Technical field
The invention belongs to environmental protection equipment technical field.
Background technology
At present, be directed to existing biofiltration purifier, active carbon adsorption, UV photodissociation method or other some chemical treatment methods of substantially all adopting of foul gas processing that industrial production produces, and generally all adopt individual equipment to process, and some chemical agents of interpolation therein that can be suitable, have so not only increased human and material resources, have also greatly increased the investment of engineering.For odor treating device, although said apparatus was also carried out to improvement in order to reach better deodorizing effect, also substantially keep above-mentioned basic principle and structure.Deodorizing effect does not significantly improve.
Summary of the invention
The object of the invention is: a kind of foul gas and industrial waste gas purifying treating apparatus are provided, and it can carry out environmental protection treatment to foul gas and industrial waste gas simply and effectively.
Technical scheme of the present invention is: the present invention is mainly comprised of UV photodissociation device, spray deodorizing tower.
In UV photodissociation device, air door is communicated with the import of UV photodissociation device case by demister, and the outlet of UV photodissociation device case is communicated with the import of spray deodorizing tower by centrifugal induced draught fan; Ultraviolet lamp tube is fixed in UV photodissociation device case by support.
In spray deodorizing tower, spray deodorizing tower bottom is water tank, and middle part is packing area, and top is provided with chemical spraying device shower nozzle and deodorization device successively, and top is provided with discharge duct, and chemical spraying device shower nozzle is communicated with acid-base groove by circulating pump.
Several to tens of ultraviolet lamp tubes are fixed in UV photodissociation device case side by side by support.
In spray deodorizing tower, the filler of packing area is Raschig ring Ball-type packing.
The invention has the beneficial effects as follows: 1, efficiently except stench, due to this device strong modularity, and scientific structure, rationally distributed, can efficiently remove peculiar smell and bacterium in gas, treatment effeciency reaches as high as more than 99%.2, technique is succinct, and equipment operating is simple, convenient, without personal management.3, strong adaptability, can adapt to high concentration, large capacity mixed gas purified treatment, can every days 24 continuous throughout the twenty-four hour24, stable and reliable operation.4, operating cost is low, because this covering device flow process is simple, air resistance coefficient is little, without personal management and regular maintenance, only needs to make regular check on, thereby has greatly reduced operating cost.5, non-secondary pollution residue, odorant is by being converted into H in photodissociation equipment 2o, CO 2deng material, without other materials, originate in chemical reaction, meet environmental protection and modern management requirement.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present invention.
The specific embodiment
Embodiment 1
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in the figure, the 1st, air door, the 2nd, demister, the 3rd, UV photodissociation device case, the 4th, ultraviolet lamp tube, the 5th, support, the 6th, centrifugal induced draught fan, the 7th, deodorization and washing tower, the 8th, packing area, the 9th, acid-base groove, the 10th, circulating pump, the 11st, spray pipeline, the 12nd, shower nozzle, the 13rd, water tank, the 14th, blow-off line, the 15th, Automatic Dosing pump, the 16th, PH controller, the 17th, liquid level gauge, the 18th, deodorization device, the 19th, discharge duct.
Foul gas or workshop industrial waste gas are by collecting after mouthful collection, by blower fan, by air door 1, send into demister 2, after enter in rectangle UV photodissociation device 3, according to the composition of gas and concentration, in UV photodissociation device, arrange many row's ultraviolet lamp tubes 4, ultraviolet lamp tube is fixed on support 5, and support housing is provided with aluminum metal silk.By ultraviolet lamp tube, radiate the ultraviolet light of C-wave band, utilize the stronger principle of shorter its photon energy of ultraviolet wavelength, make it have enough energy to produce free radical, cause physics, the chemical reaction of series of complex.Make organic matter under the effect of ultraviolet light, progressively be oxidized to low molecule intermediate product and finally generate CO 2, H 2o and other ion are as NO 3-, PO 4 3-, Cl -deng.
Key reaction mechanism: primary electron obtains acceleration in electric field, clashes into airborne oxygen molecule.The rapid ionization of oxygen molecule when energy surpasses the ionization potential of oxygen molecule.The oxygen molecule that loses electronics becomes positive polarity oxonium ion (O 2 +), and the electronics discharging is combined and is become negative polarity oxonium ion (O with another neutral oxygen molecule 2 -), result is the polarization of oxonium ion and adsorbs neutral oxygen molecule formation O 2 +, O 2 -, O 2the cluster ion of assembling Deng oxygen, has extremely strong oxidisability, can by the harmful components oxidation Decomposition in contaminated air, be harmless product and water in a short period of time.
Gas after UV photodissociation device is processed enters in cylindrical spray deodorization and washing tower 7 by centrifugal induced draught fan 6.Spray deodorization and washing tower is followed successively by from top to bottom: water tank 13, packing area 8, chemical spraying device shower nozzle 12, plant gel deodorization device 18 and discharge duct 19.Spray deodorization and washing tower is processed waste gas and is mainly contained two processes, that is: one, the washing process of acid solution or alkali lye, and two, plant extraction liquid catches, parcel deodorising process.
The waste gas that enters spray deodorization and washing tower adopts gas-liquid conversed absorption pattern to process, gas is through packing area 8, filler adopts Ball-type packing, be positioned at the middle part of scrubbing tower, and acid, alkali lye is stored in acid-base groove 9, makes acid, alkali lye fully contact, react in packing area with gas through circulating pump 10 and spray pipeline 11 by shower nozzle 12.Shower nozzle is positioned at the top of packing area, is convenient to spray medicine even, and it can fully be contacted with gas.Because need waste gas to be processed carries out there is NO in photochemical reaction product 2, SO 2deng, these materials are dissolved in the water tank 13 of spray deodorization and washing tower, and water tank is positioned at the bottom of spray deodorization and washing tower, and will regularly by blow-off line 14, discharge impurity.The substance that is dissolved in spray deodorization and washing tower manifests certain acidity, has a small amount of ozone in UV photolytic product simultaneously, and this material is water-soluble has strong oxidizing property.So also there is a series of acid-base neutralization, redox complex chemical reaction in spray deodorization and washing tower.In order more thoroughly to remove the harmful substance in waste gas, the acid-base value in the time of can normally moving according to scrubbing tower, suitably adds corresponding alkali acid solution, and this process is by Automatic Dosing pump 15, PH controller 16 and liquid level gauge 17 Automatic Control.
In order to make the gas odor concentration after processing lower, this device has increased vegetation water deodorizing facility, the gas of crossing through peracid, neutralizing treatment is by plant gel deodorization device 18, plant gel deodorization device is positioned at the top of shower nozzle 12, to a small amount of residual foul smell composition catch, parcel, final settlement even decompose.
Vegetation water particle is natural oiliness deodorization molecule, and this particle, by intermolecular apolar interaction and foul smell molecule, non-covalent combination occurs, thereby greatly stablizes this quasi-molecule, reduces its activity and excitant.And then the increase due in conjunction with rear proportion, solves by settlement action.This process had both been different from chemical reaction process and had generated the third material, was also different from the effect of covering, and can not cause secondary pollution, can thoroughly remove stink.
Gas is after treatment by discharge duct 19 high altitude discharges.
