Example Embodiment

[0052] Example one

[0053] This embodiment provides an energy-saving hot air drying system 100, please refer to figure 1 , figure 2 , image 3 as well as Figure 4 The energy-saving hot air drying system 100 includes:

[0054] Air supply duct 110;

[0055] The exhaust duct 150 is connected with an exhaust fan 152, and the exhaust fan 152 is used to discharge the gas in the exhaust duct 150 to the outside environment;

[0056] Connecting pipe 120, one end of the connecting pipe 120 is connected with the air supply pipe 110, and the other end is connected with the exhaust pipe 150;

[0057] A plurality of drying units 140, one end of the plurality of drying units 140 is all connected with the air supply duct 110, and the other end is all connected with the exhaust duct 150;

[0058] The drying unit 140 includes: a drying box 141 and an air supply fan 143, the air supply fan 143 is connected to the drying box 141, and the air supply fan 143 is used to discharge the gas in the air supply ...

Example Embodiment

[0094] Example two

[0095] This embodiment provides an energy-saving hot air drying method, which includes the following steps:

[0096] According to the feedback value of the first pressure sensor 111, the frequency of the booster fan 122 is adjusted to make the air supply duct 110 in a slight negative pressure state.

[0097] Adjust the opening of the exhaust valve 144 to the maximum, and gradually increase the frequency of the exhaust fan 152 until all the drying boxes 141 are in a negative pressure state. At this time, read the feedback pressure value of the second pressure sensor 151, and adjust The frequency of the exhaust fan 152 makes the exhaust duct 150 always approach this pressure value.

[0098] The opening degree of the exhaust valve 144 is adjusted one by one, so that the air pressure inside each drying box 141 is in a slight negative pressure state.

[0099] Among them, the slightly negative pressure state is that the relative pressure is between -100Pa and 0Pa.

Abstract

The invention provides an energy-saving hot air drying system and an energy-saving hot air drying method, and belongs to the field of drying devices. The energy-saving hot air drying system comprisesan air supply pipeline, an exhaust pipeline, a communicating pipe and a plurality of drying units, wherein the exhaust pipeline is connected to an exhaust fan, one end of the communicating pipeline communicates with the air supply pipeline, and the other end of the communicating pipeline communicates with the exhaust pipeline; and one ends of the drying units communicate with the air supply pipeline, and the other ends of the drying units communicate with the exhaust pipeline. The energy-saving hot air drying method comprises the following steps that the frequency of a booster fan is adjustedto enable the air supply pipeline to be in a micro-negative pressure state; and the frequency of the exhaust fan and the opening degree of an exhaust valve are adjusted, so that the air pressure inside each drying box is in a micro-negative pressure state. The energy-saving hot air drying system and the energy-saving hot air drying method can be stopped when partial drying units do not need to work, so that the energy consumption can be reduced.
