Description

TECHNICAL FIELD

[0001] The utility model relates to compressed air energy storage technical field, specifically, it is an integrated gas source device with heating function. BACKGROUND

[0002] As an important power source, the gas source device is mainly used for storing and releasing high-pressure gas, is the storage equipment of compressed gas, and is the core component of the gas pressure transmission system. When the existing high-pressure gas source device is used in a low-temperature environment, the gas pressure is prone to decrease due to the decrease in temperature (such as volume contraction or gas liquefaction), which leads to insufficient release gas pressure, unstable gas supply, and even gas supply interruption, so that the gas pressure transmission system cannot be normally used. The working principle of the gas source device is that, according to the ideal gas state equation PV = nRT (where P is the gas pressure, V is the gas volume, n is the amount of gas substance, R is the gas constant, and T is the gas temperature), for the high-pressure gas source device with a fixed volume, the gas pressure in the bottle is mainly affected by the amount of gas substance and the gas temperature. When the gas temperature decreases in a low-temperature environment, the gas pressure decreases, so the gas temperature can be restored by heating to ensure the gas pressure. When the amount of gas substance in the bottle decreases due to the release of gas, the gas pressure decreases, and within a certain range, the gas pressure can also be ensured by increasing the gas temperature through heating.

[0003] At present, the gas source device used is generally a single large-capacity gas source device. The existing gas source device has the problems of poor heating uniformity, long time required for heating recovery to the target gas pressure, poor interchangeability, high cost, and the like. Therefore, it is necessary to design a gas source device with a heating function to meet the use requirements of the gas source device in a low-temperature environment. UTILITY MODEL CONTENT

[0044] This embodiment is based on Embodiment 1. Firstly, it facilitates the handling of bottle 1 by installing it in the bottle rack 2. Secondly, it increases the stability of bottle 1. Thirdly, it facilitates the installation of the bottle rack 2 in the pneumatic transmission system, ensuring the normal operation of the pneumatic transmission system. Using the integrated air source device provided in this embodiment, a handle 6 is also provided on the front end face of the bottle 1; and multiple connecting screws 10 are provided on the side of the bottle rack 2. The bottle rack end cap 11 and sealing cap 17 are respectively fixed to the rear mounting cavity and front mounting cavity at both ends of the bottle rack 2 by the connecting screws 10. Simultaneously, mounting holes 8 are provided on both ends of the bottle rack 2. The mounting holes 8 include front mounting holes and rear mounting holes, with four holes in each direction. Specifically, one front mounting hole is located on the bottle rack 2 between two adjacent bottle bodies 1 at the front end of the bottle rack 2, and one rear mounting hole is located on the bottle rack 2 on the outer side of the bottle body 1 at the rear end of the bottle rack 2.

[0045] The integrated gas source device with heating function described in this utility model works as follows: Four independent cylinders 1 are integrated and installed in a cylinder rack 2. A heating oil chamber 23 is formed between the cylinder 1 and the cylinder rack 2, and an oil inlet 25 communicating with the heating oil chamber 23 is provided on the side of the cylinder rack 2. Heat transfer oil is filled into the heating oil chamber 23 through the oil inlet 25, and the heat transfer oil is heated by the heater 16. In this way, the cylinder 1 can be uniformly heated by the heat transfer oil. At the same time, since a second safety valve 14 and a temperature and pressure sensor 15 are installed on the connecting valve 21, the threshold of the safety valve can be selected as needed (for example, when the gas pressure in the cylinder exceeds 52MPa, the first safety valve 4 automatically opens to release pressure). High-pressure gas (such as nitrogen) stored in the cylinder 1 is injected from the inflation valve 5 and released from the connecting valve 21, conduit 12 and multi-port nozzle connector 13 in the gas outlet unit 26. Pressure gauge 3 can display the gas pressure inside bottle 1 in real time. The temperature and pressure sensor 15 includes a temperature sensor and a pressure sensor. The temperature sensor is used to detect the gas temperature passing through the gas outlet unit 26, and the pressure sensor is used to detect the gas pressure passing through the gas outlet unit 26. By detecting the temperature and pressure, the gas temperature and pressure inside bottle 1 are determined, and the signals are transmitted to an external controller. The external controller can then control the gas as needed. For example, when the temperature and pressure sensor detects that the gas pressure inside the bottle is lower than the set value of 32MPa, the external controller starts the heater 16 to increase the gas pressure to the target gas pressure of 35MPa, and then turns off the heater 16. When the temperature and pressure sensor 15 detects that the gas pressure inside bottle 1 exceeds the set maximum value of 37MPa, the external controller issues an alarm and prompts the user to manually open the second safety valve 14 to release pressure. When the temperature and pressure sensor 15 detects that the gas temperature inside bottle 1 is higher than the set maximum value of 70℃, the external controller disconnects the power supply to the heater 16 and issues an alarm prompting the user to check the gas source device.

[0046] Therefore, the integrated gas source device described in this utility model has multiple receiving cavities within the bottle rack 2, each housing a bottle 1. A heating oil chamber 23 is formed between the bottle 1 and the receiving cavity in the bottle rack 2. A heater 16 is installed in the heating oil chamber 23, and the electric heating wire in the heater 16 is used to heat the oil injected into the heating oil chamber 23. This maintains the gas in the bottle 1 in an ideal state through heating, effectively avoiding pressure fluctuations caused by low temperature. Furthermore, the multiple bottles 1 arranged within the bottle rack 2 improve the interchangeability of the gas source device, thereby reducing operating costs. Additionally, each bottle 1 is equipped with a pressure... Table 3 and the first safety valve 4 are provided, while the connecting valve 21 is equipped with a second safety valve 14 and a temperature and pressure sensor 15. Both the first safety valve 4 and the second safety valve 14 are pressure relief valves. The first safety valve 4 is an automatic pressure relief valve, while the second safety valve 14 is a manual pressure relief valve. The pressure gauge 3 is used to detect the pressure inside the bottle 1, and the temperature and pressure sensor 15 is used to detect the gas temperature and gas pressure passing through the connecting valve 21. Automatic pressure relief can be achieved through the first safety valve 4, while rapid pressure relief can be achieved through the second safety valve 14. The bottle 1 is heated by oil, which makes the gas temperature inside the bottle 1 rise quickly, the gas heating area is large and the heating uniformity is good, and the time required to restore the target gas pressure is short.

[0047] In summary, the integrated gas source device described in this utility model can effectively solve the problem of gas pressure drop caused by gas temperature decrease in low-temperature environments. It is particularly suitable for application scenarios that require high-pressure gas supply. Its overall structure is simple, its design is reasonable, and it is convenient to operate and use, making it suitable for widespread application.
