Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings. Such as Figure 1-3 A drying room waste heat recovery device shown includes a heat exchange body, which is characterized in that: the heat exchange body includes a shell 1 and a fresh air channel 3 and a hot exhaust gas channel 2 in the shell 1, and the fresh air channel 3 and the hot exhaust gas channel 2 are provided with a heat exchange device 4, which absorbs the heat of the exhaust gas flowing through the hot exhaust gas channel 2 by using the principle of heat exchange.
[0018] Further, the hot exhaust gas passage 2 sequentially includes a hot exhaust gas tank 21 , a heat exchange area 22 and a cooled exhaust gas tank 23 according to the hot exhaust gas flow direction 20 ; the fresh cold air flow direction 30 is opposite to the hot exhaust gas flow direction 20 .
[0019] Further, the hot exhaust gas channel 2 in the heat exchange area 22 is located at the center...
