We have developed a set of oxygen-controlled pyrolysis furnace system for recycling 500000 scrap iron drums per year. The residual organic matter and paint on the surface of scrap iron drums can be removed after treatment by controlled oxygen pyrolysis furnace. The heat-treated waste iron buckets reach the standards for secondary utilization after the subsequent processes of iron barrel shaping, cleaning, painting, etc.
The oxygen-controlled pyrolysis furnace utilizes the principle of oxygen-controlled pyrolysis to stably control the oxygen content in the pyrolysis furnace within the design range, and uses indirect heat exchange to make the furnace temperature suitable for the pyrolysis and gasification of organic matter in the waste iron drum. The resulting pyrolysis gas is thoroughly burned in the secondary combustion chamber, and the flue gas after combustion is then denitrified, deacidified,removed of dust, heavy metals, dioxins and other pollutants to meet emissions standards before it is drawn by induction fans to the chimney stack and released.
