From the 200mg/m of standard GB/T 13223-20113Near 35mg/m3Below.At present, the conventional limestone Gypsum Fibrosum of application takes off
Sulfur technique uses the single pH value of single column spray to control, and desulfuration efficiency is generally 95%, relies on simple amplification conservative design, difficult
To meet new emission control requirement, and there is construction and run uneconomical, the problems such as adaptability for working condition is poor.
According to the further investigation of desulphurization mechanism and analysis, when in desulfurizing tower slurry pH value control low interval time, can carry
High liquid phase reactor speed, accelerates the dissolving of absorbent limestone, promotes the oxidation of by-product Gypsum Fibrosum and crystallization, after being beneficial to washing
The stable curing of sulfur dioxide and salt-forming conversions, promote desulfurization.Serosity can be improved to flue gas when pH value controls in high interval
The washing absorption speed of middle sulfur dioxide.Traditional single column list pH value controls to look for a relative compromise between height pH
Span of control, it is impossible to thoroughly solve this contradiction.At present, domestic use single column double circulation desulphurization tower use conical bottom collect bowl with
Serosity deflector, blocking-up shock effect that flue gas is through-flow is obvious, and flow transition is the most smooth and easy, distributing homogeneity is poor, causes flue gas to lead to
Flow resistance is big, and air and gas system energy consumption is significantly increased.It is thus desirable to exploitation one can be taken into account by high and low pH value zonal control simultaneously,
Homogenizing flow field is to reduce the technology and equipment of flue gas flow passage resistance, it is achieved desulfurization low energy consumption puies forward effect further, adapts to new environmental protection
Emission request.
Summary of the invention:
The present invention develops a kind of combination unit designing uniqueness, is mainly used in sulfur removal technology double pH spray desulfurizing tower cleaning mixture
The rectification of flue gas is risen in drain, and desulfurizing tower.

Bottom connects serosity pipeline, the high pH serosity collected is derived the high pH stock tank outside absorption tower, thus low pH starches with in absorption tower
Being effectively isolated of pond, it is achieved double pH value control partition function.The Streamline Design of alms bowl type drip tray is conducive to cigarette from below to up
Gas rounding off and shunting, reduce the resistance that flue gas is through-flow to greatest extent.Airflow design any surface finish simultaneously, has " Folium Nelumbinis " to imitate
The function answered, the slurry droplet that flue gas carries collides its surface and is gathered into rapidly liquid pearl and tumbles, do not stains, and also can profit
Flue gas carried may the serosity that adheres to of collision and fine grained be carried out with the condensing drip of saturated wet flue gas curding out, real
Existing self-cleaning function.
4, the volume of alms bowl type drip tray is upper strata sprayed slurry 0～100S residence time volumes, arranges height bottom drip tray
PH serosity draws pipeline, and caliber needs to mate with drip tray volume to avoid drip tray serosity overflow.
5, using the present invention, the Optimal Structure Designing of alms bowl type drip tray and wall stream draining ring makes the obstruct of absorption tower section
Effects is lower, and current-sharing and concentration field effect of optimization are more preferable, and flow passage resistance is less.
Test case one:
Certain processes exhaust gas volumn 50,000 m3/ h desulfurization test device, absorption tower spray number of plies configuration is identical, has carried out following several situations
Test compare；
Situation one: void tower, 3 layers of spray, single pH value controls；
Situation two: use double pH spray desulfurizing tower biphase rectification drainage sets of embodiment two, it is achieved pH value subregion, above device
High pH spray equipment arranges one layer, and lower section low pH spray equipment arranges two-layer.
Situation three: use existing tradition single column double circulation desulphurization tower circular cone shown in Fig. 3 (to use conical trays, tower wall
Guide ring is plank frame), remaining experimental condition is similar with situation 2.
Experimental test result such as following table:
| Ratio Relatively | Inlet flue gas Amount, m3/h | Entrance SO2Dense Degree, mg/m3 | Absorption tower Resistance, Pa | Spray is opened Open the number of plies | Desulfurization Effect Rate, % | PH value | Outlet SO2Dense Degree, mg/m3 | Section flow field Speed is inclined Difference, % |
| Feelings Shape One | 41122 | 2500 | 556 | 3 | 95.12 | 4.91 | 122.00 | 18.7 |
| Feelings Shape Two | 41078 | 2651 | 692 | 3 | 99.03 | Low pH4.61, High pH5.81 | 25.71 | 3.56 |
