Abstract
The invention relates to an indoor plasma dust particle purifier, which mainly adopts three technologies of ozone-free technology, mute technology and wide-spectrum alternating electric field generator. According to the ozone-free technology, the generation of plasma is controlled at the front section of effluvium and Townsend discharge, and the ion energy discharged in the section is extremely lower than required energy for producing ozone, so that no ozone can be produced. Fan-free air self circulation technology adopts fan-free and ion convective circulation technology, and the structure of a plasma space is designed according to aerodynamics principle, so that the flowing of plasma has different velocity layers, and a tangential pressure is generated through velocity gradient according to Bernoulli's theorem that the pressure generated by a fluid to matters around is inversely proportional to relative velocity of the fluid; and therefore, clean air flows outside an instrument, no fan is used, and the mute and energy-saving effects are achieved. The indoor plasma dust particle purifier has the beneficial effects that PM2.5 dust particles can be effectively collected so that the indoor concentration is decreased to accord with the national standard.
Description
Technical field
The invention belongs to the energy-conserving and environment-protective electronic technology field, relate to a kind of small household appliances that can remove indoor PM2.5, be specifically related to a kind of plasma micronic dust indoor air-purifier.
Background technology
The compound air pollution of current China comes back gradually, attaches most importance to the air particles pollutant especially, and wherein PM2.5 has caused concern widely especially.PM2.5 refers to that diameter is less than or equal to 2.5 microns particle in the atmosphere, also claims to go into the lung particle, and is very harmful to human body.The PM2.5 pollution problem of ground groups of cities such as China Beijing-Tianjin Ji, the Yangtze River Delta, Pearl River Delta is comparatively outstanding, country's relevant policies also require to strengthen the PM2.5 prevention and cure of pollution in above-mentioned area, increased the PM2.5 concentration value in the national standard newly, list the ambient air quality evaluation in, implement in China, this also is that China formulates the PM2.5 standard first.
A lot of indoor air cleaner products are arranged both at home and abroad, but belong to filter net type, effective to dust, PM2.5 is invalid to micronic dust, and Shang Weijian adopts the report of this project technology path product.The product that utilizes the ozone generator principle to purify air is quite a few, because harmful, the Ministry of Public Health prohibites popularization, and this project is series products comparison therewith not.
Summary of the invention
The invention solves the technical barrier that indoor PM2.5 pollutant exceeds standard.
The present invention adopts following technical scheme: the main technology that adopts has three: ozone free technology, quietness technology, wide spectrum alternating electric field generator.
Basic principle of the present invention is by non-self-maintained discharge, causes the ion convection current, adsorbs a large amount of PM2.5 micronic dusts, at the attached plate precipitation of collection caking, reaches the dedusting purpose, because suction-operated occurs in ion footpath degree, so more effective to more little micronic dust.
The ozone free technology is to control plasma generation in the leading portion of voltolising and townsend discharge, the energy that the ion energy of this section discharge needs far below generation ozone, so ozone free can produce.
No fan air self-circulation technology, adopt no fan, ion convection current circulating technology, according to aerodynamic principle, the structure of design plasma space, what make plasma mobilely exists different velocity layers, according to handkerchief slave Li Dingli " fluid to around the pressure that produces of material and the relative velocity of fluid be inversely proportional to ", velocity gradient has produced tangential pressure, make clean air flow to the instrument outside, without fan, reach noiseless and energy-saving effect.
The invention has the beneficial effects as follows: the attached PM2.5 micronic dust of energy active set makes indoor concentration descend to causing and meets national standard.The one, ozone free takes place, and is harmless; The 2nd, energy-conservation; The 3rd, the life-span is long, continuously operation; The 4th, full machine does not need the parts that regularly replace, only needs regularly to clean, because PM2.5 has been out of shape polymerization through chelating, flushing can not have new influence to environment.
Description of drawings:Embodiment illustrated in fig. 1, be micronic dust clarifier structural representation in the plasma chamber.
The 1st, collect attached plate, the 2nd, collect attached plate, the 3rd, collect attached plate, the 4th, emitter stage and cleaning ring, the 5th, emitter stage and cleaning ring, 6 wide spectrum alternating electric field generators, the 7th, electronic control system.
The specific embodiment:
1, wide spectrum alternating electric field generator (6) can produce the alternating electric field of 4-12Mhz, 30000V, and output current is not more than 20 μ a, and electric current and voltage control is with can the ionization micronic dust, and not producing ozone is purpose.
2, emitter stage and cleaning ring (4), (5), emitter stage is a wire, with ring-type dedusting ring; Cleaning ring is common annulus, ceramic material, and when ion emitters had micronic dust to pile up, micronic dust was removed in the removing of can manually overturning;
3, collect attached plate (1), (2), (3), be that stainless steel or aluminium alloy are stamped to form, the shape design is purpose can form the air channel, can make ion have different velocity layers, produce radial pressure thus, reach noiseless air circulation, collect attached strip static, make the micronic dust after the polymerization, produce electrophoresis, reach the purpose of collecting micronic dust, collect between the attached plate and isolate with separator, separator approaches zero plastic material by dielectric coefficient and forms.
4, electronic control part: present embodiment can be controlled power supply by electronic control system, divide retaining and cleaning.
5, technical indicator:
For the interior space of 60--90 cubic meter, start shooting and can remove PM2.5 fully substantially in 2 hours, to endangering maximum 0.6nm micronic dust, effect is particularly evident.
The present embodiment product detects in Environmental Science and Engineering system of Fudan University process in December, 2012:
Detecting instrument is that 3936 type lists of U.S. TSL company disperse particle diameter spectrometer/SMPS, the aerosol particle diameter scope 20-1000nm of detection.Another detecting instrument is 3321 type aerosol particle diameter spectrometer/APS of U.S. TSL company, the aerosol particle diameter scope 500nm-20 μ m of detection.
Testing conditions is, in the volume that door and window is closed was 60 cubic metres room, continuous detecting was more than 24 hours, and PM2.5 change in concentration during this period in the observation room is checked and inspected instrument by ready samples to the removing effect of PM2.5.
Detect conclusion: through the many days testing results of SMPS and APS, it is obvious that the PM2.5 of censorship product removes effect, can be used for the removing of interior space PM2.5.
