Abstract
The utility model discloses a multifunctional furnace for a gas heat carrier. The multifunctional furnace comprises a mine storage bin, a destructive distillation segment and an occurring segment, wherein the destructive distillation segment is connected with the mine storage bin and provided with a double-layer gas distribution archway. The occurring segment is connected with the destructive distillation segment and comprises a gas distribution system which is disposed at the bottom and can provide with water vapor. Since the occurring segment connected with the destructive distillation segment is added, when oil shales with low oil content are treated, the occurring segment is started. Through utilization of the gas distribution system of the occurring segment, main gas is leaded to accelerate the occurrence of redox reaction. Coal gas is produced and heat required by the destructive distillation segment is partially complemented, so the automatic balance of the heat energy is achieved. When the oil shales with high oil content are treated, due to the destructive distillation segment with the double-layer gas distribution archway, the occurring segment can be closed for fully circular destructive distillation. With the set of the equipment, whether the oil shales with low oil content or the oil shales with high oil content are treated, the multifunctional furnace can obtain pretty high oil extraction efficiency, good adaptability for raw materials, high utilization rate and product yield coefficient, convertible destructive distillation method, and great treatment capability of single furnace.
