Waste heat recovery heat exchanger for household bathroom waste water

Abstract

The invention discloses a household bathroom wastewater waste heat recycling heat exchanger. The household bathroom wastewater waste heat recycling heat exchanger comprises a water collection filter, a plurality of layers of copper plates, water discharging openings, temperature control valves, angular copper bars, a plurality of horizontal heat exchange tubes, a U-shaped tube, a rubber tube and a waste heat recycling heat exchange box body, wherein the water collection filter is arranged at a top of the waste heat recycling heat exchange box body; all the copper plates are transversely mounted in the box body in parallel; the plurality of horizontal heat exchange tubes are fixed on upper parts of the copper plates through the angular copper bars; heat conduction oil is filled in gaps between the horizontal heat exchange tubes and the angular copper bars; two ends of the angular copper bars are sealed by the oil conduction oil; refrigerants are filled in the horizontal heat exchange tubes; the water discharging openings are formed in the copper plates; the water discharging openings of two adjacent layers of copper plates are formed in two opposite sides respectively; and the temperature control valves are mounted under the water discharging openings. According to the household bathroom wastewater waste heat recycling heat exchanger, heat exchange efficiency of the heat exchanger is not influenced; meanwhile, heat exchange parts in the heat exchanger are washed conveniently; and prominent effect in application of a bathroom wastewater heat pump can be achieved.

Description

【Technical field】 [0001] The invention relates to a waste heat recovery heat exchanger for domestic bathroom waste water. 【Background technique】 [0002] At present, my country's heating methods mainly include several conventional heating methods such as coal, oil, gas, electric heating, and solar energy. With the development of the economy, the shortage of resources has increasingly become the main obstacle restricting social development; with the advancement of science and technology, the development and application of environmentally friendly and energy-saving products are constantly pursued, and the use of energy-saving and environmentally friendly hot water supply products is the current mainstream. [0003] The temperature of the waste water after human body bathing is about 30-32°C, and heat recovery for this waste water is a good way to save energy. The current products include bathroom wastewater heat pump technology. This technology uses shower wastewater with hig...
