Description

Technical Field

[0001] The utility model relates to the technical field of purification devices, in particular to a hydrogen fluoride gas purification device. Background Art

[0002] Hydrogen fluoride (chemical formula: HF) is a binary compound composed of fluorine and hydrogen. Its English name is hydrogenfluoride. It is a colorless gas with a pungent odor [1]. Hydrogen fluoride is a monobasic weak acid. Hydrogen fluoride and its aqueous solution are toxic and can easily cause bone and tooth deformities. Hydrofluoric acid can penetrate the skin and be absorbed by the mucous membranes, respiratory tract, and gastrointestinal tract. In case of poisoning, emergency treatment should be carried out immediately and medical treatment should be sought. When mixed with antimony pentafluoride, fluoroantimonic acid (HSbF6) is generated, but some fluorides can protect teeth.

[0003] After searching, the existing Chinese patent announcement number is: CN 210356662 U, which provides a hydrogen fluoride gas purification device. The patent discharges through an exhaust hole. Since the porous plate where the exhaust hole is installed is located in the sodium hydroxide solution, the hydrogen fluoride in the flue gas can fully contact with the sodium hydroxide to achieve a better purification effect.

[0004] Although the above patent allows the hydrogen fluoride in the flue gas to fully contact with the sodium hydroxide to achieve a better purification effect, the above hydrogen fluoride gas purification device still has the following problems: since the exhaust hole is in an open state, it is easy for the sodium hydroxide or the stock solution to enter the interior of the porous plate, thereby causing the stock solution or the sodium hydroxide solution to accumulate inside the porous plate, thereby affecting the use effect of the porous plate in the later stage.

[0005] In view of the above problems, a hydrogen fluoride gas purification device is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a hydrogen fluoride gas purification device that can solve the problems of the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydrogen fluoride gas purification device, comprising a purification box, a sewage pipe is fixedly installed at the bottom of the purification box, the sewage pipe is connected to the interior of the purification box, a gas pipeline is fixedly installed inside the purification box, one end of the gas pipeline passes through the purification box and extends to the outside of the purification box, a rough purification device is arranged on the gas pipeline, a motor is fixedly installed on the top of the purification box, the output end of the motor rotates to pass through the purification box and extends to the interior of the purification box, a stirring shaft is fixedly installed on the output end of the motor, a porous box is fixedly installed on one end of the gas pipeline extending to the interior of the purification box, the porous box is fixedly connected to the interior of the purification box, the porous box and the gas pipeline are connected to each other, a sealing cover is fixedly installed on the porous box, and the sealing cover is connected to the interior of the porous box.

[0008] Preferably, two fixing rods are fixedly installed inside the porous box, and a lifting plate is slidably connected to the surface of the two fixing rods, and the lifting plate is slidably connected inside the porous box.

[0011] Preferably, the lifting plate is internally rotatably connected with a lifting connection pipe, and the lifting connection pipe is movably connected to the inside of the porous box and the sealing outer cover.

[0012] Preferably, a sealing block is fixedly mounted on the upper end of the lifting connecting pipe, the sealing block is located inside the sealing outer cover, and an exhaust hole is opened on the sealing block.

[0013] Preferably, a sealing ring is fixedly sleeved on the surface of the sealing block.

[0014] Preferably, the sealing block is fixedly connected to a fixed shaft, and the fixed shaft is fixedly mounted with blades.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

At the same time, the exhaust hole is sealed, thereby preventing the original liquid from entering the interior of the porous box and reducing the residual original liquid in the porous box.

[0025] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0026] See also Figure 1-4The utility model provides a technical solution: a hydrogen fluoride gas purification device, including a purification box 1, a sewage pipe 5 is fixedly installed at the bottom of the purification box 1, the sewage pipe 5 is connected to the interior of the purification box 1, a gas pipeline 3 is fixedly installed inside the purification box 1, one end of the gas pipeline 3 passes through the purification box 1 and extends to the outside of the purification box 1, a rough purification device 4 is arranged on the gas pipeline 3, a motor 2 is fixedly installed on the top of the purification box 1, the output end of the motor 2 rotates and passes through the purification box 1 and extends to the interior of the purification box 1, and a stirring shaft 6 is fixedly installed at the output end of the motor 2.

[0027] When the stock liquid in the purification box 1 is stirred, the motor 2 is started to drive the stirring shaft 6 to rotate, and then the stirring shaft 6 is used to stir the stock liquid and the flue gas so that the stock liquid and the flue gas are evenly mixed and the two react fully. Finally, the purified flue gas is discharged from the outlet to meet the flue gas emission standards.

[0028] A porous box 7 is fixedly installed on one end of the gas pipeline 3 extending to the inside of the purification box 1. The porous box 7 is fixedly connected to the inside of the purification box 1. The porous box 7 and the gas pipeline 3 are communicated with each other.

Lifting plates 13 are slidably connected on the surfaces of the two fixed rods 14. The lifting plates 13 are slidably connected inside the porous box 7. Elastic springs 15 are movably sleeved on the two fixed rods 14. The two elastic springs 15 5 is fixedly connected to the inside of the porous box 7, the lower ends of the two elastic springs 15 are fixedly connected to the top of the lifting plate 13, the lower ends of the two fixing rods 14 are fixedly installed with fixing plates 16, the lifting plate 13 is rotatably connected to the inside of the lifting connection pipe 12, the lifting connection pipe 12 is movably connected to the inside of the porous box 7 and the sealing outer cover 11, the upper end of the lifting connection pipe 12 is fixedly installed with a sealing block 10, the sealing block 10 is located inside the sealing outer cover 11, the sealing block 10 is provided with an exhaust hole 18, and a sealing ring 17 is fixedly sleeved on the surface of the sealing block 10.

[0032] Working principle:

[0033] When gas is injected into the porous box 7, as the air pressure inside the porous box 7 increases, the lifting plate 13 moves upward, and then the lifting plate 13 slides on the two fixed rods 14, squeezing the two elastic springs 15, driving the multiple lifting connecting pipes 12 to move upward, so that the sealing block 10 is no longer located inside the sealing outer cover 11, and the gas is discharged through the lifting connecting pipe 12, the sealing block 10 and the exhaust hole 18. When smoke is no longer introduced into the porous box 7, the air pressure inside the porous box 7 is reduced, and the lifting plate 13 is reset by the elastic force of the elastic springs 15, so that the sealing block 10 and the sealing ring 17 enter the inside of the sealing outer cover 11, thereby sealing the sealing outer cover 11.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
