Description

Technical Field

[0001] This application relates to the field of gas-liquid separation technology, and particularly to gas-liquid separation devices and electrolytic gas generation equipment. Background Technology

[0002] Electrolysis is the process of passing an electric current through an electrolyte solution or a molten substance, causing a redox reaction at the cathode and anode. Electrolytic gasification equipment refers to equipment that produces gas from a liquid feedstock by means of the electrolysis phenomenon. Typical electrolytic gasification equipment includes equipment for producing hydrogen and oxygen by electrolyzing water. Other examples include electrolytic chlorination and ammonia production.

[0003] Since the raw materials used in electrolysis are liquid, it is inevitable that some of the liquid raw materials will be mixed into the gas during the gas production process. Therefore, it is necessary to perform gas-liquid separation treatment on the electrolysis products.

[0004] Therefore, many existing electrolytic gasification devices are equipped with gas-liquid separators to separate the gas. Many gas-liquid separation devices rely on the centrifugal force of a swirling flow to adhere the liquid to the wall surface, and then rely on gravity to recover the liquid. This method is energy-intensive and not well-suited for small-scale electrolytic gasification devices.

[0005] In view of this, this application proposes a gas-liquid separation device and an electrolytic gas generation equipment. Summary of the Invention

[0006] To solve, or at least partially solve, the above-mentioned technical problems, this application provides a gas-liquid separation device, comprising:

[0007] The raw material tank is used to hold liquid raw materials and is connected to the liquid inlet of the gas generating mechanism of the equipment.

[0008] The air outlet channel has an air outlet at one end connected to the air outlet of the gas generating mechanism and an exhaust port at the other end.

[0009] The gas-liquid separator is connected to the gas outlet channel through a connection port to recover liquid entrained in the gas. The gas-liquid separator is also connected to the raw material tank to regulate the liquid level in the gas-liquid separator.

[0010] The solenoid valve is installed on the air outlet channel and located between the exhaust port and the connection port.

[0011] During operation, the solution in the raw material tank flows into the gas generating mechanism of the equipment through the inlet. The gas generating mechanism produces gas by electrolyzing the raw material. The gas passes through the outlet of the gas-liquid separation tank. Because the gas-liquid separation tank provides a relatively large space, the gas undergoes a process similar to adiabatic expansion within this space, resulting in gas cooling. This cooling process causes the vapor, i.e., the liquid component, carried in the gas to condense. The condensed liquid condenses into water droplets on the tank wall and falls downwards under gravity, gradually filling the gas-liquid separation tank. The periodic closing of the solenoid valve blocks the gas outlet, allowing the gas to expand within the gas-liquid separation tank and push the condensed liquid back into the raw material tank, thus achieving gas-liquid separation in the small electrolytic gas generator. This also prevents poor condensation due to excessive liquid in the gas-liquid separation tank during the gas-liquid separation process, as well as the problem of liquid overflow.

[0012] Optionally, a one-way valve is provided on the connecting channel between the gas-liquid separator and the raw material tank to allow liquid to flow into the raw material tank in one direction.

[0013] The presence of the one-way valve prevents liquid raw materials in the raw material tank from flowing into the gas-liquid separator through the connecting channel. Under the action of gas pressure in the gas-liquid separator, the accumulated water flows back to the raw material tank, ensuring that the gas-liquid separator is emptied each time the solenoid valve is closed.

[0014] Optionally, it also includes: a housing;

[0015] The air outlet channel includes a first hose, an internal airflow channel, and a second hose connected in sequence. The air outlet is located at the first hose, and the exhaust port is located at the second hose.

[0016] The raw material tank, gas-liquid separation tank, and internal airflow channel are all installed on the tank body. The internal airflow channel and the gas-liquid separation tank are arranged side by side, and the connection port penetrates the tank wall between the gas-liquid separation tank and the internal airflow channel.

[0017] The second hose is positioned directly above the opening of the gas-liquid separator.

