Description

Technical Field

[0001] This invention relates to the field of water replenishment and filtration technology, specifically to a water replenishment device for a carbon dioxide electrolysis humidifier. Background Technology

[0002] Carbon dioxide electrolysis is a process that uses green electricity to electrolyze and convert carbon dioxide emitted from factories into high-value-added chemicals such as formic acid and syngas, thus turning waste into treasure and consuming surplus electricity. During carbon dioxide electrolysis, carbon dioxide gas and water are input into an electrolysis reactor to produce chemicals such as formic acid, syngas, and ethylene. A humidifier is needed to supply water vapor to the reactor to maintain a stable relative humidity in the electrolysis environment. During operation, when the water level in the humidifier falls below the set low level, a water replenishment pump starts to add water to the humidifier. Water replenishment stops when the water level reaches the set high level.

[0003] In operation, humidifiers require water free of impurities, necessitating filtration during water replenishment. Existing water replenishment systems pump stored water into the humidifier via a pump, with a filter in the replenishment line. However, these filters are prone to clogging after prolonged use, disrupting normal water replenishment and causing moisture buildup that can harm the humidifier. Replacing the filter requires stopping the water replenishment process, which is cumbersome. Furthermore, the sudden start of the pump during replenishment creates a significant water pressure surge at the beginning, causing a sudden increase in water pressure within the humidifier and affecting the overall system's normal operation. Summary of the Invention

[0004] The purpose of this invention is to solve at least one of the technical problems in the prior art mentioned above, and to provide a water replenishment device for a carbon dioxide electrolysis humidifier.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] A water replenishment device for a carbon dioxide electrolysis humidifier includes a water storage tank, a water replenishment pump, a filter device, and a buffer device. A water pump pipe is installed on the water storage tank and connected to the inlet of the water replenishment pump. A water delivery pipe is connected to the outlet of the water replenishment pump and connected to the filter device. The filter device filters the flowing water. A connecting pipe is connected to the outlet of the filter device, and the end of the connecting pipe furthest from the filter device is connected to the buffer device. The buffer device buffers sudden increases in water pressure. The outlet of the buffer device is connected to the water replenishment pipe, which is connected to the water replenishment port of the humidifier to deliver water to the humidifier.

[0007] Furthermore, the filtration device includes a housing, within which two symmetrically arranged filtration mechanisms are installed. Each filtration mechanism includes an inlet pipe, an outer filter cylinder, a filter element, a first gate valve, and a second gate valve. The upper end of the outer filter cylinder has an inlet connector connected to the inlet pipe, allowing the inner cavity of the outer filter cylinder to communicate with the inside of the inlet pipe. The inlet end of the inlet pipe is connected to the first gate valve, and the other end is connected to the second gate valve. The inlet ends of the first gate valves in both filtration mechanisms are connected to a water supply pipe. The outer filter cylinder contains a filter element with a filter screen around its circumference for filtering impurities in the water. The filter element has a cylindrical structure, and a retaining ring is fixedly connected to the inner wall of the outer filter cylinder. The filter element passes through the retaining ring, and its outer wall seals against the retaining ring. The lower end of the outer filter cylinder is fixedly connected to an outlet connector. The outlet connectors of both filtration mechanisms are connected to the same manifold, which is connected to the upper end of a connecting pipe for discharging the filtered water. The first and second gate valves are used to control the flow of water through the pipeline.

