Description

Technical Field

[0001] This utility model relates to the technical field of supporting devices for high-temperature co-electrolysis systems, and more specifically, to a quantitative evaporation device for water vapor in high-temperature co-electrolysis. Background Technology

[0002] High-temperature co-electrolysis (HTEE) is an energy conversion technology that converts water vapor and carbon dioxide into syngas (H2+CO) under high-temperature conditions. Due to its high thermoelectric efficiency and strong carbon conversion potential, it has broad application prospects in green hydrogen energy, fuel synthesis, and carbon recycling, and is particularly suitable for coupling with renewable energy sources such as wind power and photovoltaics to achieve electrochemical energy conversion and energy storage. This technology places stringent requirements on the water vapor supply system, requiring a stable temperature and controllable flow rate of water vapor, rapid response to system load changes to adapt to renewable energy fluctuations, and high-quality steam (to avoid liquid water impacting the fuel cell stack). Typically, supersaturated steam needs to be output to match the stack's operating conditions.

[0003] Currently, there are two main types of commonly used steam supply devices. The first is the industrial electric heating steam generator, which uses a water tank as a base and generates saturated or superheated steam through immersion heating elements. This type is suitable for scenarios with high tolerance for steam flow fluctuations. The second type is the quantitative steam supply type steam enhancement device. For example, some technical solutions use a combination of a micro-pump and an electric heating tube for heat conduction. The steam flow is controlled by adjusting the water supply rate and heating power. This type is suitable for miniaturized co-electrolysis or fuel cell systems.

[0004] Existing equipment has shortcomings in high-temperature co-electrolysis applications, such as a lack of precise control over the state of supersaturated steam. Utility Model Content

[0013] In some alternative embodiments, the secondary superheater is a stainless steel tube shell structure with a diameter smaller than that of the primary evaporator, and a second electric heating element is wound around the outer wall of the secondary superheater, the second electric heating element being electrically connected to the controller.

[0014] In some optional embodiments, the second electric heating element of the secondary superheater is connected to the controller via an independent control circuit, which is independent of the control circuit of the first electric heating element of the primary evaporator, so as to realize that the heating power of the second electric heating element is independently regulated from the heating power of the first electric heating element.

[0015] In some alternative implementations, the pipe between the primary evaporator and the secondary superheater is a thermally insulated metal pipe.

[0018] The technical solution of this application has the following technical effects, as detailed below:

[0019] In this application's technical solution, an electronic water pump delivers water from the tank to the common rail chamber. A first pressure sensor monitors the chamber pressure in real time and adjusts the pump speed via feedback from the controller, ensuring stable water supply pressure. Liquid water in the common rail chamber is atomized by several high-frequency electronically controlled atomizing nozzles and then horizontally sprayed into the primary evaporator chamber. The controller can accurately control the atomized water volume by adjusting the nozzle's pulse signal, achieving quantitative and precise control of the water supply. The primary evaporator performs preliminary heating and evaporation of the atomized water. A first temperature sensor installed on its chamber wall monitors the evaporation temperature and feeds it back to the controller. The controller, through coordinated adjustment of the water supply and heating power, can stably generate saturated steam. The generated saturated steam further enters the secondary superheater for heating and quality improvement. The second temperature sensor, dew point temperature sensor, and second pressure sensor arranged in the outlet pipe of the secondary superheater can monitor the temperature, dryness, and pressure parameters of the superheated steam in real time, and transmit the data synchronously to the controller. After comprehensively analyzing multiple parameters, the controller can dynamically adjust the water spray volume or heating power of the atomizing nozzle in reverse, and finally output superheated steam with stable temperature, high dryness, and suitable pressure to meet the steam quality requirements of the high-temperature co-electrolysis system.

[0027] Figure 1 This is a schematic diagram of the overall structure of the high-temperature co-electrolysis water vapor quantitative evaporation device provided in this application. The following is a combined view... Figure 1 The technical solution of this utility model will be described. For example... Figure 1As shown, the evaporation device may include a water tank 1, an electric water pump 2, a primary evaporator 4, a secondary superheater 5, a common rail chamber 7, and a controller. The outlet of the water tank 1 is connected to the inlet of the electric water pump 2 via a pipe. The outlet of the electric water pump 2 is connected to the inlet of the common rail chamber 7 via a pipe. The common rail chamber 7 is connected to several high-frequency electrically controlled atomizing nozzles 3 via pipes. The nozzle of each high-frequency electrically controlled atomizing nozzle 3 extends laterally into the cavity of the primary evaporator 4. A first pressure sensor 8 is installed at the lateral interface of the common rail chamber 7, and a first temperature sensor 9 is installed on the outer surface of the side wall of the primary evaporator 4. The outlet of the primary evaporator 4 is connected to the inlet of the secondary superheater 5 via a pipe. The outlet of the secondary superheater 5 is used to output superheated steam. A second temperature sensor 10, a dew point temperature sensor 11, and a second pressure sensor 12 are sequentially installed on the outer surface of the side wall of the outlet pipe of the secondary superheater 5. The controller is electrically connected to the electronic water pump 2, the high-frequency electronically controlled atomizing nozzle 3, the first pressure sensor 8, the first temperature sensor 9, the second temperature sensor 10, the dew point temperature sensor 11, and the second pressure sensor 12, respectively.

