Description

Technical Field

[0001] The invention belongs to the field of chemical substance storage, relates to a bromine storage technology, and in particular to a novel bromine storage device. Background Art

[0002] Bromine (Br2) is a highly corrosive and toxic chemical widely used in industry and laboratories. Bromine is a liquid at room temperature and pressure with a strong pungent odor, and it will volatilize at room temperature to form reddish-brown toxic gases, which are seriously harmful to human health. This makes the storage and handling of bromine face many challenges, 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] In the process of storing bromine and bromine water, although sealed containers are usually used to reduce the leakage of volatile gases, due to the strong volatility of bromine, this sealing method is often difficult to completely prevent the emission of bromine. In order to overcome the problem of unreliable sealing of sealed containers, the current practice is to place the sealed containers for storing bromine in ventilated places, and also add wax seals and water seals to the sealed containers, such as:

[0004] (i) Use a container, store bromine in half of the container, and add pure water to the remaining space. Bromine is at the bottom of the container, and there is no other isolating material between it and the water. Bromine is basically insoluble when the aqueous solution is saturated. This water seal method is simple, convenient, and low-cost. Although it can reduce the volatilization and diffusion of bromine into the air to a certain extent, when the container is unsealed and the bromine is used, the remaining bromine in the container cannot be preserved in the same water seal method. In addition, plastic bottle caps and wax seals cannot completely prevent bromine gas from leaking out.

[0005] (ii) Use a double-layer container. Place the sealed container containing bromine inside another larger outer container. Pour a certain amount of water into the outer container and make the water level cover the mouth of the inner sealed container. Compared with a single container, this sealing method can reduce the volatilization and diffusion of bromine into the air to a greater extent. However, once the aqueous solution in the outer container is saturated with the leaked bromine, it will lose its function of preventing and isolating bromine. The sealing period is short and it is not suitable for long-term sealed storage.

[0006] In summary, in the process of storing bromine and bromine water, although sealed containers are usually used to reduce the leakage of volatile gases, due to the strong volatility of bromine, traditional sealing methods are often difficult to completely prevent the emission of bromine, which will not only cause laboratories or industrial sites to be filled with unpleasant odors, but may also pose a serious threat to the health of personnel and the safety of equipment. Therefore, it is urgent to propose a new type of bromine storage device to compensate for the shortcomings of sealed containers with more effective measures 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 a 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 containing chamber, and the neutralizing liquid containing chamber is used to contain the neutralizing liquid; the cavity wall of the second container is provided with a through hole communicating with the neutralizing liquid containing 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 containing chamber through the through hole and is immersed below the liquid level of the neutralization liquid. The air guide channel can direct 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 disposed 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 containing cavity.

[0015] In one embodiment, the support structure is a bracket structure that is separated from the second container, and the first container is disposed 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 arranged at 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 to 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 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 containing 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 containing chamber.

[0024] The bromine storage device provided by the present invention has a novel and reasonable structure. It adopts a double container structure of a first container and a second container, and uses the first container to store the bromine bottle, and uses the second container to hold the neutralizing liquid for neutralizing the leaked bromine gas, and then uses the air guide channel to specifically connect the first container and the second container. The design is ingenious, wherein 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 the only outlet, that is, the air guide channel, and enter the neutralizing liquid in the second container, and react with the neutralizing liquid. 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, and then cooperate with the neutralization effect of the subsequent neutralizing liquid, which can completely prevent the leakage of bromine gas into the air. Even for the unsealed bromine bottle, more efficient gas sealing can be achieved through the design, which solves the problem that the unsealed bromine bottle cannot be effectively sealed again, and is easy to leak, and is suitable for storing unsealed or still sealed bromine bottles.

[0025] If the bromine bottle leaks, the design of the present invention allows the leaked bromine to directly contact the neutralizing liquid and react quickly.

[0039] The following will be combined with the drawings in the embodiments 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.

[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] The present embodiment provides a bromine storage device 100, comprising a first container 1, a second container 2 and an air guide channel 3, wherein 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, and the bromine bottle 12 is a finished product, which often adopts a bottle body and a bottle cap to seal and store liquid bromine, but bromine gas leakage still occurs 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 connected to the bromine bottle receiving chamber 11, and the entire bromine bottle receiving chamber 11, except for the position where the air guide hole 13 is located, is a closed structure; the second container 2 is provided with a neutralization liquid receiving chamber 21, and the neutralization liquid receiving chamber 21 is used to hold a neutralization liquid 22, and the cavity wall of the second container 2 is provided with a through hole 23 connected to the neutralization liquid receiving chamber 21, and the through hole 23 is often located above the liquid level of the neutralization liquid 22 to prevent the neutralization liquid 22 from overflowing. The first container 1 and the second container 2 need to be used together. When in use, the air inlet end of the air guide channel 3 is in a sealed communication state with the air guide hole 13, and the air outlet end of the air guide channel 3 extends into the neutralizing liquid accommodating chamber 21 through the through hole 23 and is immersed in a distance below the liquid surface of the neutralizing liquid 22. The air guide channel 3 can guide the bromine gas leaked from the bromine bottle 12 into the neutralizing liquid 22 in a directional manner to neutralize the bromine gas through the neutralizing liquid 22. The neutralizing liquid 22 is a finished chemical solution, and the neutralization reaction process and principle 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, which effectively limits the diffusion path of the bromine gas, so that the leaked bromine gas can only be discharged through the only outlet, that is, 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 neutralization 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 to form an integral part. Figure 2 , Figures 4 to 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 on the top of 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 a straight pipe channel, a curved pipe channel, 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 containing cavity 21.

