Tracer particle generating and separating device for natural gas flow field measurement

The invention relates to a tracer particle generating and separating device for natural gas flow field measurement. The tracer particle generating and separating device is composed of a tracer particle generating part and a tracer particle separating part. The tracer particle generating part comprises a high-pressure kettle, a high-pressure gas source and an atomizing nozzle; and the tracer particle separating part comprises a cyclone separator, a liquid collecting tank and a baffle plate separator. According to the tracer particle generating and separating device, the particle generating device and the particle separating device are effectively combined; tracer particles are screened by a cyclone plate and a baffle plate to be uniform and small in particle size, the requirements of the non-contact LDV and PIV speed measurement technology for high following performance and consistency of the tracer particles are met, and the measurement accuracy of LDV and PIV natural gas flow fields is improved.
