Document Type and Number:
Japanese Patent JP2013525729
Kind Code:
A
Abstract:
Method for extracting heat from an effluent flowing in a duct (2), in particular a wastewater collection device. In said method, a heat exchanger (E) that is submerged in the effluent is mounted at least on the bottom of the duct, the heat exchanger (E) being formed by coating tubes (3) with a material that is sufficiently heat-conducting, is poured around the tubes, and hardens in situ. A heat transfer fluid flows in the tubes (3), the heat being transferred from the effluent in the duct through the molded coating, the upper surface of the poured material being in direct contact with the effluent flowing in the duct, but not with any inserted mechanical part.; The coating is composed of multiple layers having different material properties, i.e. a layer (9) of heat insulation material between the tubes (3) and the wall of the duct (2), a layer (10) of heat conducting material between the tubes and the effluent, in contact with the tubes, and an abrasion-resistant layer (11) on the surface, in contact with the effluent.
