Abstract

The invention discloses a cage washing dust collector used in building and a working method thereof. The dust collector comprises a dusty gas inlet, a dust chamber, a clean gas outlet, a water-sending system, a clean-water reservoir, a sewage discharge pipe, a cesspool, an air dust density detector, a holder, and a control system. The dusty gas enters the dust chamber from the bottom through the dusty gas inlet, and the water-sending system sends clear water to the dust chamber. The clear gas treated by the dust chamber is discharged from the dust chamber through the clean gas outlet, and the sewage is discharged into the cesspool through the sewage discharge pipe. The cage washing dust collector used in building and the working method thereof have novel and reasonable structure, have high gas suspension dust removal rate, and have wide range of application.

Description

technical field [0001] The invention belongs to construction engineering devices, in particular to a construction cage cleaning and dust removal device and a working method thereof. Background technique [0002] Environmental protection has become the focus of the world's attention. The tide of economic globalization and the call for solving global environmental problems have made the relationship between environment and trade increasingly close. International organizations have formulated a series of technical standards aimed at protecting the environment. How to prevent and control air pollution and clean the air environment is also a subject of continuous research. Especially in my country's construction dust removal, a large amount of dust will be generated during the construction process, which seriously pollutes the atmospheric environment. The fine coal dust in the air, especially the floating dust with a diameter of 2.5-6 μm, is extremely harmful to human health. I...
