[0001] This utility model relates to the technical field of wastewater waste heat recovery and utilization devices, and in particular to a wastewater waste heat recovery and utilization device. Background Technology

[0002] Wastewater heat recovery is a technology with significant economic and environmental benefits. By recovering heat energy from wastewater, energy consumption, carbon emissions, and operating costs for enterprises can be effectively reduced. Wastewater heat recovery is mainly based on heat exchange technology, which uses equipment such as heat pumps and heat exchangers to transfer heat energy from wastewater to other media that need to be heated.
