Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As Figure 1-Figure 2, the utility model proposes a kind of air purification tower, including Venturi scrubber 1, venturi
1 one end of washer connects air inlet 11, and the other end connects absorption tower, and spray system 3,3 lower section of spray system are arranged in absorption tower
Reactor tank 2 is set, and specific current device is arranged above spray system 3 for crystallizing the discharge port being precipitated in the setting of 2 bottom of reactor tank
4, gas outlet 5 is arranged in absorption tower top, and gas outlet 5 connects variable-pressure rectification device 6.
Spray system 3 includes hydraulic pump 7, and pump is connected the trunnion 13 of venturi valve by pipeline, passes through calcium hydroxide cream in pump.
Specifically, fume gases from air inlet 11 enter Venturi scrubber 1, Venturi scrubber 1 include collapsible tube 12,
Trunnion 13 and diffuser 14, after fume gases enter collapsible tube 12, flow velocity increases, and maximum value, liquid are reached when entering trunnion 13
Body enters from trunnion 13, and since the relative velocity difference between gas and liquid is very big, drop is atomized under the action of high-speed flow,
The intracorporal humidity of gas reaches saturation, and the grit in gas is readily wetted by water, collides and agglomerate between grit and drop or grit.
In diffuser 14, gas-liquid speed is reduced, pressure rise, and cohesion is accelerated, and the dust-laden drop being relatively large in diameter is formed, in Wen Qiu
In in washer 1, following chemical reaction occurs:
SO2(gas)+H2O→H2SO3(liquid)
Ca(OH)2(liquid)+H2SO3(liquid) → CaSO3(liquid)+2H2O
Gas-liquid mixture after reaction enters in reactor tank 2,
Specifically, liquid is output to spray shower head by hydraulic pump 7, spray shower head sprays lime hydrate emulsion body, and ejection disappears
Milk of lime liquid with gas-liquid mixture further occurrence is above-mentioned reacts, and converged in the bottom of reactor tank 2, when in drop
CaSO3After reaching saturation, that is, starts crystallization and be precipitated；
CaSO3(liquid) → CaSO3(Gu)
Reactor tank 2 connects oxygen port, is passed through oxygen in oxygen port；CaSO in part solution3With the oxygen being dissolved in drop
Solid/liquid/gas reactions are oxidized to calcium sulfate, and following reaction occurs:
CaSO3(liquid)+1/2O2(liquid) → CaSO4(liquid)
CaSO4(liquid) solubility is low, to crystallize precipitation, on the other hand, inferior sulfate radical is made to become sulfate radical, increases steady
It is qualitative, and CaSO4Easily it is precipitated:
CaSO4(liquid) → CaSO4(Gu)
Solid is discharged from the discharge port of bottom for crystallization.
The connection setting reflux unit of reactor tank 2, reflux unit includes the recovery pump 9 for withdrawal liquid；For recycling not
The liquid reacted completely, it is further provided the multiple reaction recycled to spray system 3.
Specific current device 4 includes multiple electrodes plate, passes through pulse current on electrode plate.
Specifically, pulse current can make the molecule such as O in flue gas2、H2O etc. is in excitation state, ion or cracking, generates strong
Free radical O, OH, HO of oxidisability2And O3Deng.These free radicals are to the SO in flue gas2It is aoxidized with NO, respectively becomes SO3With
NO2Or corresponding acid, then with Ca (OH)2It reacts；
On the other hand, Electrostatic Absorption occurs for the dust in electric current and fume gases, and dust is collected.
Gas outlet 5 connects variable-pressure rectification device 6, including pressurized segment 61, rectifying section 62 and condenser system 63, for recycling reaction
Heterogeneity in gas, it is specific as shown in Figure 2；
Specifically, due to different at the mixture being grouped as, the change of boiling point caused by the variation with pressure is different,
Therefore it is isolated by way of changing pressure, pressure is applied to gas-liquid mixture in present pressurized segment 61, in rectifying section again
62, it is totally separated from by the reflux repeatedly recycled, pure gas is discharged finally by condenser pipe.
A variety of modifications of embodiment will be readily apparent to those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
