Environment-friendly dust removal equipment for building engineering construction

The utility model discloses environment-friendly dust removal equipment for building engineering construction, and belongs to the technical field of construction environment-friendly equipment. The environment-friendly dust removal equipment for building engineering construction comprises a main body internally provided with a conical cavity, a top cover is installed at the top end of the main body, an exhaust pipe is installed in the middle of the top cover in a penetrating mode, and the bottom end of the exhaust pipe extends to the lower portion of the inner side of the main body. The dust collector is reasonable in structure, when high-speed airflow passes through the built-in guide vane, a swirling vortex is formed on the windward side of the guide vane to reduce the airflow speed, dust rubs against the side wall of the guide vane to reduce moving potential energy, the dust gradually settles under the action of gravity, airflow partition is conducted through the semi-ring cylinder, and the dust smoothly s
