[0022] The effect achieved by the entire embodiment 1 is that the first vertical plate 202 and the second vertical plate 203 can separate the aqueous solutions on both sides, and the hot air flow enters the interior of the air inlet duct 204, at which time the internal water can be heated, and when the air flow passes through the electric temperature control valve 205, the temperature of the air flow is measured. When the temperature is higher than the set range value, the air flow enters the circulation pipe 206 and re-enters the air inlet duct 204, at which time the aqueous solution on the left can continue to be heated, and when the temperature is lower than the set range value, the air flow enters the air supply pipe 207 to heat the aqueous solution on the right, at which time the waste heat can be absorbed to a greater extent, reducing the waste of waste heat and utilizing the waste heat to a greater extent.

[0023] Embodiment 2, as Figure 1-3As shown, the surface of the box body 1 is rotatably connected to two rotating rods 3 through bearings, and the surfaces of the two rotating rods 3 are respectively provided with stirring rods 4, and the two stirring rods 4 are connected in the middle by belt transmission, and a motor 5 is installed at the bottom of the box body 1, and the output end of the motor 5 is fixedly connected to one of the rotating rods 3, and a filter plate 6 is provided on the surface of the air inlet box 208, and a sealing door 7 is hinged on the surface of the air inlet box 208 through a hinge, and a through hole connected to the air inlet box 208 is opened on the surface of the box body 1, and two water inlet pipes 9 and water outlet pipes 8 are respectively connected on the surface of the box body 1, and the air inlet duct 204 and the air supply pipe 207 are both spirally arranged, and the air supply pipe 207 is fixedly installed on the surface of the box body 1 and the second vertical plate 203, and the two support plates 201 are fixedly connected to the surface of the box body 1.

[0024] The effect achieved by the entire embodiment 2 is that the stirring device and the belt can stir the internal aqueous solution at the same time to make the water temperature uniform.

At this time, the aqueous solution on the left can continue to be heated. When the temperature is lower than the set range value, the air flow enters the air supply pipe 207 to heat the aqueous solution on the right. At this time, the waste heat can be absorbed to the maximum extent.

The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the fan 209, motor 5 and electric temperature control valve 205 are no longer explained in detail.