[0018] When the solenoid valve is open, the usable gas can be discharged sequentially through the first hose, the internal airflow channel, the second hose, the solenoid valve, and the exhaust port. During the gas discharge process, gas-liquid separation occurs as the gas passes through the gas-liquid separation tank. The resulting liquid returns to the raw material tank through the connecting channel under the influence of gravity. The solenoid valve then closes after a period of time. At this time, the internal gas pressure of the gas-liquid separator increases, and the resulting liquid returns to the raw material tank through the connecting channel under the combined effects of gravity and gas pressure, effectively preventing the potential accumulation and overflow of water in the gas-liquid separation tank.

[0019] Optionally, it also includes: a thermoelectric cooler; the cold end of the thermoelectric cooler is used to reduce the temperature of the gas-liquid separation tank.

[0020] By cooling the gas-liquid separation tank with a semiconductor refrigeration chip, the liquefaction rate of water vapor is accelerated, thereby improving the liquid recovery rate.

[0021] Optionally, it may further include: a first thermally conductive component that contacts the cold end of the semiconductor cooling chip, the first thermally conductive component forming at least part of the tank wall of the gas-liquid separation tank, or the first thermally conductive component wrapping around the tank wall of the gas-liquid separation tank.

[0022] The first heat-conducting component can increase the cooling rate of the gas-liquid separation tank, increase the liquefaction rate of water vapor, and further accelerate the gas-liquid separation speed.

[0023] Optionally, the hot end of the semiconductor cooling chip is used to raise the temperature of the raw material bath.

[0024] Increasing the temperature of the liquid raw material in the raw material tank can accelerate the gas generation rate in the gas generation mechanism, causing the gas inside the gas-liquid separation tank to increase rapidly and the pressure to rise quickly. This allows for faster recovery of the liquefied water vapor, effectively solving the problem of accumulated liquid overflow.

[0025] Optionally, it may further include: a second heat-conducting component that contacts the hot end of the semiconductor cooling chip, the second heat-conducting component forming at least part of the wall of the raw material tank, or the second heat-conducting component being inserted into the raw material tank.

[0026] The second heat-conducting component contacts the hot end of the semiconductor cooling chip, which can accelerate the rate at which the temperature of the liquid raw material in the raw material tank rises, thereby facilitating the generation of gas by the gas generating mechanism.

[0027] Optionally, the raw material tank and the gas-liquid separation tank are spaced apart from each other, or a heat insulation wall is provided between the raw material tank and the gas-liquid separation tank.

[0028] The raw material tank and the gas-liquid separation tank are set apart from each other or share a common heat insulation wall, so that even if there is a temperature difference between the raw material tank and the gas-liquid separation tank, they will not affect each other.

[0029] This application also proposes an electrolytic gas generation device, comprising: a gas generating mechanism and the aforementioned gas-liquid separation device.

[0030] This electrolytic gasification equipment collects gas at a higher rate than conventional gasification equipment, and can also effectively prevent the problem of liquid accumulation and overflow.

[0031] Optionally, it also includes: a timer, which is communicatively connected to the gas generating mechanism and the solenoid valve respectively. The timer is used to provide a countdown for the working time of the gas generating mechanism and to send a time signal to the solenoid valve.

[0032] The working time of the gas generating mechanism can be set to be an integer multiple of a first preset time; when the countdown is an integer multiple of the first preset time, the solenoid valve closes and remains closed for a second preset time, and then reopens.

[0033] By using a timer in conjunction with a solenoid valve, the system automatically closes at an integer multiple of the first preset time and then opens again at the second preset time, allowing for periodic gas collection and saving manpower and resources.

[0034] The gas-liquid separation device disclosed in the embodiments of this application cleverly utilizes electrolysis to generate gas, increasing the pressure in the gas-liquid separation tank, so that the liquefied water vapor can be quickly returned to the raw material tank, achieving gas-liquid separation with extremely low energy consumption and extremely simple device compared to conventional gas-liquid separation devices.

