[0002] Hydrobromic acid is an important inorganic compound with a wide range of applications.

[0025] Working principle: First, the staff connects the pipe for discharging hydrobromic acid waste gas with the air intake pipe 4, so that the waste gas enters the air intake tube 2 through the air intake pipe 4, and the waste gas enters the activated carbon above the first air permeable plate 6 through the first air permeable plate 6, so that the activated carbon adsorbs and filters the harmful substances in the waste gas, and the filtered gas enters the exhaust pipe 8 through the second air permeable plate 10 just above the activated carbon, and is discharged from the exhaust pipe 7. When the activated carbon needs to be replaced, the staff starts the drive motor 13, so that the drive motor 13 drives the gear ring 15 to rotate through the gear 14, and the gear ring 15 drives the corresponding turntable 9 to rotate, and the turntable 9 drives Multiple baffles 11 rotate synchronously, and the baffles 11 drive another turntable 9 to rotate, so that the two baffles 11 above the first air permeable plate 6 push the used activated carbon toward the discharge barrel 16. At the same time, the slide groove on the turntable 9 drives the slide bar 20 to move, so that the slide bar 20 drives the second air permeable plate 10 to move synchronously through the support plate 17. As a result, the multiple second air permeable plates 10 and the baffles 11 on the turntable 9 can be replaced in position, and the activated carbon between the other two baffles 11 and the second air permeable plate 10 is aligned with the first air permeable plate 6 to ensure normal filtration of the exhaust gas. At the same time, the slide bar 20 moves along the inner side of the first arc-shaped groove 21. When the slide bar 20 moves to the end of the guide groove 23, the rebound force of the tension spring 19 is used to pull the slider 18 to move along the slide groove on the turntable 9, so that the slide bar 20 moves into the second arc groove 22. The slider 18 drives the second air permeable plate 10 to move between the two baffles 11 through the support plate 17, and pushes the used activated carbon into the discharge barrel 16 and contacts with the scraper 31. As the turntable 9 rotates, the scraper 31 scrapes the activated carbon on the second air permeable plate 10 into the discharge barrel 16 for discharge. When the second air permeable plate 10 is aligned with the lower barrel 5, the activated carbon in the lower barrel 5 can enter the second air permeable plate 10 and the two baffles. The activated carbon is arranged between the two baffles 11 to facilitate the replenishment of the activated carbon, and when the driving motor 13 rotates, the output end of the driving motor 13 drives the driven rod 24 to rotate synchronously through the synchronous belt 27, so that the driven rod 24 drives the stirring rod 26 on the mounting bar 25 to stir the activated carbon in the discharge barrel 5 to prevent the activated carbon in the discharge barrel 5 from agglomerating, so that the activated carbon can be evenly introduced between the second air permeable plate 10 and the two baffles 11. Therefore, with the intermittent rotation of the turntable 9, the activated carbon can be replaced, discharged and replenished, thereby achieving the effect of continuously treating the exhaust gas and ensuring the normal treatment of the exhaust gas during the production of hydrobromic acid.

A treatment method for an electronic-grade hydrobromic acid production waste gas treatment device according to any one of claims 1 to 9, characterized in that: The treatment method includes the following steps: S1: Filtration stage, the exhaust gas conveying pipe is connected to the air intake pipe (4), the exhaust gas is injected into the air intake cylinder (2), and the activated carbon between the first air permeable plate (6) and the second air permeable plate (10) adsorbs and filters harmful substances in the exhaust gas, and the filtered gas is discharged from the exhaust pipe (7); S2: During the material replacement phase, the driving motor (13) drives the gear ring (15) to rotate via the gear (14), and the second air permeable plate (10) and the baffle (11) between the two rotating disks (9) rotate, so that the other second air permeable plate (10) is aligned with the first air permeable plate (6); S3: in the discharge stage, the second air permeable plate (10) drives the slide bar (20) on the support plate (17) from the first arc-shaped groove (21) into the guide groove (23), so that the second air permeable plate (10) moves along between the two baffles (11) to put the used activated carbon into the discharge barrel (16); S4: During the replenishment phase, the driving motor (13) aligns the second air permeable plate (10) with the lower barrel (5), so that the activated carbon in the lower barrel (5) enters between the two baffles (11) and the second air permeable plate (10), thereby replenishing the activated carbon.
