Tower head (3) is provided with helical form water pipe (16), cooling water inlet (10) and coolant outlet (11), tower head (3) highest point has tail gas outlet (12), tower head (3) right lower quadrant is connected to fluid collection tube (14), fluid collection tube (14) is communicated with by the surplus liquid return duct of tail gas (13) with tail gas outlet (12), and be connected to yaw discharging opening (15) in fluid collection tube (14) bottom, the lower left quarter of yaw discharging opening (15) flows the upper lateral part that pipe (17) feeds tower pipe (2) once.
Actinolyte (7) is installed on the axis of tower still (1).Whole removal rectifying column is the transparent body, all adopts quartz material.
The beneficial effects of the utility model are: can intuitive and convenient ground observe whole Impurity removal process, and carry out being lower than under 100 ℃ of temperature, simple in structure, easy to operate, safe and reliable, impurity removal efficacy is higher.
Description of drawings further describes its specific embodiment below in conjunction with accompanying drawing of the present utility model.
Fig. 1 is the rectifying column schematic diagram of CH and HCl impurity in the utility model removal germanium tetrachloride.
The tower of 1-shown in figure still, 2-tower pipe, 3-tower head, the 4-charging aperture, 5-gas supply mouth, 6-temperature monitoring mouth, the 7-actinolyte, 8-heating tube, 9-trash discharge mouth, the 10-cooling water inlet, 11-coolant outlet, the outlet of 12-tail gas, the surplus liquid return duct of 13-tail gas, 14-fluid collection tube, 15-yaw discharging opening, 16-helical form water pipe, the 17-return duct
The specific embodiment
Embodiment: rectifying column is made of the tower still 1 of bottom, the tower head 3 on top and the middle part tower pipe 2 of connection tower still 1 and tower head 3, is provided with heating tube 8 and actinolyte 7 in tower still 1.Leave charging aperture 4 and gas supply mouth 5 at tower still 1 top, have temperature monitoring mouth 6, have trash discharge mouth 9 in tower still 1 bottom at tower still 1 sidepiece.
Tower head 3 is provided with helical form water pipe 16, cooling water inlet 10 and coolant outlet 11, tower head 3 highest points have tail gas outlet 12, tower head 3 right lower quadrants are connected to fluid collection tube 14, fluid collection tube 14 and tail gas outlet 12 is communicated with by the surplus liquid return duct 13 of tail gas, and be connected to yaw discharging opening 15 in fluid collection tube 14 bottoms, the lower left quarter of yaw discharging opening 15 flows the upper lateral part that pipe 17 feeds tower pipe 2 once.
Whole rectifying column is transparent, all adopts quartz material.
During use, the germanium tetrachloride that needs are purified joins in the tower still 1 by charging aperture 4, after heating, process heating tube 8 makes germanium tetrachloride boiling volatilization, the germanium tetrachloride that evaporates rises by tower pipe (2) and arrives the tower head (3) on this rectifying column top, through helical form water pipe (16) condensation, condensed germanium tetrachloride and is collected or is back in the tower still 1 by return duct (17) by control yaw discharging opening (15) in the surplus liquid return duct of tail gas (13) influent collecting pipe (14).Removal of impurity technical process of the present invention can be in this rectifying column continuous repetitive cycling, impurity content reaches the germanium tetrachloride for optical fibre standard in germanium tetrachloride, carries out formal discharging and collects qualified products from yaw discharging opening 15.
Cooling water enters the circulation back from coolant outlet 11 discharges from the cooling import 10 of helical form water pipe (16).