[0035] The electrolytic gas generation equipment disclosed in this application has a higher gas collection rate and lower energy consumption compared with the prior art, and also effectively solves the problem of liquid accumulation and overflow. Attached Figure Description

[0050] The inventors of this application have discovered that existing gas-liquid separation devices often produce gases containing a large amount of vapor components from the raw material liquid. Furthermore, the various separation devices used to remove these raw material liquid components often suffer from high energy consumption and complex design, making them unsuitable for small-scale electrolytic gasification equipment.

[0051] Therefore, this application provides a gas-liquid separation device and an electrolytic gas generation equipment. The following is a detailed description of this application with reference to the accompanying drawings.

[0052] Implementation Method 1

[0053] The first embodiment of this application discloses a gas-liquid separation device, see reference. Figure 1 and Figure 2 The device includes:

[0054] Raw material tank 10 is used to hold liquid raw materials and is connected to the liquid inlet of the gas generating mechanism 1 of the equipment.

[0055] The gas outlet channel 20 has one end connected to the gas outlet 11 of the gas generating mechanism and the other end has an exhaust port 201.

[0056] The gas-liquid separation tank 30 is connected to the gas outlet channel 20 through the connection port 50 for recovering liquid entrained in the gas. The gas-liquid separation tank 30 is also connected to the raw material tank 10 to adjust the liquid level of the gas-liquid separation tank 30.

[0057] Solenoid valve 40 is installed on the air outlet passage 20 and located between the exhaust port 201 and the connection port 50.

[0058] During operation, the solution in the raw material tank 10 flows into the gas generating mechanism 1 of the equipment through the inlet. The gas generating mechanism 1 generates gas by electrolyzing the raw material. A typical electrolysis reaction can be the production of hydrogen or oxygen by electrolyzing water; that is, the gas generating mechanism 1 is a mechanism for producing hydrogen and oxygen by water electrolysis. The generated gas passes through the connection port 50 of the gas outlet channel 20 and then through the gas-liquid separation tank 30.

[0059] Because the gas-liquid separator 30 provides a relatively large space, the gas will undergo a process similar to adiabatic expansion within this space, resulting in gas cooling. This cooling process will cause the vapor, i.e., the liquid component, carried in the gas to condense.

[0060] The condensed liquid condenses into water droplets on the wall of the gas-liquid separation tank 30 and falls downwards under gravity, gradually filling the tank. Furthermore, by periodically closing the solenoid valve 40, the gas outlet is blocked, allowing the gas to expand within the tank 30 and push the condensed liquid back into the raw material tank 10. This process achieves gas-liquid separation in a small-scale electrolytic gas generation device with extremely low energy consumption and a very simple apparatus.

[0061] It is particularly worth mentioning that the technical solution of this application, by promoting the reflux of the condensed liquid, can also prevent the poor condensation effect and the problem of liquid overflow that may be caused by excessive liquid in the gas-liquid separation tank 30 during the gas-liquid separation process.

[0062] For a more detailed description of the shape of the liquid separation device in this application, please refer to... Figure 2 and Figure 5 In the embodiments of this application, the raw material tank 10 further includes a accommodating space 103, a recessed portion 104, and a protruding portion 105. The raw material tank 10 has an accommodating space 103 inside for storing the raw material solution.

[0063] A recessed portion 104 is provided on one of the longer sides of the raw material tank 10. Since symmetrical shapes are generally more aesthetically pleasing and convenient for sales, the recessed portion 104 is located in the middle of one of the longer sides of the raw material tank 10, thus ensuring the overall aesthetics of the device. Furthermore, the long side portion 1042 of 104 is recessed towards the accommodating space 103, and the two short side portions 1041 form bends inward (i.e., towards the accommodating space 103) at their respective connections with the long side portion 1042.

[0064] Figure 1In the recessed portion 104, there are two protrusions 105 and two bends 106, symmetrically arranged on both sides of the recessed portion 104. The top view shape of the protrusion 105 is approximately "L". One end of the protrusion 105 is connected to the end of 1041 away from 1042, and the other end of the protrusion 105 is connected to the bend 106. The top view shape of the bend 106 is approximately "S".

