[0025] refer to Figure 1As shown, one embodiment of this utility model is as follows:

[0026] A photovoltaic-coupled hydrate decarbonization in-situ monitoring device includes a hydrate purification and decarbonization system, the hydrate purification and decarbonization system being connected to an in-situ Raman monitoring system, and the hydrate purification and decarbonization system and the in-situ Raman monitoring system being connected to a solar photovoltaic system.

[0027] Specifically, the hydration purification and decarbonization system includes a first gas storage tank 1, a booster pump 2, a first buffer tank 3, a hydration tower 4, a second buffer tank 5, a compressor 6, and a second gas storage tank 7 arranged in sequence. The jacket cavity of the hydration tower 4 is connected to a first high and low temperature constant temperature bath 8, which is connected to the solar photovoltaic system.

[0028] The in-situ Raman monitoring system includes a Raman reactor 9, which is connected to a Raman monitor 10. The Raman reactor 9 is connected to the hydration tower 4. The jacketed cavity of the Raman reactor 9 is connected to a second high-low temperature constant temperature bath 11, which is connected to the solar photovoltaic system.

[0029] A liquid transfer pump 12 and a check valve are installed on the connecting pipe between the Raman reactor 9 and the hydration tower 4.

[0030] The solar photovoltaic system includes a solar panel 13, which is connected to an energy storage battery 14. The energy storage battery 14 is connected to the first high and low temperature constant temperature bath 8 and the second high and low temperature constant temperature bath 11.

[0031] The hydration tower 4 is equipped with a stirring mechanism 15, which is connected to the energy storage battery 14. The hydration tower is also equipped with a heating wire assembly to cooperate with the first high and low temperature constant temperature bath 8 to control the reaction temperature in the hydration tower and accelerate the hydrate formation and decomposition reaction rate.

[0032] Furthermore, both the hydration tower 4 and the Raman reactor 9 are connected to temperature control probes to accurately measure the reaction temperature, facilitating precise temperature control of the high and low temperature constant temperature bath. During the hydrate formation stage, the stirring mechanism 15 rapidly stirs the mixture, promoting thorough mixing of carbon dioxide and water to form solid CO2 hydrate at 273K. Impurity gases such as nitrogen and oxygen do not participate in the hydration reaction and are vented after the hydration reaction is complete. During the decomposition stage, the stirring mechanism 15 reduces its rotation speed to avoid damaging the hydrate structure and improve decarbonization efficiency. At 298K, the solid CO2 hydrate decomposes and reforms into CO2 gas.

[0033] The solar photovoltaic system ensures the stable operation of the Raman spectrometer, enabling real-time monitoring of hydrate structural changes. By analyzing Raman spectra, the state information of carbon dioxide molecules within the hydrate is obtained, allowing for adjustments to the operation of the hydrate purification and decarbonization system based on Raman monitoring data.

[0034] By introducing a solar photovoltaic system, solar energy is converted into electricity, providing a stable power source for the hydration purification and decarbonization system and the in-situ Raman monitoring system. This reduces operating costs and minimizes indirect carbon emissions from traditional energy generation, aligning with the concept of green development. Energy storage batteries ensure the full utilization of abundant solar energy resources and guarantee continuous operation of the equipment.

[0035] The solar panels are high-efficiency monocrystalline or polycrystalline silicon solar panels, and the number and layout of the panels are determined according to the overall power requirements of the device. A maximum power point tracking (MPPT) controller is configured to adjust the working status of the solar panels in real time to ensure that they always output maximum power. After being optimized by the MPPT controller, the electrical energy can be directly supplied to the power-consuming devices of the hydration purification and decarbonization system and the in-situ Raman monitoring system, or stored in energy storage batteries to power the system when there is insufficient sunlight or at night, ensuring the continuous operation of the system.

[0036] The Raman spectrometer in this embodiment is equipped with a laser source of suitable wavelength and a high-sensitivity detector. Through a connected fiber optic probe, the laser is introduced into the Raman reactor to monitor the hydrate sample in real time, obtaining the kinetic parameters of the hydrate decarbonization process. This provides a basis for optimizing process parameters, thereby improving decarbonization efficiency.

[0037] Furthermore, a carbon dioxide analyzer 16, a flow meter 17, and a back pressure valve 18 are installed on the connecting pipe between the hydration tower 4 and the second buffer tank 5.

[0038] A circulation pipe 19 is also provided on the connecting pipe between the hydration tower 4 and the second buffer tank 5. The outlet end of the circulation pipe 19 is connected to the booster pump 2, and the inlet end of the circulation pipe 19 is located between the hydration tower 4 and the carbon dioxide analyzer 16.

[0039] The carbon dioxide infrared analyzer 16 can monitor the CO2 concentration in real time to determine the reaction progress. When the outlet concentration is low, it can be controlled by a valve on the pipeline. The CO2 gas is then fed into the booster pump 2 through the circulation pipe 19, and then into the hydration tower 4 to regenerate hydrates for continuous separation, achieving a final recovery concentration of over 90%. The hydration tower is also equipped with an vent pipe to directly discharge any remaining nitrogen gas that failed to form hydrates after the hydration reaction is complete. The hydration tower is connected to a storage tank 20, which stores a thermodynamic accelerator solution. The storage tank 20 is pumped into the hydration tower to promote the carbon dioxide hydration reaction. In this embodiment, a DIOX thermodynamic accelerator solution is specifically used.

[0040] The function of the back pressure valve is to maintain a constant pressure at the pump outlet and prevent damage to the system caused by pressure fluctuations. At the same time, by adjusting the valve opening, the pressure in the pipeline can be kept within a certain range, thereby effectively preventing backflow.

[0041] The main function of compressor 6 is to increase the pressure of CO2 produced after decomposition, so that CO2 can enter the second gas storage tank 7.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
