Technical Field

[0001] This utility model belongs to the field of high-pressure gas technology, and more specifically, it relates to a device for rapidly vaporizing and energizing liquid gas. Background Technology

[0002] The technology of using gas to power water jets requires sufficiently high gas pressure and a sufficiently continuous gas supply. Using air compressors to generate compressed air for water jetting is limited by factors such as pressure and energy consumption, thus hindering technological development.

With the development of the battery industry, especially the electric vehicle industry, how to quickly achieve energy conversion and rapidly energize liquid gas to realize the transition from liquid to gas in a short time, while maintaining high efficiency and meeting requirements for the temperature and pressure of the discharged gas, is currently an area that needs to be addressed and improved.

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please see Figure 1 and Figure 2 The present invention provides a device for rapid vaporization and energizing of liquid gas. The device includes: a liquid storage tank 1, a phase change tank 2, a heating tank 3, and a gas tank 4. The liquid storage tank 1 stores liquid gas. The phase change tank 2 is connected to the liquid storage tank 1 via an injection valve 6; a phase change heating rod 8 is installed inside the phase change tank 2. The heating tank 3 is connected to the phase change tank 2. The gas tank 4 is connected to the heating tank 3 via an outlet valve 7. The injection valve 6 and the outlet valve 7 are used to control the flow direction of the liquid gas and the vaporized gas, respectively.

[0027] The beneficial effects of the liquid gas rapid vaporization and energy-generating device provided by this utility model are as follows: Compared with the prior art, in this utility model, the liquid gas is stored in a storage tank 1, and a phase change tank 2 is connected to the storage tank 1 through a liquid injection valve 6. A heating rod 8 is installed in the phase change tank 2, and a heating tank 3 is connected to the phase change tank 2. A gas tank 4 is connected to the heating tank 3 through a gas outlet valve 7.

[0028] In practical applications, after the injection valve 6 is opened, the liquid gas enters the phase change tank 2 from the storage tank 1. The phase change is achieved by the heating rod 8 inside the phase change tank 2, and the gas then vaporizes. The vaporized gas enters the heating tank 3, and after heating, it enters the gas tank 4 for further processing and use. The structure of this application is relatively simple, enabling continuous and cyclical phase change processing of suitable gases. The short gas processing time can meet the gas requirements of special scenarios.

[0029] This device can quickly provide large-scale high-pressure gas at any pressure and temperature. It utilizes electrical energy to rapidly vaporize liquid carbon dioxide and liquid nitrogen, achieving high energy efficiency in the vaporization process. The device is simple in structure, safe, reliable, and easy to automate, avoiding many problems associated with traditional high-pressure pumps and vaporization vessels operating under low-temperature and high-pressure conditions. This application can be used in high-rise fire suppression systems (up to 100 meters high). Liquid carbon dioxide is injected into the phase change tank 2; after injection, the valve is closed to achieve pressure isolation from the storage tank 1.

[0030] In some embodiments of the liquid gas rapid vaporization energy-generating device provided in this application, please refer to... Figure 1 and Figure 2 The heating rod 8 is installed along the length of the phase change tank 2. All parts work in coordination to generate the necessary high-pressure gas conditions for work. The electric heating rod 8 in the phase change tank 2 is located in liquid carbon dioxide. After opening the outlet valve 7, it is energized, causing localized vaporization of the carbon dioxide. The lower-temperature gas then enters the heating tank 3. The phase change tank 2 contains the electric heating rod 8, a device that rapidly vaporizes liquid carbon dioxide through electric heating. The high-pressure gas generated by this device is ultimately stored in the high-pressure gas tank 4 for later use.

[0031] The heating tank 3 further heats the gas entering it, ensuring that the gas temperature and pressure reach suitable values ​​to meet the requirements for performing work. The high-pressure gas tank 4 serves to store the final required high-pressure gas throughout the process; it can be retrieved from the high-pressure gas tank 4 when needed for work. Through precise coordination between its components, the entire device can efficiently and stably generate high-pressure gas that meets the needs of various working scenarios, providing strong support for subsequent work using high-pressure gas. It is widely used in industrial production, scientific research experiments, and many other fields, greatly improving production efficiency and experimental accuracy, and promoting technological progress and development in related industries.

