[0002] Bromide refers to a compound formed by bromine and other elements or groups. It can usually be obtained by the reaction of bromine gas with metals, non-metals or organic groups after the air inside the device is evacuated by inert gas, such as sodium bromide, potassium bromide and hydrogen bromide. In addition, depending on the specific type of bromide, it can be used as water disinfection, flame retardant, surfactant, etc. Therefore, bromide has a wide range of application value in the industrial and medical fields. However, due to the toxicity of bromine gas, safety regulations must be strictly observed when synthesizing bromide.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Please see attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 7 The embodiment of the present invention provides a high-efficiency bromide synthesis reaction device, comprising an outer tank body 1, A top cover 2 is arranged at the top of the outer tank body 1, an auxiliary mechanism 3 is arranged inside the outer tank body 1, a detection mechanism 4 is arranged inside the top cover 2, an air intake pipe 5 is fixedly connected to the front of the outer tank body 1, and the rear end of the air intake pipe 5 is arranged in front of the auxiliary mechanism 3; The auxiliary mechanism 3 includes a reaction tank 301, which is arranged inside the outer tank body 1. A servo motor 302 is fixedly connected to the bottom end of the reaction tank 301. The output end of the servo motor 302 passes through the reaction tank 301 and is fixedly connected to a transmission rod 303. An impeller 304 is fixedly connected to the lower outer side of the transmission rod 303. A perforated plate 305 is rotatably connected to the middle outer side of the transmission rod 303. A plurality of air guide tubes 306 are fixedly connected to the middle outer side of the reaction tank 301. The bottoms of the plurality of air guide tubes 306 are fixedly connected to the outer side of the bottom end of the reaction tank 301. Trapezoidal plates 1 307 are fixedly connected to the upper parts of both sides of the transmission rod 303. A plurality of trapezoidal plates 2 308 are slidably connected to the lower inner side of the reaction tank 301.

[0022] When the outer tank body 1 and the top cover 2 are closed, the required inert gas can be injected into the reaction tank 301 through the air inlet pipe 5, and the air inside the reaction tank 301 can be discharged by utilizing the characteristic that the density of the inert gas is greater than that of the air. Furthermore, bromine gas can also be injected into the reaction tank 301 through the air inlet pipe 5. Similarly, since the density of bromine gas is greater than the density of the inert gas used, after a certain amount of bromine gas is injected, the upper and lower parts of the reaction tank 301 can be inert gas and bromine gas respectively. At this time, the bromine gas can contact with the solid reactant placed in advance to produce a chemical reaction. At the same time, due to The reaction tank 301 can provide a fixation for the servo motor 302, so the servo motor 302 can drive the transmission rod 303 to rotate stably. Furthermore, the impeller 304 connected to the transmission rod 303 and the trapezoidal plate 307 can rotate synchronously. When the impeller 304 rotates, it can generate suction and suck the upper bromine gas to the bottom of the reaction tank 301 through the evenly distributed air guide pipe 306, and then pass through the orifice plate 305 to contact with the solid reactant, so as to achieve the purpose of improving the fluidity and diffusivity of the bromine gas and prevent the bromine gas from forming a concentration gradient on the surface of the solid reactant. The reaction rate is attenuated. In addition, when the trapezoidal plate 1 307 rotates with the transmission rod 303, it can push the solid reactants on the upper surface of the orifice plate 305 to move until the solid reactants contact the trapezoidal plate 2 308. Since the trapezoidal plate 2 308 has a certain weight, and both the trapezoidal plate 1 307 and the trapezoidal plate 2 308 have inclined surfaces with a certain slope, as the trapezoidal plate 1 307 continues to approach the trapezoidal plate 2 308, the solid reactants can pass over the trapezoidal plate 1 307 along the inclined surface of the trapezoidal plate 1 307, so as to promote the movement or overturning of the solid reactants. This can expose a new surface of the solid reactant to increase its contact area with the bromine gas. In summary, the reaction process can be accelerated and the reaction efficiency can be improved. In addition, when trapezoidal plate 1 307 moves to contact trapezoidal plate 2 308, trapezoidal plate 2 308 can move up along the reaction tank 301 under the push of trapezoidal plate 1 307 through their matching inclined surfaces. After trapezoidal plate 1 307 passes over the area where trapezoidal plate 2 308 is located, trapezoidal plate 2 308 can return to its initial position under the action of gravity, thereby preparing for a subsequent round of turning over of the solid reactant.