[0065] It should be noted that, although Figure 4 The recess 104 shown is rectangular in top view, but in actual design, the position and shape of the recess 104 are not limited and can be designed according to actual needs. The shape and number of the protrusion 105 and the curved part 106 can also be adjusted according to actual needs.

[0066] See Figure 1 and Figure 2 In the embodiments of this application, the air outlet channel 20 includes a first hose 202, an internal airflow channel 203, and a second hose 204 connected in sequence.

[0067] The air outlet 11 is located at the air inlet end of the first hose 202. The air outlet end of the first hose 202 is connected to the lower end of the airflow channel 203 inside the box. The airflow channel 203 inside the box is connected to the gas-liquid separation tank 30 through the connection port 50. The opening of the gas-liquid separation tank 30 is directly opposite the air inlet end of the second hose 204. The air outlet end of the second hose 204 is connected to the exhaust port 201 through the solenoid valve 40.

[0068] The above-described scheme also includes a housing 2. The raw material tank 10, the gas-liquid separation tank 30, and the internal airflow channel 203 are all located inside the housing 2. The internal airflow channel 203 and the gas-liquid separation tank 30 can be arranged side by side, and the connection port 50 can penetrate the tank wall between the gas-liquid separation tank 30 and the internal airflow channel 203, or it can be located at the top of the gas-liquid separation tank 30.

[0069] In addition, this application also includes a connecting channel 101 for connecting the raw material tank 10 and the gas-liquid separation tank 30. It should be noted that, however, the connection can also be achieved by simply perforating the housing 2 without a separate connecting channel 101. This application will illustrate the solution with the connecting channel 101 as an example.

[0070] To facilitate understanding of the implementation scheme of this application, the technical solution of this application will be described in detail step by step below:

[0071] 1. Under the influence of gravity, the liquid flows into the interior of the gas generating mechanism 1 through the inlet. When the gas generating mechanism 1 is working, it electrolyzes the liquid and generates gas. It is possible that gas is generated at both the positive and negative electrodes. Unused gas can be directly discharged through other designated channels (not shown), while useful gas can be discharged sequentially through the first hose 202, the internal airflow channel 203, the second hose 204, the solenoid valve 40, and the exhaust port 201.

[0072] 2. During the gas discharge process, gas-liquid separation occurs when the gas passes through the gas-liquid separation tank 30. The resulting liquid returns to the raw material tank 10 under the action of gravity through the connecting channel 101. Over time, water may accumulate in the gas-liquid separation tank, or it may overflow due to poor backflow.

[0073] 3. Therefore, the solenoid valve 40 can be closed. When the solenoid valve 40 is closed, it is equivalent to the exhaust port 201 being blocked, while the gas generating mechanism 1 continues to generate gas continuously. Under this premise, the continuously generated gas increases the gas pressure above the gas-liquid separation tank 30, thereby pushing the liquid in the gas-liquid separation tank 30 back into the raw material tank 10.

[0074] 4. Reopen the solenoid valve 40 to release the gas in the gas-liquid separation tank 30, thereby continuing to produce gas.

[0075] Implementation Method 2

[0076] It is readily understood that in the first embodiment of this application, the connecting channel 101 functions similarly to a U-shaped tube to balance the liquid level. Through the connecting channel 101, the liquid raw material can flow back towards the raw material tank. However, also through the connecting channel 101, each time the solenoid valve is reopened, the liquid raw material will flow back to the gas-liquid separator 30 due to liquid level balancing, bringing it to the same liquid level as the raw material tank.

[0077] In view of this, the second embodiment of this application provides a gas-liquid separation device, which is an improvement on the gas-liquid separation device in the first embodiment. The main improvement is as follows: [See details below] Figure 2 As shown, a one-way valve 102 is provided on the connecting channel 101 between the gas-liquid separator 30 and the raw material tank 10 to make the process of liquid flowing into the raw material tank 10 one-way.

