Abstract
The invention relates to the technical field of energy saving and emission reduction, in particular to a waste heat integration recycling device. The waste heat integration recycling device comprisesan annealing furnace, a smoke pipeline extending towards the outer side of the annealing furnace is communicated with the annealing furnace, and a gas storage tank used for collecting steam is communicated with the tail end of the smoke pipeline; the waste heat integration recycling device further comprises an evaporation device, the evaporation device comprises a pair of clapboards and a pair ofbaffles, water seepage plates are connected to the clapboards, one ends of the water seepage plates penetrate through the clapboards, water seepage pipes are further connected to the ends, and the water seepage plates on the side walls of the two clapboards are mutually staggered; a smoke channel is formed between every two adjacent staggered water seepage plates, a water storage box is connectedto the water seepage pipes, a water outlet device is further arranged on the water storage box, and several water seepage holes are uniformly and densely distributed in the surfaces of the water seepage plates. High-temperature smoke is in contact with a water film so that the water film can be vaporized into water vapor which can follow the high-temperature smoke to flow, these gases can be regarded as steam power energy sources of other processes, and the technical problem in the prior art that the high-temperature smoke cannot be utilized, and energy sources are wasted is solved.
Description
technical field [0001] The invention relates to the technical field of energy saving and emission reduction, in particular to a waste heat integrated recovery device. Background technique [0002] At present, the existing steel production needs to undergo heating, heat preservation, air cooling, slow cooling, etc. in the annealing furnace. The temperature of the steel after the annealing process usually reaches 550°C. After being output from the annealing furnace, it needs to be cooled. It has no effect on the annealed structure of the steel, but the steel still has a large heat capacity, and a large amount of heat energy will be wasted with the cooling of the material. Not only that, the high-temperature flue gas in the flue in the annealing furnace also contains a large amount of heat , with the increasingly tense energy supply, the application of new energy-saving technologies has been paid more and more attention. At present, the existing exhaust duct only lowers the te...
