Abstract

An omni-directional city air purifying system comprises buildings located in a city, wherein fireproof doors (1) are arranged in fire-escape stairs of the buildings. The omni-directional city air purifying system is characterized in that a plurality of through holes (2) are formed in a door leaf of the uppermost or lowest fireproof door (1) in the fire-escape stairs, a position, corresponding to the position where the through holes are formed, of the back of the door leaf is provided with a framework (3), the outward face of the framework is grids (7), a fan (6) driven by a motor (5) is arranged in the framework, at least one filter net (4) is arranged between the fan and the through holes of the uppermost or lowest fireproof door, a position, corresponding to the position where the through holes are formed, of the front of the door leaf is provided with a hinge louver, and the hole diameter of the filter net (4) is smaller than 2.5 micrometers. When the omni-directional city air purifying system is carried out in a large scale, influences of air with exceeding PM2.5 on people living in the buildings of the large city can be reduced in the most economical mode as far as possible.

Description

A kind of comprehensive urban air cleaning system

Technical field

The utility model relates to a kind of air cleaning system, especially relates to a kind of comprehensive urban air cleaning system.

Background technology

Now, the air that PM2.5 exceeds standard, become the healthy killer of people who lives in metropolis.PM2.5 refers to that in atmosphere, diameter is less than or equal to the particle of 2.5 microns, also referred to as entering the lung particle.Its diameter be less than the people the hairline thickness 1/20.Although PM2.5 is content component seldom in the earth atmosphere composition, it has important impact to air quality and visibility etc.Compare with thicker Atmospheric particulates, the PM2.5 particle diameter is little, is rich in a large amount of poisonous and harmful substances and the time of staying in atmosphere is long, fed distance is far away, thereby larger on the impact of health and atmosphere quality.

The solution that PM2.5 exceeds standard, except reducing coal fired power generation and vehicle exhaust, temporarily also do not have solution thoroughly.Under these circumstances, how could reduce most economical and most possibly and live in people in the high building of metropolis and be subject to the impact of the air that PM2.5 exceeds standard, become the problem that people need to study.

Also have, because the influenza virus of new variant constantly occurs, pre-anti-virus by airborne method in, except indoor local air sterilizing and purifying, how reducing and live in people in the building of metropolis and avoid the impact of influenza virus and pernicious gas, is to need the problem that solves equally.

The utility model content

Technical problem to be solved in the utility model, just be to provide a kind of most economical and reduce most possibly and live in people in the high building of metropolis and be subject to the comprehensive urban air cleaning system of the impact of the air that PM2.5 exceeds standard.

Solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of comprehensive urban air cleaning system, comprise and be positioned at incity, city building, be provided with labeled door in the stair that cock off of building, it is characterized in that: go up most in the described stair that cock off or under labeled door on have numerous through holes, door leaf back correspondence has through hole and is provided with framework, and the outside of framework is grid, is provided with the fan by driven by motor in framework, between fan and labeled door through hole, be provided with at least one screen pack.

On the basis of the above, the utility model can also be done further improvement:

Described door leaf front correspondence has through hole and is provided with hinged shutter, and just as exhaust fan for household, during work, hinged shutter is blown afloat exhaust by air-flow, and while not working, hinged shutter closes and prevents that air-flow from passing through.

The aperture of described screen pack is less than 2.5 microns.

The course of work:

The fan that vent was gone up or walked down to the ladder that cocks off most is drawn into the air of outside in building, and during through screen pack, air is filtered to purify and enters in resident family, discharges from escape route and tenant's window finally.Like this, such with regard to similar central heating, can the airborne dust of filtration, purification, can exempt again every household air filter impact disadvantage attractive in appearance is installed on window.

beneficial effect: due to after the Yi Zuo building installed above purifier, in building, air produces negative pressure, the building peripheral air can flow in building, formed air circulation, building is as having become a huge air purifier like this, air process in the peripheral certain limit in building is purified, if device more than therefore installing in Cities with Great Population Mei Zuo building, situation just as placed huge air cleaner in city scope with being evenly distributed, the just impact of PM2.5 in the purifying city air on a large scale, if add air sterilization technique at purifier again, more can reduce on a large scale the impact of influenza virus and pernicious gas in urban air.

A large amount of enforcements of native system, can be most economical and reduce most possibly and live in people in the high building of metropolis and be subject to the impact of the air that PM2.5 exceeds standard.

In figure: 1-labeled door, 2-through hole, 3-framework, 4-screen pack, 5-motor, 6-fan, 7-grid, the hinged shutter of 8-.

The specific embodiment

Comprehensive urban air cleaning system embodiment one of the present utility model, comprise and be positioned at the numerous building in incity, city, the building of one of them cock off in stair and are provided with labeled door 1(referring to Fig. 1), referring to Fig. 2 and Fig. 3, cock off in stair on the labeled door of going up most and have numerous through hole 2, door leaf front correspondence has through hole and is provided with hinged shutter 8, and during work, hinged shutter is blown afloat exhaust (Fig. 2) by air-flow, prevents on hinged shutter automatic pressing while not working that air-flow from passing through (Fig. 3).

Door leaf back correspondence has through hole and is provided with framework 3, and the outside of framework is grid 7, is provided with the fan 6 that is driven by motor 5 in framework, between fan and labeled door through hole, is provided with screen pack 4, and the aperture of screen pack is less than 2.5 microns.

Embodiment two shown in Figure 4, only be with embodiment one difference that labeled door 1 is located in the stair that cock off and descend place most.
