Air-conditioning type drying device

Abstract

The invention discloses an air-conditioning type drying device. A water tank is arranged in a heat-insulating enclosure, water is injected into the water tank to immerse a spiral coil A and a spiral coil B in the water tank. A compressor A, the spiral coil A, a capillary tube A and a refrigerating air conditioner internal unit and relevant pipes form a heat pump circulating humidification system A. A heating air conditioner external unit, a heating air conditioner internal unit, a capillary tube B and relevant pipes form a heat pump circulating heating system B. The system A achieves temperature reduction in the heat-insulating enclosure and condensation and discharge of vaporous water and stores heat released through temperature reduction and vaporous water condensation. The system B achieves temperature rise in the heat-insulating enclosure and material moisture vaporization to the heat-insulating enclosure and absorbs the heat stored in the water tank by the system A. The system A and the system B alternatively work to achieve evaporation, condensation and discharge of material moisture in the heat-insulating enclosure and storage and utilization of the heat in the water tank. Compared with an existing gaseous humidification and drying mode, the energy consumption is greatly reduced, and refrigeration, dehumidification and zero heat discharge can be achieved.

Description

technical field [0001] The invention relates to an air-conditioned drying device. Background technique [0002] Drying device is a very widely used equipment, widely used in biology, medicine, chemical industry, agriculture and other fields. The drying process is essentially the process of discharging the moisture in the material. However, almost all of the existing drying equipment uses direct heating to discharge the moisture in the material in the form of gaseous water. Because the enthalpy of gaseous water is much higher than that of liquid water And the temperature is relatively high, so a large amount of energy is also discharged when the gaseous water is discharged, which inevitably causes a large amount of heat energy loss, which is obviously not in line with my country's current energy-saving and emission-reduction policies. [0003] On the other hand, most of the heating methods of existing drying equipment are direct heating, that is, direct heating by steam or el...

The drying process is essentially the process of discharging the moisture in the material. However, almost all existing drying equipment uses direct heating to discharge the moisture in the material in the form of gaseous water. Because the enthalpy of gaseous water is much higher than that of liquid water And the temperature is high, so a large amount of energy is also discharged when the gaseous water is discharged, which inevitably causes a large amount of heat energy loss, which is obviously not in line with my country's current energy-saving and emission-reduction policies

[0003] On the other hand, most of the heating methods of existing drying equipment are direct heating, that is, direct heating by steam or electricity or heat transfer oil, but the thermal conversion efficiency of direct heating is low, and the thermal conversion rate of large boilers can only reach About 90%, while the heat pump heat transfer energy efficiency is relatively high, up to 3 or more, which greatly improves the heat energy utilization efficiency and realizes energy saving and emission reduction
