Description
Technical field
The utility model relates to the device eliminated and control the poisonous and hazardous superfine small particle in air.
Background technology
The impact of domestic because serious haze at present, it be the superfine small particle of representative is its main producing cause that people recognize with PM2.5, further investigation reveals that the particle comprising PM2.5 and more small PM0.5 diameter has huge harm to human body.
Member of Chinese Academy of Engineering Zhong Nanshan thinks: gray haze does not only have impact to respiratory system, also has impact to cardiovascular, the cerebrovascular, nervous system.Atmosphere pollution is much all more fearful than SARS, but anyone can not run away.This injury for a long time has started to display to have a lot of numeral to suffice to show that: Beijing over 10 years lung cancer add 60%, in the national malignant tumor death rate, lung cancer ranks the first, and expert claims haze weather more easily to cause lung cancer than smoking.Separately have research display, gray haze is from 25 micro-/m
3be increased to 200 micrograms/m
3time, average daily case fatality rate can be increased to 11%, does not say future, and these reality injuries of being close at hand, have pressed the bottom line of the basic living environment of the mankind hard.If such atmosphere pollution also must bear three ISUZU company, that necessarily a generation in pollution, gradually lose life, a generation wastes away in pollution, also have what future value must expect.The minimum patient of East China lung cancer only 8 years old, the reason that this 8 years old young girl suffers from lung cancer is lived on road limit, owing to sucking road dust for a long time, just causes the generation of cancer.Haze mainly because PM2.5 can be deposited on lung and cause inflammation, thus causes some malignant changes.According to expert introduction, the PM2.5 granule in haze, not only dust, also have flue dust, comprise the waste gas etc. of vehicle exhaust, industrial discharge, these materials all contain a lot of environmental pollution toxin, science is referred to as environmental pollution estrogen, can be absorbed invade human body by number of ways.
Therefore, the superfine small particle of elimination and control PM2.5-PM0.5 scope, the estrogen namely in environmental pollution has been the technology of the urgent needs of society and country.
Utility model content
For above-mentioned technical problem, the purpose of this utility model is the device providing a kind of elimination and control PM2.5-PM0.5 range of particle thing.
The device of a kind of elimination and control PM2.5-PM0.5 range of particle thing, it comprises shell, positive plate, minus plate, adjustable high-voltage electrostatic generator, positive plate and minus plate is provided with in shell, positive plate and minus plate are at least one group, transpostion interval is arranged, many a slices of quantity of the number ratio minus plate of positive plate; Be connected by positive plate connecting line between adjacent anode plate, be connected by minus plate connecting line between adjacent cathode plate, the electrostatic generator anode output end of adjustable high-voltage electrostatic generator is connected with positive plate connecting line, and electrostatic generator cathode end is connected with minus plate connecting line; Positive plate is provided with pole plate sorbing material.
Research process of the present utility model is as follows:
One, to the analysis and research of PM2.5 particle:
The antinomy of 1.1 General Physics screen packs:
Present known PM2.5 refers to that in air, diameter is less than or equal to the superfine small particle of this class of 2.5 microns, the size carefully analyzing conversion 2.5 microns is exactly 25 nanometers, and PM0.5 only has 5 nanometers, if the mesh size of the particle utilizing " General Physics screen pack method " to filter out PM2.5-PM0.5 scope so screen pack must be less than 2.5-0.5 micron, the particle of these size diameter can be filtered out so in theory, but the screen pack that mesh is so little can not by air stream, an antinomy that Here it is, the mesh size of the screen pack that air can flow through is greater than 2.5-5 micron certainly, it is generally the size being slightly less than PM10, but be greater than the size of PM2.5 from far away, the filter screen of such size cannot filter out this kind of particle of PM2.5-PM0.5, these particles can pass through screen pack, if and air just cannot have passed when the mesh of screen pack is less than 2.5-5 micron, even if forced air forces air to flow through under stress, also the side namely can pressurizeed in the inside of very short time filtering net also can because of the run-up blocking of this kind of particle cisco unity malfunction, moreover use air pressurized to consume a large amount of energy and just blocked in the short time again, it is a passless road, so conclusion is: General Physics screen pack can not filter out PM2.5 more can not filter out PM0.5.Therefore every use screen pack (filter membrane) mode technology of eliminating PM2.5 is infeasible.
