带有储热装置的热泵干燥系统及其工作方法
摘要：
本发明公开了一种带有储热装置的热泵干燥系统及其工作方法，属于节能领域。该系统包括干燥装置、高温储热器、低温储热器、低温蒸发器、高温蒸发器、压缩机、高温冷凝器、低温冷凝器、节流阀、低温储热装置、高温储热装置；在热泵干燥装置中，使用非共沸工质将干燥装置所得的高温湿空气经两次蒸发和两次冷凝，减小了冷凝器和蒸发器的传热不可逆损失使循环的效率得以提高，充分回收利用余热，达到节能的目的。并且在系统中加入储热装置，使得干燥过程产生的有毒和腐蚀性流体不会进入干燥系统，保证系统稳定安全运行。
摘要（英）：

The invention discloses a heat pump drying system with a heat storage device and a working method of the heat pump drying system, and belongs to the field of energy saving. The system comprises a drying device, a high-temperature heat storage unit, a low-temperature heat storage unit, a low-temperature evaporator, a high-temperature evaporator, a compressor, a high-temperature condenser, a low-temperature condenser, a throttle valve, a low-temperature heat storage device and a high-temperature heat storage device. In the heat pump drying device, non-azeotropic working media are used for carrying out two times of evaporation and two times of condensation on high-temperature damp air obtained by the drying device, irreversible losses of heat transfer of the condensers and the evaporators arereduced, the circulation efficiency is improved, waste heat is fully recycled, and the aim of energy saving is achieved. The heat storage devices are added into the system, poisonous and corrosive fluid generated in the drying process cannot flow into the drying system, and it is guaranteed that the system operates stably and safely.
