Abstract

The invention relates to a moisture recycling supersonic speed gas-purification separation device for moisture recycling, dehydration, liquid removal, purification and separation; the device comprises a convergent divergent nozzle, a recycling port, a recycling separation cavity, a straight length and a diffuser pipe; the left end of a tapering section of the convergent divergent nozzle is provided with a moisture inlet, the right end thereof is connected with an inner shell body in the straight length by the diverging section of the convergent divergent nozzle, a swirler is arranged in the inner shell body of the straight length, and the right end of the swirler is provided with a swirler fixed sleeve which is hollow, and the right end of the swirler fixed sleeve and the left end of the inner shell of the diffuser pipe form a ring-shaped channel. The recycling separation cavity is formed between the straight length and the diffuser pipe, the recycling port is arranged on the wall surface of the inner shell body of the straight length, so as to effectively lead liquid drops in the remaining recycling gas to be separated out in a swirling way. The device realizes moisture recycling, purification and separation, so as to improve the separation efficiency and environmental-protection benefit; furthermore, the device has the advantages of no chemical pollution, environmental protection and energy saving, compact structure and high circulating and utilizing value.

Description

technical field

[0001] The invention is a moisture recirculation supersonic gas purification and separation device, which belongs to thermal energy-saving purification device and is mainly used in the field of moisture circulation dehydration, liquid removal, purification and separation. Background technique

[0002] Natural gas flowing from oil and gas wells generally contains H 2 S, water, heavy hydrocarbons and other substances. During the gathering and transportation process, at a relatively high temperature (close to or higher than 20°C), water can easily combine with hydrocarbons with smaller molecules to form hydrates, or form liquid water droplets at lower temperatures Or solid ice, causing pipelines, valves and various instruments to be blocked, the flow area is reduced, and the pressure drop of the pipeline is increased. In addition, liquid water readily dissolves CO 2 、H 2 S and other acid gases form corrosive acid liquid, causing corrosion of pipelines and eq...
