Description
The present invention relates to a kind of electronic beam method flue gas desulfurization technique.
The electronic beam method flue gas desulfurization technique is a kind of physics and the new and high technology that chemistry combines, and can remove sulfur dioxide and nitrogen oxide from gas fume after burning simultaneously.This technology utilizes the electron beam of electron accelerator generation to the N in the flue gas
2, O
2And H
2O shines, and produces free radical and atom, and they are oxidized to separately acid substance to sulfur in smoke and nitrogen oxide, and is neutralized into ammonium sulfate and ammonium nitrate with the ammonia that adds, and separates from flue gas then, to reach the purpose of clean flue gas.Existing electronic beam method flue gas desulfurization technique is divided into dry method, two kinds of technologies of semidry method according to the operation conditions of capital equipment in the flow process both at home and abroad.
Japan Ebara company has proposed electron beam dry flue gas desulphurization technology in 1970, it mainly adopts dry type device processes flue gas.To remove the flue gas of flying dust after boiler induced-draft fan is drawn, the spraying and sprinkling evaporation cooling tower of flowing through is evaporated water for cooling, humidification, dust removal therein, flows to horizontal radiation chamber then, the electron beam that utilizes electron accelerator to produce shines ionization N wherein to flue gas
2, O
2And H
2The O molecule forming free radical and atom, and then is oxidized to sulfuric acid and nitric acid to sulfur dioxide and nitrogen oxide, last again with horizontal radiation chamber in the ammonia that injects synthesize ammonium sulfate and ammonium nitrate aerosol particles.In horizontal radiation chamber, will go up water and ammonia sprays into simultaneously,, make the exit gas temperature of horizontal radiation chamber, still remain on about 60 ℃ of import department in order to the heat that the evaporation latent heat absorption reaction of water produces.After these ammonium salt aerosol particles leave horizontal radiation chamber, from flue gas, separated, after the comminutor granulation, generate byproduct ammonium salt chemical fertilizer then by a dry electrostatic cleaner.Purified gas after the desulfurization is sent into smoke stack emission by the desulfurization booster fan after the regenerator heating.
Electron beam dry flue gas desulphurization technology is moved, builds, is designed maybe and can grind in the thermal power plant on the ground such as Chengdu, Tianjin, Hangzhou, Guizhou of Japan Nagoya and China.The advantage that this technology is outstanding is that its flow process is extremely simple, includes only four process sections such as cooling tower, horizontal radiation chamber, dry electrostatic cleaner and comminutor, and initial cost is less, for commercialization lays the foundation.But this technology is in service, and under the flue gas control parameter of low temperature, high humidity, required smoke absorption irradiation dose can reduce on the one hand; The average diameter of ammonium salt aerosol particles is at 0.5-2.0 μ m on the other hand, and specific area is big, belongs to hydrophilic dust in addition, makes in its dry type separation equipment under super-humid conditions, shows extremely strong adhesiveness; The also improvement of the desired flue gas temperature of established technology, wet control parameter is subjected to the restriction of dry type separation equipment service condition, thereby causes following problem:
1, required smoke absorption electron beam irradiation dosage is bigger than normal;
2, because the spray distance of last water in horizontal radiation chamber is shorter, and the water droplet that has little time to evaporate can absorb quite a few electron beam, thereby the block electrons bundle is to the irradiation of flue gas:
3, the ammonium salt aerosol particles need be handled through the bigger comminutor of power consumption, can sell as agrochemical;
4, horizontal radiation chamber need be provided with spray system and mechanical screeding device;
5, ammonium salt aerosol particles caking in the dry electrostatic cleaner, thus positive plate rapping apparatus and mechanical screeding device need be established;
6, ease ammonia concentration is higher;
7, the process system power consumption exceeds 3% of the clean generating of thermal power plant.
