Description

Technical Field

[0001] The utility model relates to the technical field of industrial gas filling, in particular to a gas distribution device for vaporizing liquefied gas by using solar energy. Background Technique

[0002] At present, most gas filling stations still use carbon dioxide gas cylinders to fill the mixed gas (carbon dioxide + argon). Carbon dioxide gas belongs to high-pressure liquefied gas, and its critical temperature is 31°C. When the temperature is lower than 31°C, it can be liquefied by pressurization. Therefore, the actual state of carbon dioxide during filling cannot be controlled, resulting in low accuracy of the mixed gas. During the filling process of carbon dioxide, the gas remaining in the pipeline will affect the purity of carbon dioxide after filling, making it impossible to meet the requirements of high purity. In addition, some gas filling stations use the gas-phase pipeline of carbon dioxide storage tanks to fill the mixed gas. However, the working pressure of carbon dioxide storage tanks on the market is generally 2.1 MPa, and there is no pressurization device for carbon dioxide storage tanks. This method can only fill the mixed gas with a low carbon dioxide content, and due to the low gas source pressure, the filling efficiency cannot meet the production requirements. To solve these problems, it is necessary to further improve and optimize the existing technology to improve the efficiency and accuracy of gas filling. Content of the Utility Model

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] Please refer to Figure 1, the utility model provides a technical solution: a gas distribution device for vaporizing liquefied gas using solar energy, including: a first storage tank 1, a second storage tank 2, a water bath bucket 3, a heating mechanism 4, a vaporizer 5 and a collection mechanism. The first storage tank 1 and the second storage tank 2 are used to provide gas; the water bath bucket 3 is connected to the downstream position of the first storage tank 1; the heating mechanism 4 is connected to the water bath bucket 3; the vaporizer 5 is connected to the downstream position of the second storage tank 2; the collection mechanism is connected to the output ends of the water bath bucket 3 and the vaporizer 5.

[0015] In the specific implementation process, it should be noted that the liquefied gas is stored in the first storage tank 1 and the second storage tank 2. The first storage tank 1 and the second storage tank 2 are the starting points of gas supply. Then, the gas flows from the first storage tank 1 to the water bath bucket 3 at the downstream position. The function of the water bath bucket 3 is to receive and store the liquefied gas coming from the first storage tank 1 and perform water bath vaporization on the liquefied gas. At the same time, the heating mechanism 4 is connected to the water bath bucket 3 to heat the water in the water bath bucket 3. By heating and vaporizing the liquefied gas in the water bath method, the pressure of the gas source is increased, thus ensuring the stable output of the gas. Subsequently, the vaporizer 5 is connected to the downstream position of the second storage tank 2, and its function is to convert the liquefied gas in the second storage tank 2 into a vaporized state. The vaporized gas is output through the vaporizer 5 and is ready to be mixed with the gas in the water bath bucket 3.

[0016] Finally, the collection mechanism is connected to the output ends of the water bath bucket 3 and the vaporizer 5, and is responsible for collecting and mixing the two vaporized gases. Through the water bath vaporization process of the heating mechanism 4, not only is it ensured that all the gas sources used in the process of configuring the mixed gas are in a vaporized state, but also the output stability of the gas and the filling efficiency of the mixed gas are improved. The entire working process realizes energy conservation and optimization of gas supply through the efficient utilization of solar energy.

[0017] The heating mechanism 4 is a solar water heater. As a renewable energy source, solar energy is rich in resources and can be used for free without transportation and without any pollution to the environment. The use of solar water heaters helps to save traditional energy and has a relatively low operating cost. Because solar energy is an inexhaustible energy source, using solar water heaters can significantly reduce the dependence on traditional energy sources such as electricity and gas, thus saving energy costs. The maintenance cost is relatively low, and it has a high energy conversion efficiency. Solar water heaters can make more full use of light energy, provide higher energy utilization efficiency, and have obvious long-term investment returns.

[0018] In some examples, further, the collection mechanism includes: a first pipeline 6, a manifold 7, a second pipeline 8 and a gas cylinder 9. The input end of the first pipeline 6 is connected to the water bath bucket 3; the manifold 7 is connected to the output end of the first pipeline 6; the input end of the second pipeline 8 is connected to the output end of the vaporizer 5, and the other end is connected to the manifold 7; a plurality of gas cylinders 9 are arranged at the outlet of the manifold 7.