[0047] In one embodiment, if Figure 2 , Figures 4 to 6 As shown, the air guide channel 3 is preferably a straight tube channel, which can 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, and the air guide channel 3 is similar to a chimney, connected to the bottom of the first container 1, and the opening is downward. The air guide channel 3 is the only outlet of the first container 1 and also serves as a window for taking out the bromine bottle 12. The aperture size of the air guide channel 3 and the air guide hole 13 is moderate, and the bromine bottle 12 can be easily placed in a suitable position in the first container 1 for storage, or the bromine bottle 12 in the first container 1 can be taken out through this opening.

[0048] In one embodiment, the air guide channel 3 and the first container 1 can be assembled and connected by threaded tightening, interference fit, etc., or can be integrally formed. As a preferred solution, the air guide channel 3 and the first container 1 can be integrally formed so that there is no possibility of leakage at the junction of the air guide channel 3 and the first container 1.

[0049] In one embodiment, if Figure 3 to Figure 7 As shown, the second container 2 is preferably an open top container, and its open top is a through hole 23. Correspondingly, the aforementioned support structure is preferably a support step 24 arranged at the inner edge of the through hole 23, and 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 first container 1 is effectively supported by the structure of the second container 2 itself, and the first container 1 and the second container 2 can be assembled and combined in the upper and lower positions by a simple plug-in method to form a double-layer container. Based on this design, after the air guide channel 3 takes or places the bromine bottle 12, there is no need to use a special sealing device or additional treatment for the air guide channel 3. After the gravity of the first container 1 is used to simply and effectively complete the connection with the second container 2, the air outlet end of the air guide channel 3 can be immersed in the neutralization liquid to achieve a water seal. The separation of the first container 1 and the second container 2 is also very convenient, and the first container 1 can be directly taken away from the second container 2.

[0050] In one embodiment, if Figure 2 , Figure 4 and Figure 5 As shown, the air guide hole 13 is arranged on one side of the bottom cavity wall of the first container 1 (the left side in the figure), and the other side of the bottom cavity wall of the first container 1 (the right side in the figure) is used as a bromine bottle placement area 14, and the bromine bottle placement area 14 is provided with a placement groove 15 adapted to the bromine bottle 12. The bromine bottle 12 is placed in the placement groove 15, which can prevent the bromine bottle 12 from sliding, misalignment or even tipping over, which is conducive to improving the reliability, stability and safety of the storage of the bromine bottle 12 and reducing the risk when moving the container.

[0051] In one embodiment, if Figure 2 to Figure 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 one embodiment, the size specifications of all the placement grooves 15 can be exactly the same, but in order to be compatible with the storage of bromine bottles 12 of different specifications, the size specifications of all the placement grooves 15 can also be set to be not exactly the same or completely different, and the placement groove 15 can be customized according to the size specifications of the bromine bottle 12. Among them, the size specifications of the placement groove 15 generally refer to the groove width of the placement groove 15. For example, if the placement groove 1 is a cylindrical groove, its groove width is the cross-sectional diameter of the cylindrical groove; the groove depth of all the placement grooves 15 can be the same, and the groove depth of the placement groove 15 is mainly based on the ability 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 placement groove 15 adapted to the bromine bottle 12 with a diameter of 8.5 cm can be 11 cm, and the inner diameter can be 9 cm, while the outer diameter of the placement groove 15 adapted to 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 depth of the two placement grooves 15 can be set to 5 cm.

[0053] In one embodiment, if Figure 3 to Figure 6 As shown, the placement groove 15 is a cylindrical groove, and all the placement grooves 15 are arranged on the bottom cavity wall of the first container 1, and the groove bottoms of all the placement grooves 15 are arranged to protrude from the lower surface of the bottom cavity wall of the first container 1. As a preferred solution, the placement groove 15 is integrally formed on the bottom cavity wall of the first container 1. Figure 2 The arrangement of five placement grooves 15 is shown in the figure. In practical applications, the number and arrangement of the placement grooves 15 on the bottom cavity wall of the first container 1 can be flexibly adjusted as needed. The size of the grooves of the first container 1, including the depth, needs to be considered to be able to properly and safely place the bromine bottle.

