Specifically, the gas enters from the gas inlet 102 and is discharged from the gas outlet 103, and the gas outlet 103 and the gas inlet 102 are arranged at the same end of the shell 106, so that the residence time of the gas in the dehumidifying chamber 101 can be increased; at the same time, the condensed water inlet 104 and the air outlet 103 are arranged along the diagonal line of the casing 10, and the contact time of the condensed water and the air is improved.

According to some embodiments of the present invention, referring to fig. 7 and 8, a first included angle is formed between each baffle 20 and the lower surface of the dehumidifying chamber 101. Specifically, considering that the existence of the plurality of guide plates 20 can reduce the flow rate of the condensed water, the first included angle is formed between the guide plates 20 and the horizontal plane, namely the guide plates 20 are inclined downwards, so that the flow rate of the condensed water is increased, heat can be taken away in time, the heat exchange efficiency is ensured, and the dehumidification capacity is improved. Meanwhile, the water residue is reduced, so that condensed water can flow into the condenser 400 along the flow channel conveniently, and the utilization efficiency of the condensed water is improved.

According to some embodiments of the invention, referring to fig. 7 and 8, the first included angle is α1, where 0 degrees ε1 and 5 degrees. When the first included angle α1 formed between the deflector 20 and the horizontal plane is smaller than 5 degrees, the flow rate of the condensed water is slower, which is unfavorable for timely taking away heat. When the angle is greater than 5 degrees, the water velocity is too fast, and steam contact time is shorter, leads to steam heat transfer time to reduce, can't fully carry out the heat transfer, influences exhaust gas's temperature. Therefore, by setting the first included angle α1 within this range, the flow rate of the condensed water on the deflector 20 can be kept within a proper range at all times without being excessively fast or slow, which is advantageous in ensuring the heat exchange effect. It should be noted that, the first included angle α1 may be any angle between [0,5], for example, α1 may be 0 degrees, may be 2.5 degrees, or may be 5 degrees.

In summary, by arranging the elongated spray opening 107a on the spray plate 1072, and arranging the spray opening 107a opposite to the baffle 20, the condensed water flows from the spray opening 107a to the baffle 20, meanwhile, a plurality of diversion trenches 201 are arranged on the baffle 20 side by side, the initial end 202 of the diversion trench 201 corresponds to the spray opening 107a, the diversion trench 201 is provided with the diversion hole 2011, the condensed water flowing down from the spray opening 107a flows to the initial end 202 of the diversion trench 201 and flows into the diversion trench 201 of the lower layer baffle 20 along the diversion trench 201, and meanwhile, the condensed water flows out in the diversion hole 2011, so that the water-air heat exchange area is further increased; thereby increasing the heat exchange performance of the dehumidifying apparatus 100 and further improving the cooling and dehumidifying capacity of the dehumidifying apparatus 100. The water-climbing phenomenon can be effectively restrained by arranging the spray holes 107a on the spray plate 1072 into a plurality of spray holes and arranging the convex parts 10724 below the spray holes, the condensed water can be ensured to smoothly flow onto the guide plate 20 from the plurality of spray holes, the guide plate 20 is provided with a plurality of guide grooves 201 which are arranged side by side, the diversion trench 201 is provided with a diversion hole 2011, condensed water flowing down from the spraying hole and the bulge 10724 below the spraying hole flows into the diversion trench 201 and flows into the diversion trench 201 of the lower layer diversion plate 20 along the diversion trench 201, and meanwhile, the condensed water also flows out of the diversion hole 2011, so that the water-steam heat exchange area is further increased; thereby increasing the heat exchange performance of the dehumidifying apparatus 100 and further improving the cooling and dehumidifying capacity of the dehumidifying apparatus 100.
