Embodiment Construction

[0016] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0017] The implementation process of the oil-coal slag extraction process of the present invention:

[0018] (1) Solvent extraction operation: open the feeding tank 19 and its valve 33 on the upper part of the extraction kettle 1, add Shenfu coal (bituminous coal) and benzene in the extraction kettle 1, close the feeding tank 19 and its valve 33, and then open the valves 21, 28 , 34, other valves are closed; open the magnetic stirrer 11 and adjust the rotation speed for extraction; when the extraction reaches equilibrium, close the magnetic stirrer 11 and close the valve 21.

[0019] (2) Extraction mixture separation operation: open valve 31, open water pump 5, make the water in the water tank 4 flow back in the water tank 4 through condenser 14 and condenser 7 again; Open valve 32,22,23,24,28, 34. Other valves are closed; turn on the air compression pump ...

Abstract

The invention relates to oil cinder extraction process and the device that adopts extraction kettle, evaporation kettle, solvent recycle kettle, solvent condenser, cooling water circulatory system, magnetic stirrer, and valve pipeline and controller platform. The extraction could take place of petrol and diesel oil after post process, or further separating into organic chemicals. It is low cost, safe to operation, low energy consumption, and has good cooling effect, high recycling ratio and could save solvent and water resource. The invention has great social and economic benefits.

Description

1. Technical field [0001] The invention relates to an oily coal residue extraction process and equipment, especially suitable for organic solvent extraction and separation of bituminous coal or lignite, liquefied coal residue and heavy oil residue, and also suitable for solid-liquid extraction process in petrochemical industry. 2. Background technology [0002] Fuel oil and petrochemical products are important substances related to the national economy and people's livelihood. At present, my country's dependence on oil imports is increasing, so the issue of energy security will directly affect the healthy development of my country's economy. my country is rich in coal resources, and liquid fuels that can replace petroleum can be synthesized through coal gasification; fuel oil or some organic chemicals can be obtained through coal liquefaction, such as tar obtained by coking technology can obtain many aromatic organic compounds, and aromatic compounds are used in the preparat...
