Multi-stage dust falling systemand method for construction site

Abstract

The invention discloses a multi-stage dust falling system and method for a construction site. The system comprises a high-pressure gas pipeline, a water pipeline and a water spraying assembly. The tail end of the water pipeline communicates with the high-pressure gas pipeline, and the water spraying assembly is connected to the tail end of the high-pressure gas pipeline; the water spraying assembly comprises a water spraying shell, and the water spraying shell is provided with a front end inlet, a tail end outlet, a water channel, a particle inlet and an atomizing plate; the atomizing plate is positioned behind the tail end outlet, and the atomizing plate and the tail end outlet are arranged at an interval; a suction channel is arranged in the water channel, and the inner diameter of the suction channel is gradually reduced from front to back; and the particle inlet is located at the tail end of the suction channel and located in the water spraying shell. The device disclosed by the invention can achieve a dust falling effect, dust falling is carried out in two stages in the whole process, and part of dust particles are sucked into the water spraying shell through the suction channel; and a part of dust particles are wrapped by water mist dispersed from the atomizing plate and water, the dust falling effect can be achieved through a small amount of water, meanwhile, the two-stage dust falling effect is better, and implementation is convenient.

Description

technical field [0001] The invention belongs to the technical field of dust reduction, and in particular relates to a multi-stage dust reduction system and a dust reduction method for a construction site. Background technique [0002] Construction sites, garbage recycling plants, and muck transport vehicles will generate a lot of dust during operation, pollute the air, increase the concentration of PM2.5 and PM10, and affect human respiratory health. In order to prevent the above situations, it is necessary to carry out dust reduction treatment on places and equipment prone to dust generation. [0003] The measures to control dust pollution on the construction site mainly include: [0004] For materials with dust, the project department will contact the manufacturer and require the manufacturer to pack them in bags or containers. After the materials enter the site, the bags or containers will be recycled by the manufacturer. The project department will give the manufacturer...