The characteristic of the superfine small particle of 1.2 nano level PM2.5-PM0.5 scopes:
We know that the size when solids is tiny of having many extremely special performance appearance different under normal conditions during nanoscale, make to which create small-size effect, quantum size effect, skin effect, macro quanta tunnel effect etc., thus make nano material show optical, electrical, thermal and magnetic, absorption, reflection, absorption, catalysis and the property such as physics, biologically active, examination is analyzed as follows:
1.2.1 hydrophobicity is inquired into:
When the size of the particle of PM2.5-PM0.5 is little of being also so same during nanoscale, the feature that we observe is exactly its " hydrophobicity " according to general general knowledge " spray water or water smoke can depositing dust ", this is a traditional general knowledge, in the particle of more than PM10, application is also successfully right-on, but the PM2.5-PM0.5 particle being applied in nano-scale but shows strong hydrophobicity, these particles can not be combined automatically with water and water smoke (containing water vapor), the superfine small particle of PM2.5 scope can not be reduced when fully showing spray water and water smoke (containing water vapor), what assumed as a matter of course in a lot of city carries out a large amount of road surface or sprays water in the air and water smoke, do not obtain the significant effect reducing PM2.5 fine particle thing, namely still conveniently thinking tackles the particle of PM2.5-PM0.5, hardly realize the performance not following routine at these tiny and superfine small particles nano level, but anti-convention.
In addition, when producing a large amount of water smoke in south or air, we see that PM2.5 and water smoke do not merge, it is the situation that a mist and haze (i.e. the particle of PM2.5 scope) exist jointly, it is again mist, when being again haze, haze degree is more serious, this phenomenon also illustrate that the characteristic of the particle of PM2.5 scope when nano-scale, namely have very strong " hydrophobicity ", exactly because this reason, disappear so can not be attached together automatically when mist and haze exist jointly or become larger particle automatic sedimentation to ground, this phenomenon illustrates whether use water spray and the steam-laden method of sprinkling water smoke to tackle this kind of superfine little particle effectively is also worth studying again, nano level particle not conveniently performance can solve, therefore " spraying " that use, namely spray water, the technology of spraying water smoke and steam elimination haze is also infeasible.
1.2.2 oil repellency is inquired into: use oily liquid and the particle of oil film to PM2.5 scope to adsorb, wish to utilize these particles of oily adhere objects to be equally also there is no effect strictly speaking, also show the characteristic of very strong " oil repellency " at the particle of nano level PM2.5 and PM0.5, the method for the particle eliminated and reduce PM2.5-PM0.5 scope is also impracticable therefore to use fluid body and oil film attachment technique to wish.
Two, the deficiency of traditional electrical dedusting technology and other electric treatment technology and disadvantage:
The particle effect that 2.1 traditional electrostatic precipitation technologies make again " high pressure electrostatic precipitation technology " to tackle more than PM10 is reasonable, the toxic emission of the smokestack of a lot of large enterprise now all have employed this high pressure electrostatic precipitation technology, but the particle of more than PM10 diameter can only be solved, or can not solve the particle problems of PM2.5-PM0.5, we think because following problem causes:
(1) pole plate in traditional electric precipitation, high-pressure static cleaner, positive plate and negative plate are all manufactured by all-metal material, there is no small and atomic little space, superfine little particle can not be adsorbed and be detained as the particle of PM2.5-PM0.5, therefore these particles can not be lived by Adsorption And Retention.
