Problems solved by technology

In the past two years, there are two kinds of small particle retort devices researched in China. One is the DG technology of Dalian University of Technology, which also uses solid as the heat carrier, but has not yet built an industrial experimental device.

Embodiment Construction

[0014] Accompanying drawing 2 is the specific implementation device of this new process. The retort furnace is equipped with nine layers of reentrant vibrating beds, and the thermal cycle gas at 700°C enters from the lower part of the three-layer vibrating beds of 4, 5, and 6, so that the oil shale and gas gas in the retort furnace have a mixed flow. The height of the retort section is 4.5m-5m. The cold cycle gas enters from the lower part of the ninth vibrating bed, and cools the dry-distilled semi-coke to 250°C in a mixed flow state. The semi-coke falls into a closed water pool and is cooled to 80°C before being discharged out of the furnace.

Abstract

The invention relates to carbonization process and the device thereof which can treat short grain oil shale. A multilayer vibrated bed is used to convey material, a thermal cycling gas is used as gas heat carrier, and the material is carbonized under the working condition of repeated material interflow. The material and the gas heat carrier are not only vertically but also transversely contacted in a retort oven, the carbonization intensity is high, the time is short, and the oil yield is higher than 90 percent. The device has the advantages of simple structure, convenient operation, low investment and high efficiency.

Description

Technical field [0001] The invention relates to a technology and device for dry distillation of small particle oil shale under full circulation state using gas as heat carrier. During the process of vibrating, the oil shale is in full contact with the reverse hot gas to realize dry distillation. This device is suitable for processing small grain oil shale below 6mm. The daily processing capacity can be determined according to the needs, generally 2000-5000 tons. Background technique [0002] At present, most oil shale retorts at home and abroad are prone to furnace blockage and coking due to small particle shale, which makes the retort furnace unable to operate normally, so small particle oil shale is discarded. For example, the Fushun type retort furnace can only retort oil shale above 12mm. The resource waste rate reaches more than 20%, and causes environmental pollution. The Brazilian furnace (Petrosix) can only process shale above 6.4mm. There are two typical devices...
