Description

Technical Field

[0001] The utility model relates to the technical field of decomposition furnaces, in particular to a high-efficiency decomposition furnace for cement clinker production. Background Art

[0002] Cement is a powdery hydraulic inorganic cementitious material. It becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly cement materials such as sand and stone together. The decomposition furnace is a very important equipment in the pre-decomposition system of cement production. It is usually installed at the tail of the rotary kiln. It undertakes the heavy tasks of fuel combustion, heat exchange and carbonate decomposition in the pre-decomposition system. The basic working principle of the decomposition furnace is: preheated raw meal, a certain amount of fuel and an appropriate amount of hot gas are fed into the decomposition furnace at the same time, and the raw meal is suspended or boiling in the furnace. The raw meal and fuel are fully dispersed and mixed in the furnace. The fuel burns rapidly in the furnace and transfers the combustion heat to the raw meal in time, so that the carbonate components in the raw meal quickly absorb heat and decompose.

[0003] The existing Chinese utility model patent with reference announcement number: CN217275490U discloses a new type of decomposition furnace for cement production. The utility model includes a preheating box arranged at the upper end of the decomposition furnace body, the bottom side of the decomposition furnace body is connected with a discharge pipe, the upper side of the preheating box is provided with a guide hopper, one end of the preheating box is provided with a feeding mechanism connected with the guide hopper, the inner wall of the preheating box is provided with a smoke cavity, and the two ends of the inner cavity of the preheating box are symmetrically fixed with guide inclined plates. The guide inclined plates at both ends are staggered and inclined downward, a heat conduction cavity is formed inside the guide inclined plates, and the heat conduction cavity is connected with the smoke cavity; the hot smoke is introduced into the smoke cavity of each guide inclined plate along the heat conduction cavity, and the raw material is transported to the guide hopper through the feeding mechanism and introduced into the preheating box, the raw material contacts the guide inclined plates for preheating, and falls downward along the inclined angle, and the raw material is dispersed at the same time, which not only improves the preheating quality of the raw material, but also increases the preheating rate of the raw material and improves the decomposition time of the cement.

[0004] The existing decomposition furnace is used for processing cement clinker, and the outlet temperature of the decomposition furnace is relatively high. At the same time, the outlet of the decomposition furnace and the outlet of the cyclone are connected and used in coordination to achieve the discharge efficiency. However, there is a serious temperature inversion between the outlet of the decomposition furnace and the discharge pipe, which affects the production efficiency of cement clinker, reduces the practicality of the decomposition furnace, and reduces the processing efficiency of cement clinker.
