Description
Technical field
The invention belongs to environmental protection technical field, relate to a kind of purification sealing room air, improve the negative ion air-cleaner of IAQ (indoor air quality).
Background technology
Develop rapidly along with socioeconomic, people's living standard is in continuous improve, people live and the room of office has carried out top grade decoration, the room lining has been put various modern furnitures, as life and office appliances such as refrigerator, TV and computer, air-conditioning, printer, photocopier, wear various knitting class high-grade clothings.These physical products are being brought to people outside the comfortable live and work convenience, also the place air of living and working to people brings serious pollution, produce some to the deleterious material of health, as volatile organic gas such as benzene class and formaldehyde, radon, ammonia, floating dust, smog, and other harmful gas.Simultaneously, people remain in the noxious bacteria of body surface and virus etc., the air quality that these are all indoor with grievous injury in flow process.At present, when people require high-level material life, the environment of working and live also there is higher requirement, promptly requires to keep the temperature and humidity of room air suitable, reduce the content of harmful pollutants again as much as possible, increase the material favourable health.These are that conventional homoiothermic, damping and ventilation installation institute can't realize, need to adopt the anion air purifying device to realize, improve the rely indoor environmental quality of live and work of people, the enhancement health.
Negative ion air-cleaner produces negative oxygen ion exactly, utilizes these negative oxygen ions to make floating dust in the air, antibacterial, virus etc. by charged (charged), quickens sedimentation and collects the instrument that purifies air.In addition, after negative oxygen ion enters human body, can cause a series of optimum reactions,, repair undermined human body etc. as the active cell vitality; Regulate the central nervous system, improve coronary flow; The prevention respiratory system disease; Improve endocrine and metabolism; Increase body immunity etc.Therefore, negative ion air-cleaner is considered to improve IAQ (indoor air quality), and the most effective device promotes health.
At present, existing air purifier on the market mainly contains two types, i.e. air purifier and electronic type negative ion air-cleaner.Air purifier generally all adopts the power supply of positive direct-current high voltage power supply, mainly be to be used for floating dust and smog in the clean room, but, because this air purifier in the course of the work, discharge a certain amount of cation,, in air, just have quite high cation concentration along with the increase of depurator working time, and cation exist make that human body feels exhausted, dizziness etc., be unfavorable for health.Conventional electronic type negative ion air-cleaner, be to adopt the power supply of negative dc high voltage power supply, effect is to purify air and produce the negative oxygen ion favourable to health, still since the negative high voltage power source power supply induce negative corona discharge, discharge the ozone of higher concentration, along with the increase of depurator working time, make and contain ozone with high concentration in the room air, ozone with high concentration is harmful to health, so, must adopt and reduce ozone generating method.Usually adopt two kinds of methods, a kind of is to reduce negative corona discharge intensity, and the least possible generation ozone will reduce the generation of anion like this, has reduced the negative ion concentration of room air.Another kind of way is to increase the device of eliminating ozone, will increase the cost of negative ion air-cleaner like this.
Summary of the invention
The purpose of this invention is to provide a kind of corona discharge heating electrode method, to solve the existing high problem of negative ion air-cleaner ozone discharge capacity, make negative ion air-cleaner be operated in high strength of discharge zone, produce the negative oxygen ion of high concentration, the generation of ozone can satisfy the IAQ (indoor air quality) standard, simultaneously, ultraviolet light that high corona discharge produces and adjusting ozone generating amount make the present invention have sterilization and germ-resistant function.

High-voltage discharging electrode of the present invention is to adopt thin resistance wire, is embedded on the framework.Low-field electrode can adopt board-like electrode, also can adopt the mesh electrode.When airflow direction and direction of an electric field designed on the contrary, low-field electrode adopted mesh electrodes, and mesh electrodes adopts slick heavy wire to make.When airflow direction and direction of an electric field vertical design, low-field electrode adopts the plate electrode structure, and board-like electrode is slick metallic plate.Low-field electrode is a ground connection.
Blower fan of the present invention is an axial flow blower, and casing adopts insulant to make.
Beneficial effect of the present invention and benefit are to adopt the sparking electrode heating technique to reduce the generation of negative corona discharge ozone, make negative ion air-cleaner be operated in high electric field region, and then the negative oxygen ion of generation high concentration, improved the efficient of negative ion air-cleaner, content with indoor negative oxygen ion, favourable to health, and ozone concentration is far below IAQ (indoor air quality) standard (0.16mg/m
3, GB/T 18883-2002).The ultraviolet light that strong negative corona discharge produces has sterilization and germ-resistant function.Simultaneously, can regulate the ozone output of negative ion air-cleaner, make it have sterilization and germ-resistant function.The present invention has simple in structure, and is easy to operate, safe and reliable, non-secondary pollution, low cost and other advantages.Can be widely used in crowded place (market, school, station, meeting room, dining room, hospital etc.), also can be used for office, family room, the air cleaning in the vehicles various places such as (passenger vehicle, car, aircraft, train, steamers).
