Description
Technical field
The utility model relates to gas depoisoning purification techniques field, is specifically related to a kind of plasma producing apparatus for air-conditioning internal machine.
Background technology
Begin to concentrate the haze air pollution of outburst to cause the numerous common people showing great attention to air quality since 2012 ends, various air purifier products have appearred on the market, the quality of normal domestic use is small size air cleaner preferably, and price is many 2,000 yuan of left and right, and is partially expensive.If significantly not increasing under the prerequisite of cost, air-cleaning function is integrated in air conditioner, be expected generally to solve the IAQ problem.Some Air-conditioning Enterprise have aimed at this chance, try to be the first and release the air-conditioning products with " purification " ability of air.These products are all declared to remove PM2.5, fresh air, and its air cleaning principle is mainly that coarse filtration adds electrostatic precipitation.Have certain effect at the beginning of use, still, only collect do not process, unsterilised, the long-term use just needs regularly clear screen pack and dust arrester, regular maintenance not only increases material cost, also increases maintenance cost, and, the user is used bring inconvenience.In case screen pack and dust arrester can not in time be cleared up maintenance, that piles up for a long time stains the purification function decline that thing not only can make screen pack and dust arrester, even loses purification function, and the pollutant of accumulation, particularly bacterium also can cause secondary pollution.Therefore, must carry out instant collection and treatment to pollutant, pollutant is decomposed, contamination-free is piled up, and keeps on the one hand the dust-free sterile of clarifier self, and is safe and reliable; Save on the other hand a large amount of maintenance costs and the expense of conversion materials more, improved its usage economy of clarifier.
In recent years, lower temperature plasma technology has the characteristics such as flow process is short, efficient is high, applied widely as a kind of emerging air purifying process, is widely used in the fields such as indoor air purification, industrial waste gas processing, dedusting and vehicle exhaust processing.Lower temperature plasma technology mainly is based on the atmospheric pressure plasma discharge technology, utilize large deep oxidation and the decomposition reaction that presses pollution sources in electric ozone, oxygen atom, the free group of hydroxyl isoreactivity and atmosphere or the water that produces, reach the purpose that removes harmful substance in atmosphere or water, follow simultaneously ultraviolet photolysis, shock wave, thereby remove organic matter, killing pathogenic bacteria in atmosphere or water.Namely utilize various living radicals and ultraviolet strong oxidation and sterilization effect in plasma, degraded organic contamination source, sedimentation metal ion, killing pathogenic bacteria, pollution sources to life and industrial discharge all have general applicability, volume compact, invest low, be not subjected to environmental limitations, be subject to extensive approval.
Plasma producing apparatus is integrated on air-conditioning internal machine, when regulating indoor air temperature by gas circulation, air-conditioning internal machine purifies air, at least saved the energy consumption of its motor operation than the air purifier of independent operating, and, the air-conditioning high temperature circulation has been utilized the diffusion principle of thermograde, gas circulation is more abundant, efficient is higher, and system is more energy-conservation.Air-conditioning has been the product of large-scale production on ripe streamline; also has a large amount of numerous common people storage air-conditioning just in use; can not return the streamline upgrading; if integrated plasma producing apparatus is too complicated; can significantly increase the upgrading cost of streamline, the upgrading of storage air-conditioning can't be carried out.Therefore, must on the basis of existing air-conditioning internal machine, carry out the simple air-cleaning function of transforming with regard to the integrated plasma producing apparatus of energy and get on, and significantly not increase cost, this just requires to take full advantage of the structure of air-conditioning internal machine, designs compact plasma producing apparatus.
