DEVICE FOR RECOVERING HEAT FROM WASTEWATER, THERMAL SYSTEM INCLUDING SUCH A DEVICE, AND METHOD.

摘要

The invention relates to a heat recovery device (6), including a vat (18) for storing wastewater and a heat exchanger (20) including at least one heat exchange plate (60) including two opposite surfaces (62) and an inner pipe (64) for the circulation of a coolant between the two surfaces (62). According to one aspect of the invention, the or each plate (60) is arranged in a heat exchange compartment (46) of the vat (18) such that the wastewater flows substantially vertically from the bottom upward along the two opposite surfaces (62) of the or each plate (60) between an inlet (54) of the heat exchange compartment (46) located in the lower portion and an outlet (40) of the heat exchanger compartment (46) located in the upper portion. The invention can be used in thermal systems with a heat pump.
