Description
Technical field
The present invention relates to a kind of half wet cottrell, belongs to electric precipitation, waste gas pollution control and treatment and environmental protection technical field.
Background technology
With China's rapid development of economy, China big and medium-sized cities, developed area and basic industries close quarters
Gray haze air pollution is day by day serious.As China is for SOx and the restriction of NOx emission strict, related green technology and dress increasingly
Put and constantly come into operation, the gross contamination emission amplification of SOx and NOx slows down in China's atmospheric environment, however, from current prison
Survey result to see, the gray haze pollution of each section of China's Yangtze River Delta, Pearl River Delta and Jing-jin-ji region is on the rise on the contrary, is seriously threatened
The healthy and economic sustainable development of the common people.With tracing to the source the going deep into of research currently for gray haze pollution, Ren Menyi
It has been observed that PM10 granules share day by day reduces in China Brownish haze, PM2.5 even PM1.0 granules are greatly increased, these
Granule comes from VOCs, NOx and SO mostly2Multiple discharge coupling, its extinction capability is strong, toxicity is big, has become me
State's air environmental pollution problem the most serious.
It is related to numerous pollution industries due to administering industrial gases discharge, its difficulty of governance is very big, therefore many experts
Think, the change of atmospheric air quality needs just see within 10 years improvement at least, therefore, the purification to room air becomes at present
The most effective and most direct means of protection Chinese health of human body.
For indoor air purification except haze scheme is typically chosen HEPA filter membranes, this is a kind of very efficient air mistake
Filter material material, it might even be possible to remove the subparticle of below PM1.0, is current most ripe also most widely used purification of air side
Method, however, the shortcoming of this method is also it will be apparent that the air drag of HEPA films is very big, therefore it is enough in order to obtain
Air quantity, HEPA are generally required and are equipped with larger blower fan, this results in bigger power consumption and noise；Additionally, HEPA is effectively being filtered
After dust granules, the antibacterial for being attached to dust granules surface in a large number also can be in HEPA surface colonizations, therefore HEPA must be periodically
Change, the region serious for air pollution, the life-span of HEPA are very short, and this all brings higher cost.
The technology that indoor air purification is carried out using the scheme of electric precipitation also has certain application, and the technical scheme imitates work
The device of industry electric precipitation：First granule in air-flow is carried out using corona discharge electrode charged, electrically contrary dust collector pole is recycled to granule
Caught.The method is due to no any filtration material, therefore vapour lock is very low, it is easy to realize the air-treatment of Wind Volume,
But its shortcoming is also apparent：First, in this method, corona discharge electrode has the possibility for producing ozone secondary pollution；Second, single area
Electric field has been proved to very poorly efficient for PM2.5 and following granule；3rd, multi-region electric field is proved to for sticky particles (such as
Smoke from cigarette) there is certain effect, but for dry subparticle effect on driving birds is not good, main cause is subparticle load electric charge
Amount is few, and easily loses electric charge and leave dedusting pole, therefore the single technical scheme using common electric precipitation is difficult to room
In interior air, subparticle is sufficiently cleaned up.
Wet-esp is to be developing progressively a ripe novel dust removing technology on the basis of dry electric precipitation, the technology with
It is the moisture film for forming a laminar flow by the method for overflow or spraying in dust collecting electrode plate face where dry electric precipitation difference, appoints
What reaches the granule on dust collector pole surface because of electrostatic force all can be caught by moisture film, in this way greatly improve electricity and remove
Dust collecting method is for the seizure effect of subparticle.Yet with high-pressure electrostatic is equally used, so between corona discharge electrode and dust collector pole
Must be spaced sufficiently large, both arrangement is also particular about very much, with the accident for avoiding electrical breakdown.Therefore this technical scheme exists
Application is not still obtained to equipment volume and the extreme harsh domestic air purification field of security requirement.
It is also a kind of technical scheme for having put into application that the granule in room air is removed using the method for washing, the program
It is to blow air over larger wetted surface, by particle adhesion therein on a solid surface, then the method general by washing
Grain is removed.This scheme has certain effect for larger dust granule, fiber and pollen, but in current China's air
PM2.5 even particles below is then very poorly efficient, because these subparticles are very good with air flow property, using inertial separation
Method can hardly be removed.
Spraying washing is also the alternative for removing subparticle in room air, and the program is that water is sprayed mist with nozzle
Change, the little droplet of atomization to and particulate matter therein is caught during air contact, finally by demisting by air
Grain thing is removed.Rainfall in the much like natural atmosphere of this method disappears the process of haze, but its shortcoming is also clearly：First, it is this
Method needs to use nozzle, needs the liquid or gas of certain pressure, and this can bring extra equipment investment, also bring certain
Noise；Second, this method can cause the problem of room air " excessively humidifying ", can make one to feel not in humidity higher rainy season
It is suitable；3rd, the washings for spraying are often common tap water, for the water more containing mineral, meeting of spraying
Water evaporates are forced, is caused water mineral to be changed into the dust granules in air, is increased indoor accelerated test concentration.
The present inventor is it has been suggested that remove in air by the use of bottom rotary turnplate submerged in water as dust collecting electrode
The technical scheme (CN201410104461.3) of subparticle, the technical scheme are made using the moisture film of rotating disc surfaces
For the medium that gathers dust, dried dust and sticky dust can be effectively fixed, granule easily loses electricity in solving common electric cleaner
Lotus and the problem escaped, but the technical scheme also has its obvious defect：Each turn in technical scheme CN201410104461.3
Disk is same potential, can only catch load this granule with dust collecting electrode opposite charges, however, when dust granules are very tiny
When, its charging mechanism will be leading from electric-field charge for the leading diffusional charging that is changed into, and the effect of diffusional charging does not have significantly
Electric charge selectivity, therefore whether positive corona or negative corona, dust granules will be by load positive electricity and negative electricity simultaneously, and this causes
Dust granules removal effect of the technical scheme disclosed in CN201410104461.3 for less than 1.5 microns is less than 80%.
Make a general survey of all these technologies, China's room air is except haze field urgently a kind of low vapour lock, high flux, low noise, no
The high-effective dust-removing technical scheme of component need to be changed.
The content of the invention
It is an object of the invention to obtained by a kind of simple method fill with low vapour lock, high-throughout high-effective dust-removing
Put.The device possesses the advantage of wet static dedusting, at the same it is simple, liquid dispensing apparatus will not be introduced, is appointed without changing
