Heat recovery heating device for desulfurized slurry

The utility model discloses a heat recovery heating device for desulfurized slurry. The heat recovery heating device for the desulfurized slurry comprises a spraying tower body and a heating water pipe. A spraying water-returning pipe connected with a spraying device on the top of the spraying tower body is arranged on the bottom of the spraying tower body and provided with a split type heat pipe, the split type heat pipe is connected with a heat pump arranged on the heating water pipe, and heat pump heat exchangers are arranged between the heat pump and the split type heat pipe and between the heat pump and the heating water pipe respectively. According to the heat recovery heating device, the spraying slurry of the spraying tower body is recovered, the heat in the recovered spraying slurry is exchanged and recycled, and therefore the heat recovery and utilization rate of the wet desulphurization process is effectively increased, the energy is saved, and the environment is protected.
