The specific embodiment
The import of separate raw materials pump (12) is connected with separate raw materials jar (7), and outlet links to each other with the import of each chromatographic column, and the import of eluant, eluent pump (13) is connected with eluant, eluent jar (8), exports to link to each other with the import of each chromatographic column.The outlet of a last root chromatogram column connects threeway and four-way, and one of them connects the import of next root chromatogram column, and one links to each other with preceding impurity storage tank (9), and one links to each other with middle main component storage tank (10), and one links to each other with rear impurity storage tank (11).The import of circulating pump (14) links to each other with the outlet of VI chromatographic column, and outlet links to each other with the import of I chromatographic column.All connecting lines (17) all select for use stainless steel tube to connect, the import of each chromatographic column, outlet all are connected with internally piloted valve (15), all internally piloted valves are connected with computer system by data wire with circulating pump (14), in computer system PLC program, configure the switch time and order of each internally piloted valve and circulating pump (14), the inlet of the outlet of separate raw materials pump (12), eluant, eluent pump (13) and preceding impurity storage tank (9), middle main component storage tank (10), rear impurity storage tank (11) all is equipped with flowmeter (16), indication flow size; The outlet of separate raw materials pump (12), eluant, eluent pump (13), the import and export of circulating pump (14) and the outlet of each chromatographic column all are equipped with Pressure gauge (18), indicated pressure size.
During work, adopt discontinuous charging and discharging, the mode of discontinuous complete alternation liquid stream is moved, and on traditional simulation moving-bed Equipment Foundations, each step of separating in the past is divided into three present sub-stepping row:
1, charging, extraction step: advance raw material and eluant, eluent, extract anterior impurity out;
2, the complete alternation step: chromatogram column system carries out complete alternation;
3, the wash-out step: advance eluant, eluent, wash out rear portion impurity.
Like this, during operation, drive separate raw materials pump (12) and eluant, eluent pump (13), advance separate raw materials from the import of III chromatographic column, advance eluant, eluent from the import of I chromatographic column, go out preceding impurity component from the outlet of I chromatographic column, enter in the preceding impurity storage tank (9), go out the rear impurity component from the outlet of V chromatographic column, enter in the rear impurity storage tank (11), the time of being advanced separate raw materials and eluant, eluent by the PLC procedure auto-control of computer is 350 seconds, time then, close separate raw materials pump (12) and eluant, eluent pump (13), by the PLC procedure auto-control open cycle pump (14) of computer and all internally piloted valves on the pipeloop, time is 650 seconds, system is in the complete alternation state, at this moment, neither also not discharging of charging, time then, close circulating pump (14), drive eluant, eluent pump (13), advance eluant, eluent from the import of II chromatographic column, go out middle main component from the outlet of I chromatographic column, enter in the middle main component storage tank (10), the time of being advanced eluant, eluent by the PLC procedure auto-control of computer is 40 seconds, time is then driven separate raw materials pump (12), advances separate raw materials from the import of IV chromatographic column, advance eluant, eluent from the import of III chromatographic column, impurity component before going out from the outlet of II chromatographic column before entering in the impurity storage tank (9), goes out the rear impurity component from the outlet of VI chromatographic column, enter in the rear impurity storage tank (11), by such reruning, preceding impurity in the separate raw materials and rear impurity be to the operation of the front and back of the main component in centre, we just can from corresponding outlet continuously extracting go out preceding impurity and rear impurity, middle main component is extracted when advancing eluant, eluent, reaches the purpose of separation of tertiary component with this.
