Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a water-reactive gas release tester. Background Technology

[0002] In the fields of chemistry, materials and environmental testing, the water reaction gas emission tester is a key device used to study the gas produced by the reaction of substances with water. It is widely used in scenarios such as safety testing of lithium battery materials, evaluation of chemical catalysts, and stability analysis of nanomaterials.

[0003] Currently, CN215493391U discloses a water-reactive gas release test apparatus, including a reaction chamber, a replenishment chamber, an exhaust pipe, a filter assembly, an outlet pipe, and a sealing plug. The replenishment chamber and exhaust pipe are both installed above the reaction chamber. The bottom of the replenishment chamber is the outlet pipe, with its top connected to the replenishment chamber and its bottom inserted into the reaction chamber. The exhaust pipe is L-shaped in this apparatus, with one end inserted into the reaction chamber and the other end located outside the reaction chamber. The end outside the reaction chamber is connected to the filter assembly. The bottom of the outlet pipe is located below the bottom of the exhaust pipe. A sealing plug is installed on the top of the reaction chamber. Both the outlet pipe and the exhaust pipe are connected to the filter assembly. The sealing plug facilitates testing, and the filter assembly prevents the sample reaction from releasing heat and the moisture carried during the violent reaction. In addition, the filter assembly can prevent external moisture from entering the instrument, thus improving the instrument's service life. Although this device has a filter assembly at the end of the exhaust pipe, it only uses a simple desiccant and molecular sieve to adsorb moisture. It lacks effective interception of aerosols, small solid particles, and volatile sublimations generated during the reaction. The liquid outlet pipe adopts a straight cylindrical design and is inserted into the reaction liquid, causing violent local reactions and affecting experimental results. The sealing relies solely on the sealing plug, which is prone to leakage after long-term use due to material aging or thermal expansion and contraction.

[0004] Therefore, it is necessary to provide a new water-induced gas release test instrument to solve the above-mentioned technical problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 ,in, Figure 1 A schematic diagram of a preferred embodiment of the water-reactive gas release tester provided by this utility model; Figure 2 for Figure 1 The diagram shown is a structural schematic of the fluid replenishment device. Figure 3 for Figure 1 The diagram shown is a structural schematic of the condenser tube. Figure 4 for Figure 1 The diagram shows the structure of the filtration device. Figure 5 for Figure 1 The diagram shows a cross-sectional view of the pressing component. Figure 6 for Figure 1 The diagram shows the structure of the pressing component.

[0019] In the specific implementation process, such as Figures 1-6 As shown, the water-reacting gas release test apparatus comprises four main parts: a liquid replenishment device 1, a reaction vessel 2, a condenser 3, and a filter device 4. The liquid replenishment device 1 is used to accurately add the reaction liquid to the reaction vessel 2; the reaction vessel 2 is the site where the substance reacts with water; the condenser 3 cools the gas produced by the reaction, causing some of the condensable substances to liquefy; the filter device 4 intercepts and dries the cooled gas, ultimately obtaining a relatively pure gas for subsequent analysis.

[0020] The replenishment device 1 includes a replenishment chamber 8 and an outlet pipe 7. The replenishment chamber 8 is used to store the reaction liquid to be added. Its shape can be designed as a cuboid or cylinder according to actual needs. A control valve 12 is provided on one side of the replenishment chamber 8. The output end of the control valve 12 is connected to the bottom of the replenishment chamber 8. By operating the control valve 12, the outflow speed and flow rate of the reaction liquid can be precisely controlled, thereby achieving precise control of the reaction process. The outlet pipe 7 has a conical structure, which helps the liquid to flow out evenly. The side wall of the outlet pipe 7 is provided with an annular groove 9. This groove can increase the structural strength of the outlet pipe 7 and also play a certain role in buffering and guiding the liquid flow. Multiple equally spaced holes are opened at the bottom of the outlet pipe 7 so that the liquid can flow into the reaction container 2 in a dispersed form, avoiding uneven reaction caused by excessive local liquid flow. The outlet is in contact with the top of the reaction container 2, and a sealing ring 13 is provided at the top of the outlet to ensure the sealing between the replenishment device 1 and the reaction container 2, preventing liquid leakage or the entry of outside air during the reaction process from affecting the reaction results.