[0078] The one-way valve 102 allows the liquefied liquid in the gas-liquid separation tank 30 to flow into the raw material tank 10 through the connecting channel 101. However, the liquid raw material in the raw material tank 10 is not allowed to flow into the gas-liquid separation tank 30 through the connecting channel 101. In this way, under the gas pressure in the gas-liquid separation tank 30, the accumulated water flows to the raw material tank 10, ensuring that the gas-liquid separation tank 30 is cleared each time the solenoid valve 40 is closed.

[0079] Preferably, in this application, the one-way valve 102 is located in the middle of the communication channel 101.

[0080] To facilitate understanding of the embodiments of this application, this embodiment also provides a detailed step-by-step description of the technical solutions of this application:

[0081] 1. Under the influence of gravity, the liquid flows into the interior of the gas generating mechanism 1 through the inlet. When the gas generating mechanism 1 is working, it electrolyzes the liquid and generates gas. It is possible that gas is generated at both the positive and negative electrodes. Unused gas can be directly discharged through other designated channels (not shown), while useful gas can be discharged sequentially through the first hose 202, the internal airflow channel 203, the second hose 204, the solenoid valve 40, and the exhaust port 201.

[0082] 2. During the gas discharge process, gas-liquid separation occurs when the gas passes through the gas-liquid separation tank 30. The resulting liquid returns to the raw material tank 10 under the action of gravity through the connecting channel 101. Over time, water may accumulate in the gas-liquid separation tank, or it may overflow due to poor backflow.

[0083] 3. Therefore, solenoid valve 40 can be closed. When solenoid valve 40 is closed, it is equivalent to blocking exhaust port 201, while gas generating mechanism 1 continues to generate gas continuously. Under this premise, the continuously generated gas increases the air pressure above gas-liquid separation tank 30, thereby pushing the liquid in gas-liquid separation tank 30 back into raw material tank 10. Under the action of the check valve, the complete discharge of liquid in gas-liquid separation tank 30 can be achieved.

[0084] 4. Reopen the solenoid valve 40 to release the gas in the gas-liquid separation tank 30, thereby continuing to produce gas.

[0085] Implementation Method 3

[0086] The electrolysis of liquid feedstocks generates a large amount of heat. This heat often increases the temperature of the liquid feedstock, which in turn promotes the electrolysis rate.

[0087] However, excessively high temperatures will obviously cause more liquid to be carried out by the prepared gas, and the high temperature of the gas-liquid separation tank 30 will also make it difficult to separate the liquid.

[0088] In view of this, a third embodiment of this application provides a gas-liquid separation device, which is an improvement upon the gas-liquid separation device in the first or second embodiment, see reference. Figure 4 or Figure 5 The main improvement is that its raw material tank 10 and gas-liquid separation tank 30 are arranged at intervals.

[0089] In particular, see Figure 1 A heat insulation wall 31 is provided between the raw material tank 10 and the gas-liquid separation tank 30, meaning that the shared tank wall of the raw material tank 10 and the gas-liquid separation tank 30 has a good heat insulation effect. The heat insulation wall 31 can block heat transfer between the raw material tank 10 and the gas-liquid separation tank 30, thereby improving the separation efficiency.

[0090] Implementation Method 4

[0091] The inventors of this application found during testing of the gas-liquid separation device in the above embodiments that the gas-liquid separation effect is quite obvious and can effectively prevent liquid overflow.

[0092] Based on the aforementioned technical solutions, the fourth embodiment of this application provides a further improved gas-liquid separation device, which includes a semiconductor cooling chip 60.

