Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with specific embodiments.
[0027] See figure 1 As shown, as a preferred embodiment, a parallel circulation type fluorination electrolytic cell is provided with at least two electrolytic cells 11, 21, and the circulation pump 16 adopted between the two electrolytic cells 11, 21 is made of anhydrous HF resistant material, The circulation pump 16 circulates the HF in the electrolytic tank and the materials dissolved in it, increases the contact probability of the materials and the plate, and thus greatly improves the efficiency of electrolytic fluorination.
[0028] Electrolyzer 11,21 and electrolyzer cover plate 5,28 are circular or rectangular structure, adopt low-carbon steel to make; Material pipe 4,34 and discharge pipe 13,20, discharge valve 12,18 is arranged on discharge pipe 13,20; Feed pipe 4,34 is the inlet of HF and material; Discharge pipe 13,20 is electrolytic fluorine The disc...

The invention relates to a parallel circulating fluorination electrolysis bath which is characterized by comprising two or more electrolysis baths, wherein pole plate assemblies are respectively installed in each electrolysis bath; each pole plate assembly is provided with nickel anode-iron cathode columns which are connected to positive and negative poles of an eliminator supply; the bottoms of the two electrolysis baths have a certain height difference; the fluorination organic matters with higher boiling point on the bottom of the second electrolysis bath automatically flow into the bottom of the first electrolysis bath through a fluoride return pipe, so that the materials are subjected to fluorination in a relay mode, thereby shortening the reaction induction period; a circulating pump is arranged between the two electrolysis baths, a circulating pipe connects the circulating pump respectively to the middle parts of the insides of the two electrolysis baths, and the circulating pump is used for enabling HF in the electrolysis baths and materials dissolved in the HF to flow circularly, thereby increasing the contact probability between the materials and the pole plates; the parallel circulation greatly enhances the electrolytic fluorination reaction efficiency and prevents the dead bath phenomenon; and the parallel electrolysis baths prolong the continuous working time of electrolysis, reduce the material consumption and lower the labor intensity of manual bath cleaning.
Description
Technical field [0001] The present invention involves the electrolyte electrolyte of the Organization and Electrical Electrical Electrical Electrical Electrical Electricity, which specifically involves a parallel cycling fluoride electrolytic groove. Background technique [0002] Chemical fluoride methods are prepared for organic fluoride, and F can be used 2 Direct fluoride, you can also use XEF 2 , Simboly, high -priced metal fluoride, N 2 The method and conditions required for the indirect fluoride method of Fluoride reagents such as class F compounds are more complicated and harsh, and the reactions and operations are quite complicated, and it is difficult to control the amount of fluoride organic compounds.The cost of fluoride used is high and toxic, and it is extremely unsafe. [0003] Simons electrochemical fluoride (ECF) method uses hydrogen -free hydrogen to produce whole fluoride or partial fluoride organic compounds.Instantly install a set of Ni anode and FE cathode i...
