In this embodiment, a drain pipe 2011 is disposed at the bottom of the casing 201, and a water pan 8 is disposed below the drain pipe 2011 to prevent the condensed water in the fresh air heater 2 from being scattered everywhere.
The outer preheating drying device provided by the embodiment has the following working procedures:
firstly, a booster fan 7 in the booster area 1052 is started to drive the air in the drying cavity 105 to flow out through a heat flow channel of the fresh air heater 2; negative pressure is formed in the drying cavity 105;
secondly, under the negative pressure action of the drying cavity 105, fresh air in the outer space enters the dehumidifying cavity 106 through the air inlet 1061 of the room body 1, the humidity of the fresh air is reduced under the action of the dehumidifier 5 and the drying agent 6, and then the fresh air enters the cold flow channel through the fresh air inlet 2031 of the fresh air heater 2; after absorbing heat in the cold flow channel, the temperature of the fresh air rises, and then the fresh air enters the return air channel 1051 through the fresh air outlet 2041;
thirdly, after passing through the condensing assembly 302, the air in the air return channel 1051 is heated to become hot air, and then enters the pressurizing area 1052;
fourthly, the booster fan 7 blows hot air in the booster area 1052 to the water-containing product 4, the hot air absorbs water vapor in the water-containing product 4, and the water-containing product 4 becomes hot air with higher humidity after being dried;
hot air with higher humidity enters the hot air channel through the hot air inlet 2051, after heat is released to the fresh air in the cold air channel, the temperature is reduced to realize the first waste heat recycling, and then the hot air leaves the fresh air heater 2 through the hot air outlet 2061;
sixthly, hot air leaving the fresh air heater 2 blows to the evaporation assembly 301 to provide heat for the evaporation assembly 301, so that the power consumption of the heating device 3 is reduced, and secondary waste heat recycling is realized.
The external preheating drying device provided by the embodiment at least has the following advantages:
firstly, the fresh air heater 2 is arranged externally, so that the problem of corrosion of condensed water is avoided; and is beneficial to the discharge of condensed water without affecting the internal humidity of the drying cavity 105;
no V-shaped groove 1041 is needed, so that the assembly process is simplified, and the production efficiency is improved;
the hot air leaving the fresh air heater 2 is directly blown to the evaporation assembly 301, so that the energy utilization efficiency is improved;
and fourthly, the fresh air entering the fresh air heater 2 is dried and dehumidified, and the drying effect in humid weather such as plum rain seasons is improved.