[0054] In one embodiment, considering that the liquid level of the neutralizing liquid 22 in the second container 2 may gradually decrease during use, this embodiment preferably configures a liquid level detection device in the neutralizing liquid holding chamber 21, and the liquid level detection device is used to detect the liquid level height of the neutralizing liquid 22 in the neutralizing liquid holding chamber 21. Once the liquid level of the neutralizing liquid 22 is lower than the required height, the neutralizing liquid 22 can be replenished in time to maintain 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 repeated 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 taking and transferring the first container 1 and the second container 2. As a preferred solution, the handle 16 can be provided only on the first container 1, and the handles 16 are symmetrically provided 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 bolt connection or the like, or it can be integrally formed with the first container 1, such as Figure 2 As shown, it is a schematic diagram of the structure in which the handle 16 and the first container 1 are integrally formed. The integrally formed structure has higher strength, which is beneficial to extending 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 contours of the first container 1 and the second container 2 may be the same or different. As a preferred embodiment, Figure 1 to Figure 3 As shown, the first container 1 and the second container 2 of this embodiment are both prismatic containers, for example, both are quadrangular prisms. Considering that the first container 1 needs to be plugged and assembled with the support step 24 on the top of the second container 2, the bottom surface area of ​​the first container 1 is smaller than the top surface 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 clearance-matched, and the first container 1 can cover the entire through hole 23, as shown in FIG. Figure 1 , Figure 4 and Figure 5 shown.

[0057] In one embodiment, if neutralizing liquid 22 needs to be added to the second container 2, the first container 1 can be removed and the neutralizing liquid 22 can be added to the second container 2 through the through hole 23; accordingly, in order to facilitate the discharge of waste liquid after the neutralization reaction in the second container 2, a discharge port 25 can be set at the bottom of the side wall of the second container 2. The discharge port 25 is generally configured 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 of this scheme are as follows:

[0059] The first container 1 is a closed container, and the air guide channel 3 is similar to a chimney, connected to the bottom of the first container 1, and opened downward; a through hole 23 is set on the top of the second container 2, which is an open container for containing the neutralizing liquid 22. The opening size of the supporting step 24 at the through hole 23 of the second container 2 matches the bottom size of the first container 1 to ensure that the two parts can be connected and assembled.

[0060] The usage process is as follows:

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

[0062] (2) Next, ensure that the opening of the air channel 3 on the first container 1 faces downward, and place the bromine bottle 12 into the corresponding placement groove 15 in the bromine bottle receiving chamber 11 through the air channel 3. There are protruding handles 16 on both sides 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 plugged and connected with the support step 24 of the second container 2. 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 with 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 on the support step 24 of the second container 2, the contact position between the two can still allow gas to pass.

[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 react with the neutralizing liquid 22. 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 joint 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 ensure good ventilation.

[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 is described in detail below with reference to several specific examples.

[0068] Example 1: A diluted sodium hydroxide (NaOH) solution is used as a neutralizing solution 22. The NaOH solution reacts with bromine to produce relatively harmless sodium bromide (NaBr) and sodium hypobromite (NaOBr), thereby effectively reducing the hazards 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 Materials: Use chemically resistant materials such as high-density polyethylene (HDPE) or polypropylene (PP) containers.

[0072] Reaction Mechanism: 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) produced by this reaction are relatively harmless. The products exist in the form of solids or solutions dissolved in water. Sodium hypobromite also has a slight oxidizing effect and can further treat small amounts 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 homogeneous.

[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 at a suitable position in the first container 1 .

[0080] Adding NaOH solution: Pour the prepared diluted NaOH solution into the second container 2, and ensure that the liquid level is at least 5 cm higher than the bottom of the air guide channel 3, so as to ensure that the bottom outlet of the air guide channel 3 is completely immersed in the NaOH solution to form an effective water seal.

[0081] Connecting containers: Connect the first container 1 with 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 NaOH solution.

[0082] 4. Maintenance and replacement

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

[0084] Replacement of solution: It is recommended to replace the NaOH 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 capacity is not affected.

[0085] The entire device must be placed in a well-ventilated area and managed safely.

[0086] Example 2: Use a diluted sodium bicarbonate (NaHCO3, commonly known as baking soda) solution as a neutralizing solution 22. When the NaHCO3 solution comes into contact with bromine, it will react to produce sodium bromide (NaBr), carbon dioxide (CO2) and water (H2O), thereby effectively reducing the harm 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: Diluted NaHCO3 solution neutralizes bromine through the following chemical reaction:

[0091] 2NaHCO3+Br2→2NaBr+CO2+H2O

[0092] The sodium bromide (NaBr) generated by this reaction is relatively harmless. The product exists in the form of a solid or a solution dissolved in water. Carbon dioxide and water will not bring 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. Make sure the sodium bicarbonate is completely dissolved and the solution is uniform.

