Abstract
The invention discloses a technology for preparing fluorine gas through electrolysis of lithium fluoride-hydrogen fluoride, which is formed by a hydrogen fluoride storage tank, an electrolyte preparation vessel, an electrolytic cell, a dust catcher, a packed tower, a fire arrestor, a leaching tower and an air pump that are sequentially integrated through a connecting pipeline. The invention has reasonable design and simple structure, reduces the production cost, and is convenient to use.
Description
Affiliated technical field
The present invention relates to a kind of technology of preparing of Chemicals, particularly a kind of electrofluorination lithium one hydrogen fluoride prepares the technology 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 technology 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 by this invention is, overcomes the deficiencies in the prior art, provides a kind of electrofluorination lithium one hydrogen fluoride to prepare the technology of fluorine gas.This technology is not only reasonable in design, makes simply, and also easy to use, reduce production costs simultaneously.
The technical solution used in the present invention 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 technology 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 1kA.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 invention has the beneficial effects as follows that technology is reasonable, simple in structure, easy to use, reduce production costs, reduce environmental pollution.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
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 technology of fluorine gas, under 70-80 ℃ of temperature, realize as the method for ionogen system fluorine because of 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 1kA.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, after spark arrester 10 enters atmosphere, or after being further purified, super-dry and other equipment recycles.
