The invention discloses an intelligent high temperature heat pump drying system with damp-heat recovery. The system comprises a high temperature heat pump subsystem, a damp-heat recycling subsystem, a temperature and humidity control adjusting subsystem and a house drying subsystem. The intelligent high temperature heat pump drying system with damp-heat recovery organically combines the high temperature heat pump technology, the air-condition adjusting technology, the waste heat recycling technology with the assistant electric heating technology, the application field of drying of different materials is broadened, and the reliability, the stability and the economy of the operation of the high temperature heat pump drying system are improved; according to the intelligent high temperature heat pump drying system with damp-heat recovery, through the intelligent adjustment of a controller PLC and related execution mechanisms, for the requirement of a material drying technology, a time-interval temperature and humidity control strategy is adopted, the full-automatic control of the drying process is achieved, meanwhile, the character, the color and the fragrance of dried materials are improved, and the quality of the dried materials is guaranteed; according to the intelligent high temperature heat pump drying system with damp-heat recovery, the waste heat of humidity elimination is recycled through a damp-heat recycling heat exchanger, the cost performance is high, and the energy conservation and the environment protection are achieved.

Description

technical field [0001] The invention relates to an intelligent high-temperature heat pump drying system with damp heat recovery. Background technique [0002] In my country, the traditional drying technology mainly uses primary energy such as fuel oil, gas, coal or wood to generate heat for product drying. Harmful substances such as acid rain, smog and other disasters are caused, which seriously pollute the environment. At the same time, using traditional energy drying technology, during the drying process of materials, harmful gases will enter the drying room, causing harmful substances such as sulfur to be contained in the materials, forming secondary pollution. Therefore, the traditional drying process needs to be improved. [0003] There are two main types of new drying technologies at present. One is the direct heating technology of electric heating tubes, which is simple to operate, but the efficiency is too low and the operating cost is high, which is contrary to the...
