Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression equipment, in particular to a water spraying dust suppression device for building construction projects. Background Art

[0002] The fine dust particles on construction sites are dangerous. Once inhaled, dust can reduce a person's lung capacity and increase overall stress on the heart, which can lead to a variety of diseases. If you keep coughing during a construction project, you may be inhaling dangerous amounts of construction dust. Construction dust is not only harmful to workers, but it can also cause serious damage to construction equipment. Once construction equipment is covered with a lot of dust, the equipment must be maintained more frequently due to engine wear, which leads to an increase in overall operating costs.

[0003] At present, the dust reduction method for building construction projects is generally water spraying. However, the existing water spraying dust reduction devices generally use one-way nozzles to spray water to reduce dust. In order to improve the dust reduction effect, it is necessary to increase the corresponding number of nozzles and water pipes, which will greatly increase equipment expenses. Therefore, we have introduced a new water spraying dust reduction device for building construction projects. Utility Model Content