[0008] Furthermore, an installation cylinder is fixedly connected to the inlet pipe. The installation cylinder is located between the second gate valve and the inlet connector. The inner cavity of the installation cylinder is connected to the inner cavity of the inlet pipe. A first rotating shaft is rotatably connected inside the installation cylinder. An actuating blade is fixedly connected to the outer wall of the first rotating shaft around its circumference. The actuating blade on one side of the first rotating shaft extends into the inlet pipe. The lower end of the first rotating shaft extends out of the installation cylinder and is sealed to it. A first bevel gear is fixedly connected to the lower end of the first rotating shaft. A filter outer cylinder is rotatably connected to its side wall. The second rotating shaft has one end extending to the outside of the filter outer cylinder and is fixedly connected to a second bevel gear. The second bevel gear meshes with the first bevel gear. An eccentric wheel is fixedly connected to one end of the second rotating shaft located in the inner cavity of the filter outer cylinder. The upper end of the filter element is provided with a flange. The eccentric wheel is located below the flange. The side of the eccentric wheel is attached to the flange and drives the flange to move up and down under the rotation of the second rotating shaft. A first compression spring is provided inside the filter outer cylinder. The lower end of the first compression spring abuts against the upper end of the flange of the filter element.

[0009] Furthermore, a drain pipe is connected to the side of the second gate valve away from the inlet connector, and the drain pipes on the two sets of filter mechanisms extend to the outside of the housing. These drain pipes are used to discharge cleaning wastewater to a designated area outside the housing. This ensures that wastewater is discharged to a designated area, preventing damage to the working environment of the site.

[0010] Furthermore, the buffer device includes a mounting base, a movable plate, a gate, and a second compression spring. The mounting base has a receiving cavity, in which a first receiving cavity and a second receiving cavity are perpendicular to each other. The upper end of the mounting base is connected to a connecting pipe, and the upper end of the first receiving cavity is connected to the inner cavity of the connecting pipe. The movable plate is slidably connected to the lower end of the first receiving cavity, and the upper end of the movable plate is flush with the bottom of the second receiving cavity. The periphery of the movable plate is sealed with the first receiving cavity. A sleeve is fixedly connected to the lower end of the movable plate, and a connecting rod is fixedly connected to the side wall of the sleeve. A pull rod is fixedly connected to the connecting rod. The pull rod passes through the second receiving cavity and is fixedly connected to the lower end of the gate. After the gate moves downward, it reduces the passage area of ​​the second receiving cavity. The sleeve contains a second compression spring, the lower end of which abuts against the bottom of the first receiving cavity. The end of the second receiving cavity away from the first receiving cavity is connected to a water supply pipe, allowing water in the second receiving cavity to flow into the water supply pipe.

[0011] Furthermore, a clamping cavity is formed on the upper side of the second receiving cavity, and the gate is located in the clamping cavity. This allows the gate to retract into the clamping cavity without affecting the water flow area of ​​the second receiving cavity.

[0012] Furthermore, the water replenishment pump is installed at the top of the water storage tank, which contains purified water, and the end of the water pump that is away from the water replenishment pump extends into the water storage tank and below the water surface.

[0013] Furthermore, the filter device is installed on the side wall of the water storage tank, and the buffer device is located below the filter device and installed on one side of the water storage tank.

