Description

Technical Field

[0002] Affected by special situations such as power supply interruption, cold storage, cold chain transport vehicles, data centers, etc. may experience abnormal interruption of cooling supply. At this time, it is necessary to quickly activate the emergency cold source system to maintain a low-temperature environment. Most of the existing emergency cold source systems use ice or eutectic salt for cold storage, with a relatively slow response speed, a single cold release rate, and manual intervention is required to return to the standby state after the response, making it difficult to adapt to complex situations. Carbon dioxide hydrate is a high latent heat energy storage working medium with a controllable phase change temperature, a fast decomposition refrigeration speed, and can be generated in multiple cycles. Using these excellent properties of carbon dioxide hydrate, a new type of emergency cold source system can be designed to adjust the refrigeration duration by controlling the cold release rate and can automatically return to the standby state. In addition, the carbon dioxide gas required for synthesizing the hydrate can also be obtained by treating carbon-containing waste gases such as flue gas, realizing "negative carbon refrigeration", which is beneficial to energy conservation and emission reduction.

[0022] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0023] Example 1: As Figure 1 shown, a reusable emergency cold source system using carbon dioxide hydrate with fast response, adjustable pressure relief, and intelligent reset includes a reactor 1, a hydrate storage tank 2, a heat exchanger 3, a visualization console 4, gas pretreatment equipment 5, a water storage tank 6, a hydrate pump 7, liquid pumps 8, 9, gas pumps 10, 11, a pressure relief valve 12, a Hall sensor 13, and supporting pipelines, circuits, valves, and control systems. Among them, the pump refers to a pump valve with the functions of a pump and a valve.

[0024] The gas pretreatment equipment 5 and the water storage tank 6 are respectively connected to the nozzles at the top of the reactor 1 through the gas pumps 10, 11 and the liquid pumps 8, 9; the bottom end of the reactor 1 is connected to the hydrate storage tank 2 through the hydrate pump 4; one side of the heat exchanger 3 is connected to the inside of the hydrate storage tank 2, and the other side is the cold-using end; the top end of the hydrate storage tank 2 is connected to the gas pretreatment equipment 5 through the gas pump 10, and the side where the main solution is enriched is connected to the water storage tank 6 through the liquid pump 8; the pressure relief valve 12 (including a pressure sensor) is arranged in the hydrate storage tank 2, and the Hall sensor 13 is installed in the main circuit, and both are connected to the console.

[0025] The console monitors the power supply status through the Hall sensor 13. When the power supply is interrupted, the pressure relief valve is opened to decompose the stored hydrate for refrigeration. When the power supply is restored, the pressure relief is stopped, and the decomposed carbon dioxide gas and the main solution are sent back to the reactor to regenerate the hydrate, and then stored in the hydrate storage tank 2.

[0026] The reactor 1 includes a mechanical stirrer and a micro-nano bubble nozzle to accelerate the synthesis of hydrates. The visualization console 4 includes a super capacitor for power supply to ensure that the system logic is controllable within 30 seconds after power failure. The hydrate storage tank 2 uses a ceramic or metal sintered filter element (pore size 1 - 5 μm) to intercept hydrate particles and allow the solution to pass through, thereby separating the hydrate slurry from the main solution. The main solution contains water and a chemical promoter; preferably, tetrabutylammonium bromide (TBAB) is used as the chemical promoter to improve the hydrate synthesis conditions (278.15K, 3.6MPa). The pressure relief valve 12 includes an electromagnetic proportional valve and a fast pressure relief valve, which can achieve a 90% sudden drop in pressure within 10 seconds and linearly adjust the opening degree through the proportional valve.

[0027] The control console monitors the power supply status through the Hall sensor 13. When the power supply is interrupted, the pressure relief valve 12 is opened to decompose the stored hydrate for refrigeration. When the power supply is restored, the pressure relief is stopped, and the decomposed carbon dioxide gas and the main solution are sent back to the reaction kettle 1 to regenerate the hydrate, and then stored in the hydrate storage tank 2.

[0028] The Hall sensor 13 is connected to the main circuit of the refrigeration system to monitor its working status. When the main refrigeration system is powered off and stops running, the Hall sensor 13 sends a signal to the control console 4. The control console 4 judges that the refrigeration system is working abnormally by combining daily working data and environmental conditions, and sends a signal to the pressure relief valve 12. The pressure relief valve 12 quickly releases pressure and reduces the pressure to the decomposition threshold within 0.5 seconds. At the same time, the pressure sensor gives real-time feedback, and the pressure relief rate is finely adjusted through the proportional valve. The carbon dioxide hydrate stored in the storage tank 2 decomposes for refrigeration, and the cold energy is released to the environment through the heat exchanger 3 to maintain a low-temperature environment.

