Embodiment 1
[0043] like figure 1 As shown, a vapor-liquid two-phase flow pipeline system is connected between the outlet of the heat exchange equipment and the inlet 4 of the fractionation tower, and consists of two branch pipelines 2-1 / 2-2 and a main pipeline 3, of which two The axis of the horizontal pipe 10-1a / 10-2a of the branch pipeline and the axis of the main pipeline 3 are in the same plane.
[0044]In the branch pipeline A2-1, the outlet 1-1 of the heat exchange equipment A is reduced in the vertical direction by the size head 7, and then connected to the 90° elbow 5 through the vertical pipeline 9, and the main pipeline is connected to the 90° elbow 5 After the 3 direction is turned, the horizontal pipeline 10-1a is connected, and the horizontal pipeline 10-1a is connected to a horizontal pipeline after being turned by the 45° elbow 6. After that, the branch pipeline 2-1 is connected to the end of the main pipeline 3 through the 45° elbow 6 ; In the branch pipeline B2-2, the ou...
Embodiment 2
[0046] like figure 2 As shown, a vapor-liquid two-phase flow pipeline system is connected between the outlet 1-1 / 1-2 / 1-3 of the heat exchange equipment and the inlet 4 of the fractionation tower, and consists of three branch pipelines 2-1 / 2 -2 / 2-3 and the main pipeline 3, wherein the plane formed by the axes of the horizontal pipes 10-1a / 10-2a / 10-3a of the three branch pipelines is above the horizontal plane where the axis of the main pipeline 3 is located.
[0047] In the branch pipeline A2-1, the outlet A1-1 of the heat exchange equipment is connected to a vertical pipeline 9 upwards, and then turns to the main pipeline 3 through a 90° elbow to connect to the horizontal pipeline 10-1a, and then turns to the horizontal pipeline 10-1a through a 90° elbow 5 To the top of the main pipeline 3, after that, connect the obliquely downward pipeline 11 (obliquely to the flow direction of the material flow) downward at an angle of 45 °, and change the diameter through the large and sm...
Embodiment 3
[0049] like image 3 As shown, a vapor-liquid two-phase flow pipeline system is connected between the outlet 1-1 / 1-2 of the heat exchange equipment and the inlet 4 of the fractionation tower, and consists of two branch pipelines 2-1 / 2-2 and the total Composed of pipelines 3, the horizontal plane where the axis of the branch pipeline 2-1 horizontal pipe 10-1a is located is located below the horizontal plane where the axis of the main pipeline 3 is located, and the horizontal plane where the axis of the branch pipeline 2-2 horizontal pipe 10-2a is located is located below the horizontal plane where the axis of the main pipeline 3 is located above.
[0050] In the branch pipeline A2-1, the outlet A1-1 of the heat exchange equipment is changed in the vertical direction through the size head 7, then passes through a vertical pipeline 9, and then turns to the horizontal pipeline 10-1a through the 90° elbow 5, The horizontal pipe is connected to a 45° upward straight pipe 12 (obliqu...
