Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a waste hot water filtering and heat energy recovery device. Background Art

[0002] In modern industrial production and manufacturing, high-temperature wastewater is used in many steps. However, after use, in order to avoid wasting water resources, the hot water is filtered and recycled.

[0003] The traditional recycling method is to filter out the silt and impurities in the wastewater and then recycle it. After using it for a period of time, the filter box needs to be removed to clean the filtered silt, which is quite troublesome. In addition, it only filters the hot water, resulting in the heat loss of the hot water not being well recovered. Therefore, we propose a waste hot water filtration and heat energy recovery device.
