Description

A kind of window air purifier

Technical field

The present invention relates to air purification field, be specifically related to a kind of window air purifier.

Background technology

Haze weather is a kind of atmosphere pollution state, haze is the general statement to suspended particulate substance content overproof various in air, and especially PM2.5 (equivalent aerodynamic diameter is less than or equal to the particle of 2.5 microns) is considered to " arch-criminal " that cause haze weather.

Haze, also claims the particle such as dust, sulfuric acid, nitric acid, organic hydrocarbon compounds in gray haze (smog) air that air also can be made muddy.The horizontal visibility of object is called mist or mist (Mist) in this phenomenon of 1000-10000 rice.Formed mist time atmospheric humidity should be saturated (when existing if any a large amount of nuclei of condensation, relative humidity not necessarily reach 100% just may occur saturated).Due to the mist scattering of aqueous water or ice crystal composition light and wavelength relationship not quite, thus mist seems to be creamy white or Bluish white and grey.Sulfur dioxide, nitrogen oxide and pellet are the main compositions of haze.

The harm that haze produces human body is as follows:

(1) on the impact of respiratory system

The constituent of haze is very complicated, comprises hundreds of Atmospheric Chemistry particulate matter.The particulate that the mainly diameter be wherein harmful to health is less than 10 microns, as mineral grain thing, sea salt, sulfate, nitrate, Organic aerosol particle, fuel and automobile exhaust gas etc., it directly can enter and stick in human respiratory tract and alveolar.Especially submicron particle can be deposited in upper and lower respiratory tract and alveolar respectively, causes the illness such as acute rhinitis and acute bronchitis.For chronic respiratory disease patients such as bronchial astehma, chronic bronchitis, obstructive emphysema and COPDs, haze weather can make state of an illness acute attack or acute exacerbation.If be in this environment for a long time also can bring out lung cancer.

(2) on the impact of cardiovascular system

Haze sky is also very serious on the impact of human body cardiovascular and cerebrovascular disease, normal blood circulation can be hindered, cause cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, angina pectoris, miocardial infarction, heart failure etc. may be brought out, make chronic bronchitis occur cor pulmonale etc.

Mostly current air purifier, be moveable indoor air-purifier.Such as,

CN104121633A discloses a kind of air purifier, comprising: air inlet; Gas outlet; Filter, filtering is from the pollutant the air that air inlet enters; Fan, by the air guiding gas outlet after metre filter; Air path switch, in a first state, makes the air after filtering discharge along the first air path from fan to gas outlet from gas outlet; In the second condition, by the air inlet side of the air directed toward filter after filtration; Heater, by filter and air heat to make pollutant from filter desorption; And ultraviolet source, send ultraviolet light to irradiate air, make to decompose from the pollutant of filter desorption.

The air purifier of prior art, majority is moveable air purifier, go to be all by filter or being used for of adsorbing purifies air, but the organic contamination in air, nitrogen oxide or oxysulfide be not by filtering or Adsorption, even if there is a few to adopt the air purifier of chemical catalysis, the pollutants in air of occluded air at normal temperatures, can not be reduced to ppm level in the short time by it.

Meanwhile, in indoor, the particularly indoor of local-style dwelling houses, due to frequently carry out indoor and outdoor ventilation ventilate, therefore cause room air frequently by outdoor haze, containing various organic air pollute.Therefore how solving ventilation and room temperature chemical catalysis purifies air, is the large technical barrier that this area faces.

Summary of the invention

The object of the invention is to propose a kind of window air purifier, this air purifier can purify haze air, only at room temperature, just by the haze in air, organic pollution (aromatic pollution such as formaldehyde, methyl alcohol, benzene), sulfur and nitrogen oxides fast decoupled, can effectively can purify the air of the interior space.

For reaching this object, the present invention by the following technical solutions:
