[0027] The above-mentioned spray drying tower top structure 100, by setting two main support structures 10, each main support structure 10 includes half wind machine 11 and first tower top part 12 arranged on half wind machine 11, so that each main support structure 10 can have smaller size to be transported to the site, it is convenient to be transported to the installation site after higher precision assembly outside the site, and simultaneously including two second tower top parts 20, each second tower top part 20 can also have smaller size, and is transported to the installation site after higher precision assembly outside the site, and then is assembled with two first tower top parts 12 one by one, in this way, not only the assembly of the whole spray drying tower top structure 100 is facilitated, but also the assembly precision of the whole spray drying tower top structure 100 is improved.
[0028] Please refer to Figure 1 AndFigure 2 In one embodiment of the present application, when assembling the two first tower top parts 12, the side of the two first tower top parts 12 facing each other is provided with a third flange plate 13, and the two third flange plates 13 are connected by a second bolt 40. In this way, by providing the third flange plate 13, the two first tower top parts 12 are spliced, and the connection between the two half air separators 11 is also achieved.
[0029] Please refer to Figures 3 to 5 In one embodiment of the present application, when assembling the two first tower top parts 12, the side of the two first tower top parts 12 facing each other is provided with a third flange plate 13, and the two third flange plates 13 are connected by a second bolt 40. In this way, by providing the third flange plate 13, the two first tower top parts 12 are spliced, and the connection between the two half air separators 11 is also achieved.
