Abstract

The invention relates to a new method for isolating haze and a novel haze protection mask. On the basis of the principle, the haze in a hazy weather is basically formed by moisture sol and moisture gel, and the granularity of the haze ranges from 10 micrometers to 90 micrometers. Nanometer super-hydrophobicity materials are adopted so that the sol and the gel can be effectively isolated. The effect of filtering poison and harmful gas of the haze is accordingly achieved. Compared with a traditional mask, the mask has the advantages that the poison and harmful gas and solid particulate matter with the granularity smaller than 2.5 micrometers can be effectively filtered. Meanwhile, passing of oxygen and nitrogen in air is not influenced. The wearing comfort is guaranteed.

Description

A kind of intercept haze method and nanometer haze intercepts mouth mask and haze intercepts air purifier application

Technical field

The present invention relates to a kind of method and the nanometer haze obstruct mouth mask thereof that intercept haze.

Background technology

Fog is the steam droplet because air is formed under low temperature and high humidity, and the granularity of this droplet is greatly about 10-90 micron.Haze refers to the particulate matter suspended in air, and this particulate matter can be solid matter, also can be the particulate matter that gaseous matter and other matter interactions are formed.The meteorology definition of haze is that a large amount of imperceptible particulate matters etc. swim aloft equably, and the air making horizontal visibility be less than 10 kms generally has research of chaotic phenomenon, makes the micro-band of bright thing at a distance yellow, red, makes the micro-band of dark thing blue., soot or salt grain aggregate, make air muddy, horizontal visibility is reduced to a kind of weather phenomenon of below 10km.Haze is the portmanteau word of mist and haze.Refer under low temperature and high relative humidity weather conditions, the fog of formation and and haze material combine the suspension moisture being formed with toxic.

Traditional idea thinks that haze particulate matter is that particle diameter is less than 2.5 solid matters (also claiming PM2.5).In reality detects, finding that the virtual condition of the material forming haze is substantially for being (1). solid particle size is less than the mixture that 2.5 solid matters and fog steam are mixed to form, be referred to as aeroge or hydrogel, (2). also there are gaseous matter (the mixture aerosol be mixed to form with fog or the hydrosol.This gaseous matter has the aldehyde, phenol, peroxide, organic acid etc. of hydrocarbon (HC), nitrogen oxide (N0x), carbon monoxide (CO), carbon dioxide (C02), sulfur dioxide (S02), hydrogen sulfide (H2S) and trace.

The particle diameter of the hydrosol and hydrogel and the grain diameter of fog water droplet close, be all about 10-90 micron.

Owing to containing a large amount of virulent material in haze.These harmful toxic matters directly can enter the alveolar even septicemia victimization body of human body.Human body is caused to suffer from respiratory disease, lung cancer and cardiovascular and cerebrovascular disease etc.Thus preventing haze from invading human body is a great problem.The method of current employing is the method worn mouth mask He wear a gas mask.Because good breathing mask is expensive and wear complexity, because comparatively actual mode adopts to wear mouth mask.

Mouth mask had on the market is the mouth mask of anti-solid particulate matter PM2.5 substantially at present.Its principle is by the fineness of encryption mouth mask fiber and density substantially thus rice intercepts solid particulate matter.Although the actual effect of such mouth mask may reach intercept PM2.5 solid particle, on the one hand because overstocked fiber causes people to have difficulty in breathing, cause and use inconvenience; On the other hand, this mouth mask cannot intercept the toxic gas existed with aerosol hydrosol form.

Summary of the invention

Core of the present invention is based on following 3 points.First the present inventor finds two forms that haze weather harmful substance exists: (1). aerosol, or claim hydrosol form; (2). aeroge or title hydrogel form.It two is that the present inventor finds that nano superhydrophobic material can effectively intercept the hydrosol and hydrogel, does not affect again the gas permeability of barrier material simultaneously; (3). adopt this super-hydrophobic barrier material to make to receive wooden haze to intercept mouth mask, can effectively intercept haze and be sucked by human body.

Super hydrophobic material refers to that material surface has the structure of similar lotus leaf surface.This structure is the micro-bump structure having nanometer scale at material surface, and this structure can adsorb one deck gas molecule, makes to form a gas air cushion at material surface.Such water or steam first touch the gas molecule pad of this material surface when contacting this material.Form very strong surface tension, and very large surface contact angle.Thus reach very strong and refuse water or hydrophobic effect.

The manageable textile fabric surface of this hydrophobic material, becomes super-hydrophobic fabric.If the fibre fineness of this super-hydrophobic fabric acquires a certain degree, it just will not refuse water, also have the function of refusing steam simultaneously.Really realize weaving face fabric permeable watertight vapour.This super-hydrophobic fabric is made nanometer haze and intercept mouth mask, then can realize intercepting haze but the effect not affecting breathing.Its principle is stated as follows.

Nanometer barrier fabric and make nanometer haze and intercept mouth mask and intercept aerosol hydrosol principle: in haze, water-soluble gas or water-insoluble gas and steam combine the aerosol that formed or hydrosol particle diameter is generally 10-90 micron.As everyone knows, for general mouth mask, gas molecule can be unimpeded helpless by general mouth mask.Although aerosol and hydrosol particle diameter are comparatively large, are attached to after on mouth mask at it, under the pressure of human exhaled breath, can deformation be passed through, be sucked by human body by mouth mask.Intercept mouth mask for nanometer haze, situation is just completely different.First, when the aerosol hydrosol contacts with mouth mask, mouth mask surface can not be sticked to, and the globule can be formed on surface, and fall under gravity.Human body can not entered by mouth mask again along with expiration.

The surface contact angle of what the ultra-hydrophobicity characterizing nanometer barrier fabric adopted is material and water.The material that contact angle is larger, water droplet more easily forms the spherical globule on its surface, larger to the repellency of water, and barrier is better.

Nanometer barrier fabric and make nanometer haze and intercept mouth mask and intercept aeroge hydrogel principle: in haze, solid particulate matter and steam combine the aeroge that formed or hydrogel particle diameter is also generally 10-90 micron.And in fact the particle diameter of solid particulate matter is very little, endanger the larger particle being greater than 2.5 microns for particle diameter, i.e. PM2.5.General mouth mask, the mouth mask of current commercial type is all intercept PM2.5 by barrier method.Do like this and may have certain barriering effect, its shortcoming is that the gas permeability of mouth mask is deteriorated, and is not suitable for long periods of wear, is also not suitable for old man and child wears.As long as nanometer haze intercepts, mouth mask design is upper ensures that mouth mask can filter out particle diameter at the aeroge of 10-90 micron or hydrogel, can reach the effect intercepting haze PM2.5 particle.Can not as common mouth mask, fabric fibre is too fine and close, causes the phenomenons such as impact breathing.Same principle can be applicable to conventional air cleaners.Air purifier generally has inlet air filtration net.By this screen pack through the nanometered disposal of this superhydrophobic characteristic, the haze barrier properties making this screen pack have this patent to tell, makes traditional air purifier become haze air purifier.In actual applications, can add the adsorption layer of one deck or multilayer in this nanometer barrier layer, the material in adsorption layer can be active carbon, or alkalescent material, as: sodium carbonate, sodium acid carbonate, NaOH, potassium hydroxide etc.And also can consider to add one deck or multilayer stenlizing layer, sterilization material in nanometer barrier layer, can be traditional sterilization material, also can be nano material.As: Nano Silver, nano photo-catalytic, and other organic or inorganic sterilization materials etc.
