Abstract

The invention discloses road construction dust removing equipment, which belongs to the technical field of dust removing equipment and comprises a cyclone section, a spraying section and an adsorption section, wherein the cyclone section consists of a cyclone dust collector, two-phase separation is realized by utilizing the density difference between a medium phase and a particle phase in waste gas, after gas enters from an air inlet, the gas is converted into high-speed rotary motion from linear motion due to a special cone-shaped structure of a cyclone section separator, dust particles are thrown to a cylinder wall by centrifugal force far greater than self gravity and finally settled in a dust collecting box at the bottom of the cyclone dust collector, the efficient purification of waste gas with complex components is realized by a multistage sectional treatment mode, and the tangential speed of cyclone rising at the center of the cyclone section separator is reduced along with the increase of the depth of an exhaust pipe, so that tiny dust particles are more difficult to be carried away from the cyclone dust by the rising airflow, the settled dust is prevented from being raised again, and the separation efficiency is improved. The dust removal efficiency of road construction is improved.

Road construction dust collecting equipment Technical Field The invention belongs to the technical field of dust removal equipment, and particularly relates to road construction dust removal equipment. Background Road construction often produces a large amount of dust, and these dust not only can pollute the construction area, can also spread to surrounding areas along with the wind direction, causes harmful effect to atmospheric environment. Long-term high-concentration dust pollution can aggravate air pollution, influence air quality, and cause potential threat to ecological environment and biodiversity. Most dust contains various harmful substances such as particulate matters (PM 10, PM 2.5), heavy metals, organic matters and the like, which have adverse effects on human health. The constructor is exposed in a high-concentration dust environment for a long time, so that health problems such as respiratory diseases, cardiovascular diseases and the like are easily caused. Meanwhile, surrounding residents and pedestrians can be influenced by dust pollution, and the physical health of the residents and pedestrians is damaged. Therefore, performing environmental protection and dust removal is an important measure for protecting constructors and public health; At present, a plurality of water pipes are arranged on the side part of the protective wall, atomizing spray heads are arranged at intervals, water flows form water mist to remove dust around through the cooperation of the water pipes and the atomizing spray heads, but the spraying range of the atomizing spray heads is fixed, so that dust cannot be removed in different ranges of the far and the near, tiny dust particles at the near end are easily carried up by ascending air flow, and settled dust is lifted again, so that the dust removing effect is not improved.
