Description

TECHNICAL FIELD

[0001] The present application belongs to the field of chemical substance storage, and relates to a bromine storage technology, in particular to a novel bromine storage device. BACKGROUND

[0002] Bromine (Br2) is a highly corrosive and toxic chemical substance widely used in industry and laboratories. Bromine is a liquid at room temperature and pressure, with a strong irritating odor, and can volatilize to form a red-brown toxic gas at room temperature, which poses a serious threat to human health. This makes the storage and handling of bromine challenging, especially in preventing bromine leakage and volatile gas emission. Therefore, it is crucial to ensure that bromine and its solutions (such as bromine water) do not release harmful gases during storage and handling.

[0003] During the storage of bromine and bromine water, although sealed containers are usually used to reduce the leakage of volatilized gas, due to the strong volatility of bromine, this sealing method often fails to completely prevent the emission of bromine. In order to overcome the problem of unreliable sealing of the sealed container, the current practice is to place the sealed container storing bromine in a well-ventilated place, and to additionally seal the sealed container with wax and water, such as:

[0004] (1) Use a container, half of the space of the container stores bromine, and the remaining space is filled with pure water. There is no other isolation material between the bromine at the bottom of the container and the water. When the water solution is saturated with bromine, it is basically insoluble. This water sealing method is simple, convenient and low in cost. Although it can reduce the diffusion of bromine volatilization into the air to some extent, when the container is opened for use of bromine, it is no longer possible to store the remaining bromine in the container in the same water sealing manner. In addition, the plastic bottle cap and wax seal cannot completely prevent bromine gas from leaking out.

[0005] (2) Use a double-layer container, place the sealed container containing bromine into another larger external container, pour a certain amount of water into the external container, and make the water level higher than the bottle opening of the internal sealed container. Compared with a single container, this sealing method can reduce the diffusion of bromine volatilization into the air to a higher degree, but once the water solution in the external container is saturated with leaked bromine, it will lose the function of preventing bromine from leaking out, and the sealing period is short, which is not suitable for long-term sealed storage.

[0006] In summary, during the storage of bromine and bromine water, although sealed containers are commonly used to reduce the leakage of volatile gases, due to the strong volatility of bromine, traditional sealing methods are often unable to completely prevent the emission of bromine. This not only causes laboratories or industrial sites to be filled with unpleasant odors, but may also pose a serious threat to personnel health and equipment safety. Therefore, it is urgent to propose a new type of bromine storage device that can more effectively compensate for the shortcomings of sealed containers and solve the problem of unreliable sealing of bromine wax seals and water seals. Summary of the Invention

[0007] The object of the present invention is to provide a novel bromine storage device to solve the problem of unreliable sealing of bromine wax seals and water seals.

[0008] To achieve the above object, the present invention provides the following solutions:

[0009] The present invention provides a bromine storage device, comprising a first container, a second container and an air guide channel, wherein:

[0010] The first container is provided with a bromine bottle receiving chamber, in which the bromine bottle can be placed; the cavity wall of the first container is provided with an air guide hole communicating with the bromine bottle receiving chamber;

[0011] The second container is provided with a neutralizing liquid receiving chamber, and the neutralizing liquid receiving chamber is used to hold the neutralizing liquid; the cavity wall of the second container is provided with a through hole communicating with the neutralizing liquid receiving chamber;

[0012] The air inlet end of the air guide channel is sealed and connected to the air guide hole, and the air outlet end of the air guide channel extends into the neutralization liquid holding chamber through the through hole and is immersed below the liquid level of the neutralization liquid. The air guide channel can directionally guide the bromine gas leaked from the bromine bottle into the neutralization liquid to neutralize the bromine gas through the neutralization liquid.

[0013] In one embodiment, the air inlet end of the air guide channel is fixedly connected to the air guide hole, and the first container is arranged on one side of the second container, or the first container is assembled above the second container through a supporting structure.

[0014] In one embodiment, the air guide hole is located on the bottom cavity wall of the first container, the through hole is located on the top cavity wall of the second container, the first container is assembled above the second container through the supporting structure, and the air outlet end of the air guide channel extends downward into the neutralization liquid holding cavity.

[0015] In one embodiment, the support structure is a bracket structure that is separated from the second container, and the first container is arranged on the bracket structure and is erected above the second container through the bracket structure.

