Abstract

A moving bed reactor for the medium temperature dry distillation is used in the lignite dry distillation and deep processing based on solid heat-carrying. The moving bed reactor mainly contains a feeder, a shell, baffle plates, a gas pipe, a material outlet and a rapping device. When the moving bed reactor is used, the treated lignite and heat carrier enter the moving bed reactor through the feeder, the feeder and the baffle plates are used to mix the solid material repeatedly, heat carrier and lignite or semicoke perform continuous heat transfer in the moving bed and stay for a certain time,the dry distillation of lignite or semicoke is performed, the generated oil and gas are led out through the gas pipe to an oil-gas separation system, and the solid material is led out through the material outlet to be used as the product or heated again to be used as heat carrrier. The moving bed reactor has the advantages of novel equipment, uniform heat transfer, low heat consumption, safety, economy and the like.

Description

technical field [0001] The present invention relates to a moving bed reactor based on solid heat transfer, in particular to a moving bed reactor for medium-temperature dry distillation, which is used for dry distillation of lignite, oil shale, coal, and oil sand to prepare semi-coke at 700°C-900°C , tar and gas, can be used in industries such as coal chemical industry, energy and power, heating and power supply, and belongs to the technical field of energy utilization equipment. Background technique [0002] Currently used for moving bed retort furnaces for materials such as lignite, oil shale, coal and oil sands, the furnace types include vertical circular furnaces, vertical square furnaces and horizontal cylindrical furnaces. There are two kinds of heating with solid as heat carrier. The solid as the heat carrier can be semi-coke that is burned and heated in the retort furnace, or sand or ceramic balls that are heated in another heating chamber. The hot solid is mixed wit...
