Description

Technical Field

[0001] The utility model relates to the technical field of separators, in particular to a tangential gas-liquid separator. Background Art

[0002] The concentrated liquid evaporates in the equipment to form secondary steam, which contains liquid foam. It is necessary to separate the steam and the liquid foam. The existing technology uses a multi-layer baffle structure to block the droplets for separation, or Chinese patent number CN204699523U discloses a nuclear island steam gas-liquid cyclone separator, which uses a gas-liquid separation device to separate gas and liquid. Although gas-liquid separation can be performed, the structure is complex and the manufacturing cost is high. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the invention

[0003] The utility model aims to provide a tangential gas-liquid separator, which can significantly reduce the liquid foam entrained in the secondary steam, simplify the structure and reduce the production cost.

[0004] In order to achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted by the utility model is: a tangential gas-liquid separator, characterized in that it includes a gas-liquid inlet pipe, a first gas-liquid outlet pipe and a second gas-liquid outlet pipe arranged on the outer peripheral side of the gas-liquid inlet pipe, the mouth direction of the first gas-liquid outlet pipe is opposite to the outlet direction of the second gas-liquid outlet pipe, the first gas-liquid outlet pipe and the second gas-liquid outlet pipe are respectively connected to the gas-liquid inlet pipe, and the first gas-liquid outlet pipe and the second gas-liquid outlet pipe are respectively tangentially connected to the gas-liquid inlet pipe.

[0005] As a preferred technical solution, the first gas-liquid outlet pipe is arranged along the tangent direction of the outer peripheral side of the gas-liquid inlet pipe, and the inner diameter of the first gas-liquid outlet pipe gradually increases; the second gas-liquid outlet pipe is arranged along the tangent direction of the outer peripheral side of the gas-liquid inlet pipe, and the inner diameter of the second gas-liquid outlet pipe gradually increases.

[0006] As a preferred technical solution, a cover plate is detachably provided at one end of the gas-liquid inlet pipe.

[0007] As a preferred technical solution, the outer arc diameter of the first gas-liquid outlet pipe is smaller than the outer arc diameter of the first gas-liquid outlet pipe.

[0008] As a preferred technical solution, the outlet of the first gas-liquid outlet pipe, the outlet of the second gas-liquid outlet pipe and the central axis of the gas-liquid inlet pipe are located in the same plane.

[0009] As a preferred technical solution, the cover plate is connected to the gas-liquid inlet pipe flange.

[0010] The beneficial effects of the utility model are:

[0011] 1) The secondary steam enters the gas-liquid inlet pipe. Due to the tangentially connected first gas-liquid outlet pipe and second gas-liquid outlet pipe, the secondary steam will form a vortex and collide with the pipe wall. After the collision, the liquid foam forms condensate and falls back into the equipment from the gas-liquid inlet pipe. The secondary steam is discharged from the first gas-liquid outlet pipe and the second gas-liquid outlet pipe respectively, which can significantly reduce the liquid foam entrained in the secondary steam, simplify the structure, and reduce the production cost;

[0012] 2) The cover plate is connected to the gas and liquid inlet flange for easy installation and disassembly;

[0013] 3) The outer arc diameter of the first gas-liquid outlet pipe is the same as the outer arc diameter of the second gas-liquid outlet pipe, so that the vortex formation effect is better, thereby further reducing liquid foam. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figure 1-Figure 2 The utility model provides a tangential gas-liquid separator, comprising a gas-liquid inlet pipe 1, a first gas-liquid outlet pipe 2 and a second gas-liquid outlet pipe 3 arranged on the outer peripheral side of the gas-liquid inlet pipe 1, the mouth direction of the first gas-liquid outlet pipe 2 is opposite to the outlet direction of the second gas-liquid outlet pipe 3, the first gas-liquid outlet pipe 2 and the second gas-liquid outlet pipe 3 are respectively connected to the gas-liquid inlet pipe 1, and the first gas-liquid outlet pipe 2 and the second gas-liquid outlet pipe 3 are respectively tangentially connected to the gas-liquid inlet pipe 1.

[0020] A first hole (not marked) and a second hole (not marked) are provided on the wall of the gas-liquid inlet pipe 1, so that the first gas-liquid outlet pipe 2 and the second gas-liquid outlet pipe 3 are connected to the gas-liquid inlet pipe 1, and secondary steam enters the gas-liquid inlet pipe 1. Due to the tangential connection between the first gas-liquid outlet pipe 2 and the second gas-liquid outlet pipe 3, the secondary steam will form a vortex, and the vortex will drive the liquid foam to collide with the pipe wall. After the collision, the condensate is formed and falls back into the equipment from the gas-liquid inlet pipe 1. The secondary steam is discharged from the first gas-liquid outlet pipe 2 and the second gas-liquid outlet pipe 3 respectively, which can significantly reduce the liquid foam entrained in the secondary steam, simplify the structure, and reduce the production cost.

[0021] like Figure 1-Figure 2 As shown, the first gas-liquid outlet pipe 2 is arranged along the tangential direction of the outer peripheral side of the gas-liquid inlet pipe 1, and the inner diameter of the first gas-liquid outlet pipe 2 gradually increases. The second gas-liquid outlet pipe 3 is arranged along the tangential direction of the outer peripheral side of the gas-liquid inlet pipe 1, and the inner diameter of the second gas-liquid outlet pipe 3 gradually increases. The outer arc surface of the first gas-liquid outlet pipe 2 is not concentric with the gas-liquid inlet pipe 1, and the second gas-liquid outlet pipe 3 is not concentric with the gas-liquid inlet pipe 1. The variable diameter structure is conducive to the formation of vortex, which can better drive the liquid foam to hit the tube wall and is also conducive to the discharge of secondary steam.

[0022] like Figure 1-Figure 2 As shown, a cover plate 4 is detachably provided at one end of the gas-liquid inlet pipe 1. Furthermore, the cover plate 4 is flange-connected to the gas-liquid inlet pipe 1. The cover plate 4 can block secondary steam, and the flange connection facilitates installation and disassembly.

[0023] like Figure 1-Figure 2 As shown, the outer arc diameter of the first gas-liquid outlet pipe 2 is equal to the outer arc diameter of the first gas-liquid outlet pipe 2, and the outer arc diameter of the first gas-liquid outlet pipe 2 is the same as the outer arc diameter of the second gas-liquid outlet pipe 3, so that the vortex effect is better, thereby further reducing liquid foam.

[0024] like Figure 1-Figure 2 As shown, the outlet of the first gas-liquid outlet pipe 2, the outlet of the second gas-liquid outlet pipe 3 and the central axis of the gas-liquid inlet pipe 1 are located in the same plane, the gas-liquid flow direction is stable, and the vortex formation effect is good.
