Spraying zone 101 is likewise supplied with higher dust removing effects, is that the multilayer of arranged in series is inversely spraying inside reaction tube 10 Reaction tube nozzle 1, the shaped Venturi dedusting function of the existing similar high flow rate of this structure, while flue gas resistance is controlled again can Receive range, while further improving efficiency of dust collection by way of spraying layer of connecting.It is this to have used high flow rate high-intensitive All standing mode, enhances mass transport process significantly, can significantly increase mass tranfer coefficient, can reach complete strong washing physically Effect, especially has good removal effect to 20 microns with junior's dust, and this mode can reach finely removing for 80-90% Dirt efficiency.
Desulfurization and denitration reaction principle when mixed liquor bulk composition is ammonium persulfate is as follows:
Specifically, in spraying zone 101, the SO in the flue gas of reaction is participated in2Concentration is lower, generally below 200mg/ Nm3, since ammonium persulfate aqueous solution is also with higher physical or chemically desulfuration efficiency, generally higher than 50%, mainly By water to gas SO2Solution absorption ability, specific reaction is as follows:
Desulphurization reaction:
SO2+H2O→SO2·H2O (1)
SO2·H2O→HSO3 -+H+ (2)
HSO3 -→H++SO3 2- (3)
(NH4)2S2O8→2NH4 ++S2O8 2- (4)
SO3 2-+2NH4 +→(NH4)2SO3 (5)
2(NH4)2SO3+O2→2(NH4)2SO4 (6)
Denitration reaction:
2NO+3(NH4)2S2O8+4H2O→2HNO3+3(NH4)2SO4+3H2SO4 (7)
2NO+O2+H2O→HNO2+HNO3 (8)
2NO2+H2O→2HNO3+NO (9)
Ammonium persulfate reacts principle in NOx and mixed liquor in flue gas:
NOx in flue gas leans on DIFFUSION IN TURBULENCE from gas phase main body to gas mould surface, and is reached by molecule diffusion by gas mould It, by means of the concentration gradient of gas-liquid two-phase, is spread by molecule to two-phase interface when the NOx in gas phase is contacted with mixed liquor Process, NOx form HNO from liquid film surface to liquid phase main body from two-phase interface, from liquid film by DIFFUSION IN TURBULENCE in the liquid phase3With HNO2, it is ionized into H respectively+、NO3 -And NO2 -, while the ammonium persulfate that NO is mixed in liquid is oxidized to readily soluble NO2, improve Gas phase and liquid phase motive force of the NOx when gas phase enters liquid phase.
After ammonium persulfate aqueous solution denitration, the gaseous state NOx of about 30%-50% is only converted into liquid, it is also necessary to By adding Ca (OH)2It is fed again into boiler SNCR denitration system after neutralization reaction and carries out denitration in the stove, by calcium nitrate and nitrous acid Calcium heat resolve generates NOx and carries out denitration reaction again, and comprehensive denitration efficiency is in 25%-40%, and denitration can in this way The nitrate generated to avoid wet oxidation denitration can not be handled, and outlet can lead to the problem of secondary pollution, also avoid simultaneously Nitric acid and nitrous acid can be by SO in flue gas2The problem of inferior sulfate radical of generation is reduced into NO.
Due to Ca (OH)2From a wealth of sources, operating cost is low and safety is higher, is only needing desulfurization and dedusting function In the case of use Ca (OH)2Solution, and can achieve 90% or more desulfuration efficiency, desulfurization can be reached to minimum discharge standard. Desulfurization specifically reacts as follows:
SO2+Ca(OH)2→CaSO3(precipitating)+H2O (10)
CaSO3+SO2+H2O=Ca (HSO3)2 (11)
Certainly, also there are other reactions, such as: demercuration.
Hg in flue gas2+The ratio for accounting for gaseous mercury total amount is 40%~50%, Hg050%~60%. is accounted for existing wet process Desulfurizer carries out the removal of mercury, can absorb in flue gas 80%~90% Hg2+, but to Hg0Remove unobvious, wet desulphurization mercury removes Mercury efficiency depends on Hg0Absorption efficiency, mercury Hg0Solubility in water is very low, and infiltration rate is by liquid phase draught control, usually Soluble form such as Hg is translated into mass transfer boundary layer2+, therefore pass through the effect of strong oxidizer ammonium persulfate, it can To reach about 60% demercuration efficiency, specific reaction is as follows:
S2O8 2-+Hg0→2SO4 2-+Hg2+ (12)
Flue gas after preliminary purification with a large amount of droplets enters dedusting area 102, by the effect of adsorbent 3 by droplet It is removed with dust particles, the flue gas b after final purification enters downstream temperature rise heat exchanger 600 (if any) and chimney is discharged into atmosphere.
Flue gas enters dedusting area 102 after passing through spraying zone 101.The main function of dedusting area 102 be by a large amount of droplets and The dust particles removal that droplet carries.Dedusting area 102 is mainly made of adsorbent 3 and flushing pipe network.
Adsorbent 3 is due to having the function of that intensive netted multilayered structure has removal droplet and dust particles well. Cardinal principle: gentle by inertial collision, retention, Blang's diffusion, gravitational settling when flue gas containing droplet is by inside device When body absorption, mist droplet can be adsorbed on inside device on paved set body structure surface.Surface tension of liquid polymerization and hair Thin phenomenon makes mist droplet agglomeration become bulky grain droplet, and droplet declines because of gravity, reaches defogging effect.Adsorbent 3 can generally remove the 99.5% of 99% and the 10 μm of droplets that account for whole 5 μm of droplets, and the demisting of 1~5 μm of droplet is imitated Rate is also very high, up to 60% or more.
