Description

Two fans formula fresh air purifier

Technical field

The invention belongs to purification of air and control field thereof, particularly a kind of fresh air purifier, for the purification for PM2.5.

Background technology

PM2.5 refers to that in air, diameter is less than or equal to the particle of 2.5 microns, also referred to as entering lung particle.Its diameter is less than 1/20 of the hairline thickness of people.In western countries, the air cleaning unit of more than 90%, for autopath, namely produces serious uncomfortable people to pollen, pet hair, smog, mould and dust.And the more demand of Chinese is the waste particulate material in filtered air, a lot of rejected particles especially PM2.5 is more much smaller than the particle such as pollen, dust diameter, therefore, may not be suitable in China at the good purifier of western countries' effect.PM2.5 the generating resource is divided into: natural source, comprises soil airborne dust, plant pollen, spore, bacterium; Artificial source, comprises the flue dust such as fire coal, combustion gas, fuel oil, motor vehicle exhaust emission, second-hand-cigarette, life dust.

" air purifier environmental certification rule " has been issued at man of CQC the United Nations indoor environment and environmental friendly indoor product quality supervision and inspection center, the index such as purifying property and degerming performance of clarifier is all made explicit provisions, can allow to use environmental certification mark by the product of inspection, be provided with basic performance threshold to air purifier.But the detection method listed in " rule ", only for the inspection that PM10 particle concentration carries out, not for the regulation of PM2.5.

The multiple filtration net that air purifier sold on the market uses, has certain clean-up effect to harmful substances such as particle, dust, germ, formaldehyde, also may have the catharsis of certain limit to PM2.5.Detection data according to the Indoor Environment Detection committee show, still do not have which kind of purified product " can lead to and kill " all harmful substances at present, can only promote to some extent improving in air quality, play auxiliary function, what air purifier was declared can remove the saying of PM2.5 in air is completely untenable.

PM2.5 particle diameter is little, is rich in a large amount of poisonous and harmful substances, and the time of staying is in an atmosphere grown, fed distance is far away, thus larger on the impact of health and atmosphere quality.Research shows, the less harm to health of particle is larger.Fine particle can waft to place far away, and therefore coverage is larger.Fine particle is larger to the harm of health, because diameter is less, the position entering respiratory tract is darker.The particle of 10 μm of diameters is deposited on the upper respiratory tract usually, the be deep into bronchiole of less than 2 μm and alveolar, so PM2.5 is also called " can enter lung particle ".After PM2.5 enters human body to alveolar, directly affect the ventilatory function of lung, make body easily be in anaerobic condition.

On July 31st, 2013; in the June, 2013 that Environment Protect in China portion issues and the first half of the year Jing-jin-ji region, the Yangtze River Delta, Pearl River Delta and the display of 74 urban air-quality situations; June; 74 urban air-qualities number of days that exceeds standard is 35.6%; Jing-jin-ji region air quality is still the poorest; the maximum annual average of the average exceeding standard rate of PM2.5 appears at Beijing, exceeds standard 2.8 times.The first half of the year Xingtai, Handan, Baoding, Tangshan, Jinan, Hengshui, Xi'an, Zhengzhou is relative with the air quality in Langfang poor.In the first half of the year, all cities of Jing-jin-ji region all do not reach PM2.5 average secondary standard.

On October 17th, 2013, subordinate's international cancer research institution of the World Health Organization issues report, points out atmosphere pollution first carcinogenic to the mankind, and regards it as general and main environmental carcinogen.

On November 12nd, 2013, associating China Meteorological Administration of the Chinese Academy of Social Sciences issues " climate change Green Book ", and report claims haze weather unhealthful, except well-known meeting makes respiratory system and cardiac system disease progression etc., also can affect fecundity.

The air pollution of China is more and more serious, and the health problem that bad air quality is brought also is day by day serious.Such as, the report that the World Bank issues shows, the premature death number caused by outdoor air pollution, average every day is 1000 people, has the people of 35 to 40 ten thousand to be faced with death every year.1997, the World Bank with regard to pre-in respect of 50,000 Chinese because air pollution and premature death, the report of this part finds, the air pollution of China makes the life-span of city dweller decrease 18 years.

HEPA filter screen is a kind of internationally recognized high-efficiency filtering material, and initial HEPA is applied to nuclear energy research protection, is widely used in the place that accurate laboratory, medicine production, atom research and operation etc. need high-cleanness, high.HEPA is interwoven by very tiny organic fiber, and comparatively strong to the isolating power of particulate, aperture is small, and adsorption capacity is large, and purification efficiency is high.The clean usefulness of filter of HEPA high efficiency particle screen is directly proportional to its surface area.The HEPA high efficiency particle screen of air purifier is multilayer folding, and after launching, area ratio increases about 14.5 times when folding, and it is very outstanding to filter clean usefulness.But the defect of HEPA filter screen is, easily assembles dust and cannot clean, thus easily affecting the effect of purification of air, need periodic replacement, later stage use cost is high.

Activated carbon pore structure is flourishing, and specific area very large (1500 ㎡/more than g), adsorption capacity is very strong.Active carbon is with raw materials such as coal, timber and shells, obtains through charing, activation and post processing.Because the surface area of carbon granule is very large, so fully can contact with the external world, be commonly used in water treatment and air purifying process.The shortcoming of active carbon is: can only temporarily adsorb certain pollutant, and time temperature, wind speed are elevated to a certain degree, the pollutant adsorbed just likely dissociates out, again enters breathing space and causes secondary pollution.So often filtering material will be changed, avoid absorption saturated.

Household Air Purifier on current market, technical standard mainly filtering type and the electrostatic precipitation class two kinds of employing, product structure is roughly divided into:

HEPA filter screen (PM2.5 particle purifying)+active carbon filter screen (odor smell absorption)+other (operating functions);

HEPA filter screen (PM2.5 particle purifying)+active carbon filter screen (odor smell absorption)+ion wind technology (deep purifying)+other (operating functions);

HEPA filter screen (PM2.5 particle purifying)+active carbon filter screen (odor smell absorption)+ultraviolet lamp (sterilizing)+photocatalyst filtering net (decomposing formaldehyde, benzene lamp organic matter)+ion wind technology (deep purifying)+other (operating functions);

Electrostatic precipitator technology (PM2.5 particle purifying)+active carbon filter screen (odor smell absorption)+ultraviolet lamp (sterilizing)+photocatalyst filtering net (noxious material such as decomposing formaldehyde)+ion wind technology (deep purifying)+other (operating functions).

But because technology restriction, it is large to there is filter element replacing frequency in existing air cleaning facility, power of fan is large, cost is high, there are other as static radiation, the possibility of the pollution that light radiation etc. are new, particularly for the air cleaning facility of function with new wind, because the pollution level of the new wind in outdoor is high, filter core needs frequent replacing, for meeting clean filter function, the design of its filter core is thick, cause windage large, and the demand of demand fulfillment Wind Volume circulation, so it is large to have power of fan, noise is large, cost is high, filter material cost is high, maintenance cost is high, air quantity regulates the problems such as inconvenience.

Summary of the invention

A kind of two fans formula fresh air purifier is provided, it is integrated with new wind and air return function, return air inlet can be distributed in not chummery, adopts at least two blower fans to carry out the circulation of new wind, return air respectively, significantly reduces size and the power requirement of single blower fan, because new wind is separated with air return function, new wind filter core, return air filter core design respectively, filter core with strong points, and filter core thickness reduces, replacement frequency reduces, and reduces complete machine cost.
