Abstract

The invention relates to oil shale dry distillation device and method. The device comprises an internal combustion retort furnace, and an oil-gas separating device, wherein the internal combustion retort furnace is used for distilling oil shale particles; the oil-gas separating device is used for separating oil shale and gas in smoke generated after oil shale combustion; the internal combustion retort furnace comprises a feeding device, a smoke outlet, a furnace body, a slag discharge device, an air inlet channel and a gas inlet channel; the feeding device is arranged on the top of the internal combustion retort furnace; the smoke outlet is formed in the upper part of the internal combustion retort furnace; the slag discharge device is arranged at the bottom of the internal combustion retort furnace; and the air inlet channel and the gas inlet channel penetrate through the bottom of the internal combustion retort furnace. The oil shale dry distillation device is simple and reasonable in structure, high in oil yield, easy to industrially amplify, convenient to operate, low in production cost, and free of selectivity on grain size of the oil shale; and the oil shale of which the grain size is less than 120mm can be applied to the oil shale dry distillation device.

Description

technical field [0001] The invention relates to an oil shale dry distillation device and a process method for oil shale refining by using the oil shale dry distillation device, belonging to the technical field of oil shale treatment. Background technique [0002] Oil shale (also known as oil shale) is a high-ash sedimentary rock containing combustible organic matter. The main difference between it and coal is that the ash content exceeds 40%, and the main difference from carbonaceous shale is that the oil content is greater than 3.5%. Shale oil can be obtained by low-temperature dry distillation of oil shale. Shale oil is similar to crude oil and can be made into gasoline, diesel or fuel oil. It is called artificial petroleum. In addition to forming pools alone, oil shale often forms associated mineral deposits with coal and is mined together. [0003] The dry distillation of oil shale can be divided into underground dry distillation and aboveground dry distillation. Underg...
