Urban air purifying device

Abstract

The invention discloses an urban air purifying device comprising a shell. A high-pressure fan is installed in the middle of the shell. The shell is downwards connected with an air gathering shell. Theair gathering shell downwards expands in the radial direction and forms an air inlet at the lower end. Multiple layers of air filtering nets are installed in the air gathering shell. The shell is upwards connected with an air discharge hood. The air discharge hood changes from bottom to top in the radial direction to form a flat air discharge opening. An anion generator and multiple atomizing sprayers are installed at the flat air discharge opening. The urban air purifying device has a good water atomizing effect, is high in lift and haze settlement ratio, filters and cleans particle matter and saves water resource and energy, and the urban air purifying device avoids the situation that the ground becomes muddy, and travel is influenced.

Description

technical field [0001] The invention relates to a device, in particular to an urban air purification device. Background technique [0002] With the development of social economy and production, smog will often appear in many areas in northern my country. Haze is PM2.5 and other size particles, dust, aerosols and other particles floating in the atmosphere. It is a weather phenomenon that occurs under a relatively stable state of certain temperature and humidity conditions. Haze has caused serious damage to people's health and daily life. greater impact. At present, the municipal environmental sanitation department mainly purifies the air by spraying water to reduce the hazards of smog. When spraying water, the water is sprayed into the air, and the water is dispersed into fine water droplets, which will cause the particles in the air to combine and fall to the ground with the water. This method has the following disadvantages: low sedimentation rate and water utilization r...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: low sedimentation rate and water utilization rate, fine water droplets cannot be further differentiated, and under the contact area with smog particles, they cannot effectively settle the smog particles, the removal rate of smog is poor, and the amount of water sprayed is large , not only leads to low effective utilization of water, wasting water resources, but also makes the road surface more muddy, which is not convenient for people to travel, and the large amount of water spraying also leads to high energy consumption
