Through this arrangement, the rack 853 can move on the support rod 852 more smoothly.

[0027] Here’s how it works:

[0028] First, when in use, the medium inlet channel 6 and the medium outlet channel 7 are connected, so that the cold air flows through the heat exchange plate 2, and the fine desulfurization is introduced from the heat exchange inlet channel 4, passes through the heat exchange plate 2, and then flows out from the heat exchange outlet channel 5;

[0029] Second, when the temperature after heat exchange is high, the heat exchange efficiency needs to be increased, and the electric push rod 855 is started, so that the electric push rod 855 pushes the fixed block 854 to move, and the fixed block 854 moves to drive the rack 853 to move, so that the rack 853 moves along the support rod 852, and the rack 853 moves to drive the gear 851 to rotate;

[0030] Third, when the gear 851 rotates, it drives the adjusting rod 82 to rotate, and when the adjusting rod 82 rotates, it drives the baffle 84 to rotate. By adjusting the position of the baffle 84, the space obstruction of the baffle 84 in the medium inlet channel 6 is changed, thereby changing the flow rate of the gas, thereby enhancing the conversion efficiency and reducing the converted temperature. When the temperature after heat exchange is low, consistent with step 2, the electric push rod 855 is controlled to move in the opposite direction to achieve a callback effect, and the temperature can be quickly adjusted.
