Between contracting section, 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 leads to
Cross bend pipe 5 to be connected with equilibrium reflux pipeline 3, equilibrium reflux pipeline 3 is connected with absorbent reflux pipeline 4, absorbent reflux pipeline 4
The other end and absorber portion accumulator tank connect.
As shown in figure 1, in the utility model, save-all for spillage 2 is 0.3 meter to 2 meters with rising the distance between gas cap 1 scope
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 received with leakage
Enough gaps is left between storage 2 and ensures that flue gas can be smooth uniformly through big from atomization shape absorbent circulation fluid and during low pressure
Part can also be reclaimed by save-all for spillage 2.
As shown in figure 1, bend pipe 5 is set between save-all for spillage 2 of the present utility model and equilibrium reflux pipeline 3, bend pipe 5
Setting may insure that in high pressure normal operation pending high pressure flue gas flows into absorbent without going past equilibrium reflux pipeline 3
Reflux pipeline 4.
As shown in Figures 2 and 3, save-all for spillage 2 of the present utility model includes liquid holding groove 21, loudspeaker collection port 22, water conservancy diversion
Groove 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, loudspeaker
Collection port 22 has multiple apertures, and floating window 27 is set on each aperture.So, when pending flue gas pressures step-down, float
Dynamic window 27 covers the aperture of loudspeaker collection port 22, and the flue gas feed pressure of both sides becomes big, so that absorber portion floats into enriching section
Atomization shape absorbent circulation fluid can be reclaimed by liquid holding groove 21, so may insure be atomized shape absorbent circulation fluid will not be elegant
And then leakage is formed, 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 stream
Enter absorber portion.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 is set
Floating block bayonet socket 26 is put, floating block 25 is set in floating block bayonet socket 26.So, when flue gas is high pressure, liquid will not be formed in liquid holding groove 21
Body, floating block 25 block guiding gutter 23, it is ensured that gases at high pressure will not export from liquid outlet 24, when flue gas air pressure is relatively low, contain
The meeting withdrawal liquid of liquid bath 21, when liquid is more, floating block 25 floats upwards, automatic discharging function.
As shown in figure 1, equilibrium reflux pipeline 3 of the present utility model preferably tilts down setting, the liquid so to flow back can
With by by gravity reflux.
As shown in Figure 1, Figure 2 with shown in Fig. 5, floating block 25 of the present utility model it is preferably provided as spheroidal, because below 30 °,
The liquid that the utility model is reclaimed contains certain sulfurous acid ammonia, and when temperature is relatively low, floating block 25 may be by the high knot of concentration
