Description
Technical field
The present invention relates to a kind of air purification method and device.
Background technology
Along with increasing the weight of of national environmental pollution, air quality worse and worse, more and more pay attention to by the purification of air of people to living environment at one's side.But, existing air purification method can only dust in filtered air and particle, the filtering accuracy of filter core is relatively low, service life is shorter, and effectively can not remove the pernicious gas in air, such as nitrogen oxide, carbon monoxide, oxysulfide, formaldehyde etc.
In addition, existing air purification method is of a great variety, and function differs, but the structure of its air cleaning unit adopted is more complicated, and prevailing price is higher, is difficult to popularize.The filter core of current air cleaning unit mostly on the market is the material such as glass fibre, chemical fibre, and material cost is high, and mechanical strength is low, and the mode of washing can not be adopted to regenerate, and causes the renewal cost of filter core higher.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple and convenient, and regeneration easy to clean, filtering accuracy is high, effectively can remove air purification method and the device of the pernicious gas in air.
Air purification method of the present invention, its step comprises: air intake is in the air cleaning unit inner chamber of slight positive pressure state by a.; B., after the air entered in air cleaning unit inner chamber carries out gas solid separation filtration by filter assemblies, enter and be equipped with in the pure qi (oxygen) cavity configuration of adsorbent; C. removed the pernicious gas in pure qi (oxygen) cavity configuration by described adsorbent after, purified gas is discharged.In step a, air cleaning unit inner chamber is in slight positive pressure state, namely air cleaning unit inner chamber has the draught head a little more than external pressure, force the air in external environment, moisture, dust, salt fog etc. can not invading air purifier inner chamber, therefore the purification process of air cleaning unit inner chamber can not be affected, the efficiency of purification of air can greatly be improved thus.Make the working environment of the air cleaning unit inner chamber being in slight positive pressure state remain clean, drying regime, guarantee that the air quality after the purification of finally discharging from air cleaning unit is better.Carried out gas solid separation filtration by the air that air cleaning unit sucks by filter assemblies, the dust in removing air and particle, then enter in pure qi (oxygen) cavity configuration; Discharge removed the pernicious gas in air by the adsorbent in pure qi (oxygen) cavity configuration after.Described adsorbent is contained in pure qi (oxygen) cavity configuration, additionally can not increase the volume of air cleaning unit, reach the object making full use of space resources.According to different needs, can select to have the adsorbent of corresponding function targetedly and regularly replace, ensureing that clean-up effect is better.Learn after tested, gas solid separation is filtered and the separately process of absorption pernicious gas, relative to adopting the filter assemblies having absorption and filter double effects to carry out purification of air simultaneously, effectively can remove most dust, particle and pernicious gas in air, clean-up effect is better; And greatly simplify the structure of filter assemblies, reduce cost; In addition, carrying out filter assemblies, in clean regenerative process, the filter effect of filter assemblies can not being reduced, the service life of filter assemblies is greatly improved.Air purification method of the present invention, step is simple, and regeneration easy to clean, the dust in can extremely effectively purifying air, particle and pernicious gas, and the volume that can not increase air cleaning unit, saved space resources.
Concrete, by the dust in the paper mold membrane filtration air of the flexible, porous metal film structures in filter assemblies and particle in step b.Described flexible, porous metal film adopts application number to be that the flexible, porous metal forming recorded in the Chinese patent application of 201410608980.3 makes or adopt other similar approach existing to make.This flexible, porous metal film is the metal porous structure of matrix phase by the metal simple-substance of the metal simple-substance of solid solution alloy, face-centred cubic structure or body-centered cubic structure, there is quality light, long service life, the advantages such as regeneration easy to clean, the isolated by filtration requirement to air can be met, and ensure that the flexibility of this flexible, porous metal film is better.The metal simple-substance of described solid solution alloy, face-centred cubic structure or the metal simple-substance of body-centered cubic structure are existing metal structure or material.The paper mold membrane aperture of flexible, porous metal film structures is preferably 1 ~ 10 μm, learns through experiment, and the paper mold film in this aperture effectively can tackle dust and the particle that particle diameter is greater than 0.1 μm.The thickness of described paper mold film is 5 ~ 200 μm, and it is flexible better, and by cutting, the mode such as bending and welding is made into different shapes, meets different needs.The porosity of described paper mold film is 40% ~ 70%.Filtering requirement according to varying environment can adjust accordingly porosity, is ensureing, under the prerequisite that filter efficiency is higher, to make it have good gas permeability, reduce filtration resistance.The method adopts dust in above-mentioned paper mold membrane filtration air and particle, regeneration easy to clean, is ensureing that under the prerequisite that filter efficiency is higher, gas permeability is better, and filtering accuracy can reach 0.1 μm.
