Description

Technical Field

[0001] This application relates to the field of safety protection equipment technology, and in particular to a flame arrester and a hydrogen-oxygen generator. Background Technology

[0002] Flame arresters in hydrogen-oxygen generators primarily prevent hydrogen combustion and backfire, inhibit the propagation of electrical sparks or flames, avoid potential explosion risks, and ensure the safety of equipment and personnel. Flame arresters can include separate flame arresters and water-sealed flame arresters, with the latter being a device that provides spark protection through a water seal.

[0003] Currently, existing water-sealed flame arresters typically involve simply introducing gas into a liquid. This results in significant fluctuations in the water seal level, and the gas easily forms bubbles or columns within the liquid, leading to uneven gas distribution. Consequently, the water seal cooling effect is inconsistent, reducing flame arresting efficiency. Furthermore, the accuracy of water seal level control is low, impacting the safety and reliability of the flame arrester. Utility Model Content

[0004] Based on this, a flame arrester and a hydrogen-oxygen generating device are provided.

[0005] In a first aspect, this application provides a flame arrester, comprising:

[0006] The cavity is equipped with a gas transmission chamber containing a regulating liquid. The gas transmission chamber is used to transmit the gas to be regulated so that the gas to be regulated can be regulated after contacting the regulating liquid.

[0007] A liquid level regulating component is installed in the cavity and is used to regulate the liquid level height in the gas transmission cavity.

[0008] A gas distributor is installed inside the gas transmission chamber and is used to disperse the gas to be regulated entering the gas transmission chamber.

[0009] In one embodiment, the cavity is provided with a first port and a second port, and the first port, the gas transmission cavity and the second port are connected.

[0010] The gas distributor is located between the first port and the second port, and is disposed adjacent to the first port.

[0011] In one embodiment, the flame arrester further includes a gas transmission conduit, the first end of which is provided with a gas output port;

[0012] The first end of the gas transmission pipe passes through the first port so that the gas output port is located inside the gas transmission chamber.

[0013] In one embodiment, the gas output port is directed toward the bottom surface of the gas transmission cavity.

[0014] In one embodiment, the gas transmission pipeline is equipped with an anti-backflow module;

[0015] The anti-backflow module is used to prevent the regulating liquid from flowing back from the gas transmission pipeline.

[0016] In one embodiment, the liquid level regulating component includes a liquid level feedback module, a drain switch, and a replenishment switch; the cavity is also provided with a third port and a fourth port;

[0017] The liquid level feedback module is located in the cavity, the drain switch is located at the third port, and the replenishment switch is located at the fourth port.

[0018] The liquid level feedback module connects the drain switch and the replenishment switch, and is used to control the opening and closing of the drain switch and the replenishment switch.

[0019] In one embodiment, the liquid level regulating assembly further includes a liquid level indicator disposed in the cavity, the liquid level indicator being used to display the liquid level height.

[0020] In one embodiment, the height of the bottom surface of the third port to the gas transmission cavity is less than the height of the bottom surface of the fourth port to the gas transmission cavity.

[0021] In one embodiment, the cavity is further provided with a fifth port, which is used to install a pressure relief switch;

[0022] The height of the bottom surface of the fifth port to the gas transmission cavity is greater than the height of the bottom surface of the second port to the gas transmission cavity.

[0023] In one embodiment, the flame arrester further includes a filter element;

[0024] The filter element is disposed inside the gas transmission chamber and located between the first port and the second port; the gas distributor is disposed adjacent to the second port.

[0025] The filter element is used to perform liquid filtration on the gas to be regulated that is transmitted from the gas transmission chamber to the second port.

[0026] Secondly, this application provides a hydrogen-oxygen generating apparatus, including a flame arrester as described in any of the above.