Since existing desulfurizer mist eliminator not can be removed 15 μm of droplets below, this part droplet carries a large amount of powder Dirt and soluble-salt, considerably increase dust emission concentration, because of a large amount of dust that droplet carries in general desulfurizing tower exiting flue gas About 5-15mg/Nm is reached with the increased dust concentration of soluble-salt3, removal of the adsorbent 3 of the present apparatus to this part droplet Rate reaches 99%, provides basic guarantee to reach dust minimum discharge.
Contain a large amount of droplet in wet flue gas after desulfurization, droplet concentration is in 25-75mg/Nm3Or so, contain in droplet The sundries such as sticking gypsum slurries, dust, it is easy to which the felt jam on adsorbent, the present invention are being sprayed using mixed liquor The a large amount of solution droplet that area constantly generates mixes the droplet containing sundries such as sticking gypsum slurries, dust After dilution, while the time for making mist droplet agglomeration become bulky grain droplet accelerates, the speed that droplet declines by gravity Accelerate, it is entirely avoided the felt jam problem of adsorbent.Based on this reason, positioned at flat-top four sides centrum intermediate space It rinses main pipeline 22, rinse lateral 23 and adsorbent flooding nozzle 2, the only unlatching when circulatory pool requires supplementation with liquid level, punching It is secondary for washing the effect of flat-top four sides centrum.
Flue gas flow rate is excessively high in desulfurization duct, and in 10-15m/s by design specification, flue gas passes through with intensive net The multilayered structure of shape can generate very big flue gas resistance, at the same too fast flue gas flow rate also can secondary droplets droplet, make to adsorb The removal droplet of body and the efficiency of dust decline to a great extent.The present invention is effectively increased by unique flat-top four sides vertebral body structure Flue gas circulation area, reduces flow velocity of the flue gas by adsorbent, controls the flue gas resistance of adsorbent in 200Pa- 500Pa, meanwhile, avoid the secondary droplets droplet of adsorbent.
The a large amount of solution droplet constantly generated using mixed liquor in spraying zone based on the present invention is sticking to containing The droplets of the sundries such as gypsum slurries, dust carries out the felt jam problem that adsorbent is just completely avoided after mixed diluting, can be with Water is supplemented as circulatory pool using desulfurization wastewater or treated desulfurization wastewater, it is desirable that desulfurization wastewater solid content is controlled in desulfurization It will be de- after neutralization for next step while 5% solid content that system operates normally desulfurization wastewater can be used in this way Sulphur waste water is sent into boiler and provides condition.
The decline of 6 liquid level of circulatory pool exports a branch line from mixed liquor circulating pump 4, and the branch line is by over cure Mixed liquor after sour ammonium denitration reaction is sent into neutralizing tank or by dust-laden aqueous solution or Ca (OH)2Mixed solution after desulphurization reaction It is sent in the urea storage tank of the SNCR denitration system of boiler, after mixed liquor is mixed with urea liquid, is increased newly in urea liquid (NH4)2SO4、CaSO4、CaN2O6、 Ca(NO2)2、Ca(OH)2And dust and gypsum, while the relatively low alkalinity of pH value on a small quantity., and (NH4)2SO4Or Ca (OH)2Addition can greatly improve the efficiency of SNCR denitration in the stove, while CaN2O6、 Ca(NO2)2In height Temperature is lower to regenerate NOx, this part increases NOx newly and can remove by the way that urea is most of again in furnace, other a small amount of dust with Gypsum can be collected by downstream deduster and be removed, so new adverse effect can't be caused to boiler.In in circulatory pool 6 Mixed liquor with after is added in the urea liquid of original existing SNCR system, it is ensured that mixed liquor is in longtime running mistake The sundries constantly accumulated in journey is such as: the concentration of the ion of gypsum, dust and various chemical reaction products remains In reduced levels, it not will cause system equipment and corrosive pipeline blocking, adsorbent blocking, realized simultaneously also by this mode Desulfurization wastewater evaporates in boiler and achievees the purpose that the real zero-emission of desulfurization wastewater, and is sent into the mixing of SNCR denitration in the stove Flow quantity is greater than about 50 times of wastewater flow that desulphurization system need to discharge, and the chloride ion that can be diluted significantly in desulfurization wastewater is dense Degree, can not have to consider desulfurization waste water quality to the etching problem of boiler body and follow-up equipment, boiler in auxiliary device 200 SNCR denitration system 202 can using the SNCR spray gun model and its boiler position of opening of former boiler matching, but must with mix Liquid pump pressure and flow parameter and its mixed liquor ingredient match, and otherwise need to change or change SNCR spray gun in boiler aperture position It sets.The equipment that existing most of producer can be used in SNCR spray gun model, without limitation.It is de- that mixed liquor accesses original boiler SNCR The pipeline 316L of the urea storage tank of nitre system.The pipeline and equipment of contact ammonium persulfate mixed liquor in whole system It is all made of lined ceramics or liner tetrafluoride material, it is basic that the selection of material is that ordinary skill designing technique personnel should have Feature can't be the right for changing patent.Equally, as long as the design of internal system other equipment, tube pass and specification To meet the right that any design change that present apparatus operation is carried out all can't be change patent.
