1results about How to "Avoid wasting heat" patented technology

The utility model relates to wastewater multistage filtering device, including the first filtering component for carrying out primary filtration to wastewater, the right -hand member of first filtering component is equipped with the second filtering component for carrying out fine filtration to wastewater, the right -hand member of second filtering component is equipped with the heat exchange component for carrying out waste heat recycling to the wastewater after filtering, first filtering component, second filtering component and heat exchange component intercommunication between them. The utility model discloses through first filtering component can carry out primary filtration and middle filtration to wastewater, through setting up second filtering component, can carry out fine filtration to the bathing wastewater after filtering through first filtering component with quartz sand filter material etc, thereby realizes multistage filtration to wastewater, and the filtering effect is better than traditional device, and through setting up heat exchange component, can make full use of the waste heat in bathing wastewater, can realize the secondary use to waste heat, thereby avoid causing the waste of heat in bathing wastewater, more energy -conserving environmental protection.