[0093] See Figure 3 , Figure 4 and Figure 5 As shown, the thermoelectric cooler 60 can be fixed to the outer wall of the gas-liquid separation tank 30 by adhesive bonding, or by other methods such as screws or bolts. When fixing the thermoelectric cooler 60 with screws, blind holes can be drilled in the wall of the gas-liquid separation tank 30 to ensure the wall's isolation effect. Typically, when the thermoelectric cooler 60 is installed, the tank wall of the gas-liquid separation tank 30 can be made of a heat-conducting metal material, with the cold end of the thermoelectric cooler 60 positioned in close contact with the tank wall.

[0094] In this embodiment of the application, the cold end 61 of the semiconductor cooling chip 60 can be used to reduce the temperature of the gas-liquid separation tank 30.

[0095] Alternatively, the thermoelectric cooler 60 can be longitudinally attached to the inner wall edge of the gas-liquid separation tank 30. It can be understood that when the thermoelectric cooler 60 is attached to the inner wall of the gas-liquid separation tank 30, its hot end is in close contact with the tank wall, and the tank wall can be connected to an external heat-dissipating area, such as the metal casing of the gas-liquid separation device, to facilitate heat transfer.

[0096] The inventors of this application have discovered that increasing the temperature of the liquid raw material in the raw material tank 10 is a better way to improve the gas generation rate of the gas generating mechanism 1. Generally speaking, the gas generating mechanism 1 itself generates heat for the liquid raw material in the raw material tank 10, but if the liquid raw material can be further heated, the gas electrolysis efficiency can be further improved.

[0097] Therefore, furthermore, excess heat from the hot end 62 of the semiconductor cooling chip 60 can be used to raise the temperature of the raw material bath 10. For example, see... Figure 4 and Figure 5 As shown, the semiconductor cooling chip 60 can be installed on the common tank wall of the raw material tank 10 and the gas-liquid separation tank 30 while ensuring airtightness.

[0098] In other words, the hot end 62 of the semiconductor cooling chip 60 is located inside the raw material tank 10, and the cold end 61 is located inside the gas-liquid separation tank 30; thus, it is used to lower the temperature of the gas-liquid separation tank 30 on one side and to raise the temperature of the raw material tank 10 on the other side.

[0099] According to the scheme of this application, the cold end 61 of the semiconductor refrigeration chip 60 can lower the temperature of the gas-liquid separation tank 30, thereby improving the gas-liquid separation efficiency. The hot end 62 can raise the temperature of the liquid raw material in the raw material tank 10, thereby improving the efficiency of the ionization reaction. In other words, this application fully utilizes the unique temperature separation effect of the cold end 61 and the hot end 62 of the semiconductor refrigeration chip 60 to achieve multi-level optimization.

[0100] To facilitate understanding of the embodiments of this application, this embodiment also provides a detailed step-by-step description of the technical solutions of this application:

[0101] 1. Under the influence of gravity, the liquid flows from the raw material tank 10 into the gas generating mechanism 1 through the inlet. When the gas generating mechanism 1 is working, it electrolyzes the liquid and generates gas. It is possible that gas is generated at both the positive and negative electrodes. Unused gas can be directly discharged through other designated channels (not shown), while useful gas can be discharged sequentially through the first hose 202, the internal airflow channel 203, the second hose 204, the solenoid valve 40, and the exhaust port 201. In this embodiment, the raw material tank 10 is heated by the hot end of the semiconductor cooling chip 60, thereby improving the electrolysis efficiency.

[0102] 2. During the gas discharge process, gas-liquid separation occurs when the gas passes through the gas-liquid separation tank 30. In this embodiment, the gas-liquid separation tank 30 is cooled by utilizing the cold end of the semiconductor cooling chip 60, thereby significantly improving the efficiency of gas-liquid separation. The resulting liquid returns to the raw material tank 10 under the action of gravity through the connecting channel 101. Over time, water may accumulate in the gas-liquid separation tank 30, or it may overflow due to poor backflow.