[0028] The working principle of the high-temperature co-electrolysis water vapor quantitative evaporation device described in the previous section is explained in detail below. In this device, water tank 1 is used to store liquid water, which is pumped by electronic water pump 2 and transported to common rail chamber 7 through pipeline. Since a first pressure sensor 8 is installed at the side interface of common rail chamber 7, it can collect the water pressure signal in the chamber in real time. After the controller obtains the water pressure signal, it can dynamically adjust the speed or start and stop of electronic water pump 2 according to the preset pressure threshold, thereby stabilizing the water pressure in common rail chamber 7. Figure 1 As shown, the common rail chamber 7 is connected to several high-frequency electrically controlled atomizing nozzles 3 via pipes. These nozzles can receive electrical signals from the controller, such as pulse width modulation signals. The controller can then precisely control the amount of atomized water injected into the primary evaporator 4 chamber in a single or continuous manner by controlling the nozzle's energizing time. Each nozzle 3 extends laterally into the primary evaporator 4 chamber, allowing the atomized water to directly contact the heating environment within the primary evaporator 4, thereby accelerating the evaporation process.

[0029] Then, the evaporation phase change stage begins. The first-stage evaporator 4 heats the mist water injected through the nozzle 3, causing the mist water to evaporate rapidly into saturated steam. The first temperature sensor 9, installed on the outer surface of the side wall of the first-stage evaporator 4, can monitor the temperature inside the chamber in real time (this temperature reflects the evaporation efficiency and the state of saturated steam). The controller collects this signal, and if the temperature deviates from the preset range, the controller can coordinate to adjust the water supply of the electronic water pump, indirectly regulating the evaporation load, thereby ensuring the stable generation of saturated steam.

[0030] Then, the superheating and upgrading stage begins. The saturated steam output from the primary evaporator 4 is piped to the secondary superheater 5 for further heating into superheated steam. To stabilize the quality of the generated superheated steam, this invention includes a second temperature sensor 10, a dew point temperature sensor 11, and a second pressure sensor 12 sequentially installed on the outer surface of the outlet pipe of the secondary superheater 5. The second temperature sensor 10 monitors the temperature of the steam at the outlet of the secondary superheater 5, determining whether a superheated state has been reached (i.e., the temperature must be higher than the saturation temperature at the corresponding pressure). The dew point temperature sensor 11 detects the steam dew point temperature, which indirectly reflects the steam dryness. The second pressure sensor 12 collects the steam pressure and, in conjunction with the second temperature sensor 10, verifies whether the steam thermodynamic parameters meet the requirements of the co-electrolysis system. The signals collected by these three sensors are synchronously transmitted to the controller. After comprehensive analysis, the controller adjusts the water spray volume of the high-frequency electronically controlled atomizing nozzle 3 in reverse. If the dryness is too low, the water spray is reduced, lowering the droplet evaporation load of the secondary superheater 5, thus ensuring stable superheated steam temperature, meeting dryness standards, and appropriate pressure.

[0031] During operation, the device uses the controller as the core hub, and all components work together to achieve closed-loop control of the entire process, thereby ensuring steam quality. The controller receives monitoring signals from the first pressure sensor 8, the first temperature sensor 9, the second temperature sensor 10, the dew point temperature sensor 11, and the second pressure sensor 12 in real time, and dynamically adjusts the water supply of the electronic water pump 2 and the water spray volume of the high-frequency electronically controlled atomizing nozzle 3. If the pressure of the common rail chamber 7 is abnormal, the electronic water pump is adjusted to stabilize the liquid supply. If the temperature of the first-stage evaporator 4 is abnormal, the water spray volume is adjusted to balance the evaporation load. If the outlet parameters of the second-stage superheater 5 are abnormal, the water spray volume is adjusted to meet the superheating and quality improvement requirements.

