Abstract

The application discloses a waste heat recovery kiln system and belongs to the technical field of industrial kilns. The system comprises a kiln main body and a waste gas treatment furnace. The kiln main body is provided with a three-layer nested structure formed by an inner liner, a heat exchange layer and a heat preservation layer from outside to inside. The tar-containing waste gas generated by the inner liner is introduced into the waste gas treatment furnace through a pipeline for incineration and decomposition. The high-temperature gas flow after purification is introduced into the heat exchange layer to radiantly heat the inner liner. The heat exchange layer is internally provided with a cavity with a first end and a second end connected and with a turning section at the two ends. The waste heat gas forms a scouring flow state with "middle horizontal and two end turning" in the cavity, and a targeted smoke dust treatment port is arranged at the turning section. The application cancels the traditional electric heating element, utilizes clean waste heat closed loop heating, eliminates the short circuit risk caused by tar adhesion, eliminates the air burning and coke removing process, and significantly improves the heat exchange efficiency and the stability of continuous operation of the equipment in combination with the special turning flow channel design.