For addressing the above problem, U.S. VAC company has released the electron beam semi-dry method flue gas desulfurization technique.It adopts wet cottrell to separate, clean out ammonium salt solution, sprays into evaporation the drier, dry, granulation from the top by rotarytype injector, forms the ammonium salt particle of diameter about 100 μ m; Wherein account in 55% coarse granule ammonium salt directly is collected in the spray dryer bottom under the gravity effect the hopper; Meanwhile flue gas is evaporated water humidification and cooling, flows to then in the dry electrostatic cleaner, collects all the other fine grained ammonium salts of 45% by it.Flue gas flows to before the horizontal radiation chamber, also needs to go up water and compressed-air actuated second-rate multiinjector cooling tower through one, to flue gas cool-down, humidification, is injected into theoretical chemistry dosage than the ammonia that is 1 in the flue outside its outlet with further then.Before liquefied ammonia at first was stored in the container under certain pressure and flue gas mixes, liquefied ammonia needed through gasifying in an evaporimeter after the throttling.In horizontal radiation chamber, utilize the N in the electron beam irradiation flue gas
2, O
2And H
2The O molecule, to produce free radical and atom, they are oxidized to separately acid substance fast with sulfur dioxide and nitrogen oxide, last these oxidizing acids and ammonia carry out neutralization reaction in horizontal radiation chamber and wet cottrell, form the ammonium salt aerosol particles of diameter at 0.5-2.0 μ m, and charged by wet cottrell, separate, be washed to ammonium salt solution, send in the spray dryer spraying, dry, granulation at last.The purified gas that comes out from wet cottrell also needed by a demister demist before entering air-introduced machine, and was heated coil pipe and is heated to more than the purified gas acid dew point, to reduce the corrosion in air-introduced machine and follow-up purified gas air channel.In addition, at horizontal radiation chamber and to the flue between the wet cottrell nozzle is set, be used for regularly under low temperature, the super-humid conditions on wall easy the to be molten ammonium salt adhesion layer of accumulation be washed to ammonium salt solution, discharge from lodgment, and deliver in the spray dryer spray, dry, granulation.
The electron beam semidry process that adopts wet cottrell recovery ammonium salt aerosol particles is with respect to the electron beam dry process, though from the principle, part has solved the contradiction of flue gas temperature, wet control parameter and wet separation equipment service condition, and its cost is:
1, technological process is made up of six process sections such as spray dryer, dry electrostatic cleaner, cooling tower, horizontal radiation chamber, wet cottrell and demisters, almost prolong half than the electron beam dry process, thereby increased substantially the process system cost;
2, system's control also increases to six closed loops, and is quite complicated;
3, on the vertical anode plate of wet cottrell for keeping the thick freely falling body flushing moisture film of 3mm, the mass flow of required circulated sprinkling solution is 4 times of smoke treatment mass flow, makes that the power consumption of circulation solution pump is almost identical with the system air-introduced machine;
4, a large amount of horizontal equipment that adopt such as dry electrostatic cleaner, cooling tower, horizontal radiation chamber, wet cottrell and demister, under the high humidity service condition, still can there be the wall agglomeration problems, and be difficult to use that gravity washes away and deslagging, thereby need be aided with all regularly that spray washes away system, and be required to be wherein the bottom deslagging of every horizontal equipment and look for the slope and mechanical rubbing board device is set;
Even 5, owing to the press spray drier of granulation average diameter maximum, its average granulation particle diameter still is lower than the lower limit of ammonium salt nitrogenous fertilizer standard particle diameter.
The advantage that the objective of the invention is integrated electronics bundle dry process and electron beam semidry process, overcome the weak point of its existence simultaneously, cost with minimum thoroughly solves the contradiction that the flue gas that exists in the electron beam dry process is controlled parameter and dry type separation equipment service condition, a kind of flow process is simple, control is easy, equipment is few, power consumption is low, occupation of land is little thereby provide, and the big electronic beam method flue gas desulfurization technique of byproduct particle diameter.