[0027] One of the above technical solutions has the following advantages and beneficial effects:

[0028] The aforementioned flame arrester includes a cavity, a liquid level regulating component, and a gas distribution component. The cavity is provided with a gas transmission chamber containing a regulating liquid. The gas transmission chamber is used to transmit the gas to be regulated so that the temperature of the gas to be regulated is regulated after contact with the regulating liquid. The liquid level regulating component is located in the cavity and is used to regulate the liquid level height of the regulating liquid in the gas transmission chamber. The gas distribution component is located in the gas transmission chamber and is used to disperse the gas entering the gas transmission chamber to achieve a water seal flame arrest for the gas to be regulated. This application incorporates a gas distributor within the gas transmission chamber. When the gas to be regulated is introduced into the gas transmission chamber, the gas distributor forcibly disperses the gas into fine bubbles, preventing the formation of large bubbles or gas columns in the regulating liquid that could cause the flame arrester's water seal to fail.

[0037] In addition, the term "multiple" should mean two or more.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] In one embodiment, such as Figure 1 As shown, a flame arrester is provided, including a cavity 10, a liquid level regulating component 20, and a gas distributor 30. The cavity 10 is provided with a gas transmission chamber 110, which contains a regulating liquid. The gas transmission chamber 110 is used to transmit the gas to be regulated so as to regulate the temperature of the gas after it comes into contact with the regulating liquid. The liquid level regulating component 20 is disposed in the cavity 10 and is used to regulate the liquid level in the gas transmission chamber 110. The gas distributor 30 is disposed in the gas transmission chamber 110 and is used to disperse the gas to be regulated entering the gas transmission chamber 110.

[0040] Flame arresters can be used in hydrogen-oxygen generators. They are used to seal the output gas of the generator with water to prevent flame ignition, thereby cooling and regulating the gas and preventing it from igniting or exploding. The gas to be regulated can be hydrogen-oxygen gas.

[0041] The cavity 10 can be a pressure vessel of regular or irregular shape; for example, it can be a cylindrical or square pressure vessel. Exemplarily, the bottom and top surfaces of the cavity 10 can be flat plates, and the cavity 10 contains a regulating liquid. The regulating liquid is a water-sealing liquid, such as water, or a mixture of water and ethylene glycol. A gas transmission chamber 110 is provided within the cavity 10, where the regulating liquid is stored, allowing the gas to be regulated transmitted through the gas transmission chamber 110 to contact the regulating liquid, thereby regulating the temperature of the liquid and achieving water-sealed flame arrest for the gas passing through the gas transmission chamber 110. Exemplarily, the transmission direction of the gas to be regulated in the gas transmission chamber 110 can be from the bottom to the top of the regulating liquid.

[0042] The liquid level regulating component 20 can be used to monitor the liquid level of the regulating liquid in the gas transmission chamber 110. It can also be used to adjust the liquid level height of the gas transmission chamber 110 based on the monitored liquid level. For example, since the liquid level regulating component 20 is located on one side of the chamber 10, it monitors the liquid level of the regulating liquid in the gas transmission chamber 110 and adjusts the liquid level height accordingly. For instance, if the liquid level in the gas transmission chamber 110 is too high, a portion of the regulating liquid is discharged; if the liquid level in the gas transmission chamber 110 is too low, a portion of the regulating liquid is added to the gas transmission chamber 110. This balances the liquid level in the gas transmission chamber 110, ensuring that the water seal liquid level is always maintained within the optimal range. This avoids the problem of increased gas flow resistance due to excessively high liquid levels or flame arrestor failure due to excessively low liquid levels, thereby improving the reliability and safety of the flame arrester.

[0043] The gas distributor 30 is used to disperse the gas to be regulated entering the gas transmission chamber 110, thereby forming fine bubbles. This prevents the gas to be regulated from forming a gas column in the regulating liquid of the gas transmission chamber 110, which could lead to water seal failure. It also prevents excessive fluctuations in the flame arrester's liquid level. The gas distributor 30 can be installed in the gas transmission chamber 110 by welding or snap-fitting. For example, if a first limiting mechanism is provided in the gas transmission chamber 110, the gas distributor 30 can be snap-fitted into the first limiting mechanism to fix the gas distributor 30 within the gas transmission chamber 110. In one example, the gas distributor 30 can be a mesh distributor, such as a stainless steel wire mesh distributor.

[0044] When the gas to be regulated enters the gas transmission chamber 110, it is dispersed by the gas distributor 30, forming tiny bubbles that are then transmitted through the regulating liquid. This prevents the flame arrester water seal from failing, increases the contact area between the gas to be regulated and the regulating liquid, thereby improving the cooling efficiency and flame-arresting effect of the water seal and ensuring that the flame-arresting capacity is consistent across all areas of the flame arrester liquid surface.

