Flue gas liquid dust slag spinning condensation heat exchange device and method

The invention relates to a smoke liquid dust slag spinning condensation heat exchange device. The smoke liquid dust slag spinning condensation heat exchange device comprises a smoke inlet flue and a smoke outlet flue, wherein the smoke inlet flue is connected with a furnace smoke outlet and forms an inclined angle; the smoke outlet flue is connected with the smoke inlet flue and is horizontally arranged; a heat exchanger is arranged on the flue gas outlet flue, and the flue gas heat exchanger is characterized in that a flow guide device is arranged in the flue gas inlet flue, and the flow guide device is composed of a plurality of flow guide plates; one end of each guide plate is fixed on the wall of the flue, and the other end of each guide plate is suspended in the flue. Meanwhile, the invention further discloses a smoke liquid dust slag spinning condensation heat exchange method. The industrial flue gas waste heat utilization efficiency can be improved, and the flue maintenance cost is reduced. 本发明涉及一种烟气液态
