Abstract

A transonic speed controllable vortex gas dehumidifier adopts a mode generating vortex through a static cascade of a vortex generator. A shell of the dehumidifier and a vortex controller form an annular jet tube, the vortex intensity of gas-liquid phase flows is controlled by changing the flow passage area of an annular space to realize the condensation and separation process of components and achieve the purpose for improving the separation efficiency and lowering the flow loss by combining a high-effective back-pressure device. The dehumidifier can change the mode generating vortex, control the change of the vortex intensity in the processes of component condensation, component separation, back pressure, and the like, improve the component separation efficiency and reduce the total pressure loss. The invention has the advantages of no addition of medical agent, low weight, compact space structure, small occupied area, low cost, unmanned operation, high inherent safety, and the like, thereby having wide application prospect in the fields of the separation and the liquefaction of high-pressure mixed gases, and the like.

Description

technical field [0001] The invention relates to the technical field of gas drying treatment, in particular to the technical field of dehumidification of water vapor and heavy hydrocarbons in natural gas. It is a multi-component gas separation and dehumidification device, specifically a transonic controllable vortex gas dehumidification device that removes one or more components in the mixed gas flow. Background technique [0002] The transonic controllable vortex gas dehumidification device can be applied in many industrial technical fields, such as dehydration and dehydrocarbon treatment of oil and gas, gas treatment in various fields such as environment, chemical industry, and building materials. [0003] Dehumidification of high pressure gases is a frequently encountered task in industrial processes. For example, the natural gas extracted from the formation is often mixed with liquid water and water vapor, condensate, heavy hydrocarbon gas, solid particles, etc. Before t...
