DETAILED DESCRIPTION

[0029] In order to make the purposes, technical schemes and advantages of the embodiments of the utility model clearer, the technical schemes in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0030] As Figure 1 Indicated, a fluidization device for crystallization granulation, comprising:

[0031] Tower body 1, the inside of tower body 1 is provided with vulcanization space;Tower body 1 bottom is provided with blowdown 6;Tower body 1 upper portion is provided with overflow valve 3;Tower body 1 is installed on support 7;
