INTRODUCTION

   Biomass two-layer continuous coconut shell carbonization plant is a special carbonization equipment which can carbonize coconut shell, walnut shell, apricot shell, hemp pole, sawdust, sawdust, rice husk, bamboo, eucalyptus, mushroom residue, medicine residue, furfural residue, coffee residue, palm shell, peanut shell and sunflower seed shell in the carbonization machine under high temperature conditions.

  The carbonization machine adopts the advanced technology of recovery, purification and circulating combustion of carbon monoxide, methane, ethane and other combustible gases produced in the process of carbonization. It solves the problem of environmental pollution caused by thick smoke which produced by ordinary carbonization furnace in the carbonization project, and solves the heat energy problem required by the equipment, fully realizes self-sufficiency, and improves the continuity and economy of the equipment We should make full use of the agricultural and forestry residues to turn waste into treasure and contribute to the greening environment.

 Biomass continuous drum carbonization machine is a professional equipment for continuous high-temperature heating and carbonization of biomass with a moisture content of less than 15% under anaerobic and oxygen-poor conditions. It is composed of two-layer carbonization machine, preheat wood powder burner (or gasifier, natural gas burner), combustible gas purification device, external heating furnace of carbonization machine, feeding conveyor, cooling and carbon discharging machine and control, etc. The interior of the carbonization machine is divided into four areas: drying area, heating area, carbonization area, and calcination area. The biomass is transported into the inner drum by the conveyor. The waste heat in the furnace is used to dry and preheat the materials to 200-250 ℃.

The biomass is transported by the conveyor into the drum of the carbonization machine. First, the material is dried and preheated to 250°C by using the thermal environment in the furnace. Above, enter the high-temperature carbonization zone of the drum for carbonization at 350-550°C, and finally, calcinate the biomass charcoal at high temperature in the calcination zone to meet the carbon quality required by the product and complete the biomass carbonization. The carbonization machine is equipped with an air outlet and a discharge box. The combustible gas produced by carbonization is discharged from the air outlet, and the wood tar, wood acid liquid, water and ash are separated through the combustible gas purification system to obtain pure combustible gas, and the air is sent into the carbonization machine. The external heating furnace fully burns and heats the carbonization machine to achieve reciprocating cycle heating and carbonization and continuous production. The carbonized products are discharged from the discharge box into the cold carbon machine, and cooled by water to below 45°C, safe carbonization. The excess combustible gas from carbonization can be used for raw material drying or sent out as fuel.

For biomass with a moisture content of 20-40%, the configuration mode of dryer + carbonizer is adopted, and the excess combustible gas produced by the carbonizer is used to dry the biomass. The dryer and the carbonizer work together to fully utilize the combustible gas and reduce Cost of production.

For users who are unwilling to recycle wood acetic acid and wood tar, the carbonization equipment unit of Dingli brand adopts the high and low configuration mode of preheating drying + carbonization. The preheating dryer is arranged on the upper part of the carbonization machine, and the thermal system is comprehensively balanced. Carbonization and drying heating, waste flue gas purification treatment up to standard discharge, higher carbonization efficiency and output ratio, more environmentally friendly.
