Description
Technical field
The utility model relates to a kind of Deodor machine, particularly a kind of process all kinds of sewage treatment plants, pumping plant process and transport wastewater process in the sewage Deodor machine of the foul gas that produces.
Background technology
The odorant producing in sewage disposal process is varied, main foul gas is hydrogen sulfide, ammonia, mercaptan, thioether, organic amine, VOC (VOC) etc., have that foul smell is large-minded, concentration is high, the feature such as complicated component, corrosivity are strong, in industry, existing deodorization technology has following defect when practical application: masking method is not really removed foul smell in principle, but the mode of deception sense of smell is not suitable for prolonged application; The easy saturated inefficacy of absorption method produces secondary pollution simultaneously, can not be for the industry deodorizing; Spray process and bioanalysis can not be processed for water-fast organic matter in this type of foul smell, process this type of foul smell thorough not; This type of foul smell humidity is too large, and fuel value is too low simultaneously, therefore combustion method inapplicable the industry deodorizing; When ultraviolet photolysis technology is applied in the industry, equipment needed thereby volume is too large, fluorescent tube quantity is too many, simultaneously because fluorescent tube short reason in service life causes once dropping into operating cost all very high; Plasma method needs foul smell directly to contact with discharge medium, and easily cure hydrogen and the ammonia corrosion of guiding discharge medium lost efficacy, and this kind equipment structurally and be not suitable for the industry.
Utility model content
In order to address the above problem, the utility model provide a kind of based on resonance quantum coordination technique (SQU) sewage Deodor machine.
SQU refers to resonance quantum coordination technique, and its central principle is " based on the photo-induced molecule fast reaction of low-power " (Low Dencity Light Induce fast Molecular Reaction).This technology is comprised of supercharger unit, quantum exciter unit and three of Photoreactor unit elementary cell, itself has had suitable deodorizing and oxidability each unit, simultaneously, when three unit are coupled in some way, and when coupled modes meet resonance condition, can act synergistically, the impact of performance is greatly improved, experimental results show that and generally can obtain several ten thousand times to hundreds of thousands effect doubly.
Supercharger unit
This technology is based on " three cross surfaces electric discharge " electron excitation device, different from other " dielectric barrier discharge (DBD) ", and this technology has that efficiency is high, object productive rate large, be subject to humiture to affect the features such as little.By high energy electron exciter, produce a large amount of active groups, carry out complicated physical-chemical reaction with pollutant, initator, oxidant, the extraction that the produces high concentration agent of going out.Before arriving next technique, can eliminate part pollutant.By diffusion process, reach homogeneous phase, enter next technique.Because the process of this technology is very complicated, for example, SO only
2, NH
3reactional equation just have 78 more than, therefore slightly explain that its basic process is as follows:
Electric field+electronics → high energy electron
High energy electron ten air → excited atom+ion
High energy electron+pollutant → be excited group+free group+ion
Group+oxygen (oxygen atom, ozone, oxygen, oxonium ion) → product
Oxidation technology based on ozone has been ripe technology, but because the decomposition rate of ozone is lower, time constant is larger, generally can reach 5 hours, so in gas treatment, cannot carry out dynamics Design effectively, reach 90% contaminant removal efficiency, need great power.Meanwhile, also need reactor to have great volume, to guarantee the reaction time.
Quantum exciter unit
Modern scientific research shows, smell is that two characteristics by material are determined, the molecular weight that is material, and for example carbocyclic ring is with the increase of carbon number, and its smell weakens gradually, while reaching 18 carbon, just there is no smell.Two is specific micel, is called odoriphone, such as hydroxyl etc.Cucumber for example H2S itself is exactly odoriphone.Based on this, if can be by the linking of odoriphone decomposition or disconnection and pedestal, material loses smell.Be that we do not need to decompose whole molecule, only need to decompose odoriphone.
Again according to physical basic general knowledge, between the excessive particle of energy difference, can not carry out energy transmission, namely do not absorb, so for different pollutants, need different wavelength.By regulation and control photon energy, can be efficiently except depolluting molecule.For example, for CS
2need 183nm, SO
2need 207nm, NH
3need 175nm etc.For odoriphone, also there is an optimum wave band, we make that by adjustment ultraviolet source odoriphone is had to selective absorption, just smelly material " can be excited ".
