Description

Technical Field

[0001] This invention belongs to the field of primary battery technology, and specifically relates to a device and method for detecting the separation ratio of a gas-liquid separator used in an underwater activated aluminum-silver oxide battery. Background Technology

[0002] Silver oxide aluminum batteries offer advantages such as high specific energy, high voltage, good volume characteristics, high current density, low hydrogen evolution, and long-term storage. During discharge, these batteries produce aluminates and a small amount of hydrogen, requiring electrolyte circulation to remove the aluminates and carry away the hydrogen. The hydrogen is removed via cyclone centrifugation in a gas-liquid separator and must be promptly separated and discharged.

[0003] After the aluminum-silver oxide battery auxiliary system is assembled, the gas production of the battery body and the exhaust of the gas-liquid separator cannot be observed and measured, which makes it difficult to understand and analyze the various parameters of the gas-liquid separator and affects the optimization and improvement of the gas-liquid separator. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, one of the objectives of the present invention is to provide a device for detecting the separation ratio of a gas-liquid separator.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a gas-liquid separator separation ratio detection device, including a gas-liquid separator and a reaction tank connected to the inlet of the gas-liquid separator, and further including a motor pump, a flow meter and a gas-liquid mixer connected in sequence. The motor pump is connected to a clean water tank and an alkali tank respectively through a clean water valve and an alkali valve. The gas-liquid mixer is also connected to a gas flow meter and a reaction tank respectively. The gas flow meter is connected to a high-pressure gas tank. An aluminum plate is placed inside the reaction tank. The liquid outlet of the gas-liquid separator is connected to a gas collecting tank. The gas outlet of the gas-liquid separator is connected to a clean water valve and an alkali valve respectively.

[0006] The second objective of this invention is to provide a method for detecting the separation ratio of a gas-liquid separator, comprising the following steps:

[0007] A clean water experiment is conducted by opening the clean water valve. The clean water in the clean water tank enters the gas-liquid mixer via a motor pump and flow meter. It mixes evenly with the gas in the high-pressure gas tank, which enters the gas-liquid mixer via a gas flow meter, to form a gas-liquid two-phase liquid. The mixture with a known gas-liquid ratio output from the gas-liquid mixer passes through a reaction tank and then enters a gas-liquid separator for gas-liquid separation. The separated gas enters a gas collection tank, and the exhaust is monitored in real time. The liquid flows back to the clean water tank through the clean water valve. The separation ratio of the gas-liquid separator is detected by comparing the gas flow rate of the gas flow meter with the exhaust rate of the gas collection tank.

[0008] The high-pressure gas tank was closed and the alkaline solution valve was opened to conduct a battery reaction simulation test. The alkaline solution in the alkaline solution tank entered the gas-liquid mixer via a motor pump and flow meter, and then entered the reaction tank to react with the aluminum plate to produce microbubbles. The gas-liquid two-phase liquid after the microbubbles dissolved in the alkaline solution entered the gas-liquid separator to achieve gas-liquid separation, simulating the real working environment inside the battery. The separated gas entered the gas collection tank for drainage and gas collection, and the exhaust situation was observed in real time. The liquid flowed back to the clean water tank through the clean water valve. The separation performance of the gas-liquid separator was verified by observing the gas content in the alkaline solution tank.

[0009] The advantages and positive effects of this invention are as follows:

[0010] 1. This invention achieves the measurement of the inlet and outlet gas flow rates of a gas-liquid separator by using a combination of a gas flow meter and a gas collection tank, thereby accurately calculating the separation ratio of the gas-liquid separator;

[0011] 2. This invention can simulate the actual reaction conditions inside the battery and measure various parameters related to the performance of the gas-liquid separator. It can effectively analyze the rationality of the gas-liquid separator structural design and analyze the overall performance of the battery.

