Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention devices for construction, in particular to a dust prevention device for civil engineering construction. Background Technique

[0002] Dust prevention devices are essential environmental protection facilities in modern construction. They aim to reduce the dust generated during construction activities, protect the health of on-site workers, maintain the quality of the surrounding environment, and comply with national and regional air pollution prevention and control laws and regulations. Usually, a fog cannon machine is used for regular dust removal work.

[0003] Among them, the core working principle of the fog cannon machine is to pressurize water using a high-pressure pump, and then atomize the water droplets into micron-sized fine water mist particles through a special atomizing nozzle. These extremely fine water mist particles are pushed to a long distance under the action of a high-pressure fan to form a dense and uniform water mist curtain. The atomized water mist contacts and combines with pollutants such as dust and PM2.5 in the air and then settles, achieving the effect of air purification and dust reduction. Compared with the traditional watering method, the water resource consumption of the fog cannon machine is reduced by 70 - 80%, but its spraying coverage area is wider, several times that of an ordinary watering truck, improving the work efficiency.

[0004] Reference can be made to the patent with the patent number CN219308271U. This patent discloses an engineering construction dust removal device, including a base frame body. A placement frame is provided on the top of the base frame body. A lifting assembly is provided between the placement frame and the base frame body. A water storage tank is provided on the top of the placement frame. A spray barrel body is provided on the top of the water storage tank. An adjustment assembly is provided between the water storage tank and the spray barrel body. The bottom of the water storage tank is fixedly connected with a rotating rod. The bottom end of the rotating rod passes through the top of the placement frame and extends into the interior of the placement frame. The rotating rod is rotatably connected with the placement frame. A driving motor is fixedly connected inside the placement frame. For this engineering construction dust removal device, the output end of the driving motor drives the rotating rod to rotate, and the rotating rod drives the water storage tank to rotate, so that the spray barrel body is in a rotating state, enabling the spray barrel body to meet the need for dust removal in different directions and improving the dust removal effect.

[0005] Although this patent has the effect of dust reduction for dust, since this dust removal device essentially performs post-treatment on the already generated dust, and realizes the sinking of dust by spraying water mist particles to achieve the effect of dust suppression. However, when this dust removal equipment is not working, the dust that has fallen to the ground due to contact with water mist particles will experience water evaporation, resulting in the problem that the dust will rise again. This means that this dust removal device can only inhibit the impact of dust and cannot effectively remove the dust accumulated at the construction site. Therefore, to solve the above problems, the utility model provides a dust prevention device for civil engineering construction. Content of the Utility Model
