At present, gas pretreatment technology mainly relies on traditional constant temperature devices, which usually use heaters or coolers to adjust the temperature of the gas. However, these devices have problems such as inaccurate temperature control, slow response speed, and high energy consumption, which may lead to inaccurate measurement results and affect the reliability of gas analysis. Especially in application scenarios where gas temperature needs to be precisely controlled, traditional technologies cannot meet the requirements of high efficiency and high precision.

The liquid storage tank 9 as the main body of the device stands steadily on the ground through four corner pillars; the liquid storage tank 9 as a container for temperature-controlled liquid medium (such as silicone oil) is designed with sufficient capacity and suitable shape to ensure a good heat exchange effect, and a cover plate 12 is provided at the upper end of the liquid storage tank 9. The liquid storage tank 9 is connected and sealed to the cover plate 12 through a buckle 10 on the edge, and an electric stirrer 1 is installed on the upper end surface of the cover plate 12. The stirring blades of the electric stirrer 1 are inserted into the bottom of the liquid storage tank 9 to stir the temperature-controlled liquid medium to ensure uniform temperature distribution and avoid local temperature differences. According to the size of the liquid storage tank 9 and the viscosity of the temperature-controlled liquid medium, it is ensured that the entire temperature-controlled liquid medium can be effectively stirred;

[0029] An air inlet 4 is provided at the upper end of one side of the liquid storage tank 9, and an air outlet 8 is provided at the lower end of the opposite side. An air pipe 13 is connected between the air inlet 4 and the air outlet 8. The air pipe 13 is made of stainless steel and is arranged in the liquid storage tank 9 in a spiral structure to increase the contact area between the gas and the medium and improve the heat exchange efficiency.

[0030] The upper end surface of the cover plate 12 is provided with a temperature sensor 3, and the probes of the temperature sensor 3 are installed at both ends of the air inlet 4 and the air outlet 8 of the air pipe 13, and are used to monitor the temperature of the medium in the liquid storage tank 9 in real time and provide accurate temperature data;

[0031] A semiconductor refrigerator 5 is fixedly mounted on the third side of the liquid storage tank 9, and the semiconductor refrigerator 5 is used to heat or cool the temperature control medium to achieve rapid temperature regulation;

[0032] The pressure sensor 6 is located at the lower end of the semiconductor refrigerator 5 and is used to monitor the pressure changes of the liquid in the liquid storage tank 9 and the gas in the gas pipe to ensure the safe operation of the system;

[0033] The upper end surface of the cover plate 12 is provided with a liquid level gauge 11 for monitoring the liquid level in the liquid storage tank 9 to ensure the sufficiency of the temperature control medium; the upper end surface of the cover plate 12 is provided with a handle 2;

[0034] The solenoid valve 7 is located below the liquid storage tank 9 and is used in conjunction with the temperature sensor 3 and the pressure sensor 6 to automatically adjust the valve opening according to the feedback signal of the sensor, and adjust the working state of the electric stirrer 1 and the semiconductor refrigerator 5 to maintain the gas temperature within a preset range.

[0035] The working principle of the present invention is:

[0036] When the gas needs to be precisely temperature controlled, the gas is first introduced into the stainless steel gas pipe 13 in the liquid storage tank 9. The electric stirrer 1 is started to ensure that the gas and the liquid medium are fully in contact and evenly mixed, and the pressure sensor 6 monitors the pressure changes of the liquid in the liquid storage tank 9 and the gas in the gas pipe in real time. The temperature sensor 3 monitors the gas temperature in real time. When the temperature is lower than the preset value, the control system starts the semiconductor refrigerator 5 to heat the liquid medium; conversely, if the temperature is higher than the preset value, the cooling function is started. In this way, the gas can reach the required test temperature before entering the measurement chamber, thereby ensuring the accuracy of the measurement results.

[0037] In a laboratory environment, when helium needs to be analyzed and tested, the liquid reservoir 9 is first cleaned and checked for leaks to ensure its sealing performance. Subsequently, according to the design requirements of the pretreatment system and the characteristics of the gas, an appropriate amount of silicone oil is added to the liquid reservoir 9, and the cover 12 of the liquid reservoir 9 is fixed by the buckle 10. The solenoid valve 7 is adjusted to set the helium temperature required for the experiment, the semiconductor refrigerator 5 is controlled to control the silicone oil temperature for preheating, and the electric stirrer 1 is started to avoid uneven local temperature of the silicone oil. Before the helium enters the device, it is first preliminarily purified and stabilized through the pretreatment pipeline. The helium is introduced into the stainless steel air pipe 13 in the liquid reservoir 9, and the electric stirrer 1 continuously stirs to ensure that the helium and silicone oil are fully in contact with heat transfer and evenly mixed. The pressure sensor 6 monitors the pressure changes of the silicone oil in the liquid reservoir 9 and the helium in the air pipe in real time to ensure the safe operation of the system. The temperature sensor 3 monitors the helium temperature in real time. When the temperature is lower than the preset value, the solenoid valve 7 starts the semiconductor refrigerator 5 to heat the silicone oil; conversely, if the temperature is higher than the preset value, the cooling function is started. In this way, the helium can reach the required test temperature before entering the measurement chamber. When the temperature sensor 3 confirms that the helium has reached the required temperature, the solenoid valve 7 will instruct the gas outlet 8 to open, allowing the gas to smoothly enter the measurement chamber for subsequent analysis and measurement.

[0038] In practical applications, the high-efficiency gas constant temperature pretreatment device of the present invention can be used for the pre-measurement treatment of gases such as helium. For example, in the semiconductor manufacturing process, the purity and temperature of helium are crucial to the production process. By using the device of the present invention, the helium can be pre-treated at a constant temperature before entering the measurement chamber to ensure that its temperature reaches the required test conditions, thereby improving the accuracy of the measurement results.
