The invention discloses a
waste heat recovery device of an industrial
kiln, and relates to the technical field of industrial
kiln equipment. The device specifically comprises a
kiln body. When the device is used, a heat insulation box, a heat preservation
coating outside the heat insulation box and a heat absorption
pipe are arranged, in a using process of the kiln body, heat dissipated by the kiln body through surface
radiation can be effectively recycled, a
waste heat recovery rate of the kiln body is increased, the cost is saved, the situation that the heat is directly scattered into the
atmosphere to cause climate warming is prevented,
environmental protection is facilitated, after firing is completed, a first control valve and a second control valve are opened, a fan is started, and the fan introduces external
airflow into the heat insulation box via an air conveying
pipe and then introduces the external
airflow out of the heat insulation box via an air outlet
pipe, so that the
cooling speed of the kiln body can be increased, collection of fired objects in the kiln body and next-time
material distribution of the kiln body are facilitated, and the production efficiency of the kiln body is improved.
