The invention belongs to the technical field of industrial flue gas treatment, and particularly relates to a partition plate type industrial flue gas waste heat recycling device. The partition plate type industrial flue gas waste heat recycling device comprises a waste heat recycling shell, a flue gas inlet shell, a flue gas outlet shell, a steam outlet shell, a steam outlet pipe, a flue gas channel and a water spraying component. According to the partition plate type industrial flue gas waste heat recycling device, industrial flue gas is introduced into the sheet-shaped flue gas channel, so that the heat exchange efficiency among the industrial flue gas, the flue gas channel and water is improved, double-sided heating can be realized, the contacted water can be quickly converted into water vapor, and the utilization efficiency of waste heat of the industrial flue gas is improved; and the inclined flue gas channel is arranged, so that water falling on the flue gas channel slides downwards along the flue gas channel under the action of the gravity of the water, the water continuously makes contact with the surface of the flue gas channel with the higher temperature in the downward sliding process, then the water on the flue gas channel is rapidly evaporated, and the utilization efficiency of the industrial flue gas waste heat in the flue gas channel is further improved.
Description
technical field [0001] The invention belongs to the technical field of industrial flue gas treatment, in particular to a clapboard type industrial flue gas waste heat recovery device. Background technique [0002] Over large industrial cities, because a large amount of industrial smoke is discharged into the air, the residual heat in the industrial smoke will make the air temperature near the city's surface higher than that of the surrounding suburbs. This phenomenon is called "heat island effect" in meteorology. . Therefore, the heat in industrial flue gas must be treated before it can be discharged safely; the best treatment method is to be able to recover and reuse the waste heat in industrial flue gas; among them, the heat pipe waste heat recovery device is coal, oil, Special equipment for gas boilers, installed at the boiler smoke port, recovering waste heat from flue gas to heat domestic water or boiler water supply. Its structure: the lower part is the flue, the upp...
