Embodiment 1
[0051] Design a heat exchanger, which is mainly composed of shell, tube sheet, heat exchange tube, tube box, baffle plate, etc. The material is not limited, such as figure 1 shown. The tube-side fluid enters from the tube-side inlet nozzle 9 on the right tube box 8, flows through the heat exchange tube bundle 17 from left to right, collects in the left tube box 2, and is discharged from the tube-side outlet nozzle 1; the shell-side fluid flows from the cylindrical The shell side inlet joint 4 of the cylinder 5 enters, and under the action of the baffle, the shell side flows radially, forming a cross flow with the tube side fluid, and finally discharges through the shell side inlet joint 7 of the cylinder 5 .
[0052] The heat exchange tube bundle is fixed by the left tube plate 3 and the right tube plate 7 welded to the cylinder body 5, and passes through each baffle. Both the tube sheet and the baffle (ring-shaped and disc-shaped) have plate holes consistent with the outer d...
Embodiment 2
[0058] According to the plate hole arrangement principle of the present invention, the following steps are adopted to determine the position of the plate holes.
[0059] ①As attached figure 2 As shown, a polar coordinate system is established, the origin of the coordinate system is placed at the center of the tube sheet, the radial coordinate is r, and the circumferential coordinate is . Set the first plate hole in the center of the tube plate.
[0060] ② Determine the minimum spacing d of the plate holes s . With (r=0) as the center, d s Make the first concentric circle for the radius, and set 6 plate holes evenly on the concentric circle according to the principle (3), and the center of one of the plate holes is located at superior. The spacing of these 6 plate holes satisfies d s ≥1.25d requirement.
[0061] ③According to the method for determining the radius of concentric circles, the radius of the second concentric circle is calculated to be 2d s , 6 plate hol...
