The invention relates to power engineering, in particular to methods of gas reduction at gas-distribution stations of gas-transportation mains, and can be used in devices for vortex separation of inlet flow for use of separated flows with different temperatures in different technologies of temperature treatment for initial flow, and other products. A vortex tube includes in the body inlet channels for high-pressure flow connected to the hot flow cavity connected through the diaphragm to the cavity of cold flow and low-pressure outlets of those cavities, according to the invention, includes an additional cavity as a circular chamber that connects the hot flow cavity through its tangent windows to low-pressure outlet. According to the other embodiment, the vortex tube includes an additional cavity as a circular chamber at outside of the cold flow cavity and flow mixer connected to the cold flow cavity and circular chamber that is connected to the hot flow cavity. According to the other embodiment, the vortex tube includes additional cavities as circular chambers outside of those cavities, and flow mixer, and the hot flow cavity through tangent windows is connected with circular chambers and cuts in the body between those to flow mixer connected to the cold flow cavity and the low pressure outlet. On the basis of those embodiments a device and a method for gas reduction are developed. A compact vortex tube is provided with increased power intensity and increased complex effectiveness and reliability of gas reduction. |
