Two, odor-removing oxygen-enriched technological process of the present invention and operation, see accompanying drawing 1 for details:

The ozone that is produced by (101) ozonator detect through (102) in the usefulness ozone effusion meter detectable concentration qualified after, quantitatively after quantitatively, input (2) ozone and tail gas mixing tube (Venturi tube) in the meter through (1) ozone again, ozone is with after tail gas mixes, enter (4) reative cell and ozone decomposed chamber by (3) mist air inlet pipe, there is oversaturated calcium hydroxide alkali liquor this chamber, at this ozone gas with foreign flavor such as hydrogen sulfide, sulfur dioxide, the oxidations such as ammonium sulfide, the ozone killing bacteria, calcium hydroxide alkali liquid corrosion dissolution of bacteria cell or dead bacterium corpse segment are removed abnormal flavour; Simultaneously owing to oxynitride dinitrogen pentoxide, nitrogen trioxide dissolubility in this alkali liquor are the thousands of times of carbon dioxide, nitrogen oxide is divided, and the reaction of fermentation thalline exhalation abnormal flavour carbon dioxide itself generates precipitation of calcium carbonate, and is jointly removed the abnormal flavour of the carbon dioxide of thalline exhalation by ozone and calcium hydroxide alkali liquor.Ga in the reactant liquor ²⁺Constantly soluble in water additional by emulsifying shape calcium hydroxide in the water.(5) cover cap and cover plate cover the regional reative cell that is, this zone is outer to be the ozone decomposed chamber, the complete ozone of unreacted decomposites oxygen in water liquid, make the tail gas of removing abnormal flavour become aseptic oxygen-enriched air, and rotate into (6) aseptic oxygen-enriched air except hydroecium from tangential direction, tube wall and rotating separation effect because bump is given vent to anger, in the discharging tube of cyclone separator bottom, flow in the alkali liquor under the water droplet, gas from then on cyclone separator escape pipe lower port enters, from the unexpected swelling heat absorption condensation of escape pipe upper port, further dewater, be discharged to (7) aseptic oxygen-enriched air discharge chamber, be discharged to outdoor, in the alkali liquor of mixed gas reaction chamber, every batch fermentation is complete by (10) condensate return pipe flow for the water that discharge chamber agglutinates, and (9) feed opening blind flange is pulled down, mixed gas reaction chamber alkali liquor and solid grain piece can be removed, and remove mixed gas reaction chamber liquid and solid grain piece complete.The liquid of clearing out of is used for reclaiming lime nitrate, and the solid of clearing out of is refitted in the logical carbon dioxide solution, and calcium carbonate becomes the calcium bicarbonate dissolving, and calcium sulfate is insoluble, separates to get calcium sulfate, and calcium bicarbonate solution prepares solid carbonic acid hydrogen calcium with well-established law again.Sealing feed opening blind flange.Add entrance (i.e. reinforced hand hole) in (8) solid reactants again and add solid oxidation calcium in the water of (4) reative cell and ozone decomposed chamber.Water adds tap water in (4) reative cell and ozone decomposed chamber from (11) filler pipe, the limit adds the waterside and adds calcium oxide, after calcium oxide all becomes calcium hydroxide, adjust again and add water, be added to (12) overflow pipe outflow water retention and add water, the sealing charge door is treated down to criticize except fermentation tail gas abnormal flavour and degerming usefulness, and (4) reative cell and ozone decomposed chamber become good aseptic fluid-tight chamber at this moment.

Three, reaction principle:

(1) air reacts under electric spark:

Airborne oxygen ozonize: 3O ₂→ 2O ₃, O ₃→ O ₂+ [O]

Airborne nitrogen becomes dinitrogen pentoxide: 2N ₂+ 5[O] → 2N ₂O ₅

(2) the ozone reaction that eliminates the unusual smell:

O ₃→O ₂+[O]

[O] is strong oxidizer;

[O]+bacterial cell or its corpse segment → scentless oxidation product

[O]+amines → N ₂+ NO ₂

[O]+H ₂S→SO ₃+H ₂O

[O]+[NH ₄] ₂S→SO ₃+NO ₂+H ₂O

[O]+2NO ₂→N ₂O ₅

(3) react in the alkali liquor:

O ₃+H ₂O→H ₂O ₂+O ₂→H ₂O+O ₂+[O]

H ₂O ₂The above-mentioned reaction that eliminates the unusual smell of [O] is arranged equally.As seen the ozone ability that eliminates the unusual smell in aqueous solution is stronger, because the H of ozone generating ₂O ₂Can produce more [O], the ability that eliminates the unusual smell is stronger.

CaO+H ₂O→Ca(OH) ₂→Ca ²⁺+2OH ^-

OH ^-The materials such as+bacterial cell and fragment oxidation product → water soluble peptide, aminoacid

SO ₃+H ₂O→H ₂SO ₄

H ₂SO ₄+Ca ²⁺+2OH ^-→CaSO ₄↓+2H ₂O

N ₂O ₅+H ₂O→2HNO ₃

HNO ₃+OH ^-→NO ₃ ^-+H ₂O

CO ₂+2OH ^-→CO ² ₃ ^-+H ₂O

Ca ²⁺+CO ₃ ^2-→CaCO ₃↓

But as seen calcium sulfate and precipitation of calcium carbonate and lime nitrate natural separation in solution.Reclaim lime nitrate in solution, calcium carbonate and calcium sulfate can place logical carbon dioxide liquid again, and it is water-soluble that calcium carbonate becomes calcium bicarbonate, and calcium sulfate is insoluble and both separate.Calcium bicarbonate liquid is again with industrial legal system solid carbonic acid hydrogen calcium commonly used.

CaCO ₃+CO ₂+H ₂O→2Ca(HCO ₃) ₂

(4) unnecessary ozone decomposed discharges the oxygen reaction:

O ₃→O ₂+[O]

2[O]→O ₂

W＝V×1.3×20.9％×2％×η×60×h

W: the amount of carbon dioxide that whole fermentation period is removed, kg;

V: the amount of tail gas, m are discharged in fermentation ³/ min;

η: removing carbon dioxide efficient; 70%-99.9%;

H: whole fermentation period time.

5.2 required calcium oxide content calculates:

Reaction equation: CaO+H ₂O → Ca ^2*+ 2OH ^-

CO ₂+2OH ^-+Ca ²⁺→CaCO ₃↓+H ₂O

That is: CaO+CO ₂→ CaCO ₃↓
