One-key extraction system and method

Abstract

The invention belongs to the technical field of extraction, and particularly relates to a one-key extraction system and method. The one-key extraction system comprises an extraction machine, and alsocomprises a heavy phase source, a light phase source, a heavy phase collection device and a light phase collection device which are connected to the extraction machine through pipelines, wherein the heavy phase source is connected to the heavy phase inlet of the extraction machine, the light phase source is connected to the light phase inlet of the extraction machine, the heavy phase collection device is connected to the heavy phase liquid outlet pipe of the extraction machine, and the light phase collection device is connected to the light phase liquid outlet pipe of the extraction machine. According to the system, after an extraction starting program is started, automatic interlocking control over the processes of a self-checking stage, an extraction or washing or reverse extraction stage, a stopping stage, a residual liquid treatment stage and a cleaning stage is achieved, transition between the processes does not need manual participation, and relevant working data are collected and calculated, so that program logic control is achieved, online parameter setting can be conducted, automatic and intelligent operation of the extraction system is achieved, and datamation of the operation process is achieved.

Description

technical field [0001] The invention belongs to the technical field of extraction, and in particular relates to a one-button extraction system and an extraction method. Background technique [0002] As an important unit process for separating and purifying substances, extraction technology is developing rapidly and its application is becoming wider and wider. Centrifugal solvent extraction is widely used in petrochemical, hydrometallurgy, fine chemical, biological, pharmaceutical and other fields due to its advantages of high efficiency, fast phase separation, airtight and continuous. As the core equipment of the centrifugal solvent extraction method, the centrifugal extractor has been innovated and developed from structural type to technical parameters. [0003] When the centrifugal extractor is running, because the two-phase balance with different densities is involved inside, when starting up, in order to quickly achieve phase balance, there are requirements for the feed...

AI Technical Summary

Problems solved by technology

At present, most centrifugal extractors and multi-stage extraction systems are in the stage of manual control. Even in the part of feed flow control, when applied to closed-loop automatic control, it is still partially interlocked after manual jogging, and the degree of manual participation is high, which is not in line with today's industrial The requirements of the production process need to be solved urgently. At the same time, due to the many steps of manual participation, the operation process cannot be saved in data, and the traceability of the process cannot be realized.
