Full inert gas and pressurization discharge fluoboric acid liquid, while the water in plastics reactive tank 43 can also be pressurizeed by the first inert gas
Pipeline 495 is added in plastics reactive tank 43.
The bottom of air injection pipe 46 is provided with dispersion block 47, and dispersion block 47 is uniformly divided on dispersion block 47 by injection molding
It is furnished with the air hole 48 of supplied gas circulation, air flow sensor 493 is provided in air injection pipe 46, for detecting the stream of hydrogen fluoride
Speed controls the process of reaction, and the part that air injection pipe 46 and exhaust pipe 49 are located in groove body 4 is made of plastics, the bottom of air injection pipe 46
End is provided with the solenoid valve of control opening and closing lower than in plastics reactive tank 43 in air injection pipe 46 and exhaust pipe 49.
When purification boric acid is dissolved in the water in plastics reactive tank 43, purification boric acid has on the length direction of groove body 4
Multiple feed inlets 41, i.e. boric acid concentration in reactive tank uniformly improve, while air injection pipe 46 is on the length direction of groove body 4
Also have it is multiple, improve hydrofluoric acid dissolution in the rate in boric acid, can once generate a large amount of fluoboric acid, pass through air mass flow
Sensor 493 and temperature sensor 43 detect the temperature change in reaction process, in conjunction with the ice water in water cavity 44, improve fluorine boron
The concentration of acid;Exhaust pipe 49 and air injection pipe 46 made of plastics, reduce the corrosion of hydrofluoric acid;Pass through solenoid valve control simultaneously
The discharge of fluoboric acid and the recycling of pernicious gas in air injection pipe 46;Dispersion block 47 be in plastics reactive tank 43,
Etching acid gas is directly discharged into boric acid solution, etching acid is reduced and is directly entered in air, reduces etching acid leakage, leads to
The combination of dispersion block 47 and semicircular plastics reactive tank 43 is crossed, the contact area of etching acid and boric acid solution is improved, is improved molten
Solve effect.By being provided with water inlet 491 and water outlet 492, and then flowing water stream is produced in water cavity 44, so as to
Temperature in reaction process in plastics reactive tank 43 is reduced, the generation of the fluoboric acid in plastics reactive tank 43 is generated beneficial
Effect;Plastics reactive tank 43 has good anticorrosion effect, and the corrosion for avoiding hydrogen fluoride from generating reduces the service life of pan tank,
Semicircular plastics reactive tank 43 improves the contact area between 43 bottom of the ice water in water cavity 44 and plastics reactive tank, improves
Cooling effect controls whole reaction temperature at 40 DEG C;Air injection pipe 46 plays the work inputted hydrogen fluoride in groove body 4
With exhaust pipe 49 avoids the air pressure in groove body 4 from rising too high, and the first inert gas pressure pipeline 495 makes to guarantee inertia in groove body 4
Gaseous environment, the aerial concentration of Jiangdu hydrogen fluoride, boric acid is entered by feed inlet 41 falls into the plastics reactive tank equipped with water
In 43;The installation and use of plastics reactive tank 43 for convenience, plastics reactive tank pass through step 496 and block 497 simultaneously
Cooperation is fixed, and reacts the fluoboric acid of generation under the action of air pressure and gravity, flows outward from discharge port 42.
