Example Embodiment

[0010] Examples:

[0011] Such as figure 1 with figure 2 As shown, this embodiment describes a drying equipment using a sealed negative pressure air supply system, which includes an airtight storage body 1, characterized in that a storage door 2 is provided on the airtight storage body 1 , The air-tight storage body 1 constitutes a heat treatment area 3 and a drying area 4. The heat treatment area 3 is provided with a heat exchanger 5, the lower part of the heat exchanger 5 is provided with a fan 6, and the drying area 4 A pipe 7 connected to the heat treatment area 3 is set. In practical applications, the fan 6 relies on the input mechanical energy to increase the gas pressure and send the gas to the heat exchanger 5, and the cooling gas passing through the heat exchanger 5 is driven by the gas pressure. Circulate through the pipeline 7 back to the drying area 4; the air-tight storage body 1 is provided with a rotary dehumidification device 8, and both ends of the rotary dehum...

Abstract

The invention discloses drying equipment applying a sealed negative pressure air supply system, which comprises a sealed library body, wherein a library door is arranged on the sealed library body, the sealed library body comprises a heat processing region and a drying region, a heat exchanger is arranged in the heat processing region, a draught fan is arranged under the heat exchanger, a pipeline is arranged in the drying region and is connected with the heat processing region, a rotary dehumidification device is arranged outside the sealed library body, and the two ends of the rotary dehumidification device are respectively provided with the heat processing region and the drying region. Since the heat processing region, the drying region, the rotary dehumidification region and the sealed library body are arranged, air circulation adopts an air suction form, and air forms a negative pressure region by resistance loss of the heat exchanger and a pipeline. Compared with the traditional drying equipment, the drying equipment has the advantages that the ideal effects of reducing air relative humidity, dew point temperature and steam partial pressure, and drying a material can be achieved.

Description

technical field [0001] The present invention relates to a drying device, more specifically to a drying equipment using air circulation. Background technique [0002] In the field of drying equipment, all kinds of drying equipment using air circulation are generally positive pressure air supply. Due to the sealing of the equipment, the absolute pressure must be higher than the ambient atmospheric pressure. Positive pressure air supply will increase the relative humidity, dew point temperature, and water vapor partial pressure of the same moisture content, which is not conducive to the transfer of water molecules inside the dry material and the evaporation of water vapor on the surface of the material, resulting in a decrease in drying speed. The problem of reducing and increasing the moisture content inside the dry material. Contents of the invention [0003] The object of the present invention is to provide a drying equipment using a sealed negative pressure air supply sy...