[0032] In some embodiments of the liquid gas rapid vaporization energy-generating device provided in this application, please refer to... Figure 1 and Figure 2 The phase change tank 2 is equipped with a pressure sensor 13, a level gauge 12, and an exhaust valve 14. A portion of liquid carbon dioxide is taken from the storage tank 1 and stored in the high-pressure phase change tank 2. After closing the injection valve 6 and opening the exhaust valve 7, the liquid carbon dioxide is gradually vaporized by electric heating, and the final gas is transported to the high-pressure gas tank 4 for later use. After the process is complete, the exhaust valve 7 is closed, the exhaust valve 14 is opened, and the pressure is released. Liquid is then injected into the phase change tank 2 again, and the above process is repeated. During the injection process, the pressure in the gas tank 4 gradually increases to the required pressure, and the energizing process is complete.

[0033] The device is also equipped with a level gauge 12 to display the liquid carbon dioxide level and provide the controller 5 with the opening and closing signals for the injection valve 6. A pressure transmitter is installed to display pressure changes in the phase change tank 2, the liquid storage tank 1, and the gas tank 4. An exhaust valve 14 is installed to release residual gas in the phase change tank 2, facilitating the injection of liquid into the phase change tank 2. A rupture disc 11 is installed to prevent danger caused by excessive pressure inside the phase change tank 2 due to misoperation.

[0034] In practical applications, the accurate display of the level gauge 12 is crucial for controlling the injection volume. When the level gauge 12 detects that the liquid carbon dioxide level in the phase change tank 2 has reached the set upper limit, it will promptly transmit a signal to the controller 5. Upon receiving the signal, the controller 5 will quickly close the injection valve 6 to prevent excessive injection of liquid carbon dioxide. Conversely, when the level falls below the set lower limit, the controller 5 will be triggered to open the injection valve 6, ensuring that there is sufficient liquid carbon dioxide in the phase change tank 2 for the vaporization process.

[0035] The pressure transmitter can monitor pressure changes in key components such as phase change tank 2, liquid storage tank 1, and gas tank 4 in real time. If an abnormal pressure fluctuation is detected in any component—for example, excessively high pressure in gas tank 4 may affect the safety of subsequent use, or excessively low pressure in liquid storage tank 1 may lead to insufficient liquid carbon dioxide supply—the pressure transmitter will immediately report this situation to the controller 5. The controller 5 will then make corresponding adjustments according to a preset program, such as adjusting the opening of the gas outlet valve 7 or the liquid injection valve 6, to maintain stable pressure in each component.

[0036] The exhaust valve 14 plays a crucial role in the operation of the device. After each vaporization process, closing the outlet valve 7 and opening the exhaust valve 14 effectively releases the residual gas in the phase change tank 2. This timely removal of residual gas creates favorable conditions for the subsequent injection of liquid into the phase change tank 2. Excessive residual gas in the phase change tank 2 would occupy space, affecting the injection volume of liquid carbon dioxide and the vaporization effect. Proper operation of the exhaust valve 14 ensures smooth liquid injection each time, guaranteeing the stability and efficiency of the device operation.

[0037] The rupture disc 11 plays an indispensable role as a safety guarantee for the unit. During operation, in the event of operator error causing a rapid increase in pressure within the phase change tank 2, exceeding its withstand limit, the rupture disc 11 will rupture instantly. This timely release of excessive pressure within the tank prevents explosions and other dangerous situations, thus protecting the entire unit and the surrounding environment. During routine maintenance and repairs, the condition of the rupture disc 11 should be checked periodically to ensure it functions correctly in critical situations.

[0038] In some embodiments of the liquid gas rapid vaporization energy-generating device provided in this application, please refer to... Figure 1 and Figure 2 A rupture disc 11 is installed on the side wall of the phase change tank 2. A portion of liquid carbon dioxide is taken out from the storage tank 1 and stored in the high-pressure resistant phase change tank 2. The phase change tank 2 is made of low-temperature resistant stainless steel, and its volume is designed according to the amount used per cycle.

[0039] The phase change heating rod 8 inside the phase change tank 2 starts working, heating the liquid carbon dioxide and causing it to gradually undergo a phase change. As the temperature rises, the liquid carbon dioxide slowly vaporizes, and the vaporized carbon dioxide gas enters the heating tank 3 through a pipe connected to the phase change tank 2. The heating tank 3 is equipped with a special heating structure that can further heat the vaporized carbon dioxide. After being heated by the heating tank 3, the carbon dioxide gas flows to the gas tank 4 for storage through the outlet valve 7. Throughout the process, the liquid injection valve 6 strictly controls the flow rate of liquid carbon dioxide from the storage tank 1 into the phase change tank 2, while the outlet valve 7 precisely controls the flow rate of vaporized carbon dioxide gas from the heating tank 3 into the gas tank 4, ensuring the stable operation of the device. When the pressure inside the phase change tank 2 is too high, the rupture disc 11 installed on the side wall provides safety protection, preventing the tank from becoming dangerous due to excessive pressure. After the gas tank 4 is filled with a certain amount of vaporized carbon dioxide, it can be transported to the corresponding application scenario according to actual needs, realizing the rapid vaporization of carbon dioxide for electro-energization applications.

