Description
Technical field
The utility model relates to a kind of waterfall type structure of utilizing and the PM2.5 fine particle is carried out to the device of adsorption removal, belongs to fine particle and administers technical field.
Background technology
At environmental science, according to the atmosphere pollution existence, it is divided into to aerosolized pollutant (particle) and gaseous contaminant.The composition of particle is very complicated, depends primarily on its source.Mainly contain two kinds of natural source and artificial sources, but harm larger be the latter.PM2.5 particle finger ring border air Air dynamics equivalent diameter is less than or equal to the particle of 2.5 μ m, also claims fine particle, and this value is higher, just represents that air pollution is more serious.Although fine particle is content component seldom in the earth atmosphere composition, it has important impact to air quality and visibility etc.The fine particle particle diameter is little, contains a large amount of poisonous and harmful substances and the time of staying in atmosphere is long, fed distance is far away, thereby larger on the impact of health and atmosphere quality.In addition, fine particle is larger to the harm of health, because diameter is less, the position that enters respiratory tract is darker.The particle of 10 μ m diameters is deposited on the upper respiratory tract usually, be deep into bronchiole and alveolar that 2 μ m are following.Fine particle enters human body after alveolar, directly affects the ventilatory function of lung, makes body easily be in anaerobic condition.
The removal method of existing PM2.5 fine particle mainly contains filtration method, water absorption method, plant absorption process and anion sedimentation.Filtration method is to utilize air-conditioning, humidifier, air freshener etc. to absorb the PM2.5 fine particle, though can obviously reduce the concentration of PM2.5, filter membrane need to clean or change.The water absorption method is to adopt the fog of the generations such as ultrasonic atomizer, indoor cascade, pond to absorb airborne hydrophily PM2.5, and shortcoming is to increase humidity, and hydrophobicity PM2.5 can not effectively remove.The plant absorption process is to utilize plant leaf blade to have larger surface area to absorb pernicious gas and absorption PM2.5, and advantage is to produce favourable gas, but absorption efficiency is low.The anion sedimentation adopts the small particle diameter anion in anion to catch floating micronic dust, makes its cohesion and precipitates, thereby make air cleaning, when concentration reaches 20000/cm
3the time, airborne floating dust can reduce more than 98%, and the floating dust diameter is less, more precipitated, so, in containing the air of high-concentration anion, the micronic dust below diameter 1 μ m, bacterium, virus etc. are almost nil.
Although the efficiency of dust collection of existing dust arrester can reach more than 99% of quality, but the capture rate to superfine particulate matter is extremely low, the words of in quantitative terms calculating, still have to account for the flying dust sum superfine particulate matter more than 90% and enter in atmosphere, and mostly can't reach the up-to-date environmental protection standard of China (≤50 mg/m3).
Chinese patent literature 2011101744180 discloses a kind of " removal method and the removal device of fine particle ", the method is to make fine particle enter in a plurality of parallel to each other and adjacent band electric channels charged with air-flow, positive charge and negative electrical charge on lotus respectively in two adjacent band electric channels, described respectively with electric channel in through charged fine particle the coalescence that bumps of the particle passage by a plurality of conducting two-phases adjacent band electric channel, then by a capturing device, trapped.Removal device comprises the ground connection pole plate that several are set parallel to each other, and all is densely covered with equably through hole on it; Several passages, be equipped with the discharge lines that several are arranged along the length direction of passage in described each passage, and the described two adjacent interior discharge lines of passage are connected with a negative output power supply with a positive output power supply respectively; One capturing device, it is located at the tail end rear of described passage.CN101869872A discloses a kind of " bipolar charge reinforced fine particle aggregation device ", electrode system is placed in the exhaust gases passes of boiler export, the minus plate of rectangle and positive plate interleaved parallel to each other is separated into exhaust gases passes the subchannel of a plurality of positive corona passages and negative corona passage, discharge electrode is barbed nail corona electrode with equilateral triangle the distribute front of the positive plate that is vertically welded in plane and the front of minus plate, can make like this in whole passage to have electric field very uniformly, guarantee particle, especially ultra-fine grain short time in this zone obtains fully charged, improve to greatest extent the coalescence effect, reduced energy consumption.CN102961928A discloses a kind of " controlling the exhaust dust device with bag of PM2.5 fine particle ", comprise the sack cleaner body, offer the air inlet that connects intake stack, the air outlet that connects wind pipe on described sack cleaner body, described sack cleaner body bottom is provided with ash bucket, described sack cleaner body interior is provided with filter bag, described filter bag is corresponding is provided with deashing device, and the surface of described filter bag is coated with the nano paint layer; The deashing pressure of described deashing device is less than 0.1MPa; Described air inlet place is provided with coagulation device.Above-mentioned technology is all by the electrocoagulation technology, to make fine particle aggregate into larger particles to remove again, complex structure, consume energy high.
Causing not good reason of conventional P M2.5 fine particle removal effect is the character of aerosol particle thing motion close to gas molecule itself, adopting the gas separations such as absorption, absorption is the effective ways of administering the Aerosol Pollution stationary source, the nano_scale particle that particle diameter is less is attracted to filling surface, the superfine fibre structured packing is a kind of filler commonly used, structured packing is a kind ofly by even geometric figure, to arrange, the filler of neatly piling up, particle is in the absorption deposition of filling surface.But current filling adsorption mode is that filler is deposited in together, sprays by absorption liquid, mode is more single, and adsorption effect is undesirable.
Summary of the invention
The deficiency that the utility model exists for existing PM2.5 fine particle removal technology, provide a kind of simple in structure, consume energy low, remove the effective multiple adsorption removal device of waterfall type PM2.5 fine particle.
