Destructive distillation method and device for fluidized bed of oil shale

Abstract

The invention discloses a destructive distillation method and a device for a fluidized bed of oil shale to solve the problems that charking loading born by a charking appliance is enabled to be high, charking temperature is hard to control, and the charking appliance is prone to be damaged by over temperature due to the fact that one charking appliance is utilized to conduct charking in the prior art. The destructive distillation method includes the following steps: A. mixing a oil shale raw materials (90) with a high-temperature carrier in a bed type charking appliance (1), enabling the mixed oil shale materials and the high-temperature carrier to enter a bed type destructive distillation reactor (26) to conduct a destructive distillation reaction, stripping carried oil gas in the formed mixed semi-coke through stream, and enabling the mixed semi-choke to enter into a pipe type charking appliance (25); B. conducting one-stage charking on the mixed semi-choke which enters the pipe type charking appliance along the pipe type charking appliance; C. enabling the mixed semi-choke which is conducted the one-stage charking to enter the bed type charking appliance (1) to conduct two-stage charking. The invention discloses the destructive distillation device used for achieving the destructive distillation method for the fluidized bed of the oil shale. The destructive distillation method and the device for the fluidized bed of the oil shale are mainly used for destructive distillation processing of various granularity oil shale raw materials.

Description

technical field [0001] The invention belongs to the technical field of oil shale dry distillation, and relates to a fluidized bed dry distillation method and device for oil shale. Background technique [0002] With the increasing scarcity of oil resources and the advent of the era of high oil prices, the use of oil shale dry distillation technology to produce shale oil in countries around the world has become an important plan to replace and supplement oil resources. Oil shale, also known as kerogen shale, is a sedimentary rock containing organic matter. Organic matter in oil shale is usually composed of two substances: one is asphaltene, and the other is high molecular polymer (called kerogen). Inorganic substances in oil shale mainly include quartz, kaolin, clay, mica, carbonate rock and pyrite. After oil shale is heated and dry-distilled, shale oil, dry distillation gas and shale semi-coke are produced. Shale oil can be directly used as fuel oil, and can also be furthe...

Problems solved by technology

[0004] The purpose of the present invention is to provide a fluidized bed dry distillation method and device for oil shale, so as to solve the problem of using a charcoal burner for charcoal burning in the existing oil shale fluidized bed dry distillation technology. The load of charcoal burning is relatively high, which makes it difficult to control the temperature of charcoal burning and the problem that the charcoal burner is easy to be damaged by overheating
