Abstract

The invention discloses an energy-saving low-carbon sewage source heat pump system utilizing low-grade heat in sewage. The energy-saving low-carbon sewage source heat pump system is characterized in that a self-cleaning heat exchange coil assembly is arranged in a sewage outlet pool of a sewage treatment plant; the self-cleaning heat exchange coil assembly is connected with an evaporator and a condenser of the heat pump subsystem through the control pipe network subsystem and can form an evaporation heat exchange circulation loop with the evaporator and form a condensation heat exchange circulation loop with the condenser. The tail end heat exchange subsystem is connected with an evaporator and a condenser of the heat pump subsystem through the control pipe network subsystem and can form an evaporation heat exchange circulation loop with the evaporator and form a condensation heat exchange circulation loop with the condenser. According to the system, effluent of a sewage plant is utilized, heat is directly exchanged in an effluent pool of the sewage plant through the self-cleaning heat exchange coil assembly, sewage heat can be fully utilized to achieve heating and refrigerating, a primary sewage conveying pump, sewage filtering equipment, primary heat exchange equipment and other equipment are omitted, and the energy efficiency is improved.

Description

technical field [0001] The invention relates to the fields of sewage treatment and energy reuse, in particular to an energy-saving and low-carbon sewage source heat pump system. Background technique [0002] The principle of water source heat pump technology is to convert the low-grade heat energy resources contained in the water source into usable high-grade heat energy by inputting a small amount of electric energy. This method is most in line with the principles of heat source temperature matching, energy cascade utilization, and energy saving and low carbon. At present, water source heat pump heating has become the research focus of energy development in countries all over the world. [0003] Compared with other energy sources, the urban sewage treated by the sewage treatment plant is a rare cold and heat source for heat pumps. Its water quality and temperature are relatively stable throughout the year, and the water output is large. The annual temperature is 10-25°C, a...
