Problems solved by technology

[0003] At present, the development and utilization of oil sands in the world is still in its infancy. Usually, the oil in the oil sands is recovered by chemical separation with a detergent containing strong alkali. Although the oil in the oil sands can be recovered with a strong alkali detergent, However, there are environmental pollution problems in the recycling process, and the recycling cost is high

Embodiment Construction

[0016] The present invention will be further described below in conjunction with drawings and embodiments.

[0017] A method for recovering hydrocarbon oil from oil sands is to send the oil sands into a closed container, and then stir the oil sands flowing in the closed container by mechanical rotation or oxygen-free gas blowing to make them appear In bulk form, inject oxygen-free gas at a temperature of 400-500°C into the container to vaporize the oil in the oil sand in the container, or directly heat the container to make the oil sand in the container reach a temperature of 400-500°C to make the oil The oil in the sand is gasified, and after the oil and gas flow out of the container, it is cooled to normal temperature to recover hydrocarbon oil.

[0018] refer to Figure 1-2 , the special equipment for the rotary kiln structure has a rotating kiln body 1, and a stirring piece 2 is welded on the inner wall of the rotating kiln body 1. The stirring piece 2 is a spiral piece, ...

Abstract

A method and special apparatus for recovering hydrocarbon oil from oil sand are disclosed. It is characterized by delivering oil sand into closed container, agitating for flowing oil sand by mechanical rotation and anaerobic gas blowing to disperse, injecting anaerobic gas at 400í½500íÒC into container, gasifying oil in oil sand or heating the container to gasify oil in oil sand at 400í½500íÒC, flowing the oil gas from container, cooling and recovering hydrocarbon oil. It is simple, convenient and costs low and has no environmental pollution.

Description

technical field [0001] The invention relates to a method and special equipment for recovering hydrocarbon oil from oil sand. Background technique [0002] Oil sand is an associated body of oil and sand, and has a wide range of reserves in the world. There are also large reserves in Xinjiang, Qinghai, Inner Mongolia and other places in my country. [0003] At present, the development and utilization of oil sands in the world is still in its infancy. Usually, the oil in the oil sands is recovered by chemical separation with a detergent containing strong alkali. Although the oil in the oil sands can be recovered with a strong alkali detergent, However, there is a problem of environmental pollution during the recycling process, and the recycling cost is high. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method for recovering hydrocarbon oil from oil sands with low recovery cost and no pollution to the environme...
