Description

Technical Field

[0001] The present application relates to the field of energy and chemical technology, and in particular to a multi-stage gas-water separation device. Background Art

[0002] With the continuous advancement of technology, the structure and performance of multi-stage gas-water separation devices have been continuously optimized, and space utilization and separation efficiency have been continuously improved. A multi-stage gas-water separation device typically consists of a housing, a corrugated plate separator, and other components. The gas-water mixture first enters the inner cavity of the housing and undergoes initial separation in the gravity separation chamber. The initially separated gas-water mixture then flows through the corrugated plate separator for further separation. The separated gas is discharged through the gas outlet, while the separated liquid is discharged through the liquid outlet.

[0003] In the prior art, the separation efficiency of the gas-water separation device will drop sharply after the specified flow rate of the gas-liquid mixture is exceeded. In the case of large fluctuations in flow rate, the performance of the separator may be affected. The separation plate commonly used in gravity sedimentation separators (the cross-sectional profile of the separation plate is as follows Figure 6 As shown), when separating water and microparticles in water-containing natural gas, the corrugated plate component needs to lengthen the equipment cylinder while keeping the path length unchanged, resulting in low space utilization of the separation plate in the internal cavity of the equipment cylinder.

[0004] Therefore, there is an urgent need for a multi-stage gas-water separation device with stable flow rate and high space utilization. Utility Model Content

[0005] The embodiment of the present application provides a multi-stage gas-water separation device, aiming to ensure a stable flow rate of the gas-liquid mixture while avoiding waste of space.

[0011] The vortex plate is vertically arranged at the connection point between the air intake pipe and the shell, and the vortex plate is provided with a vortex structure from the outside to the inside, which can accelerate the circulation of air and water.

[0012] Furthermore, there are gaps between the plurality of separation plates, and there are angles between adjacent separation plates, and the angles range from 10.5° to 15.5°.

[0013] Furthermore, the vortex plate is annular in structure as a whole, and a vortex hole is opened on the outer end surface of the vortex plate from the outside to the inside, and the hole core of the vortex hole forms an angle with the axis of the vortex plate.

[0014] Furthermore, a hydrophobic membrane is applied to the outer side surface of the secondary separation net, and the upper end surface of the hydrophobic membrane is flush with the upper end surface of the secondary separation net.

[0015] Furthermore, a plurality of water outlet holes are formed through the bottom surface of the shell from top to bottom. The water outlet holes are located between adjacent separation plates and are spaced apart from the bottom edges of the separation plates.

The vortex structure arranged from the outside to the inside on the side of the vortex plate close to the primary separation net can, on the one hand, moderate the flow rate of the gas-water input system from the outside, so as to ensure the stable separation ability of the gas-water sealing device.

[0029] Combine Figure 1-Figure 5 As shown, a multi-stage gas-water separation device includes a shell 10, a primary separation net 11, a secondary separation net 12, a separation plate 13, an air inlet pipe 14 and a vortex plate 15; the vertical shell 10 is internally provided with a primary separation net 11 with an overall ring-shaped structure, and the bottom of the primary separation net 11 is fixedly connected to the upper and lower inner walls of the shell 10; the secondary separation net 12 with an annular structure is spaced apart on the inner side of the primary separation net 11, and the bottom of the secondary separation net 12 is fixedly connected to the upper and lower inner walls of the shell 10; the separation plate 13 with an overall sine-cosine structure is provided. Multiple separation plates 13 are evenly arranged in the gap between the primary separation net 11 and the secondary separation net 12, and the outer end surface of the separation plate 13 is fixedly connected to the inner end surface of the primary separation net 11, and the inner end surface of the separation plate 13 is fixedly connected to the outer end surface of the secondary separation net 12; multiple air intake pipes 14 are fixedly arranged on the outside of the shell 10 and communicate with the shell 10; vortex plates 15 are vertically arranged at the connection between the air intake pipes 14 and the shell 10, and the vortex plates 15 are provided with a vortex structure from the outside to the inside, which can accelerate the circulation of gas and water.

