Embodiment Construction

[0016] As shown in the figure, the tailings oil shale has a particle size of 0mm to 20mm, and after crushing and screening, it becomes small-grain oil shale in the particle size range of 0mm to 12mm. It is transported to the inlet of the drying winnowing system, enters the drying winnowing system and passes into the hot flue gas. The drying air separation system uses multi-layer mechanical vibration to process incoming shale materials. The whole system is fully enclosed. While shale is being screened, hot flue gas is introduced from the bottom to contact the shale in reverse to dry it. , At the same time, it can take away the dust particles. The whole system has three functions of screening, drying and winnowing. The shale is heated by the hot flue gas at 300°C, the temperature is raised, and part of the external water is removed, so that the water content of the shale is reduced from 9% to 1%, and the temperature of the shale is raised from the ambient temperature to 80°C to ...

Abstract

The invention discloses a granule shale gas heat carrier destructive distillation technology. The technology comprises the steps of raw ore treatment, dry air classification, destructive distillation oil refining, product recovery and incineration heat obtaining. The heat recovery technological measures such as dry air classification and incineration heat obtaining are added, heat generated by burning oil shale semicoke is thoroughly recovered and applied to the whole process of destructive distillation heat consumption, heat efficiency is greatly improved, production cost is reduced, and the granule shale gas heat carrier destructive distillation technology is made to mature. The technological shortage of low heat efficiency is effectively overcome, output is larger than cost, benefits can be obtained through industrialization, the novel destructive distillation technology is developed, and the use ratio of resources is greatly increased.

Description

1. Technical field [0001] The invention belongs to the technical field of dry distillation process, and in particular relates to a dry distillation process of small particle shale gas heat carrier. The process can use the gas heat carrier technology to process small particle oil shale below 12mm in low temperature dry distillation to produce oil. 2. Background technology [0002] In the oil shale low-temperature retort technology, the development difficulty and process complexity of the small-particle oil shale retort technology are much greater than those of the massive shale retort technology. At present, the existing small particle oil shale carbonization technology in the world is solid heat carrier carbonization technology, and there is no mature industrial application of small particle gas heat carrier carbonization technology. The reason is that this process has low thermal efficiency and high production cost. 3. Contents of the invention [0003] The purpose of the...
