Wood Activated Carbon Production Equipment

 BASIC  DESCRIPTION：

  Wood activated carbon is an adsorbent material made from wood as raw material, which has excellent adsorption performance and chemical stability. It is widely used in air and water purification, food processing, pharmaceutical and chemical production, and other fields. The raw materials for the production of wood activated carbon usually come from hardwood, softwood, or waste wood. During the carbonization and activation process, the physical and chemical properties of wood change, forming activated carbon with high porosity and large specific surface area. These porous structures provide a large number of adsorption surfaces, making wood activated carbon have outstanding adsorption performance and selectivity, effectively removing various harmful substances in air and water.

 Production process：

   The wood activated carbon production line mainly includes the following parts: Raw material pretreatment part: Firstly, the raw materials are shaved, crushed, and screened to control the size within 1-3cm. Then, they enter the rotary dryer, using the waste heat of the production line as the heat source to control the moisture content of the raw materials at 8-15%. The exhaust gas from the dryer is treated by dust removal and flue gas washing, meeting the emission standards. Carbonization part: Indirect heating is adopted to carbonize the raw materials. The carbonization temperature is 650-850℃. The rotary drum of the carbonization furnace is made of high-temperature resistant stainless steel and is fully enclosed with a slight negative pressure. The combustible gas generated during carbonization can be used as fuel to provide heat for carbonization without the need for additional fuel. The carbonized charcoal can be directly activated or processed as finished products after cooling.

  1.Activation part: The wood charcoal is activated by indirect heating. The activation temperature is 850-950℃, and the activation time is 60-120 minutes. The rotary drum of the activation furnace is made of high-temperature resistant stainless steel and is fully enclosed with a slight negative pressure. Natural gas/oil is used as fuel, and the temperature, residence time, steam quantity, and oxygen supplement can be precisely controlled to produce wood activated carbon with different specifications. During the production process, the activation furnace will generate a large amount of organic waste gas (hydrogen, carbon monoxide, methane, etc.), which has high heat content. It is burned together with the excess combustible gas from carbonization in the outer furnace of the activation furnace to provide heat for activation.

  2. Cooling part: Water-cooling screw conveyor and rotary drum cooler are used for indirect water cooling. Waste gas treatment part: The waste gas generated during carbonization and activation is treated, including secondary combustion, waste heat steam generation, waste heat recovery, temperature adjustment, pulse dust removal, wet desulfurization, etc. Harmful substances in the exhaust gas can be removed, and waste heat can be maximally utilized.

  3. Finished product processing part: Crushing, grinding, screening, packaging, etc., are carried out on the activated carbon.

 RAW MATERIAL  ：

    Coconut shells, palm shells, bamboo, sawdust, olive shells, fruit shells, hazelnut shells, sawdust, oak, peach pits, etc.

APPLICATION OF FINISHED PRODUCT:

Equipment advantages：

 1. High carbonization yield: Carbonization and activation are carried out in an oxygen-free environment, minimizing carbon loss. The carbonization furnace can control the temperature of each stage of carbonization through segmented temperature control to improve the carbonization yield.

 2.Adjustable product quality: The production process parameters are controllable and adjustable, allowing the production of wood activated carbon with different specifications.

 3. High degree of automation: The entire equipment adopts PLC automation control. Multiple sensors are installed at various process nodes of the production line to monitor and ensure the safety of each link. The process parameters of the equipment can be automatically adjusted through PLC, providing flexibility. The entire production line requires less manual labor, saving labor costs.
