Abstract

The invention relates to a hydraulic high-temperature heat supply heat pump system for recovering waste heat, which includes a waste heat recovery system, a hydraulic high-temperature heat supply heat pump system and a solar energy auxiliary heating storage system. The waste heat recovery system includes waste heat inlet pipelines in fluid communication in sequence , evaporator and waste heat return pipeline; hydraulic high temperature heat supply heat pump system includes liquid storage tank, circulation pump, evaporator, water vapor compressor, condenser and liquid collection tank, liquid storage tank, circulation pump and evaporator The liquid storage tank, the steam compressor, the condenser and the liquid collection tank are fluidly connected in turn to form a second fluid circulation circuit; wherein the liquid collection tank is in fluid communication with the water vapor compressor for Feed condensate to the steam compressor. The liquid collecting tank of the invention can automatically compensate the water vapor compressor, and can introduce solar energy to heat the waste heat liquid when the waste heat is insufficient.

Description

technical field [0001] The present application relates to the technical field of heat pump energy saving, in particular to a hydraulic high-temperature heat supply heat pump system for recovering waste heat. Background technique [0002] The heat pump system is an efficient energy-saving system. Its use can effectively recover low-grade energy, improve energy utilization efficiency, reduce the consumption of high-grade energy, and relieve the pressure of the energy crisis. Therefore, the heat pump system has been respected by all walks of life. It has been widely used in social production and life. However, as a system that requires a large amount of circulating working fluid, the heat pump system also faces the problem of selecting the circulating working fluid. Traditional chlorofluorocarbon synthetic working fluids have seriously damaged the ozone layer, and the greenhouse effect is obvious. The future use and development are obviously restricted, which makes the selecti...
