Brief description of the production process
The machine is equipped with: crushing system, drying system, liquefied gas combustion system, flue gas purifier, fan, self-distributing gas burner, dry distillation carbonization furnace, secondary combustion chamber, grinding system, environmental protection carbon rod production and other equipment ( See attached image for details).
This system is energy-saving, environmentally friendly, dust-free, smoke-free and tasteless. The direct-fired type does not produce wood tar and wood vinegar. It adopts the double-drum dry distillation and carbonization method to make full use of the combustible gases such as carbon monoxide, methane, and hydrogen generated in the carbonization process. The gas purification system separates dust (the dust will enter the cold carbon machine with the cold carbon equipment) and pure combustible gas, and then fully burns through the self-distributing air burner to heat the high temperature carbonization equipment (the temperature is generally controlled at about 700-800 ℃ ). There are double sleeve pipes inside the carbonization machine, the inner barrel is a preheating and drying pipe, and the outer barrel is a high temperature carbonization pipe. The inner cylinder pipe uses the waste heat in the furnace to dry the material, and the outer cylinder is provided with a combustible gas recovery pipe. The combustion of the burner heats the pipeline, and the mixed gas collected from the carbonization equipment enters the filter system from the lower part, and the filtered pure gas is recycled to the combustion chamber heating equipment to achieve the effect of reciprocating cycle heating and carbonization. The primary carbonization ignition gas source is supplied by the liquefied gas combustion system.
