Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a decomposition furnace with an optimized material spreading platform structure. Background Art

[0002] The decomposition furnace is a new type of thermal equipment that simultaneously carries out fuel combustion, heat exchange and decomposition reaction. Its basic principle is to feed preheated raw materials, a certain amount of fuel and an appropriate amount of hot gas into the decomposition furnace at the same time. The raw materials are suspended or boiling in the furnace, and the fuel is flamelessly burned at a temperature below 900°C. At the same time, the heat transfer and calcium carbonate decomposition process are completed at high speed. This process takes about 2 to 4 seconds. The decomposition rate of calcium carbonate in the raw materials can reach 85% to 95%. For this purpose, a decomposition furnace with an optimized spreading platform structure is proposed.

[0003] An existing Chinese utility model patent with reference number CN208588243U discloses a distributing device for a decomposition furnace, belonging to the field of cement production technology. This technical solution includes a decomposition furnace body and a fixed frame. A silo is provided at the top of the inner walls on both sides of the fixed frame. A first filling block and a second filling block are provided on either side of the inner wall bottom of the silo. A discharge pipe is connected to the lower surface of the silo, and a first discharge pipe is fixedly mounted on the end of the discharge pipe away from the silo. A second discharge pipe is fixedly mounted on the end of the first discharge pipe away from the discharge pipe. A fixing member is fixedly mounted in the middle of the upper surface of the decomposition furnace body. A third discharge pipe is provided between the second discharge pipe and the fixing member. A crossbar is fixedly mounted on the interior of the fixed frame near the third discharge pipe. In this utility model, the distributing device can improve the utilization rate of raw materials, enable the movable feeding of the distributing plate, drive the distributing plate to rotate in the horizontal direction, and improve the uniformity of the incoming materials. The structure is novel and has excellent practicality.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it was found that since the position of the tertiary air duct in the current decomposition furnace is at the junction of the cone and the straight cylinder, it affects the uniformity of the combustion and decomposition process, and the existing spreading platform is located at a low position, the material is unevenly dispersed, and the preheating effect is poor. The existence of these problems has affected the use of the device. Utility Model Content