[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] Adding NaHCO3 solution: Pour the prepared diluted NaHCO3 solution into the second container 2, and ensure that the liquid level is at least 5 cm higher than the bottom of the gas guide channel 3, so as 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 with the through hole 23 of the second container 2, ensuring that the bottom outlet of the gas-guiding channel 3 on the first container 1 is completely immersed in the NaHCO3 solution.

[0100] 4. Maintenance and replacement

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

[0102] Replacement of 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 capacity is not affected.

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

[0104] Example 3: A diluted sodium sulfite (Na2SO3) solution is used as the neutralizing solution 22. The Na2SO3 solution reacts with bromine to generate sodium bromide (NaBr) and sodium sulfate (Na2SO4), thereby effectively neutralizing the bromine and reducing its harm.

[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: Diluted 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. Make sure 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] Adding Na2SO3 solution: Pour the prepared diluted Na2SO3 solution into the second container 2, and ensure that the liquid level is at least 5 cm higher than the bottom of the gas guide channel 3, so as to ensure that the bottom outlet of the gas guide channel 3 is completely immersed in the Na2SO3 solution to form an effective water seal.

[0117] Connecting containers: Connect the first container 1 with 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 Na2SO3 solution.

[0118] 4. Maintenance and replacement

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

[0120] Replacement of solution: It is recommended to 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 device must be placed in a well-ventilated area and managed safely.

[0122] In the above three examples, the specific dilution concentration depends on the application scenario and the neutralization requirements. For large-scale operations, mild solutions such as sodium bicarbonate (NaHCO3) and sodium sulfite (Na2SO3) are suitable for situations with higher safety requirements, while for faster 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, proper 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 substances that are more suitable for dilution. Their diluted solutions can reduce their own corrosiveness and toxicity while still maintaining good ability to neutralize bromine.

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

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

[0127] 1. Safety and operability design

[0128] Absolute leakage control design: By completely immersing the only gas discharge channel, that is, the outlet end of the gas guide channel, in the neutralizing liquid, bromine cannot leak directly into the air. Even for opened bromine bottles, this design can achieve more efficient gas sealing, solving the problem that the unsealed bromine bottles cannot be effectively sealed again and are prone to leakage. It is suitable for storing opened or still sealed bromine bottles.

[0129] Fully automatic neutralization function: If the bromine bottle leaks, the design of this solution allows the leaked bromine to directly contact the neutralization liquid and react quickly. This processing system, which does not require mechanical devices to achieve automation, greatly improves the safety performance of the container and ensures that serious leakage incidents can be avoided even when no one is monitoring.

[0130] Great flexibility: The first container can be customized with grooves of different sizes for bromine bottles, which can safely and securely store bromine bottles of different diameters and heights. By properly controlling the diameter and depth of the groove, the stability and safety of the bromine bottles during storage can be ensured, reducing the risk of moving the container. In addition, the second container can flexibly and flexibly select the appropriate neutralizing solution according to actual conditions.

[0131] The design embodies simplicity and low cost: bromine does not come into direct contact with the container, so there is no need to consider whether the container is compatible with the bromine; the bromine bottle storing bromine does not need to be immersed in chemical solutions such as neutralizing solution, so there is no need to consider whether the chemical solution is compatible with the bromine bottle, which 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 container and the second container are connected in a simple and effective way using step assembly support, it can ensure that the gas outlet end of the gas guide channel is completely immersed in the neutralizing liquid, combining ease of operation and reliability during high-frequency use.

[0133] 2. Environmental protection effect: Through the design of this solution, most of the leaked bromine will be absorbed and treated by the neutralization liquid, which greatly reduces the pollution of bromine to the air and environment. This not only meets environmental protection requirements, but also enhances the company's social responsibility image.

[0134] 3. Economic benefits: The production cost of this solution is much cheaper than the current commercial bromine storage system. The container of this solution does not have any mechanical structure. The material selection and structural design ensure the durability of the container, reducing the need for regular maintenance of equipment or replacement of mechanical consumables, thereby reducing long-term operating costs.

[0135] 4. Practicality: This solution is simple in design, easy to operate, and does not require excessive technical training. The container is light in weight, and the first container is equipped with a handle design, which is convenient for users to move and operate. It is suitable for frequent use and storage of bromine bottles in laboratories or industrial scenarios.

[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, not just limited to the storage of bromine.

[0137] In summary, this solution provides a simple and effective way to store bromine, which 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 volatile toxic gas into harmless products, ensuring the safety of storage. 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 the advantages of clever structural design, convenient operation, safe use, and environmental friendliness, which enhances the potential of this solution in market application.
