Description

Foul gas and organic waste gas purifying processing device
Technical field
The invention belongs to technical field of environment protection equipment.
Background technology
At present, the foul gas process being directed to industrial production generation substantially all adopts biofiltration purifier, active carbon adsorption, UV photodissociation method or other some chemical treatment methods, and generally all adopt individual equipment to process, and some chemical agents of interpolation wherein that can be suitable, which not only adds human and material resources, also greatly increases the investment of engineering.For foul gas processing unit, although also carried out improvement to reach better deodorizing effect to said apparatus, the also above-mentioned general principle of basic maintenance and structure.Deodorizing effect does not significantly improve.
Summary of the invention
The object of the invention is: provide a kind of foul gas and industrial waste gas purifying treating apparatus, it can carry out environmental protection treatment to foul gas and industrial waste gas simply and effectively.
Technical scheme of the present invention is: be made up of UV photodissociation device, spray deodorizing tower.
In UV photodissociation device, air door is by demister and UV photodissociation device case inlet communication, and the outlet of UV photodissociation device case is by centrifugal induced draught fan and spray deodorizing tower inlet communication; Ultraviolet lamp tube is fixed in UV photodissociation device case by support.
In spray deodorizing tower, be water tank bottom spray deodorizing tower, 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.
In spray deodorizing tower, the filler of packing area is Raschig ring Ball-type packing.
The invention has the beneficial effects as follows: l, efficiently except stench, due to this device strong modularity, and scientific structure, rationally distributed, efficiently can remove the peculiar smell in gas and bacterium, treatment effeciency reaches as high as more than 99%.2, concise in technology, equipment operating is simple, convenient, without the need to personal management.3, strong adaptability, can adapt to high concentration, Large Copacity mixed gas purified treatment, can every day 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 the need to personal management and regular maintenance, only need make regular check on, thus greatly reducing operating cost .5, non-secondary pollution residue, odorant is by being converted into H in photodissociation equipment 20, CO 2deng material, originate in chemical reaction without other materials, meet environmental protection and modern management requirement.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present invention.
Detailed description of the invention
Embodiment 1
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in the figure, l is air door, 2 are demisters, 3 are screen packs, 4 are UV photodissociation device casees, 5 are ultraviolet lamp tubes, 6 are supports, 7 are centrifugal induced draught fans, 8 are deodorization and washing towers, 9 are packing areas, 10 are acid-base grooves, 11 are circulating pumps, 12 are spray pipelines, 13 are shower nozzles, 14 are water tanks, 15 are blow-off lines, 16 are Automatic Dosing pumps, 17 are PH controllers, 18 are liquid level gauges, 19 are deodorization devices, 20 is discharge ducts.
Foul gas or workshop industrial waste gas are by collecting after mouth collects, demister 2 is sent into by air door l by blower fan, enter in rectangle UV photodissociation device 4 after the large particulate matter in waste gas being filtered by screen pack 3, in UV photodissociation device, many row's ultraviolet lamp tubes 5 are arranged according to the composition of gas and concentration, ultraviolet lamp tube 5 is fixing on the frame 6, and support housing is provided with aluminum metal silk.By the ultraviolet light of ultraviolet lamp tube radiation C-wave band, utilize the principle that ultraviolet wavelength its photon energy shorter is stronger, make it have and enough can produce free radical most, cause physics, the chemical reaction of series of complex.Make organic matter progressively be gasificated into low molecule intermediate product in the effect fore-telling of ultraviolet light and finally generate H 20, CO 2and other ion is as NO 3 -, PO 4 3-, Cl -deng.
Key reaction mechanism: primary electron obtains acceleration in the electric field, clashes into the oxygen molecule in air.The rapid ionization of oxygen molecule when energy exceedes the ionization potential of oxygen molecule.The oxygen molecule losing electronics becomes positive polarity oxonium ion (0 2 +), and the electronics of release is combined with another neutral oxygen molecule and becomes negative polarity oxonium ion (0 2 -), result is the polarization of oxonium ion and adsorbs neutral oxygen molecule formation O 2 +, O 2 -, O 2deng the cluster ion that oxygen is assembled, having extremely strong oxidisability, can be harmless product and water by the harmful components oxidation Decomposition in contaminated air in a short period of time.
Gas after the process of UV photodissociation device is entered by centrifugal induced draught fan 7 in cylindrical spray deodorization and washing tower 8.Spray deodorization and washing tower is followed successively by from top to bottom: the shower nozzle 13 of water tank 14, packing area 9, chemical spraying device, plant gel deodorization device 19 and discharge duct 20.Spray deodorization and washing tower process waste gas mainly contains 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 entering spray deodorization and washing tower adopts gas-liquid conversed absorption pattern process, gas is through packing area 9, filler adopts Ball-type packing, be positioned at the middle part of scrubbing tower, and acid, alkali storage in acid-base groove 10, through circulating pump 11 and spray pipeline 12 makes acid by shower nozzle 13, alkali lye fully contacts in packing area with gas, react.Shower nozzle is positioned at the top of packing area, is convenient to spray medicine even, enables it fully contact with gas.Carry out there is NO in photochemical reaction product owing to needing waste gas to be processed 2, SO 2deng, these materials are dissolved in the water tank 14 of spray deodorization and washing tower, and the bottom of spray deodorization and washing tower is done in water tank position, and regularly will discharge impurity by blow-off line l5.The substance being dissolved in spray deodorization and washing tower manifests certain acidity, and have few ozone in UV photolytic product, this material is water-soluble has strong oxidizing property simultaneously.So also there is a series of acid-base neutralization, redox complex chemical reaction in spray deodorization and washing tower.In order to more thoroughly remove the harmful substance in waste gas, acid-base value when normally can run according to scrubbing tower, suitably add corresponding alkali acid solution, this process is by Automatic Dosing pump 16, PH controller 17 and liquid level gauge 18 Automatic Control.
In order to make the gas odor concentration after process lower. this device adds vegetation water deodorizing facility, the gas crossed through peracid, neutralizing treatment is by plant gel deodorization device 19, plant gel deodorization device is positioned at the top of shower nozzle 13, catches, wraps up, final settlement even decomposes to a small amount of residual foul smell composition.
Vegetation water particle is natural oil deodorization molecule, and this particle by intermolecular apolar interaction and foul smell molecule generation Non-covalent binding, thus stablizes this quasi-molecule greatly, reduces its active and excitant.And then due to the increase in conjunction with rear proportion, solved by settlement action.This process is both different from chemical reaction process and generates the third material, is also different from the effect of covering, and can not cause secondary pollution, thoroughly can remove stink.
Gas is after treatment by discharge duct 20 high altitude discharge.