[0016] In one embodiment, the supporting structure is a top wall of the second container, and the first container is directly disposed on the top wall of the second container;

[0017] Alternatively, the support structure is a support step provided on the inner edge of the through hole, the bottom of the first container is adapted to the support step, and the support step can be embedded with the bottom of the first container and support the first container.

[0018] In one embodiment, the air guide hole is arranged on one side of the bottom cavity wall of the first container, and the other side of the bottom cavity wall of the first container serves as a bromine bottle placement area, and the bromine bottle placement area is provided with a placement groove adapted for the bromine bottle.

[0019] In one embodiment, the bromine bottle placement area is provided with a plurality of placement grooves, the placement grooves are arranged in a one-to-one correspondence with the bromine bottles, and the sizes and specifications of all the placement grooves are not completely the same or are completely different.

[0020] In one embodiment, the neutralization liquid holding chamber is provided with a liquid level detection device, and the liquid level detection device is used to detect the liquid level height of the neutralization liquid in the neutralization liquid holding chamber.

[0021] In one embodiment, at least one of the first container and the second container is provided with a handle.

[0024] The bromine storage device provided by the present invention has a novel and reasonable structure. It adopts a dual-container structure of a first container and a second container, wherein the first container is used to store the bromine bottle, and the second container is used to hold the neutralizing liquid for neutralizing the leaked bromine gas. Then, an air guide channel is used to specifically connect the first and second containers. The design is ingenious. The air guide channel is connected to the first container, effectively limiting the diffusion path of the bromine gas, so that the leaked bromine gas can only be discharged through a single outlet, namely the air guide channel, and enter the neutralizing liquid in the second container, where it undergoes a neutralization reaction. The combined structure of the air guide channel and the first container is equivalent to setting a physical barrier for the leaked bromine gas, which can effectively limit the volatilization and diffusion of bromine. Combined with the subsequent neutralization effect of the neutralizing liquid, the leakage of bromine gas into the air can be completely prevented. Even for unsealed bromine bottles, more efficient gas sealing can be achieved through this design, solving the problem that the bottle mouth of the unsealed bromine bottle cannot be effectively resealed and is prone to leakage. The device is suitable for storing bromine bottles that have been opened or are still sealed.

[0025] If a bromine bottle leaks, the design of this invention allows the leaked bromine to directly contact the neutralizing solution and react quickly. This automated treatment system, which requires no mechanical devices, significantly improves the safety of bromine storage devices and prevents serious leaks even when unsupervised.

[0026] The design of the present invention allows the majority of leaked bromine to be absorbed and processed by the neutralizing solution, significantly reducing bromine pollution to the air and environment, thus complying with environmental protection requirements. Furthermore, the present invention lacks any mechanical components. The material selection and structural design ensure the durability of the container device, reducing the need for regular equipment maintenance or replacement of mechanical consumables, thereby lowering long-term operating costs.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0040] The object of the present invention is to provide a novel bromine storage device to solve the problem of unreliable sealing of bromine wax seals and water seals.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] This embodiment provides a bromine storage device 100, comprising a first container 1, a second container 2, and an air guide channel 3. A bromine bottle receiving chamber 11 is provided in the first container 1. A bromine bottle 12 can be placed in the bromine bottle receiving chamber 11. The bromine bottle 12 is a finished product that often uses a bottle body and a bottle cap to seal and store liquid bromine. However, bromine gas leakage may still occur at the connection between the bottle cap and the bottle body. The cavity wall of the first container 1 is provided with an air guide hole 13 that communicates with the bromine bottle receiving chamber 11. Except for the location of the air guide hole 13, the entire bromine bottle receiving chamber 11 is a closed structure. The second container 2 is provided with a neutralizing liquid receiving chamber 21 for holding a neutralizing liquid 22. The cavity wall of the second container 2 is provided with a through hole 23 that communicates with the neutralizing liquid receiving chamber 21. The through hole 23 is often located above the liquid level of the neutralizing liquid 22 to prevent the neutralizing liquid 22 from overflowing. The first container 1 and the second container 2 need to be used in conjunction with each other. During use, the air inlet end of the air guide channel 3 is in sealed communication with the air guide hole 13. The air outlet end of the air guide channel 3 extends through the through hole 23 into the neutralizing liquid holding chamber 21 and is immersed a distance below the liquid level of the neutralizing liquid 22. The air guide channel 3 can directionally guide the bromine gas leaking from the bromine bottle 12 into the neutralizing liquid 22, thereby neutralizing the bromine gas. The neutralizing liquid 22 is a finished chemical solution. The neutralization reaction process and principle of the neutralization reaction with bromine gas (bromine) are well known in the art and will not be repeated here.

