As further describing for above-mentioned technical proposal：
The liquid-collecting bin is provided with two altogether, and two liquid-collecting bins are on symmetrical at the vertical centerline of dehumidification pipe.
In the present invention, pass through the deflector of setting first so that, can be along inclining when high-temperature gas flows in warehouse for drying
Oblique deflector uniformly flows downward, so as to increase the contact area of high-temperature gas and heat sink, while the through hole in heat sink
Upper end diameter is more than lower end diameter, can increase high-temperature gas and enter the speed of through hole, and then add the utilization of high-temperature gas
Rate, drying efficiency is further accelerated, secondly by the dehumidification pipe of setting, in the case of without using electric energy, realize gas
The efficient exsiccation of moisture content in body, it is achieved thereby that the drying process of gas, is advantageous to the recycling of heat, while sponge
The structure of adsorption plate inner curved arc, while self-strength is ensured, also increase the contact surface of gas and sponge adsorption plate
Product, so as to accelerate the dehumidification rate of gas.
