Description
Technical Field
The application relates to the technical field of supercritical carbon dioxide filling, and particularly discloses a supercritical carbon dioxide filling protection device.
Background
The supercritical carbon dioxide is the supercritical state of carbon dioxide, namely the carbon dioxide exceeds the critical temperature, the critical pressure and the critical volume state of carbon dioxide gas liquid along with the change of temperature and pressure. When the temperature is higher than 31.1 ℃ and the pressure is higher than 7.38Mpa, the carbon dioxide enters a supercritical state.
Supercritical carbon dioxide has a strong solvating power and the strength of a conventional liquid solvent, whereas the density of supercritical carbon dioxide increases with increasing pressure and decreases with increasing temperature, and is very sensitive to pressure and temperature near the critical point, and a small temperature-pressure change can cause a sharp change in density.
When various data of supercritical carbon dioxide are researched, firstly, the pressure data of the supercritical carbon dioxide may need to be far larger than the critical pressure of the supercritical carbon dioxide, and research data are tested, and secondly, the traditional critical carbon dioxide filling pressure protection device is huge in structure, so that the installation and debugging in a laboratory are not convenient. Accordingly, the present inventors have provided a supercritical carbon dioxide charged guard device to solve the above problems.
Disclosure of Invention
The invention aims to solve the problem that the pressure of the traditional supercritical carbon dioxide filling protection equipment exceeds a set threshold value when the traditional supercritical carbon dioxide filling protection equipment is used for carrying out experiments, so that the protection equipment is failed.
In order to achieve the above object, the basic scheme of the present invention provides a supercritical carbon dioxide charging protection device, which comprises a carbon dioxide gas supply assembly and a pressure servo assembly which are in secondary communication, and is characterized in that: the safety valve is characterized by further comprising a gas storage assembly and a protection assembly, wherein the gas storage assembly is communicated with the pressure servo assembly, the protection assembly comprises a buffer tank communicated with the gas storage assembly, the gas storage assembly and the buffer tank are both communicated with a pressure relief assembly, the pressure relief assembly comprises a safety valve, a rupture disc and a pressure sensor which are arranged in parallel, and a back pressure valve is communicated between the gas storage assembly and the buffer tank and on the buffer tank; the pressure servo assembly, the backpressure valve and the pressure relief assembly are electrically connected with an electric control system, and a pressure gauge electrically connected with the electric control system is arranged between the pressure servo assembly and the gas storage assembly.
The principle and effect of this basic scheme lie in:
1. the carbon dioxide gas supply assembly supplies carbon dioxide to the pressure servo assembly, and the carbon dioxide entering the pressure servo assembly is supplied to the gas storage assembly after being continuously pressurized, so that the carbon dioxide completes the continuous pressurizing process in the gas storage assembly until reaching the specified pressure and completing the conversion from the carbon dioxide to the supercritical carbon dioxide state.
2. In the process of filling supercritical carbon dioxide, when the pressure exceeds the ideal pressure value of an experimenter, an operator can firstly adjust the pressure of gas in the gas storage component through a back pressure valve between the gas storage component and the buffer tank and between the buffer tanks, so that the continuous rise of the pressure is prevented, and dangers are prevented; unnecessary gas can get into in the buffer tank, when the pressure in the buffer tank exceeded the ideal value, in the middle of the operator's accessible buffer tank goes up the gas that the intercommunication back pressure valve will have let out the temporary storage and put into the air to guarantee that the pressure of buffer tank lasts the rising, appear dangerously.
3. After the operator finds that the pressure is too high and can not use the back pressure valve to reduce to safe pressure, when pressure constantly risees this moment, alright automatic trigger pressure relief subassembly accomplishes the pressure release process. Specifically, after an operator operates the backpressure valve, the numerical value of a pressure gauge between the pressure servo assembly and the gas storage assembly is continuously increased, and the electric control system can control the pressure servo assembly to stop working at the moment, so that the pressure servo assembly is prevented from being pressurized; after the gas storage assembly is filled, after the back pressure valve loses pressure relief capacity, a safety valve connecting pipe communicated with the gas storage assembly works, the safety valve adjusts pressure through a pre-tightening spring, if the pressure is too high, the spring is jacked open to release redundant gas, and the valve is closed again after the pressure is recovered to be normal; if the relief valve is invalid, then take over work with the rupture disk that gas storage component communicates: after the safety valve of the reaction section rupture disk fails, the rupture disk ruptures after the gas reaches the upper pressure safety limit of the explosion venting diaphragm, and a large amount of gas is vented until the pressure is equal to the atmospheric pressure. The work of gradually relieving pressure is completed, so that the safety of experimenters is ensured. In the whole process, the pressure sensor can monitor the pressure value of gas flowing out of the fracturing pipe to remind an operator to adjust the pressure in the pipe through the operation of the backpressure valve.
4. Similarly, if the back pressure valve of the buffer tank section loses functional capability, the pressure relief assembly communicated with the buffer tank can repeat the pressure relief process to complete the pressure relief work.