[0044] In the above-mentioned bromine storage device 100, the first container 1 and the second container 2 are designed independently of each other. The first container 1 is used to store the bromine bottle 12, and the second container 2 is used to hold the neutralizing liquid 22 for neutralizing the leaked bromine gas; the air guide channel 3 is connected to the first container 1, effectively limiting the diffusion path of the bromine gas, so that the leaked bromine gas can only be discharged through the only outlet, namely the air guide channel 3, and enter the neutralizing liquid to react with the neutralizing liquid. The combined structure of the air guide channel 3 and the first container 1 is equivalent to setting a physical barrier for the leaked bromine gas, which can effectively limit the volatilization and diffusion of bromine. Combined with the neutralizing effect of the neutralizing liquid 22, the leakage of bromine gas can be completely eliminated.

[0045] In one embodiment, in order to simplify the structure and reduce the number of parts of the overall device, one of the first container 1 and the second container 2 can be connected to the air guide channel 3 and assembled into an integral part. As a preferred solution, Figure 2 、 Figures 4-6 As shown, the air inlet end of the air guide channel 3 is fixedly connected to the air guide hole 13, and the air guide channel 3 is located outside the first container 1; the first container 1 is arranged on one side of the second container 2, or the first container 1 is assembled above the second container 2 through a supporting structure. The specific shape of the air guide channel 3 can be adaptively designed according to the positional relationship between the first container 1 and the second container 2. The optional pipeline forms of the air guide channel 3 include straight pipe channels, curved pipe channels, etc.

[0046] In one embodiment, the first container 1 is preferably assembled above the second container 2 through a supporting structure, and the air guide hole 13 is opened on the bottom cavity wall of the first container 1, the through hole 23 is opened on the top cavity wall of the second container 2, the air guide channel 3 is connected directly below the air guide hole 13, and the air outlet end of the air guide channel 3 extends downward into the neutralization liquid holding chamber 21.

[0047] In one embodiment, Figure 2 、 Figures 4-6 As shown, the air-guiding channel 3 is preferably a straight tube, which can specifically be a cylindrical straight tube or a prismatic straight tube (such as a quadrangular prism with a rectangular cross-section, a pentagonal prism with a regular pentagonal cross-section, etc.). The first container 1 is a closed container. The air-guiding channel 3 is similar to a chimney, connected to the bottom of the first container 1 and opening downward. The air-guiding channel 3 is the only outlet of the first container 1 and also serves as a window for accessing and placing the bromine bottle 12. The apertures of the air-guiding channel 3 and the air-guiding hole 13 are of moderate size, allowing the bromine bottle 12 to be conveniently placed in a suitable location within the first container 1 for storage or removed from the first container 1 through these openings.

[0048] In one embodiment, the air-guiding channel 3 and the first container 1 can be assembled and connected by screw threading, interference fit, or can be integrally formed. As a preferred embodiment, the air-guiding channel 3 and the first container 1 can be integrally formed to prevent leakage at the interface between the air-guiding channel 3 and the first container 1.

[0049] In one embodiment, Figures 3-7 As shown, the second container 2 is preferably an open-top container, and its top opening is a through hole 23. Accordingly, the aforementioned support structure is preferably a support step 24 provided on the inner edge of the through hole 23. The bottom of the first container 1 is adapted to the support step 24, and the support step 24 can be embedded with the bottom of the first container 1 and support the first container 1. With this structure, the second container 2 effectively supports the first container 1 by its own structure. The first container 1 and the second container 2 can be assembled and combined in a simple plug-in manner to form a double-layer container. Based on this design, after the bromine bottle 12 is taken or placed in the air guide channel 3, there is no need to use a special sealing device or additional treatment for the air guide channel 3. By utilizing the gravity of the first container 1, the air outlet end of the air guide channel 3 can be immersed in the neutralizing liquid after being simply and effectively connected to the second container 2, thereby achieving a water seal. The first container 1 and the second container 2 are also very convenient to separate. The first container 1 can be directly removed from the second container 2.

