Structure and principle of carbonization furnace

The structure of the carbonization furnace in the charcoal machine equipment: The insulation material used in the carbonization furnace equipment is perlite. Perlite has insulation properties. The material is cheap, practical, and well sealed. The carbonization furnace is surrounded by refractory bricks and is made of clay and high-aluminum dense refractory materials. It not only resists high temperatures, but also has good thermal insulation properties. It has a simple structure, low cost, high-efficiency internal combustion, and low-temperature retort.

The air flow carbonization furnace (environmentally friendly carbonization furnace) is equipped with advanced filters that can quickly decompose the moisture and tar in the smoke to achieve smoke-free and environmentally friendly effects. This equipment has won the National Science and Technology Award.

The carbonization furnace uses a self-produced gas furnace as the heat source, uses methane gas to pass through a cyclone, and distributes air into the burner. The burner outlet temperature can reach 800°C to 1200°C, and its flow rate can reach 3 to 5 meters per second. The resulting high-temperature airflow When heating around the combustion chamber, attention should be paid to: during heating, the maximum moisture content in the furnace is when the furnace temperature is between 100°C and 150°C. When each kilogram of raw material rods enters the kiln, 4 to 8% moisture is brought in. 1,700kg of raw material can bring Add more than 100 kilograms of water. This water is the enemy of carbonization, because the machine-made carbon raw material rods are most afraid of moisture. They will be crushed into powder when exposed to moisture, which seriously affects the quality of carbonization. Therefore, the moisture drainage system is an indispensable key. The tide time is 1 to 1.5 hours. When the furnace temperature in the carbonization chamber rises to 300°C, a large amount of combustible gas is produced in the furnace. Each kilogram of raw material can theoretically produce three cubic meters of methane gas. These gases can be used to heat up the carbonization and dry it. The heat source is used, and the furnace temperature can be adjusted at will. Low-temperature carbon is generally above 400°C (can be completed in 8 hours), and high-temperature carbon is above 600°C.
