Technical Field

[0001] The present application relates to the technical field of gas-liquid property detection, and in particular, to a gas-liquid property detection system. Background Art

[0002] The determination of gas-liquid reaction properties, such as the diffusion coefficient, solubility, reaction kinetics and other properties of gas-liquid, and the reliable design and development of gas-liquid reaction processes have important guiding significance in chemical operations and applications such as chemical engineering and environment.

[0003] In the related art, the determination of the solubility parameters of gas in liquid is usually carried out through the volume saturation method, pressure decay method, bubble point method and the like. However, the determination of gas-liquid properties is greatly affected by environmental factors (such as temperature), resulting in poor accuracy of the test results obtained by the existing experimental equipment and methods. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a gas-liquid property detection system to improve the accuracy of gas-liquid property detection.

[0005] An embodiment of the present application provides a gas-liquid property detection system, comprising: a gas supply pipeline, one end of which is connected to a gas supply device, and a gas mass flow meter and a gas preheater are provided on the gas supply pipeline, and the gas preset device is used to adjust the temperature of the gas in the gas supply pipeline; a liquid supply pipeline, one end of which is connected to a liquid supply device, and a liquid preheater is provided on the liquid supply pipeline, and the liquid preset device is used to adjust the temperature of the liquid in the gas supply pipeline; a gas-liquid reaction device, the other ends of the gas supply pipeline and the liquid supply pipeline extend into the gas-liquid reaction device, and the gas in the gas supply pipeline can enter the liquid supply pipeline in the gas-liquid reaction device and dissolve in the liquid in the liquid supply pipeline; wherein the temperatures of the gas and liquid entering the gas-liquid reaction device are the same.

[0006] In the above implementation process, the gas-liquid property detection system includes: a gas supply pipeline, a liquid supply pipeline and a gas-liquid reaction device. Among them, one end of the gas supply pipeline is connected to the gas supply device, the gas supply device is used to provide a gas source, and a gas preheater is provided on the gas supply pipeline. The gas preheater can adjust the temperature of the gas in the gas supply pipeline and make the temperature of the gas reach a preset temperature threshold; one end of the liquid supply pipeline is connected to the liquid supply device, the liquid supply device is used to provide liquid for gas-liquid reaction, and a liquid preheater is provided on the liquid supply pipeline. The liquid preheater can adjust the temperature of the liquid in the liquid supply pipeline and make the temperature of the liquid in the liquid supply pipeline the same as the temperature of the gas in the gas supply pipeline. The other ends of the gas supply pipeline and the liquid supply pipeline extend into the gas-liquid reaction device. The gas-liquid reaction device can provide a closed gas-liquid reaction environment and can keep the temperatures of the gas and liquid consistent. In the gas-liquid reaction device, the gas can enter the liquid reaction tube through the tube wall of the liquid reaction tube and dissolve in the liquid in the liquid reaction tube. Therefore, after the system is stable, the solubility of the gas-liquid reaction can be quickly obtained by reading the indication of the gas mass flow meter, and the data of various properties of the gas-liquid reaction, such as the diffusion system and reaction kinetics, can be obtained through model fitting, thereby avoiding the influence of temperature changes on the test results of the gas-liquid reaction experiment and effectively improving the accuracy of the gas-liquid reaction experimental data.

[0007] It is worth noting that the liquid pipeline used for circulating liquid in the gas-liquid reaction device is a fluorine-containing polymer thin-walled tube, the gas pipeline used for circulating gas is a stainless steel tube, and the liquid pipeline is located inside the gas pipeline. In this way, the gas can be dissolved in the liquid in the liquid pipeline through the pipe wall of the liquid pipeline, and it is ensured that the liquid in the liquid pipeline cannot flow out into the gas pipeline through the pipe wall.

[0009] In the above implementation process, the automatic pressure reducing valve has the function of automatically adjusting the gas pressure in the gas supply pipeline, that is, it can automatically reduce the inlet pressure in the gas pipeline to the required outlet pressure, and rely on the energy of the gas itself to automatically keep the outlet pressure stable, thereby improving the stability of the gas flow in the gas supply pipeline.