[0050] In one embodiment, Figure 2 、 Figure 4 and Figure 5 As shown, air guide holes 13 are provided on one side of the bottom wall of the first container 1 (the left side in the figure). The other side of the bottom wall of the first container 1 (the right side in the figure) serves as a bromine bottle placement area 14. Bromine bottle placement area 14 is provided with a placement groove 15 adapted for bromine bottle 12. Bromine bottle 12 is placed in placement groove 15 to prevent it from sliding, misalignment, or even tipping over, thereby improving the reliability, stability, and safety of bromine bottle 12 storage and reducing risks when moving the container.

[0051] In one embodiment, Figures 2-6 As shown, the bromine bottle placement area 14 is preferably provided with a plurality of placement grooves 15, and the placement grooves 15 are arranged in a one-to-one correspondence with the bromine bottles 12 (ie, each placement groove 15 generally only places one bromine bottle 12).

[0052] In an embodiment, the sizes of all the placing grooves 15 can be completely the same, but in order to store bromine bottles 12 of different sizes, the sizes of all the placing grooves 15 can also be set to be not completely the same or completely different, and the placing grooves 15 can be customized according to the sizes of the bromine bottles 12. The size of the placing groove 15 generally refers to the groove width, for example, the placing groove 1 is a cylindrical groove, and the groove width is the cross-sectional diameter of the cylindrical groove; the groove depths of all the placing grooves 15 can be the same, and the groove depth of the placing groove 15 is mainly to be able to safely place the bromine bottle 12. For example, two bromine bottles 12 of different sizes are prepared to be placed, the diameters of the bottoms of the bromine bottles 12 are 8.5 cm and 12.5 cm respectively, and the heights are both 10 cm. When the wall thickness of the first container 1 is 1 cm, the outer diameter of the placing groove 15 matched with the bromine bottle 12 with a diameter of 8.5 cm can be 11 cm, and the inner diameter can be 9 cm, and the outer diameter of the placing groove 15 matched with the bromine bottle 12 with a diameter of 12.5 cm can be 15 cm, and the inner diameter can be 13 cm; the groove depths of the two placing grooves 15 can both be set to 5 cm.

[0053] In an embodiment, as shown in FIG. 1, Figures 3-6 The placing groove 15 adopts a cylindrical groove, all the placing grooves 15 are arranged on the bottom cavity wall of the first container 1, and the groove bottoms of all the placing grooves 15 protrude the lower surface of the bottom cavity wall of the first container 1. As a preferred solution, the placing groove 15 is integrally formed on the bottom cavity wall of the first container 1. Figure 2 The arrangement of the five placing grooves 15 is shown in FIG. 1. In actual application, the number and arrangement of the placing grooves 15 on the bottom cavity wall of the first container 1 can be flexibly adjusted as needed. The groove size of the first container 1 includes the depth, which needs to be considered to be able to appropriately and safely place the bromine bottle.

[0054] In an embodiment, considering that the liquid level of the neutralizing liquid 22 in the second container 2 can gradually decrease during use, the embodiment preferably configures a liquid level detection device in the neutralizing liquid containing cavity 21. The liquid level detection device is used to detect the liquid level height of the neutralizing liquid 22 in the neutralizing liquid containing cavity 21, and once the liquid level of the neutralizing liquid 22 is lower than the required height, the neutralizing liquid 22 can be supplemented in time to maintain the effective function. The above-mentioned liquid level detection device can select a liquid level sensor. The liquid level sensor is a finished product, and the specific structure and working principle are not described here.

[0055] In one embodiment, at least one of the first container 1 and the second container 2 is provided with a handle 16 to facilitate the taking and transferring of the first container 1 and the second container 2. As a preferred solution, the handle 16 can be arranged only on the first container 1, and the handle 16 is symmetrically arranged on the top of the left and right sides of the first container 1. The handle 16 can be assembled and connected with the first container 1 by means of bolt connection or the like, or can be integrally formed with the first container 1, as shown in Figure 2 The handle 16 is integrally formed with the first container 1, and the integrally formed structure has higher strength, which is conducive to prolonging the service life of the handle 16 and the first container 1.