[0032] In this application's technical solution, an electronic water pump delivers water from the tank to the common rail chamber. A first pressure sensor monitors the chamber pressure in real time and adjusts the pump speed via feedback from the controller, ensuring stable water supply pressure. Liquid water in the common rail chamber is atomized by several high-frequency electronically controlled atomizing nozzles and then horizontally sprayed into the primary evaporator chamber. The controller can accurately control the atomized water volume by adjusting the nozzle's pulse signal, achieving quantitative and precise control of the water supply. The primary evaporator performs preliminary heating and evaporation of the atomized water. A first temperature sensor installed on its chamber wall monitors the evaporation temperature and feeds it back to the controller. The controller, through coordinated adjustment of the water supply and heating power, can stably generate saturated steam. The generated saturated steam further enters the secondary superheater for heating and quality improvement. The second temperature sensor, dew point temperature sensor, and second pressure sensor arranged in the outlet pipe of the secondary superheater can monitor the temperature, dryness, and pressure parameters of the superheated steam in real time, and transmit the data synchronously to the controller. After comprehensively analyzing multiple parameters, the controller can dynamically adjust the water spray volume or heating power of the atomizing nozzle in reverse, and finally output superheated steam with stable temperature, high dryness, and suitable pressure to meet the steam quality requirements of the high-temperature co-electrolysis system.

[0033] Based on the technical solutions described above, this application also provides some further technical solutions, which are described below.

[0034] In an optional embodiment, the first-stage evaporator 4 is a horizontal cylindrical shell structure with a first electric heating element wound around its inner wall, and the shell of the first-stage evaporator 4 may be covered with a heat insulation layer; wherein, the first electric heating element is electrically connected to the controller.

[0035] In this embodiment, the primary evaporator 4 is designed as a horizontal cylindrical shell structure, with a first electric heating element wound around its inner wall to provide heat energy to the cavity of the primary evaporator 4. Combined with the atomized water sprayed by the high-frequency electrically controlled atomizing nozzle 3, the atomized water can be converted into saturated steam through evaporation. Simultaneously, the shell of the primary evaporator 4 is covered with a heat insulation layer, which reduces heat transfer from the cavity of the primary evaporator 4 to the outside, preventing heat loss and helping to maintain the temperature environment required for evaporation within the cavity. Furthermore, the first electric heating element is electrically connected to a controller, allowing the controller to adjust the heating power of the first electric heating element based on the temperature of the outer surface of the side wall of the primary evaporator 4 cavity monitored by the first temperature sensor 9, ensuring the stable evaporation of the atomized water into saturated steam.

[0036] In an optional embodiment, a plurality of high-frequency electronically controlled atomizing nozzles 3 can be arranged at equal intervals along the axial direction of the horizontal cylindrical shell perpendicular to the first-stage evaporator 4, with the distance between two adjacent high-frequency electronically controlled atomizing nozzles 3 being 15cm-25cm.

[0037] In an optional embodiment, the secondary superheater 5 can be a stainless steel tube shell structure with a diameter smaller than that of the primary evaporator 4. A second electric heating element is wound around the outer wall of the secondary superheater 5, and the second electric heating element is electrically connected to the controller.

[0038] In this embodiment, the secondary superheater 5 adopts a stainless steel shell and tube structure because stainless steel possesses excellent high-temperature and high-pressure resistance, enabling it to stably adapt to the operating environment of superheated steam. Simultaneously, the diameter of the secondary superheater 5 is designed to be smaller than that of the primary evaporator 4. This increases the steam flow velocity inside the secondary superheater 5, allowing for more thorough contact between the steam and the inner wall of the shell and tube, creating more efficient heat exchange conditions for the subsequent superheating process. A second electric heating element is wound around the outer wall of the secondary superheater 5. This electric heating element, arranged in a wound manner, evenly covers the outer wall of the shell and tube, ensuring that the saturated steam inside the secondary superheater 5 can absorb heat from all directions, thereby achieving the temperature conversion from saturated steam to superheated steam.

[0039] Simultaneously, the second electric heating element is electrically connected to the controller. The controller can dynamically adjust the heating power of the second electric heating element based on signals from the second temperature sensor 10, dew point temperature sensor 11, and second pressure sensor 12 on the outlet pipe of the secondary superheater 5. Specifically, if the second temperature sensor 10 detects that the steam temperature has not reached the preset superheat temperature, or the dew point temperature sensor 11 detects that the difference between the steam dew point and temperature is too small (indirectly reflecting insufficient steam dryness and a high concentration of liquid droplets), the controller can increase the power of the second electric heating element to enhance the heating effect. If the steam temperature is too high or the dryness is excessive, the heating power can be reduced. Through this closed-loop control logic, the temperature, dryness, and pressure of the superheated steam can be precisely controlled to meet the input requirements of the high-temperature co-electrolysis system.

