Description

Technical Field

[0002] Construction projects usually generate a lot of dust, such as the processing and construction of cement, gypsum, wood, sand and gravel. Long-term exposure to high-concentration dust environments can damage workers' respiratory systems and lead to health problems such as respiratory diseases. Therefore, installing dust removal devices can help reduce the dust content in the air, protect the health of workers, and keep the surrounding environment clean and healthy.

[0003] In the prior art, there are two types of dust removal devices and spray devices. Common dust removal devices use gravity sedimentation to make dust particles affected by gas flow and settle to the bottom, intercept dust particles in the air, and filter clean gas, intercept dust particles in the air, pass clean gas, and then discharge clean gas through the outlet at the top of the dust collector. Common spray devices use spray technology and the interaction between liquid and gas to spray liquid (usually water) into the air to adsorb dust particles in the air to the surface of droplets, thereby achieving the purpose of cleaning the air. However, existing dust removal devices cannot achieve the effect of spray devices, and do not take into account that the water sprayed by the spray device will wet the clothes of passers-by. The water sprayed by the spray device cannot be recycled, which will cause a waste of water resources. For this reason, a green dust removal device for construction projects is proposed.
