Description

Urban air purification device

Technical Field

The utility model relates to a device particularly relates to an urban area air purification device.

Background

Along with the development of social economy and production, haze phenomena often appear in many areas in the north of China. The haze is particles such as PM2.5 and the like which float in the atmosphere, dust, aerosol and the like, and is a weather phenomenon generated under a relatively stable state under a certain temperature and humidity condition, and the haze has great influence on the health and daily life of people. At present, municipal environmental sanitation departments mainly purify air by means of water spraying, water sprinkling and the like, and haze harm is reduced. When water is sprayed, the water is sprayed into the air and dispersed into fine water drops, so that particles in the air are combined and fall on the ground along with the water. This approach has the following disadvantages: sedimentation rate and water utilization rate are low, and tiny water droplet is because of can not further differentiation, with haze granule area of contact under, can not form effectively subsiding to the haze granule, and the haze clearance is relatively poor, and the water spray volume is big, not only leads to water availability factor lower, wastes water resources, makes the road surface comparatively muddy moreover, and the people of not being convenient for go on a journey, and the water spray volume still leads to the energy consumption high greatly.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a city air purification device, the device is good to the water atomization, and the lift is high, and is high to the haze settlement rate, and the energy has also been practiced thrift to particulate matter filtration purification and water economy resource to do not make the muddy and influence the trip in ground.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides an urban area air purification device, includes the casing, its characterized in that, the casing middle part ann has high pressure positive blower, and the casing links to each other with holding in the air the shell downwards, hold in the air the shell radial expansion downwards and form the air intake at the lower extreme, be equipped with multilayer airstrainer in holding in the air the shell, the casing upwards links to each other with the exhaust hood, the exhaust hood forms flat air exit along radial change from bottom to top flat air exit department ann has anion generator and a plurality of atomizer, each atomizer warp the pipeline and links to each other with high pressure water pump.

Preferably, the length of the air outlet is 1 ~ 20 m, the width of the air outlet is 0.05 ~ 0.5.5 m, and 50 ~ 2000 0.5-micron atomizing nozzles are arranged in the air outlet.

Preferably, the lower part of the exhaust hood is a circular opening and is connected with the shell, and the flat exhaust opening is formed by upwards extending the circular opening along a diameter direction and contracting the circular opening along a direction perpendicular to the diameter direction.

Preferably, the diameter of the high-pressure fan is 0.3 ~ 5 m, and the power is 0.45 ~ 120 kw.

Preferably, the multilayer air filter screen comprises a PM20 filter screen, a PM10 filter screen, a PM5 filter screen and a PM2.5 filter screen from outside to inside in sequence.

Among the above-mentioned technical scheme, the air exit wind channel can be concentrated the air of inhaling and send out, and powerful wind pressure can be produced to the powerful driving force of cooperation high pressure positive blower. Set up a plurality of atomizer at the air exit, can atomize water, then by high wind pressure propelling movement to aerial, solved spray in the past if too thin then can't reach the difficulty of higher lift. The air exit sets up anion generator, makes spun water smoke carry static, can be better combine with the haze granule, the degree of refining and the cooperation of water smoke take static effect, high wind pressure propelling movement for compare with equipment in the past, the hydroenergy of the same quantity can promote the haze settlement rate more than the six times, has promoted purifying effect and water utilization ratio, and can not make the road surface muddy after water smoke falls to the ground, does not influence the trip. The multilayer air filter screen can filter the air, and clean air stops secondary raise dust pollution.
