The hot water heat exchanger uses the flue gas generated in boiler to carry out heat exchange as heat source and cold water.
The hot water heat exchanger is coil heat exchanger.
The invention has the benefit that
The present invention enters warm air curtain after water to be heated to kiln hood, kiln tail boiler exhaust gas waste heat by coil heat exchanger, empty
Gas is entered grate-cooler after the water heating in warm air curtain, and air after heating introduces the recycling of grate-cooler waste heat, can be improved kiln hood,
Kiln tail boiler inlet smoke temperature increases the generated energy of kiln head and tail boiler, energy saving；Kiln hood, the recycling of kiln tail boiler exhaust gas waste heat,
Reduce influence of the greenhouse gases to environment.
Air after heating is introduced grate-cooler by the present invention, and waste heat recovery efficiency is high, without supplementing fuel in power generation process,
Any pollution is not generated, it is a kind of environmentally friendly, energy-saving and emission-reduction which, which meets the Green power generation technology of national industrial policies,
Meet the circular economy technology of sustainable development requirement, economic benefit highly significant.
The present invention applies in the smoke evacuation for producing 5000 tons of cement clinker production line kiln hoods, kiln tail boiler daily at one, introduces and combs
Cold can solve 11.4% clinker production from electricity consumption daily using 2.4 ten thousand degree of cogeneration, product comprehensive energy consumption can under
Drop about 4%, it is annual to save about 2900 tons of standard coal, about 6900 tons of reducing emission of carbon dioxide.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of snakelike tube bank waste-heat recovery device of the present invention.
Appended drawing reference in figure, 1 is chimney, and 2 be flue, and 3 be cold water pipe, and 4 be hot water heat exchanger, and 5 be hot-water line, and 6 are
Warm air curtain, 7 be grate-cooler.
Specific embodiment
Below in conjunction with attached drawing, the present invention is described in further detail: the present embodiment is being with technical solution of the present invention
Under the premise of implemented, give detailed embodiment, but protection scope of the present invention is not limited to following embodiments.
As shown in Figure 1, a kind of snakelike tube bank waste-heat recovery device involved in the present embodiment, comprising: flue 2, cold water pipe
3, hot water heat exchanger 4, hot-water line 5, warm air curtain 6 and grate-cooler 7；
Wherein, the both ends of flue 2 are connected with chimney 1 and waste heat boiler respectively, and hot water heat exchanger 4 is provided in flue 2,
The lower end of hot water heat exchanger 4 is connected with cold water pipe 3, and the upper end of hot water heat exchanger 4 is connected by hot-water line 5 with warm air curtain 6,