[0056] In one embodiment, at least one of the first container 1 and the second container 2 is a prismatic container or a cylindrical container. The outer contour shapes of the first container 1 and the second container 2 can be the same or different, and as a preferred solution, as shown in Figures 1-3 The first container 1 and the second container 2 of the embodiment are both prismatic containers, for example, both are quadrangular prisms. Considering that the first container 1 needs to be inserted and assembled with the support step 24 on the top of the second container 2, the bottom area of the first container 1 is smaller than the top area of the second container 2. After the first container 1 is placed on the support step 24, the first container 1 and the support step 24 are gap-fitted, and the first container 1 can cover the entire through hole 23, as shown in Figure 1 , Figure 4 and Figure 5 .

[0057] In one embodiment, the first container 1 can be removed to add the neutralizing liquid 22 into the second container 2 through the through hole 23; correspondingly, in order to facilitate the discharge of the waste liquid after the neutralization reaction in the second container 2, a discharge port 25 can be arranged at the bottom of the side wall of the second container 2, and the discharge port 25 is generally provided with a piston or a valve to control the opening and closing of the discharge port 25.

[0058] The working principle and use process of the bromine storage device 100 are as follows:

[0059] The first container 1 is a closed container, and the gas guide channel 3 is connected below the first container 1 and has a downward opening. The second container 2 is an open container, and the through hole 23 on the top of the second container 2 is used to hold the neutralizing liquid 22. The opening size of the support step 24 at the through hole 23 of the second container 2 matches the size of the bottom of the first container 1, so that the two parts can be connected and assembled.

[0060] The use process is as follows:

[0061] (1) First, add an appropriate amount of neutralizing liquid 22 that can neutralize bromine into the second container 2.

[0062] (2) Next, ensure that the opening of the air channel 3 on the first container 1 is facing downward, and place the bromine bottle 12 through the air channel 3 into the corresponding placement groove 15 in the bromine bottle receiving chamber 11. There are two protruding handles 16 on each side of the top of the first container 1 to facilitate the operator to move or fix the first container 1.

[0063] (3) Then, the bottom of the first container 1 is connected to the support step 24 of the second container 2 by plugging. While the support step 24 supports the first container 1, the bottom of the gas guide channel 3 is completely immersed in the neutralizing liquid 22. The bottom of the first container 1 and the support step 24 of the second container 2 can form a clearance fit through appropriately designed dimensions, allowing the first container 1 to utilize the principle of gravity, that is, to be tightly connected to the second container 2. However, this connection does not require absolute sealing and complete airtightness. After the bottom of the first container 1 is pressed onto the support step 24 of the second container 2, the contact position between the two can still allow gas to pass through.

[0064] If the bromine bottle 12 leaks, the leaked bromine can only be discharged through the only outlet on the first container 1, namely the air guide channel 3. Since the bottom air outlet end of the air guide channel 3 is completely immersed in the neutralizing liquid 22, the leaked bromine will react with the neutralizing liquid 22 to neutralize it. If the product generated by the neutralization reaction is solid, it will be deposited under the neutralizing liquid 22, or further exist in the form of a solution dissolved in water. If the product is a gas (such as carbon dioxide), it can be released into the air to generate positive pressure and naturally discharged through the seam between the first container 1 and the second container 2.

[0065] When the entire bromine storage device 100 is in use, the place where the device is placed still needs to be managed safely and ensured to be well ventilated.

[0066] It should be noted that the materials of the first container 1 and the second container 2 must be compatible with the neutralizing liquid 22 used to prevent the containers from being corroded.

[0067] The above embodiment will be described in detail below with reference to several specific examples.

[0068] Example 1: Using a diluted sodium hydroxide (NaOH) solution as the neutralizing solution22. Upon contact with bromine, the NaOH solution reacts to produce relatively harmless sodium bromide (NaBr) and sodium hypobromite (NaOBr), effectively reducing the harmful effects of bromine.

[0069] 1. Container material

[0070] Neutralizing solution 22: Diluted sodium hydroxide (NaOH) solution, with a recommended concentration of 0.5% to 2%.

