[0030] like Figure 2 As shown, Figure 2 Components with the same name are considered the same component. In the heterogeneous polymerization reactor 1, initiators, acids, catalysts, etc., can be added through the feed port. The heterogeneous polymerization reactor 1 is connected to a vacuum system, allowing for internal vacuuming. During vacuuming, the low-boiling-point initiator enters the low-boiling-point separation tower 3 for low-boiling-point separation.

The product with a polymerization degree of 10-50 generated in the polymerization kettle 2 is transported to the heterogeneous polymerization kettle 1, and is esterified with organic acid and catalyst.

A first oil separation plate 52, a primary distribution disc 53, a second oil separation plate 54, a secondary distribution disc 55, and a defoaming plate 56 are sequentially arranged from top to bottom inside the hollow conical cylindrical structure of the shell 51. The bottom of the shell 51 is provided with a water phase outlet 58, and the shell 51 above the first oil separation plate 52 is provided with an oil phase outlet 57.
[0042] As shown in Figure 4 The first oil separation plate 52 is a semicircular structure, and the arc-shaped part of the first oil separation plate 52 is in contact with the inner wall of the shell 51.

The arc-shaped part of the primary distribution disc 53 is in contact with the inner wall of the shell 51, and the gap between the primary distribution disc 53 and the shell 51 is located on the opposite side of the shell 51 from the gap between the first oil separation plate 52 and the shell 51.
[0044] As shown in Figure 6 The second oil separation plate 54 is a semicircular structure, and the arc-shaped part of the second oil separation plate 54 is in contact with the inner wall of the shell 51.

[0045] As shown in Figure 7As shown, the secondary distribution tray 55 is an arcuate structure, and a plurality of downcomers 511 are arranged on the secondary distribution tray 55. The arcuate part of the secondary distribution tray 55 is in contact with the inner wall of the shell 51, and the secondary distribution tray 55 is located directly below the primary distribution tray 53.
[0046] As shown in the figure, the defoaming plate 56 is an arcuate structure, and the defoaming plate 56 is a metal corrugated mesh plate. The arcuate part of the defoaming plate 56 is in contact with the inner wall of the shell 51, and the defoaming plate 56 is located directly below the secondary distribution tray 55. Figure 8
[0047] The low-boiling substance is condensed, and then input from the top of the shell 51 of the two-phase separator 5. Under the action of the first oil separation plate 52, the primary distribution tray 53, the second oil separation plate 54, the secondary distribution tray 55, and the defoaming plate 56, oil-water separation is realized. The oil phase is transported to the low-boiling substance separation tower 3 from the oil phase output port 57, and the water phase is transported outward from the water phase output port 58 for recycling.

The second oil separation plate 54 forms an angle of 1° with the horizontal plane, and the gap between the second oil separation plate 54 and the shell 51 is the lowest at the horizontal position of one end. When the oil-water mixture impacts on the first oil separation plate 52 and the second oil separation plate 54, it will run to the gap between the first oil separation plate 52, the second oil separation plate 54, and the shell 51, which is more conducive to oil-water separation.

The side length of the regular hexagonal hole at the lower end is smaller than that of the regular hexagonal hole at the upper end, and the regular hexagonal tapered hole at the middle connects the regular hexagonal hole at the upper end and the regular hexagonal hole at the lower end. The structure design of the downcomer 511 can better realize oil-water separation. Figure 9