Material in excitation state, there is great chemism, modern science shows, on the one hand, the electron orbit of excitation state material is in high n state, and its atomic radius is very large, for example, the highest n value of hydrogen atom can reach 630, and its radius has surpassed the spacing of gas molecule, so collision probability raising is very large; In addition, molecular configuration also can change, and improves collision probability.
For oxidation material and oxidized material, apply and excite simultaneously, so-called " working in coordination with " effect occurs.Under individual cases, likely reach 106 times.
This process, under suitable partner ratio, excites by appropriate power, can reach 99% contaminant removal efficiency.
Reactions steps:
Its basic process is chain reaction, and in this process, chemical reaction is still extremely complicated.
Roughly comprise three class reactions, i.e. chain initiation reaction, free radical transfer reaction and chain termination reaction.
For example:

Hydroxyl free radical has extremely strong oxidisability, and its oxidizing potential, up to 2.06V, is only second to fluorine (2.23V), so can be oxidized most of hard-degraded substance.
Photoreactor unit
This unit, for unreacting substance, carries out secondary excitation, treatment effect can be reached to 99.9%.
If last unit is high energy, excite, this unit belongs to low-lying excitation, is mainly the waveband selection for different material, cannot realize with a kind of element at present under technology.
Another object of this unit is exactly that tail gas decomposes.Because ozone is high energy oxidizer, for Air Close To The Earth Surface, be harmful substance, can cause multiple chain reaction, to around corrosivity is extremely strong, human body is also harmful to simultaneously, so need to be decomposed, make near the ozone content of steam vent reach sanitary standard.
Kinetic description
Above substep is described the function of an equipment part, explains its course of work below from kinetics.
Ozone and product thereof and pollutant carry out chemical reaction, and its reaction rate is defined as v
1.When using certain ultraviolet irradiation pollutant, its reaction rate is v
2.If two techniques are added to same reactor, reaction rate > (v
1+ v
2), this phenomenon is called " cooperative effect ".Although cooperative effect has increased reaction rate, increase multiple limited.When we control a plurality of ultraviolet frequencies and power thereof, make it to meet certain ratio, control the concentration of ozone simultaneously, under other factors participate in, can with certain molecular structure for example " odoriphone " produce the synergy of large multiple.Claim the multiple ultraviolet ray that meets this ratio to meet " resonance condition ".Because multiple ultraviolet ray has comprised tens wave bands of far ultraviolet and VUV, so be referred to as " light quantum ".The exhaust gas treatment technology of applying above principle exploitation is called as " resonance light quantum and ozone and product cooperative effect " technology, is called for short " resonance quantum is collaborative " technology.
Its basic principle is resonant excitation, chain reaction, ozone oxidation and the advanced oxidation etc. in photo chemistry technology.Below divide and chat it:
First be ozone oxidation, the applicating history of existing 100 years, but recently because the breakthrough of ozone generator technology is just used widely, its principle is also elaborated.Its subsequent products for example oxidisability of hydroxyl is also well studied, and is called as high-level oxidation technology.Because it is only second to the oxidizing potential of fluorine, so be widely used in the processing of water and the processing of waste gas.
The effect of light quantum research at present and insufficient, to the mechanism research of " cooperative effect " also without major progress.Except utilizing 185nm wave band to produce low concentration ozone, seem without other application, particularly low intensive ultraviolet light, seldom separately for chemical reaction, this is just the opposite with the situation of Ultra-Violet Laser, and the overwhelming majority's achievement in research is all " only as ".
The mechanism research of " resonance quantum collaborative " technology similarly, but following be what time what to be proved.
1. the reaction cross-section of excited atom increases.For example, the hydrogen-like atom in inner Byrd state, its orbit radius and n
2be directly proportional.Electronics in inner Byrd state does not almost have penetration simultaneously, and similar with free electron, so its collision cross-section is very big, chemical reactivity is high.
2. the molecule being excited, its configuration can change, and has increased reaction cross-section.
3. after certain ultraviolet of Ozone Absorption (254nm), can decompose, but its decomposition rate is relevant with another kind of ultraviolet ray again.Experiment finds that there is an optimal value and exists.Under this optimum state, ozone has maximum chemical activity and the highest kinetic constant.
