Abstract

The invention discloses an environment-friendly facility for an asphalt mixing plant, which belongs to the field of supporting facilities of asphalt mixing equipment and is characterized in that raised dust and waste gas in a screening bin, a metering bin, a mixing cylinder and a drying roller in the mixing plant are guided into a combustion cylinder for combustion treatment through a fan. After asphalt flue gas is combusted, harmful ingredients in gas can be eliminated, meanwhile, solid ash generated after combustible parts in dust are combusted settles on a dust isolation net of a combustion cylinder, waste gas generated after combustion enters a spraying cylinder, the spraying cylinder is filled with water, solid particles and water-soluble ingredients in the waste gas can be left in the water, the waste gas is subjected to secondary purification by water mist sprayed by the spraying head after floating out of the water, so that the waste gas and dust are fully removed. In addition, combustion cylinders are arranged among the spraying tank, the drying roller and the mixing plant, so that the influence on the quality of finished products caused by backward flowing of water vapor is effectively prevented.

Description

technical field [0001] The invention relates to the field of asphalt mixing supporting devices, and more specifically, relates to an environmental protection facility of an asphalt mixing plant. Background technique [0002] With the development of economy, the process of urbanization is accelerated. In urban construction, asphalt mixture is an important building material, mainly used in road traffic construction. The production process of asphalt mixture is accompanied by a large amount of dust and asphalt fume, which will have a serious impact on the human body and the environment. Therefore, the environmental protection transformation of asphalt mixing plants is becoming more and more popular. Existing asphalt mixing plants mainly recover dust through the ventilation equipment, and the dust is guided by the ventilation equipment through the pipeline to the bag filter for recycling. In this way, the dust removal effect is not good, and the exhaust gas is not purified. C...
