Dust treatment system for truck construction site

Abstract

The invention discloses a truck construction site fugitive dust treatment system, which is characterized in that it comprises a fugitive dust suction device, a mechanical transmission device for transmitting the power of the truck drive shaft to the suction fan, a filter device for filtering large particles in the fugitive dust, and humidifying the fugitive dust and air. It also has a water washing device that dissolves soluble substances in the dust, and an electrostatic condensation dust removal device that removes inhalable particles in the dust. The present invention is aimed at the application occasions of construction site dust, and effectively realizes the removal of inhalable particles and solid large particles in the dust; the present invention is energy-saving, environmentally friendly, and low in cost, making construction site trucks a mobile clean source, and effectively reducing construction site dust pollution.

Description

technical field [0001] The invention relates to the technical field of construction site dust treatment and the technical field of cohesive electrostatic dust removal, and more specifically relates to a dust treatment system applied to truck construction sites. Background technique [0002] With the rapid development of my country's construction industry and road transportation industry, the problem of dust pollution on construction sites has become increasingly serious. According to the monitoring results of my country's major urban environmental monitoring centers, construction site dust is one of the important sources of inhalable particulate matter, and its contribution rate to PM10 in the air is as high as 3%-13%. The main hazards of dust on construction sites include: reducing visibility; endangering the health of residents; destroying the living environment and increasing the difficulty of cleaning the environment. [0003] Construction site dust refers to the dust r...

Problems solved by technology

The system has the following disadvantages: First, it uses activated carbon to absorb and filter the dust. The activated carbon has a significant effect on adsorbing gas, but its ability to absorb dust particles is weak, and it needs to be replaced frequently, which is economical. Second, the activated carbon filter is used to temporarily absorb the dust. Secondary treatment is carried out outside the system, but the particle size of inhalable particulate matter such as PM2.5 and PM10 has not changed. When secondary treatment such as activated carbon filter is replaced, inhalable particulate matter may still enter the air and cause certain hazards; The third is that the wind energy driving device uses the wind generated by the truck to drive the fan blades to rotate and collect dust. However, the trucks on the construction site generally travel at a slower speed and the wind force is weaker, resulting in a lower speed of the fan blades, which affects the dust collection efficiency of the wind energy driving device.
