Abstract
The utility model discloses a device for synthesizing lithium hexafluorophosphate, comprising a reactor body, wherein a polytetrafluoroethylene coating is arranged on the inner wall of the reactor body to avoid the corrosion on the wall of a steel container, thereby eliminating the phenomenon that the content of lithium hexafluorophosphate metal ions are increased due to the corrosion. The periphery of the reactor body is set into a jacket structure; the thickness of the polytetrafluoroethylene coating is 10-20 mu m and is smaller, so that the polytetrafluoroethylene coating is beneficial to heat transfer; and the utility model solves the problems that the traditional reaction device has high investment and energy consumption caused by poor heat transfer.
Description
Technical field
The utility model relates to a kind of device of synthetic hexafluorophosphate, relates in particular to a kind of synthesizer of lithium hexafluoro phosphate.
Background technology
Lithium hexafluoro phosphate is mainly as lithium ion battery electrolyte materials, its production method generally adopts the hydrogen fluoride solvent method, the reaction of the synthetic lithium hexafluoro phosphate of cause is to react under the anhydrous hydrogen fluoride system, there is hydrogen chloride gas in the system simultaneously, the equipment erosion resistance is had relatively high expectations, the production equipment that adopts is the stainless steel equipment material at present, generally selects 316L or Monel metal for use.Under complete anhydrous environment, can satisfy lithium hexafluoro phosphate synthetic needs, but do not open the moisture of the existence trace of avoiding in the reaction system, can produce corrosion to wall, long-time use finally can cause lithium hexafluoro phosphate metal ion neutralization product content to raise relatively, thereby reduced the lithium hexafluoro phosphate quality product, even produced substandard product.For avoiding occurring this situation, the someone adopts lining tetrafluoroethylene or full tetrafluoroethylene material to replace stainless steel cauldron, but since the heat transfer coefficient of tetrafluoroethylene class material far below stainless steel, heat-transfer effect is bad; Reach the heat transfer capacity the same, just must increase the heat transfer area of reaction vessel, can bring problems such as facility investment is big, energy consumption height with stainless steel.
The utility model content
The purpose of this utility model is the device that is to provide a kind of corrosion-resistant, synthetic lithium hexafluoro phosphate that heat-transfer effect is good.
To achieve these goals, the technical solution of the utility model is to adopt a kind of device of synthetic lithium hexafluoro phosphate, comprises reactor body, is provided with polytetrafluorethylecoatings coatings at the reactor body inwall.
The thickness of described polytetrafluorethylecoatings coatings is 10-20 μ m.
Be provided with jacket structured in the reactor body periphery.
Be provided with drain hole in the reactor body bottom, inlet mouth is arranged on the bottom of reactor body.
One charging opening is arranged at the reactor body top, and upper portion side wall is provided with waste gas outlet.
Reactor body is provided with temperature or pressure survey open holes.
The device of the synthetic lithium hexafluoro phosphate of the utility model, comprise reactor body, be provided with polytetrafluorethylecoatings coatings at the reactor body inwall, avoided corrosion, thereby eliminated the phenomenon of the lithium hexafluoro phosphate metal ion rising that causes because of corrosion the steel wall; The reactor body periphery is set to jacket structured, and the thickness of polytetrafluorethylecoatings coatings is 10-20 μ m, and is thinner, helps conducting heat, and solved traditional reaction unit because of the problem that the bad facility investment that brings is big, energy consumption is high of conducting heat.Using device of the present utility model to react with common unit compares: use after one month, metal ion reaches 5-10ppm in the use common stainless steel reactor synthetic lithium hexafluoro phosphate, even higher, has had a strong impact on the lithium hexafluoro phosphate quality; Metal ion still is less than 2ppm in the reactor synthetic lithium hexafluoro phosphate described in the utility model and use.
