Description
[technical field]
The present invention relates to self power generation and article intellectualized technology field, specifically a kind of self power generation haze air filter.
[background technology]
Along with society's industrial expansion, bringing to people's life abundant, simultaneously easily, also result in many problems, environmental pollution is one of the most serious problem.Because the haze weather that many-sided reason such as environmental pollution is formed has had a strong impact on the life of people.In recent years, Chinese each big city haze weather showed increased.Just there are only in January, 2,013 4 haze processes to shroud 30 provinces (district, city) in the whole nation, within 26 days, are all haze weather in Beijing.Report that 500 cities of Largest In China reach the air quality standard of world health organisation recommendations only less than centesimal city.On January 4th, 2014, mitigation is done, the haze weather of health risk is included in natural the condition of a disaster in 2013 and circulated a notice of by Ministry of Civil Affairs first in country.
Haze weather is a kind of atmospheric pollution state, haze is the general statement to suspended particulate substance content overproofs various in air, mainly comprise sulfur dioxide, nitrogen oxides and pellet etc., wherein pellet, i.e. equivalent aerodynamic diameter is to increase the weight of the main composition that haze weather is polluted less than or equal to the contaminant particle of 2.5 microns, and the healthy harm to people is the biggest.The diameter contaminant particle less than or equal to 2.5 microns directly can enter bronchus, even pulmonary by respiratory system.So, what haze impact was maximum is exactly the respiratory system of people, and the disease caused is concentrated mainly in the sick kind such as respiratory tract disease, cerebrovascular disease, nasal cavity inflammation.Further, during haze weather, Inhalable Particulate abruptly increase causes air flow property poor, and noxious bacteria and virus are to slowing of around spreading, and in air, virus concentration increases, and the risk of pathophoresis is the highest.U.S. Environmental Protection Agency (EPA) issues " about air particle interdisciplinary science assessment report " for 2009 and points out, have enough scientific research results to demonstrate Fine Particles to adsorb and have carcinogen and genotoxicity mutagen matter in a large number, very important negative effect is brought to health, including improving mortality rate, making chronic disease aggravation, make respiratory system and cardiac system disease progression, change pulmonary function and structure, affect reproductive performance, change the immune structure etc. of human body.Haze weather especially affects the fertility of the mankind and the health of infant.
Although government has taken much count of haze problem and has set about administering, but " Rome is not build in one day ", thoroughly solve the process of a haze problem necessarily long-term complexity.In order to tackle haze weather, market occurs in that some haze masks and for indoor air purifier.Haze mask is simple and convenient, but uses and have limitation.Air purifier typically by air exhauster by air suction machine, by built-in strainer filtering air, it is possible to Chalk-dust filtering, abnormal flavour, toxic gas and kill part antibacterial, or actively discharge sterilization gas thus purify air.Although actively discharging sterilization gas to kill some pathogenic bacterias but can not effectively reduce pellet, and sterilization gas being likely to cause the discomfort of sensitive group.Drainage screen can pollute particulate matter with adsorption filtration, but drainage screen needs often to change, because when drainage screen damage ratio is more serious, drainage screen not only can not play the effect purifying air, on the contrary can contaminated air.Change drainage screen not only inconvenience and cost of idleness.Air purifier typically requires more preferable filtering function then to require, and the mesh of drainage screen is less; so causing air flowing not smooth, if using air exhauster to promote air flowing, not only noise is big; and it is big to consume energy, and takes care of the pence and certainly will aggravate than more serious energy crisis and environmental problem.Therefore, market needs a kind of simple and effective, haze device of low-carbon environment-friendly.
It addition, available regenerative resource has solar energy, the temperature difference, vibration and noise energy etc. in environment.Wherein, solar energy is relatively big in sun straight shot places energy density, is then difficult with when shady place and night；Temperature difference energy supply needs the bigger temperature difference, is difficult with in natural environment；And vibrating ubiquitous with noise, the wind of such as nature, rain etc. can cause vibration.At present, vibration energy regeneration technology is broadly divided into three types: (1) utilizes electromagnet transduction device that vibration mechanical energy is converted to the electromagnetic type of electric energy；(2) utilize electrostatic generator that vibration mechanical energy is converted to the electrostatic of electric energy；(3) vibration mechanical energy is converted to the piezoelectric type of electric energy by the piezoelectric effect utilizing piezoelectric.Piezoelectric system has higher energy density.And piezoelectric type prisoner's energy apparatus structure is simple, it is simple to system modular, integrated and miniaturization, conveniently it is applied to engineering practice.
Although it is that some microelectronic devices are powered that many scholar's research demonstrate energy accumulator based on piezoelectric can gather vibrational energy under natural environment, but it is used for the self energizing of real life device by few people.And the most most of haze air filter, existing needs often to change the problems such as drainage screen, noise be big and power consumption is big, does not more have spontaneous electrical function, neither easy, efficiently the most not low-carbon (LC), environmental protection.