[0040] In an optional embodiment, the second electric heating component of the secondary superheater 5 is connected to the controller via an independent control circuit. This independent control circuit is independent of the control circuit of the first electric heating component of the primary evaporator 4, so that the heating power of the second electric heating component can be adjusted independently of the heating power of the first electric heating component.

[0041] In this embodiment, the second electric heating element of the secondary superheater 5 is connected to the controller via an independent control circuit. This circuit is independent of the control circuit of the first electric heating element of the primary evaporator 4 at the hardware level, so that the heating power of the second electric heating element and the first electric heating element can be independently controlled without interference. The following is a detailed description... Figure 1 The design concept of this scheme will be explained.

[0042] From a functional perspective, the first electric heating component of the primary evaporator 4 in this application is responsible for providing heat energy for the evaporation process of converting mist water into saturated steam. Its power needs to be flexibly adjusted according to the cavity temperature monitored by the first temperature sensor 9, in conjunction with the changes in the water spray volume of the high-frequency electrically controlled atomizing nozzle 3. For example, when the water spray volume increases, the heating power needs to be increased to avoid a decrease in evaporation efficiency. The second electric heating component of the secondary superheater 5 is responsible for superheating the conversion of saturated steam into superheated steam. Its power needs to be dynamically corrected based on the steam parameters (whether the temperature meets the standard, whether the dryness meets the requirements, and whether the pressure matches) fed back by the second temperature sensor 10, the dew point temperature sensor 11, and the second pressure sensor 12. For example, when the steam temperature is too low, the power needs to be increased to achieve superheating and quality improvement. Therefore, in the technical solution of this embodiment, when the control circuits of the two are independent, the controller can adjust the power of the second electric heating component. If the power is increased due to insufficient secondary steam temperature, it will not affect the heating state of the primary evaporator through circuit coupling, thus avoiding unexpected fluctuations in the cavity temperature of the primary evaporator. Conversely, when the power of the first electric heating component in the first-stage evaporator is adjusted due to changes in the water spray volume, it will not interfere with the heating regulation of the second-stage superheater so that the second-stage superheater can achieve the goal of precise superheating of saturated steam and will not be affected by power fluctuations during the evaporation stage.

[0043] In an optional embodiment, the pipe between the primary evaporator 4 and the secondary superheater 5 is a thermally insulated metal pipe.

[0044] In the optional embodiment, a pressure relief valve 6 is also included. The inlet of the pressure relief valve 6 is connected to the common rail cavity 7 through a pipe, and the outlet of the pressure relief valve 6 is connected to the water tank 1 through a pipe. The pressure relief valve 6 is an electrically controlled pressure relief valve, and the pressure relief valve 6 is electrically connected to the controller.

[0045] In this embodiment, the pressure relief valve 6 is an electrically controlled type and is electrically connected to the controller. Therefore, when the first pressure sensor 8 at the side interface of the common rail chamber 7 detects that the pressure inside the chamber exceeds a preset safety threshold—for example, when the electronic water pump 2 experiences abnormal overclocking leading to a sudden increase in supply pressure, or when the high-frequency electrically controlled atomizing nozzle 3 becomes suddenly blocked, obstructing pressure relief in the common rail chamber—the controller sends an electrical signal to the pressure relief valve 6, driving it to open. At this time, the high-pressure liquid water in the common rail chamber flows back to the water tank 1 along the pipeline, quickly reducing the pressure in the common rail chamber and preventing damage to the common rail chamber, connecting pipes, or nozzles due to pressure overload. Once the pressure in the common rail chamber returns to the normal range, the controller sends a signal again to close the pressure relief valve 6, terminating the backflow.

[0046] In an optional embodiment, the inner wall of the water tank 1 is coated with a corrosion-resistant epoxy resin, and the top of the water tank 1 is also provided with a vent with a filter screen.

[0047] In this embodiment, the inner wall of the water tank 1 is coated with a corrosion-resistant epoxy resin coating. This coating effectively prevents metal corrosion caused by long-term immersion in water, thus preventing rust from falling off and contaminating the water inside the tank. This ensures that the water entering the electronic water pump 2 and the high-frequency electronically controlled atomizing nozzle 3 remains clean and free of impurities, preventing blockages in subsequent pipelines due to impurity accumulation or damage to components due to water corrosion. Simultaneously, the top of the water tank 1 is equipped with a vent with a filter screen. This vent is used to balance the air pressure inside and outside the tank. When the electronic water pump 2 draws water from the tank, the internal pressure decreases, allowing outside air to enter smoothly through the vent, preventing negative pressure from hindering normal water flow. The filter screen also filters dust, particles, and other impurities from the air, preventing them from entering the water tank 1 and contaminating the water.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