[0071] Container material: Use chemically resistant materials such as high-density polyethylene (HDPE) or polypropylene (PP) containers.

[0072] Reaction mechanism: The diluted NaOH solution neutralizes bromine through the following chemical reaction:

[0073] Br2 + 2NaOH → NaBr + NaOBr + H2O

[0074] The sodium bromide (NaBr) and sodium hypobromite (NaOBr) generated by this reaction are relatively harmless, and the products exist in the form of solids or dissolved in water to form a solution. Sodium hypobromite also has a slight oxidizing effect, which can further treat a small amount of residual organic matter.

[0075] 2. Preparation of diluted NaOH solution

[0076] Dissolve solid sodium hydroxide in deionized water at a ratio of 0.5% to 2%. For example, to prepare 1 liter of 1% NaOH solution, dissolve 10 grams of sodium hydroxide in 990 milliliters of deionized water. Make sure the sodium hydroxide is completely dissolved and the solution is uniform.

[0077] 3. Operation steps

[0078] Complete safety protection equipment must be worn before operation.

[0079] Place the bromine bottle: Carefully place the bromine bottle 12 in the appropriate position in the first container 1.

[0080] Add NaOH solution: Pour the prepared diluted NaOH solution into the second container 2, ensuring that the liquid level is at least 5 cm higher than the bottom end of the gas guide channel 3 to ensure that the bottom end outlet of the gas guide channel 3 is completely immersed in the NaOH solution, forming an effective water seal.

[0081] Connect the containers: Connect the through hole 23 of the first container 1 and the second container 2, ensuring that the bottom end outlet of the gas guide channel 3 of the first container 1 is completely immersed in the NaOH solution.

[0082] 4. Maintenance and replacement

[0083] Check the liquid level: Due to evaporation of the solution and chemical reaction, the liquid level of the NaOH solution may gradually decrease. Check the liquid level regularly and replenish the solution in time to maintain the appropriate height.

[0084] Replace the solution: It is recommended to replace the NaOH solution every few weeks or according to the frequency of use. In particular, when the solution color changes or becomes turbid, replace it in time to ensure that the neutralization ability is not affected.

[0085] The entire set of devices must be placed in a well-ventilated place and managed safely.

[0086] Example 2: A diluted sodium bicarbonate (NaHCO3, commonly known as baking soda) solution is used as a neutralizing solution. 22 When the NaHCO3 solution comes into contact with bromine, it reacts to produce sodium bromide (NaBr), carbon dioxide (CO2), and water (H2O), effectively reducing the harmful effects of bromine.

[0087] 1. Container material

[0088] Neutralizing solution 22: Diluted sodium bicarbonate (NaHCO3) solution, with a recommended concentration of 5% to 10%.

[0089] Container material: corrosion-resistant materials, such as polyethylene (PE) or polypropylene (PP) containers. Because sodium bicarbonate is milder, the container material requirements are not as strict as those for sodium hydroxide.

[0090] Reaction Mechanism: Dilute NaHCO3 solution neutralizes bromine through the following chemical reaction:

[0091] 2NaHCO3+Br2→2NaBr+CO2+H2O

[0092] The sodium bromide (NaBr) produced by this reaction is relatively harmless and exists as a solid or dissolved in water to form a solution. Carbon dioxide and water do not pose any additional hazards. The reaction process is mild and relatively safe for the environment and operators.

[0093] 2. Preparation of Diluted NaHCO3 Solution

[0094] Dissolve sodium bicarbonate in deionized water at a ratio of 5% to 10%. For example, to prepare 1 liter of 5% NaHCO₃ solution, dissolve 50 grams of sodium bicarbonate in 950 milliliters of deionized water. Ensure that the sodium bicarbonate is completely dissolved and the solution is homogeneous.

[0095] 3. Operation steps

[0096] Complete safety protection equipment must be worn before operation.

[0097] Place the bromine bottle: Carefully place the bromine bottle 12 in the appropriate position in the first container 1.

[0098] Add NaHCO3 solution: Pour the prepared diluted NaHCO3 solution into the second container 2, ensuring that the liquid level is at least 5 cm higher than the bottom of the gas guide channel 3 to ensure that the bottom outlet of the gas guide channel 3 is completely immersed in the NaHCO3 solution to form an effective water seal.

