Abstract
The utility model relates to a tangential inlet type gas supersonic swirl flow separator which mainly consists of a tangential inlet section, a contraction section, an expanding section and a diffuser pipe and is applied to fields of multi-component mixed gas separation and the like. The tangential inlet section enables gas to enter a channel tangentially to form a stable swirl flow, and the airflow is stably accelerated after entering the contraction section and reaches sound velocity at the throat. With reduction of the flow area and the rotation radius, the swirl flow is strengthened according to the law of conservation of angular momentum. The airflow is expanded to reach supersonic velocity at the expanding section to form low temperature and low pressure, so that moisture in the gas or water and heavy hydrocarbon in natural gas can ne condensed. At the same time, condensate droplets are thrown to the wall by huge centrifugal force generated by rotation of the air flow so as to separate gas and liquid efficiently. The liquid enters a liquid accumulation chamber and the dry gas is in the center of a pipeline and flows out after the operation of back pressure implemented by the diffuser pipe. The device is simple in structure, has high processing and assembling precision, supports unmanned operation and has wide application prospect, and the addition of chemical agents is not needed.
