What is helium leak detector？

1. Basic principle and structure of helium recovery system:

Helium recovery system is a new type of gas recovery system, which can effectively recover helium to improve the utilization efficiency of helium and reduce the consumption of helium. The basic principle of the helium recovery system is to use the gravity and temperature difference of helium to transport helium from the low temperature layer to the high temperature layer, where the low temperature layer is condensed into liquid helium, and finally recover helium from the liquid helium. The structure of the helium recovery system is mainly composed of condenser, heat exchanger, expander, scroll centrifugal pump, buffer tank and pneumatic control valve.

2. Design and optimization of helium recovery system:

The design and optimization of helium recovery system is a technical work, which needs to consider the properties of helium, the structure and performance of the recovery system. Firstly, the physical and chemical characteristics of helium gas should be considered comprehensively to determine the operating temperature and pressure of the system. Secondly, the thermal performance of the recovery system should be considered to determine the condensation temperature, heat exchange temperature and expansion temperature of the system. Finally, it is necessary to consider the dynamic characteristics of the recovery system to determine the power, recovery rate and recovery speed of the system.

3. Control and monitoring of helium recovery system:

In order to ensure the safe operation of the helium recovery system, the system needs to be fully controlled and monitored. The control of the helium recovery system is mainly realized through the pneumatic control valve, which can adjust the flow rate of the helium recovery system according to the real-time working parameters to ensure the safe operation of the system. In addition, the monitoring of the helium recovery system is also an important work, and the working parameters such as pressure, temperature and flow rate of the system should be monitored frequently to ensure the efficient operation of the system.

4. Improvement measures of helium recovery system:

Although the design and optimization of helium recovery systems have achieved great success, there are some improvements that can improve the efficiency of the system. Firstly, the thermal efficiency of the system can be improved by improving the heat exchanger and expander of the system. Secondly, the recovery rate of the system can be improved by increasing the flow rate of the vortex centrifugal pump. Finally, a new type of buffer tank can be used to improve the recovery speed of the system.

5. Safety measures for helium recovery system:

Since helium is highly toxic, effective safety measures should be taken when operating a helium recovery system. First, the operating pressure of the system should be determined according to the actual situation, and the safety valve should be set according to the preset safety pressure value. Secondly, it is necessary to regularly check the pressure resistance of each component to ensure the safe operation of the system; Finally, effective emission measures should be taken to prevent helium from polluting the environment.

6. Practical application of helium recovery system:

Helium recovery system has been widely used, its application fields involve medicine, metallurgy, fine chemical industry and other industries. In the pharmaceutical industry, helium recovery systems can be used to produce drugs to improve drug utilization efficiency; In the metallurgical industry, helium recovery systems can be used for welding to reduce welding losses; In the fine chemical industry, helium recovery systems can be used to produce liquids to improve the quality of fine chemical products.