[0014] The working principle of the above scheme is as follows: When the water level in the humidifier is lower than the set value, the water supply pump is turned on. The water supply pump draws water from the storage tank. The drawn water is filtered by the filter device and then passes through a buffer device. The pressure surge generated when the pump is turned on is buffered by the buffer device, allowing the water to flow smoothly into the humidifier. During normal filtration, the second gate valve of the two filter mechanisms is closed, and the first gate valve is opened, allowing the pumped water to enter the filter outer cylinder through the inlet pipe. The water flows through the filter element and then flows out through the outlet connector into the connecting pipe. When the filter element needs to be cleaned after a certain filtration time, the first gate valve of one of the filter mechanisms is closed. The valve closes and opens the second gate valve of the same group. Another set of filter mechanisms keeps the first gate valve open and the second gate valve closed, allowing pumped water to enter the filter mechanism with the first gate valve open through the inlet pipe for filtration. The filtered water enters the manifold, with a portion flowing into the connecting pipe. The remaining water from the manifold enters the filter mechanism with the second gate valve open through the lower outlet connector, rinsing the filter element inside. The rinsed wastewater flows from the inlet connector of this filter mechanism into the second gate valve and exits from the outlet of the gate valve, thus achieving the purpose of rinsing and cleaning the filter mechanism during use, ensuring its proper function. Keep the filter screen in normal use; perform the same cleaning operation on the other filter mechanism. After completion, restore the first and second gate valves to normal filtration status. During the flushing process of the valve core, as sewage flows out from the second gate valve, the water flows through the agitator blades located in the inlet pipe. The flowing water causes the agitator blades to rotate, which in turn causes the first shaft to rotate. Through gear transmission, the second shaft rotates, which in turn drives the eccentric wheel to rotate. This drives the flange to make the valve core vibrate up and down, so that while flushing the valve core filter screen, the valve core vibrates. This allows the impurities clogging the filter screen to be loosened and shaken off, accelerating the cleaning process. The speed of water flow increases, resulting in a cleaner cleaning and improved cleaning effect. When the water pressure suddenly increases at the start of water replenishment, the impacting water flows into the first receiving chamber. The water pressure impacts the movable plate, and the upper end of the movable plate moves downward under the sudden water pressure, thereby driving the pull rod to move downward, which in turn drives the gate to move downward. The downward movement of the gate reduces the cross-sectional area of ​​the water flow in the second receiving chamber, reducing the impact of the water flow on the equipment. After water is replenished for a period of time after the water flow is turned on, the internal water flow stabilizes. Under the action of the second compression spring, the movable plate resets, causing the gate to move upward, so that the second receiving chamber returns to its maximum passing area.

[0015] The present invention provides a water replenishment device for a carbon dioxide electrolysis humidifier, which has the following beneficial effects: when replenishing water, the water can be filtered by the filtration device, and the filtration mechanism can be cleaned by operating the first gate valve and the second gate valve during filtration, thereby achieving cleaning of the filtration mechanism in working state, thus avoiding clogging of the filtration device, and is easy to operate, avoiding downtime operation; and it buffers the water flow impact formed when it is turned on, ensuring stable operation of the equipment.

[0024] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should be noted that in the embodiments of the present invention, all directional indications (such as up-down-left-right-forward-backward...) are only used to explain the relative positional relationship and movement between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0027] like Figures 1-6 As shown, a water replenishment device for a carbon dioxide electrolysis humidifier includes a water storage tank 1, a water replenishment pump 2, a filter device 3, and a buffer device 4. A water pumping pipe 11 is installed on the water storage tank. The water pumping pipe 11 is connected to the inlet of the water replenishment pump 2. The outlet of the water replenishment pump 2 is connected to a water delivery pipe 21. The water delivery pipe 21 is connected to the filter device 3. The filter device 3 is used to filter the flowing water. The outlet of the filter device 3 is connected to a connecting pipe 5. The end of the connecting pipe 5 away from the filter device 3 is connected to the buffer device 4. The buffer device 4 is used to buffer the sudden increase in water pressure. The outlet of the buffer device 4 is connected to a water replenishment pipe 6. The water replenishment pipe 6 is connected to the water replenishment port of the humidifier to deliver water to the humidifier. Using the above technical solution, when the water level in the humidifier is lower than the set value, the water supply pump 2 is turned on. The water supply pump 2 draws water out of the water storage tank 1. The drawn water is filtered by the filter device 3 and then passes through the buffer device 4. The pressure impact formed when it is turned on is buffered by the buffer device 4, so that the water flow is smoothly replenished into the humidifier.

