Background technology
In current environmental protection under the new situation, atmosphere pollutants emission standardses are increasingly strict.Ammonia type flue gas desulfurizing technology extensively should
For the industry treating tail gas such as sulfuric acid, boiler, coking.The high-temperature flue gas that boiler combustion is produced enters desulfurizing tower after being pressurized through blower fan
The enriching section at middle part.By spray, washing, after cooling, top absorber portion is entered back into.The flue gas of absorbent from top to bottom with rising
SO2 in counter current contacting, flue gas generates ammonium sulfate, ammonium bisulfite etc. with the reaction of absorbent circulation fluid, and the SO2 in flue gas is able to
Removing purification, the flue gas after desulfurization is up to standard is discharged by chimney.Absorbent is sent to the atomization of desulfurizing tower absorber portion after being pressurizeed through circulating pump
Spray reaction, starts shipment when boiler, stops transport and during load down production, boiler smoke tolerance will be greatly lowered, and flue gas passes through desulfurization
Tower rises the pressure head reduction at gas cap position, causes atomization shape absorbent circulation fluid to be floatd from a liter gas cap position and drains to the concentration of desulfurizing tower
Section, as the pump operating cycle time elapses, leakage cumulative amount is constantly deepened, and absorbent circulating slot liquid level constantly declines, and sulfuric acid
Ammonium circulating slot liquid level constantly rises, and causes the circulating fluid volume disequilibrium in absorbent circulating slot and ammonium sulfate circulating slot, so that
Influence ammonia type flue gas desulfurizing system process is normally carried out.

Embodiment
Technical scheme is described further below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, ammonia type flue gas desulfurizing circulation fluid of the invention optimization bascule includes rising gas cap 1, leakage
Collector 2, equilibrium reflux pipeline 3, absorbent reflux pipeline 4, bend pipe 5, rise gas cap 1 and are arranged on desulfurizing tower absorber portion and enriching section
Between, save-all for spillage 2 is arranged on enriching section, and positioned at the position directly below of gas cap 1 is risen, the bottom of save-all for spillage 2 passes through curved
Pipe 5 is connected with equilibrium reflux pipeline 3, and equilibrium reflux pipeline 3 is connected with absorbent reflux pipeline 4, absorbent reflux pipeline 4 it is another
The accumulator tank connection of one end and absorber portion.
As shown in figure 1, in the present invention, save-all for spillage 2 with rise the distance between gas cap 1 scope be 0.3 meter to 2 meters it
Between, save-all for spillage 2 is with rising preferably 0.5 meter of the distance between gas cap 1, during such high pressure, rises the bottom of gas cap 1 and is collected with leakage
Enough gaps is left between device 2 and ensures that flue gas can be smooth uniformly through and during low pressure, from the big portion of atomization shape absorbent circulation fluid
Dividing can also be reclaimed by save-all for spillage 2.
As shown in figure 1, setting bend pipe 5, the setting of bend pipe 5 between the save-all for spillage 2 and equilibrium reflux pipeline 3 of the present invention
It may insure when high pressure is normally run, pending high pressure flue gas flows into absorbent backflow without going past equilibrium reflux pipeline 3
Pipeline 4.
As shown in Figures 2 and 3, save-all for spillage 2 of the invention include liquid holding groove 21, loudspeaker collection port 22, guiding gutter 23,
Liquid outlet 24, floating block 25, floating block bayonet socket 26, floating window 27, the top of liquid holding groove 21 set loudspeaker collection port 22, and loudspeaker are collected
Mouth 22, which has, sets floating window 27 on multiple apertures, each aperture.So, when pending flue gas pressures step-down, floating window 27
The aperture of loudspeaker collection port 22 is covered, the flue gas feed pressure of both sides becomes big, so that absorber portion floats into the atomization of enriching section
Shape absorbent circulation fluid can be reclaimed by liquid holding groove 21, so may insure that atomization shape absorbent circulation fluid will not elegant and then shape
Into leakage, the liquid of recovery is flowed into liquid holding groove 21；When flue gas pressures are high, floating window 27 is opened, and is easy to flue gas to flow into absorption
Section.The bottom of liquid holding groove 21 sets guiding gutter 23, and the side of guiding gutter 23 sets liquid outlet 24, and the top of guiding gutter 23 sets floating block
Floating block 25 is set in bayonet socket 26, floating block bayonet socket 26.So, when flue gas is high pressure, liquid, floating block will not be formed in liquid holding groove 21
25 block guiding gutter 23, it is ensured that gases at high pressure will not be exported from liquid outlet 24, when flue gas air pressure is relatively low, the meeting of liquid holding groove 21
Withdrawal liquid, when liquid is more, floating block 25 floats upwards, automatic discharging function.
Set as shown in figure 1, the equilibrium reflux pipeline 3 of the present invention is preferably downward-sloping, the liquid so flowed back can lead to
Cross by gravity reflux.
As shown in Figure 1, Figure 2 with shown in Fig. 5, floating block 25 of the invention it is preferably provided as spheroidal, because below 30 °, this hair
Bright reclaimed liquid contains certain sulfurous acid ammonia, when temperature is relatively low, and floating block 25 may be pasted by the high crystalline solid of concentration
When firmly, and then when flowing liquid into can not in time open, and use spheroidal, can reduce floating block 25 and guiding gutter 23 connects asperities
Product, enables the liquid of high temperature quickly to dissolve crystalline solid, it is ensured that floating block 25 can float.
As the further scheme of the present invention, as shown in Figure 1, Figure 2 with shown in Fig. 5, the present invention sets up memory in guiding gutter 23
Alloy sheet 28, shape memory alloy 28 is opened when temperature is less than 30 °, during in open mode, the opposite side of shape memory alloy 28
Floating block 25 is supported on, natural closure state is in when higher than 30 °, now shape memory alloy 28 is not contacted with floating block 25.This
Sample, during work of the invention, even if flue gas air pressure is relatively low, the operating temperature of save-all for spillage 2 can also be higher than 30 °, so note
Recall alloy sheet 28 to close, as shown in Fig. 2 now, if any save-all for spillage 2 built with liquid, then floating block 25 floats, such as without liquid
Body, then floating block 25 can block guiding gutter 23, it is ensured that flue gas will not enter absorbent reflux pipeline 4.During without working, temperature may
Less than 30 ° are reduced to, now sulfurous acid ammonia liquid may be crystallized, but now shape memory alloy 28 can be in open mode, such as Fig. 5
It is shown, floating block 25 is above pushed away, even if crystallization, also can guarantee that floating block 25 will not block guiding gutter 23, and do not having in harness situation
Under, there will not be flue gas, so when accreditation ensure that flue gas does not enter absorbent reflux pipeline 4.
Optimize balance method the invention also discloses a kind of ammonia type flue gas desulfurizing circulation fluid, leakage is set below liter gas cap
Collector, rising has certain interval between gas cap and save-all for spillage, the liquid of save-all for spillage is back to absorbent backflow
In pipeline, save-all for spillage be provided with gas port, when flue gas be high pressure, flue gas from save-all for spillage and rise gas cap between interval and
Gas port flows into absorber portion；When flue gas air pressure is reduced, the air guide bore closure of save-all for spillage, flue gas is flowed to from surrounding to be absorbed
Elegant atomization shape absorbent circulation fluid is absorbed by save-all for spillage 2 in section, absorber portion, and flows into absorbent reflux pipeline 4.
