A kind of one-button extraction system and extraction method

Abstract

The invention belongs to the field of extraction technology, and specifically relates to a one-button extraction system and extraction method, including an extraction machine, and the system also includes a heavy phase source, a light phase source, a heavy phase collection device, a light phase Phase collecting device, wherein the heavy phase source is connected to the heavy phase inlet of the extractor, the light phase source is connected to the light phase inlet of the extractor, the heavy phase collecting device is connected to the heavy phase outlet pipe of the extractor, the light phase is collected The device is connected to the light phase outlet pipe of the extraction machine. After the extraction start procedure is started, the system realizes the automatic interlocking of the self-inspection stage, extraction or washing or back-extraction stage, parking stage, residual liquid treatment stage, and cleaning stage. Control, the transition between processes does not require manual participation, and at the same time collect and calculate relevant work data to realize program logic control and online parameter setting, so as to achieve automatic and intelligent operation of the extraction system and realize the control of the operation process. Digitization.

Description

One-click extraction system and extraction method technical field The invention belongs to extraction technical field, be specifically related to a kind of one-key extraction system and extraction method. Background technique Extraction is an important unit process for separating and purifying substances, and its technology is developing rapidly, and its application is also more and more more and more. Centrifugal solvent extraction is widely used in petrochemicals due to its advantages of high efficiency, fast phase separation, airtightness and continuity. Industry, hydrometallurgy, fine chemicals, biology, pharmaceuticals and other fields. Centrifugal extractor is the core design of centrifugal solvent extraction method. Equipment, from structural type to technical parameters, have been innovatively developed. When the centrifugal extractor is running, because the interior involves two-phase equilibrium with different densities, during startup, in order to quickl...

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.