[0045] In the above embodiments, a gas transmission chamber 110 is provided through the cavity 10, and the regulating liquid is stored in the gas transmission chamber 110. The gas transmission chamber 110 is used to transmit the gas to be regulated so that the temperature of the gas to be regulated is regulated after contact with the regulating liquid. A liquid level regulating component 20 is provided in the cavity 10 and is used to regulate the liquid level height of the regulating liquid in the gas transmission chamber 110. A gas distributor 30 is provided in the gas transmission chamber 110 and is used to disperse the gas entering the gas transmission chamber 110 to achieve water seal flame arrest for the gas to be regulated. This application, by setting a gas distributor 30 in the gas transmission chamber 110, forces the gas to be regulated into fine bubbles when it is introduced into the gas transmission chamber 110. This avoids the formation of large bubbles or gas columns in the regulating liquid, which could cause the flame arrester's water seal to fail. It also reduces fluctuations in the water seal level, improves the uniformity of gas distribution, ensures consistent flame-arresting capacity in all areas of the flame arrester's liquid surface, and improves the consistency of the water seal cooling effect, thereby increasing the flame-arresting efficiency. Furthermore, by setting a liquid level adjustment component 20 in the chamber 10, the liquid in the gas transmission chamber 110 can be monitored. Based on the monitored liquid level, the liquid level in the gas transmission chamber 110 can be adjusted to ensure that the water seal level is always maintained within the optimal range, improving the accuracy of water seal level control and thus enhancing the safety and reliability of the flame arrester.

[0046] In one embodiment, such as Figure 1 and Figure 2 As shown, the cavity 10 is provided with a first port 120 and a second port 130, and the first port 120, the gas transmission cavity 110 and the second port 130 are connected; the gas distribution component 30 is located between the first port 120 and the second port 130, and the gas distribution component 30 is disposed adjacent to the first port 120.

[0047] The first port 120 and the second port 130 of the cavity 10 can be disposed on one side of the cavity 10. The first port 120 is used to input the gas to be regulated, and the second port 130 is used to output the regulated gas. The height of the first port 120 to the bottom surface of the gas transmission cavity 110 is less than the height of the second port 130 to the bottom surface of the gas transmission cavity 110. For example, the first port 120 can be disposed near the bottom surface of the cavity 10, and the second port 130 can be disposed near the top surface of the cavity 10.

[0048] The first port 120 is connected to the gas transmission chamber 110, and the second port 130 is also connected to the gas transmission chamber 110. The gas distributor 30 is disposed within the gas transmission chamber 110. The height of the gas distributor 30 to the bottom surface of the gas transmission chamber 110 is greater than the height of the first port 120 to the bottom surface of the gas transmission chamber 110, while the height of the gas distributor 30 to the bottom surface of the gas transmission chamber 110 is less than the height of the second port 130 to the bottom surface of the gas transmission chamber 110. Furthermore, the gas distributor 30 is disposed adjacent to the first port 120. Thus, when the gas to be regulated enters the gas transmission chamber 110 through the first port 120, it can be dispersed by the gas distributor 30, forming small bubbles. After being transported by the regulating liquid, the regulated gas is output through the second port 130. This avoids the formation of large bubbles or gas columns in the regulating liquid, which could cause the flame arrester water seal to fail. It also reduces fluctuations in the water seal level, improves the uniformity of gas distribution, ensures consistent flame arresting capacity across all areas of the flame arrester liquid surface, improves the consistency of the water seal cooling effect, and ultimately enhances the flame arresting efficiency.

[0049] In one embodiment, such as Figure 2 As shown, the flame arrester also includes a gas transmission pipe 40, and a gas output port 410 is provided at the first end of the gas transmission pipe 40; the first end of the gas transmission pipe 40 passes through the first port 120 so that the gas output port 410 is located in the gas transmission chamber 110.

[0050] The gas transmission pipe 40 is used to connect to the hydrogen-oxygen generator, thereby transmitting the gas to be regulated output from the hydrogen-oxygen generator to the gas transmission chamber 110.

