Abstract
The invention provides a novel indoor air purification device. Water or an aqueous solution is used for absorbing various types of gas and granular pollution components in air, so that the aim of purifying the air is fulfilled; a Venturi throat opening is formed in an air channel; when the gas passes through the throat opening, the speed of gas flow is obviously increased, and high shearing force is formed in the gas flow, so that liquid entering the Venturi throat opening is sheared into extremely thin fog drops; after leaving the Venturi throat opening, the gas flow is slowed down and forms strong turbulent fluctuation, so that particles in the air and the extremely thin water drops can be in full contact and collision, and the particles in the air are transferred into liquid; the water drops in a turbulent fluctuation region also collide, and the water drops are re-enlarged, so that the water drops can be removed from a gas-liquid separation chamber, and the gas pollution components in the air are dissolved in the liquid so as to be absorbed and removed.
Description
Technical field
The present patent application relates to a kind of Novel indoor air purifier, mainly utilizes venturi (Venturi) effect and cleaning solution principle of absorption to carry out washing, purifying to room air, has the features such as volume is little, efficiency is high, clean and energy-conservation.
Background technology
The pollution of room air comes from the reason of indoor and outdoors two aspects.What indoor reason discharged in coating for wall surface, furniture paint, carpet or plank binding agent, all kinds of cleaning agents etc. comprises the volatile organic matter formaldehyde and dimethylbenzene.People live in new house in the near future easy ill room syndrome (sick building syndrome) be exactly not smooth owing to ventilating in new house, in air, be full of that more these gases cause; In addition all kinds of smells that enter room in all kinds of smells, toilet water closet and the sewer ventilation shaft discharging in culinary cuisine process, (comprise H
2s, two mercaptan, the organic or inorganic gases such as indoles), gas that smoking produces etc. has also formed the important sources of indoor polluted gas; The food of the sweat gland of human body, pet and storage also can distribute a lot of gas componants in room air in addition.In room air, the source of contained dust has: the particulate pollutant discharging in smoking and kitchen fume, people and pet exuviae skin and hair, each quasi-microorganism (comprising bacterium and mould and acarid etc.) of growing on air and the surface of solids is also the important sources of dust in room air.
Outdoor reason is mainly each pollutant in outside atmosphere through ventilation or aircondition or door and window and enters indoor.Outdoor reason is subject to the impact of outside atmosphere quality and degree has larger difference.The decline of China recent years atmosphere quality, the concentration increase of airborne finely ground particles PM2.5 particle causes haze weather to increase, and the concentration of indoor PM2.5 particle is improved greatly.In addition also likely formed, the important sources of indoor particle thing by people's the entrained dust of entering house of clothes, shoes and skin.
In the face of the control of indoor environmental quality, existing many different air purifiers are available in the market.These purifiers mainly use solid filtration media that air is filtered and purified.As adopt filter course and the foamed filter material of braiding or non-woven fiber to carry out the particle in filtered air.The mechanism of filtering comprises to be held back, collide, precipitates and adsorbs.In order to increase the specific area of filtration, reduce the service time of filtration resistance and prolongation filter screen, filter screen is processed to collapsed shape conventionally.Above-mentioned filter medium generally can not effectively be removed airborne gas componant, the removal of gas componant is mainly used the natural or artificial sorbing material such as activated carbon and zeolite, the mechanism of removing is mainly physics or chemisorbed, thereby the surface that by physics or chemical action, gas molecule is adsorbed on to adsorbing medium separates gas componant from gas.
Except the indoor air-purification device of above-mentioned use adsorbing medium, United States Patent (USP) (US Pat No6,280,691, US Pat No.4,138,220, US Pat No5,447,693, US Pat No5,252,299) disclosed the air cleaning unit that uses catalytic oxidation.For catalyst (Metal Palladium or aluminium) is played a role, these purifiers all must arrange air heating apparatus, and air themperature is heated to 200-500 °F.These catalytic oxidizing equipments generally can be removed airborne CO, NOx, SOx, H well
2s, NH
3and most of organic matter, but in order to recover energy, the air of heat also must reduce temperature by heat-exchange device to get off.But it is harmful to health that catalytic oxidation process may produce a certain amount of ozone, active carbon filtration layer also must be set conventionally ozone is removed.
Also have a class airhandling equipment to press to strengthen clean-up effect with high tele-release.Under high voltage electric field, electric discharge phenomena can occur, the airborne oxygen of electron excitation producing produces anion; Anion has very high oxidability, can make the oxidized decomposition of airborne organic matter, reaches the object purifying air, and anion also likely changes the electrical of particle dust surface simultaneously, and particle dust is easily filtered.This class purifier, except needs adopt potential device, has electrion parts, also can produce ozone simultaneously, must adopt active carbon or other sorbing material to remove.
Also have a class airhandling equipment to adopt ultraviolet photooxidation reaction device, these class methods, except using ultraviolet lamp tube, also must be used catalyst (metal platinum).Metal platinum is that noble metal is expensive, and the ultraviolet ray producing is as improper in shielded, and is irradiated to human body skin and may causes and burn and cutaneum carcinoma after leakage.
Patent US Pat No5,509,946 have disclosed a kind of filter, and water and active carbon and other filter medium are purified the air of a room.Built-in water pump is extracted water out from water tank, then by a water distribution head, water is injected in air flue, and makes filter medium wetting, thereby airborne dust and water miscible gas componant are transferred to and in water, made air cleaning.But this device is limited to the removal effect of particle and gas componant, still need to rely on use fiber filter media, foamed filter medium and activated carbon adsorbent, just can reach desirable effect.The above-mentioned catalytic oxidation of this device relative usage, anion and photocatalytic oxidation, make water help absorb gas and particulate component.But the method can not be removed water-fast gas componant, receive the restriction of filter medium specific area simultaneously, very limited for the removal effect of fine particle.
In sum, existingly purifier usedly generally remove airborne dust with fiber-like or foam class medium, adopt activated carbon to remove gas pollutant.In order to reach the effect of good removal dust, especially remove fine particle (sub-micron or approach the particle of submicron order) and generally must use thickening and/or fine and close filter material layer, certainly will cause like this air to pass through the resistance of filtering layer large, often need to adopt larger filter area to reduce filtyration velocity and the pressure loss of air.After filtrate uses, must often change, otherwise not only resistance can further increase, and dust and bacterium that part is held back can come off and penetrate filter material layer, removal effect is lost completely.Often replace filtrate and can increase use cost for user.And use the wet method (US Pat No5,509,946) of shower water to filter, and the drop size causing due to spray is still larger, and assimilation effect is subject to the specific area restriction of moistening medium, little for the removal effect of molecule dust.
The existing method that removes gas pollutant with the natural or artificial sorbing material such as activated carbon or zeolite, often be subject to the restriction of indoor air cleaner volume, the use amount of sorbing material can not be too many, make the adsorption effect of device undesirable, and the surface of sorbing material is easily adsorbed saturated, as regeneration or replacing not in time, will lose effect completely.
Thereby adopt anion to make the removal of the electronegative increase of particle surface particle, although can increase to a certain extent the removal of particle, reduce filter course thickness.Produce negative electrical charge and need to use electrion, the manufacturing cost of device increases, and likely produces ozone simultaneously, active carbon filter net must be set and remove ozone.Use photochemical catalytic oxidation and the high temeperature chemistry catalytic oxidation of uviol lamp also to have similar problem, need to use uviol lamp or air heater, also need to use catalyst, manufacturing cost is higher simultaneously, also likely produce ozone, must use active carbon filter net to be removed simultaneously.