[0028] In this embodiment, the filtration device 3 includes a housing 31, within which two symmetrically arranged filtration mechanisms 7 are provided. Each filtration mechanism 7 includes an inlet pipe 71, an outer filter cylinder 72, a filter element 73, a first gate valve 74, and a second gate valve 75. The upper end of the outer filter cylinder 72 is provided with an inlet connector 76, which is connected to the inlet pipe 71, allowing communication between the inner cavity of the outer filter cylinder 72 and the inside of the inlet pipe 71. The inlet end of the inlet pipe 71 is connected to the first gate valve 74, and the other end of the inlet pipe 71 is connected to the second gate valve 75. The first gate valve 74 in the two sets of filtration mechanisms 7... The inlet end is connected to the water supply pipe 21; the filter outer cylinder 72 is equipped with a filter element 73, and the filter element 73 is surrounded by a filter screen for filtering impurities in the water. The filter element 73 has a cylindrical structure. A retaining ring 77 is fixedly connected to the inner wall of the filter outer cylinder 72. The filter element 73 passes through the retaining ring 77, and the outer wall of the filter element 73 is sealed to the retaining ring 77; the lower end of the filter outer cylinder 72 is fixedly connected to a water outlet connector 78. The water outlet connectors 78 of the two sets of filter mechanisms 7 are all connected to the same manifold 32. The manifold 32 is connected to the upper end of the connecting pipe 5 for discharging the water filtered by the filter mechanism 7. The first gate valve 74 and the second gate valve 75 are used to control the flow of water through the pipeline. During normal filtration, the second gate valve 75 of the two sets of filter mechanisms 7 is closed, and the first gate valve 74 is opened, allowing the pumped water to enter the outer filter cylinder 72 through the inlet pipe 71. The water flows through the filter element 73 and exits through the outlet connector 78 into the connecting pipe 5. When the filter element 73 of the filter mechanism 7 needs to be cleaned after a certain filtration time, the first gate valve 74 of one set of filter mechanisms 7 is closed and the second gate valve 75 of that set is opened. The other set of filter mechanisms 7 keeps the first gate valve 74 open and the second gate valve 75 closed, allowing the pumped water to enter the filter mechanism 7 with the first gate valve 74 open through the inlet pipe 71 for filtration. After filtration... Water flows into the manifold 32, a portion of which flows into the connecting pipe 5. Another portion of the water in the manifold 32 flows from the lower outlet connector 78 into the filter mechanism 7 opened by the second gate valve 75, rinsing the filter element 73 inside the filter mechanism 7. The rinsed wastewater flows from the inlet connector 76 of the filter mechanism 7 into the second gate valve 75 and is discharged from the outlet of the gate valve, thus achieving the rinsing and cleaning of the filter mechanism 7 during use and maintaining the normal use of the filter screen. The same cleaning operation is performed on the other filter mechanism 7. After completion, the first gate valve 74 and the second gate valve 75 are restored to normal filtration status.

[0029] In this embodiment, an installation cylinder 8 is fixedly connected to the water inlet pipe 71. The installation cylinder 8 is located between the second gate valve 75 and the water inlet connector 76. The inner cavity of the installation cylinder 8 is connected to the inner cavity of the water inlet pipe 71. A first rotating shaft 81 is rotatably connected to the installation cylinder 8. An actuating blade 82 is fixedly connected to the outer wall of the first rotating shaft 81. The actuating blade 82 on one side of the first rotating shaft 81 extends into the water inlet pipe 71. The lower end of the first rotating shaft 81 extends out of the installation cylinder 8 and the shaft body is sealed to the installation cylinder 8. A first bevel gear 83 is fixedly connected to the lower end of the first rotating shaft 81. A second rotating shaft 84 is rotatably connected to the side wall of the filter outer cylinder 72. One end of the second rotating shaft 84 extends to the outside of the filter outer cylinder 72 and is fixedly connected to a second bevel gear 85. The second bevel gear 85 meshes with the first bevel gear 83 through gear meshing. An eccentric wheel 86 is fixedly connected to one end of the second rotating shaft 84 located in the inner cavity of the filter outer cylinder 72. The upper end of the filter element 73 is provided with a flange 731. The eccentric wheel 86 is located below the flange 731. The side of the eccentric wheel 86 is attached to the flange 731 and drives the flange 731 to move up and down under the rotation of the second rotating shaft 84. A first compression spring 33 is provided inside the filter outer cylinder 72. The lower end of the first compression spring 33 abuts against the upper end of the flange 731 of the filter element 73. During the flushing process of the valve core, as sewage flows out from the second gate valve 75, the water flows through the agitator blade 82 located in the inlet pipe 71. The flowing water causes the agitator blade 82 to rotate, which in turn causes the first rotating shaft 81 to rotate. Through gear transmission, the second rotating shaft 84 rotates, which in turn drives the eccentric wheel 86 to rotate. This drives the flange 731 to make the valve core vibrate up and down. This vibration of the valve core, while flushing the valve core filter screen, causes the impurities clogging the filter screen to be loosened and shaken off, thus speeding up the cleaning process and making the cleaning more thorough, thereby improving the cleaning effect.

