The continuous rice husk carbonization furnace sold by Shuliy belongs to a series of natural carbonization furnaces. This continuous rice husk carbonization machine utilizes the principle of dry distillation carbonization to decompose and decompose the fuel rods in the furnace to produce combustible gas, tar and charcoal. The raw materials processed by the equipment may be wood, straw, sorghum, cotton stalk, various straw of weeds, bamboo and other fiber materials. After the materials are placed in the carbonization furnace, three stages are carried out, namely the carbonization stage, the initial stage of carbonization and the comprehensive carbonization stage, which can be processed into finished products after three stages.
Working principle of continuous rice husk carbonization furnace:
The continuous rice husk carbonization furnace produced by our company uses the principle of dry distillation carbonization. The equipment can transform the materials into the furnace for the decomposition of oxygen, and decompose to produce flammable gas, tar and carbon. The three stages of work are as follows:
1. Drying stage: the material enters the furnace, the temperature of the furnace rises, and the moisture contained in the mechanism rod in the furnace mainly relies on the heat generated by external heating and combustion itself, but the chemical structure of the mechanism rod itself does not change;
2. Initial carbonization stage: At this stage, the heat generated by the mechanism rod itself is mainly caused by the temperature rise in the furnace, which is about 180-300 degrees. At this temperature, the mechanism helps to generate decomposition reaction, and its chemical structure will Changes occur, and hemicellulose decomposes to form CO2, CO, and a small amount of acetic acid.
3. Comprehensive carbonization: At this stage, the temperature inside the furnace continues to increase, generally reaching 300-600 degrees. The wood material inside will rapidly decompose and decompose, and at the same time generate a large amount of liquid products such as acetic acid, methanol and wood tar, in addition to methane, Combustible gases such as ethylene; these combustible gases burn and the thermal decomposition of the mechanism rod itself generate a large amount of heat, so that the furnace temperature rises, and the wood material will form a dry carbon at high temperatures.
Continuous rice husk carbonization furnace features:
The continuous rice husk carbonization machine has many advantages. The design adopts the mobile steel plate structure, which is free and convenient when processing. The exhaust pipe at the top of the furnace is connected with the tar separator and the induced draft fan in turn. This design method has large volume and short cycle. With high output and environmental protection, the equipment is advanced and reasonable, and has the advantage of long life. Our company can produce kiln for carbonizing various high, medium and low temperature charcoal.
