Method and facility for carrying out electrostatic precipitation on municipal engineering through construction fences

Abstract

The invention discloses a method and facility for electrostatic dust removal of municipal engineering by using construction enclosures. The surface of the metal plate enclosures on both sides of the construction site is covered with an insulating layer, and the metal plate enclosures on both sides are guaranteed to be free of dust. The conductive objects are connected to each other; it also includes a low-voltage DC safety power supply. The positive and negative poles of the low-voltage DC safety power supply are respectively connected to the metal plate enclosures on both sides. After power on, the entire construction area forms an electrostatic field; above the metal plate enclosure Water pipes and multiple nozzles are installed, and the water pipes are connected with fire hydrants or urban water pipes, and are used to spray dust to large areas or high-density dust. The present invention utilizes the negative charge characteristic of the dust itself, collects materials on the spot, covers the enclosure on the construction site with an insulating layer, and then connects a low-voltage safe DC power supply, so that the dust can be collected by directional movement autonomously under the action of the electric field force. It achieves the purpose of active dust removal and opens up a new way for the dust removal work of municipal engineering.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to municipal engineering dust removal technology in engineering sites such as road renovation, road crushing, and soil excavation. Background technique [0002] In municipal engineering, during the excavation of soil such as road construction, road renovation, pipeline trench excavation, and building foundations, floating pollutants such as flying dust are easily produced, and flying dust at construction sites has become the main cause of urban smog One of them poses a serious threat to the health of citizens living around and construction workers on site. At present, sprinklers are generally used to control the dust on the site, but the sprinkling area of ​​the sprinkler is limited, and the traffic capacity of the sprinkler on the construction site is limited, resulting in unsatisfactory dust removal effect. [0003] In the above-mentioned projects, for the sake of construc...