[0051] The gas transmission pipe 40 has a first end and a second end. The first end of the gas transmission pipe 40 is provided with a gas output port 410 for outputting the gas to be regulated. The second end of the gas transmission pipe 40 is connected to a hydrogen-oxygen generator. By passing the first end of the gas transmission pipe 40 through the first port 120, the first end of the gas transmission pipe 40 is inserted into the gas transmission chamber 110, thereby placing the gas output port 410 within the gas transmission chamber 110. For example, the gas output port 410 is located near the bottom of the gas transmission chamber 110 and is positioned at the middle of the bottom of the gas transmission chamber 110. This allows the gas to be regulated output from the gas output port 410 to start transmission from the middle of the bottom of the gas transmission chamber 110, enabling the gas to be regulated to be more evenly dispersed after passing through the gas distributor 30, ensuring consistent flame-retardant capability across all areas of the flame arrester's liquid surface.

[0052] It should be noted that a sealing device is installed between the gas transmission pipeline 40 and the first port 120, for example, a sealing ring is installed between the gas transmission pipeline 40 and the first port 120 to prevent oil leakage between the gas transmission pipeline 40 and the first port 120, thereby improving the reliability of the flame arrester.

[0053] In one embodiment, such as Figure 2 As shown, the output direction of the gas output port 410 is towards the bottom surface of the gas transmission cavity 110.

[0054] For example, by setting the opening direction of the gas output port 410 to face the bottom surface of the gas transmission chamber 110, and thus making the output direction of the gas output port 410 face the bottom surface of the gas transmission chamber 110, the distribution of the gas to be regulated entering the gas transmission chamber 110 can be more uniform, reducing the fluctuation of the flame arrester liquid level, thereby improving the flame arresting performance.

[0055] In one embodiment, such as Figure 2 As shown, the gas transmission pipeline 40 is equipped with an anti-backflow module 420; the anti-backflow module 420 is used to prevent the regulating liquid from flowing back from the gas transmission pipeline 40.

[0056] The anti-backflow module 420 can be a one-way valve or a check valve.

[0057] Because the anti-backflow module 420 is installed on the gas transmission pipeline 40, when the gas to be regulated is injected into the gas transmission chamber 110, the gas to be regulated output from the hydrogen-oxygen generator enters through the second end of the gas transmission pipeline 40, activating the anti-backflow module 420, allowing the gas to be regulated to be transmitted to the gas output port 410, and then to the gas transmission chamber 110 through the gas output port 410. When the injection of the gas to be regulated into the gas transmission chamber 110 stops, the anti-backflow module 420 closes, thereby preventing the regulating liquid in the gas transmission chamber 110 from being drawn back into the gas transmission pipeline 40 for backflow, thus improving the reliability of the flame arrester.

[0058] In one embodiment, such as Figure 2 As shown, the liquid level regulating assembly 20 includes a liquid level feedback module 210, a drain switch 220, and a replenishment switch 230; the cavity 10 is also provided with a third port 140 and a fourth port 150; the liquid level feedback module 210 is located in the cavity 10, the drain switch 220 is located in the third port 140, and the replenishment switch 230 is located in the fourth port 150; the liquid level feedback module 210 is connected to the drain switch 220 and the replenishment switch 230, and the liquid level feedback module 210 is used to control the opening and closing of the drain switch 220 and the replenishment switch 230.

[0059] The liquid level feedback module 210 may include a liquid level detector or a pressure sensor. The liquid level feedback module 210 can be used to monitor the liquid level of the regulating liquid in the gas transmission chamber 110. The liquid level feedback module 210 can also control the opening and closing of the drain switch 220 and the replenishment switch 230 based on the monitored liquid level. When the drain switch 220 is open, the regulating liquid in the gas transmission chamber 110 is drained; when the drain switch 220 is closed, the draining of the regulating liquid in the gas transmission chamber 110 is stopped. When the replenishment switch 230 is open, the regulating liquid in the gas transmission chamber 110 is replenished; when the replenishment switch 230 is closed, the replenishment of the regulating liquid in the gas transmission chamber 110 is stopped.

