Embodiment Construction
[0019] Figure 1, figure 2 and image 3 As shown: the preheating chamber 1 is in the shape of a square cylinder, with two inner grate plates 11 and two outer grate plates 12, the outer grate plates 12 are placed vertically, and the inner grate plates 11 are placed obliquely, forming two symmetrical spaces for storing materials 13, and a ventilation space 14 with a triangular cross-section is formed between the two inner grate plates 11, and the smoke outlet 15 is arranged on the side of the outer grate plate 12. Inside and outside grate plate 11,12 can be circular hole type grate plate, also can be slotted grate plate (fence shape grate plate), what this example adopted is the circular hole type grate plate. The hot gas coming up from the fluidized pre-calcination chamber 2 enters the ventilation space 14, then passes through the inner and outer grate plates 11, 12 and materials transversely, and is discharged through the smoke outlet 15, the ash collecting hopper 16 and the p...
