Abstract

The invention provides an oil extraction and slag removal method and system for a vertical tar-ammonia water separating process. The system comprises a mechanical slag scrapping tank, a tar-ammonia water separating tank used for receiving a mixture of tar, ammonia water and small-granule tar slag obtained in primary separation, a tar slag pump used for extracting the small-granule tar slag and the tar at the bottom of the tar-ammonia water separating tank, a secondary slag removal apparatus used for receiving the small-granule tar slag and the tar extracted from the bottom of the tar-ammonia water separating tank through the tar slag pump and carrying out secondary separation on the small-granule tar slag and the tar, a tar slag bucket used for receiving large granule tar slag obtained in primary separation and small-granule tar slag obtained in secondary separation and a tar intermediate tank used for receiving tar discharged from the secondary slag removal apparatus and having undergone secondary separation. The system has the advantages of convenience in extraction of the tar, good tar slag removal effects and capacity of thorough discharge of the small-granule tar slag from the system, so blockage of the system is avoided and production of the system is continuous and stable.

Description

technical field

[0001] The invention relates to a separation method and system, in particular to a method and system for oil recovery and slag removal in a vertical tar ammonia water separation process. Background technique

[0002] Because the vertical tar ammonia water separation process has the characteristics of large volume of separation equipment, long residence time and good separation effect, it has gradually replaced the traditional mechanized clarifier process in coal coking enterprises. Specifically, in the vertical tar ammonia water separation process, the mixture of tar, ammonia water and tar residue from the coke oven first enters the mechanized scraping tank, and the large particle tar residue is mechanically removed in the mechanized scraping tank. Then, tar, ammonia water and small particles of tar slag enter the tar ammonia water separation tank for static separation. Small particles of tar residue are deposited at the bottom of the tar ammonia water separa...
