Problems solved by technology

However, slow sampling will cause the current detection solution of the detection instrument to be the solution in the biochemical reactor some time ago, that is, the detection value has a large lag, and there is a certain error, which brings difficulties to the control and evaluation of the product.

Embodiment Construction

[0014] Attached below figure 1 And embodiment the structure of the present invention is described further.

[0015] Such as figure 1 As shown, the solid line is the pipeline, the dotted line is the communication line, the dotted line is the intermittent sampling path, and the arrow indicates the transmission direction of the signal or liquid. The equipment involved in the present invention includes: constant flow pump 2 (TBP1010), constant flow pump 3 (TBP1002), on-line sugar concentration analyzer 5 (YSI2700), self-made mixer 4, embedded module 1 (BL2100), touch screen 6 ( TPC7062K), high performance liquid chromatography 7 (HITACHI655). The constant flow pump 2 extracts the reaction solution through the pipeline, and the constant flow pump 3 is connected to pure water. The two liquids are fully mixed and diluted in the mixer 4 according to a certain ratio, and then through the online detection of the online sugar concentration analyzer 5, the detection result passes The R...

Abstract

The invention provides an on-line sugar concentration real-time detection system aimed at problems of low sampling speed of a small-scale biochemical reactor and lag of sugar concentration on-line detection. The system is mainly composed of an embedded module, a touch screen, a constant flow pump, an on-line sugar concentration analyzer, an off-line sugar concentration analyzer and the like. The touch screen is a man-machine interface and receives arrangement and operation of on-site personnel. The embedded module controls the flow rate of the constant flow pump and the action of the sugar concentration analyzers as a control unit of the system, collects the sugar concentration detection values of the on-line sugar concentration analyzer, performs on-line correction to the collected values, obtains accurate sugar concentration detection values in the biochemical reactor, and can amend model parameters according to the values of the off-line sugar concentration analyzer. The system integrates the information of the off-line analyzer and the on-line analyzer, combines the advantages of accuracy of off-line detection and real time of on-line detection, and is suitable for real-time detection of some small-scale biochemical reactors.

Description

technical field [0001] The invention relates to an on-line detection system of sugar concentration. Aiming at the problems of detection lag and the like in the application of an online sugar concentration detector in a small biochemical reactor, an on-line sugar concentration detection system based on correction of detected values ​​is designed. Background technique [0002] In biochemical reactions, sugar concentration is an important factor affecting biomass growth and directly determines the yield and quality of products, so accurate online detection of sugar concentration is very important. At present, most of the biochemical processes often adopt the method of offline sampling and analysis, which is time-consuming and laborious, and the sampling period is long, which cannot reflect the sugar consumption of biomass in real time, and is suitable for extensive biochemical production. In some refined production, it is generally equipped with advanced online detectors, but d...
