Description
Technical field
The present invention relates to building fresh breeze device field, particularly, relate to a kind of suction type aeration device.
Background technology
The fast development of industry, environmental quality is greatly affected.Last year environmental monitoring display, China is one of the most serious country of air pollution index, and the quick-fried table of each metropolitan PM2.5 index, reaches the degree of severe contamination, and what stand in the breach is a few big city in Beijing, Shanghai, Guangzhou and Chengdu.Many parts of research reports are pointed out: the city gray haze number of days such as Shanghai, Guangzhou, Chengdu, Chongqing have accounted for annual 30%-50%.Municipal pollution is more and more serious, is more and more subject to people's attention the purification of air.
In existing house, in order to reach the purification to air, it adopts indoor air-purification device, directly purifies room air, but its needs are closed the doors and windows.Airtight space makes some people feel oppressive, and door and window closes the flowing making indoor people's impression less than wind, and the experience sense that existing air cleaning unit brings people is not good.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of suction type aeration device, and it utilizes principle of negative pressure to realize circulation and the purification of room air, when to purification of air, has the flowing of wind, makes people just as in natural environment, strengthens the comfort of user.
The present invention's adopted technical scheme that solves the problem is:
A kind of suction type aeration device, comprise the air exhausting device of being discharged by room air and convection current enters the fresh breeze device that room air carries out filtering, described fresh breeze device comprises housing, be arranged on air inlet on housing and air outlet, filter course between air inlet and air outlet, described filter course comprises the primarily efficient filter layer, medium air filtration layer, high efficiency filter layer, cellular activated carbon screen pack, cold catalyst screen pack and the formaldehyde screen pack that are arranged in order, and described air inlet is provided with filter.
The present invention utilizes the air of principle of negative pressure to indoor circulate and purify.Fresh breeze device is arranged on wall, and the air of indoor is discharged by air exhausting device, and make the air pressure of indoor air be less than the air pressure of outdoor air, now, outdoor air will flow into indoor automatically by fresh breeze device.Present air quality is very poor, need carry out treatment and purification to outdoor air, and primarily efficient filter layer is used for primary filter, filters 5 μm with dust particles; Medium air filtration layer adsorbs the particle dust of 1 μm-5 μm on the basis of primarily efficient filter layer, and it can effective decomposing volatile organic matters, preferably can adopt HEPA medium air filtration net; High efficiency filter layer adsorbs the particle of less than 0.5 μm on the basis of medium air filtration layer; Cellular activated carbon screen pack absorbs the peculiar smell in air and particle; Cold catalyst screen pack adsorbs various organic pernicious gas; Formaldehyde screen pack adsorbs the formaldehyde in air.Primarily efficient filter layer, medium air filtration layer, high efficiency filter layer are arranged setting successively, each layer adsorbs larger particles, moderate particle, comparatively granule respectively, compared to directly arranging high efficiency particulate air filter layer, the adsorptive pressure of each layer can be reduced, strengthen the absorption affinity to particle, also increase the cleaning cycle to fresh breeze device.The number of plies of the filter course of fresh breeze device is more, and it is comparatively large to the resistance of air circulation, thus air inlet to arrange enough large, but air inlet is comparatively large, easily makes impurity enter in the housing of fresh breeze device, therefore filter is set at air inlet, larger impurity is intercepted, ensures cleaning in housing; And impurity enters in housing, easily affect the flowing of air, namely filter is set at air inlet, also can ensures the flow velocity of air.
As preferably, in order to strengthen the clean-up effect to air, described high efficiency filter layer comprises the first high efficiency filter layer and the second high efficiency filter layer.Present people comparatively pay close attention to PM2.5 index, utilize the molecule of two-layer high efficiency filter layer to air to adsorb, and strengthen air purification effect, meet the air cleanliness requirement that people strengthen day by day.
As preferably, in order to the impression making fresh breeze device meet all kinds of people, described air outlet is provided with wind direction adjustment sheet.Utilize wind direction adjustment sheet to the adjustment entering indoor wind direction, meet the instructions for use of people.In use, some people does not like the sensation having wind flow, can regulate wind direction, makes it experience less than wind flow.
Further, in order to accelerate the flow velocity of wind, accelerating indoor fresh breeze speed or meeting the high request of some people to wind speed, described air inlet is provided with the air-supply arrangement accelerating air flow filter course.Because the number of plies of the filter course of fresh breeze device is more, it is comparatively large to the resistance of air circulation, utilizes air-supply arrangement to accelerate the flowing of wind.
As preferably, described formaldehyde screen pack is aluminium base honeycomb photo-catalytic filtering screen.Aluminium base honeycomb photo-catalytic filtering screen its adopt ozone reduction technology, clearance can reach far below national standard.
To sum up, the invention has the beneficial effects as follows:
1, the present invention utilizes the air of principle of negative pressure to indoor circulate and purify, and in use, room air and outdoor air circulate, and produces the flowing of wind, and wind speed is comparatively large, makes people just as in natural environment, strengthens the comfort of user.
2, fresh breeze device of the present invention its multiple filtration is adopted to outdoor air, greatly improve clean-up effect.
3, primarily efficient filter layer of the present invention, medium air filtration layer, high efficiency filter layer are arranged setting successively, each layer adsorbs larger particles, moderate particle, comparatively granule respectively, compared to directly arranging high efficiency particulate air filter layer, the adsorptive pressure of each layer can be reduced, strengthen the absorption affinity to particle, also increase the cleaning cycle to fresh breeze device.
