Abstract

The invention relates to a microwave-adsorption / desorption oil shale distillation methane light oil recovery device which is characterized in that oil-containing methane gas inlets on bottoms of two synchronous circulation tanks are respectively connected with an oil-containing methane gas source; methane gas outlets on tops of the two synchronous circulation tanks are respectively connected with a methane gas inlet of a methane gas storage tank; a methane gas outlet of the methane gas storage tank is respectively connected with methane gas inlets on tops of the two synchronous circulation tanks; oil-gas outlets on bottoms of the two synchronous circulation tanks are respectively connected with an inlet of a circulating pump; an outlet of the circulating pump is respectively connected with a methane gas inlet of the methane gas storage tank and a gas inlet on the top of a methane condenser; a gas outlet on the bottom of the methane condenser is connected with a methane gas inlet of the methane gas storage tank; an inlet and an outlet of a cooling circulation water pipe arranged in the methane condenser are respectively connected with a cooling tower; an oil discharge outlet of the methane condenser is connected with a light oil storage tank; the synchronous circulation tanks are respectively provided with a filler layer; the two synchronous circulation tanks are respectively arranged in a microwave generator; and the microwave generator is connected with a microwave heating controller.

Description

technical field [0001] The invention relates to the technical field of oil shale dry distillation and oil refining, and relates to a recovery device for microwave absorption and desorption of oil shale dry distillation gas light oil. Background technique [0002] Oil shale carbonization, that is, heating oil shale to the required temperature in an air-isolated environment, so that the kerogen undergoes pyrolysis reaction, and generates carbonization products-shale oil and carbonization gas. Shale oil can not only be used directly for marine use The liquid fuel used by turbines can also be produced through rectification process to produce liquid fuels such as gasoline and diesel. At present, the recovery of shale oil in the industry generally adopts the method of condensing and separating the retorted oil and gas, and cooling the retorted oil and gas to make the shale oil become liquid and precipitate, and the rest is non-condensable gas. Therefore, the lower the temperature...
