Abstract
Description
Technical Field
[0001] The utility model provides a split type cement kiln heat dissipation device, belonging to the technical field of rotary kiln cooling devices. Background Art
[0002] Cement is a widely used building material. It is a hydraulic cementitious material obtained by grinding and mixing calcareous raw materials (such as limestone), clay raw materials and a small amount of corrective raw materials such as iron ore in appropriate proportions, and then calcining them at high temperature until they are partially melted. Its basic characteristics are that it can harden after adding water, and can continue to harden in air or water, and finally reach a very high strength. Cement kiln is a continuous hot section equipment that can calcine at high temperature to prepare cement clinker in cement production. Cement kiln mainly converts cement raw materials into cement clinker through the three core functions of thermochemical reaction, combustion, heat transfer and material transportation. It is one of the core equipment in cement production.
[0003] At present, cement plants mainly use rotary kilns to make cement. After the raw materials enter the rotary kiln, they become clinker with a temperature of up to 1300 degrees. After the clinker leaves the rotary kiln, it needs to be cooled to 200 degrees on the clinker bed before it can be stored. However, the current rotary kilns are all set up outdoors. During operation, the kiln wall naturally dissipates heat. Therefore, it relies on the ambient temperature difference and air circulation. The cooling rate is slow and sometimes cannot meet the rapid cooling requirements, which prolongs the turnover time of the kiln. In addition, natural heat dissipation will affect the environment and cause the temperature to rise, which will affect the surrounding ecology, residents, and employee health. Utility Model Content
