Automatic control system and automatic control method for monosodium glutamate production resin column decolorization

Abstract

The invention provides an automatic control system for monosodium glutamate production resin column decolorization. The top of a resin column decolorization tank is communicated with a feeding main pipe and a backwashing discharging pipe, and the bottom of the resin column decolorization tank is communicated with a backwashing feeding pipe and a discharging main pipe; the feeding main pipe is communicated with a feeding communicating pipe, the feeding communicating pipe is provided with a feeding regulating valve and a feeding flow meter, and then is respectively communicated with a clear water / white crystal / hot water feeding pipe, the backwashing feeding pipe is communicated with a backwashing air feeding pipe and a backwashing communicating pipe, the backwashing communicating pipe is communicated with the end, close to the feeding regulating valve, of the feeding communicating pipe, a discharge regulating valve, an online detector and a discharge flow meter are arranged on the discharging main pipe, and the tail end of the discharging main pipe is communicated with a pressure column water discharge pipe, a white crystal discharge pipe and a drainage pipe. The invention further provides an automatic control method for monosodium glutamate production resin column decolorization. The method comprises the following steps: white crystal column loading, white crystal column pressing, one-time and few-time column loading, one-time and few-time column pressing, resin column backwashing, saline water regeneration, saline water washing and the like. Automatic control of resin column decolorization is realized, and the automation level, the production stability and the product quality of the decolorization process are greatly improved.

Description

technical field [0001] The invention relates to the technical field of monosodium glutamate production, in particular to an automatic control system using a resin column decolorization process in a monosodium glutamate production process, and an automatic control method using the system. Background technique [0002] At present, the domestic monosodium glutamate production process mainly uses resin columns for decolorization. The main process of the general resin column decolorization process is: material loading to the column (materials include white crystal, one-time needle, and less-time needle), material pressure column, backwash, acid Wash, brine regeneration, wash brine. Among them, the white crystal is a sodium glutamate solution formed after the neutralization of glutamic acid and soda ash, and its light transmittance is usually ≥ 95%; the white crystal enters the crystallization tank after decolorization, and the mother liquor obtained by crystallization and solid-l...

Problems solved by technology

[0004] In order to improve the automation level of monosodium glutamate production and ensure the quality of products, the present invention provides a monosodium glutamate production resin column decolorization automatic control system and the automatic control method implemented by the automatic control system, which solves the key process parameters of monosodium glutamate resin column light transmission The problem of online detection of degree and Baume degree can realize the automatic control of each process step in the resin column decolorization process, so that the resin column decolorization process avoids manual operation errors from the root, and removes the impact of manual operation on process stability and product quality. Adverse effects, greatly improving the automation level of the resin column decolorization process, greatly improving the process stability and product quality of the resin column, reducing the labor intensity of operators, and improving the economic benefits of the enterprise
