Accompanying drawing explanation
Fig. 1 is the structural representation sketch of this utility model embodiment.
Detailed description of the invention
Below with reference to Figure of description and specific embodiment, this utility model is described in further details.
As shown in Figure 1: a kind of hplc grade methanol polishing purification device, reactor 1, the adsorber 2 being filled with molecular sieve and the rectifying column 3 connected including pipeline successively.Reactor 1 is for distilling methanol in a heated condition, the boiling point utilizing each component of liquid mixture is different, the material elder generation generating gasification making liquid mixture mid-boiling point low by heating becomes steam, and the higher liquid substance of boiling point remains as liquid, vapo(u)rizing temperature is arranged on about the boiling point of methanol by the present embodiment, so that more than methanol boiling point impurity after distillation or liquid, methanol and become gas the most after distillation less than the impurity of methanol boiling point, enter in the adsorber 2 being filled with 5A molecular sieve, thus realize methanol and separate with high-boiling-point impurity.It is filled with the adsorbable any molecule less than this aperture of adsorber 2 of 5A molecular sieve, the impurity such as the most adsorbable C3 C4 n-alkane, ethyl chloride, bromoethane, butanol, further up to the purification purpose of methanol, the methanol vacuum after filtering the most again is evacuated in rectifying column 3 by charging aperture 31.Wherein, the outlet of reactor 1 connects the feeding mouth of the second reboiler 4, the air intake of the discharging opening coupled reaction still 1 of the second reboiler 4 through delivery pump 11 so that the liquid of reactor 1 bottom enters after the second reboiler 4 becomes gas and enters back in reactor 1, carry out distillation circulation, economize in raw materials.
3 sides of rectifying column are provided with charging aperture 31, and inside is provided with packing layer 32, and top is provided with gas outlet 33, and bottom is provided with liquid outlet 34.Being provided with chuck 6 outside the middle and lower part of rectifying column 3, chuck 6, built with heater 61, is provided with heat-insulation layer 62 outside heater 61；The side of chuck 6 is provided with water inlet 63 and outlet 64.The side of chuck 6 is additionally provided with temperature sensor, for detecting the temperature in rectifying column 3, prevents from causing the injuries such as blast owing to temperature is too high；Temperature sensor electrical connection controller；Controller in the present embodiment is PLC.The gas outlet 33 of rectifying column 3 connects cooler 5 through valve, and liquid outlet 34 pipeline connects methanol storage drum；The outlet of cooler 5 connects the feeding mouth of the first reboiler 7, and the discharging opening of the first reboiler 7 connects the air intake of rectifying column 3.
The operation principle of the present embodiment is: during work, first in chuck 6, it is passed through water, heater 61, being heated to design temperature, design temperature controls make methanol and boiling point reach in the critical point of gas-liquid separation less than the impurity of methanol, is then pumped into by material in the packing layer 32 of rectifying column 3 from charging aperture 31, low boiling component is walked by the thermal evaporation top toward rectifying column 3, methanol is then cooled to liquid, flows in methanol storage drum through the liquid outlet 34 of rectifying column 3, thus obtains high purity methanol；Low boiling component then through gas outlet enter cooler 5, cooled become liquid after enter the first reboiler 7 in become gas, enter back in rectifying column 3, carry out rectification circulation, economize in raw materials.
The present embodiment is by arranging reactor 1, the adsorber 2 being filled with molecular sieve and rectifying column 3, it is ensured that other components are sufficiently separated, and then obtains high purity methanol, simultaneously works as the effect of rectification multiple product；By arranging the first reboiler 7 and the second reboiler 4, it is achieved distillation or rectification circulation, it is greatly saved raw material, reduces environmental pollution；Heat by arranging chuck 6, the inner space of rectifying column can be greatly saved, reduce overall volume.