[0023] Please see attached Figure 2 -Attached Figure 4 The outer side of the orifice plate 305 is fixedly connected to the bottom of the reaction tank 301, the bottom ends of the trapezoidal plates 307 on both sides are slidably connected to the top of the orifice plate 305, the rear end of the air inlet pipe 5 is fixedly connected to the front end of the reaction tank 301, and the top of the reaction tank 301 abuts against the bottom end of the top cover 2.

[0024] The orifice plate 305 can be supported and fixed by the reaction tank 301, so as to prevent the orifice plate 305 from displacement or deflection. Furthermore, the orifice plate 305 can be used to limit the transmission rod 303, so as to prevent the transmission rod 303 from swinging when rotating and reducing its own structural life. The movement of the trapezoidal plate 1 307 along the orifice plate 305 can ensure that the trapezoidal plate 1 307 can effectively contact the orifice plate 305, thereby effectively promoting the movement of the solid reactant on the upper surface of the orifice plate 305. At the same time, the orifice plate 305 can also The movement trajectory of the trapezoidal plate 307 is limited to prevent the trapezoidal plate 307 from deflecting after being subjected to force, thereby increasing the force on the connection portion between it and the transmission rod 303. In addition, with the cooperation of the valve, the connection between the air inlet pipe 5 and the reaction tank 301 can ensure that the required inert gas and bromine gas can enter the reaction tank 301 in sequence, and the contact between the top of the reaction tank 301 and the top cover 2 can limit the internal space of the reaction tank 301, preventing the inert gas or bromine gas inside the reaction tank 301 from entering the area between the outer tank body 1 and the reaction tank 301.

[0025] Please see attached Figure 3 and attached Figure 7 The outer side of the bottom end of the reaction tank 301 is fixedly connected with an annular support seat 309, the bottom end of the annular support seat 309 is fixedly connected to the inner bottom end of the outer tank body 1, the bottom end of the impeller 304 is rotatably connected with a round table 310, the middle part of the round table 310 is rotatably connected to the outer side of the transmission rod 303, and the bottom end of the round table 310 is fixedly connected to the inner bottom end of the reaction tank 301.

[0026] The reaction tank 301 and the outer tank body 1 can be connected through the annular support seat 309, so that the reaction tank 301 can be effectively fixed and supported, preventing the reaction tank 301 from moving down and causing the servo motor 302 to be squeezed. At the same time, the grooves evenly distributed on the surface of the annular support seat 309 can accommodate each air duct 306 to ensure that the air duct 306 can function normally. Similarly, the round table 310 can be used to support the impeller 304, so that the impeller 304 moves more smoothly. In addition, the round table 310 can also increase the contact area between the transmission rod 303 and the reaction tank 301, further improving the stability of the transmission rod 303 during rotation.

[0027] Please see attached Figure 3 , Attachment Figure 4 , Attachment Figure 7 and attached Figure 8A cross-shaped slide groove 311 is provided in the upper part of the transmission rod 303, and a cross plate 312 is slidably connected inside the cross-shaped slide groove 311. A connecting block 313 is fixedly connected to the top of the cross plate 312, and a plurality of connecting rods 314 are fixedly connected to the outside of the connecting block 313. The bottoms of the plurality of connecting rods 314 are fixedly connected to H-shaped fixing frames 315, and the bottoms of the plurality of H-shaped fixing frames 315 are fixedly connected to trapezoidal push plates 316. The ends of the plurality of connecting rods 314 away from the connecting block 313 are rotatably connected to rollers 317. An annular guide frame 318 is fixedly connected to the middle part of the reaction tank 301, and the bottoms of the plurality of rollers 317 are slidably connected to the top of the annular guide frame 318.

