Embodiment Construction

[0008] In this method, the quantum particle swarm optimization algorithm is integrated with the simulated moving bed, and through the C-BUS system, the simulated moving bed can adaptively optimize the separation during operation.

[0009] The C-BUS system in the control method of the present invention is a two-wire management system, which controls and manages the simulated moving bed through the C-BUS system, so that the simulated moving bed can separate and purify products under various complex conditions.

[0010] All the unit devices in the simulated moving bed have built-in microprocessors and storage units except the power supply, and are connected to a network by a pair of signal lines (UTP5); each unit is set with a unique unit address and its function is set by software, through the output The unit controls the load of each circuit; the input unit establishes a corresponding relationship with the output component through the group address; when there is an input, the i...

Abstract

The invention discloses an intelligent control method for a simulated moving bed chromatographic apparatus. According to the method, a quantum-behaved particle swarm optimization algorithm and a simulated moving bed are subjected to embedded integration, and through C-BUS control, the simulated moving bed is allowed to self-adaptively carry out optimization and separation in the process of operation so as to reduce the complexity degree of separation of the simulated moving bed and improve a purifying effect on a product.

Description

technical field [0001] The invention relates to an intelligent control method for a simulated moving bed chromatographic device. Background technique [0002] Simulated moving bed (SMB) chromatographic separation technology is a modern separation technology, which has the advantages of strong separation ability, small equipment structure, low investment cost, easy to realize automatic control, and is conducive to the separation of heat-sensitive and difficult-to-separate substances. Preparative chromatography is most suitable for continuous large-scale industrial production. Simulated moving bed chromatography technology is an innovation of batch processing technology, so all fields that use simple batch processing chromatography, including biochemical plants, fine chemicals, pharmaceutical factories, oil factories, food factories and other chemical industries, are all applied in simulated moving bed chromatography market, but for enterprises, the simulated moving bed chrom...