[0040] In some embodiments of the liquid gas rapid vaporization energy-generating device provided in this application, please refer to... Figure 1 and Figure 2 Temperature detectors are installed at the gas outlet 15 of both the phase change tank 2 and the heating tank 3. These detectors display the temperature changes at gas outlet 15. The outlet temperature is set, and the heating current is controlled by the temperature readings from the detectors.

[0041] When the outlet gas temperature exceeds the set value, the heating current is reduced to slow down the vaporization process within the phase change tank 2, thus reducing the amount of vaporized gas produced. When the outlet gas temperature falls below the set value, the heating current is increased to accelerate the vaporization rate and increase the output of vaporized gas. This precise temperature control ensures rapid, stable, and demand-compliant vaporization of carbon dioxide, guaranteeing the efficient operation of the device. Simultaneously, real-time data from the temperature detectors is fed back to the control system, allowing operators to monitor the device's operating status, promptly identify potential anomalies, and make adjustments, further improving the device's reliability and stability and providing strong support for the rapid vaporization and electrification of carbon dioxide.

[0042] In some embodiments of the liquid gas rapid vaporization energy-generating device provided in this application, please refer to... Figure 1 The heating tank 3 is equipped with a heating rod 9. The vaporized gas is heated to the required temperature by the heating rod 9 in the heating tank 3, and then injected into the gas tank 4 for later use. The gas in the heating tank 3 is heated to the set temperature by the heating rod 9 and then enters the gas tank 4.

[0043] The vaporized, heated gas stored in gas tank 4 can be transported to the appropriate application scenario according to actual needs. During the transportation process, a flow rate regulating valve can be set to precisely control the gas output flow rate, ensuring that the gas can stably and accurately meet the usage requirements. For example, when this device is applied to certain stages of industrial production, these specially treated heated gases can participate in specific chemical reactions or processes, playing a unique role. Moreover, to ensure the safety and stability of the entire device, monitoring equipment such as pressure sensor 13 and temperature sensor 10 can be equipped to monitor parameters such as gas pressure and temperature in gas tank 4 in real time. Once an abnormality is detected, an alarm can be issued in a timely manner and corresponding measures can be taken, such as automatically adjusting the valve opening and starting the cooling system, to avoid potential safety accidents and ensure the normal operation and use of the device.

[0044] In some embodiments of the liquid gas rapid vaporization energy-generating device provided in this application, please refer to... Figure 1 A temperature sensor 10 connects the heating tank 3 and the gas tank 4. After all the liquid carbon dioxide in the phase change tank 2 has vaporized, the outlet valve 7 is closed and the exhaust valve 14 is opened to release the pressure of the phase change tank 2 to 1.0 MPa. Then, the injection valve 6 is opened to inject the low-temperature liquid carbon dioxide from the storage tank 1 into the phase change tank 2. The liquid level gauge 12 determines that the injection is complete. Then, the injection valve 6 and the exhaust valve 14 are closed, the outlet valve 7 is opened, and heating and vaporization are started again. The above process is repeated until the pressure of the gas tank 4 reaches the required level.

[0045] During the aforementioned cyclic operation, temperature sensor 10 monitors the temperature between heating tank 3 and gas tank 4 in real time and transmits the data to the control system. The control system automatically adjusts the power of the phase change heating rod 8 according to the preset temperature range to ensure the stability and efficiency of the vaporization process. When the pressure in gas tank 4 approaches the usage requirements, the control system gradually reduces the power of the phase change heating rod 8 to prevent excessive pressure rise. Simultaneously, level gauge 12 continuously monitors the liquid levels in storage tank 1 and phase change tank 2. If the liquid level in storage tank 1 is too low, an alarm will sound to remind the operator to replenish liquid carbon dioxide in a timely manner. Under precise control, the entire device stably performs the carbon dioxide vaporization process, providing a stable and reliable supply of vaporized gas for subsequent use.

