A sanitary wastewater heat recycling device comprises a water mixing valve, a heat recycling device, a confluence tee joint, an overflow assembly and a wastewater pool. A clear cold water is connectedwith an inlet of the water mixing valve in a communicating manner. A first outlet of the water mixing valve is connected with a water feeding opening of the heat recycling device in a communicating manner. A water discharging opening of the heat recycling device is connected with a first inlet of the confluence tee joint in a communicating manner. The second outlet of the water mixing valve is connected with a second inlet of the confluence tee joint in a communicating manner. The outlet of the confluence tee joint is connected with a water utilization device in a communicating manner. The heat recycling device is arranged in the wastewater pool or constitute the inner surface of the wastewater pool. High-temperature wastewater in the wastewater pool transmits heat to low-temperature clear water through the heat recycling device. The overflow assembly keeps part of newly fed high-temperature wastewater into the wastewater pool. The water mixing valve adjusts the water discharge temperature of the wastewater heat recycling device.
Description
technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a domestic wastewater heat recovery device. Background technique [0002] Currently known heat recovery devices for domestic waste water, such as application number CN201820065590 "A heat exchange waste water pool for waste heat recovery of bath waste water", discloses a heat exchange waste water pool for waste heat recovery of bath waste water, including a pool body and an equipment box and waste heat recovery drum. In this application, a waste heat recovery cylinder is installed inside the pool body. The waste heat recovery cylinder is equipped with a spiral pipe formed by a water connection pipe and a heat transfer pipe. When in use, when the temperature sensor inside the water connection head on the top of the water connection pipe detects If the temperature is higher than the set value, the information will be sent to the controller, and t...
