Description

Technical Field

[0001] The invention relates to the technical field of dust removal in building construction, and in particular to dust removal equipment for building construction. Background Art

[0002] With the acceleration of urbanization, construction activities are becoming more frequent, and dust pollution generated during construction has become one of the problems that need to be solved urgently. Construction dust not only affects the air quality of the construction site and the surrounding environment, but may also have an adverse impact on the health of construction workers and surrounding residents. Therefore, taking effective measures to control and reduce construction dust is of great significance to improving urban environmental quality and protecting public health.

[0003] The most commonly used dust suppression device on construction sites is the dust suppression fog cannon, also known as spray dust removal equipment or spray dust suppressor, which is a professional equipment specially designed to reduce dust and particulate matter in the air. It uses high pressure to atomize water into tiny water droplets, which can combine with dust particles in the air, making the dust particles heavier and then settle to the ground, thereby achieving the effect of dust reduction. Fog cannons are widely used in construction sites, mines, ports, landfills and other places prone to dust generation, and are an important means of effectively controlling environmental pollution.

[0004] The working principle of fog cannon mainly includes the following: 1. Water atomization: Water is pressed into a special nozzle through a high-pressure pump, and the nozzle breaks the water flow into fine water mist particles. 2. Aerodynamic effect: The diameter of the water mist particles produced by the fog cannon is very small, generally between a few microns and tens of microns. This size allows them to float in the air for a period of time and collide with dust particles in the air. 3. Dust sedimentation: When the water mist particles come into contact with dust particles, they will adhere to their surface, increase the mass of the dust particles, and accelerate their sedimentation.

[0005] The existing fog cannon mainly includes a base and a cylinder, and both ends of the cylinder are open. When the fog cannon is not in use, external dirt can easily enter the cylinder, which can easily affect the normal operation of the fog cannon and cause the dust reduction work to fail to operate normally.

[0006] Therefore, a dust removal device for building construction is needed to solve the above problems. Summary of the invention
