With the development of the chemical industry, especially in the fields of hydrometallurgy, element separation, and drug extraction, extraction is a very important part. For systems with significant differences between the organic phase and the aqueous phase, existing technologies usually use bubbling devices to perform bubbling operations, generating bubbles coated with the extraction liquid on the surface, and then passing the bubbles coated with the extraction liquid into the aqueous phase, Achieve efficient extraction of required products under high contrast. However, when the flow rate of gas or extraction liquid is high, using traditional bubbling devices cannot maintain a stable pressure field, allowing it to generate bubbles at a stable rate. Moreover, the diameter of bubbles generated by traditional bubbling devices is unstable and fluctuates greatly. The generation of larger diameter bubbles reduces the specific surface area of the bubbles, resulting in a decrease in the contact surface between the extraction liquid and water, and reduces the extraction rate.

This field requires the research of a new bubbling device that can generate uniformly sized bubbles at a stable speed at fast gas and extraction liquid flow rates without the need for other complex equipment.

Bubbling is a low energy intensive operation that enhances mass and heat transfer processes. Bubbling injection is one of the common solid and liquid injection methods in industry and laboratory, and is widely used in many industrial fields and experimental research such as chemistry, chemical engineering, and environmental protection. For example, the use of bubble method to produce tritiated water vapor Precursors of processes such as bubbling ald (atomic layer deposition)/cvd (chemical vapor deposition)/mocvd (metal organic chemical vapor deposition), bubbling to prepare experimental feed gas, bubbling to salt concentrated seawater, etc. Compared to injection pumps combined with vaporization tanks and other injection methods, the bubbling method has more advantages in solid and high boiling liquid sample injection. The injection pump cannot perform solid injection, and for high boiling liquid samples, the gasification after the pump is more difficult. If complete gasification cannot be achieved, some samples will still exist in liquid form, making it impossible to determine the content of vaporized samples. The bubbling method utilizes the carrier gas to enhance the volatilization process of the sample, allowing solid samples and high boiling liquid samples to be directly converted into the gas phase, and the gasification step can be omitted. At the same time, bubbling utilizes the vapor pressure property of the sample, which is only related to the nature and temperature of the sample. As long as the temperature of the sample is controlled properly, stable injection can be achieved. On the other hand, the injection concentration of the sample can also be adjusted by changing the sample temperature and vapor pressure.

The problem with bubbling injection is how to accurately quantify it. Especially in the field of chemical engineering, when it comes to certain important chemical reactions, it is necessary to strictly control the injection amount and proportion of reactants. Under industrial and laboratory conditions, using the saturated vapor pressure of the sample to calculate the injection volume is the most common method. However, this method assumes that the sample in the bubbler is always in a saturated vapor state, and factors such as the structure and bubbling conditions of the bubbler can affect the bubbling state. Previous research results have shown that only the bubbler is sufficiently slender and the carrier gas is introduced to form enough bubbles, Only then can the liquid sample evaporate sufficiently close to the saturated vapor pressure of the sample. The bubblers used in practice rarely meet the requirements, so the method of calculating sample injection volume using saturated vapor pressure has significant errors and can only be used in situations where the accuracy of sample injection volume is not high. Other quantitative methods, such as liquid level measurement and pre and post weighing, also have their own shortcomings. The liquid level measurement method can only be used for liquid samples and cannot measure the injection volume of solid samples. At the same time, due to the fact that it can only measure the liquid level changes of liquid samples over a period of time, real-time observation of the sample injection volume cannot be achieved, and thus the sample injection volume cannot be controlled in real time. Therefore, the expected injection effect can be achieved by changing the carrier gas flow rate or sample temperature. Compared to the liquid level measurement method, the front and rear weighing method can measure solid samples, but its main drawback is the same as the liquid level measurement method, which cannot measure and control the sample injection amount in real-time.

The use of other quantitative instruments such as chromatography, spectral absorption, and ultrasound can accurately quantify the bubbled sample, but chromatography is expensive and requires operators to have a certain foundation in chromatography, requiring training to master operating standards and procedures. On the other hand, each sampling of chromatography requires a certain amount of time, which cannot meet the requirements of real-time measurement; Infrared spectral absorption method (such as Horiba's ir-300 gas concentration detector) requires knowledge of the infrared absorption efficiency of the tested substance and is expensive; The ultrasonic method (such as the Piezocon gas concentration sensor from Veeco company) uses the principle that the speed of sound is inversely proportional to the half power of the average molecular weight of the mixed gas. The gas concentration is derived by measuring the speed of sound, but the molecular weight of the carrier gas and the sample need to differ greatly. Generally, hydrogen or helium is used as the carrier gas, which limits certain applications.
