Flue gas moisture recovery, flue gas purification and waste heat utilization combined system device

The utility model discloses a flue gas moisture recovery, flue gas purification and waste heat utilization combined system device. The device comprises a condensation heat exchange pipe, a sound wavecoagulator, a fine fog drop separator, a condensation separator flue, a condensate water storage tank, a compressor, a heat pump and a condensing agent buffer tank. The device disclosed by the utilitymodel is arranged in a desulfurized flue, and flue gas is cooled by utilizing a low-boiling-point condensing agent, so that moisture in saturated flue gas at a desulfurization outlet is condensed andseparated, and efficient recovery of the moisture in the flue gas is realized; fine fog drops and fine particle pollutants are condensed into large particles by utilizing an acoustic wave condensation technology, and gas-liquid further efficient separation is carried out by utilizing a fine fog drop separator, so that the fine particle pollutants in the flue gas are efficiently dehydrated and synchronously removed; condens
