Abstract

Technical Field
[0001] The utility model relates to the technical field of cement, in particular to a clinker granulation heat conduction and heat exchange component. Background Art
[0002] In the cement production process, the cooling of clinker is a key link. The traditional cooling method mainly relies on grate coolers to cool the high-temperature clinker to room temperature through forced convection. Although this method is effective, it has problems such as low energy utilization efficiency, large equipment footprint, and high maintenance costs.

The traditional air cooling system directly discharges the hot air into the environment, fails to effectively recover and utilize the heat energy, and causes energy waste. In addition, the equipment is highly complex. The existing air cooling system is usually complex in structure, involving multiple equipment and pipeline connections, and is difficult to install and maintain, which affects the reliability and stability of the system.
