Description

TECHNICAL FIELD

[0001] The utility model relates to the compressor gas-liquid separation field, especially relates to a integrated gas-liquid separator. BACKGROUND

[0002] The box of the existing compressor rear section gas-liquid separator is mostly opened on the plate material, and the plate material is butt welded together through fusion welding. Since the box needs to be connected with the compressor pipeline through a threaded structure, a nut is welded on the opening to form the threaded structure on the box wall surface. Since the atmosphere directly contacts the high-temperature molten pool during the fusion welding process, a large amount of metal alloy elements are oxidized, and a large amount of nitrogen, water vapor, etc. also enters the molten pool to cause pores, slag inclusions, cracks, etc. when the weld cools, which deteriorate the quality and performance of the weld and affect the strength of the box and the nut position.

[0006] Further, a separation plate is provided between the gas inlet and the exhaust port, which changes the movement direction of the mixture after entering the box and prevents it from entering the exhaust port in a straight line.

[0007] Further, the separation plate includes a first shielding surface shielding the gas inlet, and a second shielding surface and a third shielding surface are respectively provided on the side of the first shielding surface, and the second shielding surface and the third shielding surface extend towards the inner wall of the box to realize large-angle turning and acceleration of the mixture after entering the box from the gas inlet.

[0008] Further, the separation plate is connected to the upper side of the gas inlet through a fixing bracket at the top, thereby completely shielding the gas inlet.

[0009] Further, the height of the gas inlet is lower than that of the exhaust port.

[0024] Figure 1 and Figure 2 This demonstration demonstrates an integrated gas-liquid separator. This separator primarily uses a separation plate 20 within a housing 10 to redirect the flow of a gas-liquid mixture, utilizing the different boiling points between the media to separate the solids and liquids in the mixture. The central portion of the separator is the housing 10, with its upper portion 40 and lower portion 50 joined by high-frequency sealing.

[0025] The air inlet 60 and the exhaust port 70 are respectively located on the two side walls of the box body 10 opposite to each other. Since the air inlet 60 and the exhaust port 70 need to be connected with the external pipeline through screw threads, the air inlet 60 and the exhaust port 70 are first drilled on the wall surface of the box body 10 through hot melt molding, and then the holes are pulled out and finally tapped with a tap. This molding method can ensure the lateral wall thickness of the air inlet 60 and the exhaust port 70, and the integrated structure makes the connection strength improved compared with the original resistance welding method.

[0026] The separation plate 20 is arranged between the gas inlet 60 and the gas outlet 70, and the top of the separation plate 20 is provided with a fixing support 21 for connecting and fixing the separation plate 20 to the inner wall of the box 10. The other end of the fixing support 21 is specifically arranged on the upper side of the gas inlet 60, so that the gas inlet 60 is completely shielded from the side by the separation plate 20. When the high-temperature solid-liquid mixture enters the box 10 through the gas inlet 60, it is blocked by the separation plate 20 and spreads around. Since there are many media with different boiling points in the mixture, part of the substances with lower boiling points condense into liquid and flow towards the bottom of the box 10 after contacting the separation plate 20. The separation plate 20 has a first shielding surface 22 which shields the gas inlet 60 in the front, and a second shielding surface 23 and a third shielding surface 24 which are respectively arranged on the two sides of the first shielding surface 22. In order to further increase the contact area of the mixture with the separation plate 20 when the mixture enters the gas inlet 60, the second shielding surface 23 and the third shielding surface 24 are arranged to extend towards the inner wall of the box 10, so that the mixture is further deflected under the action of the second shielding surface 23 and the third shielding surface 24 after changing the flow direction under the action of the first shielding surface 22, thereby better forming a vortex in the box 10.

[0027] The safety valve port 41 of the upper portion 40 is also machined and threaded after fusion molding. The lower portion 50 is shrunk by high-frequency heating to form a blowdown port 51 with a reduced inner diameter at the bottom. The blowdown port 51 and the pressure relief port 41 are coaxially arranged. The liquid flows downward along the separation plate 20 and finally flows out of the box 10 through the blowdown port 51. The safety valve port 41 at the top can be used to install a pressure relief valve. The box 10 is also provided with a pressure gauge mounting port 30.