[0028] The cross plate 312 corresponding to it can be accommodated by the cross-shaped slide groove 311, so that the cross plate 312 can be guided when it moves in the vertical direction along the transmission rod 303. At the same time, when the transmission rod 303 rotates, the cross plate 312 can be rotated synchronously by using the cross-shaped slide groove 311, and then the connecting block 313 connected to the cross plate 312 can make the evenly distributed connecting rods 314 drive each H-shaped fixing frame 315 and the trapezoidal push plate 316 to rotate accordingly. The rollers 317 are connected to each other, and the bottoms of the evenly distributed rollers 317 are in contact with the annular guide frame 318 fixed to the reaction tank 301. Therefore, when the transmission rod 303, the cross plate 312, the connecting block 313 and the connecting rod 314 drive the rollers 317 to move, each roller 317 can rotate horizontally around the transmission rod 303 and reciprocate vertically along the wavy contour on the upper surface of the annular guide frame 318. Conversely, the rollers 317 can reciprocate vertically along the wavy contour on the upper surface of the annular guide frame 318 through the connecting rod 314, the connecting block 313 and the cross plate 314. 2 can drive each H-shaped fixing frame 315 and the trapezoidal push plate 316 to move up and down accordingly. Among them, when the roller 317 moves to the bottom area of ​​the wavy contour on the surface of the annular guide frame 318, the trapezoidal push plate 316 can contact the solid reactants accumulated on the upper surface of the orifice plate 305, and then can apply a thrust to the locally accumulated solid reactants before the roller 317 moves up, so as to disperse the accumulated solid reactants, prevent the accumulated metallic sodium from reacting with bromine gas and releasing a large amount of heat in a short time, and then avoid its temperature change beyond the normal temperature control capability range to cause the internal air pressure of the reaction tank 301 to rise rapidly, further prevent the reaction tank 301 from being deformed and damaged due to excessive internal air pressure, achieve the purpose of protecting the reaction tank 301, and reduce potential safety hazards. In addition, when the local temperature rises, it can further aggravate the reaction process and form a vicious circle. Therefore, multiple trapezoidal push plates 316 are required to timely push the solid reactants that may be accumulated on the surface of the orifice plate 305 to reduce the risk level.

[0029] Please see attached Figure 2 and attached Figure 4A counterweight block 319 is fixedly connected to the top of the connecting block 313 , and a plurality of rollers 317 are slidably connected to the inside of the reaction tank 301 at one end away from the connecting rod 314 .

[0030] The counterweight block 319 can effectively increase the downward force of the trapezoidal push plate 316, thereby preventing the trapezoidal push plate 316, H-shaped fixing frame 315, connecting rod 314 and connecting block 313 from being forced to move upward due to their small weight when the trapezoidal push plate 316 contacts the solid reactant, thereby preventing the trapezoidal push plate 316 from being unable to effectively flatten the accumulated solid reactant. In addition, since the roller 317 contacts the inner wall of the reaction tank 301 away from the side of the connecting rod 314, the rollers 317 can be restricted by each other through the connecting rod 314 and the connecting block 313, so that each roller 317 can always be on the upper surface of the annular guide frame 318, thereby preventing a roller 317 from detaching from the annular guide frame 318 and interfering with the normal movement of the connecting rod 314, the trapezoidal push plate 316, the cross plate 312 or other rollers 317.

[0031] Please see attached Figure 2 , Attachment Figure 5 , Attachment Figure 6 and attached Fig. 9 The detection mechanism 4 includes a fixing ring 401, the outer side of the fixing ring 401 is fixedly connected to the inside of the top cover 2, the inside of the fixing ring 401 is fixedly connected to a cooling bin 402, the bottom of the cooling bin 402 is fixedly connected to a connecting tube 403, the upper part of the outer side of the connecting tube 403 is fixedly connected to a spiral tube 404, the upper part of the connecting tube 403 is provided with a through port 1 405, the connecting tube 403 is connected to the spiral tube 404 through the through port 1 405, the side of the spiral tube 404 away from the connecting tube 403 is fixedly connected to a vertical tube 406, the top of the vertical tube 406 passes through the cooling bin 402 and is fixedly connected to a hollow tube 1 409, the outer side of the vertical tube 406 is fixedly connected to a liquid storage tank 407, the hollow tube 1 409 is located inside the liquid storage tank 407, and a plurality of through ports 2 408 are provided on the top of the vertical tube 406.

