Embodiment Construction

[0014] See figure 1 , The continuous extraction device of this embodiment includes an extraction kettle 1 and a distillation kettle 2.

[0015] The extraction kettle 1 is provided with a feed inlet 11 , an outlet 12 for an extract and an outlet 13 for an extractant return. The still 2 is provided with an inlet 21 for extracting liquid, an outlet 22 for solute and an outlet 23 for steaming the extraction agent.

[0016] The extraction liquid outlet 12 of the extraction kettle 1 is connected with the extraction liquid inlet 21 of the still 2 through the extraction liquid pipe 3 . The extraction agent steam outlet 23 of the still 2 is connected with the extraction agent return port 13 of the extraction kettle 1 through the extractant pipe 4 .

[0017] The ratio of the distance H2 between the extraction solution outlet 12 of the extraction kettle 1 and the liquid level in the extraction kettle 1 to the distance H1 between the extraction solution outlet 12 of the extraction kettl...

Abstract

The invention discloses a continuous extraction device and a continuous extraction method adopting the continuous extraction device. The continuous extraction device comprises an extraction kettle and a distillation kettle, wherein the extraction kettle is provided with a material inlet, an extraction liquid outlet and an extraction agent liquid return opening, the distillation kettle is providedwith an extraction liquid inlet, a solute outlet and an extraction agent steaming outlet, the extraction liquid outlet of the extraction kettle is connected with the extraction liquid inlet of the distillation kettle through an extraction liquid pipe, the extraction agent steaming outlet of the distillation kettle is connected with the extraction agent liquid return opening of the extraction kettle through an extraction liquid pipe, and the ratio of the distance H2 from the extraction liquid outlet to the liquid surface of the extraction kettle to the distance H1 from the extraction liquid outlet to the extraction liquid inlet is equal to the density ratio of high-density extraction agents and low-density raw solvent. The continuous extraction device has the advantages that the whole extraction process can be continuously carried out, and the manual operation is not needed. In addition, through the design, the height of the whole extraction device can be reduced, and the requirement on production places is low.

Description

technical field [0001] The invention relates to a chemical unit operation equipment and method, in particular to a continuous extraction device and a continuous extraction method using the continuous extraction device. Background technique [0002] At present, many extraction equipment require manual operation, and continuous extraction cannot be performed, which greatly reduces the extraction efficiency. In addition, the height of the entire extraction equipment is very high, which requires high requirements for the production site. Contents of the invention [0003] One of the objectives of the present invention is to solve the above problems, and provide a continuous extraction device that does not require manual operation and has low requirements on the production site. [0004] Another object of the present invention is to provide a continuous extraction method using the continuous extraction device. [0005] The technical solution to realize one of the objectives o...