[0103] 3. Therefore, solenoid valve 40 can be closed. When solenoid valve 40 is closed, it is equivalent to blocking exhaust port 201, while gas generating mechanism 1 continues to generate gas continuously. Under this premise, the continuously generated gas increases the air pressure above gas-liquid separation tank 30, thereby pushing the liquid in gas-liquid separation tank 30 back into raw material tank 10. Under the action of the check valve, the complete discharge of liquid in gas-liquid separation tank 30 can be achieved.

[0104] 4. Reopen the solenoid valve 40 to release the gas in the gas-liquid separation tank 30, thereby continuing to produce gas.

[0105] Implementation Method 5

[0106] In the fourth embodiment of this application, the temperature of the gas-liquid separation tank 30 and the raw material tank is changed by means of the semiconductor cooling chip 60 itself. However, relying solely on the semiconductor cooling chip 60 imposes relatively strict limitations on the shape of the housing 2.

[0107] In view of this, the fifth embodiment of this application provides a gas-liquid separation device. The difference between the fifth embodiment and the fourth embodiment is that the fifth embodiment further includes a first heat-conducting component 71 and / or a second heat-conducting component 72.

[0108] See Figure 5 The first heat-conducting component 71 contacts the cold end 61 of the semiconductor cooling chip 60. The first heat-conducting component 71 forms at least part of the tank wall of the gas-liquid separation tank 30, or the first heat-conducting component 71 wraps around the tank wall of the gas-liquid separation tank 30.

[0109] The second heat-conducting component 72 is in contact with the hot end 62 of the semiconductor cooling chip 60. The second heat-conducting component 72 forms at least part of the tank wall of the raw material tank 10, or the second heat-conducting component 72 is inserted into the raw material tank 10.

[0110] Optionally, the first heat-conducting component 71 and the second heat-conducting component 72 are made of metal alloy materials with good thermal conductivity, such as aluminum alloy materials, or alloy materials formed by adding other chemical elements to iron, aluminum or tin.

[0111] Implementation Method Six

[0112] The sixth embodiment of this application provides an electrolytic gas generation device, see reference. Figure 7 and Figure 7 The electrolytic gas generation equipment includes a gas generating mechanism 1 and any one of the gas-liquid separation devices in Embodiments 1 to 5.

[0113] Because it is equipped with any of the gas-liquid separation devices in Embodiments 1 to 5, the electrolytic gas generation equipment disclosed in this application is superior to the gas generation equipment in the prior art and has a faster collection rate.

[0114] To facilitate control of the working cycle of the gas generating mechanism 1, the electrolytic gasification device may further include a timer 80 fixedly mounted on the side of the device near its lower end. In this embodiment, the timer 80 is communicatively connected to both the gas generating mechanism 1 and the solenoid valve 40. The timer 80 is used to provide a countdown for the working time of the gas generating mechanism 1.

[0115] It is easy to understand that when a timer 80 is provided, it can be considered to use the timer 80 to simultaneously provide a control signal to the solenoid valve 40. However, the applicant has found that, as a small electrolytic gasification device, it is typically used on and off as needed. This raises the issue of the timing of the control signal transmission.

[0116] For example, if the solenoid valve 40 is set to close once every 20 minutes based on the received time signal, the user may need to pause use for various reasons after 15 minutes of operation. In this case, the user is very likely to shut down the electrolysis gas generator.

[0117] When the device is turned on again, timer 80 is reset. After the user restarts the device, solenoid valve 40 will close at 35 minutes (15 minutes + 20 minutes). Repeated timeouts may cause liquid to overflow.

[0118] To solve this problem, a temporary register would likely be needed to record the operating status of timer 80 when it is powered off, which would increase the complexity and cost of the device.

[0119] In view of this, in this embodiment, the working time of the gas generating mechanism 1 can be set to be an integer multiple of the first preset time; when the countdown is an integer multiple of the first preset time, the solenoid valve 40 closes and remains closed for a second preset time, and then the solenoid valve 40 reopens.

