The principle of the air treatment process of the present invention is shown in fig. 7, and is mainly divided into heat recovery, air treatment and CO2And (4) heating circulation. The heat recovery device comprises a total heat exchange core 801, an exhaust fan 802, a fresh air valve 803, a fresh air fan 804, an air return valve 805 and corresponding air ducts. The air treatment device comprises an axial fan 601 and a heat exchanger 602. The heating cycle comprises a closed loop consisting of a compressor, a throttle, an external heat exchanger and a heat exchanger 602, the flowing working medium in the loop being CO2Circulating in a transcritical state, and compared with other Freon heat pump working media, CO2The exhaust temperature is higher, and the heating effect is better. The total heat exchange core 801 is used for heat recovery, and exhaust air with high temperature and high humidity and fresh air with low temperature and low humidity exchange heat in the total heat exchange core. The fresh air valve 803 and the return air valve 805 are respectively used for controlling the opening degrees of the fresh air duct 10 and the return air duct 7, and the exhaust fan 802 and the fresh air fan 804 are used for enabling exhaust air and fresh air to overcome the resistance of the total heat exchange core 801 so as to complete heat recovery.
The drying mode comprises a formaldehyde removing drying mode, an automatic drying mode and a high-efficiency drying mode, and the formaldehyde removing drying mode, the automatic drying mode and the high-efficiency drying mode are switched by controlling the opening and closing of the fresh air valve and the return air valve.
Removing formaldehyde and drying: when the user selects the formaldehyde removal mode, the dried objects are dried by the treated fresh air, and the high-concentration formaldehyde air in the drying box is discharged. The specific working process is as follows:
when the drying device is started in the formaldehyde removal mode, the fresh air valve 803 is fully opened, the fresh air fan 804 is started, and the return air valve 805 is closed. The high-temperature and high-humidity air in the drying box is exhausted from the air outlet 102 above the box body 1 under the action of the air exhaust fan 802 and flows through the air return duct 7And the heat enters the total heat exchange core 801, the heat exchange is carried out between the total heat exchange core 801 and the low-temperature and low-humidity fresh air entering from the fresh air duct 10, and at the moment, the heat of the exhaust air is recovered and is exhausted to the atmosphere through the exhaust air duct 9. The fresh air treated by the heat recovery device enters the heat exchanger 602 and the high-temperature and high-pressure CO under the action of the axial flow fan 6012The steam is subjected to heat exchange, enters the air supply box 5 after reaching the air supply temperature, and enters the drying box through the air supply duct 4.
Automatic drying mode: when a user selects an automatic drying mode, the opening degrees of the fresh air valve and the return air valve can be automatically adjusted according to the real-time temperature and humidity in the drying box, one part of high-temperature and high-humidity air in the drying box is used for exchanging heat with fresh air, the other part of high-temperature and high-humidity air is used for mixing with the fresh air at the outlet of the total heat exchange core, and the mixed air enters the heat exchanger 602 and enters the high-temperature and high-pressure CO under the action of the axial flow fan 6012The steam is subjected to heat exchange, enters the air supply box 5 after reaching the air supply temperature, and enters the drying box through the air supply duct 4.
High-efficient stoving mode: when the user selects the high-efficient stoving mode, the return air valve is opened entirely, and the new trend valve is in the closure state basically, only opens when the device atmospheric pressure is unbalanced. The air in the box body is discharged through the return air duct 7 and then enters the heat exchanger 602 again through the return air valve to react with the high-temperature and high-pressure CO2The steam is subjected to heat exchange, enters the air supply box 5 after reaching the air supply temperature, and enters the drying box through the air supply duct 4.
The planetary wheel type drying rack provided by the invention continuously rotates in the drying process, so that a plate to be dried can be uniformly dried, disturbance can be brought to air in the drying box through the movement of the planetary wheel type drying rack, the temperature in the drying box is promoted to be uniform, and the drying efficiency is further improved.
In addition, the heat recovery module of the present invention recovers sensible heat and latent heat in the exhaust gas discharged from the drying box by the total heat exchanger. Because of the inside formaldehyde that often contains the high concentration of panel, formaldehyde is very fast under the environment of high temperature and high humidity, therefore the stoving in-process, the inside formaldehyde concentration of stoving case is higher, if want to reach the effect of cleaing away this part formaldehyde, needs the exhaust in the stoving case, introduces fresh air. However, the exhaust gas in the drying box has high heat, and if the exhaust gas is directly exhausted to the air, the energy is wasted. Therefore, the heat recovery device is arranged and used for recovering sensible heat and latent heat of the part of waste gas and preheating the part of waste gas for fresh air, so that the energy utilization efficiency can be effectively improved, the aim of saving energy is fulfilled, and the effect of removing formaldehyde is achieved.