[0032] The top cover 2 can provide support for the fixing ring 401, and the fixing ring 401 can make the cooling chamber 402 stable and not shaken. Before the inert gas is injected, a certain amount of liquid substances such as water, benzene, cyclohexane or ethanol that do not react significantly with bromine gas at room temperature is injected into the liquid storage tank 407 until the liquid level is above the bottom of the hollow cylinder 409 and below the port 408. During the reaction, when the heated inert gas or bromine gas enters the spiral tube 404 through the port 405 on the surface of the connecting cylinder 403, the cooling chamber 402 is used to cool the inert gas or bromine gas. The water inside 402 can cool the inert gas or bromine gas when it moves along the spiral tube 404. Since the boiling point of bromine gas is 58.8 degrees Celsius, when the heat carried by the bromine gas is continuously absorbed by the water inside the cooling chamber 402 and the temperature is lower than 58.8 degrees Celsius, the bromine gas can be converted from gas to liquid. In addition, the spiral tube 404 has a certain height difference, and the middle area is the lowest. Therefore, after the bromine gas is liquefied, it can move to the middle of the spiral tube 404 and return to the connecting tube 403 through the port 1 405 to reduce its active If the bromine gas passes through the spiral tube 404 and is not completely liquefied, the bromine gas can leave the cooling chamber 402 through the vertical tube 406, and then enter the hollow cylinder 1 409 through the evenly distributed opening 2 408 at the top of the vertical tube 406. Since there are liquid substances such as water, benzene, cyclohexane or ethanol in the liquid storage tank 407 that are not easy to react with the bromine gas at room temperature, the bromine gas can move down along the hollow cylinder 1 409 under the push of the subsequent gas and gradually enter the liquid substance, and then form bubbles and move down to the air. The area blocked by the hollow cylinder 409 can be left only after reaching the bottom of the core cylinder 409. Then, by observing with an external camera whether there are bubbles floating along the area between the liquid storage tank 407 and the hollow cylinder 409, it can be determined whether there is a gas leakage, so as to avoid the failure to detect the leakage of bromine gas in a large area in time, thereby improving the safety of the reaction process and preventing nearby workers from inhaling bromine gas and affecting their health. In addition, bromine gas will also react with liquid substances to a certain extent to consume the leaked volume, avoiding excessive diffusion of bromine gas into the air.

[0033] Please see attached Figure 6 and attached Fig. 9 The bottom end of the spiral tube 404 is fixedly connected to a plurality of fixing plates 410 , the bottom ends of the plurality of fixing plates 410 are all fixedly connected to the bottom end of the cooling bin 402 , and the bottom end of the liquid storage tank 407 is fixedly connected to one side of the rear portion of the top end of the cooling bin 402 .

[0034] By means of a plurality of fixing plates 410, the spiral tube 404 can be located in the central area inside the cooling bin 402, so that more water can fully contact the spiral tube 404 and absorb the heat carried by the gas inside it through the spiral tube 404. At the same time, there are holes and plugs on the rear side of the top of the cooling bin 402 for replacing the water inside the cooling bin 402. In addition, the cooling bin 402 can further support the liquid storage tank 407 to disperse the force acting on the connection area between the liquid storage tank 407 and the vertical pipe 406.

[0035] Please see attached Figure 2 , Attachment Figure 5 and attached Fig. 9 A storage barrel 411 is fixedly connected to the middle of the top of the cooling bin 402, the top of the storage barrel 411 is fixedly connected to the top of the top cover 2, a return liquid pipe 412 is fixedly connected to the upper outer side of the storage barrel 411, the bottom of the return liquid pipe 412 is arranged inside the liquid storage tank 407, and a liquid inlet pipe 413 is fixedly connected to the lower outer side of the storage barrel 411, and the end of the liquid inlet pipe 413 away from the storage barrel 411 is fixedly connected to the outside of the liquid storage tank 407.

[0036] The material storage barrel 411 can cooperate with the top cover 2 and the cooling chamber 402 to form a relatively closed space, and then the pump body injects liquid substances such as water, benzene, cyclohexane or ethanol that do not react significantly with bromine gas at room temperature into the closed space until the liquid level approaches the upper area of ​​the return liquid pipe 412 and then stops injecting. When the reaction is in progress, the electric control valve controlling the liquid inlet pipe 413 is opened to connect the material storage barrel 411 with the liquid storage tank 407. At this time, the liquid substance in the material storage barrel 411 can pass through the liquid inlet pipe 413 under the action of gravity. Entering the liquid storage tank 407, as the liquid substance is discharged, a vacuum area may be formed inside the storage barrel 411, thereby generating suction. At this time, through the return pipe 412 in contact with the liquid substance in the liquid storage tank 407, part of the liquid substance in the liquid storage tank 407 may be sucked back into the storage barrel 411 while the liquid substance in the storage barrel 411 is discharged, thereby realizing the circulation of the liquid substance, so as to enable the liquid substance to more fully contact with the bromine gas that may leak, thereby enhancing its ability to consume the leaked bromine gas.

