Embodiment Construction

[0022] Below in conjunction with the drawings, preferred embodiments of the present invention are given and described in detail.

[0023] Such as figure 1 As shown, the separation device for liquid hydrogen fluoride solution according to the present invention includes a jacketed sealed reactor 1 , a jacketed sealed collector 2 , a second absorber 3 and a pump 4 .

[0024] The jacketed sealed reactor 1 is fixed with a filter sleeve 11, the solid solute 12 and PTFE stirrer 18 are accommodated in the filter sleeve 11, and the liquid hydrogen fluoride 13 is introduced into the filter sleeve through the liquid inlet pipe 14 11 and under the action of the PTFE stirrer 18, the solid solute 12 is dissolved to form a liquid hydrogen fluoride solution 15, and the liquid hydrogen fluoride solution 15 passes through the filter membrane sleeve 11 and is exported through the outlet pipe 16. In addition, the jacketed sealed reactor 1 communicates with the atmosphere through the first pipeli...

Abstract

The invention relates to a separating apparatus for a liquid hydrogen fluoride solution. The separating apparatus comprises: a jacket type sealed reactor, wherein a filter membrane sleeve is fixedly arranged in the jacket type sealed reactor, the jacket type sealed reactor is communicated with atmosphere through a first pipeline, and the first pipeline is provided with a first absorber used for absorbing hydrogen fluoride gas; a jacket type sealed collector, which is communicated with a liquid outlet pipe through a second pipeline; a second absorber arranged at the lower stream of the jacket type sealed collector and used for absorbing hydrogen fluoride gas, wherein the second absorber is communicated with the jacket type sealed collector through a third pipeline and with the liquid outlet pipe through a fourth pipeline; and a pump arranged at the lower stream of the second absorber and used for generating negative pressure in the jacket type sealed reactor and the jacket type sealed collector. The invention further provides a separation method of the separating apparatus. The separating apparatus and method provided by the invention meet requirements for leakproofness, low temperature performance, safety and environmental protection of separating process for the liquid hydrogen fluoride solution.

Description

technical field [0001] The present invention relates to the separation of hydrogen fluoride solution, more specifically to a separation device and method for liquid hydrogen fluoride solution. Background technique [0002] Hydrofluoric acid is a colorless transparent fuming liquid, which is an aqueous solution of hydrogen fluoride gas, which is weakly acidic and has a pungent odor. Hydrofluoric acid can react with silicon and silicon compounds to generate gaseous silicon tetrafluoride (which can corrode glass), but it has no corrosive effect on plastics, paraffin, lead, gold, and platinum. [0003] In the electrolytic aluminum industry, hydrogen fluoride is used in the production of aluminum fluoride and cryolite, in the synthesis of chlorofluorocarbons for refrigerants and blowing agents, and in the synthesis of polymers. During the processing of uranium, hydrogen fluoride can convert uranium dioxide into uranium tetrafluoride and uranium hexafluoride, respectively, and ur...
