| titleOfInvention | A kind of combined type trace extraction device that liquefies step by step |
| abstract | The present invention relates to a kind of combined type trace extraction device that liquefies step by step, comprise gas storage steel cylinder, be provided with more than three; High-pressure liquefaction device, is connected with gas storage steel cylinder; Extraction column, is connected with high-pressure liquefaction device; Splitter, is connected with extraction column; Vavuum pump, is connected with splitter; Glass collector, has two, and each glass collector is only arranged in layered evaporator, and this layered evaporator is connected with splitter by triple valve; Gas trapping bubble gauge, has two, is connected respectively, and carries out gas instruction by throttle capillary tube with two layered evaporators; Immiscible liquid pipe, has two, is connected respectively with two gas trapping bubble gauges. Compared with prior art, the present invention utilizes the pressure of extractant and nitrogen, replaces compressor by supercharging mode step by step, has ensured the purity of extractant; Pressure when controlling extractant gaseous state, accurately controls the consumption of extractant, to reduce the consumption of extractant. |