(2) traditional electric precipitation operating voltage is in " corona voltage scope " air and fine particle thing can be made to be ionized into ionic condition (being also called low temperature plasma) by this high voltage, oxygen in air can be excited and reconfigure, ozonize (someone is also called negative oxygen ion), and ozone is air-polluting very large pollution sources, Here it is inevitably creates again another two kinds of pollution sources when electric precipitation process fine particle thing, i.e. ozone and low temperature plasma, fine particle thing be activated into ionic condition (low temperature plasma) afterwards character great changes will take place, these low-temperature plasmas are poisonous and hazardous to human body.These low temperature plasmas are no longer adsorbed on negative plate according to the mode of imagination after producing, but can disorderly fly disorderly to hit between pole plate, greatly reduce the efficiency of dust collection of fine particle thing.The particle being simultaneously adsorbed on more than the PM10 on pole plate also can be cumulative, make that corona phenomenon is even more serious can produce ionization " snowslide " phenomenon when exceeding certain voltage value, namely a large amount of air is ionized to ozone instantaneously, a large amount of generation electron ion (low temperature plasma), increase the weight of the pollution of air on the contrary, because caused by the gap smaller of pole plate electric current under same corona voltage sharply becomes greatly, disruptive discharge phenomenon will be produced between pole plate, now just without any Electrostatic Absorption and dustproof function when reaching breakdown voltage.Therefore devise all in addition " beating unit " on the pole plate of traditional electrical cleaner, these sticked to the particle impact of pole plate, shake, the superfine small particle be temporarily adsorbed in this process in the middle of PM10 can fly upward again again, is again discharged in air.Therefore adopt traditional electrical dedusting or electrostatic precipitator technology, even wish that the particle being eliminated PM2.5-PM0.5 scope by the ionization mode of high-tension electricity is not all right.
2.2 electron ion technology, ultrasonic technology, laser technology analysis: these technology are all, at the atomic scale of air and particle, small electronics and atom effect occur, can make the character of superfine small particle that large change occurs, but although these superfine small particles change character, but or be that particle or even more tiny particle exist, itself is Adsorption And Retention not, be still exist aerial.
Three, technological core introduction of the present utility model:
3.1 basic structures are analyzed from physics aspect: the utility model is provided with one group of pole plate of more than two panels, use air circulation formula sorbing material absorption method but not the methods such as block type strainer filtering method and other such as water spray, oil glue, corona, ionization, ultrasonic wave, laser, distance between pole plate is minimum to be set to 1 millimeter (small-sized, microminiature), maximumly can be set to 200 millimeters (large-scale, ultra-large types).And air is unresisted in the least from these pole plates passing through, superfine small particle in the process passed through inside air is driven on absorption pole plate under the effect of DC high voltage electric field, undertaken adsorbing, being detained by the sorbing material on absorption pole plate, doing so avoids the antinomy of physical filtering net.
Distance between 3.2 every sheet pole plates can set arbitrarily, just regulate according near critical corona voltage after the setting of pole plate gap, the voltage of adjustable electrostatic generator is progressively raised, when there is corona phenomenon between two-plate, namely small hiss is had, just top out when can see have blue light to occur at dark place voltage, then by voltage live low adjustment some, more lower slightly than corona voltage, magnitude of voltage after adjustment is the scope of the 85-90% of corona voltage, corona phenomenon is disappeared, this voltage is exactly near critical corona voltage, pole plate is when this voltage range works, namely high voltage electric field can be kept the driving of superfine small particle, absorption, storage effect, can not air ionization be made and produce the ozone pollution of secondary and the contamination phenomenon of electron ion (low temp. electric gas ions) again.
Adjustable high-voltage electrostatic generator (D) adjusts the 85-90% that voltage is corona generation voltage.Be near critical corona voltage, the high voltage electric field between pole plate can be kept when this magnitude of voltage, and corona phenomenon neither occurs between pole plate also punch-through does not occur namely, the secondary pollution such as ozone and low temperature plasma can not be produced.
Operating voltage select close to and lower than in the scope of corona voltage, with closest to corona voltage and don't the pattern of high voltage electric field work that corona occurs, namely to eliminate and the superfine small particle that adsorbed PM2.5-PM0.5 scope turn avoid ozone and other electro-ionic generation.
The setting of 3.3 absorption pole plates and non-pole plate: generally adsorbing pole plate is by the minus plate made with Attapulgite Clay Minerals material, and then adsorption effect is better absorption can be made positive plate when moisture content is large.
