Rain effect fresh air machine

Abstract

The invention discloses a novel rain-effect air blower, and belongs to the technical field of air purification. The novel rain-effect air blower comprises a purifying barrel; a fresh air inlet and an purified air outlet are formed in the purifying barrel; a spraying system is arranged between the fresh air inlet and the purified air outlet; the spraying system comprises a plurality of spray nozzle layers which are arranged in top and bottom; the diameters of the water drops sprayed from the spray nozzles are sequentially reduced from top to bottom; water mist sprayed through the spray nozzle in the top layer can completely cover the water mist sprayed through the spray nozzle in the lower layer; a water storing area is arranged below the spraying area; a water inlet of a spraying water pump communicates with the water storing area; a draining opening is formed in the bottom point of the bottom end of the purifying barrel. The device has the advantages of being low in wind resistance, large in air volume, high in purifying efficiency and low in maintenance cost.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a rain-effect fresh air blower, which is mainly suitable for ventilators and air purifiers. Background technique [0002] Fog has existed since ancient times. It is formed by the condensation of water vapor contained in the air onto fine dust particles. The weathering of rocky soil in nature, volcanic ash, and combustion smoke are the main sources of fine dust particles in the air. After humans entered the petrochemical age, exhaust emissions from chemical plants, vehicle exhaust, friction between rubber tires and the ground, industrial kilns, and heating boilers made the dust particles discharged into the air more, finer, and more complex in composition. The finer the particles, the slower the sedimentation rate, making them diffuse over the surface for a long time to form haze. If a certain humidity is reached in the air, a mixture of fog and haze——haze is formed. T...

Problems solved by technology

[0005] Indoor air purifiers are mainly physical purification method and electrostatic adsorption method. The physical purification method mainly uses filter screen to filter, and the purification effect is relatively good. The disadvantage is that the wind resistance is large and easy to be saturated, the effect will be greatly reduced, and the cost of replacing consumables is high.

Electrostatic adsorption method also has a certain effect, but it is easy to generate ozone, which is harmful to human body

And the common shortcoming of above-mentioned two kinds of indoor air purifiers is: can only be used in the confined space, needs continuous circulation to filter the indoor air to purify gradually, because there is no supplement of fresh oxygen, use for a long time can cause indoor air hypoxia, and For fresh air with a large amount of outdoor pollution, the above-mentioned indoor air purifiers will be overwhelmed

[0006] The current fresh air ventilator meets people's requirements for fresh air by simply purifying the outdoor air and transporting it indoors. However, due to the large amount of outdoor air pollution, including particulate pollutants of various sizes, the purification method is demanding. If a HEPA-grade filter element is also used, it will soon be saturated, and then fail and clog

Therefore, the fresh air ventilators currently on the market are simple coarse filters, which are basically ineffective against PM2.5
