Abstract
The utility model discloses a device for preparing fluorine by electrolyzing lithium fluoride and hydrogen fluoride. The device is mainly formed by integrally assembling a hydrogen fluoride storage cabinet, an electrolyte preparation tank, an electrolytic tank, a dust remover, a packed tower, a fire barrier, a leaching tower and an air pump through a pipeline in sequence. The device for preparing fluorine by electrolyzing the lithium fluoride and the hydrogen fluoride has the advantages of reasonable design, simple structure, convenience for use and low production cost.
Description
Technical field
The utility model relates to a kind of preparation facilities of Chemicals, and particularly a kind of electrofluorination lithium one hydrogen fluoride prepares the device of fluorine gas, is suitable for preparing fluorine gas, and can the on-the-spot fluorine gas of supply in time.
Background technology
At present, the device of preparation fluorine gas is direct electrolysis of hydrogen fluoride, and production efficiency of equipment is low, the cost height, and of poor quality, environmental pollution is serious.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiency of existing apparatus, provides a kind of electrofluorination lithium one hydrogen fluoride to prepare the device of fluorine gas.This device is not only reasonable in design, makes simply, and also easy to use, reduce production costs simultaneously.
The device scheme that the utility model adopts is: hydrogen fluoride storage cabinet, ionogen preparing tank, electrolyzer, fly-ash separator, packed tower, spark arrester, eluting column, aerator pump are assembled into one by the connection line order and constitute.
Adopt electrofluorination lithium one hydrogen fluoride to prepare the device of fluorine gas, the hydrogen fluoride of hydrogen fluoride storage cabinet is squeezed into the ionogen preparing tank through pump and is prepared, the ionogen for preparing is after the preelectrolysis dehydration, add lithium fluoride and be transferred to electrolyzer, electrolyzer progressively increases to rated current more earlier from low current 1 kA.By low-voltage rectifier supply direct current, if series design divides the voltage for each electrolyzer to be about 12V.Usually operating voltage is 8.5-10.5V, current efficiency 90%-95%.
The fluorine gas that anode electrolytic cell is separated out is after the fluorine gas pipe enters fly-ash separator and removes dust, enter the hydrogen fluoride packed tower and reclaim the hydrogen fluoride of carrying secretly, pass through eluting column again, remaining hydrogen fluoride is removed in Sodium Fluoride absorption, the fluorine gas of preparation enters basin, it is standby to charge into the fluorine gas steel cylinder through aerator pump, or directly delivers to next workshop section and produce other fluorochemicals.
The beneficial effects of the utility model are that technology is reasonable, and is simple in structure, easy to use, reduces production costs, and reduces environmental pollution.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Accompanying drawing number is: 1, hydrogen fluoride storage cabinet, 2, the ionogen preparing tank, 3, electrolyzer, 4, fly-ash separator, 5, packed tower, 6, eluting column, 7, the fluorine gas steel cylinder, 8, connection line, 9, aerator pump, 10, spark arrester.
Embodiment
With reference to Fig. 1, hydrogen fluoride storage cabinet 1, ionogen preparing tank 2, electrolyzer 3, fly-ash separator 4, packed tower 5, spark arrester 10, eluting column 6, aerator pump 9 are assembled into one by connection line 8 and constitute.
Adopt electrofluorination lithium one hydrogen fluoride to prepare the device of fluorine gas, under 70-80 ℃ of temperature, realize as the method for ionogen fluorine processed because utilizing this compound, the hydrogen fluoride of hydrogen fluoride storage cabinet 1 is squeezed into ionogen preparing tank 2 through pump and is prepared, the ionogen for preparing adds lithium fluoride and is transferred to electrolyzer 3 after the preelectrolysis dehydration.Electrolyzer 3 progressively increases to rated current more earlier from low current 1 kA.By low-voltage rectifier supply direct current, if series design divides the voltage for each electrolyzer to be about 12V.Usually operating voltage is 8.5-10.5V, current efficiency 90%-95%.
The fluorine gas that electrolyzer 3 anodes are separated out is after the fluorine gas pipe enters fly-ash separator 4 and removes dust, enter hydrogen fluoride packed tower 5 and reclaim the hydrogen fluoride of carrying secretly, pass through eluting column 6 again, remaining hydrogen fluoride is removed in Sodium Fluoride absorption, the fluorine gas of preparation enters basin, it is standby to charge into fluorine gas steel cylinder 7 through aerator pump 9, or directly delivers to next workshop section and produce other fluorochemicals.
The hydrogen that electrolyzer 3 negative electrodes are separated out is after the hydrogen pipe advances people's fly-ash separator 4 and removes dust, enter hydrogen fluoride packed tower 5 and reclaim the hydrogen fluoride of carrying secretly, remove remaining hydrogen fluoride through the sodium carbonate solution washing again, enter atmosphere finally by spark arrester 10, or after super-dry and other equipment are further purified, recycle.
Claims (1)
1. electrofluorination lithium one hydrogen fluoride prepares the device of fluorine gas, and it is characterized in that: hydrogen fluoride storage cabinet, ionogen preparing tank, electrolyzer, fly-ash separator, packed tower, spark arrester, eluting column, aerator pump are assembled into one by the connection line order and constitute.
