In the present embodiment, (steel, coal electricity industry, petrochemical industry that the flue gas induced duct 41 will be collected into using pipeline
Etc. industries) the wet plume of discharge, white fog (about 60-100 DEG C of temperature) etc. is sent into heat exchange box 2 and sticks up plate heat interchanger progress
Processing.The flue gas induced duct 41 is connected by flange with 2 bottom of heat exchange box, which primarily serves air inducing
Effect.
In the present embodiment, the alkali liquor storage tank 46 and spray equipment 3 are passed through mainly using the condensed water collected in the present invention
Part water is connected in alkali liquor storage tank 46 after filtration treatment, and alkali NaOH is added to adjust controlled concentration (NaOH/10%-20%)；Through lye
Booster pump 45 is promoted, and is introduced into the heat exchange of flue gas air inducing pipeline 41, temperature and flue-gas temperature are after, in a manner of spray, in mist
Change area and flue gas mixing.
The alkali liquor storage tank 46 is arranged below the flue gas induced duct 41, is promoted by lye booster pump 45, first by lye
It squeezes into the flue gas induced duct 41 and exchanges heat, handled by sticking up plate heat interchanger, materialization mixed zone is entered after heating, lead to
It crosses atomizing spray pipeline and spray head and is uniformly sprayed onto atomization mixed zone.
46 main function of alkali liquor storage tank be to provide in akaline liquid and flue gas in fine dust and particulate
Acidic materials, such as sulphur, sulfur dioxide etc. solve flue gas acid attribute question, play high purification purpose.So that being returned from flue gas
The water journey of receipts is neutral, and discharge gas journey is neutral.
The supersonic atomizing humidifier 47, will using the fume afterheat (between about 60-100 DEG C) in flue gas air inducing pipeline
After about 30-50 DEG C 5-15 DEG C of reheating of the condensed water condensed out in the present invention (energy saving, reduction waste), collect to ultrasonic wave
In humidifier water tank 44, humidified device water supply pump 43 is sent into supersonic atomizing humidifier 47 and is sprayed, and reaches the wet misty rain of purification, white
The purpose of dust and elimination pernicious gas in color misty rain, carries out secondary deep processing to 41 flue gas of induced duct.
The supersonic atomizing humidifier 47 is connected by flue gas induced duct 41, passes through ultrasonic transducer higher-order of oscillation work
It is uniformly discharged into flue gas with the water mist of generation, is uniformly mixed in range of atomization and flue gas, lye mist, increased humidity of flue gas, make
It obtains hydrone in flue gas and is in hypersaturated state.
The supersonic atomizing humidifier 47 effect is the alkali droplet dense fine full of free state in entire range of atomization, institute
There is a nitrogen oxides in flue gas, sulfide, various soot dust granule objects, aerosol, various grain of salt crystals substances pass through Shi Wuke
Avoid want and drop contact, be mixed effect first, and then acid-base neutralization reaction occurs, since humidity of flue gas increases,
It agglomerates, adsorbs, purifying smoke impurity in hypersaturated state, and then under molecular force effect.Atomization state flue gas is ultimately formed to exist
It being easier to condense into droplet and water droplet when passing through condensation module, the water and impurity to flue gas play a part of to agglomerate and promote cohesion,
Be conducive to the elimination of flue gas water mist.Eliminate white haze.
The water that the condensation water collection storage box 48 is condensed by collecting the present invention, a part is for cleaning heat exchange box
Namely the flue gas in induced duct 41 is cleaned three times, another part can be back to the secondary reuse of desulfurizing tower and original device
Reuse.
The condensation water collection storage box is mounted on the flue gas induced duct 41 in the following, being directly located at concrete foundation ground
On, by flanged joint, Cheng Santong form is connected with range of atomization 3 immediately above for water inlet and air inducing pipeline.Condensed water is being atomized
Area 3 converge after along answer air hose to by gravity flowing into condensation water collection storage box 48.
Embodiment 2
Referring to Fig. 2, Fig. 3, the difference is that, steel is provided at the top of heat exchange box 2 of the present invention with above-described embodiment
Plate 212, the steel plate 212 are connect by flange 213 with heat exchange box 2.
The bottom end of the heat exchange box top half 21 is connect by flange 216 with heat exchange box lower half portion 22.The heat exchange box
21 side of top half includes side steel plate 214.
Heat exchange box lower half portion 22 include it is round stick up plate heat interchanger 221, this is round, and to stick up plate heat interchanger 221 include outer
Frame 226 is provided with connector 227 and at least two heat exchanger tubes 229 in the outer framework 226, is additionally provided with fin stainless steel
Pipe 224；The connector 227 is connect with outer framework 226 and heat exchanger tube 229 connects, and is connected between the heat exchanger tube 229 by fin 228
It connects, the fin 228 is also connected with outer framework 226；It include cleaning spiral 225 in the heat exchanger tube 229.
22 side of heat exchange box lower half portion includes side steel plate 222, which passes through method
Orchid 223 connect with flue gas induced duct 41.
The heat exchange box top half 21 includes that at least two rows of squares stick up plate heat interchanger 211, and every row's heat exchanger 211 includes
At least two stick up plate heat interchanger 211；The square, which sticks up plate heat interchanger 211, arranges angled, first row and second row
It is contrary.
The square sticks up 211 narrow side of plate heat interchanger and welds elongated fin, and 100-300 millimeters of broadside spacing or so welding are stuck up
Piece, adjacent 2 square tube fins link together；The square sticks up 211 arrival end of plate heat interchanger and outlet end using stainless steel
Plate is laser-cut into the identical mouth of square tube size together with square tubes soldering.