[0099] Connecting containers: Connect the first container 1 to the through hole 23 of the second container 2, ensuring that the bottom outlet of the gas guide channel 3 on the first container 1 is completely immersed in the NaHCO3 solution.

[0100] 4. Maintenance and replacement

[0101] Check the liquid level: The liquid level of the NaHCO3 solution may gradually drop due to evaporation and reaction. Check the liquid level regularly and replenish the solution in time to maintain the appropriate height.

[0102] Replace the solution: It is recommended to replace the NaHCO3 solution every few weeks or according to the frequency of use. Especially when the solution changes color or becomes turbid, replace it in time to ensure that the neutralization ability is not affected.

[0103] The entire device must be placed in a well-ventilated area and managed safely.

[0104] Example 3: Use a diluted sodium sulfite (Na2SO3) solution as the neutralizing solution. 22 When the Na2SO3 solution comes into contact with bromine, it reacts to produce sodium bromide (NaBr) and sodium sulfate (Na2SO4), effectively neutralizing the bromine and reducing its harmful effects.

[0105] 1. Container material

[0106] Neutralizing solution 22: diluted sodium sulfite (Na2SO3) solution, with a recommended concentration of 1% to 5%.

[0107] Container material: Due to the reducing nature of sodium sulfite, it is recommended to use chemically resistant containers such as high-density polyethylene (HDPE) or polypropylene (PP).

[0108] Reaction Mechanism: Dilute Na2SO3 solution neutralizes bromine through the following chemical reaction:

[0109] Br2+Na2SO3→2NaBr+Na2SO4

[0110] This reaction produces sodium bromide (NaBr) and sodium sulfate (Na2SO4), both of which are relatively harmless. The products exist in the form of solids or dissolved in water to form solutions. The reaction process is mild and easy to control.

[0111] 2. Preparation of Diluted Na2SO3 Solution

[0112] Dissolve sodium sulfite in deionized water at a ratio of 1% to 5%. For example, to prepare 1 liter of 5% Na2SO3 solution, dissolve 50 grams of sodium sulfite in 950 milliliters of deionized water. Ensure that the sodium sulfite is completely dissolved and the solution is uniform.

[0113] 3. Operation steps

[0114] Complete safety protection equipment must be worn before operation.

[0115] Place the bromine bottle: Carefully place the bromine bottle 12 in the appropriate position in the first container 1.

[0116] Add Na2SO3 solution: Pour the prepared diluted Na2SO3 solution into the second container 2, ensuring the liquid level is at least 5 cm higher than the bottom end of the gas guide channel 3 to ensure that the bottom end outlet of the gas guide channel 3 is completely immersed in the Na2SO3 solution, forming an effective water seal.

[0117] Connect containers: Connect the through hole 23 of the first container 1 and the second container 2, ensuring that the bottom end outlet of the gas guide channel 3 of the first container 1 is completely immersed in the Na2SO3 solution.

[0118] 4. Maintenance and replacement

[0119] Check liquid level: Due to evaporation and reaction of the solution, the liquid level of the Na2SO3 solution may gradually decrease. Regularly check the liquid level and replenish the solution in time to maintain the appropriate height.

[0120] Replace the solution: Replace the Na2SO3 solution every few weeks or according to the frequency of use. Especially when the solution changes color or becomes turbid, replace it in time to ensure that the neutralization ability is not affected.

[0121] The entire set of devices must be placed in a well-ventilated place and managed safely.

[0122] In the above three examples, the specific concentration of dilution depends on the application scenario and the neutralization requirement. For large-scale operations, sodium bicarbonate (NaHCO3) and sodium sulfite (Na2SO3) and other mild solutions are suitable for situations with high safety requirements, while for more rapid neutralization requirements in industrial environments, sodium hydroxide (NaOH) is still the most effective choice.

[0123] In addition to the three chemical solutions mentioned above, there are other options for neutralizing bromine. Other options include but are not limited to sodium bisulfite (NaHSO3), sodium carbonate (Na2CO3, soda ash), sodium thiosulfate (Na2S2O3), ammonia (NH4OH), sodium borohydride (NaBH4), etc.