[0021] The reaction vessel 2 includes a conical section and a cylindrical section, with the cylindrical section located at the top of the conical section. This structural design increases the volume of the reaction vessel 2 and facilitates the discharge and collection of gas. A splash guard 10 is installed inside the reaction vessel 2, positioned between the cylindrical and conical sections. The splash guard 10 has multiple equidistantly distributed holes. When the liquid replenishment device 1 adds liquid to the reaction vessel 2, the splash guard 10 can effectively block the splashing caused by the liquid impacting the reaction liquid surface. At the same time, the holes on it will not affect the normal escape of gas during the reaction process. An exhaust pipe 11 is provided on the side wall of the reaction vessel 2, located at the bottom of the splash guard 10. This design ensures that the gas generated by the reaction can fully pass through the reaction area before exiting the reaction vessel 2, making the reaction more complete. At the same time, the position of the exhaust pipe 11 can also prevent the gas from carrying too much unreacted liquid or foam.

[0022] The condenser tube 3 includes a cylindrical tube 14 and a spiral tube 15. The cylindrical tube 14 is sleeved on the outside of the spiral tube 15. The cylindrical tube 14 has an inlet pipe 16 and an outlet pipe 17 on both sides. Cooling water is introduced into the inlet pipe 16 and flows inside the cylindrical tube 14 to cool the reaction gas inside the spiral tube 15. The design of the spiral tube 15 increases the contact area and contact time between the gas and the cooling medium, improves the condensation effect, and enables the condensable substances in the reaction gas to be fully liquefied, reducing the burden on the subsequent filtration device 4.

[0023] The filtration device 4 includes an interception mechanism 5 and a drying mechanism 6. The bottom of the interception mechanism 5 is fixedly connected to the top of the drying mechanism 6. The interception mechanism 5 includes a top cover 18 and an interception chamber 19. The top cover 18 is threadedly connected to one side of the interception chamber 19. This connection method facilitates disassembly and installation, and makes it convenient to clean the inside of the interception chamber 19 and replace the interception material. A filter plate 20 is provided on the other side of the interception chamber 19. The filter plate 20 has multiple holes evenly distributed on it. When the reactive gas enters from one side of the interception chamber 19, the filter plate 20 can effectively intercept aerosols, small solid particles and volatile sublimations in the gas. To prevent impurities from entering the subsequent drying mechanism 6 and gas analysis system, thus affecting the accuracy of gas analysis, the drying mechanism 6 includes a pressing device and a drying chamber 22. One side of the drying chamber 22 is fixedly connected to the filter 20 to ensure that gas can smoothly enter the drying mechanism 6 from the interception mechanism 5. The other side of the drying chamber 22 is fixedly connected to one side of the pressing assembly 21. The pressing assembly 21 includes a base plate 23, a fixing post 24, a top plate 25, and two button pieces 26. One side of the base plate 23 is fixedly connected to the other side of the drying chamber 22, and the other side of the base plate 23 is fixedly connected to the fixing post 24. The fixed post 24 has two L-shaped grooves 27 at its bottom. The output ends of the two button pieces 26 slide within the two grooves 27 respectively. The fixed post 24 has protrusions 30 on both sides. The top plate 25 has two grooves 28, and the two protrusions 30 slide within the two grooves 28 respectively. The bottom of the top plate 25 has a locking groove 34. The button piece 26 includes a movable block 31, a locking block 32, and a spring 33. The movable block 31 slides within the groove 27. The top end of the movable block 31 has a locking block 32. The bottom of the movable block 31 has a groove 29. A spring is installed within the groove 29. When the desiccant in the drying chamber 22 needs to be replaced or the drying mechanism 6 needs to be maintained, the movable block 31 of the button 26 is pressed, and the locking block 32 overcomes the elastic force of the spring 33 and disengages from the locking groove 34. At this time, the top plate 25 can be moved to open the drying chamber 22 for relevant operations. After the operation is completed, the top plate 25 is reset, and the locking block 32 re-engages into the locking groove 34 under the action of the spring 33, thus sealing the drying mechanism 6. The drying chamber 22 is filled with desiccant to remove water vapor from the reaction gas and ensure that the collected gas has high purity.

[0024] The working principle provided by this utility model is as follows: When using this water-reaction gas release tester, the substance to be reacted is first placed in the reaction container 2. Then, the reaction liquid is slowly added to the reaction container 2 through the control valve 12 of the liquid replenishment device 1. The liquid flows evenly into the reaction container 2 through the liquid outlet pipe 7. The splash guard 10 prevents the liquid from splashing. The substance reacts with water in the reaction container 2, and the generated gas enters the condenser 3 through the exhaust pipe 11. In the condenser 3, the gas is cooled, and the condensable substances in it are liquefied. The cooled gas enters the filter device 4, first passes through the filter plate 20 of the interception mechanism 5 to remove impurities, and then enters the drying chamber 22 of the drying mechanism 6 to remove water vapor. Finally, a relatively pure gas is obtained for subsequent analysis.

[0025] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
