The starting and closing of door.
4. the automation continuous ion-exchange system according to claim 1 for extracting production for isoleucine scale, special
Sign is: the 0.4N hydrochloric acid tank (TN5) uses the dilute hydrochloric acid of 0.4Mol/L.
5. the automation continuous ion-exchange system according to claim 1 for extracting production for isoleucine scale, special
Sign is: the ion-exchange column shares 32, and 1-2 tons of resin useful load, ion-exchange column inlet and outlet are connect by pipeline with multiple-way valve, institute
Multiple-way valve is stated equipped with 32 imports for connecting ion-exchange column and 32 for connecting the outlet of ion-exchange column.
6. the control method that claim 1-5 any one automates continuous ion-exchange system, it is characterised in that it includes following step
It is rapid:
1) system process parameters are set by PLC controller；
2) PLC controller is acquired processing, and passes to flow sensor, pressure sensor, liquid level sensor data in system
It send to host computer；
3) operator passes through host computer, the operating status of monitoring system and each technological parameter, and according to authorization mechanism side
Just the operating parameter of system is configured；Including the pressure of system, flow, the multiple-way valve valve speed of service, stepping speed
Degree, systems exchange time, each column process station of system and each head tank, the material position of pans；
4) when abnormal conditions occurs in system, host computer can propose warning note to operator in time, using computer control
System is attached with the peripheral related system of client after system, to realize more control functions；
5) control system is monitored to pressure, flow, level parameter in technique；System program is according to technological parameter and technique
Control requires output to execute instruction to regulating valve and frequency converter execution；When occurring abnormal parameters in system operation, report in real time
Alert and stoppage protection；Real time monitoring and alarm are carried out to control system equipment hardware.
