[0026] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.
[0027] This embodiment discloses an air compressor that includes a parallel pipeline structure with an air-water separator. For example... Figure 1 As shown, the parallel pipeline structure of the gas-water separator includes a first main exhaust pipeline 1, a second main exhaust pipeline 5, multiple first branch exhaust pipelines 2, multiple gas-water separators 3, multiple second branch exhaust pipelines 4, and multiple drainers 6. One end of each of the multiple first branch exhaust pipelines 2 is connected to and communicates with the first main exhaust pipeline 1. The gas-water separator 3 has an air inlet, an exhaust outlet, and a drain outlet. The multiple gas-water separators 3, multiple first branch exhaust pipelines 2, multiple second branch exhaust pipelines 4, and multiple drainers 6 correspond one-to-one. The other end of each of the multiple first branch exhaust pipelines 2 is connected to multiple air inlets. One end of each of the multiple second branch exhaust pipelines 4 is connected to multiple exhaust outlets. The drainers 6 are connected to the drain outlets. The second main exhaust pipeline 5 is connected to and communicates with the other end of each of the multiple second branch exhaust pipelines 4. High-temperature compressed air enters the first main exhaust pipe 1 after passing through the cooler. After passing through the first main exhaust pipe 1, it enters multiple first branch exhaust pipes 2. Then, it enters the gas-liquid separator 3 through the air inlet for gas-liquid separation. The condensate separated in the gas-liquid separator 3 is discharged outward through the drain outlet and drainer 6. The compressed gas separated in the gas-liquid separator 3 enters the second branch exhaust pipe 4 through the exhaust outlet. The compressed gas merges through multiple second branch exhaust pipes 4 into the second main exhaust pipe 5 and returns to the system through the second main exhaust pipe 5.
[0028] The first sub-exhaust branch 2, the gas-water separator 3 and the second sub-exhaust branch 4 are connected in parallel between the first main exhaust pipeline 1 and the second main exhaust pipeline 5. The gas-water separator 3 is connected to the inlet and outlet of the gas-water separator 3. The condensed water separated by the gas-water separator 3 is discharged through the water drain 6. The flow is shared by the gas-water separator 3, so that the pressure loss of each gas-water separator 3 is relatively small, thereby reducing the pressure loss of the entire system; the parallel connection of the gas-water separator 3 can more effectively process the gas-water mixture, can share the load, reduce the pressure of a single gas-water separator 3, thereby improving the separation efficiency; and the parallel connection allows one of the gas-water separators 3 to be maintained or replaced without stopping the entire system, reducing downtime, improving operational flexibility, and reducing costs. At the same time, in the parallel pipeline structure of the gas-water separator of the embodiment, the pipeline structure connected in parallel can be flexibly adjusted as needed. If more gas-water mixture needs to be processed in the future, the specification and number of gas-water separators 3 can be adjusted to expand.
[0029] In the embodiment, the number of the first sub-exhaust branch 2, the second sub-exhaust branch 4, the gas-water separator 3 and the water drain 6 is two. Two parallel paths are achieved by two first sub-exhaust branches 2, two gas-water separators 3 and two second sub-exhaust branches 4. The flow is shared by the two gas-water separators 3, and the pressure loss of each gas-water separator 3 is relatively small, thereby reducing the pressure loss of the entire system.
[0030] Specifically, the shape formed by the two second sub-exhaust branches 4 is Y-shaped, so that the compressed gas in the two second sub-exhaust branches 4 flows through the Y-shaped exhaust pipeline to achieve confluence. The compressed gas after confluence flows into the second main exhaust pipeline 5 and returns to the system through the second main exhaust pipeline 5.
[0031] The shape of the first sub-exhaust branch 2 is inverted U-shaped, and the two ends of the bottom of the first sub-exhaust branch 2 are respectively connected to the first main exhaust pipeline 1 and the inlet. The steam-water mixture formed after the high-temperature compressed air passes through the cooler enters the two first sub-exhaust branches 2 through the first main exhaust pipeline 1. The parallel configuration of the inverted U-shaped first sub-exhaust branch 2 can increase the processing capacity of the system, so that the two gas-water separators 3 work together to process larger gas-water mixture flow. At the same time, the shape of the first sub-exhaust branch 2 is inverted U-shaped, and the inverted U-shaped first sub-exhaust branch 2 can reduce the pipeline vibration caused by the impact of compressed gas turbulence on the pipeline through the structure of first bending upward.
[0032] The air inlet and the water outlet are respectively located at the top and the bottom of the gas-water separator 3, and the air outlet is located at the side of the gas-water separator 3. The condensed water separated in the gas-water separator 3 flows into the water drain 6 through the bottom of the gas-water separator 3 and is discharged through the water drain 6. Meanwhile, the separated gas enters into the second branch air outlet 4 from the side and returns to the system through the second main air outlet 5.
[0033] In the embodiment, the gas-water separator 3 is a cyclone gas-water separator. The gas-water mixture enters into the cyclone gas-water separator from the top, passes through the internal cyclone guide vane, and more effectively separates the gas and the condensed water.
[0034] The second main air outlet 5 is connected with the two second branch air outlets 4 through flanges. The first branch air outlet 2 is connected with the gas-water separator 3 through flanges. The gas-water separator 3 is connected with the second branch air outlet 4 through flanges. The flange connection has good sealing performance and is convenient to install and connect.
[0035] The above only discloses the preferred embodiment of the utility model, and of course cannot limit the scope of the utility model, so equivalent changes made according to the utility model claim still belong to the scope covered by the utility model.