[0012] 3. The gas collecting tank of this invention, through the principle of communicating vessels and connected to an external transparent pipeline, allows for indirect observation of the water level inside the tank, thus realizing visualization of the exhaust volume of the gas-liquid separator;

[0013] 4. The present invention has a compact structure and adopts a multi-pipeline design, which can not only use clean water and compressed air to verify the gas-liquid separator's capabilities, but also verify the reliability of the gas-liquid separator's function under real battery reaction conditions.

Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other. Example 1

[0019] This invention proposes a simple and reliable device for detecting the separation ratio of a gas-liquid separator, such as... Figure 1 As shown, the present invention discloses a detection device for the separation ratio of a gas-liquid separator in an aluminum-silver battery, comprising a gas-liquid separator 10, a reaction tank 8 connected to the inlet of the gas-liquid separator 10, and several connecting pipes, and further comprising a motor pump 4, a flow meter 5, and a gas-liquid mixer 6 connected in sequence. The motor pump 4 is connected to a clean water tank 1 and an alkaline solution tank 2 respectively through a clean water valve K1 and an alkaline solution valve K2. The gas-liquid mixer 6 is also connected to a gas flow meter 7 and the reaction tank 8 respectively. The gas flow meter 7 is connected to a high-pressure gas tank 3. An aluminum plate 9 is placed inside the reaction tank 8. The liquid outlet of the gas-liquid separator 10 is connected to a gas collecting tank 11, and the gas outlet of the gas-liquid separator 10 is connected to a clean water valve K1 and an alkaline solution valve K2 respectively.

[0020] This invention enables the mixing of water and compressed air into a two-phase liquid by switching between the water valve K1 and the alkali valve K2. The actual separation capability of the gas-liquid separator 10 is examined by simulating the tiny bubbles generated in the reaction within the battery section.

[0021] The detection method proposed in this invention allows for direct observation of the gas-liquid separator's operation and the collection of key parameters for subsequent reference, laying the foundation for further improvement of the overall battery performance. Example 2

[0022] The present invention discloses a detection method for a detection device, comprising the following steps:

[0023] In the clean water experiment, the clean water valve K1 is opened to conduct the experiment. The clean water in the clean water tank 1 enters the circulation pipeline through the clean water valve K1, and enters the gas-liquid mixer 6 via the motor pump 4 and the flow meter 5. At the same time, the high-pressure gas in the high-pressure gas tank 3 enters the gas-liquid mixer 6 through the gas flow meter 7, forming a gas-liquid two-phase liquid. The mixture with a known gas-liquid ratio output from the gas-liquid mixer 6 enters the gas-liquid separator 10 after passing through the reaction tank 8 to achieve gas-liquid separation. The separated gas enters the gas collection tank 11, and the exhaust situation is observed in real time. The liquid flows back to the clean water tank 1 through the clean water valve K1. The separation ratio of the gas-liquid separator 10 is detected by comparing the gas flow rate of the gas flow meter 7 and the exhaust rate of the gas collection tank 11.

[0024] In the battery reaction simulation test, the high-pressure gas tank 3 was closed and the alkaline solution valve K2 was opened to conduct the battery reaction simulation test. The alkaline solution in the alkaline solution tank 2 entered the circulation pipeline through the alkaline solution valve K2, and entered the gas-liquid mixer 6 through the motor pump 4 and flow meter 5. Then it entered the reaction tank 8 and reacted with the aluminum plate 9 to produce microbubbles. The gas-liquid two-phase liquid after the microbubbles dissolved in the alkaline solution entered the gas-liquid separator 10 to achieve gas-liquid separation, simulating the real working environment inside the battery. The separated gas entered the gas collection tank 11 for drainage and gas collection. The exhaust situation was observed in real time. The liquid flowed back to the clear water tank 1 through the clear water valve K1. The separation performance of the gas-liquid separator 10 was verified by observing the gas content in the alkaline solution tank 2.

[0025] The present invention uses a water purification experiment to test the separation ratio of the gas-liquid separator 10 by comparing the air flow rate of the gas flow meter 7 and the exhaust volume of the gas collecting tank 11. A battery reaction simulation experiment verifies the separation performance of the gas-liquid separator 10 by observing the gas content in the alkaline solution tank 2.