[0010] In a possible implementation, it also includes: a first pressure sensor, which is provided on the gas supply pipeline and located between the automatic pressure reducing valve and the gas preheater, and is used to detect the pressure value of the gas flowing out of the automatic pressure reducing valve; a controller, which is electrically connected to the automatic pressure reducing valve and the first pressure sensor, and the controller is used to receive the pressure value and control the automatic pressure reducing valve to perform an action according to the pressure value so that the pressure value is adjusted to a preset pressure value.

[0011] In the above implementation process, by setting a first pressure sensor between the automatic pressure reducing valve and the gas preheater, the first pressure sensor can monitor the pressure of the gas in the gas supply pipeline in real time and transmit the pressure signal to the controller. The controller can adjust the pressure setting value of the automatic pressure reducing valve according to the pressure signal detected by the first pressure sensor, thereby realizing the regulation of the outlet pressure in the gas supply pipeline, so as to test the gas and liquid under different pressures, and improve the automation level of the gas-liquid property detection process.

[0013] In the above implementation process, the first one-way valve is used to control the on-off of the gas output and prevent the gas from flowing back to the gas mass flow meter, thereby improving the safety of product use.

[0014] The gas inlet valve is used to control the on-off between the gas supply device and the gas supply pipeline. The filter plays a filtering role and is used to filter impurities in the gas source, which helps to improve the cleanliness of the gas and ensure the accuracy of gas-liquid reaction data detection.

[0015] In a possible implementation, a liquid delivery pump is provided between the liquid supply device and the liquid preheater, and a first one-way valve is provided between the liquid delivery pump and the liquid preheater.

[0016] In the above implementation process, by arranging a liquid delivery pump on the liquid supply pipeline between the liquid supply device and the liquid cooling preheater, the liquid delivery pump can automatically control the flow rate, pressure and pressure pulsation of the liquid in the liquid supply pipeline, so as to facilitate the delivery of liquids with different flow rates, flow rates and pressures through the liquid supply pipeline. Therefore, by changing the liquid flow rate, the gas flow meter readings at different liquid flow rates can be obtained, and then the diffusion coefficient of the gas in the liquid can be obtained through model fitting.

[0017] The first one-way valve is used to realize the circulation of liquid in the liquid supply pipeline after passing through the liquid delivery pump, and can ensure the continuity of liquid supply by the liquid delivery pump.

[0018] In a possible implementation, a second pressure sensor is provided on the liquid supply pipeline, and the controller is electrically connected to the second pressure sensor and the liquid delivery pump.

[0019] In the above implementation process, by setting a second pressure sensor on the liquid supply pipeline, the second pressure sensor can monitor the pressure of the liquid in the liquid supply pipeline in real time and transmit the liquid pressure signal to the controller. The controller can control the liquid delivery pump to adjust the pressure of the liquid supply pipeline according to the liquid pressure signal detected by the second pressure sensor, so as to facilitate the reaction of liquids and gases at different pressures, thereby obtaining test data of the reaction of liquids and gases at different pressures.

[0020] Exemplarily, a pressure relief valve electrically connected to the controller is also provided on the air supply pipeline and the liquid supply pipeline. When the pressure of the air supply pipeline or the liquid supply pipeline is greater than a preset pressure threshold, the controller can control the pressure relief valve to perform an action to ensure the safe use of the air supply pipeline and the liquid supply pipeline.

[0022] In the above implementation process, a heat and cold regulating device is arranged outside the gas-liquid reaction device. The heat and cold regulating device (such as a water bath or a heating and cooling device, etc.) can regulate the temperature inside the gas-liquid reaction device so that the temperature inside the gas-liquid reaction device can be maintained at a preset temperature and kept constant, so as to measure the parameters of the gas-liquid reaction in the gas-liquid reaction device under different temperature conditions.

[0023] In a possible implementation, it further includes: a gas output pipeline and a liquid output pipeline, wherein the gas output pipeline and the liquid output pipeline are respectively connected to the gas outlet and the liquid outlet of the gas-liquid reaction device.

[0024] In the above implementation process, the gas output pipeline is connected to the gas outlet of the gas-liquid reaction device, and is used to supply the gas after the gas-liquid reaction is completed to discharge the gas-liquid reaction device; the liquid output pipeline is connected to the liquid outlet in the gas-liquid reaction device, and is used to supply the liquid after the gas-liquid reaction is completed to discharge the gas-liquid reaction device.