The effect introduction of 3.4 absorption pole plates:
The making material of absorption pole plate is first-selected with the natural attapulgite originated from Gansu province (directions of Baiyin area and area, Linze), also the multiple material proposed in claims is comprised, this is because concave convex rod has natural powerful adsorptivity, its specific area is large especially, the micro-pore gross area of 1 gram of attapulgite material inside reaches 150-200 square metre, and most pore size is all be in nano-scale range, when being adsorbed on absorption pole plate under the driving effect at high-tension electricity field force of the superfine small particle of PM2.5-PM0.5 scope, superfine fine pore in the material of absorption pole plate just in time can allow these superfine little particles enter, after these superfine little particles enter into the hole of absorption pole plate would not more out namely storage be trapped in these sorbing materials, especially the particle of PM2.5-PM0.5 scope, be in nanoscale already, common water fog method, oil bonding, ionization method, corona method, laser method etc., all it is not acted on, say nothing of has been physical filtering method, only have higher do not produce the driving of the electric field force of corona under can be adsorbed, storage is detained in the sorbing material of absorption pole plate and no longer overflows, and the absorption pole plate that we are arranged has the material making of high specific area, namely there is nano level many holes, these superfine little particles will be captured by these holes and no longer out like this.
The introduction of attapulgite: attapulgite (Attapulgite) has another name called palygorskite or Palygorskite (Palygorskite), a kind of clay mineral that to refer to attapulgite (attapulgite) be key component.Attapulgite is under the jurisdiction of sepiolite group on mineralogy classification, is a kind of crystalloid hydrous magnesium aluminium silicate mineral.Be a kind of layer of chain structure containing Shuifu County's zeopan clay mineral.Its desirable molecular formula is: (Mg, Al, Fe) 5Si8O20 (HO) 2 (OH2) 4.4H2O, theoretical chemistry composition is: SiO
2account for 56.96%; (Mg, Al, Fe) O accounts for 23.83%; H
2o accounts for 19.21%, and attapulgite has the natural feature of environmental protection, is can as the harmless natural rare earth of one of food additives, drug additive.
3.5 except attapulgite material, natural non-metallic poromerics is as sepiolite, montmorillonite, diatomite, bentonite, kaolin, white afrodite, opal, dolomite, lime stone, magnesia, calcium carbonate, zeolite, gypsum, potter's clay and natural loess, laterite, these materials of black earth also have micro-pore, also the sorbing material directly making absorption pole plate can both be brought, but be all not so good as attapulgite material, especially in recyclability, all attapulgite material is not so good as, because attapulgite is a kind of edible natural environmental-protective material of human body that can be directly used in feed and field of medicaments, this is the maximum environmental-protecting performance of attapulgite, the main cause being preferably natural attapulgite mineral material is that this thing comes from natural minerals, price is extremely low, best performance, quality is best (the cleanest, harmless), namely cost minimum frequency is best), other material is all less than this material.
Sorbing material also comprises the nonmetal microcellular foam that kinds of artificial manufactures, there are artificial zeolite, cellular plastic foamed material, micropore air entrained concrete, micropore ceramics material and active carbon etc. can be used for making negative electrode adsorption plate, but all can carry out the utilization in later stage less than concave convex rod sorbing material, but also can be made into adsorption plate.
3.6 absorption pole plates can adsorb completely superfine small particle in work after certain hour makes adsorption effect be deteriorated, at this moment absorption pole plate must be changed, because the particle of absorption is superfine little, space in shared sorbing material is also little especially, so sorbing material absorption is chronic, even just absorption is full after half a year to reach some months, is therefore have good practicality.
The full pollutant of absorption attapulgite material can recycle to make fertilizer, as: the main component being designed to the attapulgite material absorption after adsorbing the discharge flue dust of coal burning plant and adsorption vehicle tail gas is through the hydronitrogen after high-temp combustion, the gas of hydrocarbon and particle, even if but the initial stage is gaseous state just become a kind of solid state being adsorbed onto inside attapulgite material, this is a kind of rich nitrogen, carbon rich material matter, (fermentable after the link of organic fertilizer, sterilization, sex change) be exactly the rich nitrogenous fertilizer material that can be utilized by plant, so attapulgite sorbing material can recycle after replacing, therefore the utility model is also containing the good environmental benefit that discarded object re-uses, final residue to be converted into the valuable fertilizer that is rich in nitrogen and residual without any residue, whole process is all environmental protections, sorbing material and recycling pattern are also unique.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In embodiment, adjustable high-voltage electrostatic generator is bought in Longquanyi District, Chengdu, Sichuan Province Xihe River town innovative electronic electrical apparatus factory.
