Embodiment 1
[0034] Such as Figure 2 to Figure 6As shown, the kettle body 1 of the vacuum rotary reactor c includes an insulation layer 1a and a kettle wall 1b, the insulation layer 1a is located on the outer wall of the kettle body 1, and the kettle wall 1b is located inside the kettle body 1 and extends into the inner cavity of the kettle body to form a plurality of Uniform setting is used to increase the contact area with the inner layer of the kettle body and to stir the stirring ribs 6 for agricultural and forestry waste. The stirring ribs 6 are distributed in multiple sections, and the height of the stirring ribs is 1 / 3 of the radius of the kettle body. All the stirring ribs 6 The direction of installation is the same and it is arranged at a certain angle with the axial direction of the rotating shaft of the kettle body. Among them, the angle α between the stirring edge 6 and the axial direction of the rotating shaft of the kettle body 1 ranges from 20 to 30°. The included angle β b...
Embodiment 2
[0039] The difference from Embodiment 1 lies in the setting of the heat pipe, such as Figure 7 As shown, the kettle wall 1b of the kettle body 1 extends into the inner cavity of the kettle body 1 to form a plurality of stirring ribs 6 that are evenly arranged to increase the contact area with the inner layer of the agricultural and forestry waste in the inner cavity of the kettle body and facilitate stirring of the agricultural and forestry waste. The height is 1 / 3 of the radius of the kettle body, and the outside of the kettle wall 1b and the stirring edge 6 are evenly arranged along the axis of the kettle body 1. There are a plurality of heat conduction pipes 7 that directly contact and heat the agricultural and forestry waste in the inner cavity of the kettle body 1, and the kettle body The heat-conducting tubes 7 in the body 1 are divided into multiple heating sections along the direction of use, and the axial coils formed by connecting the heat-conducting tubes 7 in each ...
Embodiment 3
[0041] The difference from Embodiment 1 is that, as Figure 8 to Figure 10 As shown, there is an integrated cavity X for the flow of superheated steam in the kettle wall 1b and the stirring edge 6, and the cavity X in the kettle wall 1b and the stirring edge 6 communicates with a rotary joint 8a, and the rotary joint 8a is connected to the The input hose 10a is connected, and the rear side of the kettle body is provided with a heat source part that supplies superheated steam to the cavity X in the kettle wall 1b and the stirring edge 6 by the input hose 10a. In this embodiment, the heat source part (in the figure The heat transfer medium not shown) is superheated steam, and the still body is also provided with a steam trap 15 that communicates with the cavity X in the still wall 1b and the stirring edge 6 so that the condensed water in the cavity is discharged.
