Fog gun machine for dust fall of urban atmospheric environment

Technical Field

The invention relates to the technical field of dust settling equipment, in particular to a fog gun machine for settling dust in an urban atmospheric environment.

Background

Along with the continuous acceleration of urbanization process, environmental problem is more and more serious, especially all kinds of buildings and heavy industry concentration district, and a large amount of dust is diffused in the air, leads to air quality to descend constantly, consequently these places adopt the fog gun machine to carry out the dust fall and handle usually.

The current fog gun machine uses high-pressure water pump, atomizing nozzle atomizes water, recycle fan amount of wind and wind pressure and send the water smoke to far away distance, when making the water smoke reach far away distance, adhere to the dust in the air, make the dust descend, but current fog gun machine is owing to set up the shower nozzle at the air outlet, the shower nozzle is at the in-process that sprays the water smoke, partly water smoke can not contact with the wind of fan, but the bottom surface is wandering around, can waste the water resource like this, and can also reduce the volume of output water smoke, thereby lead to the dust fall effect unsatisfactory, secondly, current fog gun machine receives the restriction of self structure, if need send the water smoke to far away position, just need increase the power of fan, but so, the electric quantity of consumption will greatly increased.
