Ion exchange automation control device, control method and control system

Abstract

The invention relates to an automatic ion exchange control device, a control method and a control system, an acid feeding pipeline, a conventional feeding pipeline and a reverse top liquid discharging pipeline are arranged at the top end of an ion exchange column, a bottom opening is formed in the bottom end of the ion exchange column, and a diluted hydrochloric acid pipeline and a diluted sulfuric acid pipeline are respectively communicated and connected with the acid feeding pipeline; the purified water pipeline and the extracting solution pipeline are respectively communicated and connected with the conventional feeding pipeline, the dilute caustic soda liquid pipeline, the desorption solution pipeline, the blow-off pipeline and the high ammonia nitrogen blow-off pipeline are respectively communicated and connected with the bottom opening, and the reverse jacking solution pipeline is communicated and connected with the reverse jacking solution discharging pipeline. Automatic feeding and metering are achieved through technological process control, purification and separation after regeneration of the ion exchange column and automatic column adsorption are achieved through forward and reverse automatic washing, fraction separation and collection of an extracting solution are achieved through analysis of an online analyzer, frequent field operation of operators is not needed, and the automation degree is high.

Description

Technical field[0001]The present invention relates to the field of biomedicine or food technology, and more particularly to an ion exchange automation control device and a control method and control system.Background technique[0002]The existing ion exchange process involves water washing, pickling, alkaline washing, upper column adsorption, analysis, fraction collection, etc., each step requires manual manual opening of the corresponding valve and regulates the valve opening control flow and pressure; not only Cleaning, upper column adsorption and analysis of the flow and pressure are also different, and base washing, water washing feed is from top to bottom and from bottom to the upper two. The operator is required to perform, frequently turned on, close, and adjust the valve; especially when the upper column adsorption process, the volume of the upper column needs to manually observe the volume of the recording tank, and if the distance between the storage tank and the ion exchang...

AI Technical Summary

Problems solved by technology

Operators are required to manually open, close and adjust valves frequently according to the process steps; especially during the column adsorption process, the volume of the column needs to be manually observed and recorded for the volume of the storage tank. If the distance between the storage tank and the ion exchange column is compared Personnel need to check back and forth; not only the workload is heavy, but also the work efficiency is not high; especially when working at night, it is easier to make mistakes and increase the risk of operational errors

More importantly, once the wrong valve is opened, it may lead to the loss of raw materials and products, which will not only reduce the yield of the process but also increase the cost of environmental protection treatment