[0060] The third port 140 and the fourth port 150 are located on one side of the cavity 10. The third port 140 is connected to the gas transmission cavity 110 and is connected to the third port 140 via the drain switch 220. The third port 140 is used to drain the regulating liquid in the gas transmission cavity 110. The fourth port 150 is connected to the gas transmission cavity 110 and is connected to the fourth port 150 via the replenishment port. The fourth port 150 is used to replenish the regulating liquid in the gas replenishment cavity.

[0061] The liquid level feedback module 210 is located on one side of the cavity 10. For example, the liquid level feedback module 210 can be connected to the gas transmission cavity 110 inside the cavity 10 through a hollow pipe, so that the real-time liquid level in the gas transmission cavity 110 can be detected through the liquid level feedback module 210.

[0062] Based on the liquid level feedback module 210 connected to the drain switch 220 and the replenishment switch 230, the liquid level feedback module 210 monitors the liquid level of the regulating liquid in the gas transmission chamber 110, and controls the opening and closing of the drain switch 220 and the replenishment switch 230 according to the monitored liquid level. For example, when the liquid level of the regulating liquid in the gas transmission chamber 110 is too high, the drain switch 220 is opened and the replenishment switch 230 is closed, thereby draining a portion of the regulating liquid from the gas transmission chamber 110 and bringing the regulating liquid in the gas transmission chamber 110 to a balance. When the liquid level of the regulating liquid in the gas transmission chamber 110 is too low, the drain switch 220 is closed and the replenishment switch 230 is opened, thereby replenishing a portion of the regulating liquid into the gas transmission chamber 110 and bringing the regulating liquid in the gas transmission chamber 110 to a balance. This achieves liquid level balance in the gas transmission chamber 110, ensuring that the water seal liquid level is always maintained within the optimal range. This avoids the problem of increased gas flow resistance due to excessively high liquid level or flame arrestor failure due to excessively low liquid level, thereby improving the reliability and safety of the flame arrester.

[0063] In one embodiment, the liquid level regulating assembly 20 further includes a liquid level indicator disposed in the cavity 10, which is used to display the liquid level height.

[0064] The level indicator can be a magnetic float level indicator. By installing a level indicator on one side of the cavity 10, operators can directly observe the level of the regulating liquid in the gas transmission cavity 110, thus improving operational convenience.

[0065] In another example, the level indicator can also be a display screen. For example, the level indicator is connected to the level feedback module 210, and the level feedback module 210 can display the monitored level height through the level indicator.

[0066] In one embodiment, such as Figure 2 As shown, the bottom height of the third port 140 to the gas transmission cavity 110 is less than the bottom height of the fourth port 150 to the gas transmission cavity 110.

[0067] By setting the bottom height of the third port 140 to the gas transmission chamber 110 to be less than the bottom height of the fourth port 150 to the gas transmission chamber 110, the fourth port 150 is higher than the third port 140, thereby facilitating the discharge of regulating liquid from the gas transmission chamber 110 and the replenishment of regulating liquid into the gas transmission chamber 110. For example, the bottom height of the third port 140 to the gas transmission chamber 110 is greater than the bottom height of the first port 120 to the gas transmission chamber 110, and the bottom height of the fourth port 150 to the gas transmission chamber 110 is less than the bottom height of the second port 130 to the gas transmission chamber 110.

[0068] In one embodiment, such as Figure 2 As shown, the cavity 10 is also provided with a fifth port 160, which is used to install a pressure relief switch 170; the height of the bottom surface of the fifth port 160 to the gas transmission cavity 110 is greater than the height of the bottom surface of the second port 130 to the gas transmission cavity 110.

[0069] The fifth port 160 is a pressure relief port, used to install the pressure relief switch 170. When the pressure relief switch 170 is open, the gas transmission chamber 110 releases pressure to the outside. The pressure relief switch 170 can be a pressure relief valve; for example, it can be an open safety valve or a closed safety valve.

[0070] For example, the fifth port 160 may be located on the top surface of the cavity 10. For instance, the fifth port 160 is located at the center of the top surface of the cavity 10. When the pressure in the gas transmission cavity 110 exceeds a set value, the pressure relief switch 170 is activated, thereby preventing the pressure in the gas transmission cavity 110 from becoming too high, thus improving the safety of the flame arrester.

