In the present embodiment, high temperature is taken cloud of dust gas and is entered described flue gas waste heat recovery chamber 4 from described the first gas approach 6, in described flue gas waste heat recovery chamber 4, high temperature is taken cloud of dust gas and is carried out heat exchange and flowed downward simultaneously by described one-piece auger finned tube and the water body in the described one-piece auger finned tube of flowing through, when flue gas comes downwards to described the first gas flow through hole 25, cooling through described flue gas waste heat recovery apparatus 1 is processed, and the entrained most of heat of this flue gas is transferred in the water in described one-piece auger finned tube, then under the swabbing action of centrifugal high pressure fan, this flue gas enters in described water bath dust-removing desulfurizer by described the first gas flow through hole 25, because described dividing plate 11 is arranged between described the second gas approach and described the second exhanst gas outlet, be located between described the first gas flow through hole 25 and described the second gas flow through hole 26, edge and described sink cover 9 fixed seal connections on described dividing plate 11, and the left end of described dividing plate 11 and right two ends respectively with the cell wall fixed seal connection of described tank 10, after the interior injected water of described tank 11, at the water surface, exceed described dividing plate 11 lower along time, under the effect of fluid-tight, gas in described tank is divided into two directly parts of conducting by described dividing plate 11, in the case, the swabbing action of centrifugal high pressure fan makes to close on gas pressure in the described tank 10 of described the first gas flow through hole 25 far below the gas pressure that closes on described the second gas flow through hole 26 places and state in tank 10, and then flue gas is inhaled in the water in described tank 10, due to the liquid level in described tank 10 above 11 times edges of described dividing plate and and 11 times edges of described dividing plate between spacing meet water in described tank 10 and can not be passed described the second gas flow through hole 26 and be inhaled in described spraying and dedusting desulfurization chamber 14, therefore the water in described tank 10 can not be inhaled in described spraying and dedusting desulfurization chamber 14 through described the second gas flow through hole 26, flue gas forms bubble after being inhaled in water, the sulfide that water can be washed the dust contacting with it stay off in the interior while gas of described tank 10 is also dissolved in described tank 10, through the flue gas after water bath dust-removing desulfurization, by described the second gas flow through hole 26, enter in described spraying and dedusting desulfurization chamber 14, the water smoke spraying by described spray head 17 infiltrates dedusting, remaining dust particle thing and can be because infiltrated and to start to condense and form the bottom that water droplet drops to described spraying and dedusting desulfurization chamber 14 by water droplet containing emissions in flue gas, then through described the second gas flow through hole 26, flow in described tank 10, after flue gas after spraying and dedusting desulfurization rises, owing to carrying a large amount of steam, directly enter in atmosphere and can form white water smoke, not only can cause the waste of water, also can bring fear to surrounding resident, so added described gas and water separator 24 in the utility model, described gas and water separator 24 can be separated the steam carrying in the flue gas of a large amount of steam and reclaim from flue gas.The gas of processing through described gas and water separator 24 can directly drain in atmosphere through described the 3rd exhanst gas outlet 15.
In other embodiments, described flue gas waste heat recovery apparatus 1, when described water bath dust-removing desulfurizer 2 and described spraying and dedusting desulfurizer 3 are installed and used separately, in order to strengthen spraying and dedusting effect, can in described spraying and dedusting desulfurization chamber 14, close on one end fixed installation gas distribution orifice plate of described the 3rd gas approach, and described gas distribution orifice plate is provided with the gas flow through hole that runs through described gas distribution orifice plate upper face and lower face, in order to make described gas distribution orifice plate play better gas distribution effect, described gas flow through hole is evenly distributed on described gas distribution orifice plate, and the aperture of all described gas flow through holes is identical.
Above-described embodiment is only for the invention example is clearly described, and the not restriction to the invention specific embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.All any apparent variations of being extended out within spirit of the present utility model and principle or change are still among the protection domain in the invention claim.