[0124] In order to reduce the corrosiveness or toxicity of chemicals and still effectively neutralize bromine, appropriate dilution of certain chemicals is an effective strategy. Sodium hydroxide (NaOH), sodium sulfite (Na2SO3), sodium bisulfite (NaHSO3), sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) are more suitable for dilution. The solution after dilution can reduce the corrosiveness and toxicity of itself while still maintaining good ability to neutralize bromine.

[0125] When selecting a suitable container material for storing the above-mentioned chemicals, it is important to consider the properties of each substance, particularly whether the stored chemical is corrosive. Considering the cost of the container material and its compatibility with various chemicals, high-density polyethylene (HDPE) or polypropylene (PP) is the optimal material choice for the first container 1, second container 2, and air guide channel 3.

[0126] The beneficial effects of the bromine storage device 100 of this solution are as follows:

[0127] 1. Safety and operability design

[0128] Absolute leakage control design: By completely immersing the outlet end of the sole gas discharge channel (the gas outlet end) in the neutralizing liquid, bromine cannot leak directly into the air. This design maintains a more effective gas seal even for opened bromine bottles, resolving the issue of leaks caused by the inability to reseal the bottle neck after unsealing. It is suitable for storing both opened and sealed bromine bottles.

[0129] Fully automatic neutralization: If a bromine bottle leaks, this solution allows the leaked bromine to directly contact the neutralizing solution and react rapidly. This automated treatment system, which requires no mechanical devices, significantly improves the safety of the container and prevents serious leaks even when no one is monitoring.

[0130] Maximum Flexibility: The first container features customizable recesses for bromine bottles of varying sizes, allowing for safe and secure storage of bottles of varying diameters and heights. By properly controlling the recess diameter and depth, the stability and safety of the bottles are ensured, minimizing the risk of moving the container. Furthermore, the second container offers the flexibility to select the appropriate neutralizing solution based on actual needs.

[0131] The design embodies simplicity and low cost: bromine does not directly come into contact with the container, so there is no need to consider whether the container is compatible with bromine; the bromine bottles storing bromine do not need to be immersed in chemical solutions such as neutralizing liquid, so there is no need to consider whether the chemical solutions are compatible with the bromine bottles. This greatly simplifies the design steps of the bromine storage device and reduces the container material selection standards, thereby reducing production costs.

[0132] Efficient connection design: After the first and second containers are connected using a simple and effective step assembly support, the outlet end of the air guide channel can be completely immersed in the neutralizing liquid, which combines ease of operation with reliability during high-frequency use.

[0133] 2. Environmental impact: Through this design, most of the leaked bromine is absorbed and treated by the neutralization solution, significantly reducing bromine pollution to the air and environment. This not only meets environmental requirements but also enhances the company's social responsibility image.

[0134] 3. Economic Benefits: This solution is significantly cheaper than current commercial bromine storage systems. The container lacks any mechanical structure. The material selection and structural design ensure its durability, reducing the need for regular maintenance or replacement of mechanical consumables, thereby lowering long-term operating costs.

[0135] 4. Practicality: This solution is simple in design and easy to operate, requiring no extensive technical training. The container is lightweight, and the first container is equipped with a handle for easy movement, making it suitable for frequent access and storage of bromine bottles in laboratories or industrial settings.

[0136] 5. Wide application: Although the above embodiment is used for the storage and treatment of bromine, the structural design of this solution can also be applied to the storage and leakage control of other highly volatile, highly corrosive or toxic gases, and is not limited to the storage of bromine.

[0137] In summary, this solution provides a simple and effective way to store bromine. It can not only reduce the volatilization of bromine through physical barriers, but also reduce its toxicity and irritation through chemical neutralization reactions, and even convert the volatilized toxic gas into harmless products, ensuring storage safety. It effectively makes up for the shortcomings of current bromine sealed containers and provides further protection for the safe storage and management of toxic chemicals in industry and laboratories.

[0138] This solution has multiple advantages such as clever structural design, convenient operation, safe use and environmental friendliness, which enhances the potential of this solution in market application.

That is, the top wall of the second container 2 can also serve as the supporting structure. When in use, the first container 1 can be directly placed on the top wall of the second container 2, and the second container 2 as a whole supports the first container 1.