[0030] In this embodiment, the second gate valve 75 is connected to a drain pipe 34 on the side away from the inlet connector 76. The drain pipes 34 on the two sets of filter mechanisms 7 extend to the outside of the housing 31. The drain pipes 34 are used to discharge cleaning wastewater to a designated area outside the housing 31. This ensures that wastewater is discharged to a designated area, avoiding damage to the working environment of the place of use.

[0031] In this embodiment, the buffer device 4 includes a mounting base 41, a movable plate 42, a gate plate 43, and a second compression spring 44. The mounting base 41 has a receiving cavity, within which are a first receiving cavity 45 and a second receiving cavity 46 perpendicular to each other. The upper end of the mounting base 41 is connected to a connecting pipe 5, and the upper end of the first receiving cavity 45 communicates with the inner cavity of the connecting pipe 5. The movable plate 42 is slidably connected to the lower end of the first receiving cavity 45, and the upper end of the movable plate 42 is flush with the bottom of the second receiving cavity 46. The periphery of the movable plate 42 is sealed to the first receiving cavity 45. A sleeve 47 is fixedly connected to the lower end of 42. A connecting rod 48 is fixedly connected to the side wall of the sleeve 47. A pull rod 49 is fixedly connected to the connecting rod 48. The pull rod 49 passes through the second receiving cavity 46 and is fixedly connected to the lower end of the gate 43. After the gate 43 moves downward, it is used to reduce the passing area of ​​the second receiving cavity 46. A second compression spring 44 is provided inside the sleeve 47. The lower end of the second compression spring 44 abuts against the bottom of the first receiving cavity 45. The end of the second receiving cavity 46 away from the first receiving cavity 45 is connected to the water supply pipe 6 so that the water in the second receiving cavity 46 flows into the water supply pipe 6. When the water pressure suddenly increases, the impacting water flow enters the first receiving cavity 45. The water pressure impacts the movable plate 42, and the upper end of the movable plate 42 moves downward under the sudden action of water pressure, thereby driving the pull rod 49 to move downward, which in turn drives the gate plate 43 to move downward. The downward movement of the gate plate 43 reduces the cross-sectional area of ​​the water flow through the second receiving cavity 46, thereby reducing the impact of the water flow on the equipment. After the water flow is turned on and water is replenished for a period of time, the internal water flow reaches a stable state. Under the action of the second compression spring 44, the movable plate 42 is reset, thereby causing the gate plate 43 to move upward, so that the second receiving cavity 46 returns to the maximum passing area state.

[0032] In this embodiment, a clamping cavity is formed on the upper side of the second receiving cavity 46, and the gate 43 is located in the clamping cavity. This allows the gate 43 to retract into the clamping cavity without affecting the water flow area of ​​the second receiving cavity 46.

[0033] In this embodiment, the water replenishment pump 2 is installed at the upper end of the water storage tank 1, the water storage tank 1 stores pure water, and the end of the water pump 11 away from the water replenishment pump 2 extends into the water storage tank 1 and extends below the water surface.

[0034] In this embodiment, the filter device 3 is installed on the side wall of the water storage tank 1, and the buffer device 4 is located below the filter device 3 and installed on one side of the water storage tank 1.

[0035] The parts not covered in this technical solution are the same as or can be implemented using existing technologies.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
