[0018] The present invention will be further described below in conjunction with the drawings. Such as figure 1 As shown, a drying room waste heat recovery device includes a box body 1 and a heat exchange device, the heat exchange device is combined with the box body 1 through a heat exchange coupling member 2, and cold air is pumped into the heat exchange device, The heat exchange principle is used to absorb the heat of the exhaust gas flowing through the box 1.
[0019] Further, the heat exchange device is located on the upper part of the heat exchange joint 2, and includes a blower 3, a preheating chamber 6 and an air outlet joint joint 5, which is used to circulate the air that absorbs the residual heat; the box body 1 is located on the heat exchange joint 2. At the bottom of the box, an exhaust fan 4 is provided on one side of the box for the circulation of waste heat gas; the blower 3 and exhaust fan 4 are controlled by frequency conversion; inside the box 1, there are 4 e...
