Description
Technical field
The present invention relates to a kind of plasma and photocatalysis air purifying device of horizontal spray humidifying, belong to environmental technology field.
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 comprise 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 antibacterial 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 mobile resistance of air, and along with the prolongation of service time, its filtering effect 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 antibacterial, and be provided with and use inconvenience; (3) ultraviolet sterilizing method utilizes ultraviolet to kill airborne pathogenic bacteria, 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 pathogenic bacteria 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 and photocatalysis air purifying device of horizontal spray humidifying, the structure of this purifier is simple relatively, and good purification can be adapted to the purification and the damping of room air etc.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of plasma of horizontal spray humidifying and photocatalysis air purifying device, comprise housing, be divided into the spray humidifying chamber in the described housing from front to back successively, plasma for purification chamber and light catalytic purifying chamber, the indoor shower that is provided with the band plurality of nozzles of described spray humidifying, the bottom is a tank, described shower connects the immersible pump of described tank the inside, described plasma for purification is indoor to comprise the vertical flat board of a plurality of parallel and spaced sets, be evenly distributed with some discharging rods between described each flat board, have some equally distributed discharge thorns on the described discharging rod surface, described vertical flat board is connected with the negative pole of power supply, described discharging rod is connected with the positive pole of described power supply, described vertical flat board and described discharging rod are installed together by insulating support, the indoor photocatalysis uviol lamp that is provided with of described light-catalyzed reaction, described photocatalysis uviol lamp top and/or below are provided with several layers photocatalyst filter screen, the rear end of described housing is provided with air outlet, and the front portion is provided with air inlet.
Because the present invention has adopted vertical flat board and the discharging rod between parallel-plate to constitute discharging structure, by positive pole and the negative pole that inserts dc high-voltage respectively, both voltage output end and power supply ground, when voltage is enough big, on the gas channel that constitutes between the vertical parallel-plate, form ionic discharge, rely on high electric field with airborne hydrone and other molecular ionizations, the particle that forms the complexity that comprises plasma constitutes; Because each vertical flat board is parallel to each other and equidistantly, and discharging rod also is equally distributed, therefore the electric field that forms has good homogeneous, helps guaranteeing that whole ionization space all can produce good ionization, in order to avoid destroy the phenomenon of whole discharge because of partial breakdown; Owing on discharging rod, 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 discharging rod, helps everywhere discharge and ionization, forms higher plasma density,, improve clean-up effect to accelerate purification speed; Owing to be provided with the spray humidifying chamber in the front of plasma for purification chamber, both help reducing airborne pollutant levels, and helped again having improved airborne water content, improved the indoor ionization property of plasma for purification, improve plasma density, the humidity that can also regulate room air; Because the aqueous vapor that this humidification mode enters in the air flow when air drying is 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 existing the sort of excessive humidification phenomenon of air humidifier of phenomenon air humidity; Owing on the plasma for purification chamber, also be provided with photocatalysis uviol lamp and photocatalysis filter screen, by photochemical catalytic oxidation the volatile organic gas of remnants is further decomposed, air is further purified, help to improve detergent power, reduce equipment volume and cost.
