[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present invention: A flow control device inside a hydrogen fluoride device tower, including a reaction tower 1, a fixed plate 3 is fixedly connected inside the reaction tower 1, grooves 4 are respectively opened on the left and right sides of the top of the fixed plate 3, a partition plate 5 is fixedly connected to the top of the fixed plate 3, telescopic rods 6 are respectively fixedly connected to the left and right sides of the bottom of the fixed plate 3, U-shaped plates 7 are respectively fixedly connected to the left and right sides of the bottom of the fixed plate 3, baffles 8 are slidably connected to the rear sides of the two U-shaped plates 7, the rear ends of the two baffles 8 are respectively fixedly connected to the front ends of the corresponding telescopic rods 6, sealing grooves 9 are respectively opened on the front sides inside the two U-shaped plates 7, sealing plates 10 are respectively fixedly connected to the front ends of the two baffles 8, a base 11 is fixedly connected to the bottom of the reaction tower 1, a plurality of concentration monitors 12 are equidistantly fixedly connected to the top of the base 11, feeding ports 13 are respectively opened on the left and right sides of the reaction tower 1, an absorption mechanism 2 is arranged on the right side of the reaction tower 1, and the absorption mechanism 2 is used to absorb hydrogen fluoride;

[0033] Specifically, when using the hydrogen fluoride device, first put the two raw materials into the reaction tower 1 from the feeding ports 13 on the left and right sides respectively. In this way, the raw materials will respectively fall on the left and right sides of the reaction tower 1. Then the partition plate 5 will separate the raw materials. Next, the telescopic rods 6 will pull the baffles 8 backward, so that the raw materials slide from the upper grooves 4 to the lower base 11. When there is enough raw material, the telescopic rods 6 push the baffles 8 forward, so that the sealing plates 10 are inserted into the sealing grooves 9. The raw materials react on the base 11. At this time, use the concentration monitors 12 to observe the reaction situation. When one of the raw materials is used up, let the corresponding telescopic rod 6 pull backward to add the raw material.

[0034] Referring to Figure 2 and Figure 5, the absorption mechanism 2 includes an absorption box 201. The absorption box 201 is arranged on the right side of the reaction tower 1. A delivery pipe 202 is connected to the left side of the absorption box 201. The left end of the delivery pipe 202 is connected to the right side of the reaction tower 1. The same hollow pipe 203 is fixedly connected to both the left and right sides inside the absorption box 201. Nozzles 204 are fixedly connected to the bottom of the hollow pipe 203 at equal intervals. A liquid storage tank 205 is fixedly connected to the inner bottom of the absorption box 201. A water pump 206 is fixedly connected to the right side of the absorption box 201. One end of the water pump 206 is connected to an infusion pipe 207. One end of the infusion pipe 207 penetrates through the absorption box 201 and is connected to the hollow pipe 203;

[0035] Specifically, when hydrogen fluoride is generated, the hydrogen fluoride will enter the absorption box 201 along the delivery pipe 202. At this time, the water pump 206 starts to work, sucking out the absorption liquid in the liquid storage tank 205, transporting it through the infusion pipe 207 to the hollow pipe 203. As soon as the hydrogen fluoride enters the absorption box 201, the absorption liquid in the hollow pipe 203 will be sprayed out by the nozzles 204, mixing with the hydrogen fluoride and absorbing it.

[0036] Refer to Figure 1 and Figure 2 , snap fasteners 16 are fixedly connected to the outer periphery of the top of the reaction tower 1. A top cover 14 is arranged on the top of the reaction tower 1. Clamping grooves 15 are fixedly connected to the four sides of the top cover 14. One side of each of the multiple clamping grooves 15 is rotatably connected to a limit bolt 17. A fixed ring 18 is fixedly connected to the middle and lower part of the outer wall of the reaction tower 1. Multiple support feet 19 are fixedly connected to the four sides of the fixed ring 18. Rubber pads 20 are fixedly connected to the bottoms of the support feet 19. A sewage discharge pipe 21 is connected to the bottom of the base 11. One end of the sewage discharge pipe 21 is connected to a valve 22;

[0037] Specifically, the snap fasteners 16 and the clamping grooves 15 can fix the top cover 14 on the top of the reaction tower 1. The support feet 19 and the rubber pads 20 can make the reaction tower 1 more stable during operation. The sewage discharge pipe 21 can discharge the waste materials after the reaction in the tower, and the valve 22 can control whether the sewage discharge pipe 21 discharges sewage.

[0038] Refer to Figure 3 and Figure 4 , an observation port 23 is opened on the front side of the reaction tower 1. A transparent plate 24 is fixedly connected to the inside of the observation port 23. Chute grooves 25 are opened on both the left and right sides inside the two U-shaped plates 7. Sliders 26 are fixedly connected to both the left and right sides of the baffle 8. The multiple sliders 26 slide inside the corresponding chute grooves 25 respectively. A sealing ring 27 is fixedly connected to the bottom of the top cover 14. The outer wall of the sealing ring 27 fits with the inner wall of the reaction tower 1;

[0039] Specifically, the observation port 23 and the transparent plate 24 facilitate the observation of the operation inside the reaction tower 1. The chute 25 and the slider 26 enable the baffle 8 to move more stably within the U-shaped plate 7, and the sealing ring 27 enables the top cover 14 to better seal the reaction tower 1.

[0040] Working principle: When using the in-tower flow control device of the hydrogen fluoride device, it is necessary to first put the two reaction raw materials into the reaction tower 1 through the feed ports 13 on the left and right sides of the reaction tower 1 respectively. At this time, the two reaction raw materials are respectively placed on the left and right sides of the top of the fixed plate 3, so that the partition plate 5 divides the raw materials on the top of the fixed plate 3. At this time, make the telescopic rod 6 work to pull the baffle 8 backward, so that the raw materials move downward from the groove 4 to the base 11. At the same time, when the amount of raw materials poured is sufficient, the telescopic rod 6 pushes the baffle 8 forward, so that the sealing plate 10 is clamped into the sealing groove 9. At the same time, the raw materials react on the top of the base 11. At this time, the concentration monitor 12 monitors the items in the reaction. When one of the reaction raw materials is consumed, make the corresponding telescopic rod 6 work and move backward for discharging.

[0041] And when hydrogen fluoride is produced, at this time, the hydrogen fluoride will enter the inside of the absorption tank 201 through the delivery pipe 202. At the same time, make the water pump 206 work. At this time, the water pump 206 sucks out the absorption liquid in the liquid storage tank 205 and flows into the hollow pipe 203 through the infusion pipe 207. When the hydrogen fluoride enters the absorption tank 201, at this time, the nozzle 204 sprays the absorption liquid in the hollow pipe 203 to absorb the hydrogen fluoride, and the absorption liquid can also be recycled.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
