Abstract
The utility model relates to an electrolytic fluorine preparing acid dosing system which comprises a water heating cover, an HF (Hydrogen Fluoride) steel cylinder, an acid dosing pipeline, a bubble tube and a pressure stabilizing device, wherein the water heating cover is arranged on the HF steel cylinder, and an opening at one end of the acid dosing pipeline is connected with an outlet of the HF steel cylinder while an opening at the other end of the acid dosing pipeline is connected with the bubble tube. The pressure stabilizing device comprises a pressure stabilizing tube, an oil kettle and an oil overflow tube, wherein an opening at one end of the pressure stabilizing tube is communicated with the acid dosing pipeline while an opening at the other end of the pressure stabilizing tube is communicated with the top of the oil kettle, the oil overflow tube is vertically arranged on the oil kettle, and an opening at the bottom end of the oil overflow tube extends into the oil kettle. As the pressure stabilizing device is additionally arranged, in the acid dosing process, the pressure in the acid dosing pipeline can be stabilized through the pressure stabilizing device. When acidification is stopped and the pressure in the acid dosing pipeline decreases, fluorine oil in the oil overflow tube falls back to prevent an electrolyte from being absorbed in the acid dosing pipeline 4 to solidify to block the acid dosing pipeline, so that the blocking problem of the acid dosing pipeline is smoothly solved, and stable and continuous production is ensured.