[0029] After the hydrate in the hydrate storage tank 2 decomposes, carbon dioxide gas and the main solution containing additives are generated. After the power supply is restored, the main solution is pumped into the water storage tank 6 by the liquid pump 8, and then pumped into the reaction kettle 1 by the liquid pump 9. Carbon dioxide is pumped into the gas pretreatment device 5 by the air pump 10 for impurity removal and other treatments, and then pumped into the reaction kettle 1 by the air pump 11. In the reaction kettle 1, the two are recombined into a carbon dioxide hydrate slurry, and then pumped back into the hydrate storage tank 2 by the hydrate pump 7 for storage for the next use.

[0030] Example 2: As Figure 1 shown, a reusable emergency cold source system provided in this embodiment includes a reaction kettle 1, a hydrate storage tank 2, a heat exchanger 3, a visualization control console 4, a gas pretreatment device 5, a water storage tank 6, a hydrate pump 7, liquid pumps 8 and 9, air pumps 10 and 11, pressure relief valves 12, a Hall sensor 13, and supporting pipelines, circuits, valves and control systems.

[0031] The reaction kettle 1 is used to synthesize carbon dioxide hydrate, and there is a sprayer inside to add carbon dioxide and the main solution, and an external constant temperature water bath. To accelerate the synthesis speed, the reaction kettle also includes a mechanical stirrer and a micro-nano bubble generator; the hydrate storage tank 2 is designed to withstand high pressure and is used to store carbon dioxide hydrate. One side of the heat exchanger 3 is connected to the hydrate storage tank 2, and the other side releases cold air to the environment; the gas pretreatment device is used to perform impurity removal, heat exchange, and compression treatments on the carbon dioxide gas returned to the cycle; the water storage tank 6 temporarily stores the unused main solution and plays a buffering role.

[0032] The inlet of the hydrate pump 7 is connected to the reaction kettle 1, and the outlet of the hydrate pump 7 is connected to the hydrate storage tank 2; the inlet of the liquid pump 8 is connected to the hydrate storage tank 2, and the outlet of the liquid pump 8 is connected to the water storage tank 6; the inlet of the liquid pump 9 is connected to the water storage tank 6, and the outlet of the liquid pump 9 is connected to the reaction kettle 1; the inlet of the gas pump 10 is connected to the gas pretreatment equipment 5, and the outlet of the gas pump 10 is connected to the reaction kettle 1.

[0033] The pressure relief valve 12 and the Hall sensor 13 are connected to and controlled by the visualization console 4, which is used to monitor and real-time regulate the working state of the system. Further, the console 4 integrates the LSTM algorithm.

[0034] The working process of the present invention will be described in detail below: The Hall sensor 13 is connected to the main circuit of the refrigeration system to monitor its working state. When the main refrigeration system is powered off and stops running, the Hall sensor 13 sends a signal to the console 4. The console 4 combines the daily working data and environmental conditions to judge that the refrigeration system is working abnormally, and sends a signal to the pressure relief valve 12. The pressure relief valve 12 quickly releases pressure and reduces the pressure to the decomposition threshold within 0.5 seconds. At the same time, the pressure sensor feeds back in real time, and the pressure relief rate is finely adjusted through the proportional valve. The carbon dioxide hydrate stored in the storage tank 2 decomposes to refrigerate, and the cold quantity is released to the environment through the heat exchanger 3 to maintain a low-temperature environment.

[0035] After the hydrate in the storage tank 2 decomposes, carbon dioxide gas and the main solution containing additives are generated. After the power supply is restored, the main solution is pumped into the water storage tank 6 by the liquid pump 8, and then pumped into the reaction kettle 1 by the liquid pump 9; carbon dioxide is pumped into the gas pretreatment equipment 5 by the gas pump 10 for impurity removal and other treatments, and then pumped into the reaction kettle 1 by the gas pump 11. In the reaction kettle 1, the two are recombined into a carbon dioxide hydrate slurry, which is then pumped back into the hydrate storage tank 2 by the hydrate pump 7 for storage for next use.

[0036] The present invention uses carbon dioxide hydrate for cold storage and utilization, and has the advantages of fast refrigeration response speed, adjustable refrigeration rate, high cold storage density, and self-rapid recovery after refrigeration. This technology can quickly respond in the event of a sudden power supply interruption, provide an emergency cold source to maintain a low-temperature environment, and can solve the problems of slow response speed and single cold release speed of traditional systems. The present invention uses carbon dioxide hydrate. When the power supply is normal, the carbon dioxide hydrate is stored in the hydrate storage tank. When the power supply suddenly stops, the Hall sensor will immediately send a signal to be received by the visualization console, and thus make a reaction. Under the signal of the console, the hydrate storage tank will start to release pressure, resulting in the decomposition of the hydrate to release cold quantity and continuously provide a low-temperature environment. The water and carbon dioxide decomposed from the hydrate enter the reaction kettle through the valve. After the power supply is restored, the reaction kettle will immediately start to recombine the hydrate slurry, which is then pumped back into the hydrate storage tank by the hydrate pump for storage.

[0037] The above detailed description is a specific description of the feasible embodiments of the present invention, and such embodiments are not intended to limit the patent scope of the present invention. Any equivalent implementation or modification without departing from the present invention shall be included in the patent scope of this case.