4. optimal absorption condition of some structural correspondence of pollutant, is called RESONANCE ABSORPTION.For example: for CS
2need 183nm, SO
2need 207nm, NH
3need 175nm etc.The ability of controlling light quantum just can so that pollutant by maximum excitation.
5. chain reaction needs the multiple auxiliary formulations such as initiation, extraction are gone out, gap bridge, and rationally controlling auxiliary formulation obviously can increase reaction rate.
6. in above several situations, the gain constant of each is made as A
i, comprehensive gain is A=∑ A
i.
Obviously, the gain of multiplicative property, has very large numerical value.General simple control just can obtain the gain of nearly thousand times, and control efficiently can obtain hundreds of thousands gain doubly.The half-life of general ozone is 16 hours, and the gain of 100,000 times means second level time, and Here it is can process the principle of dynamics of pollutant in level second in the time.
From the formation in molecular collision cross section, if definition S is collision cross-section:
S＝k×r×n
1×n
2/l
Wherein:
K: kinetic coefficient, for fixing reaction, is constant
R: molecular geometry cross section, depend on the principal quantum number of outermost layer valence electron and molecular configuration.
N: reaction molecular density.
L: free path, depends on the conditions such as gas pressure, temperature, density.
From being used for of this technique, first module has increased n
1value; Second unit has increased the value of r, has reduced the value of l.Owing to being multiplication relation completely in formula, so its collision cross-section is index increase, particularly l with multiplication, while being bordering on zero, cross section infinitely increases, without collision, and directly contact.
Chemical reaction rate is made as J,
J＝S×P/t
P: crash response probability, depends on the chemical potential of valence electron and excites degree.
T: the half-life of oxidant, the speed that for example ozone molecule decomposes.
Unit the second and the 3rd has all increased the value of P, has reduced the value of t, so can significantly improve reaction rate.
The increase of reaction rate, in fact, for kinetics, can reduce system bulk, reduces SR, obviously just can reduce energy consumption, improves treatment effeciency.
We know, different electromagnetic wave bands, for molecule, have no effect.For example infrared have effect of vibration for molecule, microwave section has rotary action for molecule, its collision cross-section of the polar molecule of high speed rotating and reaction rate all can improve a lot, so by the multiband feature of exciter, can effectively increase reaction cross-section and reaction rate.
The advantage of engineering application
General chemical reaction is divided into gas-solid/liquid/gas reactions, gas-liquid reaction, gas-solid reaction.
Obviously, it is the fastest that reaction speed surely belongs to gas-solid/liquid/gas reactions, and gas-liquid reaction takes second place, and gas-solid reaction is the slowest.Reason is that gas-solid/liquid/gas reactions is directly to depend on collision cross-section, is proportional relation.And gas-liquid reaction needs mass transfer, liquid internal is high collision, so although be less than gas-solid/liquid/gas reactions, but be greater than gas-solid reaction.Gas-solid reaction has mass transfer and reaction is confined to the surface of solids, so reaction speed is the slowest.
Based on this, all oxidants of this technology are all gaseous states, and therefore than absorption method, absorption process, bioanalysis etc., its reaction speed is not obviously at an order of magnitude.
First be blower fan power consumption, due to without mass transfer, so drag minimization.
Secondly need not add medicament, so operating cost is only the electricity charge.
Finally because reaction rate is high, so device volume is less, and cost is lower.
About selective problems:
Experiment shows, resonance quantum coordination technique seems to have special compatibility for " odoriphone ", and the reaction sequence of its reaction rate and ozone and pollutant seems and misfits.In theory, ozone should be according to the reaction that occurs in sequence of " olefine > amine > phenol > polycyclic aromatic hydrocarbons (PAH) > alcohol > aldehyde > alkane ", but in resonance quantum coordination technique, chemical reaction sequence is that the complexity being excited according to " functional group " is reacted.This may be because first ozone reaction can take the mode of electrophilic reaction, thus first react with " functional group one is odoriphone for example ", and seldom there is addition reaction with benzene etc.Have been found that the following fact: it is more effective that resonance quantum coordination technique is processed scent molecule, than process other waste gas for example benzene have speed faster.