[0046] In some embodiments of the liquid gas rapid vaporization energy-generating device provided in this application, please refer to... Figure 1 and Figure 2 The liquid injection valve 6, heating rod 8, heating rod 9, temperature sensor 10, and gas outlet valve 7 are all electrically connected to the controller 5. Apart from the opening and closing of the valves, the device has no other working mechanical devices, is not limited by the power of mechanical devices, and can have a high power vaporization speed. It can be expanded to form a large-scale device by increasing the system scale or by connecting units in series or parallel.

[0047] When vaporization of liquefied gas is required, controller 5 first controls the injection valve 6 to open, allowing liquefied gas to flow from storage tank 1 into phase change tank 2 via injection valve 6. Phase change heating rod 8 then activates, heating the liquefied gas in phase change tank 2 and causing it to change phase to gas. Temperature sensor 10 monitors the temperature inside phase change tank 2 in real time. When the temperature reaches the set value, controller 5 controls the opening of the connecting valve between heating tank 3 and phase change tank 2, allowing the vaporized gas to enter heating tank 3. Inside heating tank 3, the gas is further heated to meet subsequent usage requirements. The heated gas from heating tank 3 flows out through outlet valve 7, supplying equipment that needs to use the vaporized gas. In this way, the entire rapid vaporization and energy-generating device for liquefied gas can efficiently and stably achieve rapid vaporization of liquefied gas and deliver the vaporized gas to where it is needed. Meanwhile, since the device is not limited by the power of mechanical devices, by increasing the system scale or connecting units in series or parallel, large-scale devices can be formed according to actual needs to meet the demand for large amounts of gasified gas in different scenarios, providing reliable gas supply solutions for industrial production, energy utilization and other fields.

[0048] In some embodiments of the liquid gas rapid vaporization energy-generating device provided in this application, please refer to... Figure 1 The controller 5 is a PLC controller. The PLC controller 5 is electrically connected to the phase change heating rod 8 and is used to control the working state of the phase change heating rod 8 to achieve precise control of the heating phase change process of the liquid gas in the phase change tank 2. Simultaneously, the PLC controller 5 is also signal-connected to the injection valve 6 and the outlet valve 7, adjusting the valve opening in real time according to parameters such as pressure and temperature within the device to ensure that the injection volume of liquid gas and the discharge volume of vaporized gas are at their optimal levels, thereby ensuring the stable and efficient operation of the entire liquid gas rapid vaporization energy-generating device. During device operation, when the liquid carbon dioxide in the storage tank 1 reaches a certain amount, the PLC controller 5 controls the injection valve 6 to open, allowing an appropriate amount of liquid carbon dioxide to flow into the phase change tank 2. Under the instruction of the PLC controller 5, the phase change heating rod 8 begins to work, gradually increasing the temperature according to the preset heating program, causing the liquid carbon dioxide in the phase change tank 2 to rapidly vaporize into a gaseous state. The increased pressure of the vaporized carbon dioxide gas pushes the gas flow towards the heating tank 3. At this time, based on the information fed back by the temperature sensor 10 inside the heating tank 3, the PLC controller 5 adjusts the opening of the outlet valve 7 in a timely manner, delivering the vaporized carbon dioxide gas at the appropriate temperature to the required location, thus realizing the rapid vaporization and electro-energization function of carbon dioxide. Furthermore, the PLC controller 5 has data recording and analysis functions, capable of recording various parameters during the device's operation, such as temperature, pressure, and flow rate, and analyzing this data to promptly identify potential problems during device operation, taking preventative and handling measures in advance, and further improving the reliability and stability of the device.

[0049] Controller 5. Using pressure and temperature as control signals, it controls the automated process. Controller 5 employs PLC technology to achieve automated system operation.

[0050] By electrically controlling the gas-liquid phase change, high-pressure gas of any pressure value can be supplied, greatly supporting pneumatic applications. Using electricity to achieve gas-liquid phase change has many advantages over fuel combustion. It eliminates the need for heat exchangers and flow rate regulation, making it more energy-efficient and environmentally friendly, easier to control, and easier to automate and intelligently implement.

[0051] The energy efficiency and other indicators generated by phase change have been significantly improved and optimized; the pressure adjustment range has been greatly expanded, no longer limited by the pressure resistance of the liquid storage container, and can be set as needed; as long as there is enough electricity, the scale can be large enough, which is extremely important in certain fields. For example, in water cannon spraying, the greater the pressure and the larger the volume, the farther the spray can reach. In the experimental phase, water cannon spraying at a distance of 180 meters has been achieved.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