The device of a kind of elimination and control PM2.5-PM0.5 range of particle thing, it comprises shell 1, positive plate 2, minus plate 3, adjustable high-voltage electrostatic generator D, positive plate 2 and minus plate 3 is provided with in shell 1, positive plate 2 and minus plate 3 are at least one group, transpostion interval is arranged, many a slices of quantity of the number ratio minus plate 3 of positive plate 2; Such as, when having the pole plate of sorbing material to be 10, the pole plate of non-adsorbed material is 11, and total tablet number is 21.Be connected by positive plate connecting line 4 between adjacent anode plate 2, be connected by minus plate connecting line 7 between adjacent cathode plate 3, the electrostatic generator anode output end 5 of adjustable high-voltage electrostatic generator D is connected with positive plate connecting line 4, and electrostatic generator cathode end 6 is connected with minus plate connecting line 7; Positive plate 2 is provided with pole plate sorbing material.
There is the pole plate of sorbing material can as minus plate, also can as positive plate, mainly determine according to the water content in air, when discharge as large factory is wet dedusting, in gas, moisture is large, at this moment can making positive plate by having the pole plate of sorbing material, minus plate can be made by having the pole plate of sorbing material when large-scale absorption car or other occasion.Sorbing material can be recycled after absorption is full, a kind of source as fertilizer can as the nitrogen element of fertilizer, be blended according to a certain percentage in organic fertilizer, apply farmland or planting use, reach the omnidistance environmental protection process without any residue.Be only periodic replacement absorption pole plate in long-term work, and non-adsorbed pole plate need not be changed, this also reduces the workload and consumption of materials of changing pole plate.
Pole plate sorbing material is natural non-metallic microporous mineral material or non-metal foam type poromerics.Natural non-metallic microporous mineral material is the one in attapulgite, sepiolite, montmorillonite, diatomite, bentonite, kaolin, white afrodite, opal, dolomite, lime stone, magnesia, calcium carbonate, zeolite, gypsum, potter's clay and natural loess, laterite, black soil.Non-metal foam type poromerics is selected from the one in artificial zeolite, cellular plastic foamed material, micropore air entrained concrete, active carbon or micropore ceramics material.
Positive plate 2 and minus plate 3 are square or rectangle.Absorption pole plate is straight tabular, then non-adsorbed electrode plate structure is the tabular and netted that stainless steel makes, be arranged parallel with dielectric support between two-plate, the class of insulation is according to the height different designs of polar plate interval and voltage, the larger class of insulation of polar plate interval is higher, and the nonparallelism error of two kinds of pole plates is within upper and lower 10%
The area of minus plate (pole plate of non-adsorbed material) is slightly larger than positive plate (having the pole plate of sorbing material) area.Such as the length of side of minus plate 3 is greater than 10% of the positive plate length of side, and when there being the every length of side of the pole plate of sorbing material to be 100 millimeters, the every length of side of pole plate of non-adsorbed material is 110 millimeters.
The pole plate group of smallest to be every length of side the be rectangle (2 centimetres wide, 4-10 centimeter length, is that small-sized, microminiature absorber uses) of 20 millimeters, often organizes pole plate installation interval and is of a size of 1-2 millimeter.
Largest pole plate group is that 8000 millimeters (8 meters square, are the adsorption box sizes of absorption coal burning plant discharge) are square, and the pole plate total tablet number of sorbing material is 41-91 scopes, can connect use with the large-scale electrostatic precipitator of coal burning plant.It is 21-61 sheet scopes that large-scale absorption car is generally designed to 2500 millimeters of (2.5 meters square) total tablet numbers.
Distance between positive plate 2 and minus plate 3 is 1-200 millimeter.
Adjustable high-voltage electrostatic generator (D) adjusts the 85-90% that voltage is corona generation voltage.Adjustment and the defining method of near critical corona field power (voltage) are: when fixed polar plate distance, as, during 2 millimeters of pole plate distances, regulate the voltage of high-magnitude DC electrostatic generator, corona phenomenon can occur when voltage is elevated to certain value between two-plate, when corona phenomenon occurs, the voltage of high-magnitude DC electrostatic generator is stopped to raise, back adjust the voltage of electrostatic generator when this magnitude of voltage, namely reduce voltage, till there is not corona phenomenon.
