Abstract

The invention relates to a heat pump drying system adopting industrial circulating water as a heat source. The heat pump drying system comprises a drying case, a condenser, a compressor, an evaporator, a throttle and a fan, wherein the drying case is provided with an air inlet and an air outlet. The system further comprises a primary settling pond, a heat recovery pond and a settling pond, wherein a first heat conducting portion is arranged in the heat recovery pond, a second heat conducting portion is arranged in the evaporator, and the condenser is provided with a third heat conducting portion corresponding to the air inlet. The inlet end of the compressor communicates with the outlet end of the first heat conducting portion, and the outlet end of the compressor communicates with the inlet end of the third heat conducting portion. The inlet end of the throttle communicates with the outlet end of the third heat conducting portion, and the outlet end of the throttle communicates with the inlet end of the second heat conducting portion. The outlet end of the second heat conducting portion communicates with the inlet end of the first heat conducting portion. The inlet end of the evaporator communicates with the air outlet, and the outlet end of the evaporator communicates with the air inlet. The heat pump drying system can reduce energy consumption, improve the energy utilization rate and reduce environment pollution.

Description

technical field [0001] The invention relates to a heat pump drying system using industrial circulating water as a heat source. Background technique [0002] In my country, the energy used in drying operations accounts for about 14-35% of industrial energy consumption, and a large number of low-grade heat sources such as industrial wastewater above 5°C are wasted and cannot be rationally utilized. Industrial waste heat belongs to renewable energy, and its rational use can improve energy utilization and reduce power consumption, bringing good social and environmental benefits. [0003] Industrial wastewater is a waste heat energy. The production process of stone mainly includes two processes of cutting and polishing. In order to improve the service life of the tool, production efficiency and product quality, etc., it is necessary to use water to cool the tool and remove grinding debris during the processing process, forming sewage that absorbs a large amount of heat. Howeve...
