Oil sand dry distilling system

Abstract

The invention relates to the technical field of dry distilling equipment and provides an oil sand dry distilling system. The oil sand dry distilling system comprises a feeding system, a drying and cooling system, a dry distilling and heat supply system, a dry distilling gas treating and recycling system, a flue gas treating system, an oil storage system and a circulating water system, wherein the feeding system comprises a raw material feeding device and a raw material storing device; the drying and cooling system comprises a scraper dryer; the dry distilling and heat supply system comprises a dry distilling device and a heat supply mechanism; the dry distilling gas treating and recycling system comprises a heating area dry distilling gas treating recycling device and a dry distilling area dry distilling gas treating recycling device; the flue gas treating system comprises a wet dust collector; the oil storage system comprises an oil storage tank used for storing end product of oil; the circulating water system comprises a centrifugal water pump and a water reservoir; and the continuous dry distilling for the oil sand is realized, the dry distilling speed is high, the energy consumption is low and the service life of the system is prolonged.

Description

technical field [0001] The invention relates to the technical field of dry distillation process equipment, in particular to an oil sand dry distillation system. Background technique [0002] The extraction of oil from oil sands, oil sludge, and oil shale, as the development of unconventional oil and gas and new energy sources, is of great significance and has broad prospects. The world is rich in oil sand resources, mainly distributed in Canada, the United States, Russia, Indonesia, Venezuela and China. China's oil sands and oil shale is also one of the most abundant countries in the world, ranking fifth in the world, with a preliminary estimate of 100 billion tons. The prospective resources of oil sands are about 10 billion tons, mainly distributed in Xinjiang, Qinghai, Tibet, Sichuan, Guizhou, Guangxi, Zhejiang and Inner Mongolia. Oil sand resources are distributed in all oil and gas basins. Among them, the Junggar Basin, the Tarim Basin, the Qaidam Basin, the Songliao ...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic oil sand carbonization is currently using small-capacity, intermittent rotary furnaces, and there are 5T, 10T and other models for one-time charging. From charging, ignition and heating, carbonization, furnace cooling to the end, the efficiency is low, the fuel consumption is large, and the production The cost is high, the external heating directly burns the furnace body, so that the furnace body and transmission parts operate at high temperature, the furnace body is cold and hot alternately, the life of the equipment is short, the rotating parts are prone to problems, the operation is unstable, and the maintenance rate is high

Blast furnace oil refining is only used for massive oil shale treatment, and it is still blank for dry distillation of oil sands.
