x) there is reduction reaction.The outer denitration of stove allows flue gas enter SCR reaction tower, under the effect of catalyst, make NH
3with NO
xreaction.This equipment portfolio investment is large, takes up an area large, and power consumption, water consumption is large, and operating cost is high.
Utility model content
For above-mentioned technical problem, the utility model provides gas cleaning plant, and dedusting, desulphurization and denitration are included in same system and processed, and reduces energy consumption and investment.Concrete technical scheme is:
Dust-removal and desulfurizing denitrification integrated device, comprise two towers, be respectively air inlet tower and tower of giving vent to anger, described air inlet tower is communicated with circulatory pool respectively with the bottom of tower of giving vent to anger, arc and aerator is also comprised in described circulatory pool, described arc is arranged on circulatory pool top and at air inlet tower with give vent to anger between tower bottom, and air inlet tower, give vent to anger tower and circulatory pool, bottom circulatory pool, are formed a U-shaped structure by arc crowning; Described air inlet top of tower has air inlet, is oxidation tank below air inlet, is range of atomization below oxidation tank; Described top of tower of giving vent to anger has gas outlet, has demister below gas outlet, is provided with disc type water-locator below demister, is gas-liquid net below disc type water-locator.
Described arc is provided with spray equipment.
Flue gas enters air inlet tower from air inlet, and in oxidation tank, NO is oxidized to NO
2, SO
2be oxidized to SO
3, then range of atomization changes into ammonium nitrate and sulphur ammonia.Continue to move downward, enter circulatory pool, product and the soot dust granule of reaction in air inlet tower fall in circulatory pool.Flue gas is when arc extrudes simultaneously, and the spray equipment of aerator and arc washs flue gas.Last flue gas is through entering tower of giving vent to anger, and fully contact washing reaction at gas-liquid net with liquid, after final dewatering, the flue gas be cleaned is discharged through gas outlet.
The dust-removal and desulfurizing denitrification integrated device that the utility model provides, realizes dedusting, desulphurization and denitration three cover system function set of system, solves the problem that floor space is large, system investments is large, operating cost is high.And traditional unit equipment three overlaps drag overall at least needs 4000Pa, and this device is in identical processing capability scale, only needs 1000Pa, reaches good energy-saving effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Accompanying drawings detailed description of the invention of the present utility model, as shown in Figure 1, dust-removal and desulfurizing denitrification integrated device, comprise two towers, be respectively air inlet tower 100 and tower 200 of giving vent to anger, described air inlet tower 100 is communicated with circulatory pool 7 respectively with the bottom of tower 200 of giving vent to anger, arc 4 and aerator 6 is also comprised in described circulatory pool 7, described arc 4 be arranged on circulatory pool 7 top and bottom air inlet tower 100 and tower 200 of giving vent to anger between, air inlet tower 100, give vent to anger tower 200 and circulatory pool 7, bottom circulatory pool 7, are formed a U-shaped structure by arc 4 crowning;
Air inlet 1 is arranged at described air inlet tower 100 top, is oxidation tank 2 below air inlet 1, is range of atomization 3 below oxidation tank 2;
Gas outlet 11 is arranged at described tower 200 top of giving vent to anger, and having demister 10 below gas outlet 11, be provided with disc type water-locator 9 below demister 10, is gas-liquid net 8 below disc type water-locator 9.
Described arc 4 is provided with spray equipment 5.
The course of work is: flue gas is incorporated into air inlet 1 through air-introduced machine and enters air inlet tower 100, is introduced into oxidation tank 2, and the oxidant in oxidation tank 2 is generally hydrogen peroxide, and NO is oxidized to NO
2, SO
2be oxidized to SO
3.Oxidation tank 2 lower end is range of atomization 3, and range of atomization 3 atomized liquid is ammoniacal liquor, NO
2+ NH
3→ NHNO
3, NO
2change into ammonium nitrate, SO
2+ H
2o+NH
3→ NHSO
4, SO
2change into sulphur ammonia.
When mixed flue gas continues to move downward, enter circulatory pool 7, by the extruding of friction and the arc 4 pairs of flue gases with the liquid level in circulatory pool 7, add the mixing of flue gas.Now flue gas break-in, due to the effect of gravity and centrifugal force, makes the product of reaction in air inlet tower 100 and soot dust granule fall in circulatory pool 7.Flue gas is through arc 4 lower end simultaneously, and aerator 6 and spray equipment 5 acting in conjunction of arc 4, make flue gas through washing.Last flue gas is through entering tower 200 of giving vent to anger, uniform liquid in circulatory pool 7 is sprayed onto on gas-liquid net 8 by the disc type water-locator 9 above gas-liquid net 8, flue gas fully contacts washing reaction with liquid on gas-liquid net 8, dewater through demister 10, the flue gas be finally cleaned is discharged through gas outlet 11 again.
Aerator 6 adds the contact of flue gas and circulation fluid, adds the efficiency of dust-removal and desulfurizing.
The space that between the liquid level of arc 4 and circulatory pool 7, gas circulates diminishes, and is equivalent to Venturi tube to flue gas compressor, increases flue gas and the contact of atomization circulation fluid, increases effect.
Arc 4 bottom and 45 ° of angles respectively arrange a spray equipment 5, flue gas is through arc 4 lower end, accept the washing of arc 4 Shang tri-road spray equipment 5, and the spray that after aeration, the water surface is formed adds the effect of dedusting and desulfurization jointly to washing simultaneously.
Flue gas is when through gas-liquid net 8, the liquid of alkalescence is sprayed onto downwards on gas-liquid net 8 by gas-liquid net 8 top disc type water-locator 9 equably, flue gas is moved upward by gas-liquid net 8 lower end, and this process flue gas and alkali lye is abundant haptoreaction again, is again one-time dedusting, desulphurization and denitration process.
Steel mill's heating furnace of certain Iron And Steel Co., Ltd is tested, former exhaust gas dust content 3087mg/m