[0037] Please see attached Figure 2 and attached Figure 6 The bottom end of the connecting tube 403 is fixedly connected with a heat insulation plate 414, an air inlet 415 is opened in the middle of the heat insulation plate 414, the bottom end of the heat insulation plate 414 is fixedly connected with a hollow tube 416, the bottom end of the hollow tube 416 is fixedly connected with an air bag 417, the top of the air bag 417 is fixedly connected with an annular baffle 418, and the top of the hollow tube 416 is opened with a plurality of through holes 419.

[0038] Most of the heat inside the reaction tank 301 can be isolated under the top cover 2 by the heat insulation plate 414 to prevent the heat from directly contacting the cooling chamber 402 and affecting the treatment effect of the cooling chamber 402 on the spiral tube 404. In addition, the hollow cylinder 416 can accommodate the air bag 417 with light gas inside. When the bromine gas reacts with the solid reactant, the heat generated or the additional heat applied can be transferred to the air bag 417 through the small holes at the bottom of the hollow cylinder 416, so that the air bag 417 can be quickly heated and expanded, and the annular baffle 418 can be moved up to evenly distribute the gas through the air bag 417. Port three 419 is blocked to prevent bromine gas or inert gas from directly entering hollow cylinder two 416, spiral tube 404 and vertical tube 406 due to factors such as heat, air pressure and gas flow during the reaction, thereby avoiding a large loss of heat or direct discharge of bromine gas. In addition, before the airbag 417 expands, with the injection of bromine gas, part of the inert gas can enter hollow cylinder two 416 through the evenly distributed port three 419, and then enter the connecting cylinder 403, spiral tube 404 and vertical tube 406 along the air inlet hole 415 and be discharged to the outside, so as to complete the normal discharge of the inert gas.

[0039] Please see attached Figure 5 and attached Figure 6 The outer side of the heat insulation plate 414 is fixedly connected to the bottom of the top cover 2, the outer side of the top of the heat insulation plate 414 is fixedly connected to the annular support seat 420, the top of the annular support seat 420 is fixedly connected to the outer side of the bottom end of the cooling chamber 402, and the outer side of the annular baffle 418 is slidably connected to the inside of the hollow cylinder 416, and the hollow cylinder 416 is opposite to the air inlet 415.

[0040] The heat insulation plate 414 can be fixed by the top cover 2, and the contact area between the heat insulation plate 414 and the cooling bin 402 can be enhanced by the annular support seat 420, which can further improve the stability of the heat insulation plate 414 and the cooling bin 402. The hollow cylinder 416 can be used to prevent the annular baffle 418 from shaking when it moves, thereby ensuring the shielding effect of the annular baffle 418 on the opening 419 and the air inlet 415. In addition, the hollow cylinder 416 is opposite to the air inlet 415, so that the annular baffle 418 will not be unable to block the gas from entering the connecting cylinder 403 through the air inlet 415 due to misalignment.