[0120] This embodiment clearly explains the working principle of the timer as follows:

[0121] 1. Taking a minimum working time of 20 minutes as an example, the user can set the working time of the gas generating mechanism 1 to 20 minutes, 40 minutes, 60 minutes, etc. when starting the machine. Therefore, regardless of the working time set by the user, the solenoid valve will close and remain closed for the second preset time when the machine is started to discharge any liquid that may be present in the gas-liquid separation tank 30.

[0122] 2. During the continuous operation of the gas generating mechanism 1, whenever the time nodes of 20 minutes, 40 minutes, 60 minutes, etc. are reached, the solenoid valve 40 will close and continue for a second preset time to drain any liquid that may be present in the gas-liquid separation tank 30.

[0123] In this way, no matter how long the user sets the working time, and no matter when the user turns off the gas generating mechanism 1, the technical solution of the embodiment of this application can ensure that the liquid in the gas-liquid separation tank 30 will not overflow.

[0124] Preferably, in this embodiment, the first preset time is 10-20 minutes, and the second preset time is 5-10 seconds. Generally speaking, a preparation time of about 10-60 minutes is suitable for small gas generators. Furthermore, based on the gas generation efficiency, 5-10 seconds is sufficient to drain the liquid from the air-liquid separation tank 30, and the user will not be annoyed by excessively long gas generation interruptions.

[0125] Implementation Method Seven

[0126] To provide a more detailed description of the electrolytic gas generation equipment, Embodiment Six of this application provides an improved electrolytic gas generation equipment. A liquid raw material inlet 91 is provided at the top of the electrolytic gas generation equipment and at the top of the raw material tank 10. The liquid raw material inlet 91 is detachably connected to a liquid raw material inlet cover 92. An exhaust port cover 93 is detachably provided on the side of the top of the electrolytic gas generation equipment away from the liquid raw material inlet 91.

[0127] See Figure 6 or Figure 7 Although the liquid raw material inlet cover 92 and the exhaust port cover 93 are shown as circular, they are not limited to being circular and can be designed according to actual conditions.

[0128] Specific detachable connections include, but are not limited to, the following methods:

[0129] A first thread is formed on the inner wall of the liquid raw material inlet 91, and a second thread that mates with the first thread is formed on the circumference of the liquid raw material inlet cover 92. A protrusion is provided at the center of the top of the liquid raw material inlet cover 92 for easy gripping. By gripping the protrusion and rotating the liquid raw material inlet cover 92, the liquid raw material inlet cover 92 can be tightened or loosened.

[0130] Alternatively, one end of the liquid raw material inlet cover 92 is hinged to the top of the electrolytic gasification equipment via a pin and can cover the liquid raw material inlet 91.

[0131] Similarly, the detachable vent cover 93 can be connected to the liquid raw material inlet 91 and the liquid raw material inlet cover 92 in the same way.

[0132] It is understood that in this embodiment, a control chip can be installed on the top of the device to control the automatic opening and closing of the solenoid valve 40. How to obtain the signal from the timer 80 through the control chip and control the opening and closing of the solenoid valve 40 based on that signal is a relatively conventional existing technology, so this principle will not be described in detail here.

[0133] In the electrolytic gas generation device of this application embodiment, the timer 80 provides a countdown for the working time of the gas generating mechanism 1 and sends a time signal to the solenoid valve 40. When the countdown is an integer multiple of 20 minutes, the solenoid valve 40 closes and remains closed for 10 seconds, and then reopens to discharge the electrolyzed gas.

[0134] When electrolysis produces gas, a lot of vaporized water vapor is mixed in. The water vapor is liquefied in the gas-liquid separation tank 30 and flows back to the raw material tank under the action of hydrogen generated by the gas generating mechanism 1 for secondary electrolysis.

[0135] Finally, it should be noted that those skilled in the art will understand that many technical details have been presented in the embodiments of this application to facilitate a better understanding of the present application. However, even without these technical details and various changes and modifications based on the above embodiments, the technical solutions claimed in the claims of this application can be substantially achieved. Therefore, in practical applications, various changes can be made to the above embodiments in form and detail without departing from the spirit and scope of this application.
