The invention relates to the technical field of boiler
heat energy recovery and
energy conservation, in particular to energy-saving equipment for boiler heat
recovery, which is applied to a previous process of
animal fat extraction and preheating equipment and is used for preheating
animal fat raw materials in advance. The equipment disclosed by the invention is named as a
raw material preheating pot and is
animal fat preheating equipment. The device comprises an extraction
barrel, the upper surface of the extraction
barrel is fixedly communicated with a feeding
pipe, and the lower surface of the extraction
barrel is fixedly communicated with a discharging port. The temperature of a boiler
smoke outlet is higher than that of a heat conduction oil boiler outlet, high-temperature
smoke exhausted by a boiler
chimney is used as a heat source to preheat animal fat, serious
thermal pollution caused by the fact that high-temperature gas is directly exhausted into air is avoided, recycling of resources is achieved, and negative effects on the environment are reduced. And
heat transfer is performed through a single-line
communication channel formed by the heat exchange channel and the heat exchange
pipe, so that the problem of non-uniform temperature distribution is effectively avoided, and animal fat can be uniformly preheated.