[0041] Working principle: When in use, place the sheet or block solid reactant on the surface of the orifice plate 305, then close and lock the top cover 2, so that the outer tank body 1 and the reaction tank 301 can effectively contact the top cover 2, and then inject inert gas such as argon and argon into the reaction tank 301 through the air inlet pipe 5. Since the density of the injected inert gas is greater than the density of the air inside the reaction tank 301, the inert gas can be used to make the air inside the reaction tank 301 gradually enter the hollow cylinder 2 416 and the connecting cylinder 403 through the evenly distributed port 3 419, and then be discharged to the outside through the spiral tube 404 and the vertical tube 406. When the reaction tank 301 is filled with inert gas, stop injecting inert gas and inject bromine into the reaction tank 301 again through the air inlet pipe 5. Similarly, by utilizing the characteristic that the density of bromine gas is greater than the density of the inert gas used, the bromine gas can gradually exceed the air inlet at the upper part of the air guide tube 306 from bottom to top. When the top layer of bromine gas is in the area between the air guide tube 306 and the second hollow cylinder 416, the injection of bromine gas is stopped, and then the internal temperature of the reaction tank 301 is controlled according to the specific reaction requirements. As the temperature rises, the light gas inside the air bag 417 can expand rapidly and push the annular baffle 418 to move up along the second hollow cylinder 416 until the annular baffle 418 blocks the evenly distributed through-ports 419 and cooperates with the heat insulation board 414 to prevent the bromine gas or the inert gas from continuing to freely enter the internal space of the top cover 2, thereby starting the servo motor 302, so that the transmission rod 303 can drive the impeller 304 to rotate. The upper bromine gas is sucked to the bottom of the reaction tank 301 through the evenly distributed air guide pipe 306 by the impeller 304, and then the bromine gas can be pushed by the subsequent bromine gas to continuously pass through the orifice plate 305 and contact the solid reactant to prevent the formation of a concentration gradient on the surface of the solid reactant and affect the reaction process. At the same time, when the transmission rod 303 rotates, the solid reactant on the upper surface of the orifice plate 305 can be pushed to move through the trapezoidal plate 1 307. When the trapezoidal plate 1 307 and the solid reactant approach and contact the trapezoidal plate 2 308, the solid reactant can move along the inclined surface of the trapezoidal plate 1 307 and pass over the trapezoidal plate 1 307 under the extrusion of the trapezoidal plate 1 307 and the trapezoidal plate 2 308. At this time, the solid reactant can make its sides in the process of turning and moving. The connecting block 313 is in effective contact with the bromine gas, thereby increasing the contact area and improving the reaction speed. At the same time, since the connecting block 313 is in contact with the transmission rod 303 through the cross plate 312 and the cross-shaped slide groove 311, the connecting block 313 can also move vertically along the transmission rod 303 while rotating with the transmission rod 303. Under the cooperation of the counterweight block 319, the evenly distributed rollers 317 can always contact the wavy contour on the upper surface of the counterweight block 319. When the transmission rod 303 drives the cross plate 312, the connecting block 313 and the connecting rod 314 to rotate, the rollers 317 can rotate accordingly and move vertically along the annular guide frame 318. Conversely, the H-shaped fixing frame 315 can drive the trapezoidal push plate 316 to move synchronously through the connecting rod 314.When the trapezoidal push plate 316 is in a lower position, it can push flat the solid reactants on the surface of the orifice plate 305 to prevent possible accumulation, thereby preventing the accumulation from causing excessive temperature in the local area due to concentrated reaction, further preventing abnormal temperature control due to accelerated heat release caused by accelerated reaction, and avoiding excessive air pressure inside the reaction tank 301 due to rapid temperature increase in a short period of time, thereby achieving the purpose of protecting the reaction tank 301 and reducing its deformation probability. When the trapezoidal push plate 316 is in a higher position, it can be misaligned with the trapezoidal plate 2 308 to prevent collision with each other. In addition, under the influence of various factors such as temperature, air pressure, and the actual injection amount of bromine gas, if there is still bromine gas or inert gas passing through the obstruction of the annular baffle 418 and entering the connecting tube 403 and the spiral tube 404 through the port 3 419 and the air inlet 415, the water inside the cooling chamber 402 can absorb heat from the bromine gas or inert gas when it moves along the spiral tube 404, thereby causing it to quickly When the temperature of bromine gas is lower than 58.8 degrees Celsius, it can be converted into liquid state to prevent it from continuing to diffuse outward from the vertical pipe 406. For the bromine gas that has not been converted into liquid state after being cooled by the cooling chamber 402, it can be allowed to enter the interior of the hollow cylinder 1 409 from the vertical pipe 406 through the second port 408. Further, under the push of the subsequent bromine gas or inert gas, it can enter the liquid substance that can react with the bromine gas to a certain extent in the liquid storage tank 407 along the hollow cylinder 1 409. At this time, the use of liquid substance can consume part of the bromine gas to a certain extent, and while reducing the amount of bromine gas leakage, the remaining bromine gas can pass through the bottom of the hollow cylinder 1 409 in the form of bubbles and then float up from the outside of the hollow cylinder 1 409. Then, the camera can promptly detect whether there are bubbles, so as to prevent the bromine gas from leaking for a long time and over a large area without being discovered, and then prevent the nearby workers from being forced to inhale the bromine gas and affecting their own health after a large amount of bromine gas leakage, thereby improving the safety during production.
