Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining facility technology, specifically a wet dust removal fan for mining tunneling. Background Technology
[0002] Dust generated during mining operations not only endangers workers' health (such as causing pneumoconiosis) but may also pose an explosion risk. Therefore, wet dust collectors are key equipment for safe production in mines. Wet dust collectors draw in dust-laden air through a fan, use a spray system to mix and condense the dust with water mist, and then separate the mud and water through a dehydration device. The purified air is then discharged, thus achieving dust suppression.
[0003] The existing wet dust collectors used in mining tunneling still have the following problems: their dust removal efficiency is insufficient. The traditional nozzle atomization structure usually adopts a top-mounted single nozzle structure design, combined with its single air guide pipe structure design. The contact efficiency between the sprayed water mist and the dust in the airflow is limited, making it difficult to effectively capture the dust in the airflow. In addition, its dehydration device is usually a metal filter screen, which is prone to clogging and affects the dehydration work. Furthermore, since it is usually fixedly installed inside the dust collector box, its cleaning and maintenance are relatively inconvenient. Utility Model Content