[0019] In the specific implementation process, it should be noted that the liquefied gas is first stored in the first storage tank 1 and the second storage tank 2. Subsequently, the gas flows from the first storage tank 1 to the downstream water bath bucket 3, and during this process, the water bath bucket 3 receives the liquefied gas. At the same time, the solar water heater, as the heating mechanism 4, utilizes solar energy to heat the water in the water bath bucket 3 to achieve water bath vaporization, increase the gas source pressure, and ensure stable gas output. The liquefied gas in the second storage tank 2 flows through the vaporizer 5 to the second pipeline 8. The input end of the second pipeline 8 is connected to the output end of the vaporizer 5, and the other end is connected to the manifold 7. The manifold 7, as the core component for gas mixing, receives the gases from the first pipeline 6 and the second pipeline 8. The first pipeline 6 transports the gas in the water bath bucket 3 to the manifold 7, while the second pipeline 8 transports the vaporized gas in the vaporizer 5 to the manifold 7. In the manifold 7, the gases from two different sources are mixed to form the required mixed gas. The mixed gas then flows to a number of gas cylinders 9 arranged at the outlet of the manifold 7. The gas cylinders 9 are used to collect, store, and distribute the mixed gas for subsequent use or filling. The working process of the entire collection mechanism is automated and continuous, ensuring the stable supply and efficient collection of the mixed gas. Through the utilization of solar energy, not only the energy utilization efficiency is improved, but also the purpose of environmental protection and energy conservation is achieved, while ensuring the uniformity and stability of gas mixing.

[0020] In some examples, furthermore, a safety valve 10 is also provided at the connection between the water bath bucket 3 and the first pipeline 6. The safety valve 10 can automatically open when the pressure or temperature in the equipment or pipeline exceeds the set safety value, and prevent accidents caused by excessive pressure in the equipment and pipeline by discharging pressure or reducing temperature, thereby protecting the normal operation of the equipment and pipeline and preventing accidents. When the pressure in the water bath bucket 3 rises and exceeds the pressure set by the safety valve 10, the safety valve 10 will automatically open to release some gas or liquid to reduce the pressure in the system. It can prevent the water bath bucket 3 from bursting or being damaged due to excessive pressure, ensuring the safety of the entire gas distribution device.

[0021] In some examples, furthermore, the first storage tank 1 is a carbon dioxide storage tank, and a booster pump 11 is installed at its outlet end and is connected to the water bath tank 3 through the booster pump 11. The first storage tank 1 is a special storage tank for storing carbon dioxide. The outlet end of the first storage tank 1 is equipped with a booster pump 11, whose function is to increase the pressure of carbon dioxide so that it can smoothly pass through the pipeline and be transported to the water bath tank 3. The specific working process is as follows: Carbon dioxide is stored in the first storage tank 1 and maintained in a liquid form. When it is necessary to supply carbon dioxide to the water bath tank 3, the booster pump 11 is started to pressurize the carbon dioxide to overcome the pressure loss in the pipeline system and provide sufficient driving force. The pressurized carbon dioxide is transported from the first storage tank 1 to the water bath tank 3 through the pipeline. The solar water heater uses solar energy to heat the water in the water bath tank 3, and then heats the liquid carbon dioxide in the water bath tank 3, causing it to gradually vaporize. The vaporized carbon dioxide and other vaporized gases are collected by the collection mechanism and finally transported to the gas collecting bottle 9 for further use or filling. Through the use of the booster pump 11, not only is it ensured that carbon dioxide can flow overcoming the resistance in the system, but it also helps to improve the working efficiency and vaporization effect of the entire gas distribution device. At the same time, using solar energy as the heating source realizes energy conservation and environmental protection.

[0022] In some examples, furthermore, the second storage tank 2 is an argon storage tank, and a cryogenic pump 12 is provided at its outlet end and is connected to the vaporizer 5 through the cryogenic pump 12. The second storage tank 2 serves as an argon storage tank, and liquid argon is stored in the second storage tank 2, that is, the argon storage tank. The outlet end of the argon storage tank is equipped with a cryogenic pump 12. The working principle of the cryogenic pump 12 is to adsorb gas molecules through a cryogenic surface to achieve the purpose of pumping air. The flow rate of the cryogenic pump 12 is selected according to the gas production capacity and can meet the needs of the vaporizer. The working pressure and temperature of the cryogenic pump 12 are set according to the process requirements to ensure the safe and efficient transportation of liquid argon. The vaporizer 5 converts liquid argon into gaseous argon by absorbing ambient heat. It ensures a stable supply of argon, and through the coordinated operation of the cryogenic pump 12 and the vaporizer 5, the efficient and safe use of argon is achieved.
