Embodiment Construction

[0059] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0060] like figure 1 As shown, a full-swirl supersonic separation device includes a shell and a central swirl component. Among them, the shell includes a steady flow constriction section 1 and a diffuser separation section 2 connected in sequence, such as figure 2 shown.

[0061] definition figure 1 The left end is the front end of the separation device, and the steady flow contraction section 1 is located at the front side of the diffuser separation section 2.

[0062] The central swirl part is located in the shell, that is, in the steady flow constriction section 1 and the diffuser separation section 2 .

[0063] The steady flow constriction section 1 includes a straight pipe steady flow section 3 and a Laval nozzle tapering section 4 .

[0064] The steady flow section 3 of the straight pipe is located at the front side of the tapering s...

Abstract

The invention discloses a full-swirl supersonic separation device, which comprises a shell and a central swirl component. The casing includes the straight-flow steady flow section, the Laval nozzle converging section and the Laval nozzle expansion section. The central swirl component includes a front central swirl component and a rear central swirl component; the front central swirl component is located in the straight flow stabilization section and the Laval nozzle tapering section; the rear central swirl component is located in the Laval nozzle expansion section. When the gas enters the straight-line steady flow section and the tapering section of the Laval nozzle, the gas flow expands in a swirling state, and reaches supersonic speed after reaching the expansion section of the Laval nozzle, the temperature and pressure further decrease, and the gas begins to condense. The process of streamside condensation can effectively reduce the influence of droplet re-evaporation; in addition, a swirl component is also installed in the expansion section of the Laval nozzle, and its swirl capacity is strong and durable, which ensures the separation effect and separation efficiency of the device.

Description

technical field [0001] The invention belongs to the technical field of low-temperature condensation and cyclone separation, and in particular relates to a full-swirl supersonic separation device, which is especially suitable for low-temperature condensation and cyclone separation of impurity components such as water vapor, acid gas, and heavy hydrocarbons in natural gas. Background technique [0002] In the field of natural gas exploitation, the currently extracted natural gas is often saturated with water vapor and contains some heavy hydrocarbon components. In order to meet the requirements of natural gas export and use, water vapor, acid gas and heavy hydrocarbon components must be separated. [0003] Traditional natural gas separation processes include cooling method, chemical absorption method, adsorption method and membrane separation method. However, these separation processes have various disadvantages in the natural gas separation process, and it is urgent to propos...
