Abstract

See full text

An energy-saving system using electric heat pump to recover flue gas waste heat for district heating uses flue gas waste heat recovery tower to absorb the sensible and latent heat in the high-temperature flue gas by direct contact heat and mass transfer. The circulating water is sprayed from the top and the flue gas flows upwards in the tower. The electric heat pump is indirectly connected with circulating water through the anti-corrosion and high-efficiency water-water plate heat exchanger. The return water of the heat-supply network enters the electric heat pump through the anti-corrosion and high-efficiency water-water plate heat exchanger and exchanges heat indirectly with the high-temperature circulating water. The electric heat pump uses the electric energy of the power plant as the driving power.