[0030] The multi-stage gas-water separation device in the present application is used in the gas-water mixture gravity separation operation scenario, which is composed of a shell 10, a primary separation net 11, a secondary separation net 12, a separation plate 13, an air inlet pipe 14 and a vortex plate 15. Among them, the primary separation net 11 and the secondary separation net 12 are arranged in the internal cavity of the shell 10 with relative spacing, forming a multi-stage screening separation for the gas-water mixture. The separation plate 13 guides and performs secondary separation on the gas and water input into the shell 10. In this process, when the water-gas mixture is input into the shell 10, the mesh structure of the primary separation net 11 separates the gas-water mixture into large particles of water droplets, and then the screened gas-water mixture moves regularly along the output air flow along the plate surface of the separation plate 13, and the water condenses on the surface of the separation plate 13 and flows along the plate surface of the separation plate 13 to the bottom of the shell 10 and converges. The cross-sectional profile of the separation plates 13 in this application is a sine-cosine structure and is arranged circumferentially around the axis of the secondary separation net 12. This arrangement is intended to ensure that the separation plates 13 can fully utilize the limited space of the housing 10. The vortex structure of the vortex plate 15, arranged from the outside to the inside on the side close to the primary separation net 11, can, on the one hand, moderate the flow rate of the external gas and water input system to ensure the stable separation capacity of the gas-water sealing device; on the other hand, as the gas and water flow toward the primary separation net 11, the gas-water mixture can fully contact the primary separation net 11 and the separation plates 13, thereby ensuring the separation efficiency of the gas-water separation device.

[0031] There are gaps between the multiple separation plates 13, and adjacent separation plates 13 have angles ranging from 10.5° to 15.5°. This arrangement facilitates the flow of the gas-water mixture through the gaps between adjacent separation plates 13. To reduce the resistance of the separation plates 13 in the sine-cosine structure to the gas-water mixture, the angle between adjacent separation plates 13 is preferably 12°.

[0032] The vortex plate 15 is annular in structure as a whole. A vortex hole 151 is opened on the outer end surface of the vortex plate 15 from the outside to the inside. The hole core of the vortex hole 151 forms an angle with the axis of the vortex plate 15.

[0033] The vortex plate 15 in the present application is arranged at the connection point between the shell 10 and the air intake pipe 14. When the gas-water mixture passes through the air intake pipe 14, a part of the gas-water mixture passes into the internal cavity of the shell 10 through the middle part of the vortex plate 15, and the other part flows into the shell 10 through the vortex hole 151 from the outside to the inside and fully reaches the first-level separation net 11 and the plate surface of the separation plate 13 to ensure a stable flow rate of the gas-water mixture.

[0034] To prevent the gas from being contaminated by water again after gas-water separation, a hydrophobic membrane 16 is applied to the outer side of the secondary separation net 12 , and the upper end surface of the hydrophobic membrane 16 is flush with the upper end surface of the secondary separation net 12 .

[0035] In order to facilitate the staff to design an external water receiving device so that the water accumulated at the bottom of the shell 10 can be discharged to the outside of the shell 10, a plurality of water outlet holes 17 are passed through the bottom surface of the shell 10 from top to bottom. The water outlet holes 17 are located between adjacent separation plates 13 and are spaced apart from the bottom edge of the separation plate 13.

[0036] The hydrophobic membrane 16 in this application is both water-tight and air-permeable, allowing gas to collect within the area enclosed by the secondary separation network 12 and be fed to an external gas collection system. The hydrophobic membrane 16 can be one or more of a polyester film, a polyether film, a polyamide film, or a polyimide film. This configuration facilitates the selection of an economical hydrophobic membrane 16 for use in this application, thereby maximizing economic efficiency.

[0037] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0038] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
