Description
Technical field
The present invention relates to a kind of plasma indoor air-purification device of vertical orifice plate bubbling humidifying.
Background technology
People's the time that surpasses half is in life at least spent indoor, because the interior space is effective, less with outdoor space exchange, indoor environment itself does not only have natural purifying ability, and owing to indoor dress is drilled, what air-conditioner etc. used popularizes and daily life, constantly discharging polluter to the interior space, it wherein mainly is volatile organic matter, harmful substance such as solid suspended particles and aerosol, formaldehyde for example, toluene, dimethylbenzene, benzene, amine, ammonia or the like, cause room air pollution, the serious harm people's is healthy, wherein main pollutant comprises formaldehyde and benzene series thing, therefore along with the raising of people's living standard and the aggravation of air pollution degree, the room air pollution problem more and more gets more and more people's extensive concerning.
In order to improve the air in the above-mentioned environment, people have adopted thousand and one way to kill airborne bacterium and have eliminated nuisance to reduce the pollution of air, the main at present method that adopts has: (1) air filtering method, by blower fan, just imitate, the middle effect, efficient composition such as (inferior efficient) filter, filtrate mainly is a glass fibre, synthetic fibers, asbestos fibre and filter paper or the filter cloth made by these fibers, so that airborne dirt ash is filtered to purify air, but these porous filter materials can increase the resistance that air flows, and along with the prolongation of service time, the effect of its filtration can descend, change as untimely, can add the pollution of heavy air on the contrary, even produce secondary pollution; (2) Cottrell process by circulating air is discharged, makes airborne dirt ash charged, utilize dust collect plant to capture charged dirt ash then, reach the purpose that purifies air, but this method can not be killed airborne bacterium, and be provided with and use inconvenience; (3) ultraviolet sterilizing method utilizes ultraviolet ray to kill airborne germ, but powerless to airborne dirt ash, can not purify air, and also be difficult to be arranged in the central air conditioner system use; (4) plasma purification method, highfield and gas discharge by the plasma generator generation, make airborne hydrone and gas molecular ionization, through exciting of a series of complexity, disassociation and ionization process, produce the extremely active .OH of chemical property, .H, .O wait free radical, the redox reaction of a series of complexity takes place with airborne pollutant, wherein the volatile organic matter molecule is decomposed, realize the purpose of air cleaning thus, these radical pairs also have strong deactivation in microorganism, when eliminating organic contamination, realized the purpose of sterilization, but the structure of existing plasma generator or plasma purification device is more complicated all, and the density of the plasma that produces is little, and air cleaning speed is slow, and the sterilization purification effect is undesirable.
In addition, existing indoor air cleaner is often only for airborne pollutant in the decontamination chamber, and because the restriction of indoor environmental condition, room air is often too dry in the most of the time, particularly for the northern area in heating season, for a long time drying not only makes the people not feel well, but also has brought increasing of suspended particulate substance and germ virus in the air, has influenced people's quality of life and health.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of plasma indoor air-purification device of vertical orifice plate bubbling humidifying, the structure of this purifier is simple relatively, ionization is effective, the plasma density that forms is big, higher clean-up effect can be realized, and the humidity of room air can be regulated.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of plasma indoor air-purification device of vertical orifice plate bubbling humidifying, comprise housing, be divided into bubbling humid cabinet and plasma for purification chamber in the described housing from bottom to top successively, described bubbling humid cabinet bottom is a tank, be provided with the orifice plate that is positioned at below the waterline in the tank, indoor earthing pole and the discharge electrode of being provided with of described plasma for purification, described earthing pole is tubular, connect power supply ground, described discharge electrode is shaft-like, the surface is evenly distributed with some discharge thorns, connects the output of high frequency electric source, and described earthing pole and discharge electrode are installed together by insulating support, the top of described housing is provided with air outlet, the side is provided with vertical blast pipe, and the lower end of described vertical blast pipe is communicated with described tank, and connection place is positioned at the below of described orifice plate.
Because the present invention is tubular with the earthing pole setting, and discharge electrode is installed on the axis of this tubular earthing pole, guaranteed the uniformity of electric field, guaranteed that whole ionization space all can produce good ionization, be not prone to the phenomenon of destroying whole discharge because of partial breakdown, the space in this tubular earthing pole has constituted the gas channel of plasma for purification chamber; Owing on discharge electrode, be provided with equally distributed discharge thorn, help near the discharge thorn, to form highfield, so that with ionization such as airborne hydrones, under lower voltage, just form good ionization, to avoid insulating, preventing creepage and, helping the simplified apparatus structure because of the too high generation of voltage request to many-sided harsh requirements such as air parameters; Because the discharge thorn is evenly distributed on the discharge electrode, helps everywhere discharge and ionization, forms higher plasma density,, improve clean-up effect to accelerate purification speed; Owing to below the plasma for purification chamber, be provided with the bubbling humid cabinet, airborne pollutant levels have been reduced, improved airborne water content, help to improve the indoor ionization property of plasma for purification, improve plasma density, reduce the pollutant burden amount of plasma for purification, improve degree of purification; Air is downward from blast pipe thus, enter tank from the bottom of tank, when by orifice plate, break through the water surface of orifice plate top, form a large amount of bubbles, in the collision process with water, materials such as airborne solid particulate matter and aerosol are entered in the water by water-wet, the solubility organic molecule is dissolved in the water, the part hydrone enters in the air simultaneously, forms airborne aqueous vapor, has realized the humidification and the preliminary purification of air thus; Because the impact resistance of this washing, purifying mode is more intense, under the situation that the pollutant levels variation occurs, still airborne level of pollution can be controlled within certain scope, guaranteed the reliability of this cleaning equipment thus, improved adaptability; Because this humidification mode enters airborne aqueous vapor when air is dry many, it is few to enter airborne aqueous vapor when with the humid air, even no longer in air, spread aqueous vapor (dynamic equilibrium), realized automatic adjusting thus, can not go out the phenomenon of the existing the sort of excessive humidification of air humidifier of phenomenon air humidity.
