General Introduction Of The Carbonizing Equipment

This machine adopts the design of double layer and multi passage. It is mainly composed of drier, carbonizing machine and other auxiliary equipments. Among these parts, there are other parts like driving, rack, drying, flash steaming, carbonizing, feeding, discharging, cooling, exhaust gas recycling, wet dust catcher, gasification furnace and related pipes. We can equip the machine with chasis if customer needs it (customer-made parts).

Double-layer design make the lower part of the machine contact the hot air as much as possible, this design is helpful to raise the heat utilization efficiency from the beginning. The lower layer equipments utilize residue heat in carbonizing gas to flash steam the materials. This is the second stage to raise the utilization efficiency of heat. The optimized and concentration multi-pipe design of hot exhaust gas (generated from gasifier or hot blast heater) recycling pipe, carbonizing and fission heat collecting pipe, flash steaming steam collecting pipe, combustion emission collecting pipe can raise the heat utilization efficiency in the third time. After three time of optimized usage of heat, the temperature of the emission gas is below 100 centigrade. Under the inspection of related institutes, the heat use ratio of our equipment is over 85%. Our equipment is called perfect flax stem carbonizing equipment by Erie flax factory in Xinjiang province.

The upper part of our machine adopts edge driving and centre screening double drive and stepless speed change structure. The structure can compulsorily change the materials into fine powder in the flash steaming and drying chamber, so the materials can fully contact the hot air, and the controllable rotating speed enable us to control the contacting time of materials and hot air. Then we can get material with the same humidity although their initial humidity is different. After drying, the material will automatically flow into the carbonizing machine in the lower part. The upper part of the machine is for drying material and the lower part is for carbonizing the material.

Usually, we use one equipment to supply hot air ( it can be hot blast stove, the fuel can be coal, branch, biomass pellet, coal gas or other combustible gas; it can also be biomass gasifier, burner and coal spray machine etc.), on one hand, we dry raw materials by using hot exhaust gas and hot air from carbonizing chamber; on the other hand, we use hot air carbonize raw material directly. For undeveloped area, we can use simple single-layer carbonizing machine to process materials with the humidity less than 10% so we can save some investment.
