle of charcoal carbonization furnace

The carbonization furnace uses dry distillation.

The principle of carbonization, the reaction process of heating and decomposition under the condition of air isolation. Distilled wood produces a variety of gases, vapors and solid charcoal. The gas is fed into the bottom of the furnace through the return pipe for self-heating, and wood tar and wood acetic acid can be obtained during the carbonization process.

The flue gas generated during carbonization can be recycled and finally made into charcoal. The equipment is to load wood, bamboo tubes, branches, fruit trees and other raw materials into the furnace, and then heat up the ignition port to ignite the carbonized raw materials inside the furnace, the flue gas generated, after the flue gas purification system filters and removes dust and other temperament, the combustible flue gas is transmitted through the pipeline into the bottom fire channel of the moistening carbonization furnace for combustion, so as to achieve the purpose of secondary heating and heating, so that the raw materials in the furnace reach the temperature and are burned inside the furnace for cracking and carbonization to form charcoal.

The principle of the carbonization furnace is to use the flue gas generated by the internal combustion materials for secondary heating and calcination, and the flue gas is heated back to the bottom and burned in the charcoal making process.

Thermal energy can be recycled to achieve the effect of smoke purification, recycling and fuel saving, and at the same time, the acetic acid, tar and gas produced by materials can also be collected in the carbonization process.

The carbonization furnace takes the self-produced gas furnace as the heat source, uses methane gas through the cyclone, and the air enters the burner, the outlet temperature of the burner can reach 800 1200, and the flow rate can reach 3 5 meters per second, and the high-temperature air flow generated is heated in the periphery of the combustion chamber, it should be noted that when heating, the furnace temperature is 100 150 when the moisture in the furnace is the largest value, and when each kilogram of raw material rod enters the kiln, 4 8% water is brought in, and 1700kg of raw material can bring more than 100 kg of water, which is the enemy of carbonization, because the mechanism of carbon raw material rod is afraid of moistureTherefore, the moisture discharge system is an indispensable key, the moisture discharge time is 1 hour, when the furnace temperature in the carbonization chamber rises to 300, a large amount of combustible gas is produced in the furnace, each kilogram of raw materials can theoretically produce three cubic methane gas, these gases can be used for carbonization heating, drying heat source, the furnace temperature can be adjusted at will, low-temperature carbon is generally more than 400 (8 hours can be completed), high-temperature carbon is more than 600 (10 hours to complete).

The working principle of the mechanism carbonization furnace: the carbonization furnace uses the self-produced gas furnace as the heat source, uses methane gas to pass through the cyclone, and the air distribution enters the burner, the outlet temperature of the burner can reach 800 1200, and its flow rate can reach 3 5 meters per second.

When the initial carbonization equipment is preheated, the biomass gasifier is ignited, and the gasifier is supplied with gas for combustion and heating, waiting for high temperature.

The device for carbonizing the pre-oxidized filament (or phenolic precursor) is mainly a continuous furnace, and the batch furnace is the pre-oxidation furnace, which is carried out by increasing the temperature.

The continuous carbonization furnace is horizontal, but there are two types: (1) the filament tow adopts a furnace structure similar to that of the horizontal pre-oxidation furnace, but due to the short residence time, several slit-type heating plate-shaped long furnaces with different temperatures are mostly used, and the tow is not in contact with the heating surface; (2) For non-woven or felt-like pre-oxidized filament, the above-mentioned carbonization furnace can be used, but if the carbonization temperature is not high, it can also be carried out in the conveyor belt furnace.

Each carbonization furnace is equipped with inert gas inlet and outlet.

Charcoal carbonization furnace has airflow carbonization furnace and dry distillation carbonization furnace, at present, the most widely used is environmentally friendly dry distillation carbonization furnace, Tongli Machinery to talk about the carbonization principle of dry distillation carbonization furnace.

The carbonization furnace takes the self-produced gas furnace as the heat source, uses methane gas through the cyclone, and the air enters the burner, the outlet temperature of the burner can reach 800 1200, and its flow rate can reach 3 5 meters per second, and the high-temperature air flow generated is heated in the periphery of the combustion chamber, it should be noted that when heating, the furnace temperature is the maximum moisture in the furnace when 100 150, and when each kilogram of raw material rod enters the kiln, it brings in 4 8% water, and 1700kg of raw materials can bring more than 100 kilograms of water, which is the enemy of carbonization. Because the machine-made carbon raw material rod is most afraid of moisture, it is crushed into powder when damp, which seriously affects the quality of carbonization, therefore, the moisture discharge system is an indispensable key, the moisture discharge time is 1 hour, when the furnace temperature in the carbonization room rises to 300, a large amount of combustible gas is produced in the furnace, and each kilogram of raw material can theoretically produce three cubic methane gas, these gases can be used for carbonization and heating, and the heat source for drying can be used for heating, the temperature of the furnace can be adjusted at will, and the medium temperature carbon is generally above 400 (8 hours can be completed), and the high-temperature carbon is 600 above (10 hours to complete).

The firing produces a large amount of heat, which increases the furnace temperature and the wood material is dry distilled into charcoal at high temperatures.

I hope to help you, the dry distillation carbonization furnace has vertical and horizontal type.

Household waste. The working principle of low-temperature carbonization furnace equipment is that domestic garbage is at 50-280 degrees Celsius.

Gasification of a part of the plastic at low temperature, the cellulose waste into carbon substance, black carbon is an indispensable energy, its ignition point temperature is about 380 degrees Celsius, the combustion process rarely produces harmful chemical gases.

Low-temperature carbonization furnace.

The structure of the traditional waste low-temperature pyrolysis furnace is relatively fixed, and the treatment effect is not ideal, which is easy to cause secondary pollution. Fire-stamped environmental solid waste.

The pyrolysis furnace is a degradation equipment that integrates pyrolysis and melting gasification to form an involution degradation equipment, and by controlling the temperature and oxygen supply conditions of the equipment, the garbage can be dried, melted and pyrolyzed in the same furnace.

Household waste. Carbon black, a pyrolytic solid-phase product.

It reacts with a small amount of oxygen-rich air from the bottom of the furnace and falls into the bottom oxygen-free zone in the smoldering zone, and slowly forms negative ions in the anaerobic state for a long time.

Ash. Most of the rural household waste has not been sorted and contains a large amount of high-moisture components such as food waste. In different places, due to the difference in economic development and people's living standards, the composition and characteristics of domestic waste are also very different.

Anion ash after carbonization furnace treatment.

In the confined space, the hemicellulose structure of domestic waste carbonization has a branched chain, which is an unstable component in wood, which decomposes at 225 325, and the carbide is more susceptible to thermal decomposition than cellulose, and its pyrolysis mechanism is similar to that of cellulose.

It is mainly used for low-temperature carbonization treatment of pre-oxidized fibers. The asphalt-based oxide fibers produced by the oxidation process enter the low-temperature carbonization furnace. The wire belt is gradually heated to the rated temperature through several heating zones in the furnace.

Low-temperature carbonization furnace is a new type of carbonization technology equipment based on gasification cracking technology for combustible solid waste (garbage) treatment. Its basic working principle is to pass a small amount of magnetized air in the carbonization furnace to thermally decompose the treated combustible solid waste, and then use the generated heat for continuous carbonization of solid waste. Since magnetized air indirectly magnetizes the treated substance, the energy required for carbonization is reduced, and the carbonization efficiency is improved.

The temperature in the furnace is controlled at 250 280 during operation, so that the production of dioxins is basically avoided. The carbonization process does not require any fuel, and it is a new equipment that is environmentally friendly and energy-saving.
