[0094] Example 2

[0095] like Figures 10-18 As shown, this embodiment provides a horizontal heat exchanger supported by an ear seat, which, based on embodiment 1, further includes the following configuration:

[0096] In this embodiment, d = 832.5 mm, the total length of the horizontal heat exchanger is 1980 mm, the tube-side lug bolt hole 4-2-1 is connected to the M20 bolt, and the shell-side lug bolt hole 5-2-1 is connected to the M20 bolt to support the horizontal heat exchanger.

[0097] The reason for the ear-type design in the shell side is that the allowable shear stress of the two anchor bolts is insufficient to withstand the pulling force of the tube bundle during tube bundle pull-out, requiring four bolts. However, the length of the shell body 2 is constrained by the length of tube bundle 6, leaving no space in the shell side to accommodate two separate ear-type anchor bolts. The formula for calculating the shear force σ borne by the anchor bolts is σ=(Ng-F μ ) / (S*n), where Ng is the pulling force of the tube bundle 6, F μ S represents the static friction force of the horizontal heat exchanger, S represents the effective cross-sectional area of ​​a single anchor bolt, and n represents the number of anchor bolts. Furthermore, because the horizontal heat exchanger will experience horizontal displacement due to temperature changes, the anchor bolt holes are Φ30 larger than normal.

[0098] The design idea of the horizontal heat exchanger supported by the lug support is:

[0099] After the rest of the pressure components are calculated, the total weight m of the heat exchanger is estimated first. Referring to NB / T47065.3-2018 Appendix A, the approximate load Q borne by the lug support of the horizontal heat exchanger is obtained. For this heat exchanger, the shell side lug support 5 bears not only the weight of the heat exchanger, but also the horizontal pulling force F of the tube bundle 6, and the gravity load borne by the shell side lug support 5 and the tube side lug support 4 can be obtained by the lever principle, that is, Q1=mgd2 / (2d)+Fh / (2d1), wherein d is the horizontal distance between the gravity centers of the tube side lug support 4 and the shell side lug support 5 on the same side, d=d1+d2, d1 is the horizontal distance between the gravity center of the horizontal heat exchanger and the gravity center of the shell side lug support 5, d2 is the horizontal distance between the gravity center of the heat exchanger and the gravity center of the tube side lug support 4, and h is the vertical distance from the gravity center of the heat exchanger to the lower surface of the shell side lug support bottom plate 5-2. And the tube side Q2=mgd1 / (2d). The rest of the calculation can refer to NB / T47065.3-2018 Appendix C, so as to obtain reasonable sizes and thicknesses of various accessories.

[0100] The above description of the embodiments is for the convenience of the ordinary skilled person in the art to understand and use the utility model. Those skilled in the art can obviously make various modifications to these embodiments easily, and apply the general principles described herein to other embodiments without creative labor.
