[0002] The grate cooler is an important main equipment in the clinker burning system of a cement plant. Its main functions are to cool and convey cement clinker. During the production process, the grate cooler generates a large amount of waste hot air, and at the same time, the waste hot air is doped with a large amount of dust and cannot be directly utilized. The existing method is to use heat exchange equipment and waste heat boilers to recover the heat in the waste hot air. However, due to the presence of dust, the heat exchange equipment is prone to blockage. Especially when the production scale is small or the production process cannot be continuous, the heat exchange equipment cannot operate at full load, and the heat exchange efficiency is low, so the heat in the waste hot air cannot be fully recovered.
