Abstract
The invention discloses a simple ammonia-method desulfurization tower with an externally-arranged reactor. The desulfurization tower comprises a tower body, a reactor assembly, a water rinsing assembly and a demister, wherein the reactor assembly is communicated with the side face of the lower part of the tower body, the reactor assembly is integrally located outside the tower body, the water rinsing assembly and the demister are located at the internal upper part of the tower body, and a fume outlet is formed in the top of the upper part of the tower body. The desulfurization tower has the advantages that fume reacts with ammonia water through the reactor assembly on the side face of the tower body and then enters the tower body, and the fume after reacting vertically rises, is subjected to secondary absorption and demisting and then is exhausted from the top of the tower, so that the ammonia content of outlet fume is decreased to be below 10 mg/m<3>, and aerosol is difficult to form; and the fume vertically rises and is exhausted, so that the demisting efficiency is increased, and the water content of the fume is reduced.
Description
Technical field
The present invention relates to a kind of flue gas desulfur device, particularly a kind of desulfurizing tower that utilizes simple and easy ammonia process to carry out flue gas desulfurization.
Background technology
The old-fashioned desulfurizing tower that utilizes simple and easy ammonia process to carry out flue gas desulfurization, its structure as shown in Figure 1, reactor assembly 1 is erect and is positioned at tower body 2 centres, demister 3 and flushing water assembly 4 are positioned at the afterbody outer peripheral areas of reactor assembly 1 in tower body 1.Flue gas adopts enterprising side to go out, and enters in the reactor assembly from tower body top import and reacts with ammoniacal liquor, then discharges from the outlet of tower body side after demist in tower body.This structure outlet flue gas is easily walked monolateral, and is undesirable except fog effect, do not solve simultaneously ammonia escape and flue gas and easily forms the aerosol problem.
Summary of the invention
Goal of the invention: for the problems referred to above, the purpose of this invention is to provide a kind of ammonia content after the flue gas desulfurization, effective desulfurizing tower of demist of reducing.
Technical scheme: the simple and easy ammonia process desulfuration tower of a kind of reactor externally positioned type, comprise tower body, reactor assembly, flushing water assembly, demister, described reactor assembly is communicated with described tower body lower side, it is outside that described reactor assembly all is positioned at described tower body, described flushing water assembly and described demister are positioned at described tower body internal upper part, and top, described tower body top is exhanst gas outlet.
Also comprise the double absorption device, described double absorption device is positioned at described flushing water assembly and described demister below.
Beneficial effect: compared with prior art, to be flue gas enter tower body to advantage of the present invention after the reactor assembly of tower body side and ammoniacal liquor reaction, reacted flue gas vertical lifting is discharged by cat head after double absorption and demist, makes the ammonia content of outlet flue gas be down to 10mg/m
3Below, being difficult for forming aerosol, the flue gas vertical lifting is discharged, and demist efficient improves, and reduces flue gas moisture.
Description of drawings
Fig. 1 is the simple and easy ammonia process desulfuration tower structural representation of prior art;
Fig. 2 is structural representation of the present invention;
Arrow is flue gas flow direction shown in the figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in Figure 2, the simple and easy ammonia process desulfuration tower of a kind of reactor externally positioned type comprises tower body 1, reactor assembly 2, flushing water assembly 3, demister 4, double absorption device 6.Reactor assembly 2 is communicated with tower body 1 lower side, and reactor assembly 2 all is positioned at tower body 1 outside.Flushing water assembly 3, demister 4, double absorption device 6 are at tower body 1 internal upper part, and double absorption device 6 is positioned at flushing water assembly 3, demister 4 belows.Flue gas is entered in the tower body 1 by reactor assembly 2, and exhanst gas outlet 5 is arranged at top, tower body 1 top.
The present invention is introduced flue gas by the reactor assembly of tower body side, flue gas in the reactor assembly with ammoniacal liquor reaction after, below vertical lifting in the tower body, after double absorption and demist, discharged by cat head, greatly lowered the ammonia content of outlet flue gas, be difficult for forming aerosol, the flue gas vertical lifting is discharged simultaneously, demist efficient is improved, reduced flue gas moisture.
Desulfurizing tower of the present invention because the reactor assembly all is positioned at outside the tower body, therefore has etch-proof advantage when having solved the prior art defective, take up an area larger problem but exist.
