For a long time, in the aspect of air quality supervision caused by dust emission in construction sites, because real-time monitoring data cannot be obtained or direct data corresponding to facts cannot be obtained after reporting is received, the air quality supervision is always very troubling for government supervision departments. According to the monitoring and analysis of environmental protection departments in Beijing, the dust pollution accounts for about 15.8 percent of PM2.5 sources. In six main pollution sources of Nanjing, the dust raising proportion is the largest and reaches 37.28%. The impact of construction site dust emissions on air quality is of increasing concern because of the generally low emission levels of such dust and the tendency to concentrate in densely populated urban areas.

In order to effectively control the dust emission of the construction site, the construction site is generally provided with dust removal equipment, which is commonly called a dust remover and is a device for removing or reducing the content of fly ash in flue gas. The types of dust removing devices can be classified into a cloth bag dust removing device, a cyclone dust removing device, a wet dust removing device, an electrostatic dust removing device and a desulfurization dust removing device. At some places that dust concentration is great, if adopt sack dust collector to remove dust, just so can because the dust is more, the sack just stops up very fast, needs people often to go to change or overhaul to lead to intensity of labour great, this effect that also can reduce the dust removal moreover. No matter dust concentration is high or up to standard after dust collector opens, dust collector all can work always, and this has also wasted certain unnecessary power consumption, and ordinary dust collector is not very good to the dust removal effect of air simultaneously. However, the equipment adopting the spraying mode for dust removal has large water resource consumption and can not effectively absorb dust, and once the sprayed water is evaporated, the dust falling on the ground can aggravate the dust raising.
