Abstract
The invention discloses a positive pressure type fresh air system with the function of purifying fine particulate matter and harmful gas. The positive pressure type fresh air system with the function of purifying fine particulate matter and harmful gas is composed of an air inlet end (1), a primary-efficiency filter module (2), a draught fan module (3), a high-efficiency filter module (4), an adsorption module (5) for activated carbon, diatomite and the like, a negative ion generator (6), a fresh air distribution box (7), an air tube (8) and air feeding ends (9). Outdoor air sequentially passes through the primary-efficiency filter module (2), the draught fan module (3), the high-efficiency filter module (4), the adsorption module (5) for activated carbon, diatomite and the like, the negative ion generator (6) and the fresh air distribution box (7), and the outdoor air introduced from the air inlet end (1) is evenly fed into the indoor space through the air feeding ends (9) after being purified and processed. The positive pressure type fresh air system with the function of purifying fine particulate matter and harmful gas not only can efficiently remove the fine particulate matter and harmful and poisonous gas contained in the fresh air, but also can provide compositions such as negative ions which are beneficial to health of the human body, wherein the removal rate for the fine articulate matter with the diameter being greater than 2.5 micrometers is higher than 99%, and the positive pressure type fresh air system with the function of purifying fine particulate matter and harmful gas is especially suitable for medium and small closed space such as medium and long distance communication vehicles, hospitals, schools and families.
Description
Technical field
The present invention relates to a kind of VMC, more relate to a kind of positive-pressure type VMC that is applicable to medium and small space fine particle and cleaning harmful gas.
Background technology
Existing VMC has to be sent into or is drawn into indoor by outdoor air through simple filtration, can meet the needs of human body to fresh oxygen concentration, and can not effectively the poisonous and harmful elements such as bacterium, formaldehyde, dimethylbenzene, fine particle in air effectively be removed, thereby meet the injury of environmental pollution to health.
Fine particle refers to that in surrounding air, aerodynamics equivalent diameter is less than or equal to the particle of 2.5 microns, also claims PM2.5, can enter lung particle.It can be suspended in air the long period, and its content (concentration) in air is higher, just represents that air pollution is more serious.Although PM2.5 is content component seldom in earth atmosphere composition, it has important impact to air quality and visibility etc.Compare with thicker Atmospheric particulates, PM2.5 particle diameter is little, and surface area is large, active strong, easily attach poisonous and harmful substances (for example, heavy metal, microorganism etc.), and the time of staying in atmosphere is long, fed distance is far away, thus larger on the impact of health and atmosphere quality.
In February, 2013, national scientific and technical terminology validation board is by the Chinese called after fine particle of PM2.5.The chemical composition of fine particle mainly includes machine carbon (OC), elemental carbon (EC), nitrate, sulfate, ammonium salt, sodium salt (Na+) etc.
In various industrial process, heat supply, the gastronomical process such as generating, metallurgy, oil, chemistry, textile printing and dyeing, flue dust and production technology coal-fired and combustion gas or fuel emission are disposed to airborne waste gas.When all kinds of vehicles use fuel in running to the tail gas discharging in atmosphere.In these waste gas, also exist the various organic matters such as benzene, dimethylbenzene, formaldehyde, ether, sulfur-bearing, chlorine to the toxic left and right of health.These pernicious gases are with oxygen diffusion, and the medium and small space such as house, hospital, the vehicles of living in city and industrial area there is no effective removal device, to guarantee health.
The present invention is applied to medium and small space and for above-mentioned harmful fine particle, bacterium, organic gas and other harmful substances, carries out the VMC of high-efficient purification.
Accompanying drawing explanation: accompanying drawing 1 is patent structure schematic diagram of the present invention.
Summary of the invention
The present invention relates to a kind of VMC, more relate to a kind of positive-pressure type VMC for medium and small space fine particle and cleaning harmful gas.
Technical scheme of the present invention is as follows:
The present invention introduces indoor airduct by outdoor new wind by air intake, through take the roughing efficiency air filter that nylon or nonwoven be filter core, filters, and removes 5 microns of above coarseparticulates of diameter, and solvable dust quantity is larger, and this process is called as the first order and filters.
Then through blower fan, deliver to polypropylene filter material or all-glass paper filtrate is filter core high efficiency particulate air filter, can filter 1 micron of above particle of diameter, thereby adsorbing and have a large amount of poisonous and harmfuls can directly enter human lung's fine grained high efficiency filter in air.
If have the organic gas that cannot be filtered on a small quantity in new wind, then can lean on it to be adsorbed compared with bigger serface through porous medias such as layer of active carbon, diatomite, thereby guarantee that the wind of air-supply end is enough clean.
Generally speaking, people every day need to approximately 13,000,000,000 anions, and our room, office, the environment such as public place of entertainment, can only provide approximately 1---and 2,000,000,000.Anion can not only facilitate human body to synthesize and vitamin storage, the physiological activity of strengthening and human activin, therefore it is otherwise known as " air vitamin ", thinks that it,, as the vitamin of food, has very important impact to the vital movement of human body and other biological.In medical circle, it is the effective means that has killing pathogenic bacteria and purify air that anion is identified.The present invention installs anion generator on the pure fresh air pipeline through filtering, to meet the needs of the places such as room to negative oxygen ion.
The final fresh air through filtration is delivered to by distributor the confined space that each is required as required.Guidance panel and display floater, for opening or close the operation conditions of cleaning system, adjusting power of fan, display system integral body and each parts.
Tradition VMC is to be generally combined with air-conditioning system, for system ventilations such as building and villas, needs.Compare with existing VMC, the present invention is applicable to all size space, higher to the degree of purification of air, 1 micron in new wind above particle and organic gas all thoroughly can be removed, and increase the negative ion concentration in new wind, be more of value to confined space human body physically and mentally healthy.
