The device comprises a sulfur dioxide water solution collector, an aeration tower, an aeration pump and a sulfur dioxide collector, wherein the sulfur dioxide water solution collector is connected to the liquid inlet of the aeration tower; the gas outlet of the aeration tower is connected with the sulfur dioxide collector; the aeration tower is connected with the aeration tower.
Description
Technical field
The utility model relates to a kind of desulphurization plant, particularly relate to a kind of device that overflows sulfur dioxide for Aqueous Solution of Sulfur Dioxide aeration, being mainly used in steel plant, coking plant, power-plant flue gas utilizes the process unit of dew-point temperature desulphurization denitration to collect the Aqueous Solution of Sulfur Dioxide obtaining, by regulating pH value, the temperature of Aqueous Solution of Sulfur Dioxide, pressure, obtain the mist of sulfur dioxide and oxygen, with the source of the gas of later workshop section sulfuric acid processed.Background technology
At present, flue gas desulfurization technique mainly contains limestone-gypsum method, lime-gypsum method (accounting for more than 95%) etc., though effective smoke treatment desulphurization problem to a certain extent, large to desulfurization material demand, and come can produce carbon dioxide in source procedure, and then also environment is had to side effect.
According to 12 requirements of plans of China, whole nation sulfur dioxide annual emissions is 2,600 ten thousand tons, as use lime-gypsum method desulfurization to need 1.32 hundred million tons, lime, lime calcining produces 6,200 ten thousand tons of carbon dioxide, produce 2.7 hundred million tons of chemical gypsums, the carbon dioxide of discharge causes " greenhouse effects ", can bring very large pressure to environment, the chemical gypsum producing does not have value and more difficult, and landfill process is polluted soil body resource and polluted underground water.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of making simply, and automaticity is high, the Aqueous Solution of Sulfur Dioxide aeration desulfurizer of control system safety, energy-conserving and environment-protective.
For reaching above-mentioned purpose, the utility model comprises Aqueous Solution of Sulfur Dioxide collector, aeration tower, aeration pump and sulfur dioxide collector, described Aqueous Solution of Sulfur Dioxide collector leads to described aeration tower liquid inlet, described sulfur dioxide collector is led in described aeration tower gas outlet, and described aeration pump leads to described aeration tower.
Wherein also comprise Aqueous Solution of Sulfur Dioxide flow controller, described Aqueous Solution of Sulfur Dioxide flow controller is between described Aqueous Solution of Sulfur Dioxide collector and described aeration tower.
Wherein said aeration tower gas outlet is positioned at described aeration tower top.
Wherein said aeration pump leads to described aeration tower bottom.
Wherein also comprise automatic voltage-regulating controller, described automatic voltage-regulating controller is connected in described aeration tower side wall upper part.
Wherein said aeration tower bottom is provided with uniform aeration dish, and described aeration plate connects described aeration pump.
Wherein also comprise and adjust oxygen device, described tune oxygen device leads to described sulfur dioxide collector.
The utility model difference from prior art is that the utility model obtained following technique effect:
1, this device is according to the physical property of Aqueous Solution of Sulfur Dioxide and chemical property, regulate pH value to make solution acidifying form the saturated solution of sulfur dioxide, regulate uniform temperature, control certain pressure, sulfur dioxide gas is overflowed, obtain the mist of rear workshop section sulfuric acid processed, improve the efficiency that Aqueous Solution of Sulfur Dioxide overflows sulfur dioxide gas.
2, this device has adopted automatic control system, controls pressure, temperature, the pH value of aeration tower, reaches the optimum condition of sulfur dioxide aeration, makes the efficiency that Aqueous Solution of Sulfur Dioxide overflows sulfur dioxide gas reach best.And this device is made simple, and automaticity is high, and control system is safe, energy-conservation.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: 1-Aqueous Solution of Sulfur Dioxide flow controller; 2-aeration tower; 3-aeration pump; 4-uniform aeration dish; 5-automatic pressure controller; 6-sulfur dioxide collector; 7-adjusts oxygen device; 8-leakage fluid dram.
The specific embodiment
Below in conjunction with drawings and Examples, technical characterictic and the advantage with other above-mentioned to the utility model are described in more detail.
Aqueous Solution of Sulfur Dioxide aeration as shown in Figure 1 overflows the device of sulfur dioxide, Aqueous Solution of Sulfur Dioxide flow controller 1 liquid outlet connects aeration tower 2 inlets, leakage fluid dram 8 is arranged at aeration tower 2 bottoms, aeration tower 2 inner bottom parts are provided with uniform aeration dish 4, uniform aeration dish 4 connects aeration pump 3, aeration tower 2 side wall upper part Bonding pressure automatic controllers 5, sulfur dioxide collector 6 is led in aeration tower 2 gas outlets, top, sulfur dioxide collector 6 is connected with adjusts oxygen device 7, obtain the mist of sulfur dioxide and oxygen, for the mist of rear workshop section sulfuric acid processed.
With reference to Fig. 1, the Aqueous Solution of Sulfur Dioxide that is adjusted to certain pH value in Aqueous Solution of Sulfur Dioxide collector regulates certain flow to enter after aeration tower 2 through Aqueous Solution of Sulfur Dioxide flow controller 1, evenly passed into the air of certain flow to 2 ends of aeration tower through uniform aeration dish 4 by aeration pump 3, because pressure increases, in Aqueous Solution of Sulfur Dioxide, sulfur dioxide is saturated, and sulfur dioxide just overflows from Aqueous Solution of Sulfur Dioxide; The sulfur dioxide overflowing is collected in sulfur dioxide collector 6, then adjust oxygen device 7 to regulate oxygen to enter sulfur dioxide collector 6, obtain the mist of sulfur dioxide and oxygen, for the mist of rear workshop section sulfuric acid processed, while needing step-down, controlled pressure automatic controller 5, gas in tower is discharged through upper pressure automatic controller 5, in the time that needs boost, aeration pump 3 aerations, extraneous air passes into 2 end of aeration tower aeration through uniform aeration dish 4, circulation successively, and the liquid after aeration is complete is discharged by the leakage fluid dram of aeration tower 2 bottoms.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
