Abstract
The invention relates to a method for keeping indoor air clean. The method for keeping the indoor air clean includes steps of using an air purification device to perform purification treatment on the indoor air of a building, closing a door and a window in the building, keeping airtight performance of the door and the window, starting a draught fan, guiding indoor circulation air into the building through an air inlet, guiding outdoor air into the building through a fresh air pipeline, and mixing the outdoor fresh air with the indoor circulation air so as to generate mixing air. A purification filter section filters 90% of dust, suspended particles and air pollutants, which are larger than 0.5 micro meters in diameter, out of the mixing air so as to generate clean air. A clean air efficiency processing section sterilizes the clean air, removes odor of the cleaning air, regulates temperature of the clean air, and thereby generates pure air. Positive pressure pure air is generated after the pure air is processed by a device power section and a rectification section. The positive pressure pure air enters the building through a clean air output section and then mixes with the indoor air of the building, and thereby keeps pressure of the indoor air higher than outdoor atmospheric pressure.
Description
Technical field
The present invention relates to method and the air cleaning facility of air cleaning in a kind of holding chamber, belong to Techniques for Indoor Air Purification field.
Background technology
Along with the development of economy, air pollution increases the weight of day by day, and especially in air, PM2.5 content constantly increases.PM2.5 refers to that in air, diameter is less than or equal to the fine particle of 2.5 microns.It can be suspended in air the long period, and it has important impact to air quality and visibility etc.
Compared with thicker Atmospheric particulates, PM2.5 particle diameter is little, and area is large, active strong, easily attach poisonous and harmful substances (such as, heavy metal, microorganism etc.), and the time of staying is in an atmosphere grown, fed distance is far away, thus larger on the impact of health and atmosphere quality.The harm of the haze weather caused by fine particle to health is even larger than sandstorm.
The particle that fine particle diameter is more than 10 microns, outside the nose that can be blocked in people; And the fine particle of PM2.5, diameter is equivalent to 1/10 size of human hair, is not easily stopped.Directly can enter bronchus after being inhaled into human body, the gas exchanges of interference lung, causes the disease comprising the aspects such as asthma, bronchitis and cardiovascular disease.
PM2.5 particle enters the ability that blood can damage hemoglobin delivery of oxygen, concerning the patient of anaemia and blood circulation disorder, may produce serious consequence.PM2.5 also can become the carrier of virus and bacterium, for the propagation of respiratory infectious disease is added fuel to the flames.The physiological structure of human body determines to PM2.5 without any filtration, obstruction ability, and PM2.5 is to the progress of the harm of human health along with medical technology, progressively exposes the one side of its terror.Along with growth in the living standard and people are to the concern of health environment, air quality more and more becomes the emphasis that people pay close attention to.Therefore, the method and the air cleaning facility that propose air cleaning in a kind of holding chamber is needed.
