Abstract
The invention discloses a filter material for an air purifier. Firstly, activated carbon is treated by hydrochloric acid, then calcined in a muffle furnace, and finally dipped in a nano silver solution, and subjected to ultrasonic treatment. By adopting hydrochloric acid to treat coconut shell activated carbon, not only can the good strength and rich pores of the coconut shell activated carbon be retained, but also the surface functional groups of activated carbon can be adjusted, so as to improve the adsorption efficiency of activated carbon. At the same time, by the ultrasonic reaction, uniform distribution, stable attachment and no shedding of nano silver on the activated carbon is realized, and antibacterial effect is obvious.
Description
Technical field
The present invention relates to a kind of air purifier filtrate, belong to air purification field.
Background technology
Along with the fast development of China's economy, society, the continuous growth of the size of population, the quickening of industrialization and urbanization advances, and air pollution aggravates gradually, and the particle particularly existing in air has brought serious infringement to people's health.Particle, in environmental science, refers in particular to and is suspended in airborne solid particle or drop, is one of air-polluting main source.Wherein, aerodynamic diameter (hereinafter to be referred as diameter) is less than or equal to the particle of 10 microns and is called pellet (PM
10), diameter is less than or equal to the particle of 2.5 microns and is called fine particle (PM
2.5).Particle can stop for a long time in atmosphere, and can enter in body with breathing, accumulates in tracheae or lung, affects healthy.In the U.S., the death toll causing due to Particulate Pollution is every year about 22,000-52,000 people (2000 annual data), in this numeral of Europe up to 200,000.The researchers such as the Chen Zhu academician of the Chinese Academy of Sciences publish an article on " lancet " magazine, estimate that China causes because of outdoor air pollution every year morning dead person's number between 350,000-500,000 people.
People's nearly more than 80% time in all one's life is spent indoor, and therefore the quality of IAQ directly has influence on the healthy of people.Day by day serious along with outdoor air pollution, adds that the pollution of many interior decorations and ornament materials and a large amount of chemical article enter family daily life, makes that room air is same constantly to be worsened.And being widely used of air-conditioning makes indoor living space more and more be tending towards sealing, cause the self-detergent power of room air worse and worse.People have breathed stale room air, likely cause various respiratory tract disease.
Along with enhancing and the growth in the living standard of health of people consciousness, recognize all the more the importance of clean air to health.Therefore, air purifier enters into family and various office space just gradually.In European and American developed countries, air clearing product is generally for household, office life area.Survey data demonstration, air purifier reaches 27% in the popularity rate of the U.S., Japan 17%, Europe 42%, Korea S 70%, and China is less than 1%.
At present, the purification techniques that air purifier generally adopts both at home and abroad mainly contains: the methods such as UV purification, photocatalyst purification, plasma for purification, filtration, purification, electrostatic precipitation, adsorption cleaning, anion fine-purification, ozone purification, molecular complex.In these air purifying process, using absorption principle to purify air is a time-honored technology.Active carbon is the most frequently used adsorbent, and indoor multiple pernicious gas is had to certain suction-operated, but it exists, adsorbance is little, the easy shortcoming such as saturated, easy desorb, and limited to indoor major pollutants formaldehyde absorbing effect, and can not sterilization.
Summary of the invention
The present invention is directed to above-mentioned deficiency, a kind of air purifier filtrate is provided.
The present invention is achieved by following technical proposals: select 80-100 object cocoanut active charcoal, in the hydrochloric acid of mass fraction 10%, process 10-24h, clean by deionized water, then in the Muffle furnace of temperature 300-400 DEG C, calcine 1-10h.Then be immersed in concentration 0.001mol/L-0.1mol/L nano-silver water solution 60～80 DEG C of ultrasonic 1-24h.Wherein the synthetic method of Nano Silver is referring to Chinese patent CN200810122606.7, and the particle diameter of Nano Silver is at 5-100nm.
Compared with prior art, advantage of the present invention is:
(1) adopt hydrochloric Acid Modification cocoanut active charcoal, both retained intensity that cocoanut active charcoal is good and flourishing pore structure, by hydrochloric acid, the surface functional group of active carbon is regulated again, can improve the adsorption efficiency of active carbon.
(2) ultrasonic reaction makes Nano Silver on active carbon, be evenly distributed, adhere to stable, difficult drop-off, and antibacterial effect is remarkable.
(3) adopt the method for Chinese patent CN200810122606.7 to prepare Nano Silver, Nano Silver finishing one deck Hyperbranched Polymer with Terminal Amido, can promote cocoanut active charcoal absorption Nano Silver.Because abundant amino, imino group are contained in Hyperbranched Polymer with Terminal Amido surface, can play synergetic antibacterial effect simultaneously.
