Air curtain generating device for dust fall of construction site road and using method thereof

Abstract

The invention particularly relates to an air curtain generating device for dust fall of a construction site road. The device is characterized in that the device comprises an air curtain generating cylinder, a water mist system, an air supply system, a main water pipe, a main air pipe, a water source and a fan, the water mist system and the air supply system convey air and water to a mixing cavityin the air curtain generation cylinder through a water mist spray head and an air spray head correspondingly, so that compressed air with water mist is formed in the air curtain generating cylinder, curtain-shaped wet mist airflow is sprayed out of the compressed air through the flow guide nozzle of the air curtain generating cylinder, rising of flying dust on the road surface is stopped after meeting the curtain-shaped airflow, the flying dust gradually descends to the road surface under the action of the water mist of the wet mist airflow, and therefore the purpose of dust falling is achieved. Pedestrians and vehicles are not influenced during operation of the device, road washing slurry is not generated, and water conservation and emission reduction are facilitated.

Description

technical field [0001] The invention relates to the field of environmental protection facilities on construction sites, in particular to an air curtain generating device for reducing dust on roads at construction sites and a method for using the same. Background technique [0002] With the strengthening of energy conservation and environmental protection control in our country, the control of dust on construction sites has become the focus and difficulty of urban air pollution control, and it has also become one of the key control contents of competent departments at all levels. Almost all construction sites today face the problem of dust control. [0003] At present, dust control on construction sites mainly adopts measures such as roadside spraying, artificial mobile watering, regional spraying with fog cannons or mobile spraying for dust reduction. Although these methods have good effects on dust control, there are still some disadvantages, such as large labor consumptio...