Near critical corona field intensity (voltage) refers to the magnitude of voltage not only maintaining high voltage electric field but also can not produce corona and ionization phenomena between pole plate.
Distance dependent between near critical corona field intensity (voltage) and pole plate, follows square relation be inversely proportional to of corona voltage and pole plate distance, namely distance nearer, corona phenomenon and breakdown voltage lower, with distance square in functional relation decline.As, when the distance between pole plate is 2 millimeters, near critical corona voltage is 3000V(± 10%), and when the distance between pole plate is 10 millimeters, near critical corona voltage is 30,000 V(± 10%).
The course of work: first assemble shell 1, positive plate 2, minus plate 3, adjustable high-voltage electrostatic generator D, positive plate 2 arranges pole plate sorbing material, pole plate sorbing material is that Gansu Province produces attapulgite.Allow air stream 8 access to plant not eliminating PM2.5-PM0.5, through the absorption of pole plate sorbing material, eliminate air stream 9 bleeder of PM2.5-0.5.
Illustrate: Fig. 1 is using positive plate as absorption pole plate, if the occasion being used in high humidity can using cathode plate as absorption pole plate, method is very simple, is only exchange by the input of adjustable high-voltage electrostatic generator and output, to adapt to different humidity environments.
Application examples 1-makes purifying vehicle exhaust car
According to principle of the present utility model, design one group of pole plate group and be arranged in van-type goods vehicle, shell is done with van, the air stream of input is sent into fan, after the driving of electric field force and the suction-operated of sorbing material, the cleaned air eliminating PM2.5-PM0.5 particle is got rid of with another group fan again, and Air Blast fan and air ejector fan can speed governing, the adjustment of air-flow is carried out, to obtain optimum efficiency according to the air pollution concentration of process.Namely this car becomes the special-purpose air purification automobile that can adsorb and eliminate the superfine small particle of PM2.5 and following scope in a large number, slow traveling is in the intensive location of wagon flow, nearby a large amount of tail gas of the motor vehicle emission of surrounding carried out adsorbing, eliminate, purify, reach and absorb auto-pollution tail gas, discharge the object of cleaned air thus significantly eliminate haze pollution sources.
Automobile exhaust pollution problem is global hard nut to crack always, extremely many utility model persons want originally to try every possible means with it at automobile, wish that the pollution of emission can reduce by automobile, hardly realize that automotive engineering has developed more than 120 year, through the effort of ten several generations, the efficiency of combustion of its engine has brought up to current 40%(gasoline car) and 50%(diesel vehicle), be the efficiency of combustion limit reaching internal combustion engine substantially, do not had large potentiality to have dug.And the quantity of nearly ten years automobiles adds nearly ten times, tail gas pollution is present quick growth state all the time, and it is insurmountable that thinking is traditionally made an issue of on automobile again.
And the present embodiment arranges large-scale absorption car around automobile, nearby, the pollution sources that automobile causes are fallen in absorption fast, according to the vehicle flow of automobile, arrange several or tens large-scale absorption cars to ferry and solve problem, fundamentally significantly can reduce automobile exhaust pollution, solve this world-class difficult problem by this mode.
Application examples 2-makes coal burning plant cleaning of emissions adsorption box
Undoubtedly, the discharging waste gas of current whole coal burning plants in use, although be up to state standards (from counting the national standard before being at present), all not reaching the state of the particle eliminating PM2.5 completely, saying nothing of the particle eliminating PM0.5.
According to the utility model principle, the adsorption box of large-scale PM2.5 particle can be designed, the smokestack being serially connected in discharge is anterior, now become absorption pole plate with regard to anode plate design, because a lot of factory has promoted and has employed wet dust removal pattern, in emission gases, humidity is very large, now using positive plate as absorption pole plate better effects if.
Although the discharge index of national standard, does not eliminate the consciousness in haze source before the gas of this kind of plant emissions reaches, the superfine small particle of a large amount of PM2.5-PM0.5 scope is also had again not adsorb, eliminate and then be discharged in air.In order to reduce costs, the shell of this large-scale adsorption box can adopt van container to make, because our technical pattern is simple, with low cost, adsorption plate material can also be collected the re-using of rich nitrogen material and make fertilizer, also being highly advantageous to agricultural so not only can save a lot of factory, is kill two birds with one stone.