[0071] In one embodiment, such as Figure 2As shown, the flame arrester also includes a filter element 50; the filter element 50 is disposed in the gas transmission chamber 110 and located between the first port 120 and the second port 130; the gas distributor 30 is disposed adjacent to the second port 130; the filter element 50 is used to perform liquid filtration on the gas to be regulated transmitted from the gas transmission chamber 110 to the second port 130.

[0072] The filter element 50 can be a mesh filter element, such as a stainless steel filter screen. The filter element 50 is used to filter the liquid in the gas to be regulated transmitted from the gas transmission chamber 110 to the second port 130, thereby removing the liquid droplets carried by the gas to be regulated and greatly reducing the liquid content of the regulated gas output from the first port 120.

[0073] The filter element 50 can be installed in the gas transmission cavity 110 by welding or snap-fitting. For example, a second limiting mechanism is provided in the gas transmission cavity 110, and the filter element 50 is installed in the second limiting mechanism by snap-fitting to fix the filter element 50 in the gas transmission cavity 110.

[0074] For example, the height of the filter element 50 to the bottom surface of the gas transmission chamber 110 is greater than the height of the first port 120 to the bottom surface of the gas transmission chamber 110, and the height of the filter element 50 to the bottom surface of the gas transmission chamber 110 is less than the height of the second port 130 to the bottom surface of the gas transmission chamber 110. The filter element 50 is located adjacent to the second port 130. When the gas to be regulated enters the gas transmission chamber 110 through the first port 120, the gas to be regulated is first dispersed by the gas distributor 30, and then forms small bubbles before being transmitted through the regulating liquid. Then, the gas to be regulated is filtered by the filter element 50. The fine mesh structure of the filter element 50 effectively intercepts and removes the tiny droplets entrained in the gas, reducing the liquid content of the output regulated gas, thereby improving the reliability of the flame arrester.

[0075] For example, the filter element 50 is located between the second port 130 and the fourth port 150. By adding the filter element 50 near the second port 130, the tiny droplets entrained in the regulated gas output to the second port 130 can be effectively intercepted and removed, reducing the water content of the output gas, thereby meeting the application environment with high requirements for gas water content.

[0076] In one embodiment, a hydrogen-oxygen generating apparatus is also provided, including a flame arrester as described in any of the above embodiments.

[0077] The hydrogen-oxygen generating device may include a hydrogen-oxygen generator, which is connected to a flame arrester. The hydrogen-oxygen generator is used to supply the gas to be regulated to the flame arrester. For a detailed description of the flame arrester, please refer to the specific description of the flame arrester in the above embodiments; it will not be repeated here.

[0078] For example, the hydrogen-oxygen generator is connected to a cavity, which is equipped with a gas transmission chamber containing a regulating liquid. A liquid level regulating component is installed in the cavity, and a gas distributor is installed in the gas transmission chamber. The gas transmission chamber transmits the gas to be regulated so that the gas to be regulated will be regulated in temperature after contacting the regulating liquid. The liquid level regulating component regulates the liquid level in the gas transmission chamber. The gas distributor disperses the gas entering the gas transmission chamber to achieve a water seal flame arrestor for the gas to be regulated. This application incorporates a gas distributor within the gas transmission chamber. When the gas to be regulated is introduced into the gas transmission chamber, the gas distributor forcibly disperses the gas into fine bubbles, preventing the formation of large bubbles or gas columns in the regulating liquid that could cause the flame arrester's water seal to fail. This reduces fluctuations in the water seal level, improves the uniformity of gas distribution, ensures consistent flame-arresting capacity across all areas of the flame arrester's liquid surface, and enhances the consistency of the water seal's cooling effect, thereby improving flame-arresting efficiency. Furthermore, by incorporating a liquid level adjustment component within the chamber, the liquid level within the gas transmission chamber can be monitored. Based on the monitored liquid level, the liquid level height within the gas transmission chamber can be adjusted to ensure that the water seal level is always maintained within the optimal range, improving the accuracy of water seal level control and ultimately enhancing the safety and reliability of the hydrogen-oxygen generator.
