The carbonization furnace is mainly suitable for the synthetic graphite industry, providing a vacuum or atmosphere protection environment to complete the process of pyrolysis of organic matter to form inorganic cracked carbon.
• The high-temperature carbonization furnace is composed of a furnace body part, a power distribution and temperature control part, a gas distribution and air curtain part, and a graphite heating element for resistance heating.
• The equipment is divided into 3 zones to adjust the temperature divisions to form the preheating zone, high temperature zone, and cooling zone required by the process. The ratio of each zone is divided by 1:1:1. The outlet of the high carbon section is equipped with a water-cooled cavity and furnace body. The two ends are equipped with air curtain devices to prevent air from entering the furnace cavity and generate a slight positive pressure airflow to take away the additional products of the carbon paper reaction.
• The carbon paper inlet direction passes through 3 heating zones in sequence. A small amount of gas generated during this process is discharged through both ends of the furnace body. A cone-shaped flue gas collection port with negative pressure ventilation must be set on site to collect and process the flue gas. Prevent impact on the site environment.
