Abstract

The device pertains to air purification technology field, which comprises a shell; the external of the shell is provided with a handle, a switch, a plasma timing meter and power jacks; an air inlet and an air outlet are arranged on the shell; the internal of the shell between the air inlet and outlet are provided with a blower, a nano photocatalyst chamber and a radiation plasma chamber in sequence; the indoor polluted air under the drive of the air inlet blower, firstly, enters the nano photocatalyst chamber to carry out photochemical reaction to convert the pollutants into carbon dioxide and water, thereby realizing the function of decontamination. The purified air is blew into the radiation plasma chamber, enabling air to be further purified, and the purified air together with the high concentration plasma are blew out of the shell mixing with indoor air; the plasma actively contacts pollutants of indoor air and breaks the molecular chain of the pollutants, so as to eliminate the pollutants of the indoor air. The process can be continuously repeated to comprehensively purify indoor air.

Description

A kind of indoor air pollution fast control equipment

Technical field:

The present invention relates to the air purifying process field, the quick controlling device of particularly a kind of air pollution.

Background technology:

Along with scientific and technological progress and expanding economy, the air quality that the mankind depend on for existence constantly descends, and especially the pollution situation of room air constantly worsens, the indoor pollution that finishing, furniture etc. bring more and more widely, healthy to people of serious threat.Room air pollution is mainly organic chemical pollutant and microorgranic contaminant, these pollutant through science confirm be the various modern disease pathogenic because of, as leukemia, cancer, respiratory tract infection, nervous system disease etc.Therefore, how to carry out pollution cleanup fast at the indoor environment of having polluted, the human settlement who creates sanitation and hygiene is related to healthy even important thing life security the people of office work and life for a long time.

At present, people adopt different technology to develop various air purifiers.According to the difference of technology, it is several that indoor air cleaner mainly contains filtering type, adsorption-type, oxidation-type etc.Filter and the adsorption cleaning device mainly adsorbs filter course and the charcoal of room air by depurator inside to reach the purpose that purifies air by taking a breath, because the complexity of indoor environment makes ventilation abundant inadequately, the easily long-pending full dust of filter course descends thereby the saturated detergent power that makes easily takes place in charcoal absorption; And adopt the oxidation-type purification style of discharge generation ozone very easily airborne nitrogen generation ionization to be formed secondary pollutions such as nitrogen oxide.So the actual clean-up effect of the depurator of existing market is generally undesirable, in addition, at taking place such as fire, floods, finishing etc. under the situation of serious indoor pollution, still do not have to administer fast the short time, thorough decomposing pollutant and reach and remove the special purification device that pollutes purpose.

Summary of the invention:

The object of the present invention is to provide a kind of indoor air pollution fast control equipment, with the short time administer fast, thorough decomposing pollutant and reach and remove the purpose of polluting.

The foregoing invention purpose can be achieved through the following technical solutions:

This device comprises a housing, described hull outside is provided with handle, switch, plasma timing ga(u)ge and outlet, described housing is provided with air inlet and air outlet, be disposed with blower fan, nano photo-catalytic chamber, radiation plasma cavity in the described housing between described air inlet and air outlet, in described nano photo-catalytic chamber, be provided with ultraviolet lamp tube, at indoor power supply plug-in unit and the plasma generator tube of being provided with of described radiation plasma chamber.The inner surface of nano photo-catalytic chamber is cellular porous structure, and is coated with semiconductor catalyst.The pass of loose structure is any in triangle, square, polygon, circle or the Concha Arcae shape, and the material that constitutes cellular porous structure is any in aluminium, polymer, fiber, pottery, paper, the non-woven fabrics, or wherein several compound.The semiconductor catalyst that applies is: TiO ₂, ZnO, ZnS, Fe ₂O ₃, CdS, CdSe or WO ₃Particle, or be doped with any one or a few TiO among precious metal Pt, Pd, Au, Rh or the Ag ₂, ZnO, ZnS, Fe ₂O ₃, CdS, CdSe or WO ₃Particle, or by TiO ₂, ZnO, ZnS, Fe ₂O ₃, CdS, CdSe or WO ₃The composite semiconductor light-catalyst of compound composition between particle, or by TiO ₂, ZnO, ZnS, Fe ₂O ₃, CdS, CdSe or WO ₃In the particle any one or a few and ZnO ₂, HgS, PbS, AgI, SnO ₂, SiO ₂, ZrO ₂Or Al ₂O ₃In the composite semiconductor light-catalyst of any one or a few compound composition.The ultraviolet wavelength that ultraviolet lamp tube sends is between 100-420nm.The distance of ultraviolet lamp tube and nano photo-catalytic chamber inner surface is 10-100mm.The plasma generator tube is the U type or the H type is arranged in parallel.The plasma generator tube can be controlled separately.

Principle of the present invention is: the nano photo-catalytic semiconductor catalyst is under the irradiation of ultraviolet light, and the surface produces a large amount of hydroxyl radical free radicals, when contaminated air contacts with it photochemical reaction takes place promptly, and organic pollution is decomposed into carbon dioxide and water; Simultaneously, high power plasma generator tube irradiation air produces the plasma of high concentration, plasma also has strong oxidizing property, can the organic pollution that a lot of other ways are difficult to remove be decomposed, and initiatively fast organic pollutant is resolved into carbon dioxide and water.The combination of these two kinds of technology almost can all Organic substances of oxidation, comprise biological pollutants such as bacterial virus, until fully with pollution cleanup.

Device provided by the invention adopts high concentration plasma technology and nano photo-catalytic technology to be used in combination, can bring into play the strong point of two kinds of technology well, remove fast at indoor serious air pollution places such as finishing, fire, floods, epidemic situations, make IAQ (indoor air quality) reach human settlement's requirement in the short time.Because the inner surface of the nano photo-catalytic chamber of this device is alveolate texture, in appropriate distance, can fully be shone by ultraviolet lamp tube, thereby with reach maximization by the contact surface of air is long-pending.The plasma generator tube adopts parallel-connection structure.

Experiment showed, that the present technique device has the fast purification effect to the room air of severe contamination, comprises biological pollution and chemical contamination.
